- * Derived from asm-x86/semaphore.h
- *
- *
- * The MSW of the count is the negated number of active writers and waiting
- * lockers, and the LSW is the total number of active locks
- *
- * The lock count is initialized to 0 (no active and no waiting lockers).
- *
- * When a writer subtracts WRITE_BIAS, it'll get 0xffff0001 for the case of an
- * uncontended lock. This can be determined because XADD returns the old value.
- * Readers increment by 1 and see a positive value when uncontended, negative
- * if there are writers (and maybe) readers waiting (in which case it goes to
- * sleep).
- *
- * The value of WAITING_BIAS supports up to 32766 waiting processes. This can
- * be extended to 65534 by manually checking the whole MSW rather than relying
- * on the S flag.
- *
- * The value of ACTIVE_BIAS supports up to 65535 active processes.
- *
- * This should be totally fair - if anything is waiting, a process that wants a
- * lock will go to the back of the queue. When the currently active lock is
- * released, if there's a writer at the front of the queue, then that and only
- * that will be woken up; if there's a bunch of consecutive readers at the

+/**
+ * DOC: overview
+ *
+ * The Performance and Energy Bias Hint (EPB) allows software to specify its
+ * preference with respect to the power-performance tradeoffs present in the
+ * processor.  Generally, the EPB is expected to be set by user space (directly
+ * via sysfs or with the help of the x86_energy_perf_policy tool), but there are
+ * two reasons for the kernel to update it.
+ *
+ * First, there are systems where the platform firmware resets the EPB during
+ * system-wide transitions from sleep states back into the working state
+ * effectively causing the previous EPB updates by user space to be lost.
+ * Thus the kernel needs to save the current EPB values for all CPUs during
+ * system-wide transitions to sleep states and restore them on the way back to
+ * the working state.  That can be achieved by saving EPB for secondary CPUs
+ * when they are taken offline during transitions into system sleep states and
+ * for the boot CPU in a syscore suspend operation, so that it can be restored
+ * for the boot CPU in a syscore resume operation and for the other CPUs when
+ * they are brought back online.  However, CPUs that are already offline when
+ * a system-wide PM transition is started are not taken offline again, but their
+ * EPB values may still be reset by the platform firmware during the transition,
+ * so in fact it is necessary to save the EPB of any CPU taken offline and to
+ * restore it when the given CPU goes back online at all times.
+ *
+ * Second, on many systems the initial EPB value coming from the platform
+ * firmware is 0 ('performance') and at least on some of them that is because
+ * the platform firmware does not initialize EPB at all with the assumption that
+ * the OS will do that anyway.  That sometimes is problematic, as it may cause
+ * the system battery to drain too fast, for example, so it is better to adjust
+ * it on CPU bring-up and if the initial EPB value for a given CPU is 0, the
+ * kernel changes it to 6 ('normal').

 /*
+ * The processes associated with bfqq may happen to generate their
+ * cumulative I/O at a lower rate than the rate at which the device
+ * could serve the same I/O. This is rather probable, e.g., if only
+ * one process is associated with bfqq and the device is an SSD. It
+ * results in bfqq becoming often empty while in service. In this
+ * respect, if BFQ is allowed to switch to another queue when bfqq
+ * remains empty, then the device goes on being fed with I/O requests,
+ * and the throughput is not affected. In contrast, if BFQ is not
+ * allowed to switch to another queue---because bfqq is sync and
+ * I/O-dispatch needs to be plugged while bfqq is temporarily
+ * empty---then, during the service of bfqq, there will be frequent
+ * "service holes", i.e., time intervals during which bfqq gets empty
+ * and the device can only consume the I/O already queued in its
+ * hardware queues. During service holes, the device may even get to
+ * remaining idle. In the end, during the service of bfqq, the device
+ * is driven at a lower speed than the one it can reach with the kind
+ * of I/O flowing through bfqq.
+ *
+ * To counter this loss of throughput, BFQ implements a "request
+ * injection mechanism", which tries to fill the above service holes
+ * with I/O requests taken from other queues. The hard part in this
+ * mechanism is finding the right amount of I/O to inject, so as to
+ * both boost throughput and not break bfqq's bandwidth and latency
+ * guarantees. In this respect, the mechanism maintains a per-queue
+ * inject limit, computed as below. While bfqq is empty, the injection
+ * mechanism dispatches extra I/O requests only until the total number
+ * of I/O requests in flight---i.e., already dispatched but not yet
+ * completed---remains lower than this limit.
+ *
+ * A first definition comes in handy to introduce the algorithm by
+ * which the inject limit is computed.  We define as first request for
+ * bfqq, an I/O request for bfqq that arrives while bfqq is in
+ * service, and causes bfqq to switch from empty to non-empty. The
+ * algorithm updates the limit as a function of the effect of
+ * injection on the service times of only the first requests of
+ * bfqq. The reason for this restriction is that these are the
+ * requests whose service time is affected most, because they are the
+ * first to arrive after injection possibly occurred.
+ *
+ * To evaluate the effect of injection, the algorithm measures the
+ * "total service time" of first requests. We define as total service
+ * time of an I/O request, the time that elapses since when the
+ * request is enqueued into bfqq, to when it is completed. This
+ * quantity allows the whole effect of injection to be measured. It is
+ * easy to see why. Suppose that some requests of other queues are
+ * actually injected while bfqq is empty, and that a new request R
+ * then arrives for bfqq. If the device does start to serve all or
+ * part of the injected requests during the service hole, then,
+ * because of this extra service, it may delay the next invocation of
+ * the dispatch hook of BFQ. Then, even after R gets eventually
+ * dispatched, the device may delay the actual service of R if it is
+ * still busy serving the extra requests, or if it decides to serve,
+ * before R, some extra request still present in its queues. As a
+ * conclusion, the cumulative extra delay caused by injection can be
+ * easily evaluated by just comparing the total service time of first
+ * requests with and without injection.
+ *
+ * The limit-update algorithm works as follows. On the arrival of a
+ * first request of bfqq, the algorithm measures the total time of the
+ * request only if one of the three cases below holds, and, for each
+ * case, it updates the limit as described below:
+ *
+ * (1) If there is no in-flight request. This gives a baseline for the
+ *     total service time of the requests of bfqq. If the baseline has
+ *     not been computed yet, then, after computing it, the limit is
+ *     set to 1, to start boosting throughput, and to prepare the
+ *     ground for the next case. If the baseline has already been
+ *     computed, then it is updated, in case it results to be lower
+ *     than the previous value.
+ *
+ * (2) If the limit is higher than 0 and there are in-flight
+ *     requests. By comparing the total service time in this case with
+ *     the above baseline, it is possible to know at which extent the
+ *     current value of the limit is inflating the total service
+ *     time. If the inflation is below a certain threshold, then bfqq
+ *     is assumed to be suffering from no perceivable loss of its
+ *     service guarantees, and the limit is even tentatively
+ *     increased. If the inflation is above the threshold, then the
+ *     limit is decreased. Due to the lack of any hysteresis, this
+ *     logic makes the limit oscillate even in steady workload
+ *     conditions. Yet we opted for it, because it is fast in reaching
+ *     the best value for the limit, as a function of the current I/O
+ *     workload. To reduce oscillations, this step is disabled for a
+ *     short time interval after the limit happens to be decreased.
+ *
+ * (3) Periodically, after resetting the limit, to make sure that the
+ *     limit eventually drops in case the workload changes. This is
+ *     needed because, after the limit has gone safely up for a
+ *     certain workload, it is impossible to guess whether the
+ *     baseline total service time may have changed, without measuring
+ *     it again without injection. A more effective version of this
+ *     step might be to just sample the baseline, by interrupting
+ *     injection only once, and then to reset/lower the limit only if
+ *     the total service time with the current limit does happen to be
+ *     too large.
+ *
+ * More details on each step are provided in the comments on the
+ * pieces of code that implement these steps: the branch handling the
+ * transition from empty to non empty in bfq_add_request(), the branch
+ * handling injection in bfq_select_queue(), and the function
+ * bfq_choose_bfqq_for_injection(). These comments also explain some
+ * exceptions, made by the injection mechanism in some special cases.

+Description:
+		As part of Chrome OS's FAFT (Fully Automated Firmware Testing)
+		tests, we need to ensure that the H1 chip is properly setting
+		some GPIO lines. The h1_gpio attribute exposes the state

 KernelVersion:	5.1
 Description:
 		Write and read raw mailbox commands to the EC.
 
-		For writing:
-		Bytes 0-1 indicate the message type:
-			00 F0 = Execute Legacy Command
-			00 F2 = Read/Write NVRAM Property
-		Byte 2 provides the command code
-		Bytes 3+ consist of the data passed in the request
+		You can write a hexadecimal sentence to raw, and that series of
+		bytes will be sent to the EC. Then, you can read the bytes of
+		response by reading from raw.
 
-		At least three bytes are required, for the msg type and command,
-		with additional bytes optional for additional data.
+		For writing, bytes 0-1 indicate the message type, one of enum
+		wilco_ec_msg_type. Byte 2+ consist of the data passed in the
+		request, starting at MBOX[0]
+
+		At least three bytes are required for writing, two for the type
+		and at least a single byte of data. Only the first
+		EC_MAILBOX_DATA_SIZE bytes of MBOX will be used.
 
 		Example:
 		// Request EC info type 3 (EC firmware build date)
-		$ echo 00 f0 38 00 03 00 > raw
+		// Corresponds with sending type 0x00f0 with
+		// MBOX = [38, 00, 03, 00]
+		$ echo 00 f0 38 00 03 00 > /sys/kernel/debug/wilco_ec/raw
 		// View the result. The decoded ASCII result "12/21/18" is
 		// included after the raw hex.
-		$ cat raw
-		00 31 32 2f 32 31 2f 31 38 00 38 00 01 00 2f 00  .12/21/18.8...
+		// Corresponds with MBOX = [00, 00, 31, 32, 2f, 32, 31, 38, ...]
+		$ cat /sys/kernel/debug/wilco_ec/raw
+		00 00 31 32 2f 32 31 2f 31 38 00 38 00 01 00 2f 00  ..12/21/18.8...
+
+		Note that the first 32 bytes of the received MBOX[] will be
+		printed, even if some of the data is junk. It is up to you to
+		know how many of the first bytes of data are the actual
+		response.

+Monitoring for pressure thresholds
+==================================
+
+Users can register triggers and use poll() to be woken up when resource
+pressure exceeds certain thresholds.
+
+A trigger describes the maximum cumulative stall time over a specific
+time window, e.g. 100ms of total stall time within any 500ms window to
+generate a wakeup event.
+
+To register a trigger user has to open psi interface file under
+/proc/pressure/ representing the resource to be monitored and write the
+desired threshold and time window. The open file descriptor should be
+used to wait for trigger events using select(), poll() or epoll().
+The following format is used:
+
+<some|full> <stall amount in us> <time window in us>
+
+For example writing "some 150000 1000000" into /proc/pressure/memory
+would add 150ms threshold for partial memory stall measured within
+1sec time window. Writing "full 50000 1000000" into /proc/pressure/io
+would add 50ms threshold for full io stall measured within 1sec time window.
+
+Triggers can be set on more than one psi metric and more than one trigger
+for the same psi metric can be specified. However for each trigger a separate
+file descriptor is required to be able to poll it separately from others,
+therefore for each trigger a separate open() syscall should be made even
+when opening the same psi interface file.
+
+Monitors activate only when system enters stall state for the monitored
+psi metric and deactivates upon exit from the stall state. While system is
+in the stall state psi signal growth is monitored at a rate of 10 times per
+tracking window.
+
+The kernel accepts window sizes ranging from 500ms to 10s, therefore min
+monitoring update interval is 50ms and max is 1s. Min limit is set to
+prevent overly frequent polling. Max limit is chosen as a high enough number
+after which monitors are most likely not needed and psi averages can be used
+instead.
+
+When activated, psi monitor stays active for at least the duration of one
+tracking window to avoid repeated activations/deactivations when system is
+bouncing in and out of the stall state.
+
+Notifications to the userspace are rate-limited to one per tracking window.
+
+The trigger will de-register when the file descriptor used to define the
+trigger  is closed.

-Special Usage Model of the ACPI Control Method Lid Device
-
-Copyright (C) 2016, Intel Corporation
-Author: Lv Zheng <lv.zheng@intel.com>
-
-
-Abstract:
-
-Platforms containing lids convey lid state (open/close) to OSPMs using a
-control method lid device. To implement this, the AML tables issue
-Notify(lid_device, 0x80) to notify the OSPMs whenever the lid state has
-changed. The _LID control method for the lid device must be implemented to
-report the "current" state of the lid as either "opened" or "closed".
-
-For most platforms, both the _LID method and the lid notifications are
-reliable. However, there are exceptions. In order to work with these
-exceptional buggy platforms, special restrictions and expections should be
-taken into account. This document describes the restrictions and the
-expections of the Linux ACPI lid device driver.
-
-
-1. Restrictions of the returning value of the _LID control method
-
-The _LID control method is described to return the "current" lid state.
-However the word of "current" has ambiguity, some buggy AML tables return
-the lid state upon the last lid notification instead of returning the lid
-state upon the last _LID evaluation. There won't be difference when the
-_LID control method is evaluated during the runtime, the problem is its
-initial returning value. When the AML tables implement this control method
-with cached value, the initial returning value is likely not reliable.
-There are platforms always retun "closed" as initial lid state.
-
-2. Restrictions of the lid state change notifications
-
-There are buggy AML tables never notifying when the lid device state is
-changed to "opened". Thus the "opened" notification is not guaranteed. But
-it is guaranteed that the AML tables always notify "closed" when the lid
-state is changed to "closed". The "closed" notification is normally used to
-trigger some system power saving operations on Windows. Since it is fully
-tested, it is reliable from all AML tables.
-
-3. Expections for the userspace users of the ACPI lid device driver
-
-The ACPI button driver exports the lid state to the userspace via the
-following file:
-  /proc/acpi/button/lid/LID0/state
-This file actually calls the _LID control method described above. And given
-the previous explanation, it is not reliable enough on some platforms. So
-it is advised for the userspace program to not to solely rely on this file
-to determine the actual lid state.
-
-The ACPI button driver emits the following input event to the userspace:
-  SW_LID
-The ACPI lid device driver is implemented to try to deliver the platform
-triggered events to the userspace. However, given the fact that the buggy
-firmware cannot make sure "opened"/"closed" events are paired, the ACPI
-button driver uses the following 3 modes in order not to trigger issues.
-
-If the userspace hasn't been prepared to ignore the unreliable "opened"
-events and the unreliable initial state notification, Linux users can use
-the following kernel parameters to handle the possible issues:
-A. button.lid_init_state=method:
-   When this option is specified, the ACPI button driver reports the
-   initial lid state using the returning value of the _LID control method
-   and whether the "opened"/"closed" events are paired fully relies on the
-   firmware implementation.
-   This option can be used to fix some platforms where the returning value
-   of the _LID control method is reliable but the initial lid state
-   notification is missing.
-   This option is the default behavior during the period the userspace
-   isn't ready to handle the buggy AML tables.
-B. button.lid_init_state=open:
-   When this option is specified, the ACPI button driver always reports the
-   initial lid state as "opened" and whether the "opened"/"closed" events
-   are paired fully relies on the firmware implementation.
-   This may fix some platforms where the returning value of the _LID
-   control method is not reliable and the initial lid state notification is
-   missing.
-
-If the userspace has been prepared to ignore the unreliable "opened" events
-and the unreliable initial state notification, Linux users should always
-use the following kernel parameter:
-C. button.lid_init_state=ignore:
-   When this option is specified, the ACPI button driver never reports the
-   initial lid state and there is a compensation mechanism implemented to
-   ensure that the reliable "closed" notifications can always be delievered
-   to the userspace by always pairing "closed" input events with complement
-   "opened" input events. But there is still no guarantee that the "opened"
-   notifications can be delivered to the userspace when the lid is actually
-   opens given that some AML tables do not send "opened" notifications
-   reliably.
-   In this mode, if everything is correctly implemented by the platform
-   firmware, the old userspace programs should still work. Otherwise, the
-   new userspace programs are required to work with the ACPI button driver.
-   This option will be the default behavior after the userspace is ready to
-   handle the buggy AML tables.

-The AML Debugger
-
-Copyright (C) 2016, Intel Corporation
-Author: Lv Zheng <lv.zheng@intel.com>
-
-
-This document describes the usage of the AML debugger embedded in the Linux
-kernel.
-
-1. Build the debugger
-
-   The following kernel configuration items are required to enable the AML
-   debugger interface from the Linux kernel:
-
-   CONFIG_ACPI_DEBUGGER=y
-   CONFIG_ACPI_DEBUGGER_USER=m
-
-   The userspace utilities can be built from the kernel source tree using
-   the following commands:
-
-   $ cd tools
-   $ make acpi
-
-   The resultant userspace tool binary is then located at:
-
-     tools/power/acpi/acpidbg
-
-   It can be installed to system directories by running "make install" (as a
-   sufficiently privileged user).
-
-2. Start the userspace debugger interface
-
-   After booting the kernel with the debugger built-in, the debugger can be
-   started by using the following commands:
-
-   # mount -t debugfs none /sys/kernel/debug
-   # modprobe acpi_dbg
-   # tools/power/acpi/acpidbg
-
-   That spawns the interactive AML debugger environment where you can execute
-   debugger commands.
-
-   The commands are documented in the "ACPICA Overview and Programmer Reference"
-   that can be downloaded from
-
-   https://acpica.org/documentation
-
-   The detailed debugger commands reference is located in Chapter 12 "ACPICA
-   Debugger Reference".  The "help" command can be used for a quick reference.
-
-3. Stop the userspace debugger interface
-
-   The interactive debugger interface can be closed by pressing Ctrl+C or using
-   the "quit" or "exit" commands.  When finished, unload the module with:
-
-   # rmmod acpi_dbg
-
-   The module unloading may fail if there is an acpidbg instance running.
-
-4. Run the debugger in a script
-
-   It may be useful to run the AML debugger in a test script. "acpidbg" supports
-   this in a special "batch" mode.  For example, the following command outputs
-   the entire ACPI namespace:
-
-   # acpidbg -b "namespace"

-			APEI Error INJection
-			~~~~~~~~~~~~~~~~~~~~
-
-EINJ provides a hardware error injection mechanism. It is very useful
-for debugging and testing APEI and RAS features in general.
-
-You need to check whether your BIOS supports EINJ first. For that, look
-for early boot messages similar to this one:
-
-ACPI: EINJ 0x000000007370A000 000150 (v01 INTEL           00000001 INTL 00000001)
-
-which shows that the BIOS is exposing an EINJ table - it is the
-mechanism through which the injection is done.
-
-Alternatively, look in /sys/firmware/acpi/tables for an "EINJ" file,
-which is a different representation of the same thing.
-
-It doesn't necessarily mean that EINJ is not supported if those above
-don't exist: before you give up, go into BIOS setup to see if the BIOS
-has an option to enable error injection. Look for something called WHEA
-or similar. Often, you need to enable an ACPI5 support option prior, in
-order to see the APEI,EINJ,... functionality supported and exposed by
-the BIOS menu.
-
-To use EINJ, make sure the following are options enabled in your kernel
-configuration:
-
-CONFIG_DEBUG_FS
-CONFIG_ACPI_APEI
-CONFIG_ACPI_APEI_EINJ
-
-The EINJ user interface is in <debugfs mount point>/apei/einj.
-
-The following files belong to it:
-
-- available_error_type
-
-  This file shows which error types are supported:
-
-  Error Type Value	Error Description
-  ================	=================
-  0x00000001		Processor Correctable
-  0x00000002		Processor Uncorrectable non-fatal
-  0x00000004		Processor Uncorrectable fatal
-  0x00000008		Memory Correctable
-  0x00000010		Memory Uncorrectable non-fatal
-  0x00000020		Memory Uncorrectable fatal
-  0x00000040		PCI Express Correctable
-  0x00000080		PCI Express Uncorrectable fatal
-  0x00000100		PCI Express Uncorrectable non-fatal
-  0x00000200		Platform Correctable
-  0x00000400		Platform Uncorrectable non-fatal
-  0x00000800		Platform Uncorrectable fatal
-
-  The format of the file contents are as above, except present are only
-  the available error types.
-
-- error_type
-
-  Set the value of the error type being injected. Possible error types
-  are defined in the file available_error_type above.
-
-- error_inject
-
-  Write any integer to this file to trigger the error injection. Make
-  sure you have specified all necessary error parameters, i.e. this
-  write should be the last step when injecting errors.
-
-- flags
-
-  Present for kernel versions 3.13 and above. Used to specify which
-  of param{1..4} are valid and should be used by the firmware during
-  injection. Value is a bitmask as specified in ACPI5.0 spec for the
-  SET_ERROR_TYPE_WITH_ADDRESS data structure:
-
-	Bit 0 - Processor APIC field valid (see param3 below).
-	Bit 1 - Memory address and mask valid (param1 and param2).
-	Bit 2 - PCIe (seg,bus,dev,fn) valid (see param4 below).
-
-  If set to zero, legacy behavior is mimicked where the type of
-  injection specifies just one bit set, and param1 is multiplexed.
-
-- param1
-
-  This file is used to set the first error parameter value. Its effect
-  depends on the error type specified in error_type. For example, if
-  error type is memory related type, the param1 should be a valid
-  physical memory address. [Unless "flag" is set - see above]
-
-- param2
-
-  Same use as param1 above. For example, if error type is of memory
-  related type, then param2 should be a physical memory address mask.
-  Linux requires page or narrower granularity, say, 0xfffffffffffff000.
-
-- param3
-
-  Used when the 0x1 bit is set in "flags" to specify the APIC id
-
-- param4
-  Used when the 0x4 bit is set in "flags" to specify target PCIe device
-
-- notrigger
-
-  The error injection mechanism is a two-step process. First inject the
-  error, then perform some actions to trigger it. Setting "notrigger"
-  to 1 skips the trigger phase, which *may* allow the user to cause the
-  error in some other context by a simple access to the CPU, memory
-  location, or device that is the target of the error injection. Whether
-  this actually works depends on what operations the BIOS actually
-  includes in the trigger phase.
-
-BIOS versions based on the ACPI 4.0 specification have limited options
-in controlling where the errors are injected. Your BIOS may support an
-extension (enabled with the param_extension=1 module parameter, or boot
-command line einj.param_extension=1). This allows the address and mask
-for memory injections to be specified by the param1 and param2 files in
-apei/einj.
-
-BIOS versions based on the ACPI 5.0 specification have more control over
-the target of the injection. For processor-related errors (type 0x1, 0x2
-and 0x4), you can set flags to 0x3 (param3 for bit 0, and param1 and
-param2 for bit 1) so that you have more information added to the error
-signature being injected. The actual data passed is this:
-
-	memory_address = param1;
-	memory_address_range = param2;
-	apicid = param3;
-	pcie_sbdf = param4;
-
-For memory errors (type 0x8, 0x10 and 0x20) the address is set using
-param1 with a mask in param2 (0x0 is equivalent to all ones). For PCI
-express errors (type 0x40, 0x80 and 0x100) the segment, bus, device and
-function are specified using param1:
-
-         31     24 23    16 15    11 10      8  7        0
-	+-------------------------------------------------+
-	| segment |   bus  | device | function | reserved |
-	+-------------------------------------------------+
-
-Anyway, you get the idea, if there's doubt just take a look at the code
-in drivers/acpi/apei/einj.c.
-
-An ACPI 5.0 BIOS may also allow vendor-specific errors to be injected.
-In this case a file named vendor will contain identifying information
-from the BIOS that hopefully will allow an application wishing to use
-the vendor-specific extension to tell that they are running on a BIOS
-that supports it. All vendor extensions have the 0x80000000 bit set in
-error_type. A file vendor_flags controls the interpretation of param1
-and param2 (1 = PROCESSOR, 2 = MEMORY, 4 = PCI). See your BIOS vendor
-documentation for details (and expect changes to this API if vendors
-creativity in using this feature expands beyond our expectations).
-
-
-An error injection example:
-
-# cd /sys/kernel/debug/apei/einj
-# cat available_error_type		# See which errors can be injected
-0x00000002	Processor Uncorrectable non-fatal
-0x00000008	Memory Correctable
-0x00000010	Memory Uncorrectable non-fatal
-# echo 0x12345000 > param1		# Set memory address for injection
-# echo $((-1 << 12)) > param2		# Mask 0xfffffffffffff000 - anywhere in this page
-# echo 0x8 > error_type			# Choose correctable memory error
-# echo 1 > error_inject			# Inject now
-
-You should see something like this in dmesg:
-

-			ACPI Debug Output
-
-
-The ACPI CA, the Linux ACPI core, and some ACPI drivers can generate debug
-output.  This document describes how to use this facility.
-
-Compile-time configuration
---------------------------
-
-ACPI debug output is globally enabled by CONFIG_ACPI_DEBUG.  If this config
-option is turned off, the debug messages are not even built into the
-kernel.
-
-Boot- and run-time configuration
---------------------------------
-
-When CONFIG_ACPI_DEBUG=y, you can select the component and level of messages
-you're interested in.  At boot-time, use the acpi.debug_layer and
-acpi.debug_level kernel command line options.  After boot, you can use the
-debug_layer and debug_level files in /sys/module/acpi/parameters/ to control
-the debug messages.
-
-debug_layer (component)
------------------------
-
-The "debug_layer" is a mask that selects components of interest, e.g., a
-specific driver or part of the ACPI interpreter.  To build the debug_layer
-bitmask, look for the "#define _COMPONENT" in an ACPI source file.
-
-You can set the debug_layer mask at boot-time using the acpi.debug_layer
-command line argument, and you can change it after boot by writing values
-to /sys/module/acpi/parameters/debug_layer.
-
-The possible components are defined in include/acpi/acoutput.h and
-include/acpi/acpi_drivers.h.  Reading /sys/module/acpi/parameters/debug_layer
-shows the supported mask values, currently these:
-
-    ACPI_UTILITIES                  0x00000001
-    ACPI_HARDWARE                   0x00000002

-    ACPI_PROCESSOR_COMPONENT        0x20000000
-
-debug_level
------------
-
-The "debug_level" is a mask that selects different types of messages, e.g.,
-those related to initialization, method execution, informational messages, etc.
-To build debug_level, look at the level specified in an ACPI_DEBUG_PRINT()
-statement.
-
-The ACPI interpreter uses several different levels, but the Linux
-ACPI core and ACPI drivers generally only use ACPI_LV_INFO.
-
-You can set the debug_level mask at boot-time using the acpi.debug_level
-command line argument, and you can change it after boot by writing values
-to /sys/module/acpi/parameters/debug_level.
-
-The possible levels are defined in include/acpi/acoutput.h.  Reading
-/sys/module/acpi/parameters/debug_level shows the supported mask values,
-currently these:
-
-    ACPI_LV_INIT                    0x00000001
-    ACPI_LV_DEBUG_OBJECT            0x00000002
-    ACPI_LV_INFO                    0x00000004

-Referencing hierarchical data nodes
------------------------------------
-
-ACPI in general allows referring to device objects in the tree only.
-Hierarchical data extension nodes may not be referred to directly, hence this
-document defines a scheme to implement such references.
-
-A reference consist of the device object name followed by one or more
-hierarchical data extension [1] keys. Specifically, the hierarchical data
-extension node which is referred to by the key shall lie directly under the
-parent object i.e. either the device object or another hierarchical data
-extension node.
-
-The keys in the hierarchical data nodes shall consist of the name of the node,
-"@" character and the number of the node in hexadecimal notation (without pre-
-or postfixes). The same ACPI object shall include the _DSD property extension
-with a property "reg" that shall have the same numerical value as the number of
-the node.
-
-In case a hierarchical data extensions node has no numerical value, then the
-"reg" property shall be omitted from the ACPI object's _DSD properties and the
-"@" character and the number shall be omitted from the hierarchical data
-extension key.
-
-
-Example
--------
-
-	In the ASL snippet below, the "reference" _DSD property [2] contains a
-	device object reference to DEV0 and under that device object, a
-	hierarchical data extension key "node@1" referring to the NOD1 object
-	and lastly, a hierarchical data extension key "anothernode" referring to
-	the ANOD object which is also the final target node of the reference.
-
-	Device (DEV0)
-	{
-	    Name (_DSD, Package () {
-		ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"),

-_DSD
-----
-
-_DSD (Device Specific Data) [7] is a predefined ACPI device
-configuration object that can be used to convey information on
-hardware features which are not specifically covered by the ACPI
-specification [1][6]. There are two _DSD extensions that are relevant
-for graphs: property [4] and hierarchical data extensions [5]. The
-property extension provides generic key-value pairs whereas the
-hierarchical data extension supports nodes with references to other
-nodes, forming a tree. The nodes in the tree may contain properties as
-defined by the property extension. The two extensions together provide
-a tree-like structure with zero or more properties (key-value pairs)
-in each node of the tree.
-
-The data structure may be accessed at runtime by using the device_*
-and fwnode_* functions defined in include/linux/fwnode.h .
-
-Fwnode represents a generic firmware node object. It is independent on
-the firmware type. In ACPI, fwnodes are _DSD hierarchical data
-extensions objects. A device's _DSD object is represented by an
-fwnode.
-
-The data structure may be referenced to elsewhere in the ACPI tables
-by using a hard reference to the device itself and an index to the
-hierarchical data extension array on each depth.
-
-
-Ports and endpoints
--------------------
-
-The port and endpoint concepts are very similar to those in Devicetree
-[3]. A port represents an interface in a device, and an endpoint
-represents a connection to that interface.
-
-All port nodes are located under the device's "_DSD" node in the hierarchical
-data extension tree. The data extension related to each port node must begin
-with "port" and must be followed by the "@" character and the number of the port
-as its key. The target object it refers to should be called "PRTX", where "X" is
-the number of the port. An example of such a package would be:
-
-    Package() { "port@4", PRT4 }
-
-Further on, endpoints are located under the port nodes. The hierarchical
-data extension key of the endpoint nodes must begin with
-"endpoint" and must be followed by the "@" character and the number of the
-endpoint. The object it refers to should be called "EPXY", where "X" is the
-number of the port and "Y" is the number of the endpoint. An example of such a
-package would be:
-
-    Package() { "endpoint@0", EP40 }
-
-Each port node contains a property extension key "port", the value of which is
-the number of the port. Each endpoint is similarly numbered with a property
-extension key "reg", the value of which is the number of the endpoint. Port
-numbers must be unique within a device and endpoint numbers must be unique
-within a port. If a device object may only has a single port, then the number
-of that port shall be zero. Similarly, if a port may only have a single
-endpoint, the number of that endpoint shall be zero.
-
-The endpoint reference uses property extension with "remote-endpoint" property
-name followed by a reference in the same package. Such references consist of the
-the remote device reference, the first package entry of the port data extension
-reference under the device and finally the first package entry of the endpoint
-data extension reference under the port. Individual references thus appear as:
-
-    Package() { device, "port@X", "endpoint@Y" }
-
-In the above example, "X" is the number of the port and "Y" is the number of the
-endpoint.
-
-The references to endpoints must be always done both ways, to the
-remote endpoint and back from the referred remote endpoint node.
-
-A simple example of this is show below:
-
-    Scope (\_SB.PCI0.I2C2)
-    {
-	Device (CAM0)
-	{
-	    Name (_DSD, Package () {
-		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),

-		},
-		ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"),
-		Package () {
-		    Package () { "port@0", PRT0 },
-		}
-	    })
-	    Name (PRT0, Package() {
-		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
-		Package () {
-		    Package () { "reg", 0 },
-		},

-		}
-	    })

-		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
-		Package () {
-		    Package () { "reg", 0 },
-		    Package () { "remote-endpoint", Package() { \_SB.PCI0.ISP, "port@4", "endpoint@0" } },
-		}
-	    })
-	}
-    }
-
-    Scope (\_SB.PCI0)
-    {
-	Device (ISP)
-	{
-	    Name (_DSD, Package () {
-		ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"),
-		Package () {
-		    Package () { "port@4", PRT4 },
-		}
-	    })
-
-	    Name (PRT4, Package() {
-		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
-		Package () {
-		    Package () { "reg", 4 }, /* CSI-2 port number */
-		},

-		    Package () { "endpoint@0", EP40 },
-		}
-	    })

-		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
-		Package () {
-		    Package () { "reg", 0 },
-		    Package () { "remote-endpoint", Package () { \_SB.PCI0.I2C2.CAM0, "port@0", "endpoint@0" } },
-		}
-	    })
-	}
-    }
-
-Here, the port 0 of the "CAM0" device is connected to the port 4 of
-the "ISP" device and vice versa.

+Describing and referring to LEDs in ACPI
+
+Individual LEDs are described by hierarchical data extension [6] nodes under the
+device node, the LED driver chip. The "reg" property in the LED specific nodes
+tells the numerical ID of each individual LED output to which the LEDs are
+connected. [3] The hierarchical data nodes are named "led@X", where X is the
+number of the LED output.
+
+Referring to LEDs in Device tree is documented in [4], in "flash-leds" property
+documentation. In short, LEDs are directly referred to by using phandles.
+
+While Device tree allows referring to any node in the tree[1], in ACPI
+references are limited to device nodes only [2]. For this reason using the same
+mechanism on ACPI is not possible. A mechanism to refer to non-device ACPI nodes
+is documented in [7].
+
+ACPI allows (as does DT) using integer arguments after the reference. A
+combination of the LED driver device reference and an integer argument,
+referring to the "reg" property of the relevant LED, is used to identify
+individual LEDs. The value of the "reg" property is a contract between the
+firmware and software, it uniquely identifies the LED driver outputs.
+
+Under the LED driver device, The first hierarchical data extension package list
+entry shall contain the string "led@" followed by the number of the LED,
+followed by the referred object name. That object shall be named "LED" followed
+by the number of the LED.

-_DSD Device Properties Usage Rules
-----------------------------------
-
-Properties, Property Sets and Property Subsets
-----------------------------------------------
-
-The _DSD (Device Specific Data) configuration object, introduced in ACPI 5.1,
-allows any type of device configuration data to be provided via the ACPI
-namespace.  In principle, the format of the data may be arbitrary, but it has to
-be identified by a UUID which must be recognized by the driver processing the
-_DSD output.  However, there are generic UUIDs defined for _DSD recognized by
-the ACPI subsystem in the Linux kernel which automatically processes the data
-packages associated with them and makes those data available to device drivers
-as "device properties".
-
-A device property is a data item consisting of a string key and a value (of a
-specific type) associated with it.
-
-In the ACPI _DSD context it is an element of the sub-package following the
-generic Device Properties UUID in the _DSD return package as specified in the
-Device Properties UUID definition document [1].
-
-It also may be regarded as the definition of a key and the associated data type
-that can be returned by _DSD in the Device Properties UUID sub-package for a
-given device.
-
-A property set is a collection of properties applicable to a hardware entity
-like a device.  In the ACPI _DSD context it is the set of all properties that
-can be returned in the Device Properties UUID sub-package for the device in
-question.
-
-Property subsets are nested collections of properties.  Each of them is
-associated with an additional key (name) allowing the subset to be referred
-to as a whole (and to be treated as a separate entity).  The canonical
-representation of property subsets is via the mechanism specified in the
-Hierarchical Properties Extension UUID definition document [2].
-
-Property sets may be hierarchical.  That is, a property set may contain
-multiple property subsets that each may contain property subsets of its
-own and so on.
-
-General Validity Rule for Property Sets
----------------------------------------
-
-Valid property sets must follow the guidance given by the Device Properties UUID
-definition document [1].
-
-_DSD properties are intended to be used in addition to, and not instead of, the
-existing mechanisms defined by the ACPI specification.  Therefore, as a rule,
-they should only be used if the ACPI specification does not make direct
-provisions for handling the underlying use case.  It generally is invalid to
-return property sets which do not follow that rule from _DSD in data packages
-associated with the Device Properties UUID.
-
-Additional Considerations
--------------------------
-
-There are cases in which, even if the general rule given above is followed in
-principle, the property set may still not be regarded as a valid one.
-
-For example, that applies to device properties which may cause kernel code
-(either a device driver or a library/subsystem) to access hardware in a way
-possibly leading to a conflict with AML methods in the ACPI namespace.  In
-particular, that may happen if the kernel code uses device properties to
-manipulate hardware normally controlled by ACPI methods related to power
-management, like _PSx and _DSW (for device objects) or _ON and _OFF (for power
-resource objects), or by ACPI device disabling/enabling methods, like _DIS and
-_SRS.
-
-In all cases in which kernel code may do something that will confuse AML as a
-result of using device properties, the device properties in question are not
-suitable for the ACPI environment and consequently they cannot belong to a valid
-property set.
-
-Property Sets and Device Tree Bindings
---------------------------------------
-
-It often is useful to make _DSD return property sets that follow Device Tree
-bindings.
-
-In those cases, however, the above validity considerations must be taken into
-account in the first place and returning invalid property sets from _DSD must be
-avoided.  For this reason, it may not be possible to make _DSD return a property
-set following the given DT binding literally and completely.  Still, for the
-sake of code re-use, it may make sense to provide as much of the configuration
-data as possible in the form of device properties and complement that with an
-ACPI-specific mechanism suitable for the use case at hand.
-
-In any case, property sets following DT bindings literally should not be
-expected to automatically work in the ACPI environment regardless of their
-contents.

-ACPI based device enumeration
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-ACPI 5 introduced a set of new resources (UartTSerialBus, I2cSerialBus,
-SpiSerialBus, GpioIo and GpioInt) which can be used in enumerating slave
-devices behind serial bus controllers.
-
-In addition we are starting to see peripherals integrated in the
-SoC/Chipset to appear only in ACPI namespace. These are typically devices
-that are accessed through memory-mapped registers.
-
-In order to support this and re-use the existing drivers as much as
-possible we decided to do following:
-
-	o Devices that have no bus connector resource are represented as
-	  platform devices.
-
-	o Devices behind real busses where there is a connector resource
-	  are represented as struct spi_device or struct i2c_device
-	  (standard UARTs are not busses so there is no struct uart_device).
-
-As both ACPI and Device Tree represent a tree of devices (and their
-resources) this implementation follows the Device Tree way as much as
-possible.
-
-The ACPI implementation enumerates devices behind busses (platform, SPI and
-I2C), creates the physical devices and binds them to their ACPI handle in
-the ACPI namespace.
-
-This means that when ACPI_HANDLE(dev) returns non-NULL the device was
-enumerated from ACPI namespace. This handle can be used to extract other
-device-specific configuration. There is an example of this below.
-
-Platform bus support
-~~~~~~~~~~~~~~~~~~~~
-Since we are using platform devices to represent devices that are not
-connected to any physical bus we only need to implement a platform driver
-for the device and add supported ACPI IDs. If this same IP-block is used on
-some other non-ACPI platform, the driver might work out of the box or needs
-some minor changes.
-
-Adding ACPI support for an existing driver should be pretty
-straightforward. Here is the simplest example:
-
-	#ifdef CONFIG_ACPI
-	static const struct acpi_device_id mydrv_acpi_match[] = {
-		/* ACPI IDs here */
-		{ }
-	};
-	MODULE_DEVICE_TABLE(acpi, mydrv_acpi_match);
-	#endif
-
-	static struct platform_driver my_driver = {
-		...
-		.driver = {
-			.acpi_match_table = ACPI_PTR(mydrv_acpi_match),
-		},
-	};
-
-If the driver needs to perform more complex initialization like getting and
-configuring GPIOs it can get its ACPI handle and extract this information
-from ACPI tables.
-
-DMA support
-~~~~~~~~~~~
-DMA controllers enumerated via ACPI should be registered in the system to
-provide generic access to their resources. For example, a driver that would
-like to be accessible to slave devices via generic API call
-dma_request_slave_channel() must register itself at the end of the probe
-function like this:
-
-	err = devm_acpi_dma_controller_register(dev, xlate_func, dw);
-	/* Handle the error if it's not a case of !CONFIG_ACPI */
-
-and implement custom xlate function if needed (usually acpi_dma_simple_xlate()
-is enough) which converts the FixedDMA resource provided by struct
-acpi_dma_spec into the corresponding DMA channel. A piece of code for that case
-could look like:
-
-	#ifdef CONFIG_ACPI
-	struct filter_args {
-		/* Provide necessary information for the filter_func */
-		...
-	};
-
-	static bool filter_func(struct dma_chan *chan, void *param)
-	{
-		/* Choose the proper channel */
-		...
-	}
-
-	static struct dma_chan *xlate_func(struct acpi_dma_spec *dma_spec,
-			struct acpi_dma *adma)
-	{
-		dma_cap_mask_t cap;
-		struct filter_args args;
-
-		/* Prepare arguments for filter_func */
-		...
-		return dma_request_channel(cap, filter_func, &args);
-	}
-	#else
-	static struct dma_chan *xlate_func(struct acpi_dma_spec *dma_spec,
-			struct acpi_dma *adma)
-	{
-		return NULL;
-	}
-	#endif
-
-dma_request_slave_channel() will call xlate_func() for each registered DMA
-controller. In the xlate function the proper channel must be chosen based on
-information in struct acpi_dma_spec and the properties of the controller
-provided by struct acpi_dma.
-
-Clients must call dma_request_slave_channel() with the string parameter that
-corresponds to a specific FixedDMA resource. By default "tx" means the first
-entry of the FixedDMA resource array, "rx" means the second entry. The table
-below shows a layout:
-
-	Device (I2C0)
-	{
-		...
-		Method (_CRS, 0, NotSerialized)
-		{
-			Name (DBUF, ResourceTemplate ()
-			{
-				FixedDMA (0x0018, 0x0004, Width32bit, _Y48)
-				FixedDMA (0x0019, 0x0005, Width32bit, )
-			})
-		...
-		}
-	}
-
-So, the FixedDMA with request line 0x0018 is "tx" and next one is "rx" in
-this example.
-
-In robust cases the client unfortunately needs to call
-acpi_dma_request_slave_chan_by_index() directly and therefore choose the
-specific FixedDMA resource by its index.
-
-SPI serial bus support
-~~~~~~~~~~~~~~~~~~~~~~
-Slave devices behind SPI bus have SpiSerialBus resource attached to them.
-This is extracted automatically by the SPI core and the slave devices are
-enumerated once spi_register_master() is called by the bus driver.
-
-Here is what the ACPI namespace for a SPI slave might look like:
-
-	Device (EEP0)
-	{
-		Name (_ADR, 1)
-		Name (_CID, Package() {
-			"ATML0025",
-			"AT25",
-		})
-		...
-		Method (_CRS, 0, NotSerialized)
-		{
-			SPISerialBus(1, PolarityLow, FourWireMode, 8,
-				ControllerInitiated, 1000000, ClockPolarityLow,
-				ClockPhaseFirst, "\\_SB.PCI0.SPI1",)
-		}
-		...
-
-The SPI device drivers only need to add ACPI IDs in a similar way than with
-the platform device drivers. Below is an example where we add ACPI support
-to at25 SPI eeprom driver (this is meant for the above ACPI snippet):
-
-	#ifdef CONFIG_ACPI
-	static const struct acpi_device_id at25_acpi_match[] = {
-		{ "AT25", 0 },
-		{ },
-	};
-	MODULE_DEVICE_TABLE(acpi, at25_acpi_match);
-	#endif
-
-	static struct spi_driver at25_driver = {
-		.driver = {
-			...
-			.acpi_match_table = ACPI_PTR(at25_acpi_match),
-		},
-	};
-
-Note that this driver actually needs more information like page size of the
-eeprom etc. but at the time writing this there is no standard way of
-passing those. One idea is to return this in _DSM method like:
-
-	Device (EEP0)
-	{
-		...
-		Method (_DSM, 4, NotSerialized)
-		{
-			Store (Package (6)
-			{
-				"byte-len", 1024,
-				"addr-mode", 2,
-				"page-size, 32
-			}, Local0)
-
-			// Check UUIDs etc.
-
-			Return (Local0)
-		}
-
-Then the at25 SPI driver can get this configuration by calling _DSM on its
-ACPI handle like:
-
-	struct acpi_buffer output = { ACPI_ALLOCATE_BUFFER, NULL };
-	struct acpi_object_list input;
-	acpi_status status;
-
-	/* Fill in the input buffer */
-
-	status = acpi_evaluate_object(ACPI_HANDLE(&spi->dev), "_DSM",
-				      &input, &output);
-	if (ACPI_FAILURE(status))
-		/* Handle the error */
-
-	/* Extract the data here */
-
-	kfree(output.pointer);
-
-I2C serial bus support
-~~~~~~~~~~~~~~~~~~~~~~
-The slaves behind I2C bus controller only need to add the ACPI IDs like
-with the platform and SPI drivers. The I2C core automatically enumerates
-any slave devices behind the controller device once the adapter is
-registered.
-
-Below is an example of how to add ACPI support to the existing mpu3050
-input driver:
-
-	#ifdef CONFIG_ACPI
-	static const struct acpi_device_id mpu3050_acpi_match[] = {
-		{ "MPU3050", 0 },
-		{ },
-	};
-	MODULE_DEVICE_TABLE(acpi, mpu3050_acpi_match);
-	#endif
-
-	static struct i2c_driver mpu3050_i2c_driver = {
-		.driver	= {
-			.name	= "mpu3050",
-			.owner	= THIS_MODULE,
-			.pm	= &mpu3050_pm,
-			.of_match_table = mpu3050_of_match,
-			.acpi_match_table = ACPI_PTR(mpu3050_acpi_match),
-		},
-		.probe		= mpu3050_probe,
-		.remove		= mpu3050_remove,
-		.id_table	= mpu3050_ids,
-	};
-
-GPIO support
-~~~~~~~~~~~~
-ACPI 5 introduced two new resources to describe GPIO connections: GpioIo
-and GpioInt. These resources can be used to pass GPIO numbers used by
-the device to the driver. ACPI 5.1 extended this with _DSD (Device
-Specific Data) which made it possible to name the GPIOs among other things.
-
-For example:
-
-Device (DEV)
-{
-	Method (_CRS, 0, NotSerialized)
-	{
-		Name (SBUF, ResourceTemplate()
-		{
-			...
-			// Used to power on/off the device
-			GpioIo (Exclusive, PullDefault, 0x0000, 0x0000,
-				IoRestrictionOutputOnly, "\\_SB.PCI0.GPI0",
-				0x00, ResourceConsumer,,)
-			{
-				// Pin List
-				0x0055
-			}
-
-			// Interrupt for the device
-			GpioInt (Edge, ActiveHigh, ExclusiveAndWake, PullNone,
-				 0x0000, "\\_SB.PCI0.GPI0", 0x00, ResourceConsumer,,)
-			{
-				// Pin list
-				0x0058
-			}
-
-			...
-
-		}
-
-		Return (SBUF)
-	}
-
-	// ACPI 5.1 _DSD used for naming the GPIOs
-	Name (_DSD, Package ()
-	{
-		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
-		Package ()
-		{
-			Package () {"power-gpios", Package() {^DEV, 0, 0, 0 }},
-			Package () {"irq-gpios", Package() {^DEV, 1, 0, 0 }},
-		}
-	})
-	...
-
-These GPIO numbers are controller relative and path "\\_SB.PCI0.GPI0"
-specifies the path to the controller. In order to use these GPIOs in Linux
-we need to translate them to the corresponding Linux GPIO descriptors.
-
-There is a standard GPIO API for that and is documented in
-Documentation/gpio/.
-
-In the above example we can get the corresponding two GPIO descriptors with
-a code like this:
-
-	#include <linux/gpio/consumer.h>
-	...
-
-	struct gpio_desc *irq_desc, *power_desc;
-
-	irq_desc = gpiod_get(dev, "irq");
-	if (IS_ERR(irq_desc))
-		/* handle error */
-
-	power_desc = gpiod_get(dev, "power");
-	if (IS_ERR(power_desc))
-		/* handle error */
-
-	/* Now we can use the GPIO descriptors */
-
-There are also devm_* versions of these functions which release the
-descriptors once the device is released.
-
-See Documentation/acpi/gpio-properties.txt for more information about the
-_DSD binding related to GPIOs.
-
-MFD devices
-~~~~~~~~~~~
-The MFD devices register their children as platform devices. For the child
-devices there needs to be an ACPI handle that they can use to reference
-parts of the ACPI namespace that relate to them. In the Linux MFD subsystem
-we provide two ways:
-
-	o The children share the parent ACPI handle.
-	o The MFD cell can specify the ACPI id of the device.
-
-For the first case, the MFD drivers do not need to do anything. The
-resulting child platform device will have its ACPI_COMPANION() set to point
-to the parent device.
-
-If the ACPI namespace has a device that we can match using an ACPI id or ACPI
-adr, the cell should be set like:
-
-	static struct mfd_cell_acpi_match my_subdevice_cell_acpi_match = {
-		.pnpid = "XYZ0001",
-		.adr = 0,
-	};
-
-	static struct mfd_cell my_subdevice_cell = {
-		.name = "my_subdevice",
-		/* set the resources relative to the parent */
-		.acpi_match = &my_subdevice_cell_acpi_match,
-	};
-
-The ACPI id "XYZ0001" is then used to lookup an ACPI device directly under
-the MFD device and if found, that ACPI companion device is bound to the
-resulting child platform device.
-
-Device Tree namespace link device ID
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The Device Tree protocol uses device identification based on the "compatible"
-property whose value is a string or an array of strings recognized as device
-identifiers by drivers and the driver core.  The set of all those strings may be
-regarded as a device identification namespace analogous to the ACPI/PNP device
-ID namespace.  Consequently, in principle it should not be necessary to allocate
-a new (and arguably redundant) ACPI/PNP device ID for a devices with an existing
-identification string in the Device Tree (DT) namespace, especially if that ID
-is only needed to indicate that a given device is compatible with another one,
-presumably having a matching driver in the kernel already.
-
-In ACPI, the device identification object called _CID (Compatible ID) is used to
-list the IDs of devices the given one is compatible with, but those IDs must
-belong to one of the namespaces prescribed by the ACPI specification (see
-Section 6.1.2 of ACPI 6.0 for details) and the DT namespace is not one of them.
-Moreover, the specification mandates that either a _HID or an _ADR identification
-object be present for all ACPI objects representing devices (Section 6.1 of ACPI
-6.0).  For non-enumerable bus types that object must be _HID and its value must
-be a device ID from one of the namespaces prescribed by the specification too.
-
-The special DT namespace link device ID, PRP0001, provides a means to use the
-existing DT-compatible device identification in ACPI and to satisfy the above
-requirements following from the ACPI specification at the same time.  Namely,
-if PRP0001 is returned by _HID, the ACPI subsystem will look for the
-"compatible" property in the device object's _DSD and will use the value of that
-property to identify the corresponding device in analogy with the original DT
-device identification algorithm.  If the "compatible" property is not present
-or its value is not valid, the device will not be enumerated by the ACPI
-subsystem.  Otherwise, it will be enumerated automatically as a platform device
-(except when an I2C or SPI link from the device to its parent is present, in
-which case the ACPI core will leave the device enumeration to the parent's
-driver) and the identification strings from the "compatible" property value will
-be used to find a driver for the device along with the device IDs listed by _CID
-(if present).
-
-Analogously, if PRP0001 is present in the list of device IDs returned by _CID,
-the identification strings listed by the "compatible" property value (if present
-and valid) will be used to look for a driver matching the device, but in that
-case their relative priority with respect to the other device IDs listed by
-_HID and _CID depends on the position of PRP0001 in the _CID return package.
-Specifically, the device IDs returned by _HID and preceding PRP0001 in the _CID
-return package will be checked first.  Also in that case the bus type the device
-will be enumerated to depends on the device ID returned by _HID.
-
-It is valid to define device objects with a _HID returning PRP0001 and without
-the "compatible" property in the _DSD or a _CID as long as one of their
-ancestors provides a _DSD with a valid "compatible" property.  Such device
-objects are then simply regarded as additional "blocks" providing hierarchical
-configuration information to the driver of the composite ancestor device.
-
-However, PRP0001 can only be returned from either _HID or _CID of a device
-object if all of the properties returned by the _DSD associated with it (either
-the _DSD of the device object itself or the _DSD of its ancestor in the
-"composite device" case described above) can be used in the ACPI environment.
-Otherwise, the _DSD itself is regarded as invalid and therefore the "compatible"
-property returned by it is meaningless.
-
-Refer to DSD-properties-rules.txt for more information.

-_DSD Device Properties Related to GPIO
---------------------------------------
-
-With the release of ACPI 5.1, the _DSD configuration object finally
-allows names to be given to GPIOs (and other things as well) returned
-by _CRS.  Previously, we were only able to use an integer index to find
-the corresponding GPIO, which is pretty error prone (it depends on
-the _CRS output ordering, for example).
-
-With _DSD we can now query GPIOs using a name instead of an integer
-index, like the ASL example below shows:
-
-  // Bluetooth device with reset and shutdown GPIOs
-  Device (BTH)
-  {
-      Name (_HID, ...)
-
-      Name (_CRS, ResourceTemplate ()
-      {
-          GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
-                  "\\_SB.GPO0", 0, ResourceConsumer) {15}
-          GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
-                  "\\_SB.GPO0", 0, ResourceConsumer) {27, 31}
-      })
-
-      Name (_DSD, Package ()
-      {
-          ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
-          Package ()
-	  {
-              Package () {"reset-gpios", Package() {^BTH, 1, 1, 0 }},
-              Package () {"shutdown-gpios", Package() {^BTH, 0, 0, 0 }},
-          }
-      })
-  }
-
-The format of the supported GPIO property is:
-
-  Package () { "name", Package () { ref, index, pin, active_low }}
-
-  ref - The device that has _CRS containing GpioIo()/GpioInt() resources,
-        typically this is the device itself (BTH in our case).
-  index - Index of the GpioIo()/GpioInt() resource in _CRS starting from zero.
-  pin - Pin in the GpioIo()/GpioInt() resource. Typically this is zero.
-  active_low - If 1 the GPIO is marked as active_low.
-
-Since ACPI GpioIo() resource does not have a field saying whether it is
-active low or high, the "active_low" argument can be used here.  Setting
-it to 1 marks the GPIO as active low.
-
-In our Bluetooth example the "reset-gpios" refers to the second GpioIo()
-resource, second pin in that resource with the GPIO number of 31.
-
-It is possible to leave holes in the array of GPIOs. This is useful in
-cases like with SPI host controllers where some chip selects may be
-implemented as GPIOs and some as native signals. For example a SPI host
-controller can have chip selects 0 and 2 implemented as GPIOs and 1 as
-native:
-
-  Package () {
-      "cs-gpios",
-      Package () {
-          ^GPIO, 19, 0, 0, // chip select 0: GPIO
-          0,               // chip select 1: native signal
-          ^GPIO, 20, 0, 0, // chip select 2: GPIO
-      }
-  }
-
-Other supported properties
---------------------------
-
-Following Device Tree compatible device properties are also supported by
-_DSD device properties for GPIO controllers:
-
-- gpio-hog
-- output-high
-- output-low
-- input
-- line-name
-
-Example:
-
-  Name (_DSD, Package () {
-      // _DSD Hierarchical Properties Extension UUID
-      ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"),
-      Package () {
-          Package () {"hog-gpio8", "G8PU"}
-      }
-  })
-
-  Name (G8PU, Package () {
-      ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
-      Package () {
-          Package () {"gpio-hog", 1},
-          Package () {"gpios", Package () {8, 0}},
-          Package () {"output-high", 1},
-          Package () {"line-name", "gpio8-pullup"},
-      }
-  })
-
-- gpio-line-names
-
-Example:
-
-  Package () {
-      "gpio-line-names",
-      Package () {
-          "SPI0_CS_N", "EXP2_INT", "MUX6_IO", "UART0_RXD", "MUX7_IO",
-          "LVL_C_A1", "MUX0_IO", "SPI1_MISO"
-      }
-  }
-
-See Documentation/devicetree/bindings/gpio/gpio.txt for more information
-about these properties.
-
-ACPI GPIO Mappings Provided by Drivers
---------------------------------------
-
-There are systems in which the ACPI tables do not contain _DSD but provide _CRS
-with GpioIo()/GpioInt() resources and device drivers still need to work with
-them.
-
-In those cases ACPI device identification objects, _HID, _CID, _CLS, _SUB, _HRV,
-available to the driver can be used to identify the device and that is supposed
-to be sufficient to determine the meaning and purpose of all of the GPIO lines
-listed by the GpioIo()/GpioInt() resources returned by _CRS.  In other words,
-the driver is supposed to know what to use the GpioIo()/GpioInt() resources for
-once it has identified the device.  Having done that, it can simply assign names
-to the GPIO lines it is going to use and provide the GPIO subsystem with a
-mapping between those names and the ACPI GPIO resources corresponding to them.
-
-To do that, the driver needs to define a mapping table as a NULL-terminated
-array of struct acpi_gpio_mapping objects that each contain a name, a pointer
-to an array of line data (struct acpi_gpio_params) objects and the size of that
-array.  Each struct acpi_gpio_params object consists of three fields,
-crs_entry_index, line_index, active_low, representing the index of the target
-GpioIo()/GpioInt() resource in _CRS starting from zero, the index of the target
-line in that resource starting from zero, and the active-low flag for that line,
-respectively, in analogy with the _DSD GPIO property format specified above.
-
-For the example Bluetooth device discussed previously the data structures in
-question would look like this:
-
-static const struct acpi_gpio_params reset_gpio = { 1, 1, false };
-static const struct acpi_gpio_params shutdown_gpio = { 0, 0, false };
-
-static const struct acpi_gpio_mapping bluetooth_acpi_gpios[] = {
-  { "reset-gpios", &reset_gpio, 1 },
-  { "shutdown-gpios", &shutdown_gpio, 1 },
-  { },
-};
-
-Next, the mapping table needs to be passed as the second argument to
-acpi_dev_add_driver_gpios() that will register it with the ACPI device object
-pointed to by its first argument.  That should be done in the driver's .probe()
-routine.  On removal, the driver should unregister its GPIO mapping table by
-calling acpi_dev_remove_driver_gpios() on the ACPI device object where that
-table was previously registered.
-
-Using the _CRS fallback
------------------------
-
-If a device does not have _DSD or the driver does not create ACPI GPIO
-mapping, the Linux GPIO framework refuses to return any GPIOs. This is
-because the driver does not know what it actually gets. For example if we
-have a device like below:
-
-  Device (BTH)
-  {
-      Name (_HID, ...)

-          GpioIo (Exclusive, PullNone, 0, 0, IoRestrictionNone,

-          GpioIo (Exclusive, PullNone, 0, 0, IoRestrictionNone,

-The driver might expect to get the right GPIO when it does:
-
-  desc = gpiod_get(dev, "reset", GPIOD_OUT_LOW);
-
-but since there is no way to know the mapping between "reset" and
-the GpioIo() in _CRS desc will hold ERR_PTR(-ENOENT).
-
-The driver author can solve this by passing the mapping explictly
-(the recommended way and documented in the above chapter).
-
-The ACPI GPIO mapping tables should not contaminate drivers that are not
-knowing about which exact device they are servicing on. It implies that
-the ACPI GPIO mapping tables are hardly linked to ACPI ID and certain
-objects, as listed in the above chapter, of the device in question.
-
-Getting GPIO descriptor
------------------------
-
-There are two main approaches to get GPIO resource from ACPI:
-	desc = gpiod_get(dev, connection_id, flags);
-	desc = gpiod_get_index(dev, connection_id, index, flags);
-
-We may consider two different cases here, i.e. when connection ID is
-provided and otherwise.
-
-Case 1:
-	desc = gpiod_get(dev, "non-null-connection-id", flags);
-	desc = gpiod_get_index(dev, "non-null-connection-id", index, flags);
-
-Case 2:
-	desc = gpiod_get(dev, NULL, flags);
-	desc = gpiod_get_index(dev, NULL, index, flags);
-
-Case 1 assumes that corresponding ACPI device description must have
-defined device properties and will prevent to getting any GPIO resources
-otherwise.
-
-Case 2 explicitly tells GPIO core to look for resources in _CRS.
-
-Be aware that gpiod_get_index() in cases 1 and 2, assuming that there
-are two versions of ACPI device description provided and no mapping is
-present in the driver, will return different resources. That's why a
-certain driver has to handle them carefully as explained in previous
-chapter.

-Upgrading ACPI tables via initrd
-================================
-
-1) Introduction (What is this about)
-2) What is this for
-3) How does it work
-4) References (Where to retrieve userspace tools)
-
-1) What is this about
----------------------
-
-If the ACPI_TABLE_UPGRADE compile option is true, it is possible to
-upgrade the ACPI execution environment that is defined by the ACPI tables
-via upgrading the ACPI tables provided by the BIOS with an instrumented,
-modified, more recent version one, or installing brand new ACPI tables.
-
-When building initrd with kernel in a single image, option
-ACPI_TABLE_OVERRIDE_VIA_BUILTIN_INITRD should also be true for this
-feature to work.
-
-For a full list of ACPI tables that can be upgraded/installed, take a look
-at the char *table_sigs[MAX_ACPI_SIGNATURE]; definition in
-drivers/acpi/tables.c.
-All ACPI tables iasl (Intel's ACPI compiler and disassembler) knows should
-be overridable, except:
-   - ACPI_SIG_RSDP (has a signature of 6 bytes)
-   - ACPI_SIG_FACS (does not have an ordinary ACPI table header)
-Both could get implemented as well.
-
-
-2) What is this for
--------------------
-
-Complain to your platform/BIOS vendor if you find a bug which is so severe
-that a workaround is not accepted in the Linux kernel. And this facility
-allows you to upgrade the buggy tables before your platform/BIOS vendor
-releases an upgraded BIOS binary.
-
-This facility can be used by platform/BIOS vendors to provide a Linux
-compatible environment without modifying the underlying platform firmware.
-
-This facility also provides a powerful feature to easily debug and test
-ACPI BIOS table compatibility with the Linux kernel by modifying old
-platform provided ACPI tables or inserting new ACPI tables.
-
-It can and should be enabled in any kernel because there is no functional
-change with not instrumented initrds.
-
-
-3) How does it work
--------------------
-
-# Extract the machine's ACPI tables:
-cd /tmp
-acpidump >acpidump
-acpixtract -a acpidump
-# Disassemble, modify and recompile them:
-iasl -d *.dat
-# For example add this statement into a _PRT (PCI Routing Table) function
-# of the DSDT:
-Store("HELLO WORLD", debug)
-# And increase the OEM Revision. For example, before modification:
-DefinitionBlock ("DSDT.aml", "DSDT", 2, "INTEL ", "TEMPLATE", 0x00000000)
-# After modification:
-DefinitionBlock ("DSDT.aml", "DSDT", 2, "INTEL ", "TEMPLATE", 0x00000001)
-iasl -sa dsdt.dsl
-# Add the raw ACPI tables to an uncompressed cpio archive.
-# They must be put into a /kernel/firmware/acpi directory inside the cpio
-# archive. Note that if the table put here matches a platform table
-# (similar Table Signature, and similar OEMID, and similar OEM Table ID)
-# with a more recent OEM Revision, the platform table will be upgraded by
-# this table. If the table put here doesn't match a platform table
-# (dissimilar Table Signature, or dissimilar OEMID, or dissimilar OEM Table
-# ID), this table will be appended.
-mkdir -p kernel/firmware/acpi
-cp dsdt.aml kernel/firmware/acpi
-# A maximum of "NR_ACPI_INITRD_TABLES (64)" tables are currently allowed
-# (see osl.c):
-iasl -sa facp.dsl
-iasl -sa ssdt1.dsl
-cp facp.aml kernel/firmware/acpi
-cp ssdt1.aml kernel/firmware/acpi
-# The uncompressed cpio archive must be the first. Other, typically
-# compressed cpio archives, must be concatenated on top of the uncompressed
-# one. Following command creates the uncompressed cpio archive and
-# concatenates the original initrd on top:
-find kernel | cpio -H newc --create > /boot/instrumented_initrd
-cat /boot/initrd >>/boot/instrumented_initrd
-# reboot with increased acpi debug level, e.g. boot params:
-acpi.debug_level=0x2 acpi.debug_layer=0xFFFFFFFF
-# and check your syslog:
-[    1.268089] ACPI: PCI Interrupt Routing Table [\_SB_.PCI0._PRT]
-[    1.272091] [ACPI Debug]  String [0x0B] "HELLO WORLD"
-
-iasl is able to disassemble and recompile quite a lot different,
-also static ACPI tables.
-
-
-4) Where to retrieve userspace tools
-------------------------------------
-
-iasl and acpixtract are part of Intel's ACPICA project:
-http://acpica.org/
-and should be packaged by distributions (for example in the acpica package
-on SUSE).
-
-acpidump can be found in Len Browns pmtools:
-ftp://kernel.org/pub/linux/kernel/people/lenb/acpi/utils/pmtools/acpidump
-This tool is also part of the acpica package on SUSE.
-Alternatively, used ACPI tables can be retrieved via sysfs in latest kernels:
-/sys/firmware/acpi/tables

-
-
-Abstract:
-
-This document describes the ACPICA project and the relationship between
-ACPICA and Linux.  It also describes how ACPICA code in drivers/acpi/acpica,
-include/acpi and tools/power/acpi is automatically updated to follow the
-upstream.
-
-
-1. ACPICA Project
-
-   The ACPI Component Architecture (ACPICA) project provides an operating
-   system (OS)-independent reference implementation of the Advanced
-   Configuration and Power Interface Specification (ACPI).  It has been
-   adapted by various host OSes.  By directly integrating ACPICA, Linux can
-   also benefit from the application experiences of ACPICA from other host
-   OSes.
-
-   The homepage of ACPICA project is: www.acpica.org, it is maintained and
-   supported by Intel Corporation.
-
-   The following figure depicts the Linux ACPI subsystem where the ACPICA
-   adaptation is included:

-2. ACPICA Release
-
-   The ACPICA project maintains its code base at the following repository URL:
-   https://github.com/acpica/acpica.git. As a rule, a release is made every
-   month.
-
-   As the coding style adopted by the ACPICA project is not acceptable by
-   Linux, there is a release process to convert the ACPICA git commits into
-   Linux patches.  The patches generated by this process are referred to as
-   "linuxized ACPICA patches".  The release process is carried out on a local
-   copy the ACPICA git repository.  Each commit in the monthly release is
-   converted into a linuxized ACPICA patch.  Together, they form the monthly
-   ACPICA release patchset for the Linux ACPI community.  This process is
-   illustrated in the following figure:
-

-
-   NOTE:
-    A. Linuxize Utilities - Provided by the ACPICA repository, including a
-       utility located in source/tools/acpisrc folder and a number of
-       scripts located in generate/linux folder.
-    B. acpica / master - "master" branch of the git repository at
-       <https://github.com/acpica/acpica.git>.
-    C. linux-pm / linux-next - "linux-next" branch of the git repository at
-       <http://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git>.
-    D. linux / master - "master" branch of the git repository at
-       <http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git>.
-
-   Before the linuxized ACPICA patches are sent to the Linux ACPI community
-   for review, there is a quality assurance build test process to reduce
-   porting issues.  Currently this build process only takes care of the
-   following kernel configuration options:
-   CONFIG_ACPI/CONFIG_ACPI_DEBUG/CONFIG_ACPI_DEBUGGER
-
-3. ACPICA Divergences
-
-   Ideally, all of the ACPICA commits should be converted into Linux patches
-   automatically without manual modifications, the "linux / master" tree should
-   contain the ACPICA code that exactly corresponds to the ACPICA code
-   contained in "new linuxized acpica" tree and it should be possible to run
-   the release process fully automatically.
-
-   As a matter of fact, however, there are source code differences between
-   the ACPICA code in Linux and the upstream ACPICA code, referred to as
-   "ACPICA Divergences".
-
-   The various sources of ACPICA divergences include:
-   1. Legacy divergences - Before the current ACPICA release process was
-      established, there already had been divergences between Linux and
-      ACPICA. Over the past several years those divergences have been greatly
-      reduced, but there still are several ones and it takes time to figure
-      out the underlying reasons for their existence.
-   2. Manual modifications - Any manual modification (eg. coding style fixes)
-      made directly in the Linux sources obviously hurts the ACPICA release
-      automation.  Thus it is recommended to fix such issues in the ACPICA
-      upstream source code and generate the linuxized fix using the ACPICA
-      release utilities (please refer to Section 4 below for the details).
-   3. Linux specific features - Sometimes it's impossible to use the
-      current ACPICA APIs to implement features required by the Linux kernel,
-      so Linux developers occasionally have to change ACPICA code directly.
-      Those changes may not be acceptable by ACPICA upstream and in such cases
-      they are left as committed ACPICA divergences unless the ACPICA side can
-      implement new mechanisms as replacements for them.
-   4. ACPICA release fixups - ACPICA only tests commits using a set of the
-      user space simulation utilities, thus the linuxized ACPICA patches may
-      break the Linux kernel, leaving us build/boot failures.  In order to
-      avoid breaking Linux bisection, fixes are applied directly to the
-      linuxized ACPICA patches during the release process.  When the release
-      fixups are backported to the upstream ACPICA sources, they must follow
-      the upstream ACPICA rules and so further modifications may appear.
-      That may result in the appearance of new divergences.
-   5. Fast tracking of ACPICA commits - Some ACPICA commits are regression
-      fixes or stable-candidate material, so they are applied in advance with
-      respect to the ACPICA release process.  If such commits are reverted or
-      rebased on the ACPICA side in order to offer better solutions, new ACPICA
-      divergences are generated.
-
-4. ACPICA Development
-
-   This paragraph guides Linux developers to use the ACPICA upstream release
-   utilities to obtain Linux patches corresponding to upstream ACPICA commits
-   before they become available from the ACPICA release process.
-
-   1. Cherry-pick an ACPICA commit
-
-   First you need to git clone the ACPICA repository and the ACPICA change
-   you want to cherry pick must be committed into the local repository.
-
-   Then the gen-patch.sh command can help to cherry-pick an ACPICA commit
-   from the ACPICA local repository:
-
-   $ git clone https://github.com/acpica/acpica
-   $ cd acpica
-   $ generate/linux/gen-patch.sh -u [commit ID]
-
-   Here the commit ID is the ACPICA local repository commit ID you want to
-   cherry pick.  It can be omitted if the commit is "HEAD".
-
-   2. Cherry-pick recent ACPICA commits
-
-   Sometimes you need to rebase your code on top of the most recent ACPICA
-   changes that haven't been applied to Linux yet.
-
-   You can generate the ACPICA release series yourself and rebase your code on
-   top of the generated ACPICA release patches:
-
-   $ git clone https://github.com/acpica/acpica
-   $ cd acpica
-   $ generate/linux/make-patches.sh -u [commit ID]
-
-   The commit ID should be the last ACPICA commit accepted by Linux.  Usually,
-   it is the commit modifying ACPI_CA_VERSION.  It can be found by executing
-   "git blame source/include/acpixf.h" and referencing the line that contains
-   "ACPI_CA_VERSION".
-
-   3. Inspect the current divergences
-
-   If you have local copies of both Linux and upstream ACPICA, you can generate
-   a diff file indicating the state of the current divergences:
-
-   # git clone https://github.com/acpica/acpica
-   # git clone http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
-   # cd acpica
-   # generate/linux/divergences.sh -s ../linux

-Linux ACPI Custom Control Method How To
-=======================================
-
-Written by Zhang Rui <rui.zhang@intel.com>
-
-
-Linux supports customizing ACPI control methods at runtime.
-
-Users can use this to
-1. override an existing method which may not work correctly,
-   or just for debugging purposes.
-2. insert a completely new method in order to create a missing
-   method such as _OFF, _ON, _STA, _INI, etc.
-For these cases, it is far simpler to dynamically install a single
-control method rather than override the entire DSDT, because kernel
-rebuild/reboot is not needed and test result can be got in minutes.
-
-Note: Only ACPI METHOD can be overridden, any other object types like
-      "Device", "OperationRegion", are not recognized. Methods
-      declared inside scope operators are also not supported.
-Note: The same ACPI control method can be overridden for many times,
-      and it's always the latest one that used by Linux/kernel.
-Note: To get the ACPI debug object output (Store (AAAA, Debug)),
-      please run "echo 1 > /sys/module/acpi/parameters/aml_debug_output".
-
-1. override an existing method
-   a) get the ACPI table via ACPI sysfs I/F. e.g. to get the DSDT,
-      just run "cat /sys/firmware/acpi/tables/DSDT > /tmp/dsdt.dat"
-   b) disassemble the table by running "iasl -d dsdt.dat".
-   c) rewrite the ASL code of the method and save it in a new file,
-   d) package the new file (psr.asl) to an ACPI table format.
-      Here is an example of a customized \_SB._AC._PSR method,
-
-      DefinitionBlock ("", "SSDT", 1, "", "", 0x20080715)
-      {
-	Method (\_SB_.AC._PSR, 0, NotSerialized)
-	{
-		Store ("In AC _PSR", Debug)
-		Return (ACON)
-	}
-      }
-      Note that the full pathname of the method in ACPI namespace
-      should be used.
-   e) assemble the file to generate the AML code of the method.
-      e.g. "iasl -vw 6084 psr.asl" (psr.aml is generated as a result)
-      If parameter "-vw 6084" is not supported by your iASL compiler,
-      please try a newer version.
-   f) mount debugfs by "mount -t debugfs none /sys/kernel/debug"
-   g) override the old method via the debugfs by running
-      "cat /tmp/psr.aml > /sys/kernel/debug/acpi/custom_method"
-
-2. insert a new method
-   This is easier than overriding an existing method.
-   We just need to create the ASL code of the method we want to
-   insert and then follow the step c) ~ g) in section 1.
-
-3. undo your changes
-   The "undo" operation is not supported for a new inserted method
-   right now, i.e. we can not remove a method currently.
-   For an overridden method, in order to undo your changes, please
-   save a copy of the method original ASL code in step c) section 1,
-   and redo step c) ~ g) to override the method with the original one.
-
-
-Note: We can use a kernel with multiple custom ACPI method running,
-      But each individual write to debugfs can implement a SINGLE
-      method override. i.e. if we want to insert/override multiple
-      ACPI methods, we need to redo step c) ~ g) for multiple times.
-
-Note: Be aware that root can mis-use this driver to modify arbitrary
-      memory and gain additional rights, if root's privileges got
-      restricted (for example if root is not allowed to load additional
-      modules after boot).

-ACPICA Trace Facility
-
-Copyright (C) 2015, Intel Corporation
-Author: Lv Zheng <lv.zheng@intel.com>
-
-
-Abstract:
-
-This document describes the functions and the interfaces of the method
-tracing facility.
-
-1. Functionalities and usage examples:
-
-   ACPICA provides method tracing capability. And two functions are
-   currently implemented using this capability.
-
-   A. Log reducer
-   ACPICA subsystem provides debugging outputs when CONFIG_ACPI_DEBUG is
-   enabled. The debugging messages which are deployed via
-   ACPI_DEBUG_PRINT() macro can be reduced at 2 levels - per-component
-   level (known as debug layer, configured via
-   /sys/module/acpi/parameters/debug_layer) and per-type level (known as
-   debug level, configured via /sys/module/acpi/parameters/debug_level).
-
-   But when the particular layer/level is applied to the control method
-   evaluations, the quantity of the debugging outputs may still be too
-   large to be put into the kernel log buffer. The idea thus is worked out
-   to only enable the particular debug layer/level (normally more detailed)
-   logs when the control method evaluation is started, and disable the
-   detailed logging when the control method evaluation is stopped.
-
-   The following command examples illustrate the usage of the "log reducer"
-   functionality:
-   a. Filter out the debug layer/level matched logs when control methods
-      are being evaluated:
-      # cd /sys/module/acpi/parameters
-      # echo "0xXXXXXXXX" > trace_debug_layer
-      # echo "0xYYYYYYYY" > trace_debug_level
-      # echo "enable" > trace_state
-   b. Filter out the debug layer/level matched logs when the specified
-      control method is being evaluated:
-      # cd /sys/module/acpi/parameters
-      # echo "0xXXXXXXXX" > trace_debug_layer
-      # echo "0xYYYYYYYY" > trace_debug_level
-      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
-      # echo "method" > /sys/module/acpi/parameters/trace_state
-   c. Filter out the debug layer/level matched logs when the specified
-      control method is being evaluated for the first time:
-      # cd /sys/module/acpi/parameters
-      # echo "0xXXXXXXXX" > trace_debug_layer
-      # echo "0xYYYYYYYY" > trace_debug_level
-      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
-      # echo "method-once" > /sys/module/acpi/parameters/trace_state
-   Where:
-      0xXXXXXXXX/0xYYYYYYYY: Refer to Documentation/acpi/debug.txt for
-			     possible debug layer/level masking values.
-      \PPPP.AAAA.TTTT.HHHH: Full path of a control method that can be found
-			    in the ACPI namespace. It needn't be an entry
-			    of a control method evaluation.
-
-   B. AML tracer
-
-   There are special log entries added by the method tracing facility at
-   the "trace points" the AML interpreter starts/stops to execute a control
-   method, or an AML opcode. Note that the format of the log entries are
-   subject to change:
-     [    0.186427]   exdebug-0398 ex_trace_point        : Method Begin [0xf58394d8:\_SB.PCI0.LPCB.ECOK] execution.
-     [    0.186630]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905c88:If] execution.
-     [    0.186820]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905cc0:LEqual] execution.
-     [    0.187010]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905a20:-NamePath-] execution.
-     [    0.187214]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905a20:-NamePath-] execution.
-     [    0.187407]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905f60:One] execution.
-     [    0.187594]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905f60:One] execution.
-     [    0.187789]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905cc0:LEqual] execution.
-     [    0.187980]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905cc0:Return] execution.
-     [    0.188146]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905f60:One] execution.
-     [    0.188334]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905f60:One] execution.
-     [    0.188524]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905cc0:Return] execution.
-     [    0.188712]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905c88:If] execution.
-     [    0.188903]   exdebug-0398 ex_trace_point        : Method End [0xf58394d8:\_SB.PCI0.LPCB.ECOK] execution.
-
-   Developers can utilize these special log entries to track the AML
-   interpretion, thus can aid issue debugging and performance tuning. Note
-   that, as the "AML tracer" logs are implemented via ACPI_DEBUG_PRINT()
-   macro, CONFIG_ACPI_DEBUG is also required to be enabled for enabling
-   "AML tracer" logs.
-
-   The following command examples illustrate the usage of the "AML tracer"
-   functionality:
-   a. Filter out the method start/stop "AML tracer" logs when control
-      methods are being evaluated:
-      # cd /sys/module/acpi/parameters
-      # echo "0x80" > trace_debug_layer
-      # echo "0x10" > trace_debug_level
-      # echo "enable" > trace_state
-   b. Filter out the method start/stop "AML tracer" when the specified
-      control method is being evaluated:
-      # cd /sys/module/acpi/parameters
-      # echo "0x80" > trace_debug_layer
-      # echo "0x10" > trace_debug_level
-      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
-      # echo "method" > trace_state
-   c. Filter out the method start/stop "AML tracer" logs when the specified
-      control method is being evaluated for the first time:
-      # cd /sys/module/acpi/parameters
-      # echo "0x80" > trace_debug_layer
-      # echo "0x10" > trace_debug_level
-      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
-      # echo "method-once" > trace_state
-   d. Filter out the method/opcode start/stop "AML tracer" when the
-      specified control method is being evaluated:
-      # cd /sys/module/acpi/parameters
-      # echo "0x80" > trace_debug_layer
-      # echo "0x10" > trace_debug_level
-      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
-      # echo "opcode" > trace_state
-   e. Filter out the method/opcode start/stop "AML tracer" when the
-      specified control method is being evaluated for the first time:
-      # cd /sys/module/acpi/parameters
-      # echo "0x80" > trace_debug_layer
-      # echo "0x10" > trace_debug_level
-      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
-      # echo "opcode-opcode" > trace_state
-
-  Note that all above method tracing facility related module parameters can
-  be used as the boot parameters, for example:
-      acpi.trace_debug_layer=0x80 acpi.trace_debug_level=0x10 \
-      acpi.trace_method_name=\_SB.LID0._LID acpi.trace_state=opcode-once
-
-2. Interface descriptions:
-
-   All method tracing functions can be configured via ACPI module
-   parameters that are accessible at /sys/module/acpi/parameters/:
-
-   trace_method_name
-	The full path of the AML method that the user wants to trace.
-	Note that the full path shouldn't contain the trailing "_"s in its
-	name segments but may contain "\" to form an absolute path.
-
-   trace_debug_layer
-	The temporary debug_layer used when the tracing feature is enabled.
-	Using ACPI_EXECUTER (0x80) by default, which is the debug_layer
-	used to match all "AML tracer" logs.
-
-   trace_debug_level
-	The temporary debug_level used when the tracing feature is enabled.
-	Using ACPI_LV_TRACE_POINT (0x10) by default, which is the
-	debug_level used to match all "AML tracer" logs.
-
-   trace_state
-	The status of the tracing feature.
-	Users can enable/disable this debug tracing feature by executing
-	the following command:
-	    # echo string > /sys/module/acpi/parameters/trace_state
-	Where "string" should be one of the following:
-	"disable"
-	    Disable the method tracing feature.
-	"enable"
-	    Enable the method tracing feature.
-	    ACPICA debugging messages matching
-	    "trace_debug_layer/trace_debug_level" during any method
-	    execution will be logged.
-	"method"
-	    Enable the method tracing feature.
-	    ACPICA debugging messages matching
-	    "trace_debug_layer/trace_debug_level" during method execution
-	    of "trace_method_name" will be logged.
-	"method-once"
-	    Enable the method tracing feature.
-	    ACPICA debugging messages matching
-	    "trace_debug_layer/trace_debug_level" during method execution
-	    of "trace_method_name" will be logged only once.
-	"opcode"
-	    Enable the method tracing feature.
-	    ACPICA debugging messages matching
-	    "trace_debug_layer/trace_debug_level" during method/opcode
-	    execution of "trace_method_name" will be logged.
-	"opcode-once"
-	    Enable the method tracing feature.
-	    ACPICA debugging messages matching
-	    "trace_debug_layer/trace_debug_level" during method/opcode
-	    execution of "trace_method_name" will be logged only once.
-	Note that, the difference between the "enable" and other feature
-        enabling options are:
-	1. When "enable" is specified, since
-	   "trace_debug_layer/trace_debug_level" shall apply to all control
-	   method evaluations, after configuring "trace_state" to "enable",
-	   "trace_method_name" will be reset to NULL.
-	2. When "method/opcode" is specified, if
-	   "trace_method_name" is NULL when "trace_state" is configured to
-	   these options, the "trace_debug_layer/trace_debug_level" will
-	   apply to all control method evaluations.

-Abstract:
-
-The Linux ACPI subsystem converts ACPI namespace objects into a Linux
-device tree under the /sys/devices/LNXSYSTEM:00 and updates it upon

-1. ACPI Definition Blocks
-
-   The ACPI firmware sets up RSDP (Root System Description Pointer) in the
-   system memory address space pointing to the XSDT (Extended System
-   Description Table).  The XSDT always points to the FADT (Fixed ACPI
-   Description Table) using its first entry, the data within the FADT
-   includes various fixed-length entries that describe fixed ACPI features
-   of the hardware.  The FADT contains a pointer to the DSDT
-   (Differentiated System Descripition Table).  The XSDT also contains
-   entries pointing to possibly multiple SSDTs (Secondary System
-   Description Table).
-
-   The DSDT and SSDT data is organized in data structures called definition
-   blocks that contain definitions of various objects, including ACPI
-   control methods, encoded in AML (ACPI Machine Language).  The data block
-   of the DSDT along with the contents of SSDTs represents a hierarchical
-   data structure called the ACPI namespace whose topology reflects the
-   structure of the underlying hardware platform.
-
-   The relationships between ACPI System Definition Tables described above
-   are illustrated in the following diagram.
-

-
-   NOTE: RSDP can also contain a pointer to the RSDT (Root System
-         Description Table).  Platforms provide RSDT to enable
-         compatibility with ACPI 1.0 operating systems.  The OS is expected
-         to use XSDT, if present.
-
-
-2. Example ACPI Namespace
-
-   All definition blocks are loaded into a single namespace.  The namespace
-   is a hierarchy of objects identified by names and paths.
-   The following naming conventions apply to object names in the ACPI
-   namespace:
-   1. All names are 32 bits long.
-   2. The first byte of a name must be one of 'A' - 'Z', '_'.
-   3. Each of the remaining bytes of a name must be one of 'A' - 'Z', '0'
-      - '9', '_'.
-   4. Names starting with '_' are reserved by the ACPI specification.
-   5. The '\' symbol represents the root of the namespace (i.e. names
-      prepended with '\' are relative to the namespace root).
-   6. The '^' symbol represents the parent of the current namespace node
-      (i.e. names prepended with '^' are relative to the parent of the
-      current namespace node).
-
-   The figure below shows an example ACPI namespace.

-3. Linux ACPI Device Objects
-
-   The Linux kernel's core ACPI subsystem creates struct acpi_device
-   objects for ACPI namespace objects representing devices, power resources
-   processors, thermal zones.  Those objects are exported to user space via
-   sysfs as directories in the subtree under /sys/devices/LNXSYSTM:00.  The
-   format of their names is <bus_id:instance>, where 'bus_id' refers to the
-   ACPI namespace representation of the given object and 'instance' is used
-   for distinguishing different object of the same 'bus_id' (it is
-   two-digit decimal representation of an unsigned integer).
-
-   The value of 'bus_id' depends on the type of the object whose name it is
-   part of as listed in the table below.
-
-                +---+-----------------+-------+----------+
-                |   | Object/Feature  | Table | bus_id   |

-
-                 Table 1. ACPI Namespace Objects Mapping
-
-   The following rules apply when creating struct acpi_device objects on
-   the basis of the contents of ACPI System Description Tables (as
-   indicated by the letter in the first column and the notation in the
-   second column of the table above):
-   N:
-      The object's source is an ACPI namespace node (as indicated by the
-      named object's type in the second column).  In that case the object's
-      directory in sysfs will contain the 'path' attribute whose value is
-      the full path to the node from the namespace root.
-   F:
-      The struct acpi_device object is created for a fixed hardware
-      feature (as indicated by the fixed feature flag's name in the second
-      column), so its sysfs directory will not contain the 'path'
-      attribute.
-   M:
-      The struct acpi_device object is created for an ACPI namespace node
-      with specific control methods (as indicated by the ACPI defined
-      device's type in the second column).  The 'path' attribute containing
-      its namespace path will be present in its sysfs directory.  For
-      example, if the _BCL method is present for an ACPI namespace node, a
-      struct acpi_device object with LNXVIDEO 'bus_id' will be created for
-      it.
-
-   The third column of the above table indicates which ACPI System
-   Description Tables contain information used for the creation of the
-   struct acpi_device objects represented by the given row (xSDT means DSDT
-   or SSDT).
-
-   The forth column of the above table indicates the 'bus_id' generation
-   rule of the struct acpi_device object:
-   _HID:
-      _HID in the last column of the table means that the object's bus_id
-      is derived from the _HID/_CID identification objects present under
-      the corresponding ACPI namespace node. The object's sysfs directory
-      will then contain the 'hid' and 'modalias' attributes that can be
-      used to retrieve the _HID and _CIDs of that object.
-   LNXxxxxx:
-      The 'modalias' attribute is also present for struct acpi_device
-      objects having bus_id of the "LNXxxxxx" form (pseudo devices), in
-      which cases it contains the bus_id string itself.
-   device:
-      'device' in the last column of the table indicates that the object's
-      bus_id cannot be determined from _HID/_CID of the corresponding
-      ACPI namespace node, although that object represents a device (for
-      example, it may be a PCI device with _ADR defined and without _HID
-      or _CID).  In that case the string 'device' will be used as the
-      object's bus_id.
-
-
-4. Linux ACPI Physical Device Glue
-
-   ACPI device (i.e. struct acpi_device) objects may be linked to other
-   objects in the Linux' device hierarchy that represent "physical" devices
-   (for example, devices on the PCI bus).  If that happens, it means that
-   the ACPI device object is a "companion" of a device otherwise
-   represented in a different way and is used (1) to provide configuration
-   information on that device which cannot be obtained by other means and
-   (2) to do specific things to the device with the help of its ACPI
-   control methods.  One ACPI device object may be linked this way to
-   multiple "physical" devices.
-
-   If an ACPI device object is linked to a "physical" device, its sysfs
-   directory contains the "physical_node" symbolic link to the sysfs
-   directory of the target device object.  In turn, the target device's
-   sysfs directory will then contain the "firmware_node" symbolic link to
-   the sysfs directory of the companion ACPI device object.
-   The linking mechanism relies on device identification provided by the
-   ACPI namespace.  For example, if there's an ACPI namespace object
-   representing a PCI device (i.e. a device object under an ACPI namespace
-   object representing a PCI bridge) whose _ADR returns 0x00020000 and the
-   bus number of the parent PCI bridge is 0, the sysfs directory
-   representing the struct acpi_device object created for that ACPI
-   namespace object will contain the 'physical_node' symbolic link to the
-   /sys/devices/pci0000:00/0000:00:02:0/ sysfs directory of the
-   corresponding PCI device.
-
-   The linking mechanism is generally bus-specific.  The core of its
-   implementation is located in the drivers/acpi/glue.c file, but there are
-   complementary parts depending on the bus types in question located
-   elsewhere.  For example, the PCI-specific part of it is located in
-   drivers/pci/pci-acpi.c.
-
-
-5. Example Linux ACPI Device Tree

-   The sysfs hierarchy of struct acpi_device objects corresponding to the
-   example ACPI namespace illustrated in Figure 2 with the addition of
-   fixed PWR_BUTTON/SLP_BUTTON devices is shown below.

-ACPI _OSI and _REV methods
---------------------------
-
-An ACPI BIOS can use the "Operating System Interfaces" method (_OSI)
-to find out what the operating system supports. Eg. If BIOS
-AML code includes _OSI("XYZ"), the kernel's AML interpreter
-can evaluate that method, look to see if it supports 'XYZ'
-and answer YES or NO to the BIOS.
-
-The ACPI _REV method returns the "Revision of the ACPI specification
-that OSPM supports"
-
-This document explains how and why the BIOS and Linux should use these methods.
-It also explains how and why they are widely misused.
-
-How to use _OSI
----------------
-
-Linux runs on two groups of machines -- those that are tested by the OEM
-to be compatible with Linux, and those that were never tested with Linux,
-but where Linux was installed to replace the original OS (Windows or OSX).
-
-The larger group is the systems tested to run only Windows.  Not only that,
-but many were tested to run with just one specific version of Windows.
-So even though the BIOS may use _OSI to query what version of Windows is running,
-only a single path through the BIOS has actually been tested.
-Experience shows that taking untested paths through the BIOS
-exposes Linux to an entire category of BIOS bugs.
-For this reason, Linux _OSI defaults must continue to claim compatibility
-with all versions of Windows.
-
-But Linux isn't actually compatible with Windows, and the Linux community
-has also been hurt with regressions when Linux adds the latest version of
-Windows to its list of _OSI strings.  So it is possible that additional strings
-will be more thoroughly vetted before shipping upstream in the future.
-But it is likely that they will all eventually be added.
-
-What should an OEM do if they want to support Linux and Windows
-using the same BIOS image?  Often they need to do something different
-for Linux to deal with how Linux is different from Windows.
-Here the BIOS should ask exactly what it wants to know:
-
-_OSI("Linux-OEM-my_interface_name")
-where 'OEM' is needed if this is an OEM-specific hook,
-and 'my_interface_name' describes the hook, which could be a
-quirk, a bug, or a bug-fix.
-
-In addition, the OEM should send a patch to upstream Linux
-via the linux-acpi@vger.kernel.org mailing list.  When that patch
-is checked into Linux, the OS will answer "YES" when the BIOS
-on the OEM's system uses _OSI to ask if the interface is supported
-by the OS.  Linux distributors can back-port that patch for Linux
-pre-installs, and it will be included by all distributions that
-re-base to upstream.  If the distribution can not update the kernel binary,
-they can also add an acpi_osi=Linux-OEM-my_interface_name
-cmdline parameter to the boot loader, as needed.
-
-If the string refers to a feature where the upstream kernel
-eventually grows support, a patch should be sent to remove
-the string when that support is added to the kernel.
-
-That was easy.  Read on, to find out how to do it wrong.
-
-Before _OSI, there was _OS
---------------------------
-
-ACPI 1.0 specified "_OS" as an
-"object that evaluates to a string that identifies the operating system."
-
-The ACPI BIOS flow would include an evaluation of _OS, and the AML
-interpreter in the kernel would return to it a string identifying the OS:
-
-Windows 98, SE: "Microsoft Windows"
-Windows ME: "Microsoft WindowsME:Millenium Edition"
-Windows NT: "Microsoft Windows NT"
-
-The idea was on a platform tasked with running multiple OS's,
-the BIOS could use _OS to enable devices that an OS
-might support, or enable quirks or bug workarounds
-necessary to make the platform compatible with that pre-existing OS.
-
-But _OS had fundamental problems.  First, the BIOS needed to know the name
-of every possible version of the OS that would run on it, and needed to know
-all the quirks of those OS's.  Certainly it would make more sense
-for the BIOS to ask *specific* things of the OS, such
-"do you support a specific interface", and thus in ACPI 3.0,
-_OSI was born to replace _OS.
-
-_OS was abandoned, though even today, many BIOS look for
-_OS "Microsoft Windows NT", though it seems somewhat far-fetched
-that anybody would install those old operating systems
-over what came with the machine.
-
-Linux answers "Microsoft Windows NT" to please that BIOS idiom.
-That is the *only* viable strategy, as that is what modern Windows does,
-and so doing otherwise could steer the BIOS down an untested path.
-
-_OSI is born, and immediately misused
---------------------------------------
-
-With _OSI, the *BIOS* provides the string describing an interface,
-and asks the OS: "YES/NO, are you compatible with this interface?"
-
-eg. _OSI("3.0 Thermal Model") would return TRUE if the OS knows how
-to deal with the thermal extensions made to the ACPI 3.0 specification.
-An old OS that doesn't know about those extensions would answer FALSE,
-and a new OS may be able to return TRUE.
-
-For an OS-specific interface, the ACPI spec said that the BIOS and the OS
-were to agree on a string of the form such as "Windows-interface_name".
-
-But two bad things happened.  First, the Windows ecosystem used _OSI
-not as designed, but as a direct replacement for _OS -- identifying
-the OS version, rather than an OS supported interface.  Indeed, right
-from the start, the ACPI 3.0 spec itself codified this misuse
-in example code using _OSI("Windows 2001").
-
-This misuse was adopted and continues today.
-
-Linux had no choice but to also return TRUE to _OSI("Windows 2001")
-and its successors.  To do otherwise would virtually guarantee breaking
-a BIOS that has been tested only with that _OSI returning TRUE.
-
-This strategy is problematic, as Linux is never completely compatible with
-the latest version of Windows, and sometimes it takes more than a year
-to iron out incompatibilities.
-
-Not to be out-done, the Linux community made things worse by returning TRUE
-to _OSI("Linux").  Doing so is even worse than the Windows misuse
-of _OSI, as "Linux" does not even contain any version information.
-_OSI("Linux") led to some BIOS' malfunctioning due to BIOS writer's
-using it in untested BIOS flows.  But some OEM's used _OSI("Linux")
-in tested flows to support real Linux features.  In 2009, Linux
-removed _OSI("Linux"), and added a cmdline parameter to restore it
-for legacy systems still needed it.  Further a BIOS_BUG warning prints
-for all BIOS's that invoke it.
-
-No BIOS should use _OSI("Linux").
-
-The result is a strategy for Linux to maximize compatibility with
-ACPI BIOS that are tested on Windows machines.  There is a real risk
-of over-stating that compatibility; but the alternative has often been
-catastrophic failure resulting from the BIOS taking paths that
-were never validated under *any* OS.
-
-Do not use _REV
----------------
-
-Since _OSI("Linux") went away, some BIOS writers used _REV
-to support Linux and Windows differences in the same BIOS.
-
-_REV was defined in ACPI 1.0 to return the version of ACPI
-supported by the OS and the OS AML interpreter.
-
-Modern Windows returns _REV = 2.  Linux used ACPI_CA_SUPPORT_LEVEL,
-which would increment, based on the version of the spec supported.
-
-Unfortunately, _REV was also misused.  eg. some BIOS would check
-for _REV = 3, and do something for Linux, but when Linux returned
-_REV = 4, that support broke.
-
-In response to this problem, Linux returns _REV = 2 always,
-from mid-2015 onward.  The ACPI specification will also be updated
-to reflect that _REV is deprecated, and always returns 2.
-
-Apple Mac and _OSI("Darwin")
-----------------------------
-
-On Apple's Mac platforms, the ACPI BIOS invokes _OSI("Darwin")
-to determine if the machine is running Apple OSX.
-
-Like Linux's _OSI("*Windows*") strategy, Linux defaults to
-answering YES to _OSI("Darwin") to enable full access
-to the hardware and validated BIOS paths seen by OSX.
-Just like on Windows-tested platforms, this strategy has risks.
-
-Starting in Linux-3.18, the kernel answered YES to _OSI("Darwin")
-for the purpose of enabling Mac Thunderbolt support.  Further,
-if the kernel noticed _OSI("Darwin") being invoked, it additionally
-disabled all _OSI("*Windows*") to keep poorly written Mac BIOS
-from going down untested combinations of paths.
-
-The Linux-3.18 change in default caused power regressions on Mac
-laptops, and the 3.18 implementation did not allow changing
-the default via cmdline "acpi_osi=!Darwin".  Linux-4.7 fixed
-the ability to use acpi_osi=!Darwin as a workaround, and
-we hope to see Mac Thunderbolt power management support in Linux-4.11.

-ACPI Scan Handlers
-
-Copyright (C) 2012, Intel Corporation
-Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
-
-During system initialization and ACPI-based device hot-add, the ACPI namespace
-is scanned in search of device objects that generally represent various pieces
-of hardware.  This causes a struct acpi_device object to be created and
-registered with the driver core for every device object in the ACPI namespace
-and the hierarchy of those struct acpi_device objects reflects the namespace
-layout (i.e. parent device objects in the namespace are represented by parent
-struct acpi_device objects and analogously for their children).  Those struct
-acpi_device objects are referred to as "device nodes" in what follows, but they
-should not be confused with struct device_node objects used by the Device Trees
-parsing code (although their role is analogous to the role of those objects).
-
-During ACPI-based device hot-remove device nodes representing pieces of hardware
-being removed are unregistered and deleted.
-
-The core ACPI namespace scanning code in drivers/acpi/scan.c carries out basic
-initialization of device nodes, such as retrieving common configuration
-information from the device objects represented by them and populating them with
-appropriate data, but some of them require additional handling after they have
-been registered.  For example, if the given device node represents a PCI host
-bridge, its registration should cause the PCI bus under that bridge to be
-enumerated and PCI devices on that bus to be registered with the driver core.
-Similarly, if the device node represents a PCI interrupt link, it is necessary
-to configure that link so that the kernel can use it.
-
-Those additional configuration tasks usually depend on the type of the hardware
-component represented by the given device node which can be determined on the
-basis of the device node's hardware ID (HID).  They are performed by objects
-called ACPI scan handlers represented by the following structure:
-
-struct acpi_scan_handler {
-	const struct acpi_device_id *ids;
-	struct list_head list_node;
-	int (*attach)(struct acpi_device *dev, const struct acpi_device_id *id);
-	void (*detach)(struct acpi_device *dev);
-};
-
-where ids is the list of IDs of device nodes the given handler is supposed to
-take care of, list_node is the hook to the global list of ACPI scan handlers
-maintained by the ACPI core and the .attach() and .detach() callbacks are
-executed, respectively, after registration of new device nodes and before
-unregistration of device nodes the handler attached to previously.
-
-The namespace scanning function, acpi_bus_scan(), first registers all of the
-device nodes in the given namespace scope with the driver core.  Then, it tries
-to match a scan handler against each of them using the ids arrays of the
-available scan handlers.  If a matching scan handler is found, its .attach()
-callback is executed for the given device node.  If that callback returns 1,
-that means that the handler has claimed the device node and is now responsible
-for carrying out any additional configuration tasks related to it.  It also will
-be responsible for preparing the device node for unregistration in that case.
-The device node's handler field is then populated with the address of the scan
-handler that has claimed it.
-
-If the .attach() callback returns 0, it means that the device node is not
-interesting to the given scan handler and may be matched against the next scan
-handler in the list.  If it returns a (negative) error code, that means that
-the namespace scan should be terminated due to a serious error.  The error code
-returned should then reflect the type of the error.
-
-The namespace trimming function, acpi_bus_trim(), first executes .detach()
-callbacks from the scan handlers of all device nodes in the given namespace
-scope (if they have scan handlers).  Next, it unregisters all of the device
-nodes in that scope.
-
-ACPI scan handlers can be added to the list maintained by the ACPI core with the
-help of the acpi_scan_add_handler() function taking a pointer to the new scan
-handler as an argument.  The order in which scan handlers are added to the list
-is the order in which they are matched against device nodes during namespace
-scans.
-
-All scan handles must be added to the list before acpi_bus_scan() is run for the
-first time and they cannot be removed from it.

-In order to support ACPI open-ended hardware configurations (e.g. development
-boards) we need a way to augment the ACPI configuration provided by the firmware
-image. A common example is connecting sensors on I2C / SPI buses on development
-boards.
-
-Although this can be accomplished by creating a kernel platform driver or
-recompiling the firmware image with updated ACPI tables, neither is practical:
-the former proliferates board specific kernel code while the latter requires
-access to firmware tools which are often not publicly available.
-
-Because ACPI supports external references in AML code a more practical
-way to augment firmware ACPI configuration is by dynamically loading
-user defined SSDT tables that contain the board specific information.
-
-For example, to enumerate a Bosch BMA222E accelerometer on the I2C bus of the
-Minnowboard MAX development board exposed via the LSE connector [1], the
-following ASL code can be used:
-
-DefinitionBlock ("minnowmax.aml", "SSDT", 1, "Vendor", "Accel", 0x00000003)
-{
-    External (\_SB.I2C6, DeviceObj)

-    Scope (\_SB.I2C6)

-                    I2cSerialBus (0x0018, ControllerInitiated, 0x00061A80,

-
-[1] http://wiki.minnowboard.org/MinnowBoard_MAX#Low_Speed_Expansion_Connector_.28Top.29
-
-The resulting AML code can then be loaded by the kernel using one of the methods
-below.
-
-== Loading ACPI SSDTs from initrd ==
-
-This option allows loading of user defined SSDTs from initrd and it is useful
-when the system does not support EFI or when there is not enough EFI storage.
-
-It works in a similar way with initrd based ACPI tables override/upgrade: SSDT
-aml code must be placed in the first, uncompressed, initrd under the
-"kernel/firmware/acpi" path. Multiple files can be used and this will translate
-in loading multiple tables. Only SSDT and OEM tables are allowed. See
-initrd_table_override.txt for more details.
-
-Here is an example:
-
-# Add the raw ACPI tables to an uncompressed cpio archive.
-# They must be put into a /kernel/firmware/acpi directory inside the
-# cpio archive.
-# The uncompressed cpio archive must be the first.
-# Other, typically compressed cpio archives, must be
-# concatenated on top of the uncompressed one.
-mkdir -p kernel/firmware/acpi
-cp ssdt.aml kernel/firmware/acpi
-
-# Create the uncompressed cpio archive and concatenate the original initrd
-# on top:
-find kernel | cpio -H newc --create > /boot/instrumented_initrd
-cat /boot/initrd >>/boot/instrumented_initrd
-
-== Loading ACPI SSDTs from EFI variables ==
-
-This is the preferred method, when EFI is supported on the platform, because it
-allows a persistent, OS independent way of storing the user defined SSDTs. There
-is also work underway to implement EFI support for loading user defined SSDTs
-and using this method will make it easier to convert to the EFI loading
-mechanism when that will arrive.
-
-In order to load SSDTs from an EFI variable the efivar_ssdt kernel command line
-parameter can be used. The argument for the option is the variable name to
-use. If there are multiple variables with the same name but with different
-vendor GUIDs, all of them will be loaded.
-
-In order to store the AML code in an EFI variable the efivarfs filesystem can be
-used. It is enabled and mounted by default in /sys/firmware/efi/efivars in all
-recent distribution.
-
-Creating a new file in /sys/firmware/efi/efivars will automatically create a new
-EFI variable. Updating a file in /sys/firmware/efi/efivars will update the EFI
-variable. Please note that the file name needs to be specially formatted as
-"Name-GUID" and that the first 4 bytes in the file (little-endian format)
-represent the attributes of the EFI variable (see EFI_VARIABLE_MASK in
-include/linux/efi.h). Writing to the file must also be done with one write
-operation.
-
-For example, you can use the following bash script to create/update an EFI
-variable with the content from a given file:
-
-#!/bin/sh -e
-
-while ! [ -z "$1" ]; do
-        case "$1" in
-        "-f") filename="$2"; shift;;
-        "-g") guid="$2"; shift;;
-        *) name="$1";;
-        esac
-        shift
-done
-
-usage()
-{
-        echo "Syntax: ${0##*/} -f filename [ -g guid ] name"
-        exit 1
-}
-
-[ -n "$name" -a -f "$filename" ] || usage
-
-EFIVARFS="/sys/firmware/efi/efivars"
-
-[ -d "$EFIVARFS" ] || exit 2
-
-if stat -tf $EFIVARFS | grep -q -v de5e81e4; then
-        mount -t efivarfs none $EFIVARFS
-fi
-
-# try to pick up an existing GUID
-[ -n "$guid" ] || guid=$(find "$EFIVARFS" -name "$name-*" | head -n1 | cut -f2- -d-)
-
-# use a randomly generated GUID
-[ -n "$guid" ] || guid="$(cat /proc/sys/kernel/random/uuid)"
-
-# efivarfs expects all of the data in one write
-tmp=$(mktemp)
-/bin/echo -ne "\007\000\000\000" | cat - $filename > $tmp
-dd if=$tmp of="$EFIVARFS/$name-$guid" bs=$(stat -c %s $tmp)
-rm $tmp
-
-== Loading ACPI SSDTs from configfs ==
-
-This option allows loading of user defined SSDTs from userspace via the configfs
-interface. The CONFIG_ACPI_CONFIGFS option must be select and configfs must be
-mounted. In the following examples, we assume that configfs has been mounted in
-/config.
-
-New tables can be loading by creating new directories in /config/acpi/table/ and
-writing the SSDT aml code in the aml attribute:
-
-cd /config/acpi/table
-mkdir my_ssdt
-cat ~/ssdt.aml > my_ssdt/aml

-ACPI video extensions
-~~~~~~~~~~~~~~~~~~~~~
-
-This driver implement the ACPI Extensions For Display Adapters for
-integrated graphics devices on motherboard, as specified in ACPI 2.0
-Specification, Appendix B, allowing to perform some basic control like
-defining the video POST device, retrieving EDID information or to
-setup a video output, etc.  Note that this is an ref. implementation
-only.  It may or may not work for your integrated video device.
-
-The ACPI video driver does 3 things regarding backlight control:
-
-1 Export a sysfs interface for user space to control backlight level
-
-If the ACPI table has a video device, and acpi_backlight=vendor kernel
-command line is not present, the driver will register a backlight device
-and set the required backlight operation structure for it for the sysfs
-interface control. For every registered class device, there will be a
-directory named acpi_videoX under /sys/class/backlight.
-
-The backlight sysfs interface has a standard definition here:
-Documentation/ABI/stable/sysfs-class-backlight.
-
-And what ACPI video driver does is:
-actual_brightness: on read, control method _BQC will be evaluated to
-get the brightness level the firmware thinks it is at;
-bl_power: not implemented, will set the current brightness instead;
-brightness: on write, control method _BCM will run to set the requested
-brightness level;
-max_brightness: Derived from the _BCL package(see below);
-type: firmware
-
-Note that ACPI video backlight driver will always use index for
-brightness, actual_brightness and max_brightness. So if we have
-the following _BCL package:
-
-Method (_BCL, 0, NotSerialized)
-{
-	Return (Package (0x0C)
-	{
-		0x64,
-		0x32,
-		0x0A,
-		0x14,
-		0x1E,
-		0x28,
-		0x32,
-		0x3C,
-		0x46,
-		0x50,
-		0x5A,
-		0x64
-	})
-}
-
-The first two levels are for when laptop are on AC or on battery and are
-not used by Linux currently. The remaining 10 levels are supported levels
-that we can choose from. The applicable index values are from 0 (that
-corresponds to the 0x0A brightness value) to 9 (that corresponds to the
-0x64 brightness value) inclusive. Each of those index values is regarded
-as a "brightness level" indicator. Thus from the user space perspective
-the range of available brightness levels is from 0 to 9 (max_brightness)
-inclusive.
-
-2 Notify user space about hotkey event
-
-There are generally two cases for hotkey event reporting:
-i) For some laptops, when user presses the hotkey, a scancode will be
-   generated and sent to user space through the input device created by
-   the keyboard driver as a key type input event, with proper remap, the
-   following key code will appear to user space:
-
-	EV_KEY, KEY_BRIGHTNESSUP
-	EV_KEY, KEY_BRIGHTNESSDOWN
-	etc.
-
-For this case, ACPI video driver does not need to do anything(actually,
-it doesn't even know this happened).
-
-ii) For some laptops, the press of the hotkey will not generate the
-    scancode, instead, firmware will notify the video device ACPI node
-    about the event. The event value is defined in the ACPI spec. ACPI
-    video driver will generate an key type input event according to the
-    notify value it received and send the event to user space through the
-    input device it created:
-
-	event		keycode
-	0x86		KEY_BRIGHTNESSUP
-	0x87		KEY_BRIGHTNESSDOWN
-	etc.
-
-so this would lead to the same effect as case i) now.
-
-Once user space tool receives this event, it can modify the backlight
-level through the sysfs interface.
-
-3 Change backlight level in the kernel
-
-This works for machines covered by case ii) in Section 2. Once the driver
-received a notification, it will set the backlight level accordingly. This does
-not affect the sending of event to user space, they are always sent to user
-space regardless of whether or not the video module controls the backlight level
-directly. This behaviour can be controlled through the brightness_switch_enabled
-module parameter as documented in admin-guide/kernel-parameters.rst. It is recommended to
-disable this behaviour once a GUI environment starts up and wants to have full
-control of the backlight level.

+================================
+Upgrading ACPI tables via initrd
+================================
+
+What is this about
+==================
+
+If the ACPI_TABLE_UPGRADE compile option is true, it is possible to
+upgrade the ACPI execution environment that is defined by the ACPI tables
+via upgrading the ACPI tables provided by the BIOS with an instrumented,
+modified, more recent version one, or installing brand new ACPI tables.
+
+When building initrd with kernel in a single image, option
+ACPI_TABLE_OVERRIDE_VIA_BUILTIN_INITRD should also be true for this
+feature to work.
+
+For a full list of ACPI tables that can be upgraded/installed, take a look
+at the char `*table_sigs[MAX_ACPI_SIGNATURE];` definition in
+drivers/acpi/tables.c.
+
+All ACPI tables iasl (Intel's ACPI compiler and disassembler) knows should
+be overridable, except:
+
+  - ACPI_SIG_RSDP (has a signature of 6 bytes)
+  - ACPI_SIG_FACS (does not have an ordinary ACPI table header)
+
+Both could get implemented as well.
+
+
+What is this for
+================
+
+Complain to your platform/BIOS vendor if you find a bug which is so severe
+that a workaround is not accepted in the Linux kernel. And this facility
+allows you to upgrade the buggy tables before your platform/BIOS vendor
+releases an upgraded BIOS binary.
+
+This facility can be used by platform/BIOS vendors to provide a Linux
+compatible environment without modifying the underlying platform firmware.
+
+This facility also provides a powerful feature to easily debug and test
+ACPI BIOS table compatibility with the Linux kernel by modifying old
+platform provided ACPI tables or inserting new ACPI tables.
+
+It can and should be enabled in any kernel because there is no functional
+change with not instrumented initrds.
+
+
+How does it work
+================
+::
+
+  # Extract the machine's ACPI tables:
+  cd /tmp
+  acpidump >acpidump
+  acpixtract -a acpidump
+  # Disassemble, modify and recompile them:
+  iasl -d *.dat
+  # For example add this statement into a _PRT (PCI Routing Table) function
+  # of the DSDT:
+  Store("HELLO WORLD", debug)
+  # And increase the OEM Revision. For example, before modification:
+  DefinitionBlock ("DSDT.aml", "DSDT", 2, "INTEL ", "TEMPLATE", 0x00000000)
+  # After modification:
+  DefinitionBlock ("DSDT.aml", "DSDT", 2, "INTEL ", "TEMPLATE", 0x00000001)
+  iasl -sa dsdt.dsl
+  # Add the raw ACPI tables to an uncompressed cpio archive.
+  # They must be put into a /kernel/firmware/acpi directory inside the cpio
+  # archive. Note that if the table put here matches a platform table
+  # (similar Table Signature, and similar OEMID, and similar OEM Table ID)
+  # with a more recent OEM Revision, the platform table will be upgraded by
+  # this table. If the table put here doesn't match a platform table
+  # (dissimilar Table Signature, or dissimilar OEMID, or dissimilar OEM Table
+  # ID), this table will be appended.
+  mkdir -p kernel/firmware/acpi
+  cp dsdt.aml kernel/firmware/acpi
+  # A maximum of "NR_ACPI_INITRD_TABLES (64)" tables are currently allowed
+  # (see osl.c):
+  iasl -sa facp.dsl
+  iasl -sa ssdt1.dsl
+  cp facp.aml kernel/firmware/acpi
+  cp ssdt1.aml kernel/firmware/acpi
+  # The uncompressed cpio archive must be the first. Other, typically
+  # compressed cpio archives, must be concatenated on top of the uncompressed
+  # one. Following command creates the uncompressed cpio archive and
+  # concatenates the original initrd on top:
+  find kernel | cpio -H newc --create > /boot/instrumented_initrd
+  cat /boot/initrd >>/boot/instrumented_initrd
+  # reboot with increased acpi debug level, e.g. boot params:
+  acpi.debug_level=0x2 acpi.debug_layer=0xFFFFFFFF
+  # and check your syslog:
+  [    1.268089] ACPI: PCI Interrupt Routing Table [\_SB_.PCI0._PRT]
+  [    1.272091] [ACPI Debug]  String [0x0B] "HELLO WORLD"
+
+iasl is able to disassemble and recompile quite a lot different,
+also static ACPI tables.
+
+
+Where to retrieve userspace tools
+=================================
+
+iasl and acpixtract are part of Intel's ACPICA project:
+http://acpica.org/
+
+and should be packaged by distributions (for example in the acpica package
+on SUSE).
+
+acpidump can be found in Len Browns pmtools:
+ftp://kernel.org/pub/linux/kernel/people/lenb/acpi/utils/pmtools/acpidump
+
+This tool is also part of the acpica package on SUSE.
+Alternatively, used ACPI tables can be retrieved via sysfs in latest kernels:

+SSDT Overlays
+=============
+
+In order to support ACPI open-ended hardware configurations (e.g. development
+boards) we need a way to augment the ACPI configuration provided by the firmware
+image. A common example is connecting sensors on I2C / SPI buses on development
+boards.
+
+Although this can be accomplished by creating a kernel platform driver or
+recompiling the firmware image with updated ACPI tables, neither is practical:
+the former proliferates board specific kernel code while the latter requires
+access to firmware tools which are often not publicly available.
+
+Because ACPI supports external references in AML code a more practical
+way to augment firmware ACPI configuration is by dynamically loading
+user defined SSDT tables that contain the board specific information.
+
+For example, to enumerate a Bosch BMA222E accelerometer on the I2C bus of the
+Minnowboard MAX development board exposed via the LSE connector [1], the
+following ASL code can be used::
+
+    DefinitionBlock ("minnowmax.aml", "SSDT", 1, "Vendor", "Accel", 0x00000003)
+    {
+        External (\_SB.I2C6, DeviceObj)
+
+        Scope (\_SB.I2C6)
+        {
+            Device (STAC)
+            {
+                Name (_ADR, Zero)
+                Name (_HID, "BMA222E")
+
+                Method (_CRS, 0, Serialized)
+                {
+                    Name (RBUF, ResourceTemplate ()
+                    {
+                        I2cSerialBus (0x0018, ControllerInitiated, 0x00061A80,
+                                    AddressingMode7Bit, "\\_SB.I2C6", 0x00,
+                                    ResourceConsumer, ,)
+                        GpioInt (Edge, ActiveHigh, Exclusive, PullDown, 0x0000,
+                                "\\_SB.GPO2", 0x00, ResourceConsumer, , )
+                        { // Pin list
+                            0
+                        }
+                    })
+                    Return (RBUF)
+                }
+            }
+        }
+    }
+
+which can then be compiled to AML binary format::
+
+    $ iasl minnowmax.asl
+
+    Intel ACPI Component Architecture
+    ASL Optimizing Compiler version 20140214-64 [Mar 29 2014]

+

+
+[1] http://wiki.minnowboard.org/MinnowBoard_MAX#Low_Speed_Expansion_Connector_.28Top.29
+
+The resulting AML code can then be loaded by the kernel using one of the methods
+below.
+
+Loading ACPI SSDTs from initrd
+==============================
+
+This option allows loading of user defined SSDTs from initrd and it is useful
+when the system does not support EFI or when there is not enough EFI storage.
+
+It works in a similar way with initrd based ACPI tables override/upgrade: SSDT
+aml code must be placed in the first, uncompressed, initrd under the
+"kernel/firmware/acpi" path. Multiple files can be used and this will translate
+in loading multiple tables. Only SSDT and OEM tables are allowed. See
+initrd_table_override.txt for more details.
+
+Here is an example::
+
+    # Add the raw ACPI tables to an uncompressed cpio archive.
+    # They must be put into a /kernel/firmware/acpi directory inside the
+    # cpio archive.
+    # The uncompressed cpio archive must be the first.
+    # Other, typically compressed cpio archives, must be
+    # concatenated on top of the uncompressed one.
+    mkdir -p kernel/firmware/acpi
+    cp ssdt.aml kernel/firmware/acpi
+
+    # Create the uncompressed cpio archive and concatenate the original initrd
+    # on top:
+    find kernel | cpio -H newc --create > /boot/instrumented_initrd
+    cat /boot/initrd >>/boot/instrumented_initrd
+
+Loading ACPI SSDTs from EFI variables
+=====================================
+
+This is the preferred method, when EFI is supported on the platform, because it
+allows a persistent, OS independent way of storing the user defined SSDTs. There
+is also work underway to implement EFI support for loading user defined SSDTs
+and using this method will make it easier to convert to the EFI loading
+mechanism when that will arrive.
+
+In order to load SSDTs from an EFI variable the efivar_ssdt kernel command line
+parameter can be used. The argument for the option is the variable name to
+use. If there are multiple variables with the same name but with different
+vendor GUIDs, all of them will be loaded.
+
+In order to store the AML code in an EFI variable the efivarfs filesystem can be
+used. It is enabled and mounted by default in /sys/firmware/efi/efivars in all
+recent distribution.
+
+Creating a new file in /sys/firmware/efi/efivars will automatically create a new
+EFI variable. Updating a file in /sys/firmware/efi/efivars will update the EFI
+variable. Please note that the file name needs to be specially formatted as
+"Name-GUID" and that the first 4 bytes in the file (little-endian format)
+represent the attributes of the EFI variable (see EFI_VARIABLE_MASK in
+include/linux/efi.h). Writing to the file must also be done with one write
+operation.
+
+For example, you can use the following bash script to create/update an EFI
+variable with the content from a given file::
+
+    #!/bin/sh -e
+
+    while ! [ -z "$1" ]; do
+            case "$1" in
+            "-f") filename="$2"; shift;;
+            "-g") guid="$2"; shift;;
+            *) name="$1";;
+            esac
+            shift
+    done
+
+    usage()
+    {
+            echo "Syntax: ${0##*/} -f filename [ -g guid ] name"
+            exit 1
+    }
+
+    [ -n "$name" -a -f "$filename" ] || usage
+
+    EFIVARFS="/sys/firmware/efi/efivars"
+
+    [ -d "$EFIVARFS" ] || exit 2
+
+    if stat -tf $EFIVARFS | grep -q -v de5e81e4; then
+            mount -t efivarfs none $EFIVARFS
+    fi
+
+    # try to pick up an existing GUID
+    [ -n "$guid" ] || guid=$(find "$EFIVARFS" -name "$name-*" | head -n1 | cut -f2- -d-)
+
+    # use a randomly generated GUID
+    [ -n "$guid" ] || guid="$(cat /proc/sys/kernel/random/uuid)"
+
+    # efivarfs expects all of the data in one write
+    tmp=$(mktemp)
+    /bin/echo -ne "\007\000\000\000" | cat - $filename > $tmp
+    dd if=$tmp of="$EFIVARFS/$name-$guid" bs=$(stat -c %s $tmp)
+    rm $tmp
+
+Loading ACPI SSDTs from configfs
+================================
+
+This option allows loading of user defined SSDTs from userspace via the configfs
+interface. The CONFIG_ACPI_CONFIGFS option must be select and configfs must be
+mounted. In the following examples, we assume that configfs has been mounted in
+/config.
+
+New tables can be loading by creating new directories in /config/acpi/table/ and
+writing the SSDT aml code in the aml attribute::
+
+    cd /config/acpi/table
+    mkdir my_ssdt
+    cat ~/ssdt.aml > my_ssdt/aml

+case-insensitive file name lookups
+======================================================
+
+The case-insensitive file name lookup feature is supported on a
+per-directory basis, allowing the user to mix case-insensitive and
+case-sensitive directories in the same filesystem.  It is enabled by
+flipping the +F inode attribute of an empty directory.  The
+case-insensitive string match operation is only defined when we know how
+text in encoded in a byte sequence.  For that reason, in order to enable
+case-insensitive directories, the filesystem must have the
+casefold feature, which stores the filesystem-wide encoding
+model used.  By default, the charset adopted is the latest version of
+Unicode (12.1.0, by the time of this writing), encoded in the UTF-8
+form.  The comparison algorithm is implemented by normalizing the
+strings to the Canonical decomposition form, as defined by Unicode,
+followed by a byte per byte comparison.
+
+The case-awareness is name-preserving on the disk, meaning that the file
+name provided by userspace is a byte-per-byte match to what is actually
+written in the disk.  The Unicode normalization format used by the
+kernel is thus an internal representation, and not exposed to the
+userspace nor to the disk, with the important exception of disk hashes,
+used on large case-insensitive directories with DX feature.  On DX
+directories, the hash must be calculated using the casefolded version of
+the filename, meaning that the normalization format used actually has an
+impact on where the directory entry is stored.
+
+When we change from viewing filenames as opaque byte sequences to seeing
+them as encoded strings we need to address what happens when a program
+tries to create a file with an invalid name.  The Unicode subsystem
+within the kernel leaves the decision of what to do in this case to the
+filesystem, which select its preferred behavior by enabling/disabling
+the strict mode.  When Ext4 encounters one of those strings and the
+filesystem did not require strict mode, it falls back to considering the
+entire string as an opaque byte sequence, which still allows the user to
+operate on that file, but the case-insensitive lookups won't work.

+
+This vulnerability affects a wide range of Intel processors. The
+vulnerability is not present on:
+
+   - Processors from AMD, Centaur and other non Intel vendors
+
+   - Older processor models, where the CPU family is < 6
+
+   - A range of Intel ATOM processors (Cedarview, Cloverview, Lincroft,
+     Penwell, Pineview, Silvermont, Airmont, Merrifield)
+
+   - The Intel XEON PHI family
+
+   - Intel processors which have the ARCH_CAP_RDCL_NO bit set in the
+     IA32_ARCH_CAPABILITIES MSR. If the bit is set the CPU is not affected
+     by the Meltdown vulnerability either. These CPUs should become
+     available by end of 2018.
+
+Whether a processor is affected or not can be read out from the L1TF
+vulnerability file in sysfs. See :ref:`l1tf_sys_info`.

+
+Problem
+-------
+
+If an instruction accesses a virtual address for which the relevant page
+table entry (PTE) has the Present bit cleared or other reserved bits set,
+then speculative execution ignores the invalid PTE and loads the referenced
+data if it is present in the Level 1 Data Cache, as if the page referenced
+by the address bits in the PTE was still present and accessible.
+
+While this is a purely speculative mechanism and the instruction will raise
+a page fault when it is retired eventually, the pure act of loading the
+data and making it available to other speculative instructions opens up the
+opportunity for side channel attacks to unprivileged malicious code,
+similar to the Meltdown attack.
+
+While Meltdown breaks the user space to kernel space protection, L1TF
+allows to attack any physical memory address in the system and the attack
+works across all protection domains. It allows an attack of SGX and also
+works from inside virtual machines because the speculation bypasses the
+extended page table (EPT) protection mechanism.
+
+
+Attack scenarios
+----------------
+
+1. Malicious user space
+^^^^^^^^^^^^^^^^^^^^^^^
+
+   Operating Systems store arbitrary information in the address bits of a
+   PTE which is marked non present. This allows a malicious user space
+   application to attack the physical memory to which these PTEs resolve.
+   In some cases user-space can maliciously influence the information
+   encoded in the address bits of the PTE, thus making attacks more
+   deterministic and more practical.
+
+   The Linux kernel contains a mitigation for this attack vector, PTE
+   inversion, which is permanently enabled and has no performance
+   impact. The kernel ensures that the address bits of PTEs, which are not
+   marked present, never point to cacheable physical memory space.
+
+   A system with an up to date kernel is protected against attacks from
+   malicious user space applications.
+
+2. Malicious guest in a virtual machine
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+   The fact that L1TF breaks all domain protections allows malicious guest
+   OSes, which can control the PTEs directly, and malicious guest user
+   space applications, which run on an unprotected guest kernel lacking the
+   PTE inversion mitigation for L1TF, to attack physical host memory.
+
+   A special aspect of L1TF in the context of virtualization is symmetric
+   multi threading (SMT). The Intel implementation of SMT is called
+   HyperThreading. The fact that Hyperthreads on the affected processors
+   share the L1 Data Cache (L1D) is important for this. As the flaw allows
+   only to attack data which is present in L1D, a malicious guest running
+   on one Hyperthread can attack the data which is brought into the L1D by
+   the context which runs on the sibling Hyperthread of the same physical
+   core. This context can be host OS, host user space or a different guest.
+
+   If the processor does not support Extended Page Tables, the attack is
+   only possible, when the hypervisor does not sanitize the content of the
+   effective (shadow) page tables.
+
+   While solutions exist to mitigate these attack vectors fully, these
+   mitigations are not enabled by default in the Linux kernel because they
+   can affect performance significantly. The kernel provides several
+   mechanisms which can be utilized to address the problem depending on the
+   deployment scenario. The mitigations, their protection scope and impact
+   are described in the next sections.
+
+   The default mitigations and the rationale for choosing them are explained
+   at the end of this document. See :ref:`default_mitigations`.
+
+.. _l1tf_sys_info:
+
+L1TF system information
+-----------------------
+
+The Linux kernel provides a sysfs interface to enumerate the current L1TF
+status of the system: whether the system is vulnerable, and which
+mitigations are active. The relevant sysfs file is:
+
+/sys/devices/system/cpu/vulnerabilities/l1tf
+
+The possible values in this file are:
+
+  ===========================   ===============================
+  'Not affected'		The processor is not vulnerable
+  'Mitigation: PTE Inversion'	The host protection is active
+  ===========================   ===============================
+
+If KVM/VMX is enabled and the processor is vulnerable then the following
+information is appended to the 'Mitigation: PTE Inversion' part:
+
+  - SMT status:
+
+    =====================  ================
+    'VMX: SMT vulnerable'  SMT is enabled
+    'VMX: SMT disabled'    SMT is disabled
+    =====================  ================
+
+  - L1D Flush mode:
+
+    ================================  ====================================
+    'L1D vulnerable'		      L1D flushing is disabled
+
+    'L1D conditional cache flushes'   L1D flush is conditionally enabled
+
+    'L1D cache flushes'		      L1D flush is unconditionally enabled
+    ================================  ====================================
+
+The resulting grade of protection is discussed in the following sections.
+
+
+Host mitigation mechanism
+-------------------------
+
+The kernel is unconditionally protected against L1TF attacks from malicious
+user space running on the host.
+
+
+Guest mitigation mechanisms
+---------------------------
+
+.. _l1d_flush:
+
+1. L1D flush on VMENTER
+^^^^^^^^^^^^^^^^^^^^^^^
+
+   To make sure that a guest cannot attack data which is present in the L1D
+   the hypervisor flushes the L1D before entering the guest.
+
+   Flushing the L1D evicts not only the data which should not be accessed
+   by a potentially malicious guest, it also flushes the guest
+   data. Flushing the L1D has a performance impact as the processor has to
+   bring the flushed guest data back into the L1D. Depending on the
+   frequency of VMEXIT/VMENTER and the type of computations in the guest
+   performance degradation in the range of 1% to 50% has been observed. For
+   scenarios where guest VMEXIT/VMENTER are rare the performance impact is
+   minimal. Virtio and mechanisms like posted interrupts are designed to
+   confine the VMEXITs to a bare minimum, but specific configurations and
+   application scenarios might still suffer from a high VMEXIT rate.
+
+   The kernel provides two L1D flush modes:
+    - conditional ('cond')
+    - unconditional ('always')
+
+   The conditional mode avoids L1D flushing after VMEXITs which execute
+   only audited code paths before the corresponding VMENTER. These code
+   paths have been verified that they cannot expose secrets or other
+   interesting data to an attacker, but they can leak information about the
+   address space layout of the hypervisor.
+
+   Unconditional mode flushes L1D on all VMENTER invocations and provides
+   maximum protection. It has a higher overhead than the conditional
+   mode. The overhead cannot be quantified correctly as it depends on the
+   workload scenario and the resulting number of VMEXITs.
+
+   The general recommendation is to enable L1D flush on VMENTER. The kernel
+   defaults to conditional mode on affected processors.
+
+   **Note**, that L1D flush does not prevent the SMT problem because the
+   sibling thread will also bring back its data into the L1D which makes it
+   attackable again.
+
+   L1D flush can be controlled by the administrator via the kernel command
+   line and sysfs control files. See :ref:`mitigation_control_command_line`
+   and :ref:`mitigation_control_kvm`.
+
+.. _guest_confinement:
+
+2. Guest VCPU confinement to dedicated physical cores
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+   To address the SMT problem, it is possible to make a guest or a group of
+   guests affine to one or more physical cores. The proper mechanism for
+   that is to utilize exclusive cpusets to ensure that no other guest or
+   host tasks can run on these cores.
+
+   If only a single guest or related guests run on sibling SMT threads on
+   the same physical core then they can only attack their own memory and
+   restricted parts of the host memory.
+
+   Host memory is attackable, when one of the sibling SMT threads runs in
+   host OS (hypervisor) context and the other in guest context. The amount
+   of valuable information from the host OS context depends on the context
+   which the host OS executes, i.e. interrupts, soft interrupts and kernel
+   threads. The amount of valuable data from these contexts cannot be
+   declared as non-interesting for an attacker without deep inspection of
+   the code.
+
+   **Note**, that assigning guests to a fixed set of physical cores affects
+   the ability of the scheduler to do load balancing and might have
+   negative effects on CPU utilization depending on the hosting
+   scenario. Disabling SMT might be a viable alternative for particular
+   scenarios.
+
+   For further information about confining guests to a single or to a group
+   of cores consult the cpusets documentation:
+
+   https://www.kernel.org/doc/Documentation/cgroup-v1/cpusets.txt
+
+.. _interrupt_isolation:
+
+3. Interrupt affinity
+^^^^^^^^^^^^^^^^^^^^^
+
+   Interrupts can be made affine to logical CPUs. This is not universally
+   true because there are types of interrupts which are truly per CPU
+   interrupts, e.g. the local timer interrupt. Aside of that multi queue
+   devices affine their interrupts to single CPUs or groups of CPUs per
+   queue without allowing the administrator to control the affinities.
+
+   Moving the interrupts, which can be affinity controlled, away from CPUs
+   which run untrusted guests, reduces the attack vector space.
+
+   Whether the interrupts with are affine to CPUs, which run untrusted
+   guests, provide interesting data for an attacker depends on the system
+   configuration and the scenarios which run on the system. While for some
+   of the interrupts it can be assumed that they won't expose interesting
+   information beyond exposing hints about the host OS memory layout, there
+   is no way to make general assumptions.
+
+   Interrupt affinity can be controlled by the administrator via the
+   /proc/irq/$NR/smp_affinity[_list] files. Limited documentation is
+   available at:
+
+   https://www.kernel.org/doc/Documentation/IRQ-affinity.txt
+
+.. _smt_control:
+
+4. SMT control
+^^^^^^^^^^^^^^
+
+   To prevent the SMT issues of L1TF it might be necessary to disable SMT
+   completely. Disabling SMT can have a significant performance impact, but
+   the impact depends on the hosting scenario and the type of workloads.
+   The impact of disabling SMT needs also to be weighted against the impact
+   of other mitigation solutions like confining guests to dedicated cores.
+
+   The kernel provides a sysfs interface to retrieve the status of SMT and
+   to control it. It also provides a kernel command line interface to
+   control SMT.
+
+   The kernel command line interface consists of the following options:
+
+     =========== ==========================================================
+     nosmt	 Affects the bring up of the secondary CPUs during boot. The
+		 kernel tries to bring all present CPUs online during the
+		 boot process. "nosmt" makes sure that from each physical
+		 core only one - the so called primary (hyper) thread is
+		 activated. Due to a design flaw of Intel processors related
+		 to Machine Check Exceptions the non primary siblings have
+		 to be brought up at least partially and are then shut down
+		 again.  "nosmt" can be undone via the sysfs interface.
+
+     nosmt=force Has the same effect as "nosmt" but it does not allow to
+		 undo the SMT disable via the sysfs interface.
+     =========== ==========================================================
+
+   The sysfs interface provides two files:
+
+   - /sys/devices/system/cpu/smt/control
+   - /sys/devices/system/cpu/smt/active
+
+   /sys/devices/system/cpu/smt/control:
+
+     This file allows to read out the SMT control state and provides the
+     ability to disable or (re)enable SMT. The possible states are:
+
+	==============  ===================================================
+	on		SMT is supported by the CPU and enabled. All
+			logical CPUs can be onlined and offlined without
+			restrictions.
+
+	off		SMT is supported by the CPU and disabled. Only
+			the so called primary SMT threads can be onlined
+			and offlined without restrictions. An attempt to
+			online a non-primary sibling is rejected
+
+	forceoff	Same as 'off' but the state cannot be controlled.
+			Attempts to write to the control file are rejected.
+
+	notsupported	The processor does not support SMT. It's therefore
+			not affected by the SMT implications of L1TF.
+			Attempts to write to the control file are rejected.
+	==============  ===================================================
+
+     The possible states which can be written into this file to control SMT
+     state are:
+
+     - on
+     - off
+     - forceoff
+
+   /sys/devices/system/cpu/smt/active:
+
+     This file reports whether SMT is enabled and active, i.e. if on any
+     physical core two or more sibling threads are online.
+
+   SMT control is also possible at boot time via the l1tf kernel command
+   line parameter in combination with L1D flush control. See
+   :ref:`mitigation_control_command_line`.
+
+5. Disabling EPT
+^^^^^^^^^^^^^^^^
+
+  Disabling EPT for virtual machines provides full mitigation for L1TF even
+  with SMT enabled, because the effective page tables for guests are
+  managed and sanitized by the hypervisor. Though disabling EPT has a
+  significant performance impact especially when the Meltdown mitigation
+  KPTI is enabled.
+
+  EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
+
+There is ongoing research and development for new mitigation mechanisms to
+address the performance impact of disabling SMT or EPT.
+
+.. _mitigation_control_command_line:
+
+Mitigation control on the kernel command line
+---------------------------------------------
+
+The kernel command line allows to control the L1TF mitigations at boot
+time with the option "l1tf=". The valid arguments for this option are:
+
+  ============  =============================================================
+  full		Provides all available mitigations for the L1TF
+		vulnerability. Disables SMT and enables all mitigations in
+		the hypervisors, i.e. unconditional L1D flushing
+
+		SMT control and L1D flush control via the sysfs interface
+		is still possible after boot.  Hypervisors will issue a
+		warning when the first VM is started in a potentially
+		insecure configuration, i.e. SMT enabled or L1D flush
+		disabled.
+
+  full,force	Same as 'full', but disables SMT and L1D flush runtime
+		control. Implies the 'nosmt=force' command line option.
+		(i.e. sysfs control of SMT is disabled.)
+
+  flush		Leaves SMT enabled and enables the default hypervisor
+		mitigation, i.e. conditional L1D flushing
+
+		SMT control and L1D flush control via the sysfs interface
+		is still possible after boot.  Hypervisors will issue a
+		warning when the first VM is started in a potentially
+		insecure configuration, i.e. SMT enabled or L1D flush
+		disabled.
+
+  flush,nosmt	Disables SMT and enables the default hypervisor mitigation,
+		i.e. conditional L1D flushing.
+
+		SMT control and L1D flush control via the sysfs interface
+		is still possible after boot.  Hypervisors will issue a
+		warning when the first VM is started in a potentially
+		insecure configuration, i.e. SMT enabled or L1D flush
+		disabled.
+
+  flush,nowarn	Same as 'flush', but hypervisors will not warn when a VM is
+		started in a potentially insecure configuration.
+
+  off		Disables hypervisor mitigations and doesn't emit any
+		warnings.
+		It also drops the swap size and available RAM limit restrictions
+		on both hypervisor and bare metal.
+
+  ============  =============================================================
+
+The default is 'flush'. For details about L1D flushing see :ref:`l1d_flush`.
+
+
+.. _mitigation_control_kvm:
+
+Mitigation control for KVM - module parameter
+-------------------------------------------------------------
+
+The KVM hypervisor mitigation mechanism, flushing the L1D cache when
+entering a guest, can be controlled with a module parameter.
+
+The option/parameter is "kvm-intel.vmentry_l1d_flush=". It takes the
+following arguments:
+
+  ============  ==============================================================
+  always	L1D cache flush on every VMENTER.
+
+  cond		Flush L1D on VMENTER only when the code between VMEXIT and
+		VMENTER can leak host memory which is considered
+		interesting for an attacker. This still can leak host memory
+		which allows e.g. to determine the hosts address space layout.
+
+  never		Disables the mitigation
+  ============  ==============================================================
+
+The parameter can be provided on the kernel command line, as a module
+parameter when loading the modules and at runtime modified via the sysfs
+file:
+
+/sys/module/kvm_intel/parameters/vmentry_l1d_flush
+
+The default is 'cond'. If 'l1tf=full,force' is given on the kernel command
+line, then 'always' is enforced and the kvm-intel.vmentry_l1d_flush
+module parameter is ignored and writes to the sysfs file are rejected.
+
+.. _mitigation_selection:
+
+Mitigation selection guide
+--------------------------
+
+1. No virtualization in use
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+   The system is protected by the kernel unconditionally and no further
+   action is required.
+
+2. Virtualization with trusted guests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+   If the guest comes from a trusted source and the guest OS kernel is
+   guaranteed to have the L1TF mitigations in place the system is fully
+   protected against L1TF and no further action is required.
+
+   To avoid the overhead of the default L1D flushing on VMENTER the
+   administrator can disable the flushing via the kernel command line and
+   sysfs control files. See :ref:`mitigation_control_command_line` and
+   :ref:`mitigation_control_kvm`.
+
+
+3. Virtualization with untrusted guests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+3.1. SMT not supported or disabled
+""""""""""""""""""""""""""""""""""
+
+  If SMT is not supported by the processor or disabled in the BIOS or by
+  the kernel, it's only required to enforce L1D flushing on VMENTER.
+
+  Conditional L1D flushing is the default behaviour and can be tuned. See
+  :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
+
+3.2. EPT not supported or disabled
+""""""""""""""""""""""""""""""""""
+
+  If EPT is not supported by the processor or disabled in the hypervisor,
+  the system is fully protected. SMT can stay enabled and L1D flushing on
+  VMENTER is not required.
+
+  EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
+
+3.3. SMT and EPT supported and active
+"""""""""""""""""""""""""""""""""""""
+
+  If SMT and EPT are supported and active then various degrees of
+  mitigations can be employed:
+
+  - L1D flushing on VMENTER:
+
+    L1D flushing on VMENTER is the minimal protection requirement, but it
+    is only potent in combination with other mitigation methods.
+
+    Conditional L1D flushing is the default behaviour and can be tuned. See
+    :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
+
+  - Guest confinement:
+
+    Confinement of guests to a single or a group of physical cores which
+    are not running any other processes, can reduce the attack surface
+    significantly, but interrupts, soft interrupts and kernel threads can
+    still expose valuable data to a potential attacker. See
+    :ref:`guest_confinement`.
+
+  - Interrupt isolation:
+
+    Isolating the guest CPUs from interrupts can reduce the attack surface
+    further, but still allows a malicious guest to explore a limited amount
+    of host physical memory. This can at least be used to gain knowledge
+    about the host address space layout. The interrupts which have a fixed
+    affinity to the CPUs which run the untrusted guests can depending on
+    the scenario still trigger soft interrupts and schedule kernel threads
+    which might expose valuable information. See
+    :ref:`interrupt_isolation`.
+
+The above three mitigation methods combined can provide protection to a
+certain degree, but the risk of the remaining attack surface has to be
+carefully analyzed. For full protection the following methods are
+available:
+
+  - Disabling SMT:
+
+    Disabling SMT and enforcing the L1D flushing provides the maximum
+    amount of protection. This mitigation is not depending on any of the
+    above mitigation methods.
+
+    SMT control and L1D flushing can be tuned by the command line
+    parameters 'nosmt', 'l1tf', 'kvm-intel.vmentry_l1d_flush' and at run
+    time with the matching sysfs control files. See :ref:`smt_control`,
+    :ref:`mitigation_control_command_line` and
+    :ref:`mitigation_control_kvm`.
+
+  - Disabling EPT:
+
+    Disabling EPT provides the maximum amount of protection as well. It is
+    not depending on any of the above mitigation methods. SMT can stay
+    enabled and L1D flushing is not required, but the performance impact is
+    significant.
+
+    EPT can be disabled in the hypervisor via the 'kvm-intel.ept'
+    parameter.
+
+3.4. Nested virtual machines
+""""""""""""""""""""""""""""
+
+When nested virtualization is in use, three operating systems are involved:
+the bare metal hypervisor, the nested hypervisor and the nested virtual
+machine.  VMENTER operations from the nested hypervisor into the nested
+guest will always be processed by the bare metal hypervisor. If KVM is the
+bare metal hypervisor it will:
+
+ - Flush the L1D cache on every switch from the nested hypervisor to the
+   nested virtual machine, so that the nested hypervisor's secrets are not
+   exposed to the nested virtual machine;
+
+ - Flush the L1D cache on every switch from the nested virtual machine to
+   the nested hypervisor; this is a complex operation, and flushing the L1D
+   cache avoids that the bare metal hypervisor's secrets are exposed to the
+   nested virtual machine;
+
+ - Instruct the nested hypervisor to not perform any L1D cache flush. This
+   is an optimization to avoid double L1D flushing.
+
+
+.. _default_mitigations:
+
+Default mitigations
+-------------------
+
+  The kernel default mitigations for vulnerable processors are:
+
+  - PTE inversion to protect against malicious user space. This is done
+    unconditionally and cannot be controlled. The swap storage is limited
+    to ~16TB.
+
+  - L1D conditional flushing on VMENTER when EPT is enabled for
+    a guest.
+
+  The kernel does not by default enforce the disabling of SMT, which leaves
+  SMT systems vulnerable when running untrusted guests with EPT enabled.
+
+  The rationale for this choice is:
+
+  - Force disabling SMT can break existing setups, especially with
+    unattended updates.
+
+  - If regular users run untrusted guests on their machine, then L1TF is
+    just an add on to other malware which might be embedded in an untrusted
+    guest, e.g. spam-bots or attacks on the local network.
+
+    There is no technical way to prevent a user from running untrusted code
+    on their machines blindly.
+
+  - It's technically extremely unlikely and from today's knowledge even
+    impossible that L1TF can be exploited via the most popular attack
+    mechanisms like JavaScript because these mechanisms have no way to
+    control PTEs. If this would be possible and not other mitigation would
+    be possible, then the default might be different.
+
+  - The administrators of cloud and hosting setups have to carefully
+    analyze the risk for their scenarios and make the appropriate
+    mitigation choices, which might even vary across their deployed
+    machines and also result in other changes of their overall setup.
+    There is no way for the kernel to provide a sensible default for this
+    kind of scenarios.

+MDS - Microarchitectural Data Sampling
+======================================
+
+Microarchitectural Data Sampling is a hardware vulnerability which allows
+unprivileged speculative access to data which is available in various CPU
+internal buffers.
+
+Affected processors
+-------------------
+
+This vulnerability affects a wide range of Intel processors. The
+vulnerability is not present on:
+
+   - Processors from AMD, Centaur and other non Intel vendors
+
+   - Older processor models, where the CPU family is < 6
+
+   - Some Atoms (Bonnell, Saltwell, Goldmont, GoldmontPlus)
+
+   - Intel processors which have the ARCH_CAP_MDS_NO bit set in the
+     IA32_ARCH_CAPABILITIES MSR.
+
+Whether a processor is affected or not can be read out from the MDS
+vulnerability file in sysfs. See :ref:`mds_sys_info`.
+
+Not all processors are affected by all variants of MDS, but the mitigation
+is identical for all of them so the kernel treats them as a single
+vulnerability.
+
+Related CVEs
+------------
+
+The following CVE entries are related to the MDS vulnerability:
+
+   ==============  =====  ===================================================
+   CVE-2018-12126  MSBDS  Microarchitectural Store Buffer Data Sampling
+   CVE-2018-12130  MFBDS  Microarchitectural Fill Buffer Data Sampling
+   CVE-2018-12127  MLPDS  Microarchitectural Load Port Data Sampling
+   CVE-2019-11091  MDSUM  Microarchitectural Data Sampling Uncacheable Memory
+   ==============  =====  ===================================================
+
+Problem
+-------
+
+When performing store, load, L1 refill operations, processors write data
+into temporary microarchitectural structures (buffers). The data in the
+buffer can be forwarded to load operations as an optimization.
+
+Under certain conditions, usually a fault/assist caused by a load
+operation, data unrelated to the load memory address can be speculatively
+forwarded from the buffers. Because the load operation causes a fault or
+assist and its result will be discarded, the forwarded data will not cause
+incorrect program execution or state changes. But a malicious operation
+may be able to forward this speculative data to a disclosure gadget which
+allows in turn to infer the value via a cache side channel attack.
+
+Because the buffers are potentially shared between Hyper-Threads cross
+Hyper-Thread attacks are possible.
+
+Deeper technical information is available in the MDS specific x86
+architecture section: :ref:`Documentation/x86/mds.rst <mds>`.
+
+
+Attack scenarios
+----------------
+
+Attacks against the MDS vulnerabilities can be mounted from malicious non
+priviledged user space applications running on hosts or guest. Malicious
+guest OSes can obviously mount attacks as well.
+
+Contrary to other speculation based vulnerabilities the MDS vulnerability
+does not allow the attacker to control the memory target address. As a
+consequence the attacks are purely sampling based, but as demonstrated with
+the TLBleed attack samples can be postprocessed successfully.
+
+Web-Browsers
+^^^^^^^^^^^^
+
+  It's unclear whether attacks through Web-Browsers are possible at
+  all. The exploitation through Java-Script is considered very unlikely,
+  but other widely used web technologies like Webassembly could possibly be
+  abused.
+
+
+.. _mds_sys_info:
+
+MDS system information
+-----------------------
+
+The Linux kernel provides a sysfs interface to enumerate the current MDS
+status of the system: whether the system is vulnerable, and which
+mitigations are active. The relevant sysfs file is:
+
+/sys/devices/system/cpu/vulnerabilities/mds
+
+The possible values in this file are:
+
+  .. list-table::
+
+     * - 'Not affected'
+       - The processor is not vulnerable
+     * - 'Vulnerable'
+       - The processor is vulnerable, but no mitigation enabled
+     * - 'Vulnerable: Clear CPU buffers attempted, no microcode'
+       - The processor is vulnerable but microcode is not updated.
+
+         The mitigation is enabled on a best effort basis. See :ref:`vmwerv`
+     * - 'Mitigation: Clear CPU buffers'
+       - The processor is vulnerable and the CPU buffer clearing mitigation is
+         enabled.
+
+If the processor is vulnerable then the following information is appended
+to the above information:
+
+    ========================  ============================================
+    'SMT vulnerable'          SMT is enabled
+    'SMT mitigated'           SMT is enabled and mitigated
+    'SMT disabled'            SMT is disabled
+    'SMT Host state unknown'  Kernel runs in a VM, Host SMT state unknown
+    ========================  ============================================
+
+.. _vmwerv:
+
+Best effort mitigation mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  If the processor is vulnerable, but the availability of the microcode based
+  mitigation mechanism is not advertised via CPUID the kernel selects a best
+  effort mitigation mode.  This mode invokes the mitigation instructions
+  without a guarantee that they clear the CPU buffers.
+
+  This is done to address virtualization scenarios where the host has the
+  microcode update applied, but the hypervisor is not yet updated to expose
+  the CPUID to the guest. If the host has updated microcode the protection
+  takes effect otherwise a few cpu cycles are wasted pointlessly.
+
+  The state in the mds sysfs file reflects this situation accordingly.
+
+
+Mitigation mechanism
+-------------------------
+
+The kernel detects the affected CPUs and the presence of the microcode
+which is required.
+
+If a CPU is affected and the microcode is available, then the kernel
+enables the mitigation by default. The mitigation can be controlled at boot
+time via a kernel command line option. See
+:ref:`mds_mitigation_control_command_line`.
+
+.. _cpu_buffer_clear:
+
+CPU buffer clearing
+^^^^^^^^^^^^^^^^^^^
+
+  The mitigation for MDS clears the affected CPU buffers on return to user
+  space and when entering a guest.
+
+  If SMT is enabled it also clears the buffers on idle entry when the CPU
+  is only affected by MSBDS and not any other MDS variant, because the
+  other variants cannot be protected against cross Hyper-Thread attacks.
+
+  For CPUs which are only affected by MSBDS the user space, guest and idle
+  transition mitigations are sufficient and SMT is not affected.
+
+.. _virt_mechanism:
+
+Virtualization mitigation
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  The protection for host to guest transition depends on the L1TF
+  vulnerability of the CPU:
+
+  - CPU is affected by L1TF:
+
+    If the L1D flush mitigation is enabled and up to date microcode is
+    available, the L1D flush mitigation is automatically protecting the
+    guest transition.
+
+    If the L1D flush mitigation is disabled then the MDS mitigation is
+    invoked explicit when the host MDS mitigation is enabled.
+
+    For details on L1TF and virtualization see:
+    :ref:`Documentation/admin-guide/hw-vuln//l1tf.rst <mitigation_control_kvm>`.
+
+  - CPU is not affected by L1TF:
+
+    CPU buffers are flushed before entering the guest when the host MDS
+    mitigation is enabled.
+
+  The resulting MDS protection matrix for the host to guest transition:
+
+  ============ ===== ============= ============ =================
+   L1TF         MDS   VMX-L1FLUSH   Host MDS     MDS-State
+
+   Don't care   No    Don't care    N/A          Not affected
+
+   Yes          Yes   Disabled      Off          Vulnerable
+
+   Yes          Yes   Disabled      Full         Mitigated
+
+   Yes          Yes   Enabled       Don't care   Mitigated
+
+   No           Yes   N/A           Off          Vulnerable
+
+   No           Yes   N/A           Full         Mitigated
+  ============ ===== ============= ============ =================
+
+  This only covers the host to guest transition, i.e. prevents leakage from
+  host to guest, but does not protect the guest internally. Guests need to
+  have their own protections.
+
+.. _xeon_phi:
+
+XEON PHI specific considerations
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  The XEON PHI processor family is affected by MSBDS which can be exploited
+  cross Hyper-Threads when entering idle states. Some XEON PHI variants allow
+  to use MWAIT in user space (Ring 3) which opens an potential attack vector
+  for malicious user space. The exposure can be disabled on the kernel
+  command line with the 'ring3mwait=disable' command line option.
+
+  XEON PHI is not affected by the other MDS variants and MSBDS is mitigated
+  before the CPU enters a idle state. As XEON PHI is not affected by L1TF
+  either disabling SMT is not required for full protection.
+
+.. _mds_smt_control:
+
+SMT control
+^^^^^^^^^^^
+
+  All MDS variants except MSBDS can be attacked cross Hyper-Threads. That
+  means on CPUs which are affected by MFBDS or MLPDS it is necessary to
+  disable SMT for full protection. These are most of the affected CPUs; the
+  exception is XEON PHI, see :ref:`xeon_phi`.
+
+  Disabling SMT can have a significant performance impact, but the impact
+  depends on the type of workloads.
+
+  See the relevant chapter in the L1TF mitigation documentation for details:
+  :ref:`Documentation/admin-guide/hw-vuln/l1tf.rst <smt_control>`.
+
+
+.. _mds_mitigation_control_command_line:
+
+Mitigation control on the kernel command line
+---------------------------------------------
+
+The kernel command line allows to control the MDS mitigations at boot
+time with the option "mds=". The valid arguments for this option are:
+
+  ============  =============================================================
+  full		If the CPU is vulnerable, enable all available mitigations
+		for the MDS vulnerability, CPU buffer clearing on exit to
+		userspace and when entering a VM. Idle transitions are
+		protected as well if SMT is enabled.
+
+		It does not automatically disable SMT.
+
+  full,nosmt	The same as mds=full, with SMT disabled on vulnerable
+		CPUs.  This is the complete mitigation.
+
+  off		Disables MDS mitigations completely.
+
+  ============  =============================================================
+
+Not specifying this option is equivalent to "mds=full".
+
+
+Mitigation selection guide
+--------------------------
+
+1. Trusted userspace
+^^^^^^^^^^^^^^^^^^^^
+
+   If all userspace applications are from a trusted source and do not
+   execute untrusted code which is supplied externally, then the mitigation
+   can be disabled.
+
+
+2. Virtualization with trusted guests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+   The same considerations as above versus trusted user space apply.
+
+3. Virtualization with untrusted guests
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+   The protection depends on the state of the L1TF mitigations.
+   See :ref:`virt_mechanism`.
+
+   If the MDS mitigation is enabled and SMT is disabled, guest to host and
+   guest to guest attacks are prevented.
+
+.. _mds_default_mitigations:
+
+Default mitigations
+-------------------
+
+  The kernel default mitigations for vulnerable processors are:
+
+  - Enable CPU buffer clearing
+
+  The kernel does not by default enforce the disabling of SMT, which leaves
+  SMT systems vulnerable when running untrusted code. The same rationale as
+  for L1TF applies.
+  See :ref:`Documentation/admin-guide/hw-vuln//l1tf.rst <default_mitigations>`.

-L1TF - L1 Terminal Fault
-========================
-
-L1 Terminal Fault is a hardware vulnerability which allows unprivileged
-speculative access to data which is available in the Level 1 Data Cache
-when the page table entry controlling the virtual address, which is used
-for the access, has the Present bit cleared or other reserved bits set.
-
-Affected processors
--------------------
-
-This vulnerability affects a wide range of Intel processors. The
-vulnerability is not present on:
-
-   - Processors from AMD, Centaur and other non Intel vendors
-
-   - Older processor models, where the CPU family is < 6
-
-   - A range of Intel ATOM processors (Cedarview, Cloverview, Lincroft,
-     Penwell, Pineview, Silvermont, Airmont, Merrifield)
-
-   - The Intel XEON PHI family
-
-   - Intel processors which have the ARCH_CAP_RDCL_NO bit set in the
-     IA32_ARCH_CAPABILITIES MSR. If the bit is set the CPU is not affected
-     by the Meltdown vulnerability either. These CPUs should become
-     available by end of 2018.
-
-Whether a processor is affected or not can be read out from the L1TF
-vulnerability file in sysfs. See :ref:`l1tf_sys_info`.
-
-Related CVEs
-------------
-
-The following CVE entries are related to the L1TF vulnerability:
-
-   =============  =================  ==============================
-   CVE-2018-3615  L1 Terminal Fault  SGX related aspects
-   CVE-2018-3620  L1 Terminal Fault  OS, SMM related aspects
-   CVE-2018-3646  L1 Terminal Fault  Virtualization related aspects
-   =============  =================  ==============================
-
-Problem
--------
-
-If an instruction accesses a virtual address for which the relevant page
-table entry (PTE) has the Present bit cleared or other reserved bits set,
-then speculative execution ignores the invalid PTE and loads the referenced
-data if it is present in the Level 1 Data Cache, as if the page referenced
-by the address bits in the PTE was still present and accessible.
-
-While this is a purely speculative mechanism and the instruction will raise
-a page fault when it is retired eventually, the pure act of loading the
-data and making it available to other speculative instructions opens up the
-opportunity for side channel attacks to unprivileged malicious code,
-similar to the Meltdown attack.
-
-While Meltdown breaks the user space to kernel space protection, L1TF
-allows to attack any physical memory address in the system and the attack
-works across all protection domains. It allows an attack of SGX and also
-works from inside virtual machines because the speculation bypasses the
-extended page table (EPT) protection mechanism.
-
-
-Attack scenarios
-----------------
-
-1. Malicious user space
-^^^^^^^^^^^^^^^^^^^^^^^
-
-   Operating Systems store arbitrary information in the address bits of a
-   PTE which is marked non present. This allows a malicious user space
-   application to attack the physical memory to which these PTEs resolve.
-   In some cases user-space can maliciously influence the information
-   encoded in the address bits of the PTE, thus making attacks more
-   deterministic and more practical.
-
-   The Linux kernel contains a mitigation for this attack vector, PTE
-   inversion, which is permanently enabled and has no performance
-   impact. The kernel ensures that the address bits of PTEs, which are not
-   marked present, never point to cacheable physical memory space.
-
-   A system with an up to date kernel is protected against attacks from
-   malicious user space applications.
-
-2. Malicious guest in a virtual machine
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   The fact that L1TF breaks all domain protections allows malicious guest
-   OSes, which can control the PTEs directly, and malicious guest user
-   space applications, which run on an unprotected guest kernel lacking the
-   PTE inversion mitigation for L1TF, to attack physical host memory.
-
-   A special aspect of L1TF in the context of virtualization is symmetric
-   multi threading (SMT). The Intel implementation of SMT is called
-   HyperThreading. The fact that Hyperthreads on the affected processors
-   share the L1 Data Cache (L1D) is important for this. As the flaw allows
-   only to attack data which is present in L1D, a malicious guest running
-   on one Hyperthread can attack the data which is brought into the L1D by
-   the context which runs on the sibling Hyperthread of the same physical
-   core. This context can be host OS, host user space or a different guest.
-
-   If the processor does not support Extended Page Tables, the attack is
-   only possible, when the hypervisor does not sanitize the content of the
-   effective (shadow) page tables.
-
-   While solutions exist to mitigate these attack vectors fully, these
-   mitigations are not enabled by default in the Linux kernel because they
-   can affect performance significantly. The kernel provides several
-   mechanisms which can be utilized to address the problem depending on the
-   deployment scenario. The mitigations, their protection scope and impact
-   are described in the next sections.
-
-   The default mitigations and the rationale for choosing them are explained
-   at the end of this document. See :ref:`default_mitigations`.

-.. _l1tf_sys_info:
-
-L1TF system information
------------------------
-
-The Linux kernel provides a sysfs interface to enumerate the current L1TF
-status of the system: whether the system is vulnerable, and which
-mitigations are active. The relevant sysfs file is:
-
-/sys/devices/system/cpu/vulnerabilities/l1tf
-
-The possible values in this file are:
-
-  ===========================   ===============================
-  'Not affected'		The processor is not vulnerable
-  'Mitigation: PTE Inversion'	The host protection is active
-  ===========================   ===============================
-
-If KVM/VMX is enabled and the processor is vulnerable then the following
-information is appended to the 'Mitigation: PTE Inversion' part:
-
-  - SMT status:
-
-    =====================  ================
-    'VMX: SMT vulnerable'  SMT is enabled
-    'VMX: SMT disabled'    SMT is disabled
-    =====================  ================
-
-  - L1D Flush mode:
-
-    ================================  ====================================
-    'L1D vulnerable'		      L1D flushing is disabled
-
-    'L1D conditional cache flushes'   L1D flush is conditionally enabled
-
-    'L1D cache flushes'		      L1D flush is unconditionally enabled
-    ================================  ====================================
-
-The resulting grade of protection is discussed in the following sections.
-
-
-Host mitigation mechanism
--------------------------
-
-The kernel is unconditionally protected against L1TF attacks from malicious
-user space running on the host.
-
-
-Guest mitigation mechanisms
----------------------------
-
-.. _l1d_flush:
-
-1. L1D flush on VMENTER
-^^^^^^^^^^^^^^^^^^^^^^^
-
-   To make sure that a guest cannot attack data which is present in the L1D
-   the hypervisor flushes the L1D before entering the guest.
-
-   Flushing the L1D evicts not only the data which should not be accessed
-   by a potentially malicious guest, it also flushes the guest
-   data. Flushing the L1D has a performance impact as the processor has to
-   bring the flushed guest data back into the L1D. Depending on the
-   frequency of VMEXIT/VMENTER and the type of computations in the guest
-   performance degradation in the range of 1% to 50% has been observed. For
-   scenarios where guest VMEXIT/VMENTER are rare the performance impact is
-   minimal. Virtio and mechanisms like posted interrupts are designed to
-   confine the VMEXITs to a bare minimum, but specific configurations and
-   application scenarios might still suffer from a high VMEXIT rate.
-
-   The kernel provides two L1D flush modes:
-    - conditional ('cond')
-    - unconditional ('always')
-
-   The conditional mode avoids L1D flushing after VMEXITs which execute
-   only audited code paths before the corresponding VMENTER. These code
-   paths have been verified that they cannot expose secrets or other
-   interesting data to an attacker, but they can leak information about the
-   address space layout of the hypervisor.
-
-   Unconditional mode flushes L1D on all VMENTER invocations and provides
-   maximum protection. It has a higher overhead than the conditional
-   mode. The overhead cannot be quantified correctly as it depends on the
-   workload scenario and the resulting number of VMEXITs.
-
-   The general recommendation is to enable L1D flush on VMENTER. The kernel
-   defaults to conditional mode on affected processors.
-
-   **Note**, that L1D flush does not prevent the SMT problem because the
-   sibling thread will also bring back its data into the L1D which makes it
-   attackable again.
-
-   L1D flush can be controlled by the administrator via the kernel command
-   line and sysfs control files. See :ref:`mitigation_control_command_line`
-   and :ref:`mitigation_control_kvm`.
-
-.. _guest_confinement:
-
-2. Guest VCPU confinement to dedicated physical cores
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   To address the SMT problem, it is possible to make a guest or a group of
-   guests affine to one or more physical cores. The proper mechanism for
-   that is to utilize exclusive cpusets to ensure that no other guest or
-   host tasks can run on these cores.
-
-   If only a single guest or related guests run on sibling SMT threads on
-   the same physical core then they can only attack their own memory and
-   restricted parts of the host memory.
-
-   Host memory is attackable, when one of the sibling SMT threads runs in
-   host OS (hypervisor) context and the other in guest context. The amount
-   of valuable information from the host OS context depends on the context
-   which the host OS executes, i.e. interrupts, soft interrupts and kernel
-   threads. The amount of valuable data from these contexts cannot be
-   declared as non-interesting for an attacker without deep inspection of
-   the code.
-
-   **Note**, that assigning guests to a fixed set of physical cores affects
-   the ability of the scheduler to do load balancing and might have
-   negative effects on CPU utilization depending on the hosting
-   scenario. Disabling SMT might be a viable alternative for particular
-   scenarios.
-
-   For further information about confining guests to a single or to a group
-   of cores consult the cpusets documentation:
-
-   https://www.kernel.org/doc/Documentation/cgroup-v1/cpusets.txt
-
-.. _interrupt_isolation:
-
-3. Interrupt affinity
-^^^^^^^^^^^^^^^^^^^^^
-
-   Interrupts can be made affine to logical CPUs. This is not universally
-   true because there are types of interrupts which are truly per CPU
-   interrupts, e.g. the local timer interrupt. Aside of that multi queue
-   devices affine their interrupts to single CPUs or groups of CPUs per
-   queue without allowing the administrator to control the affinities.
-
-   Moving the interrupts, which can be affinity controlled, away from CPUs
-   which run untrusted guests, reduces the attack vector space.
-
-   Whether the interrupts with are affine to CPUs, which run untrusted
-   guests, provide interesting data for an attacker depends on the system
-   configuration and the scenarios which run on the system. While for some
-   of the interrupts it can be assumed that they won't expose interesting
-   information beyond exposing hints about the host OS memory layout, there
-   is no way to make general assumptions.
-
-   Interrupt affinity can be controlled by the administrator via the
-   /proc/irq/$NR/smp_affinity[_list] files. Limited documentation is
-   available at:
-
-   https://www.kernel.org/doc/Documentation/IRQ-affinity.txt
-
-.. _smt_control:
-
-4. SMT control
-^^^^^^^^^^^^^^
-
-   To prevent the SMT issues of L1TF it might be necessary to disable SMT
-   completely. Disabling SMT can have a significant performance impact, but
-   the impact depends on the hosting scenario and the type of workloads.
-   The impact of disabling SMT needs also to be weighted against the impact
-   of other mitigation solutions like confining guests to dedicated cores.
-
-   The kernel provides a sysfs interface to retrieve the status of SMT and
-   to control it. It also provides a kernel command line interface to
-   control SMT.
-
-   The kernel command line interface consists of the following options:
-
-     =========== ==========================================================
-     nosmt	 Affects the bring up of the secondary CPUs during boot. The
-		 kernel tries to bring all present CPUs online during the
-		 boot process. "nosmt" makes sure that from each physical
-		 core only one - the so called primary (hyper) thread is
-		 activated. Due to a design flaw of Intel processors related
-		 to Machine Check Exceptions the non primary siblings have
-		 to be brought up at least partially and are then shut down
-		 again.  "nosmt" can be undone via the sysfs interface.
-
-     nosmt=force Has the same effect as "nosmt" but it does not allow to
-		 undo the SMT disable via the sysfs interface.
-     =========== ==========================================================
-
-   The sysfs interface provides two files:
-
-   - /sys/devices/system/cpu/smt/control
-   - /sys/devices/system/cpu/smt/active
-
-   /sys/devices/system/cpu/smt/control:
-
-     This file allows to read out the SMT control state and provides the
-     ability to disable or (re)enable SMT. The possible states are:
-
-	==============  ===================================================
-	on		SMT is supported by the CPU and enabled. All
-			logical CPUs can be onlined and offlined without
-			restrictions.
-
-	off		SMT is supported by the CPU and disabled. Only
-			the so called primary SMT threads can be onlined
-			and offlined without restrictions. An attempt to
-			online a non-primary sibling is rejected
-
-	forceoff	Same as 'off' but the state cannot be controlled.
-			Attempts to write to the control file are rejected.
-
-	notsupported	The processor does not support SMT. It's therefore
-			not affected by the SMT implications of L1TF.
-			Attempts to write to the control file are rejected.
-	==============  ===================================================
-
-     The possible states which can be written into this file to control SMT
-     state are:
-
-     - on
-     - off
-     - forceoff
-
-   /sys/devices/system/cpu/smt/active:
-
-     This file reports whether SMT is enabled and active, i.e. if on any
-     physical core two or more sibling threads are online.
-
-   SMT control is also possible at boot time via the l1tf kernel command
-   line parameter in combination with L1D flush control. See
-   :ref:`mitigation_control_command_line`.
-
-5. Disabling EPT
-^^^^^^^^^^^^^^^^
-
-  Disabling EPT for virtual machines provides full mitigation for L1TF even
-  with SMT enabled, because the effective page tables for guests are
-  managed and sanitized by the hypervisor. Though disabling EPT has a
-  significant performance impact especially when the Meltdown mitigation
-  KPTI is enabled.
-
-  EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
-
-There is ongoing research and development for new mitigation mechanisms to
-address the performance impact of disabling SMT or EPT.
-
-.. _mitigation_control_command_line:
-
-Mitigation control on the kernel command line
----------------------------------------------
-
-The kernel command line allows to control the L1TF mitigations at boot
-time with the option "l1tf=". The valid arguments for this option are:
-
-  ============  =============================================================
-  full		Provides all available mitigations for the L1TF
-		vulnerability. Disables SMT and enables all mitigations in
-		the hypervisors, i.e. unconditional L1D flushing
-
-		SMT control and L1D flush control via the sysfs interface
-		is still possible after boot.  Hypervisors will issue a
-		warning when the first VM is started in a potentially
-		insecure configuration, i.e. SMT enabled or L1D flush
-		disabled.
-
-  full,force	Same as 'full', but disables SMT and L1D flush runtime
-		control. Implies the 'nosmt=force' command line option.
-		(i.e. sysfs control of SMT is disabled.)
-
-  flush		Leaves SMT enabled and enables the default hypervisor
-		mitigation, i.e. conditional L1D flushing
-
-		SMT control and L1D flush control via the sysfs interface
-		is still possible after boot.  Hypervisors will issue a
-		warning when the first VM is started in a potentially
-		insecure configuration, i.e. SMT enabled or L1D flush
-		disabled.
-
-  flush,nosmt	Disables SMT and enables the default hypervisor mitigation,
-		i.e. conditional L1D flushing.
-
-		SMT control and L1D flush control via the sysfs interface
-		is still possible after boot.  Hypervisors will issue a
-		warning when the first VM is started in a potentially
-		insecure configuration, i.e. SMT enabled or L1D flush
-		disabled.
-
-  flush,nowarn	Same as 'flush', but hypervisors will not warn when a VM is
-		started in a potentially insecure configuration.
-
-  off		Disables hypervisor mitigations and doesn't emit any
-		warnings.
-		It also drops the swap size and available RAM limit restrictions
-		on both hypervisor and bare metal.
-
-  ============  =============================================================
-
-The default is 'flush'. For details about L1D flushing see :ref:`l1d_flush`.
-
-
-.. _mitigation_control_kvm:
-
-Mitigation control for KVM - module parameter
--------------------------------------------------------------
-
-The KVM hypervisor mitigation mechanism, flushing the L1D cache when
-entering a guest, can be controlled with a module parameter.
-
-The option/parameter is "kvm-intel.vmentry_l1d_flush=". It takes the
-following arguments:
-
-  ============  ==============================================================
-  always	L1D cache flush on every VMENTER.
-
-  cond		Flush L1D on VMENTER only when the code between VMEXIT and
-		VMENTER can leak host memory which is considered
-		interesting for an attacker. This still can leak host memory
-		which allows e.g. to determine the hosts address space layout.
-
-  never		Disables the mitigation
-  ============  ==============================================================
-
-The parameter can be provided on the kernel command line, as a module
-parameter when loading the modules and at runtime modified via the sysfs
-file:
-
-/sys/module/kvm_intel/parameters/vmentry_l1d_flush
-
-The default is 'cond'. If 'l1tf=full,force' is given on the kernel command
-line, then 'always' is enforced and the kvm-intel.vmentry_l1d_flush
-module parameter is ignored and writes to the sysfs file are rejected.
-
-
-Mitigation selection guide
---------------------------
-
-1. No virtualization in use
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   The system is protected by the kernel unconditionally and no further
-   action is required.
-
-2. Virtualization with trusted guests
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   If the guest comes from a trusted source and the guest OS kernel is
-   guaranteed to have the L1TF mitigations in place the system is fully
-   protected against L1TF and no further action is required.
-
-   To avoid the overhead of the default L1D flushing on VMENTER the
-   administrator can disable the flushing via the kernel command line and
-   sysfs control files. See :ref:`mitigation_control_command_line` and
-   :ref:`mitigation_control_kvm`.
-
-
-3. Virtualization with untrusted guests
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-3.1. SMT not supported or disabled
-""""""""""""""""""""""""""""""""""
-
-  If SMT is not supported by the processor or disabled in the BIOS or by
-  the kernel, it's only required to enforce L1D flushing on VMENTER.
-
-  Conditional L1D flushing is the default behaviour and can be tuned. See
-  :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
-
-3.2. EPT not supported or disabled
-""""""""""""""""""""""""""""""""""
-
-  If EPT is not supported by the processor or disabled in the hypervisor,
-  the system is fully protected. SMT can stay enabled and L1D flushing on
-  VMENTER is not required.
-
-  EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
-
-3.3. SMT and EPT supported and active
-"""""""""""""""""""""""""""""""""""""
-
-  If SMT and EPT are supported and active then various degrees of
-  mitigations can be employed:
-
-  - L1D flushing on VMENTER:
-
-    L1D flushing on VMENTER is the minimal protection requirement, but it
-    is only potent in combination with other mitigation methods.
-
-    Conditional L1D flushing is the default behaviour and can be tuned. See
-    :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
-
-  - Guest confinement:
-
-    Confinement of guests to a single or a group of physical cores which
-    are not running any other processes, can reduce the attack surface
-    significantly, but interrupts, soft interrupts and kernel threads can
-    still expose valuable data to a potential attacker. See
-    :ref:`guest_confinement`.
-
-  - Interrupt isolation:
-
-    Isolating the guest CPUs from interrupts can reduce the attack surface
-    further, but still allows a malicious guest to explore a limited amount
-    of host physical memory. This can at least be used to gain knowledge
-    about the host address space layout. The interrupts which have a fixed
-    affinity to the CPUs which run the untrusted guests can depending on
-    the scenario still trigger soft interrupts and schedule kernel threads
-    which might expose valuable information. See
-    :ref:`interrupt_isolation`.
-
-The above three mitigation methods combined can provide protection to a
-certain degree, but the risk of the remaining attack surface has to be
-carefully analyzed. For full protection the following methods are
-available:
-
-  - Disabling SMT:
-
-    Disabling SMT and enforcing the L1D flushing provides the maximum
-    amount of protection. This mitigation is not depending on any of the
-    above mitigation methods.
-
-    SMT control and L1D flushing can be tuned by the command line
-    parameters 'nosmt', 'l1tf', 'kvm-intel.vmentry_l1d_flush' and at run
-    time with the matching sysfs control files. See :ref:`smt_control`,
-    :ref:`mitigation_control_command_line` and
-    :ref:`mitigation_control_kvm`.
-
-  - Disabling EPT:
-
-    Disabling EPT provides the maximum amount of protection as well. It is
-    not depending on any of the above mitigation methods. SMT can stay
-    enabled and L1D flushing is not required, but the performance impact is
-    significant.
-
-    EPT can be disabled in the hypervisor via the 'kvm-intel.ept'
-    parameter.
-
-3.4. Nested virtual machines
-""""""""""""""""""""""""""""
-
-When nested virtualization is in use, three operating systems are involved:
-the bare metal hypervisor, the nested hypervisor and the nested virtual
-machine.  VMENTER operations from the nested hypervisor into the nested
-guest will always be processed by the bare metal hypervisor. If KVM is the
-bare metal hypervisor it will:
-
- - Flush the L1D cache on every switch from the nested hypervisor to the
-   nested virtual machine, so that the nested hypervisor's secrets are not
-   exposed to the nested virtual machine;
-
- - Flush the L1D cache on every switch from the nested virtual machine to
-   the nested hypervisor; this is a complex operation, and flushing the L1D
-   cache avoids that the bare metal hypervisor's secrets are exposed to the
-   nested virtual machine;
-
- - Instruct the nested hypervisor to not perform any L1D cache flush. This
-   is an optimization to avoid double L1D flushing.
-
-
-.. _default_mitigations:
-
-Default mitigations
--------------------
-
-  The kernel default mitigations for vulnerable processors are:
-
-  - PTE inversion to protect against malicious user space. This is done
-    unconditionally and cannot be controlled. The swap storage is limited
-    to ~16TB.
-
-  - L1D conditional flushing on VMENTER when EPT is enabled for
-    a guest.
-
-  The kernel does not by default enforce the disabling of SMT, which leaves
-  SMT systems vulnerable when running untrusted guests with EPT enabled.
-
-  The rationale for this choice is:
-
-  - Force disabling SMT can break existing setups, especially with
-    unattended updates.
-
-  - If regular users run untrusted guests on their machine, then L1TF is
-    just an add on to other malware which might be embedded in an untrusted
-    guest, e.g. spam-bots or attacks on the local network.
-
-    There is no technical way to prevent a user from running untrusted code
-    on their machines blindly.
-
-  - It's technically extremely unlikely and from today's knowledge even
-    impossible that L1TF can be exploited via the most popular attack
-    mechanisms like JavaScript because these mechanisms have no way to
-    control PTEs. If this would be possible and not other mitigation would
-    be possible, then the default might be different.
-
-  - The administrators of cloud and hosting setups have to carefully
-    analyze the risk for their scenarios and make the appropriate
-    mitigation choices, which might even vary across their deployed
-    machines and also result in other changes of their overall setup.
-    There is no way for the kernel to provide a sensible default for this
-    kind of scenarios.

+=============
+NUMA Locality
+=============
+
+Some platforms may have multiple types of memory attached to a compute
+node. These disparate memory ranges may share some characteristics, such
+as CPU cache coherence, but may have different performance. For example,
+different media types and buses affect bandwidth and latency.
+
+A system supports such heterogeneous memory by grouping each memory type
+under different domains, or "nodes", based on locality and performance
+characteristics.  Some memory may share the same node as a CPU, and others
+are provided as memory only nodes. While memory only nodes do not provide
+CPUs, they may still be local to one or more compute nodes relative to
+other nodes. The following diagram shows one such example of two compute
+nodes with local memory and a memory only node for each of compute node::
+
+ +------------------+     +------------------+
+ | Compute Node 0   +-----+ Compute Node 1   |
+ | Local Node0 Mem  |     | Local Node1 Mem  |
+ +--------+---------+     +--------+---------+
+          |                        |
+ +--------+---------+     +--------+---------+
+ | Slower Node2 Mem |     | Slower Node3 Mem |
+ +------------------+     +--------+---------+
+
+A "memory initiator" is a node containing one or more devices such as
+CPUs or separate memory I/O devices that can initiate memory requests.
+A "memory target" is a node containing one or more physical address
+ranges accessible from one or more memory initiators.
+
+When multiple memory initiators exist, they may not all have the same
+performance when accessing a given memory target. Each initiator-target
+pair may be organized into different ranked access classes to represent
+this relationship. The highest performing initiator to a given target
+is considered to be one of that target's local initiators, and given
+the highest access class, 0. Any given target may have one or more
+local initiators, and any given initiator may have multiple local
+memory targets.
+
+To aid applications matching memory targets with their initiators, the
+kernel provides symlinks to each other. The following example lists the
+relationship for the access class "0" memory initiators and targets::
+
+	# symlinks -v /sys/devices/system/node/nodeX/access0/targets/
+	relative: /sys/devices/system/node/nodeX/access0/targets/nodeY -> ../../nodeY
+
+	# symlinks -v /sys/devices/system/node/nodeY/access0/initiators/
+	relative: /sys/devices/system/node/nodeY/access0/initiators/nodeX -> ../../nodeX
+
+A memory initiator may have multiple memory targets in the same access
+class. The target memory's initiators in a given class indicate the
+nodes' access characteristics share the same performance relative to other
+linked initiator nodes. Each target within an initiator's access class,
+though, do not necessarily perform the same as each other.
+
+================
+NUMA Performance
+================
+
+Applications may wish to consider which node they want their memory to
+be allocated from based on the node's performance characteristics. If
+the system provides these attributes, the kernel exports them under the
+node sysfs hierarchy by appending the attributes directory under the
+memory node's access class 0 initiators as follows::
+
+	/sys/devices/system/node/nodeY/access0/initiators/
+
+These attributes apply only when accessed from nodes that have the
+are linked under the this access's inititiators.
+
+The performance characteristics the kernel provides for the local initiators
+are exported are as follows::
+
+	# tree -P "read*|write*" /sys/devices/system/node/nodeY/access0/initiators/
+	/sys/devices/system/node/nodeY/access0/initiators/
+	|-- read_bandwidth
+	|-- read_latency
+	|-- write_bandwidth
+	`-- write_latency
+
+The bandwidth attributes are provided in MiB/second.
+
+The latency attributes are provided in nanoseconds.
+
+The values reported here correspond to the rated latency and bandwidth
+for the platform.
+
+==========
+NUMA Cache
+==========
+
+System memory may be constructed in a hierarchy of elements with various
+performance characteristics in order to provide large address space of
+slower performing memory cached by a smaller higher performing memory. The
+system physical addresses memory  initiators are aware of are provided
+by the last memory level in the hierarchy. The system meanwhile uses
+higher performing memory to transparently cache access to progressively
+slower levels.
+
+The term "far memory" is used to denote the last level memory in the
+hierarchy. Each increasing cache level provides higher performing
+initiator access, and the term "near memory" represents the fastest
+cache provided by the system.
+
+This numbering is different than CPU caches where the cache level (ex:
+L1, L2, L3) uses the CPU-side view where each increased level is lower
+performing. In contrast, the memory cache level is centric to the last
+level memory, so the higher numbered cache level corresponds to  memory
+nearer to the CPU, and further from far memory.
+
+The memory-side caches are not directly addressable by software. When
+software accesses a system address, the system will return it from the
+near memory cache if it is present. If it is not present, the system
+accesses the next level of memory until there is either a hit in that
+cache level, or it reaches far memory.
+
+An application does not need to know about caching attributes in order
+to use the system. Software may optionally query the memory cache
+attributes in order to maximize the performance out of such a setup.
+If the system provides a way for the kernel to discover this information,
+for example with ACPI HMAT (Heterogeneous Memory Attribute Table),
+the kernel will append these attributes to the NUMA node memory target.
+
+When the kernel first registers a memory cache with a node, the kernel
+will create the following directory::
+
+	/sys/devices/system/node/nodeX/memory_side_cache/
+
+If that directory is not present, the system either does not not provide
+a memory-side cache, or that information is not accessible to the kernel.
+
+The attributes for each level of cache is provided under its cache
+level index::
+
+	/sys/devices/system/node/nodeX/memory_side_cache/indexA/
+	/sys/devices/system/node/nodeX/memory_side_cache/indexB/
+	/sys/devices/system/node/nodeX/memory_side_cache/indexC/
+
+Each cache level's directory provides its attributes. For example, the
+following shows a single cache level and the attributes available for
+software to query::
+
+	# tree sys/devices/system/node/node0/memory_side_cache/
+	/sys/devices/system/node/node0/memory_side_cache/
+	|-- index1
+	|   |-- indexing
+	|   |-- line_size
+	|   |-- size
+	|   `-- write_policy
+
+The "indexing" will be 0 if it is a direct-mapped cache, and non-zero
+for any other indexed based, multi-way associativity.
+
+The "line_size" is the number of bytes accessed from the next cache
+level on a miss.
+
+The "size" is the number of bytes provided by this cache level.
+
+The "write_policy" will be 0 for write-back, and non-zero for
+write-through caching.

+Intel Performance and Energy Bias Attribute in ``sysfs``
+========================================================
+
+The Intel Performance and Energy Bias Hint (EPB) value for a given (logical) CPU
+can be checked or updated through a ``sysfs`` attribute (file) under
+:file:`/sys/devices/system/cpu/cpu<N>/power/`, where the CPU number ``<N>``
+is allocated at the system initialization time:
+
+``energy_perf_bias``
+	Shows the current EPB value for the CPU in a sliding scale 0 - 15, where
+	a value of 0 corresponds to a hint preference for highest performance
+	and a value of 15 corresponds to the maximum energy savings.
+
+	In order to update the EPB value for the CPU, this attribute can be
+	written to, either with a number in the 0 - 15 sliding scale above, or
+	with one of the strings: "performance", "balance-performance", "normal",
+	"balance-power", "power" that represent values reflected by their
+	meaning.
+
+	This attribute is present for all online CPUs supporting the EPB
+	feature.
+
+Note that while the EPB interface to the processor is defined at the logical CPU
+level, the physical register backing it may be shared by multiple CPUs (for
+example, SMT siblings or cores in one package).  For this reason, updating the
+EPB value for one CPU may cause the EPB values for other CPUs to change.

+Perf Event Attributes
+=====================
+
+Author: Andrew Murray <andrew.murray@arm.com>
+Date: 2019-03-06
+
+exclude_user
+------------
+
+This attribute excludes userspace.
+
+Userspace always runs at EL0 and thus this attribute will exclude EL0.
+
+
+exclude_kernel
+--------------
+
+This attribute excludes the kernel.
+
+The kernel runs at EL2 with VHE and EL1 without. Guest kernels always run
+at EL1.
+
+For the host this attribute will exclude EL1 and additionally EL2 on a VHE
+system.
+
+For the guest this attribute will exclude EL1. Please note that EL2 is
+never counted within a guest.
+
+
+exclude_hv
+----------
+
+This attribute excludes the hypervisor.
+
+For a VHE host this attribute is ignored as we consider the host kernel to
+be the hypervisor.
+
+For a non-VHE host this attribute will exclude EL2 as we consider the
+hypervisor to be any code that runs at EL2 which is predominantly used for
+guest/host transitions.
+
+For the guest this attribute has no effect. Please note that EL2 is
+never counted within a guest.
+
+
+exclude_host / exclude_guest
+----------------------------
+
+These attributes exclude the KVM host and guest, respectively.
+
+The KVM host may run at EL0 (userspace), EL1 (non-VHE kernel) and EL2 (VHE
+kernel or non-VHE hypervisor).
+
+The KVM guest may run at EL0 (userspace) and EL1 (kernel).
+
+Due to the overlapping exception levels between host and guests we cannot
+exclusively rely on the PMU's hardware exception filtering - therefore we
+must enable/disable counting on the entry and exit to the guest. This is
+performed differently on VHE and non-VHE systems.
+
+For non-VHE systems we exclude EL2 for exclude_host - upon entering and
+exiting the guest we disable/enable the event as appropriate based on the
+exclude_host and exclude_guest attributes.
+
+For VHE systems we exclude EL1 for exclude_guest and exclude both EL0,EL2
+for exclude_host. Upon entering and exiting the guest we modify the event
+to include/exclude EL0 as appropriate based on the exclude_host and
+exclude_guest attributes.
+
+The statements above also apply when these attributes are used within a
+non-VHE guest however please note that EL2 is never counted within a guest.
+
+
+Accuracy
+--------
+

-Pointer authentication is not currently supported in KVM guests. KVM
-will mask the feature bits from ID_AA64ISAR1_EL1, and attempted use of
-the feature will result in an UNDEFINED exception being injected into
-the guest.
+Pointer authentication is enabled in KVM guest when each virtual cpu is
+initialised by passing flags KVM_ARM_VCPU_PTRAUTH_[ADDRESS/GENERIC] and
+requesting these two separate cpu features to be enabled. The current KVM
+guest implementation works by enabling both features together, so both
+these userspace flags are checked before enabling pointer authentication.
+The separate userspace flag will allow to have no userspace ABI changes
+if support is added in the future to allow these two features to be
+enabled independently of one another.
+
+As Arm Architecture specifies that Pointer Authentication feature is
+implemented along with the VHE feature so KVM arm64 ptrauth code relies
+on VHE mode to be present.
+
+Additionally, when these vcpu feature flags are not set then KVM will
+filter out the Pointer Authentication system key registers from
+KVM_GET/SET_REG_* ioctls and mask those features from cpufeature ID
+register. Any attempt to use the Pointer Authentication instructions will
+result in an UNDEFINED exception being injected into the guest.

+support bounded loops.
+
+Q: What are the verifier limits?
+--------------------------------
+A: The only limit known to the user space is BPF_MAXINSNS (4096).
+It's the maximum number of instructions that the unprivileged bpf
+program can have. The verifier has various internal limits.
+Like the maximum number of instructions that can be explored during
+program analysis. Currently, that limit is set to 1 million.
+Which essentially means that the largest program can consist
+of 1 million NOP instructions. There is a limit to the maximum number
+of subsequent branches, a limit to the number of nested bpf-to-bpf
+calls, a limit to the number of the verifier states per instruction,
+a limit to the number of maps used by the program.
+All these limits can be hit with a sufficiently complex program.
+There are also non-numerical limits that can cause the program
+to be rejected. The verifier used to recognize only pointer + constant
+expressions. Now it can recognize pointer + bounded_register.
+bpf_lookup_map_elem(key) had a requirement that 'key' must be
+a pointer to the stack. Now, 'key' can be a pointer to map value.
+The verifier is steadily getting 'smarter'. The limits are
+being removed. The only way to know that the program is going to
+be accepted by the verifier is to try to load it.
+The bpf development process guarantees that the future kernel
+versions will accept all bpf programs that were accepted by
+the earlier versions.

+===========================
+BPF_PROG_TYPE_CGROUP_SYSCTL
+===========================
+
+This document describes ``BPF_PROG_TYPE_CGROUP_SYSCTL`` program type that
+provides cgroup-bpf hook for sysctl.
+
+The hook has to be attached to a cgroup and will be called every time a
+process inside that cgroup tries to read from or write to sysctl knob in proc.
+
+1. Attach type
+**************
+
+``BPF_CGROUP_SYSCTL`` attach type has to be used to attach
+``BPF_PROG_TYPE_CGROUP_SYSCTL`` program to a cgroup.
+
+2. Context
+**********
+
+``BPF_PROG_TYPE_CGROUP_SYSCTL`` provides access to the following context from
+BPF program::
+
+    struct bpf_sysctl {
+        __u32 write;
+        __u32 file_pos;
+    };
+
+* ``write`` indicates whether sysctl value is being read (``0``) or written
+  (``1``). This field is read-only.
+
+* ``file_pos`` indicates file position sysctl is being accessed at, read
+  or written. This field is read-write. Writing to the field sets the starting
+  position in sysctl proc file ``read(2)`` will be reading from or ``write(2)``
+  will be writing to. Writing zero to the field can be used e.g. to override
+  whole sysctl value by ``bpf_sysctl_set_new_value()`` on ``write(2)`` even
+  when it's called by user space on ``file_pos > 0``. Writing non-zero
+  value to the field can be used to access part of sysctl value starting from
+  specified ``file_pos``. Not all sysctl support access with ``file_pos !=
+  0``, e.g. writes to numeric sysctl entries must always be at file position
+  ``0``. See also ``kernel.sysctl_writes_strict`` sysctl.
+
+See `linux/bpf.h`_ for more details on how context field can be accessed.
+
+3. Return code
+**************
+
+``BPF_PROG_TYPE_CGROUP_SYSCTL`` program must return one of the following
+return codes:
+
+* ``0`` means "reject access to sysctl";
+* ``1`` means "proceed with access".
+
+If program returns ``0`` user space will get ``-1`` from ``read(2)`` or
+``write(2)`` and ``errno`` will be set to ``EPERM``.
+
+4. Helpers
+**********
+
+Since sysctl knob is represented by a name and a value, sysctl specific BPF
+helpers focus on providing access to these properties:
+
+* ``bpf_sysctl_get_name()`` to get sysctl name as it is visible in
+  ``/proc/sys`` into provided by BPF program buffer;
+
+* ``bpf_sysctl_get_current_value()`` to get string value currently held by
+  sysctl into provided by BPF program buffer. This helper is available on both
+  ``read(2)`` from and ``write(2)`` to sysctl;
+
+* ``bpf_sysctl_get_new_value()`` to get new string value currently being
+  written to sysctl before actual write happens. This helper can be used only
+  on ``ctx->write == 1``;
+
+* ``bpf_sysctl_set_new_value()`` to override new string value currently being
+  written to sysctl before actual write happens. Sysctl value will be
+  overridden starting from the current ``ctx->file_pos``. If the whole value
+  has to be overridden BPF program can set ``file_pos`` to zero before calling
+  to the helper. This helper can be used only on ``ctx->write == 1``. New
+  string value set by the helper is treated and verified by kernel same way as
+  an equivalent string passed by user space.
+
+BPF program sees sysctl value same way as user space does in proc filesystem,
+i.e. as a string. Since many sysctl values represent an integer or a vector
+of integers, the following helpers can be used to get numeric value from the
+string:
+
+* ``bpf_strtol()`` to convert initial part of the string to long integer
+  similar to user space `strtol(3)`_;
+* ``bpf_strtoul()`` to convert initial part of the string to unsigned long
+  integer similar to user space `strtoul(3)`_;
+
+See `linux/bpf.h`_ for more details on helpers described here.
+
+5. Examples
+***********
+
+See `test_sysctl_prog.c`_ for an example of BPF program in C that access
+sysctl name and value, parses string value to get vector of integers and uses
+the result to make decision whether to allow or deny access to sysctl.
+
+6. Notes
+********
+
+``BPF_PROG_TYPE_CGROUP_SYSCTL`` is intended to be used in **trusted** root
+environment, for example to monitor sysctl usage or catch unreasonable values
+an application, running as root in a separate cgroup, is trying to set.
+
+Since `task_dfl_cgroup(current)` is called at `sys_read` / `sys_write` time it
+may return results different from that at `sys_open` time, i.e. process that
+opened sysctl file in proc filesystem may differ from process that is trying
+to read from / write to it and two such processes may run in different
+cgroups, what means ``BPF_PROG_TYPE_CGROUP_SYSCTL`` should not be used as a
+security mechanism to limit sysctl usage.
+
+As with any cgroup-bpf program additional care should be taken if an
+application running as root in a cgroup should not be allowed to
+detach/replace BPF program attached by administrator.

+============================
+BPF_PROG_TYPE_FLOW_DISSECTOR
+============================
+
+Overview
+========
+
+Flow dissector is a routine that parses metadata out of the packets. It's
+used in the various places in the networking subsystem (RFS, flow hash, etc).
+
+BPF flow dissector is an attempt to reimplement C-based flow dissector logic
+in BPF to gain all the benefits of BPF verifier (namely, limits on the
+number of instructions and tail calls).
+
+API
+===
+
+BPF flow dissector programs operate on an ``__sk_buff``. However, only the
+limited set of fields is allowed: ``data``, ``data_end`` and ``flow_keys``.
+``flow_keys`` is ``struct bpf_flow_keys`` and contains flow dissector input
+and output arguments.
+
+The inputs are:
+  * ``nhoff`` - initial offset of the networking header
+  * ``thoff`` - initial offset of the transport header, initialized to nhoff
+  * ``n_proto`` - L3 protocol type, parsed out of L2 header
+
+Flow dissector BPF program should fill out the rest of the ``struct
+bpf_flow_keys`` fields. Input arguments ``nhoff/thoff/n_proto`` should be
+also adjusted accordingly.
+
+The return code of the BPF program is either BPF_OK to indicate successful
+dissection, or BPF_DROP to indicate parsing error.
+
+__sk_buff->data
+===============
+
+In the VLAN-less case, this is what the initial state of the BPF flow
+dissector looks like::
+
+  +------+------+------------+-----------+
+  | DMAC | SMAC | ETHER_TYPE | L3_HEADER |
+  +------+------+------------+-----------+
+                              ^
+                              |
+                              +-- flow dissector starts here
+
+
+.. code:: c
+
+  skb->data + flow_keys->nhoff point to the first byte of L3_HEADER
+  flow_keys->thoff = nhoff
+  flow_keys->n_proto = ETHER_TYPE
+
+In case of VLAN, flow dissector can be called with the two different states.
+
+Pre-VLAN parsing::
+
+  +------+------+------+-----+-----------+-----------+
+  | DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
+  +------+------+------+-----+-----------+-----------+
+                        ^
+                        |
+                        +-- flow dissector starts here
+
+.. code:: c
+
+  skb->data + flow_keys->nhoff point the to first byte of TCI
+  flow_keys->thoff = nhoff
+  flow_keys->n_proto = TPID
+
+Please note that TPID can be 802.1AD and, hence, BPF program would
+have to parse VLAN information twice for double tagged packets.
+
+
+Post-VLAN parsing::
+
+  +------+------+------+-----+-----------+-----------+
+  | DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
+  +------+------+------+-----+-----------+-----------+
+                                          ^
+                                          |
+                                          +-- flow dissector starts here
+
+.. code:: c
+
+  skb->data + flow_keys->nhoff point the to first byte of L3_HEADER
+  flow_keys->thoff = nhoff
+  flow_keys->n_proto = ETHER_TYPE
+
+In this case VLAN information has been processed before the flow dissector
+and BPF flow dissector is not required to handle it.
+
+
+The takeaway here is as follows: BPF flow dissector program can be called with
+the optional VLAN header and should gracefully handle both cases: when single
+or double VLAN is present and when it is not present. The same program
+can be called for both cases and would have to be written carefully to
+handle both cases.
+
+
+Reference Implementation
+========================
+
+See ``tools/testing/selftests/bpf/progs/bpf_flow.c`` for the reference
+implementation and ``tools/testing/selftests/bpf/flow_dissector_load.[hc]``
+for the loader. bpftool can be used to load BPF flow dissector program as well.
+
+The reference implementation is organized as follows:
+  * ``jmp_table`` map that contains sub-programs for each supported L3 protocol
+  * ``_dissect`` routine - entry point; it does input ``n_proto`` parsing and
+    does ``bpf_tail_call`` to the appropriate L3 handler
+
+Since BPF at this point doesn't support looping (or any jumping back),
+jmp_table is used instead to handle multiple levels of encapsulation (and
+IPv6 options).
+
+
+Current Limitations
+===================
+BPF flow dissector doesn't support exporting all the metadata that in-kernel
+C-based implementation can export. Notable example is single VLAN (802.1Q)
+and double VLAN (802.1AD) tags. Please refer to the ``struct bpf_flow_keys``
+for a set of information that's currently can be exported from the BPF context.

-- Enable group scheduling in CFQ
-	CONFIG_CFQ_GROUP_IOSCHED=y

-	mkdir /sys/fs/cgroup/blkio
-	mount -t cgroup -o blkio none /sys/fs/cgroup/blkio
-
-- Create two cgroups
-	mkdir -p /sys/fs/cgroup/blkio/test1/ /sys/fs/cgroup/blkio/test2
-
-- Set weights of group test1 and test2
-	echo 1000 > /sys/fs/cgroup/blkio/test1/blkio.weight
-	echo 500 > /sys/fs/cgroup/blkio/test2/blkio.weight
-
-- Create two same size files (say 512MB each) on same disk (file1, file2) and
-  launch two dd threads in different cgroup to read those files.
-
-	sync
-	echo 3 > /proc/sys/vm/drop_caches
-
-	dd if=/mnt/sdb/zerofile1 of=/dev/null &
-	echo $! > /sys/fs/cgroup/blkio/test1/tasks
-	cat /sys/fs/cgroup/blkio/test1/tasks
-
-	dd if=/mnt/sdb/zerofile2 of=/dev/null &
-	echo $! > /sys/fs/cgroup/blkio/test2/tasks
-	cat /sys/fs/cgroup/blkio/test2/tasks
-
-- At macro level, first dd should finish first. To get more precise data, keep
-  on looking at (with the help of script), at blkio.disk_time and
-  blkio.disk_sectors files of both test1 and test2 groups. This will tell how
-  much disk time (in milliseconds), each group got and how many sectors each
-  group dispatched to the disk. We provide fairness in terms of disk time, so

-=================
-/sys/block/<disk>/queue/iosched/slice_idle
-------------------------------------------
-On a faster hardware CFQ can be slow, especially with sequential workload.
-This happens because CFQ idles on a single queue and single queue might not
-drive deeper request queue depths to keep the storage busy. In such scenarios
-one can try setting slice_idle=0 and that would switch CFQ to IOPS
-(IO operations per second) mode on NCQ supporting hardware.
-
-That means CFQ will not idle between cfq queues of a cfq group and hence be
-able to driver higher queue depth and achieve better throughput. That also
-means that cfq provides fairness among groups in terms of IOPS and not in
-terms of disk time.
-
-/sys/block/<disk>/queue/iosched/group_idle
-------------------------------------------
-If one disables idling on individual cfq queues and cfq service trees by
-setting slice_idle=0, group_idle kicks in. That means CFQ will still idle
-on the group in an attempt to provide fairness among groups.
-
-By default group_idle is same as slice_idle and does not do anything if
-slice_idle is enabled.
-
-One can experience an overall throughput drop if you have created multiple
-groups and put applications in that group which are not driving enough
-IO to keep disk busy. In that case set group_idle=0, and CFQ will not idle
-on individual groups and throughput should improve.

+dm-dust
+=======
+
+This target emulates the behavior of bad sectors at arbitrary
+locations, and the ability to enable the emulation of the failures
+at an arbitrary time.
+
+This target behaves similarly to a linear target.  At a given time,
+the user can send a message to the target to start failing read
+requests on specific blocks (to emulate the behavior of a hard disk
+drive with bad sectors).
+
+When the failure behavior is enabled (i.e.: when the output of
+"dmsetup status" displays "fail_read_on_bad_block"), reads of blocks
+in the "bad block list" will fail with EIO ("Input/output error").
+
+Writes of blocks in the "bad block list will result in the following:
+
+1. Remove the block from the "bad block list".
+2. Successfully complete the write.
+
+This emulates the "remapped sector" behavior of a drive with bad
+sectors.
+
+Normally, a drive that is encountering bad sectors will most likely
+encounter more bad sectors, at an unknown time or location.
+With dm-dust, the user can use the "addbadblock" and "removebadblock"
+messages to add arbitrary bad blocks at new locations, and the
+"enable" and "disable" messages to modulate the state of whether the
+configured "bad blocks" will be treated as bad, or bypassed.
+This allows the pre-writing of test data and metadata prior to
+simulating a "failure" event where bad sectors start to appear.
+
+Table parameters:
+-----------------
+<device_path> <offset> <blksz>
+
+Mandatory parameters:
+    <device_path>: path to the block device.
+    <offset>: offset to data area from start of device_path
+    <blksz>: block size in bytes
+	     (minimum 512, maximum 1073741824, must be a power of 2)
+
+Usage instructions:
+-------------------
+
+First, find the size (in 512-byte sectors) of the device to be used:
+
+$ sudo blockdev --getsz /dev/vdb1
+33552384
+
+Create the dm-dust device:
+(For a device with a block size of 512 bytes)
+$ sudo dmsetup create dust1 --table '0 33552384 dust /dev/vdb1 0 512'
+
+(For a device with a block size of 4096 bytes)
+$ sudo dmsetup create dust1 --table '0 33552384 dust /dev/vdb1 0 4096'
+
+Check the status of the read behavior ("bypass" indicates that all I/O
+will be passed through to the underlying device):
+$ sudo dmsetup status dust1
+0 33552384 dust 252:17 bypass
+
+$ sudo dd if=/dev/mapper/dust1 of=/dev/null bs=512 count=128 iflag=direct
+128+0 records in
+128+0 records out
+
+$ sudo dd if=/dev/zero of=/dev/mapper/dust1 bs=512 count=128 oflag=direct
+128+0 records in
+128+0 records out
+
+Adding and removing bad blocks:
+-------------------------------
+
+At any time (i.e.: whether the device has the "bad block" emulation
+enabled or disabled), bad blocks may be added or removed from the
+device via the "addbadblock" and "removebadblock" messages:
+
+$ sudo dmsetup message dust1 0 addbadblock 60
+kernel: device-mapper: dust: badblock added at block 60
+
+$ sudo dmsetup message dust1 0 addbadblock 67
+kernel: device-mapper: dust: badblock added at block 67
+
+$ sudo dmsetup message dust1 0 addbadblock 72
+kernel: device-mapper: dust: badblock added at block 72
+
+These bad blocks will be stored in the "bad block list".
+While the device is in "bypass" mode, reads and writes will succeed:
+
+$ sudo dmsetup status dust1
+0 33552384 dust 252:17 bypass
+
+Enabling block read failures:
+-----------------------------
+
+To enable the "fail read on bad block" behavior, send the "enable" message:
+
+$ sudo dmsetup message dust1 0 enable
+kernel: device-mapper: dust: enabling read failures on bad sectors
+
+$ sudo dmsetup status dust1
+0 33552384 dust 252:17 fail_read_on_bad_block
+
+With the device in "fail read on bad block" mode, attempting to read a
+block will encounter an "Input/output error":
+
+$ sudo dd if=/dev/mapper/dust1 of=/dev/null bs=512 count=1 skip=67 iflag=direct
+dd: error reading '/dev/mapper/dust1': Input/output error
+0+0 records in
+0+0 records out
+0 bytes copied, 0.00040651 s, 0.0 kB/s
+
+...and writing to the bad blocks will remove the blocks from the list,
+therefore emulating the "remap" behavior of hard disk drives:
+
+$ sudo dd if=/dev/zero of=/dev/mapper/dust1 bs=512 count=128 oflag=direct
+128+0 records in
+128+0 records out
+
+kernel: device-mapper: dust: block 60 removed from badblocklist by write
+kernel: device-mapper: dust: block 67 removed from badblocklist by write
+kernel: device-mapper: dust: block 72 removed from badblocklist by write
+kernel: device-mapper: dust: block 87 removed from badblocklist by write
+
+Bad block add/remove error handling:
+------------------------------------
+
+Attempting to add a bad block that already exists in the list will
+result in an "Invalid argument" error, as well as a helpful message:
+
+$ sudo dmsetup message dust1 0 addbadblock 88
+device-mapper: message ioctl on dust1  failed: Invalid argument
+kernel: device-mapper: dust: block 88 already in badblocklist
+
+Attempting to remove a bad block that doesn't exist in the list will
+result in an "Invalid argument" error, as well as a helpful message:
+
+$ sudo dmsetup message dust1 0 removebadblock 87
+device-mapper: message ioctl on dust1  failed: Invalid argument
+kernel: device-mapper: dust: block 87 not found in badblocklist
+
+Counting the number of bad blocks in the bad block list:
+--------------------------------------------------------
+
+To count the number of bad blocks configured in the device, run the
+following message command:
+
+$ sudo dmsetup message dust1 0 countbadblocks
+
+A message will print with the number of bad blocks currently
+configured on the device:
+
+kernel: device-mapper: dust: countbadblocks: 895 badblock(s) found
+
+Querying for specific bad blocks:
+---------------------------------
+
+To find out if a specific block is in the bad block list, run the
+following message command:
+
+$ sudo dmsetup message dust1 0 queryblock 72
+
+The following message will print if the block is in the list:
+device-mapper: dust: queryblock: block 72 found in badblocklist
+
+The following message will print if the block is in the list:
+device-mapper: dust: queryblock: block 72 not found in badblocklist
+
+The "queryblock" message command will work in both the "enabled"
+and "disabled" modes, allowing the verification of whether a block
+will be treated as "bad" without having to issue I/O to the device,
+or having to "enable" the bad block emulation.
+
+Clearing the bad block list:
+----------------------------
+
+To clear the bad block list (without needing to individually run
+a "removebadblock" message command for every block), run the
+following message command:
+
+$ sudo dmsetup message dust1 0 clearbadblocks
+
+After clearing the bad block list, the following message will appear:
+
+kernel: device-mapper: dust: clearbadblocks: badblocks cleared
+
+If there were no bad blocks to clear, the following message will
+appear:
+
+kernel: device-mapper: dust: clearbadblocks: no badblocks found
+
+Message commands list:
+----------------------
+
+Below is a list of the messages that can be sent to a dust device:
+
+Operations on blocks (requires a <blknum> argument):
+
+addbadblock <blknum>
+queryblock <blknum>
+removebadblock <blknum>
+
+...where <blknum> is a block number within range of the device
+  (corresponding to the block size of the device.)
+
+Single argument message commands:
+
+countbadblocks
+clearbadblocks
+disable
+enable
+quiet
+
+Device removal:
+---------------
+
+When finished, remove the device via the "dmsetup remove" command:
+
+$ sudo dmsetup remove dust1
+
+Quiet mode:
+-----------
+
+On test runs with many bad blocks, it may be desirable to avoid
+excessive logging (from bad blocks added, removed, or "remapped").
+This can be done by enabling "quiet mode" via the following message:
+
+$ sudo dmsetup message dust1 0 quiet
+
+This will suppress log messages from add / remove / removed by write
+operations.  Log messages from "countbadblocks" or "queryblock"
+message commands will still print in quiet mode.
+
+The status of quiet mode can be seen by running "dmsetup status":
+
+$ sudo dmsetup status dust1
+0 33552384 dust 252:17 fail_read_on_bad_block quiet
+
+To disable quiet mode, send the "quiet" message again:
+
+$ sudo dmsetup message dust1 0 quiet
+
+$ sudo dmsetup status dust1
+0 33552384 dust 252:17 fail_read_on_bad_block verbose
+
+(The presence of "verbose" indicates normal logging.)
+
+"Why not...?"
+-------------
+
+scsi_debug has a "medium error" mode that can fail reads on one
+specified sector (sector 0x1234, hardcoded in the source code), but
+it uses RAM for the persistent storage, which drastically decreases
+the potential device size.
+
+dm-flakey fails all I/O from all block locations at a specified time
+frequency, and not a given point in time.
+
+When a bad sector occurs on a hard disk drive, reads to that sector
+are failed by the device, usually resulting in an error code of EIO
+("I/O error") or ENODATA ("No data available").  However, a write to
+the sector may succeed, and result in the sector becoming readable
+after the device controller no longer experiences errors reading the
+sector (or after a reallocation of the sector).  However, there may
+be bad sectors that occur on the device in the future, in a different,
+unpredictable location.
+
+This target seeks to provide a device that can exhibit the behavior
+of a bad sector at a known sector location, at a known time, based
+on a large storage device (at least tens of gigabytes, not occupying
+system memory).

+Allwinner Memory Bus (MBUS) controller
+
+The MBUS controller drives the MBUS that other devices in the SoC will
+use to perform DMA. It also has a register interface that allows to
+monitor and control the bandwidth and priorities for masters on that
+bus.
+
+Required properties:
+ - compatible: Must be one of:
+	- allwinner,sun5i-a13-mbus
+ - reg: Offset and length of the register set for the controller
+ - clocks: phandle to the clock driving the controller
+ - dma-ranges: See section 2.3.9 of the DeviceTree Specification
+ - #interconnect-cells: Must be one, with the argument being the MBUS
+   port ID
+
+Each device having to perform their DMA through the MBUS must have the
+interconnects and interconnect-names properties set to the MBUS
+controller and with "dma-mem" as the interconnect name.
+
+Example:
+
+mbus: dram-controller@1c01000 {
+	compatible = "allwinner,sun5i-a13-mbus";
+	reg = <0x01c01000 0x1000>;

+Cirrus Logic Lochnagar Audio Development Board
+
+Lochnagar is an evaluation and development board for Cirrus Logic
+Smart CODEC and Amp devices. It allows the connection of most Cirrus
+Logic devices on mini-cards, as well as allowing connection of
+various application processor systems to provide a full evaluation
+platform.  Audio system topology, clocking and power can all be
+controlled through the Lochnagar, allowing the device under test
+to be used in a variety of possible use cases.
+
+This binding document describes the binding for the clock portion of
+the driver.
+
+Also see these documents for generic binding information:
+  [1] Clock : ../clock/clock-bindings.txt
+
+And these for relevant defines:
+  [2] include/dt-bindings/clock/lochnagar.h
+
+This binding must be part of the Lochnagar MFD binding:
+  [3] ../mfd/cirrus,lochnagar.txt
+
+Required properties:
+
+  - compatible : One of the following strings:
+                 "cirrus,lochnagar1-clk"
+                 "cirrus,lochnagar2-clk"
+
+  - #clock-cells : Must be 1. The first cell indicates the clock
+    number, see [2] for available clocks and [1].
+
+Optional properties:
+
+  - clocks : Must contain an entry for each clock in clock-names.
+  - clock-names : May contain entries for each of the following
+    clocks:
+     - ln-cdc-clkout : Output clock from CODEC card.
+     - ln-dsp-clkout : Output clock from DSP card.
+     - ln-gf-mclk1,ln-gf-mclk2,ln-gf-mclk3,ln-gf-mclk4 : Optional
+       input audio clocks from host system.
+     - ln-psia1-mclk, ln-psia2-mclk : Optional input audio clocks from
+       external connector.
+     - ln-spdif-clkout : Optional input audio clock from SPDIF.
+     - ln-adat-mclk : Optional input audio clock from ADAT.
+     - ln-pmic-32k : On board fixed clock.
+     - ln-clk-12m : On board fixed clock.
+     - ln-clk-11m : On board fixed clock.
+     - ln-clk-24m : On board fixed clock.
+     - ln-clk-22m : On board fixed clock.
+     - ln-clk-8m : On board fixed clock.
+     - ln-usb-clk-24m : On board fixed clock.
+     - ln-usb-clk-12m : On board fixed clock.
+
+  - assigned-clocks : A list of Lochnagar clocks to be reparented, see

+SiFive FU540 PRCI bindings
+
+On the FU540 family of SoCs, most system-wide clock and reset integration
+is via the PRCI IP block.
+
+Required properties:
+- compatible: Should be "sifive,<chip>-prci".  Only one value is
+	supported: "sifive,fu540-c000-prci"
+- reg: Should describe the PRCI's register target physical address region
+- clocks: Should point to the hfclk device tree node and the rtcclk
+          device tree node.  The RTC clock here is not a time-of-day clock,
+	  but is instead a high-stability clock source for system timers
+	  and cycle counters.
+- #clock-cells: Should be <1>
+
+The clock consumer should specify the desired clock via the clock ID
+macros defined in include/dt-bindings/clock/sifive-fu540-prci.h.
+These macros begin with PRCI_CLK_.
+
+The hfclk and rtcclk nodes are required, and represent physical
+crystals or resonators located on the PCB.  These nodes should be present
+underneath /, rather than /soc.
+
+Examples:
+
+/* under /, in PCB-specific DT data */
+hfclk: hfclk {
+	#clock-cells = <0>;
+	compatible = "fixed-clock";
+	clock-frequency = <33333333>;

+Zynq MPSoC firmware interface
+--------------------------------------------------------------------------
+The clock controller is a h/w block of Zynq Ultrascale+ MPSoC clock
+tree. It reads required input clock frequencies from the devicetree and acts
+as clock provider for all clock consumers of PS clocks.
+
+See clock_bindings.txt for more information on the generic clock bindings.
+
+Required properties:
+ - #clock-cells:	Must be 1
+ - compatible:		Must contain:	"xlnx,zynqmp-clk"
+ - clocks:		List of clock specifiers which are external input
+			clocks to the given clock controller. Please refer
+			the next section to find the input clocks for a
+			given controller.
+ - clock-names:		List of clock names which are exteral input clocks
+			to the given clock controller. Please refer to the
+			clock bindings for more details.
+
+Input clocks for zynqmp Ultrascale+ clock controller:
+
+The Zynq UltraScale+ MPSoC has one primary and four alternative reference clock
+inputs. These required clock inputs are:
+ - pss_ref_clk (PS reference clock)
+ - video_clk (reference clock for video system )
+ - pss_alt_ref_clk (alternative PS reference clock)
+ - aux_ref_clk
+ - gt_crx_ref_clk (transceiver reference clock)
+
+The following strings are optional parameters to the 'clock-names' property in
+order to provide an optional (E)MIO clock source:
+ - swdt0_ext_clk
+ - swdt1_ext_clk
+ - gem0_emio_clk
+ - gem1_emio_clk
+ - gem2_emio_clk
+ - gem3_emio_clk
+ - mio_clk_XX		# with XX = 00..77
+ - mio_clk_50_or_51	#for the mux clock to gem tsu from 50 or 51
+
+
+Output clocks are registered based on clock information received
+from firmware. Output clocks indexes are mentioned in
+include/dt-bindings/clock/xlnx-zynqmp-clk.h.

-Simple Framebuffer
-
-A simple frame-buffer describes a frame-buffer setup by firmware or
-the bootloader, with the assumption that the display hardware has already
-been set up to scan out from the memory pointed to by the reg property.
-
-Since simplefb nodes represent runtime information they must be sub-nodes of
-the chosen node (*). Simplefb nodes must be named "framebuffer@<address>".
-
-If the devicetree contains nodes for the display hardware used by a simplefb,
-then the simplefb node must contain a property called "display", which
-contains a phandle pointing to the primary display hw node, so that the OS
-knows which simplefb to disable when handing over control to a driver for the
-real hardware. The bindings for the hw nodes must specify which node is
-considered the primary node.
-
-It is advised to add display# aliases to help the OS determine how to number
-things. If display# aliases are used, then if the simplefb node contains a
-"display" property then the /aliases/display# path must point to the display
-hw node the "display" property points to, otherwise it must point directly
-to the simplefb node.
-
-If a simplefb node represents the preferred console for user interaction,
-then the chosen node's stdout-path property should point to it, or to the
-primary display hw node, as with display# aliases. If display aliases are
-used then it should be set to the alias instead.
-
-It is advised that devicetree files contain pre-filled, disabled framebuffer
-nodes, so that the firmware only needs to update the mode information and
-enable them. This way if e.g. later on support for more display clocks get
-added, the simplefb nodes will already contain this info and the firmware
-does not need to be updated.
-
-If pre-filled framebuffer nodes are used, the firmware may need extra
-information to find the right node. In that case an extra platform specific
-compatible and platform specific properties should be used and documented,
-see e.g. simple-framebuffer-sunxi.txt .
-
-Required properties:
-- compatible: "simple-framebuffer"
-- reg: Should contain the location and size of the framebuffer memory.
-- width: The width of the framebuffer in pixels.
-- height: The height of the framebuffer in pixels.
-- stride: The number of bytes in each line of the framebuffer.
-- format: The format of the framebuffer surface. Valid values are:
-  - r5g6b5 (16-bit pixels, d[15:11]=r, d[10:5]=g, d[4:0]=b).
-  - a8b8g8r8 (32-bit pixels, d[31:24]=a, d[23:16]=b, d[15:8]=g, d[7:0]=r).
-
-Optional properties:
-- clocks : List of clocks used by the framebuffer.
-- *-supply : Any number of regulators used by the framebuffer. These should
-	     be named according to the names in the device's design.
-
-  The above resources are expected to already be configured correctly.
-  The OS must ensure they are not modified or disabled while the simple
-  framebuffer remains active.
-
-- display : phandle pointing to the primary display hardware node
-
-Example:
-
-aliases {
-	display0 = &lcdc0;
-}
-
-chosen {
-	framebuffer0: framebuffer@1d385000 {
-		compatible = "simple-framebuffer";
-		reg = <0x1d385000 (1600 * 1200 * 2)>;
-		width = <1600>;
-		height = <1200>;
-		stride = <(1600 * 2)>;
-		format = "r5g6b5";
-		clocks = <&ahb_gates 36>, <&ahb_gates 43>, <&ahb_gates 44>;
-		lcd-supply = <&reg_dc1sw>;

+ST-Ericsson Multi Channel Display Engine MCDE
+
+The ST-Ericsson MCDE is a display controller with support for compositing
+and displaying several channels memory resident graphics data on DSI or
+LCD displays or bridges. It is used in the ST-Ericsson U8500 platform.
+
+Required properties:
+
+- compatible: must be:
+  "ste,mcde"
+- reg: register base for the main MCDE control registers, should be
+  0x1000 in size
+- interrupts: the interrupt line for the MCDE
+- epod-supply: a phandle to the EPOD regulator
+- vana-supply: a phandle to the analog voltage regulator
+- clocks: an array of the MCDE clocks in this strict order:
+  MCDECLK (main MCDE clock), LCDCLK (LCD clock), PLLDSI
+  (HDMI clock), DSI0ESCLK (DSI0 energy save clock),
+  DSI1ESCLK (DSI1 energy save clock), DSI2ESCLK (DSI2 energy
+  save clock)
+- clock-names: must be the following array:
+  "mcde", "lcd", "hdmi"
+  to match the required clock inputs above.
+- #address-cells: should be <1> (for the DSI hosts that will be children)
+- #size-cells: should be <1> (for the DSI hosts that will be children)
+- ranges: this should always be stated
+
+Required subnodes:
+
+The devicetree must specify subnodes for the DSI host adapters.
+These must have the following characteristics:
+
+- compatible: must be:
+  "ste,mcde-dsi"
+- reg: must specify the register range for the DSI host
+- vana-supply: phandle to the VANA voltage regulator
+- clocks: phandles to the high speed and low power (energy save) clocks
+  the high speed clock is not present on the third (dsi2) block, so it
+  should only have the "lp" clock
+- clock-names: "hs" for the high speed clock and "lp" for the low power
+  (energy save) clock
+- #address-cells: should be <1>
+- #size-cells: should be <0>
+
+Display panels and bridges will appear as children on the DSI hosts, and
+the displays are connected to the DSI hosts using the common binding
+for video transmitter interfaces; see
+Documentation/devicetree/bindings/media/video-interfaces.txt
+
+If a DSI host is unused (not connected) it will have no children defined.

+* Arcx Anybus-S controller
+
+This chip communicates with the SoC over a parallel bus. It is
+expected that its Device Tree node is specified as the child of a node
+corresponding to the parallel bus used for communication.
+
+Required properties:
+--------------------
+
+  - compatible : The following chip-specific string:
+        "arcx,anybus-controller"
+
+  - reg : three areas:
+	index 0: bus memory area where the cpld registers are located.
+	index 1: bus memory area of the first  host's dual-port ram.
+	index 2: bus memory area of the second host's dual-port ram.
+
+  - reset-gpios : the GPIO pin connected to the reset line of the controller.
+
+  - interrupts : two interrupts:
+		index 0: interrupt connected to the first  host
+		index 1: interrupt connected to the second host
+	Generic interrupt client node bindings are described in
+	interrupt-controller/interrupts.txt
+
+Optional: use of subnodes
+-------------------------
+
+The card connected to a host may need additional properties. These can be
+specified in subnodes to the controller node.
+
+The subnodes are identified by the standard 'reg' property. Which information
+exactly can be specified depends on the bindings for the function driver
+for the subnode.
+
+Required controller node properties when using subnodes:
+- #address-cells: should be one.
+- #size-cells: should be zero.
+
+Required subnode properties:
+- reg: Must contain the host index of the card this subnode describes:
+		<0>	for the first  host on the controller
+		<1>	for the second host on the controller
+	Note that only a single card can be plugged into a host, so the host
+	index uniquely describes the card location.
+
+Example of usage:
+-----------------
+
+This example places the bridge on top of the i.MX WEIM parallel bus, see:
+Documentation/devicetree/bindings/bus/imx-weim.txt
+
+&weim {

+  On the IXP4xx SoCs, the Network Processing Engine (NPE) is a small
+  processor that can load a firmware to perform offloading of networking
+  and crypto tasks. It also manages the MDIO bus to the ethernet PHYs
+  on the IXP4xx platform. All IXP4xx platforms have three NPEs at
+  consecutive memory locations. They are all included in the same
+  device node since they are not independent of each other.

+Cirrus Logic Lochnagar Audio Development Board
+
+Lochnagar is an evaluation and development board for Cirrus Logic
+Smart CODEC and Amp devices. It allows the connection of most Cirrus
+Logic devices on mini-cards, as well as allowing connection of
+various application processor systems to provide a full evaluation
+platform.  Audio system topology, clocking and power can all be
+controlled through the Lochnagar, allowing the device under test
+to be used in a variety of possible use cases.
+
+This binding document describes the binding for the hardware monitor
+portion of the driver.

+	If this field is left empty, DIO1 is assigned as default data ready

+- reset-gpios: must be the device tree identifier of the RESET pin. As the line

+- clocks: phandle to the external clock. Should be set according to
+	"clock-names".
+	If this field is left empty together with the "clock-names" field, then
+	the internal clock is used.
+- clock-names: The name of the external clock to be used. Valid values are:
+	* sync: In sync mode, the internal clock is disabled and the frequency
+		of the external clock signal establishes therate of data
+		collection and processing. See Fig 14 and 15 in the datasheet.
+		The clock-frequency must be:
+		* 3000 to 4500 Hz for adis1649x devices.
+		* 700 to 2400 Hz for adis1648x devices.
+	* pps: In Pulse Per Second (PPS) Mode, the rate of data collection and
+	       production is equal to the product of the external clock
+	       frequency and the scale factor in the SYNC_SCALE register, see
+	       Table 154 in the datasheet.
+	       The clock-frequency must be:
+	       * 1 to 128 Hz for adis1649x devices.

+	Valid values are:
+	* DIO1
+	* DIO2
+	* DIO3
+	* DIO4
+	Each DIOx pin supports only one function at a time (data ready line
+	selection or external clock input). When a single pin has two
+	two assignments, the enable bit for the lower priority function
+	automatically resets to zero (disabling the lower priority function).
+	Data ready has highest priority.

+to be driven per N output. An Interrupt Router can either handle edge triggered
+or level triggered interrupts and that is fixed in hardware.

+There is one register per output (MUXCNTL_N) that controls the selection.
+Configuration of these MUXCNTL_N registers is done by a system controller
+(like the Device Memory and Security Controller on K3 AM654 SoC). System
+controller will keep track of the used and unused registers within the Router.
+Driver should request the system controller to get the range of GIC IRQs
+assigned to the requesting hosts. It is the drivers responsibility to keep
+track of Host IRQs.
+
+Communication between the host processor running an OS and the system
+controller happens through a protocol called TI System Control Interface
+(TISCI protocol). For more details refer:

+TISCI Interrupt Router Node:
+----------------------------
+Required Properties:
+- compatible:		Must be "ti,sci-intr".
+- ti,intr-trigger-type:	Should be one of the following:
+			1: If intr supports edge triggered interrupts.
+			4: If intr supports level triggered interrupts.
+- interrupt-controller:	Identifies the node as an interrupt controller
+- #interrupt-cells:	Specifies the number of cells needed to encode an
+			interrupt source. The value should be 2.
+			First cell should contain the TISCI device ID of source
+			Second cell should contain the interrupt source offset
+			within the device.
+- ti,sci:		Phandle to TI-SCI compatible System controller node.
+- ti,sci-dst-id:	TISCI device ID of the destination IRQ controller.
+- ti,sci-rm-range-girq:	Array of TISCI subtype ids representing the host irqs
+			assigned to this interrupt router. Each subtype id
+			corresponds to a range of host irqs.
+
+For more details on TISCI IRQ resource management refer:

+* Texas Instruments - lm3532 White LED driver with ambient light sensing
+capability.
+
+The LM3532 provides the 3 high-voltage, low-side current sinks. The device is
+programmable over an I2C-compatible interface and has independent
+current control for all three channels. The adaptive current regulation
+method allows for different LED currents in each current sink thus allowing
+for a wide variety of backlight and keypad applications.
+
+The main features of the LM3532 include dual ambient light sensor inputs
+each with 32 internal voltage setting resistors, 8-bit logarithmic and linear
+brightness control, dual external PWM brightness control inputs, and up to
+1000:1 dimming ratio with programmable fade in and fade out settings.

+======================================================================
+Device tree bindings for Aspeed AST2400/AST2500 PCI-to-AHB Bridge Control Driver
+======================================================================
+
+The bridge is available on platforms with the VGA enabled on the Aspeed device.
+In this case, the host has access to a 64KiB window into all of the BMC's
+memory.  The BMC can disable this bridge.  If the bridge is enabled, the host
+has read access to all the regions of memory, however the host only has read
+and write access depending on a register controlled by the BMC.
+
+Required properties:
+===================
+
+ - compatible: must be one of:
+	- "aspeed,ast2400-p2a-ctrl"
+	- "aspeed,ast2500-p2a-ctrl"
+
+Optional properties:
+===================
+
+- memory-region: A phandle to a reserved_memory region to be used for the PCI
+		to AHB mapping
+
+The p2a-control node should be the child of a syscon node with the required
+property:
+
+- compatible : Should be one of the following:
+		"aspeed,ast2400-scu", "syscon", "simple-mfd"
+		"aspeed,g4-scu", "syscon", "simple-mfd"
+		"aspeed,ast2500-scu", "syscon", "simple-mfd"

+description: |
+  The IXP4xx AHB Queue Manager maintains queues as circular buffers in
+  an 8KB embedded SRAM along with hardware pointers. It is used by both
+  the XScale processor and the NPEs (Network Processing Units) in the
+  IXP4xx for accelerating queues, especially for networking. Clients pick
+  queues from the queue manager with foo-queue = <&qmgr N> where the
+  &qmgr is a phandle to the queue manager and N is the queue resource
+  number. The queue resources available and their specific purpose
+  on a certain IXP4xx system will vary.

-Deprecated Binding
-------------------
-
-The deprecated binding makes use of a platform device to represent the
-switches. The switches themselves are not Linux devices, and make use
-of an MDIO bus for management.
-
-Required properties:
-- compatible		: Should be "marvell,dsa"
-- #address-cells	: Must be 2, first cell is the address on the MDIO bus
-			  and second cell is the address in the switch tree.
-			  Second cell is used only when cascading/chaining.
-- #size-cells		: Must be 0
-- dsa,ethernet		: Should be a phandle to a valid Ethernet device node
-- dsa,mii-bus		: Should be a phandle to a valid MDIO bus device node
-
-Optional properties:
-- interrupts		: property with a value describing the switch
-			  interrupt number (not supported by the driver)
-
-A DSA node can contain multiple switch chips which are therefore child nodes of
-the parent DSA node. The maximum number of allowed child nodes is 4
-(DSA_MAX_SWITCHES).
-Each of these switch child nodes should have the following required properties:
-
-- reg			: Contains two fields. The first one describes the
-			  address on the MII bus. The second is the switch
-			  number that must be unique in cascaded configurations
-- #address-cells	: Must be 1
-- #size-cells		: Must be 0
-
-A switch child node has the following optional property:
-
-- eeprom-length		: Set to the length of an EEPROM connected to the
-			  switch. Must be set if the switch can not detect
-			  the presence and/or size of a connected EEPROM,
-			  otherwise optional.
-
-A switch may have multiple "port" children nodes
-
-Each port children node must have the following mandatory properties:
-- reg			: Describes the port address in the switch
-- label			: Describes the label associated with this port, special
-			  labels are "cpu" to indicate a CPU port and "dsa" to
-			  indicate an uplink/downlink port.
-
-Note that a port labelled "dsa" will imply checking for the uplink phandle
-described below.
-
-Optional property:
-- link			: Should be a list of phandles to another switch's DSA port.
-			  This property is only used when switches are being
-			  chained/cascaded together. This port is used as outgoing port
-			  towards the phandle port, which can be more than one hop away.
-
-- phy-handle		: Phandle to a PHY on an external MDIO bus, not the
-			  switch internal one. See
-			  Documentation/devicetree/bindings/net/ethernet.txt
-			  for details.
-
-- phy-mode		: String representing the connection to the designated
-			  PHY node specified by the 'phy-handle' property. See
-			  Documentation/devicetree/bindings/net/ethernet.txt
-			  for details.
-
-- mii-bus		: Should be a phandle to a valid MDIO bus device node.
-			  This mii-bus will be used in preference to the
-			  global dsa,mii-bus defined above, for this switch.
-
-Optional subnodes:

+NXP SJA1105 switch driver
+=========================
+
+Required properties:
+
+- compatible:
+	Must be one of:
+	- "nxp,sja1105e"
+	- "nxp,sja1105t"
+	- "nxp,sja1105p"
+	- "nxp,sja1105q"
+	- "nxp,sja1105r"
+	- "nxp,sja1105s"
+
+	Although the device ID could be detected at runtime, explicit bindings
+	are required in order to be able to statically check their validity.
+	For example, SGMII can only be specified on port 4 of R and S devices,
+	and the non-SGMII devices, while pin-compatible, are not equal in terms
+	of support for RGMII internal delays (supported on P/Q/R/S, but not on
+	E/T).
+
+Optional properties:
+
+- sja1105,role-mac:
+- sja1105,role-phy:
+	Boolean properties that can be assigned under each port node. By
+	default (unless otherwise specified) a port is configured as MAC if it
+	is driving a PHY (phy-handle is present) or as PHY if it is PHY-less
+	(fixed-link specified, presumably because it is connected to a MAC).
+	The effect of this property (in either its implicit or explicit form)
+	is:
+	- In the case of MII or RMII it specifies whether the SJA1105 port is a
+	  clock source or sink for this interface (not applicable for RGMII
+	  where there is a Tx and an Rx clock).
+	- In the case of RGMII it affects the behavior regarding internal
+	  delays:
+	  1. If sja1105,role-mac is specified, and the phy-mode property is one
+	     of "rgmii-id", "rgmii-txid" or "rgmii-rxid", then the entity
+	     designated to apply the delay/clock skew necessary for RGMII
+	     is the PHY. The SJA1105 MAC does not apply any internal delays.
+	  2. If sja1105,role-phy is specified, and the phy-mode property is one
+	     of the above, the designated entity to apply the internal delays
+	     is the SJA1105 MAC (if hardware-supported). This is only supported
+	     by the second-generation (P/Q/R/S) hardware. On a first-generation
+	     E or T device, it is an error to specify an RGMII phy-mode other
+	     than "rgmii" for a port that is in fixed-link mode. In that case,
+	     the clock skew must either be added by the MAC at the other end of
+	     the fixed-link, or by PCB serpentine traces on the board.
+	These properties are required, for example, in the case where SJA1105
+	ports are at both ends of a MII/RMII PHY-less setup. One end would need
+	to have sja1105,role-mac, while the other sja1105,role-phy.
+
+See Documentation/devicetree/bindings/net/dsa/dsa.txt for the list of standard
+DSA required and optional properties.
+
+Other observations
+------------------
+
+The SJA1105 SPI interface requires a CS-to-CLK time (t2 in UM10944) of at least
+one half of t_CLK. At an SPI frequency of 1MHz, this means a minimum
+cs_sck_delay of 500ns. Ensuring that this SPI timing requirement is observed
+depends on the SPI bus master driver.

+PCI-PCI Bridge properties
+-------------------------
+
+PCIe root ports and switch ports may be described explicitly in the device
+tree, as children of the host bridge node. Even though those devices are
+discoverable by probing, it might be necessary to describe properties that
+aren't provided by standard PCIe capabilities.
+
+Required properties:
+
+- reg:
+   Identifies the PCI-PCI bridge. As defined in the IEEE Std 1275-1994
+   document, it is a five-cell address encoded as (phys.hi phys.mid
+   phys.lo size.hi size.lo). phys.hi should contain the device's BDF as
+   0b00000000 bbbbbbbb dddddfff 00000000. The other cells should be zero.
+
+   The bus number is defined by firmware, through the standard bridge
+   configuration mechanism. If this port is a switch port, then firmware
+   allocates the bus number and writes it into the Secondary Bus Number
+   register of the bridge directly above this port. Otherwise, the bus
+   number of a root port is the first number in the bus-range property,
+   defaulting to zero.
+
+   If firmware leaves the ARI Forwarding Enable bit set in the bridge
+   above this port, then phys.hi contains the 8-bit function number as
+   0b00000000 bbbbbbbb ffffffff 00000000. Note that the PCIe specification
+   recommends that firmware only leaves ARI enabled when it knows that the
+   OS is ARI-aware.
+
+Optional properties:
+
+- external-facing:
+   When present, the port is external-facing. All bridges and endpoints
+   downstream of this port are external to the machine. The OS can, for
+   example, use this information to identify devices that cannot be
+   trusted with relaxed DMA protection, as users could easily attach
+   malicious devices to this port.
+
+Example:
+
+pcie@10000000 {
+	compatible = "pci-host-ecam-generic";
+	...
+	pcie@0008 {
+		/* Root port 00:01.0 is external-facing */
+		reg = <0x00000800 0 0 0 0>;
+		external-facing;

+Bitmain BM1880 Pin Controller
+
+This binding describes the pin controller found in the BM1880 SoC.
+
+Required Properties:
+
+- compatible:   Should be "bitmain,bm1880-pinctrl"
+- reg:          Offset and length of pinctrl space in SCTRL.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration for BM1880 SoC
+includes only pinmux as there is no pinconf support available in SoC.
+
+Each configuration node can consist of multiple nodes describing the pinmux
+options. The name of each subnode is not important; all subnodes should be
+enumerated and processed purely based on their content.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinmux subnode:
+
+Required Properties:
+
+- pins:           An array of strings, each string containing the name of a pin.

+Cirrus Logic Lochnagar Audio Development Board
+
+Lochnagar is an evaluation and development board for Cirrus Logic
+Smart CODEC and Amp devices. It allows the connection of most Cirrus
+Logic devices on mini-cards, as well as allowing connection of
+various application processor systems to provide a full evaluation
+platform.  Audio system topology, clocking and power can all be
+controlled through the Lochnagar, allowing the device under test
+to be used in a variety of possible use cases.
+
+This binding document describes the binding for the pinctrl portion
+of the driver.
+
+Also see these documents for generic binding information:
+  [1] GPIO : ../gpio/gpio.txt
+  [2] Pinctrl: ../pinctrl/pinctrl-bindings.txt
+
+And these for relevant defines:
+  [3] include/dt-bindings/pinctrl/lochnagar.h
+
+This binding must be part of the Lochnagar MFD binding:
+  [4] ../mfd/cirrus,lochnagar.txt
+
+Required properties:
+
+  - compatible : One of the following strings:
+                 "cirrus,lochnagar-pinctrl"
+
+  - gpio-controller : Indicates this device is a GPIO controller.
+  - #gpio-cells : Must be 2. The first cell is the pin number, see
+    [3] for available pins and the second cell is used to specify
+    optional parameters, see [1].
+  - gpio-ranges : Range of pins managed by the GPIO controller, see
+    [1]. Both the GPIO and Pinctrl base should be set to zero and the
+    count to the appropriate of the LOCHNAGARx_PIN_NUM_GPIOS define,
+    see [3].
+
+  - pinctrl-names : A pinctrl state named "default" must be defined.
+  - pinctrl-0 : A phandle to the default pinctrl state.
+
+Required sub-nodes:
+
+The pin configurations are defined as a child of the pinctrl states
+node, see [2]. Each sub-node can have the following properties:

+* Mediatek MT8183 Pin Controller
+
+The Mediatek's Pin controller is used to control SoC pins.
+
+Required properties:
+- compatible: value should be one of the following.
+	"mediatek,mt8183-pinctrl", compatible with mt8183 pinctrl.
+- gpio-controller : Marks the device node as a gpio controller.
+- #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO
+  binding is used, the amount of cells must be specified as 2. See the below
+  mentioned gpio binding representation for description of particular cells.
+- gpio-ranges : gpio valid number range.
+- reg: physical address base for gpio base registers. There are 10 GPIO
+  physical address base in mt8183.
+
+Optional properties:
+- reg-names: gpio base register names. There are 10 gpio base register
+  names in mt8183. They are "iocfg0", "iocfg1", "iocfg2", "iocfg3", "iocfg4",
+  "iocfg5", "iocfg6", "iocfg7", "iocfg8", "eint".
+- interrupt-controller: Marks the device node as an interrupt controller
+- #interrupt-cells: Should be two.
+- interrupts : The interrupt outputs to sysirq.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+Subnode format
+A pinctrl node should contain at least one subnodes representing the
+pinctrl groups available on the machine. Each subnode will list the
+pins it needs, and how they should be configured, with regard to muxer
+configuration, pullups, drive strength, input enable/disable and input schmitt.
+
+    node {
+	pinmux = <PIN_NUMBER_PINMUX>;
+	GENERIC_PINCONFIG;
+    };
+
+Required properties:
+- pinmux: integer array, represents gpio pin number and mux setting.
+    Supported pin number and mux varies for different SoCs, and are defined
+    as macros in boot/dts/<soc>-pinfunc.h directly.
+
+Optional properties:
+- GENERIC_PINCONFIG: is the generic pinconfig options to use, bias-disable,
+    bias-pull-down, bias-pull-up, input-enable, input-disable, output-low,
+    output-high, input-schmitt-enable, input-schmitt-disable
+    and drive-strength are valid.
+
+    Some special pins have extra pull up strength, there are R0 and R1 pull-up
+    resistors available, but for user, it's only need to set R1R0 as 00, 01,
+    10 or 11. So It needs config "mediatek,pull-up-adv" or
+    "mediatek,pull-down-adv" to support arguments for those special pins.
+    Valid arguments are from 0 to 3.
+
+    mediatek,tdsel: An integer describing the steps for output level shifter
+      duty cycle when asserted (high pulse width adjustment). Valid arguments
+      are from 0 to 15.
+    mediatek,rdsel: An integer describing the steps for input level shifter
+      duty cycle when asserted (high pulse width adjustment). Valid arguments
+      are from 0 to 63.
+
+    When config drive-strength, it can support some arguments, such as
+    MTK_DRIVE_4mA, MTK_DRIVE_6mA, etc. See dt-bindings/pinctrl/mt65xx.h.
+    It can only support 2/4/6/8/10/12/14/16mA in mt8183.
+    For I2C pins, there are existing generic driving setup and the specific
+    driving setup. I2C pins can only support 2/4/6/8/10/12/14/16mA driving
+    adjustment in generic driving setup. But in specific driving setup,
+    they can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
+    driving setup for I2C pins, the existing generic driving setup will be
+    disabled. For some special features, we need the I2C pins specific
+    driving setup. The specific driving setup is controlled by E1E0EN.
+    So we need add extra vendor driving preperty instead of
+    the generic driving property.
+    We can add "mediatek,drive-strength-adv = <XXX>;" to describe the specific
+    driving setup property. "XXX" means the value of E1E0EN. EN is 0 or 1.
+    It is used to enable or disable the specific driving setup.
+    E1E0 is used to describe the detail strength specification of the I2C pin.
+    When E1=0/E0=0, the strength is 0.125mA.
+    When E1=0/E0=1, the strength is 0.25mA.
+    When E1=1/E0=0, the strength is 0.5mA.
+    When E1=1/E0=1, the strength is 1mA.
+    So the valid arguments of "mediatek,drive-strength-adv" are from 0 to 7.
+
+Examples:
+
+#include "mt8183-pinfunc.h"

+SiFive L2 Cache Controller
+--------------------------
+The SiFive Level 2 Cache Controller is used to provide access to fast copies
+of memory for masters in a Core Complex. The Level 2 Cache Controller also
+acts as directory-based coherency manager.
+All the properties in ePAPR/DeviceTree specification applies for this platform
+
+Required Properties:
+--------------------
+- compatible: Should be "sifive,fu540-c000-ccache" and "cache"
+
+- cache-block-size: Specifies the block size in bytes of the cache.
+  Should be 64
+
+- cache-level: Should be set to 2 for a level 2 cache
+
+- cache-sets: Specifies the number of associativity sets of the cache.
+  Should be 1024
+
+- cache-size: Specifies the size in bytes of the cache. Should be 2097152
+
+- cache-unified: Specifies the cache is a unified cache
+
+- interrupts: Must contain 3 entries (DirError, DataError and DataFail signals)
+
+- reg: Physical base address and size of L2 cache controller registers map
+
+Optional Properties:
+--------------------
+- next-level-cache: phandle to the next level cache if present.
+
+- memory-region: reference to the reserved-memory for the L2 Loosely Integrated
+  Memory region. The reserved memory node should be defined as per the bindings
+  in reserved-memory.txt

+DT compatible string versioning for SiFive open-source IP blocks
+
+This document describes the version specification for DT "compatible"
+strings for open-source SiFive IP blocks.  HDL for these IP blocks
+can be found in this public repository:
+
+https://github.com/sifive/sifive-blocks
+
+IP block-specific DT compatible strings are contained within the HDL,
+in the form "sifive,<ip-block-name><integer version number>".
+
+An example is "sifive,uart0" from:
+
+https://github.com/sifive/sifive-blocks/blob/v1.0/src/main/scala/devices/uart/UART.scala#L43
+
+Until these IP blocks (or IP integration) support version
+auto-discovery, the maintainers of these IP blocks intend to increment
+the suffixed number in the compatible string whenever the software
+interface to these IP blocks changes, or when the functionality of the
+underlying IP blocks changes in a way that software should be aware of.
+
+Driver developers can use compatible string "match" values such as
+"sifive,uart0" to indicate that their driver is compatible with the
+register interface and functionality associated with the relevant
+upstream sifive-blocks commits.  It is expected that most drivers will
+match on these IP block-specific compatible strings.
+
+DT data authors, when writing data for a particular SoC, should
+continue to specify an SoC-specific compatible string value, such as
+"sifive,fu540-c000-uart".  This way, if SoC-specific

+NXP Audio Mixer (AUDMIX).
+
+The Audio Mixer is a on-chip functional module that allows mixing of two
+audio streams into a single audio stream. Audio Mixer has two input serial
+audio interfaces. These are driven by two Synchronous Audio interface
+modules (SAI). Each input serial interface carries 8 audio channels in its
+frame in TDM manner. Mixer mixes audio samples of corresponding channels
+from two interfaces into a single sample. Before mixing, audio samples of
+two inputs can be attenuated based on configuration. The output of the
+Audio Mixer is also a serial audio interface. Like input interfaces it has
+the same TDM frame format. This output is used to drive the serial DAC TDM
+interface of audio codec and also sent to the external pins along with the
+receive path of normal audio SAI module for readback by the CPU.
+
+The output of Audio Mixer can be selected from any of the three streams
+ - serial audio input 1
+ - serial audio input 2
+ - mixed audio
+
+Mixing operation is independent of audio sample rate but the two audio
+input streams must have same audio sample rate with same number of channels
+in TDM frame to be eligible for mixing.
+
+Device driver required properties:
+=================================
+  - compatible		: Compatible list, contains "fsl,imx8qm-audmix"
+
+  - reg			: Offset and length of the register set for the device.
+
+  - clocks		: Must contain an entry for each entry in clock-names.

+  - power-domains	: Must contain the phandle to AUDMIX power domain node

+Amlogic Meson G12A DWC3 USB SoC Controller Glue
+
+The Amlogic G12A embeds a DWC3 USB IP Core configured for USB2 and USB3
+in host-only mode, and a DWC2 IP Core configured for USB2 peripheral mode
+only.
+
+A glue connects the DWC3 core to USB2 PHYs and optionnaly to an USB3 PHY.
+
+One of the USB2 PHY can be re-routed in peripheral mode to a DWC2 USB IP.
+
+The DWC3 Glue controls the PHY routing and power, an interrupt line is
+connected to the Glue to serve as OTG ID change detection.
+
+Required properties:
+- compatible:	Should be "amlogic,meson-g12a-usb-ctrl"
+- clocks:	a handle for the "USB" clock
+- resets:	a handle for the shared "USB" reset line
+- reg:		The base address and length of the registers
+- interrupts:	the interrupt specifier for the OTG detection
+- phys: 	handle to used PHYs on the system
+	- a <0> phandle can be used if a PHY is not used
+- phy-names:	names of the used PHYs on the system :
+	- "usb2-phy0" for USB2 PHY0 if USBHOST_A port is used
+	- "usb2-phy1" for USB2 PHY1 if USBOTG_B port is used
+	- "usb3-phy0" for USB3 PHY if USB3_0 is used
+- dr_mode:	should be "host", "peripheral", or "otg" depending on
+	the usage and configuration of the OTG Capable port.
+	- "host" and "peripheral" means a fixed Host or Device only connection
+	- "otg" means the port can be used as both Host or Device and
+	  be switched automatically using the OTG ID pin.
+
+Optional properties:
+- vbus-supply:	should be a phandle to the regulator controlling the VBUS
+		power supply when used in OTG switchable mode
+
+Required child nodes:
+
+A child node must exist to represent the core DWC3 IP block. The name of
+the node is not important. The content of the node is defined in dwc3.txt.

-USB OHCI controllers
-
-Required properties:
-- compatible : "generic-ohci"
-- reg : ohci controller register range (address and length)
-- interrupts : ohci controller interrupt
-
-Optional properties:
-- big-endian-regs : boolean, set this for hcds with big-endian registers
-- big-endian-desc : boolean, set this for hcds with big-endian descriptors
-- big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
-- no-big-frame-no : boolean, set if frame_no lives in bits [15:0] of HCCA
-- remote-wakeup-connected: remote wakeup is wired on the platform
-- num-ports : u32, to override the detected port count
-- clocks : a list of phandle + clock specifier pairs. In case of Renesas
-	   R-Car Gen3 SoCs:
-	   - if a host only channel: first clock should be host.
-	   - if a USB DRD channel: first clock should be host and second one
-				   should be peripheral.
-- phys : see usb-hcd.txt in the current directory
-- resets : a list of phandle + reset specifier pairs
-
-additionally the properties from usb-hcd.txt (in the current directory) are
-supported.
-
-Example:
-
-	ohci0: usb@1c14400 {
-		compatible = "allwinner,sun4i-a10-ohci", "generic-ohci";
-		reg = <0x01c14400 0x100>;
-		interrupts = <64>;
-		clocks = <&usb_clk 6>, <&ahb_gates 2>;
-		phys = <&usbphy 1>;
-		phy-names = "usb";

+DOs and DON'Ts for designing and writing Devicetree bindings
+
+This is a list of common review feedback items focused on binding design. With
+every rule, there are exceptions and bindings have many gray areas.
+
+For guidelines related to patches, see
+Documentation/devicetree/bindings/submitting-patches.txt
+
+
+Overall design
+
+- DO attempt to make bindings complete even if a driver doesn't support some
+  features. For example, if a device has an interrupt, then include the
+  'interrupts' property even if the driver is only polled mode.
+
+- DON'T refer to Linux or "device driver" in bindings. Bindings should be
+  based on what the hardware has, not what an OS and driver currently support.
+
+- DO use node names matching the class of the device. Many standard names are
+  defined in the DT Spec. If there isn't one, consider adding it.
+
+- DO check that the example matches the documentation especially after making
+  review changes.
+
+- DON'T create nodes just for the sake of instantiating drivers. Multi-function
+  devices only need child nodes when the child nodes have their own DT
+  resources. A single node can be multiple providers (e.g. clocks and resets).
+
+- DON'T use 'syscon' alone without a specific compatible string. A 'syscon'
+  hardware block should have a compatible string unique enough to infer the
+  register layout of the entire block (at a minimum).
+
+
+Properties
+
+- DO make 'compatible' properties specific. DON'T use wildcards in compatible
+  strings. DO use fallback compatibles when devices are the same as or a subset
+  of prior implementations. DO add new compatibles in case there are new
+  features or bugs.
+
+- DO use a vendor prefix on device specific property names. Consider if
+  properties could be common among devices of the same class. Check other
+  existing bindings for similar devices.
+
+- DON'T redefine common properties. Just reference the definition and define
+  constraints specific to the device.
+
+- DO use common property unit suffixes for properties with scientific units.
+  See property-units.txt.
+
+- DO define properties in terms of constraints. How many entries? What are
+  possible values? What is the order?
+
+
+Board/SoC .dts Files
+
+- DO put all MMIO devices under a bus node and not at the top-level.
+
+- DO use non-empty 'ranges' to limit the size of child buses/devices. 64-bit
+  platforms don't need all devices to have 64-bit address and size.

+Test Module
+===========
+
+Kselftest tests the kernel from userspace.  Sometimes things need
+testing from within the kernel, one method of doing this is to create a
+test module.  We can tie the module into the kselftest framework by
+using a shell script test runner.  ``kselftest_module.sh`` is designed
+to facilitate this process.  There is also a header file provided to
+assist writing kernel modules that are for use with kselftest:
+
+- ``tools/testing/kselftest/kselftest_module.h``
+- ``tools/testing/kselftest/kselftest_module.sh``
+
+How to use
+----------
+
+Here we show the typical steps to create a test module and tie it into
+kselftest.  We use kselftests for lib/ as an example.
+
+1. Create the test module
+
+2. Create the test script that will run (load/unload) the module
+   e.g. ``tools/testing/selftests/lib/printf.sh``
+
+3. Add line to config file e.g. ``tools/testing/selftests/lib/config``
+
+4. Add test script to makefile  e.g. ``tools/testing/selftests/lib/Makefile``
+
+5. Verify it works:
+
+.. code-block:: sh
+
+   # Assumes you have booted a fresh build of this kernel tree
+   cd /path/to/linux/tree
+   make kselftest-merge
+   make modules
+   sudo make modules_install
+   make TARGETS=lib kselftest
+
+Example Module
+--------------
+

+
+   #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

+Abstract
+========
+This document describes the ACPICA project and the relationship between
+ACPICA and Linux.  It also describes how ACPICA code in drivers/acpi/acpica,
+include/acpi and tools/power/acpi is automatically updated to follow the
+upstream.
+
+ACPICA Project
+==============
+
+The ACPI Component Architecture (ACPICA) project provides an operating
+system (OS)-independent reference implementation of the Advanced
+Configuration and Power Interface Specification (ACPI).  It has been
+adapted by various host OSes.  By directly integrating ACPICA, Linux can
+also benefit from the application experiences of ACPICA from other host
+OSes.
+
+The homepage of ACPICA project is: www.acpica.org, it is maintained and
+supported by Intel Corporation.
+
+The following figure depicts the Linux ACPI subsystem where the ACPICA
+adaptation is included::

+ACPICA Release
+==============
+
+The ACPICA project maintains its code base at the following repository URL:
+https://github.com/acpica/acpica.git. As a rule, a release is made every
+month.
+
+As the coding style adopted by the ACPICA project is not acceptable by
+Linux, there is a release process to convert the ACPICA git commits into
+Linux patches.  The patches generated by this process are referred to as
+"linuxized ACPICA patches".  The release process is carried out on a local
+copy the ACPICA git repository.  Each commit in the monthly release is
+converted into a linuxized ACPICA patch.  Together, they form the monthly
+ACPICA release patchset for the Linux ACPI community.  This process is
+illustrated in the following figure::

+
+   Before the linuxized ACPICA patches are sent to the Linux ACPI community
+   for review, there is a quality assurance build test process to reduce
+   porting issues.  Currently this build process only takes care of the
+   following kernel configuration options:
+   CONFIG_ACPI/CONFIG_ACPI_DEBUG/CONFIG_ACPI_DEBUGGER
+
+ACPICA Divergences
+==================
+
+Ideally, all of the ACPICA commits should be converted into Linux patches
+automatically without manual modifications, the "linux / master" tree should
+contain the ACPICA code that exactly corresponds to the ACPICA code
+contained in "new linuxized acpica" tree and it should be possible to run
+the release process fully automatically.
+
+As a matter of fact, however, there are source code differences between
+the ACPICA code in Linux and the upstream ACPICA code, referred to as
+"ACPICA Divergences".
+
+The various sources of ACPICA divergences include:
+   1. Legacy divergences - Before the current ACPICA release process was
+      established, there already had been divergences between Linux and
+      ACPICA. Over the past several years those divergences have been greatly
+      reduced, but there still are several ones and it takes time to figure
+      out the underlying reasons for their existence.
+   2. Manual modifications - Any manual modification (eg. coding style fixes)
+      made directly in the Linux sources obviously hurts the ACPICA release
+      automation.  Thus it is recommended to fix such issues in the ACPICA
+      upstream source code and generate the linuxized fix using the ACPICA
+      release utilities (please refer to Section 4 below for the details).
+   3. Linux specific features - Sometimes it's impossible to use the
+      current ACPICA APIs to implement features required by the Linux kernel,
+      so Linux developers occasionally have to change ACPICA code directly.
+      Those changes may not be acceptable by ACPICA upstream and in such cases
+      they are left as committed ACPICA divergences unless the ACPICA side can
+      implement new mechanisms as replacements for them.
+   4. ACPICA release fixups - ACPICA only tests commits using a set of the
+      user space simulation utilities, thus the linuxized ACPICA patches may
+      break the Linux kernel, leaving us build/boot failures.  In order to
+      avoid breaking Linux bisection, fixes are applied directly to the
+      linuxized ACPICA patches during the release process.  When the release
+      fixups are backported to the upstream ACPICA sources, they must follow
+      the upstream ACPICA rules and so further modifications may appear.
+      That may result in the appearance of new divergences.
+   5. Fast tracking of ACPICA commits - Some ACPICA commits are regression
+      fixes or stable-candidate material, so they are applied in advance with
+      respect to the ACPICA release process.  If such commits are reverted or
+      rebased on the ACPICA side in order to offer better solutions, new ACPICA
+      divergences are generated.
+
+ACPICA Development
+==================
+
+This paragraph guides Linux developers to use the ACPICA upstream release
+utilities to obtain Linux patches corresponding to upstream ACPICA commits
+before they become available from the ACPICA release process.
+
+   1. Cherry-pick an ACPICA commit
+
+   First you need to git clone the ACPICA repository and the ACPICA change
+   you want to cherry pick must be committed into the local repository.
+
+   Then the gen-patch.sh command can help to cherry-pick an ACPICA commit
+   from the ACPICA local repository::
+
+   $ git clone https://github.com/acpica/acpica
+   $ cd acpica
+   $ generate/linux/gen-patch.sh -u [commit ID]
+
+   Here the commit ID is the ACPICA local repository commit ID you want to
+   cherry pick.  It can be omitted if the commit is "HEAD".
+
+   2. Cherry-pick recent ACPICA commits
+
+   Sometimes you need to rebase your code on top of the most recent ACPICA
+   changes that haven't been applied to Linux yet.
+
+   You can generate the ACPICA release series yourself and rebase your code on
+   top of the generated ACPICA release patches::
+
+   $ git clone https://github.com/acpica/acpica
+   $ cd acpica
+   $ generate/linux/make-patches.sh -u [commit ID]
+
+   The commit ID should be the last ACPICA commit accepted by Linux.  Usually,
+   it is the commit modifying ACPI_CA_VERSION.  It can be found by executing
+   "git blame source/include/acpixf.h" and referencing the line that contains
+   "ACPI_CA_VERSION".
+
+   3. Inspect the current divergences
+
+   If you have local copies of both Linux and upstream ACPICA, you can generate
+   a diff file indicating the state of the current divergences::
+
+   # git clone https://github.com/acpica/acpica
+   # git clone http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+   # cd acpica
+   # generate/linux/divergences.sh -s ../linux

+ACPI Scan Handlers
+==================
+
+:Copyright: |copy| 2012, Intel Corporation
+
+:Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+During system initialization and ACPI-based device hot-add, the ACPI namespace
+is scanned in search of device objects that generally represent various pieces
+of hardware.  This causes a struct acpi_device object to be created and
+registered with the driver core for every device object in the ACPI namespace
+and the hierarchy of those struct acpi_device objects reflects the namespace
+layout (i.e. parent device objects in the namespace are represented by parent
+struct acpi_device objects and analogously for their children).  Those struct
+acpi_device objects are referred to as "device nodes" in what follows, but they
+should not be confused with struct device_node objects used by the Device Trees
+parsing code (although their role is analogous to the role of those objects).
+
+During ACPI-based device hot-remove device nodes representing pieces of hardware
+being removed are unregistered and deleted.
+
+The core ACPI namespace scanning code in drivers/acpi/scan.c carries out basic
+initialization of device nodes, such as retrieving common configuration
+information from the device objects represented by them and populating them with
+appropriate data, but some of them require additional handling after they have
+been registered.  For example, if the given device node represents a PCI host
+bridge, its registration should cause the PCI bus under that bridge to be
+enumerated and PCI devices on that bus to be registered with the driver core.
+Similarly, if the device node represents a PCI interrupt link, it is necessary
+to configure that link so that the kernel can use it.
+
+Those additional configuration tasks usually depend on the type of the hardware
+component represented by the given device node which can be determined on the
+basis of the device node's hardware ID (HID).  They are performed by objects
+called ACPI scan handlers represented by the following structure::
+
+	struct acpi_scan_handler {
+		const struct acpi_device_id *ids;
+		struct list_head list_node;
+		int (*attach)(struct acpi_device *dev, const struct acpi_device_id *id);
+		void (*detach)(struct acpi_device *dev);
+	};
+
+where ids is the list of IDs of device nodes the given handler is supposed to
+take care of, list_node is the hook to the global list of ACPI scan handlers
+maintained by the ACPI core and the .attach() and .detach() callbacks are
+executed, respectively, after registration of new device nodes and before
+unregistration of device nodes the handler attached to previously.
+
+The namespace scanning function, acpi_bus_scan(), first registers all of the
+device nodes in the given namespace scope with the driver core.  Then, it tries
+to match a scan handler against each of them using the ids arrays of the
+available scan handlers.  If a matching scan handler is found, its .attach()
+callback is executed for the given device node.  If that callback returns 1,
+that means that the handler has claimed the device node and is now responsible
+for carrying out any additional configuration tasks related to it.  It also will
+be responsible for preparing the device node for unregistration in that case.
+The device node's handler field is then populated with the address of the scan
+handler that has claimed it.
+
+If the .attach() callback returns 0, it means that the device node is not
+interesting to the given scan handler and may be matched against the next scan
+handler in the list.  If it returns a (negative) error code, that means that
+the namespace scan should be terminated due to a serious error.  The error code
+returned should then reflect the type of the error.
+
+The namespace trimming function, acpi_bus_trim(), first executes .detach()
+callbacks from the scan handlers of all device nodes in the given namespace
+scope (if they have scan handlers).  Next, it unregisters all of the device
+nodes in that scope.
+
+ACPI scan handlers can be added to the list maintained by the ACPI core with the
+help of the acpi_scan_add_handler() function taking a pointer to the new scan
+handler as an argument.  The order in which scan handlers are added to the list
+is the order in which they are matched against device nodes during namespace
+scans.
+
+All scan handles must be added to the list before acpi_bus_scan() is run for the
+first time and they cannot be removed from it.

+Generic Counter Interface
+=========================
+
+Introduction
+============
+
+Counter devices are prevalent within a diverse spectrum of industries.
+The ubiquitous presence of these devices necessitates a common interface
+and standard of interaction and exposure. This driver API attempts to
+resolve the issue of duplicate code found among existing counter device
+drivers by introducing a generic counter interface for consumption. The
+Generic Counter interface enables drivers to support and expose a common
+set of components and functionality present in counter devices.
+
+Theory
+======
+
+Counter devices can vary greatly in design, but regardless of whether
+some devices are quadrature encoder counters or tally counters, all
+counter devices consist of a core set of components. This core set of
+components, shared by all counter devices, is what forms the essence of
+the Generic Counter interface.
+
+There are three core components to a counter:
+
+* Count:
+  Count data for a set of Signals.
+
+* Signal:
+  Input data that is evaluated by the counter to determine the count
+  data.
+
+* Synapse:
+  The association of a Signal with a respective Count.
+
+COUNT
+-----
+A Count represents the count data for a set of Signals. The Generic
+Counter interface provides the following available count data types:
+
+* COUNT_POSITION:
+  Unsigned integer value representing position.
+
+A Count has a count function mode which represents the update behavior
+for the count data. The Generic Counter interface provides the following
+available count function modes:
+
+* Increase:
+  Accumulated count is incremented.
+
+* Decrease:
+  Accumulated count is decremented.
+
+* Pulse-Direction:
+  Rising edges on signal A updates the respective count. The input level
+  of signal B determines direction.
+
+* Quadrature:
+  A pair of quadrature encoding signals are evaluated to determine
+  position and direction. The following Quadrature modes are available:
+
+  - x1 A:
+    If direction is forward, rising edges on quadrature pair signal A
+    updates the respective count; if the direction is backward, falling
+    edges on quadrature pair signal A updates the respective count.
+    Quadrature encoding determines the direction.
+
+  - x1 B:
+    If direction is forward, rising edges on quadrature pair signal B
+    updates the respective count; if the direction is backward, falling
+    edges on quadrature pair signal B updates the respective count.
+    Quadrature encoding determines the direction.
+
+  - x2 A:
+    Any state transition on quadrature pair signal A updates the
+    respective count. Quadrature encoding determines the direction.
+
+  - x2 B:
+    Any state transition on quadrature pair signal B updates the
+    respective count. Quadrature encoding determines the direction.
+
+  - x4:
+    Any state transition on either quadrature pair signals updates the
+    respective count. Quadrature encoding determines the direction.
+
+A Count has a set of one or more associated Signals.
+
+SIGNAL
+------
+A Signal represents a counter input data; this is the input data that is
+evaluated by the counter to determine the count data; e.g. a quadrature
+signal output line of a rotary encoder. Not all counter devices provide
+user access to the Signal data.
+
+The Generic Counter interface provides the following available signal
+data types for when the Signal data is available for user access:
+
+* SIGNAL_LEVEL:
+  Signal line state level. The following states are possible:
+
+  - SIGNAL_LEVEL_LOW:
+    Signal line is in a low state.
+
+  - SIGNAL_LEVEL_HIGH:
+    Signal line is in a high state.
+
+A Signal may be associated with one or more Counts.
+
+SYNAPSE
+-------
+A Synapse represents the association of a Signal with a respective
+Count. Signal data affects respective Count data, and the Synapse
+represents this relationship.
+
+The Synapse action mode specifies the Signal data condition which
+triggers the respective Count's count function evaluation to update the
+count data. The Generic Counter interface provides the following
+available action modes:
+
+* None:
+  Signal does not trigger the count function. In Pulse-Direction count
+  function mode, this Signal is evaluated as Direction.
+
+* Rising Edge:
+  Low state transitions to high state.
+
+* Falling Edge:
+  High state transitions to low state.
+
+* Both Edges:
+  Any state transition.
+
+A counter is defined as a set of input signals associated with count
+data that are generated by the evaluation of the state of the associated
+input signals as defined by the respective count functions. Within the
+context of the Generic Counter interface, a counter consists of Counts
+each associated with a set of Signals, whose respective Synapse
+instances represent the count function update conditions for the
+associated Counts.
+
+Paradigm
+========
+
+The most basic counter device may be expressed as a single Count
+associated with a single Signal via a single Synapse. Take for example
+a counter device which simply accumulates a count of rising edges on a
+source input line::
+
+                Count                Synapse        Signal
+                -----                -------        ------
+        +---------------------+
+        | Data: Count         |    Rising Edge     ________
+        | Function: Increase  |  <-------------   / Source \
+        |                     |                  ____________
+        +---------------------+
+
+In this example, the Signal is a source input line with a pulsing
+voltage, while the Count is a persistent count value which is repeatedly
+incremented. The Signal is associated with the respective Count via a
+Synapse. The increase function is triggered by the Signal data condition
+specified by the Synapse -- in this case a rising edge condition on the
+voltage input line. In summary, the counter device existence and
+behavior is aptly represented by respective Count, Signal, and Synapse
+components: a rising edge condition triggers an increase function on an
+accumulating count datum.
+
+A counter device is not limited to a single Signal; in fact, in theory
+many Signals may be associated with even a single Count. For example, a
+quadrature encoder counter device can keep track of position based on
+the states of two input lines::
+
+                   Count                 Synapse     Signal
+                   -----                 -------     ------
+        +-------------------------+
+        | Data: Position          |    Both Edges     ___
+        | Function: Quadrature x4 |  <------------   / A \
+        |                         |                 _______
+        |                         |
+        |                         |    Both Edges     ___
+        |                         |  <------------   / B \
+        |                         |                 _______
+        +-------------------------+
+
+In this example, two Signals (quadrature encoder lines A and B) are
+associated with a single Count: a rising or falling edge on either A or
+B triggers the "Quadrature x4" function which determines the direction
+of movement and updates the respective position data. The "Quadrature
+x4" function is likely implemented in the hardware of the quadrature
+encoder counter device; the Count, Signals, and Synapses simply
+represent this hardware behavior and functionality.
+
+Signals associated with the same Count can have differing Synapse action
+mode conditions. For example, a quadrature encoder counter device
+operating in a non-quadrature Pulse-Direction mode could have one input
+line dedicated for movement and a second input line dedicated for
+direction::
+
+                   Count                   Synapse      Signal
+                   -----                   -------      ------
+        +---------------------------+
+        | Data: Position            |    Rising Edge     ___
+        | Function: Pulse-Direction |  <-------------   / A \ (Movement)
+        |                           |                  _______
+        |                           |
+        |                           |       None         ___
+        |                           |  <-------------   / B \ (Direction)
+        |                           |                  _______
+        +---------------------------+
+
+Only Signal A triggers the "Pulse-Direction" update function, but the
+instantaneous state of Signal B is still required in order to know the
+direction so that the position data may be properly updated. Ultimately,
+both Signals are associated with the same Count via two respective
+Synapses, but only one Synapse has an active action mode condition which
+triggers the respective count function while the other is left with a
+"None" condition action mode to indicate its respective Signal's
+availability for state evaluation despite its non-triggering mode.
+
+Keep in mind that the Signal, Synapse, and Count are abstract
+representations which do not need to be closely married to their
+respective physical sources. This allows the user of a counter to
+divorce themselves from the nuances of physical components (such as
+whether an input line is differential or single-ended) and instead focus
+on the core idea of what the data and process represent (e.g. position
+as interpreted from quadrature encoding data).
+
+Userspace Interface
+===================
+
+Several sysfs attributes are generated by the Generic Counter interface,
+and reside under the /sys/bus/counter/devices/counterX directory, where
+counterX refers to the respective counter device. Please see
+Documentation/ABI/testing/sys-bus-counter-generic-sysfs for detailed
+information on each Generic Counter interface sysfs attribute.
+
+Through these sysfs attributes, programs and scripts may interact with
+the Generic Counter paradigm Counts, Signals, and Synapses of respective
+counter devices.
+
+Driver API
+==========
+
+Driver authors may utilize the Generic Counter interface in their code
+by including the include/linux/counter.h header file. This header file
+provides several core data structures, function prototypes, and macros
+for defining a counter device.
+
+.. kernel-doc:: include/linux/counter.h
+   :internal:
+
+.. kernel-doc:: drivers/counter/counter.c
+   :export:
+
+Implementation
+==============
+
+To support a counter device, a driver must first allocate the available
+Counter Signals via counter_signal structures. These Signals should
+be stored as an array and set to the signals array member of an
+allocated counter_device structure before the Counter is registered to
+the system.
+
+Counter Counts may be allocated via counter_count structures, and
+respective Counter Signal associations (Synapses) made via
+counter_synapse structures. Associated counter_synapse structures are
+stored as an array and set to the the synapses array member of the
+respective counter_count structure. These counter_count structures are
+set to the counts array member of an allocated counter_device structure
+before the Counter is registered to the system.
+
+Driver callbacks should be provided to the counter_device structure via
+a constant counter_ops structure in order to communicate with the
+device: to read and write various Signals and Counts, and to set and get
+the "action mode" and "function mode" for various Synapses and Counts
+respectively.
+
+A defined counter_device structure may be registered to the system by
+passing it to the counter_register function, and unregistered by passing
+it to the counter_unregister function. Similarly, the
+devm_counter_register and devm_counter_unregister functions may be used
+if device memory-managed registration is desired.
+
+Extension sysfs attributes can be created for auxiliary functionality
+and data by passing in defined counter_device_ext, counter_count_ext,
+and counter_signal_ext structures. In these cases, the
+counter_device_ext structure is used for global configuration of the
+respective Counter device, while the counter_count_ext and
+counter_signal_ext structures allow for auxiliary exposure and
+configuration of a specific Count or Signal respectively.
+
+Architecture
+============
+
+When the Generic Counter interface counter module is loaded, the
+counter_init function is called which registers a bus_type named
+"counter" to the system. Subsequently, when the module is unloaded, the
+counter_exit function is called which unregisters the bus_type named
+"counter" from the system.
+
+Counter devices are registered to the system via the counter_register
+function, and later removed via the counter_unregister function. The
+counter_register function establishes a unique ID for the Counter
+device and creates a respective sysfs directory, where X is the
+mentioned unique ID:
+
+    /sys/bus/counter/devices/counterX
+
+Sysfs attributes are created within the counterX directory to expose
+functionality, configurations, and data relating to the Counts, Signals,
+and Synapses of the Counter device, as well as options and information
+for the Counter device itself.
+
+Each Signal has a directory created to house its relevant sysfs
+attributes, where Y is the unique ID of the respective Signal:
+
+    /sys/bus/counter/devices/counterX/signalY
+
+Similarly, each Count has a directory created to house its relevant
+sysfs attributes, where Y is the unique ID of the respective Count:
+
+    /sys/bus/counter/devices/counterX/countY
+
+For a more detailed breakdown of the available Generic Counter interface
+sysfs attributes, please refer to the
+Documentation/ABI/testing/sys-bus-counter file.
+
+The Signals and Counts associated with the Counter device are registered
+to the system as well by the counter_register function. The
+signal_read/signal_write driver callbacks are associated with their
+respective Signal attributes, while the count_read/count_write and
+function_get/function_set driver callbacks are associated with their
+respective Count attributes; similarly, the same is true for the
+action_get/action_set driver callbacks and their respective Synapse
+attributes. If a driver callback is left undefined, then the respective
+read/write permission is left disabled for the relevant attributes.
+
+Similarly, extension sysfs attributes are created for the defined
+counter_device_ext, counter_count_ext, and counter_signal_ext
+structures that are passed in.

 GPIO drivers providing IRQs
----------------------------
+===========================
+
 It is custom that GPIO drivers (GPIO chips) are also providing interrupts,
 most often cascaded off a parent interrupt controller, and in some special
 cases the GPIO logic is melded with a SoC's primary interrupt controller.
 
-The IRQ portions of the GPIO block are implemented using an irqchip, using
+The IRQ portions of the GPIO block are implemented using an irq_chip, using
 the header <linux/irq.h>. So basically such a driver is utilizing two sub-
 systems simultaneously: gpio and irq.
 
-RT_FULL: a realtime compliant GPIO driver should not use spinlock_t or any
-sleepable APIs (like PM runtime) as part of its irq_chip implementation.
+It is legal for any IRQ consumer to request an IRQ from any irqchip even if it
+is a combined GPIO+IRQ driver. The basic premise is that gpio_chip and
+irq_chip are orthogonal, and offering their services independent of each
+other.
 
-* spinlock_t should be replaced with raw_spinlock_t [1].
-* If sleepable APIs have to be used, these can be done from the .irq_bus_lock()
+gpiod_to_irq() is just a convenience function to figure out the IRQ for a
+certain GPIO line and should not be relied upon to have been called before
+the IRQ is used.
+
+Always prepare the hardware and make it ready for action in respective
+callbacks from the GPIO and irq_chip APIs. Do not rely on gpiod_to_irq() having
+been called first.
+
+We can divide GPIO irqchips in two broad categories:
+
+- CASCADED INTERRUPT CHIPS: this means that the GPIO chip has one common
+  interrupt output line, which is triggered by any enabled GPIO line on that
+  chip. The interrupt output line will then be routed to an parent interrupt
+  controller one level up, in the most simple case the systems primary
+  interrupt controller. This is modeled by an irqchip that will inspect bits
+  inside the GPIO controller to figure out which line fired it. The irqchip
+  part of the driver needs to inspect registers to figure this out and it
+  will likely also need to acknowledge that it is handling the interrupt
+  by clearing some bit (sometime implicitly, by just reading a status
+  register) and it will often need to set up the configuration such as
+  edge sensitivity (rising or falling edge, or high/low level interrupt for
+  example).
+
+- HIERARCHICAL INTERRUPT CHIPS: this means that each GPIO line has a dedicated
+  irq line to a parent interrupt controller one level up. There is no need
+  to inquire the GPIO hardware to figure out which line has figured, but it
+  may still be necessary to acknowledge the interrupt and set up the
+  configuration such as edge sensitivity.
+
+Realtime considerations: a realtime compliant GPIO driver should not use
+spinlock_t or any sleepable APIs (like PM runtime) as part of its irqchip

+=========================================================
+Special Usage Model of the ACPI Control Method Lid Device
+=========================================================
+
+:Copyright: |copy| 2016, Intel Corporation
+
+:Author: Lv Zheng <lv.zheng@intel.com>
+
+Abstract
+========
+Platforms containing lids convey lid state (open/close) to OSPMs
+using a control method lid device. To implement this, the AML tables issue
+Notify(lid_device, 0x80) to notify the OSPMs whenever the lid state has
+changed. The _LID control method for the lid device must be implemented to
+report the "current" state of the lid as either "opened" or "closed".
+
+For most platforms, both the _LID method and the lid notifications are
+reliable. However, there are exceptions. In order to work with these
+exceptional buggy platforms, special restrictions and expections should be
+taken into account. This document describes the restrictions and the
+expections of the Linux ACPI lid device driver.
+
+
+Restrictions of the returning value of the _LID control method
+==============================================================
+
+The _LID control method is described to return the "current" lid state.
+However the word of "current" has ambiguity, some buggy AML tables return
+the lid state upon the last lid notification instead of returning the lid
+state upon the last _LID evaluation. There won't be difference when the
+_LID control method is evaluated during the runtime, the problem is its
+initial returning value. When the AML tables implement this control method
+with cached value, the initial returning value is likely not reliable.
+There are platforms always retun "closed" as initial lid state.
+
+Restrictions of the lid state change notifications
+==================================================
+
+There are buggy AML tables never notifying when the lid device state is
+changed to "opened". Thus the "opened" notification is not guaranteed. But
+it is guaranteed that the AML tables always notify "closed" when the lid
+state is changed to "closed". The "closed" notification is normally used to
+trigger some system power saving operations on Windows. Since it is fully
+tested, it is reliable from all AML tables.
+
+Expections for the userspace users of the ACPI lid device driver
+================================================================
+
+The ACPI button driver exports the lid state to the userspace via the
+following file::
+
+  /proc/acpi/button/lid/LID0/state
+
+This file actually calls the _LID control method described above. And given
+the previous explanation, it is not reliable enough on some platforms. So
+it is advised for the userspace program to not to solely rely on this file
+to determine the actual lid state.
+
+The ACPI button driver emits the following input event to the userspace:
+  * SW_LID
+
+The ACPI lid device driver is implemented to try to deliver the platform
+triggered events to the userspace. However, given the fact that the buggy
+firmware cannot make sure "opened"/"closed" events are paired, the ACPI
+button driver uses the following 3 modes in order not to trigger issues.
+
+If the userspace hasn't been prepared to ignore the unreliable "opened"
+events and the unreliable initial state notification, Linux users can use
+the following kernel parameters to handle the possible issues:
+
+A. button.lid_init_state=method:
+   When this option is specified, the ACPI button driver reports the
+   initial lid state using the returning value of the _LID control method
+   and whether the "opened"/"closed" events are paired fully relies on the
+   firmware implementation.
+
+   This option can be used to fix some platforms where the returning value
+   of the _LID control method is reliable but the initial lid state
+   notification is missing.
+
+   This option is the default behavior during the period the userspace
+   isn't ready to handle the buggy AML tables.
+
+B. button.lid_init_state=open:
+   When this option is specified, the ACPI button driver always reports the
+   initial lid state as "opened" and whether the "opened"/"closed" events
+   are paired fully relies on the firmware implementation.
+
+   This may fix some platforms where the returning value of the _LID
+   control method is not reliable and the initial lid state notification is
+   missing.
+
+If the userspace has been prepared to ignore the unreliable "opened" events
+and the unreliable initial state notification, Linux users should always
+use the following kernel parameter:
+
+C. button.lid_init_state=ignore:
+   When this option is specified, the ACPI button driver never reports the
+   initial lid state and there is a compensation mechanism implemented to
+   ensure that the reliable "closed" notifications can always be delievered
+   to the userspace by always pairing "closed" input events with complement
+   "opened" input events. But there is still no guarantee that the "opened"
+   notifications can be delivered to the userspace when the lid is actually
+   opens given that some AML tables do not send "opened" notifications
+   reliably.
+
+   In this mode, if everything is correctly implemented by the platform
+   firmware, the old userspace programs should still work. Otherwise, the
+   new userspace programs are required to work with the ACPI button driver.
+   This option will be the default behavior after the userspace is ready to
+   handle the buggy AML tables.

+The AML Debugger
+================
+
+:Copyright: |copy| 2016, Intel Corporation
+:Author: Lv Zheng <lv.zheng@intel.com>
+
+
+This document describes the usage of the AML debugger embedded in the Linux
+kernel.
+
+1. Build the debugger
+=====================
+
+The following kernel configuration items are required to enable the AML
+debugger interface from the Linux kernel::
+
+   CONFIG_ACPI_DEBUGGER=y
+   CONFIG_ACPI_DEBUGGER_USER=m
+
+The userspace utilities can be built from the kernel source tree using
+the following commands::
+
+   $ cd tools
+   $ make acpi
+
+The resultant userspace tool binary is then located at::
+
+   tools/power/acpi/acpidbg
+
+It can be installed to system directories by running "make install" (as a
+sufficiently privileged user).
+
+2. Start the userspace debugger interface
+=========================================
+
+After booting the kernel with the debugger built-in, the debugger can be
+started by using the following commands::
+
+   # mount -t debugfs none /sys/kernel/debug
+   # modprobe acpi_dbg
+   # tools/power/acpi/acpidbg
+
+That spawns the interactive AML debugger environment where you can execute
+debugger commands.
+
+The commands are documented in the "ACPICA Overview and Programmer Reference"
+that can be downloaded from
+
+https://acpica.org/documentation
+
+The detailed debugger commands reference is located in Chapter 12 "ACPICA
+Debugger Reference".  The "help" command can be used for a quick reference.
+
+3. Stop the userspace debugger interface
+========================================
+
+The interactive debugger interface can be closed by pressing Ctrl+C or using
+the "quit" or "exit" commands.  When finished, unload the module with::
+
+   # rmmod acpi_dbg
+
+The module unloading may fail if there is an acpidbg instance running.
+
+4. Run the debugger in a script
+===============================
+
+It may be useful to run the AML debugger in a test script. "acpidbg" supports
+this in a special "batch" mode.  For example, the following command outputs
+the entire ACPI namespace::
+
+   # acpidbg -b "namespace"

+====================
+APEI Error INJection
+====================
+
+EINJ provides a hardware error injection mechanism. It is very useful
+for debugging and testing APEI and RAS features in general.
+
+You need to check whether your BIOS supports EINJ first. For that, look
+for early boot messages similar to this one::
+
+  ACPI: EINJ 0x000000007370A000 000150 (v01 INTEL           00000001 INTL 00000001)
+
+which shows that the BIOS is exposing an EINJ table - it is the
+mechanism through which the injection is done.
+
+Alternatively, look in /sys/firmware/acpi/tables for an "EINJ" file,
+which is a different representation of the same thing.
+
+It doesn't necessarily mean that EINJ is not supported if those above
+don't exist: before you give up, go into BIOS setup to see if the BIOS
+has an option to enable error injection. Look for something called WHEA
+or similar. Often, you need to enable an ACPI5 support option prior, in
+order to see the APEI,EINJ,... functionality supported and exposed by
+the BIOS menu.
+
+To use EINJ, make sure the following are options enabled in your kernel
+configuration::
+
+  CONFIG_DEBUG_FS
+  CONFIG_ACPI_APEI
+  CONFIG_ACPI_APEI_EINJ
+
+The EINJ user interface is in <debugfs mount point>/apei/einj.
+
+The following files belong to it:
+
+- available_error_type
+
+  This file shows which error types are supported:
+
+  ================  ===================================
+  Error Type Value	Error Description
+  ================  ===================================
+  0x00000001        Processor Correctable
+  0x00000002        Processor Uncorrectable non-fatal
+  0x00000004        Processor Uncorrectable fatal
+  0x00000008        Memory Correctable
+  0x00000010        Memory Uncorrectable non-fatal

+  0x00000400        Platform Uncorrectable non-fatal
+  0x00000800        Platform Uncorrectable fatal
+  ================  ===================================
+
+  The format of the file contents are as above, except present are only
+  the available error types.
+
+- error_type
+
+  Set the value of the error type being injected. Possible error types
+  are defined in the file available_error_type above.
+
+- error_inject
+
+  Write any integer to this file to trigger the error injection. Make
+  sure you have specified all necessary error parameters, i.e. this
+  write should be the last step when injecting errors.
+
+- flags
+
+  Present for kernel versions 3.13 and above. Used to specify which
+  of param{1..4} are valid and should be used by the firmware during
+  injection. Value is a bitmask as specified in ACPI5.0 spec for the
+  SET_ERROR_TYPE_WITH_ADDRESS data structure:
+
+    Bit 0
+      Processor APIC field valid (see param3 below).
+    Bit 1
+      Memory address and mask valid (param1 and param2).
+    Bit 2
+      PCIe (seg,bus,dev,fn) valid (see param4 below).
+
+  If set to zero, legacy behavior is mimicked where the type of
+  injection specifies just one bit set, and param1 is multiplexed.
+
+- param1
+
+  This file is used to set the first error parameter value. Its effect
+  depends on the error type specified in error_type. For example, if
+  error type is memory related type, the param1 should be a valid
+  physical memory address. [Unless "flag" is set - see above]
+
+- param2
+
+  Same use as param1 above. For example, if error type is of memory
+  related type, then param2 should be a physical memory address mask.
+  Linux requires page or narrower granularity, say, 0xfffffffffffff000.
+
+- param3
+
+  Used when the 0x1 bit is set in "flags" to specify the APIC id
+
+- param4
+  Used when the 0x4 bit is set in "flags" to specify target PCIe device
+
+- notrigger
+
+  The error injection mechanism is a two-step process. First inject the
+  error, then perform some actions to trigger it. Setting "notrigger"
+  to 1 skips the trigger phase, which *may* allow the user to cause the
+  error in some other context by a simple access to the CPU, memory
+  location, or device that is the target of the error injection. Whether
+  this actually works depends on what operations the BIOS actually
+  includes in the trigger phase.
+
+BIOS versions based on the ACPI 4.0 specification have limited options
+in controlling where the errors are injected. Your BIOS may support an
+extension (enabled with the param_extension=1 module parameter, or boot
+command line einj.param_extension=1). This allows the address and mask
+for memory injections to be specified by the param1 and param2 files in
+apei/einj.
+
+BIOS versions based on the ACPI 5.0 specification have more control over
+the target of the injection. For processor-related errors (type 0x1, 0x2
+and 0x4), you can set flags to 0x3 (param3 for bit 0, and param1 and
+param2 for bit 1) so that you have more information added to the error
+signature being injected. The actual data passed is this::
+
+	memory_address = param1;
+	memory_address_range = param2;
+	apicid = param3;
+	pcie_sbdf = param4;
+
+For memory errors (type 0x8, 0x10 and 0x20) the address is set using
+param1 with a mask in param2 (0x0 is equivalent to all ones). For PCI
+express errors (type 0x40, 0x80 and 0x100) the segment, bus, device and
+function are specified using param1::
+
+         31     24 23    16 15    11 10      8  7        0
+	+-------------------------------------------------+
+	| segment |   bus  | device | function | reserved |
+	+-------------------------------------------------+
+
+Anyway, you get the idea, if there's doubt just take a look at the code
+in drivers/acpi/apei/einj.c.
+
+An ACPI 5.0 BIOS may also allow vendor-specific errors to be injected.
+In this case a file named vendor will contain identifying information
+from the BIOS that hopefully will allow an application wishing to use
+the vendor-specific extension to tell that they are running on a BIOS
+that supports it. All vendor extensions have the 0x80000000 bit set in
+error_type. A file vendor_flags controls the interpretation of param1
+and param2 (1 = PROCESSOR, 2 = MEMORY, 4 = PCI). See your BIOS vendor
+documentation for details (and expect changes to this API if vendors
+creativity in using this feature expands beyond our expectations).
+
+
+An error injection example::
+
+  # cd /sys/kernel/debug/apei/einj
+  # cat available_error_type		# See which errors can be injected
+  0x00000002	Processor Uncorrectable non-fatal
+  0x00000008	Memory Correctable
+  0x00000010	Memory Uncorrectable non-fatal
+  # echo 0x12345000 > param1		# Set memory address for injection
+  # echo $((-1 << 12)) > param2		# Mask 0xfffffffffffff000 - anywhere in this page
+  # echo 0x8 > error_type			# Choose correctable memory error
+  # echo 1 > error_inject			# Inject now
+
+You should see something like this in dmesg::

+=================
+ACPI Debug Output
+=================
+
+The ACPI CA, the Linux ACPI core, and some ACPI drivers can generate debug
+output.  This document describes how to use this facility.
+
+Compile-time configuration
+==========================
+
+ACPI debug output is globally enabled by CONFIG_ACPI_DEBUG.  If this config
+option is turned off, the debug messages are not even built into the
+kernel.
+
+Boot- and run-time configuration
+================================
+
+When CONFIG_ACPI_DEBUG=y, you can select the component and level of messages
+you're interested in.  At boot-time, use the acpi.debug_layer and
+acpi.debug_level kernel command line options.  After boot, you can use the
+debug_layer and debug_level files in /sys/module/acpi/parameters/ to control
+the debug messages.
+
+debug_layer (component)
+=======================
+
+The "debug_layer" is a mask that selects components of interest, e.g., a
+specific driver or part of the ACPI interpreter.  To build the debug_layer
+bitmask, look for the "#define _COMPONENT" in an ACPI source file.
+
+You can set the debug_layer mask at boot-time using the acpi.debug_layer
+command line argument, and you can change it after boot by writing values
+to /sys/module/acpi/parameters/debug_layer.
+
+The possible components are defined in include/acpi/acoutput.h and
+include/acpi/acpi_drivers.h.  Reading /sys/module/acpi/parameters/debug_layer
+shows the supported mask values, currently these::
+
+    ACPI_UTILITIES                  0x00000001
+    ACPI_HARDWARE                   0x00000002
+    ACPI_EVENTS                     0x00000004
+    ACPI_TABLES                     0x00000008
+    ACPI_NAMESPACE                  0x00000010
+    ACPI_PARSER                     0x00000020

+    ACPI_MEMORY_DEVICE_COMPONENT    0x08000000
+    ACPI_VIDEO_COMPONENT            0x10000000
+    ACPI_PROCESSOR_COMPONENT        0x20000000
+
+debug_level
+===========
+
+The "debug_level" is a mask that selects different types of messages, e.g.,
+those related to initialization, method execution, informational messages, etc.
+To build debug_level, look at the level specified in an ACPI_DEBUG_PRINT()
+statement.
+
+The ACPI interpreter uses several different levels, but the Linux
+ACPI core and ACPI drivers generally only use ACPI_LV_INFO.
+
+You can set the debug_level mask at boot-time using the acpi.debug_level
+command line argument, and you can change it after boot by writing values
+to /sys/module/acpi/parameters/debug_level.
+
+The possible levels are defined in include/acpi/acoutput.h.  Reading
+/sys/module/acpi/parameters/debug_level shows the supported mask values,
+currently these::
+
+    ACPI_LV_INIT                    0x00000001
+    ACPI_LV_DEBUG_OBJECT            0x00000002
+    ACPI_LV_INFO                    0x00000004
+    ACPI_LV_INIT_NAMES              0x00000020
+    ACPI_LV_PARSE                   0x00000040
+    ACPI_LV_LOAD                    0x00000080
+    ACPI_LV_DISPATCH                0x00000100
+    ACPI_LV_EXEC                    0x00000200

+    ACPI_LV_PACKAGE                 0x00040000
+    ACPI_LV_ALLOCATIONS             0x00100000
+    ACPI_LV_FUNCTIONS               0x00200000
+    ACPI_LV_OPTIMIZATIONS           0x00400000
+    ACPI_LV_MUTEX                   0x01000000

+    ACPI_LV_IO                      0x04000000
+    ACPI_LV_INTERRUPTS              0x08000000
+    ACPI_LV_AML_DISASSEMBLE         0x10000000
+    ACPI_LV_VERBOSE_INFO            0x20000000
+    ACPI_LV_FULL_TABLES             0x40000000
+    ACPI_LV_EVENTS                  0x80000000
+
+Examples
+========
+
+For example, drivers/acpi/bus.c contains this::
+
+    #define _COMPONENT              ACPI_BUS_COMPONENT
+    ...
+    ACPI_DEBUG_PRINT((ACPI_DB_INFO, "Device insertion detected\n"));
+
+To turn on this message, set the ACPI_BUS_COMPONENT bit in acpi.debug_layer
+and the ACPI_LV_INFO bit in acpi.debug_level.  (The ACPI_DEBUG_PRINT
+statement uses ACPI_DB_INFO, which is macro based on the ACPI_LV_INFO
+definition.)
+
+Enable all AML "Debug" output (stores to the Debug object while interpreting
+AML) during boot::
+
+    acpi.debug_layer=0xffffffff acpi.debug_level=0x2
+
+Enable PCI and PCI interrupt routing debug messages::
+
+    acpi.debug_layer=0x400000 acpi.debug_level=0x4
+
+Enable all ACPI hardware-related messages::
+
+    acpi.debug_layer=0x2 acpi.debug_level=0xffffffff
+
+Enable all ACPI_DB_INFO messages after boot::
+
+    # echo 0x4 > /sys/module/acpi/parameters/debug_level
+
+Show all valid component values::
+
+    # cat /sys/module/acpi/parameters/debug_layer

+Referencing hierarchical data nodes
+===================================
+
+:Copyright: |copy| 2018 Intel Corporation
+:Author: Sakari Ailus <sakari.ailus@linux.intel.com>
+
+ACPI in general allows referring to device objects in the tree only.
+Hierarchical data extension nodes may not be referred to directly, hence this
+document defines a scheme to implement such references.
+
+A reference consist of the device object name followed by one or more
+hierarchical data extension [1] keys. Specifically, the hierarchical data
+extension node which is referred to by the key shall lie directly under the
+parent object i.e. either the device object or another hierarchical data
+extension node.
+
+The keys in the hierarchical data nodes shall consist of the name of the node,
+"@" character and the number of the node in hexadecimal notation (without pre-
+or postfixes). The same ACPI object shall include the _DSD property extension
+with a property "reg" that shall have the same numerical value as the number of
+the node.
+
+In case a hierarchical data extensions node has no numerical value, then the
+"reg" property shall be omitted from the ACPI object's _DSD properties and the
+"@" character and the number shall be omitted from the hierarchical data
+extension key.
+
+
+Example
+=======
+
+In the ASL snippet below, the "reference" _DSD property [2] contains a
+device object reference to DEV0 and under that device object, a
+hierarchical data extension key "node@1" referring to the NOD1 object
+and lastly, a hierarchical data extension key "anothernode" referring to
+the ANOD object which is also the final target node of the reference.
+::
+
+	Device (DEV0)
+	{
+	    Name (_DSD, Package () {
+		ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"),
+		Package () {

+
+_DSD
+====
+
+_DSD (Device Specific Data) [7] is a predefined ACPI device
+configuration object that can be used to convey information on
+hardware features which are not specifically covered by the ACPI
+specification [1][6]. There are two _DSD extensions that are relevant
+for graphs: property [4] and hierarchical data extensions [5]. The
+property extension provides generic key-value pairs whereas the
+hierarchical data extension supports nodes with references to other
+nodes, forming a tree. The nodes in the tree may contain properties as
+defined by the property extension. The two extensions together provide
+a tree-like structure with zero or more properties (key-value pairs)
+in each node of the tree.
+
+The data structure may be accessed at runtime by using the device_*
+and fwnode_* functions defined in include/linux/fwnode.h .
+
+Fwnode represents a generic firmware node object. It is independent on
+the firmware type. In ACPI, fwnodes are _DSD hierarchical data
+extensions objects. A device's _DSD object is represented by an
+fwnode.
+
+The data structure may be referenced to elsewhere in the ACPI tables
+by using a hard reference to the device itself and an index to the
+hierarchical data extension array on each depth.
+
+
+Ports and endpoints
+===================
+
+The port and endpoint concepts are very similar to those in Devicetree
+[3]. A port represents an interface in a device, and an endpoint
+represents a connection to that interface.
+
+All port nodes are located under the device's "_DSD" node in the hierarchical
+data extension tree. The data extension related to each port node must begin
+with "port" and must be followed by the "@" character and the number of the
+port as its key. The target object it refers to should be called "PRTX", where
+"X" is the number of the port. An example of such a package would be::
+
+    Package() { "port@4", "PRT4" }
+
+Further on, endpoints are located under the port nodes. The hierarchical
+data extension key of the endpoint nodes must begin with
+"endpoint" and must be followed by the "@" character and the number of the
+endpoint. The object it refers to should be called "EPXY", where "X" is the
+number of the port and "Y" is the number of the endpoint. An example of such a
+package would be::
+
+    Package() { "endpoint@0", "EP40" }
+
+Each port node contains a property extension key "port", the value of which is
+the number of the port. Each endpoint is similarly numbered with a property
+extension key "reg", the value of which is the number of the endpoint. Port
+numbers must be unique within a device and endpoint numbers must be unique
+within a port. If a device object may only has a single port, then the number
+of that port shall be zero. Similarly, if a port may only have a single
+endpoint, the number of that endpoint shall be zero.
+
+The endpoint reference uses property extension with "remote-endpoint" property
+name followed by a reference in the same package. Such references consist of
+the remote device reference, the first package entry of the port data extension
+reference under the device and finally the first package entry of the endpoint
+data extension reference under the port. Individual references thus appear as::
+
+    Package() { device, "port@X", "endpoint@Y" }
+
+In the above example, "X" is the number of the port and "Y" is the number of
+the endpoint.
+
+The references to endpoints must be always done both ways, to the
+remote endpoint and back from the referred remote endpoint node.
+
+A simple example of this is show below::
+
+    Scope (\_SB.PCI0.I2C2)
+    {
+	Device (CAM0)
+	{
+	    Name (_DSD, Package () {
+		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+		Package () {
+		    Package () { "compatible", Package () { "nokia,smia" } },
+		},
+		ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"),
+		Package () {
+		    Package () { "port@0", "PRT0" },
+		}
+	    })
+	    Name (PRT0, Package() {
+		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+		Package () {
+		    Package () { "reg", 0 },
+		},
+		ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b"),

+		}
+	    })
+	    Name (EP00, Package() {
+		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+		Package () {
+		    Package () { "reg", 0 },
+		    Package () { "remote-endpoint", Package() { \_SB.PCI0.ISP, "port@4", "endpoint@0" } },
+		}
+	    })
+	}
+    }
+
+    Scope (\_SB.PCI0)
+    {
+	Device (ISP)
+	{
+	    Name (_DSD, Package () {

+		}
+	    })
+	}
+    }
+
+Here, the port 0 of the "CAM0" device is connected to the port 4 of

+_DSD Device Properties Usage Rules
+==================================
+
+Properties, Property Sets and Property Subsets
+==============================================
+
+The _DSD (Device Specific Data) configuration object, introduced in ACPI 5.1,
+allows any type of device configuration data to be provided via the ACPI
+namespace.  In principle, the format of the data may be arbitrary, but it has to
+be identified by a UUID which must be recognized by the driver processing the
+_DSD output.  However, there are generic UUIDs defined for _DSD recognized by
+the ACPI subsystem in the Linux kernel which automatically processes the data
+packages associated with them and makes those data available to device drivers
+as "device properties".
+
+A device property is a data item consisting of a string key and a value (of a
+specific type) associated with it.
+
+In the ACPI _DSD context it is an element of the sub-package following the
+generic Device Properties UUID in the _DSD return package as specified in the
+Device Properties UUID definition document [1]_.
+
+It also may be regarded as the definition of a key and the associated data type
+that can be returned by _DSD in the Device Properties UUID sub-package for a
+given device.
+
+A property set is a collection of properties applicable to a hardware entity
+like a device.  In the ACPI _DSD context it is the set of all properties that
+can be returned in the Device Properties UUID sub-package for the device in
+question.
+
+Property subsets are nested collections of properties.  Each of them is
+associated with an additional key (name) allowing the subset to be referred
+to as a whole (and to be treated as a separate entity).  The canonical
+representation of property subsets is via the mechanism specified in the
+Hierarchical Properties Extension UUID definition document [2]_.
+
+Property sets may be hierarchical.  That is, a property set may contain
+multiple property subsets that each may contain property subsets of its
+own and so on.
+
+General Validity Rule for Property Sets
+=======================================
+
+Valid property sets must follow the guidance given by the Device Properties UUID
+definition document [1].
+
+_DSD properties are intended to be used in addition to, and not instead of, the
+existing mechanisms defined by the ACPI specification.  Therefore, as a rule,
+they should only be used if the ACPI specification does not make direct
+provisions for handling the underlying use case.  It generally is invalid to
+return property sets which do not follow that rule from _DSD in data packages
+associated with the Device Properties UUID.
+
+Additional Considerations
+-------------------------
+
+There are cases in which, even if the general rule given above is followed in
+principle, the property set may still not be regarded as a valid one.
+
+For example, that applies to device properties which may cause kernel code
+(either a device driver or a library/subsystem) to access hardware in a way
+possibly leading to a conflict with AML methods in the ACPI namespace.  In
+particular, that may happen if the kernel code uses device properties to
+manipulate hardware normally controlled by ACPI methods related to power
+management, like _PSx and _DSW (for device objects) or _ON and _OFF (for power
+resource objects), or by ACPI device disabling/enabling methods, like _DIS and
+_SRS.
+
+In all cases in which kernel code may do something that will confuse AML as a
+result of using device properties, the device properties in question are not
+suitable for the ACPI environment and consequently they cannot belong to a valid
+property set.
+
+Property Sets and Device Tree Bindings
+======================================
+
+It often is useful to make _DSD return property sets that follow Device Tree
+bindings.
+
+In those cases, however, the above validity considerations must be taken into
+account in the first place and returning invalid property sets from _DSD must be
+avoided.  For this reason, it may not be possible to make _DSD return a property
+set following the given DT binding literally and completely.  Still, for the
+sake of code re-use, it may make sense to provide as much of the configuration
+data as possible in the form of device properties and complement that with an
+ACPI-specific mechanism suitable for the use case at hand.
+
+In any case, property sets following DT bindings literally should not be
+expected to automatically work in the ACPI environment regardless of their
+contents.

+=============================
+ACPI Based Device Enumeration
+=============================
+
+ACPI 5 introduced a set of new resources (UartTSerialBus, I2cSerialBus,
+SpiSerialBus, GpioIo and GpioInt) which can be used in enumerating slave
+devices behind serial bus controllers.
+
+In addition we are starting to see peripherals integrated in the
+SoC/Chipset to appear only in ACPI namespace. These are typically devices
+that are accessed through memory-mapped registers.
+
+In order to support this and re-use the existing drivers as much as
+possible we decided to do following:
+
+  - Devices that have no bus connector resource are represented as
+    platform devices.
+
+  - Devices behind real busses where there is a connector resource
+    are represented as struct spi_device or struct i2c_device
+    (standard UARTs are not busses so there is no struct uart_device).
+
+As both ACPI and Device Tree represent a tree of devices (and their
+resources) this implementation follows the Device Tree way as much as
+possible.
+
+The ACPI implementation enumerates devices behind busses (platform, SPI and
+I2C), creates the physical devices and binds them to their ACPI handle in
+the ACPI namespace.
+
+This means that when ACPI_HANDLE(dev) returns non-NULL the device was
+enumerated from ACPI namespace. This handle can be used to extract other
+device-specific configuration. There is an example of this below.
+
+Platform bus support
+====================
+
+Since we are using platform devices to represent devices that are not
+connected to any physical bus we only need to implement a platform driver
+for the device and add supported ACPI IDs. If this same IP-block is used on
+some other non-ACPI platform, the driver might work out of the box or needs
+some minor changes.
+
+Adding ACPI support for an existing driver should be pretty
+straightforward. Here is the simplest example::
+
+	#ifdef CONFIG_ACPI
+	static const struct acpi_device_id mydrv_acpi_match[] = {
+		/* ACPI IDs here */
+		{ }
+	};
+	MODULE_DEVICE_TABLE(acpi, mydrv_acpi_match);
+	#endif
+
+	static struct platform_driver my_driver = {
+		...
+		.driver = {
+			.acpi_match_table = ACPI_PTR(mydrv_acpi_match),
+		},
+	};
+
+If the driver needs to perform more complex initialization like getting and
+configuring GPIOs it can get its ACPI handle and extract this information
+from ACPI tables.
+
+DMA support
+===========
+
+DMA controllers enumerated via ACPI should be registered in the system to
+provide generic access to their resources. For example, a driver that would
+like to be accessible to slave devices via generic API call
+dma_request_slave_channel() must register itself at the end of the probe
+function like this::
+
+	err = devm_acpi_dma_controller_register(dev, xlate_func, dw);
+	/* Handle the error if it's not a case of !CONFIG_ACPI */
+
+and implement custom xlate function if needed (usually acpi_dma_simple_xlate()
+is enough) which converts the FixedDMA resource provided by struct
+acpi_dma_spec into the corresponding DMA channel. A piece of code for that case
+could look like::
+
+	#ifdef CONFIG_ACPI
+	struct filter_args {
+		/* Provide necessary information for the filter_func */
+		...
+	};
+
+	static bool filter_func(struct dma_chan *chan, void *param)
+	{
+		/* Choose the proper channel */
+		...
+	}
+
+	static struct dma_chan *xlate_func(struct acpi_dma_spec *dma_spec,
+			struct acpi_dma *adma)
+	{
+		dma_cap_mask_t cap;
+		struct filter_args args;
+
+		/* Prepare arguments for filter_func */
+		...
+		return dma_request_channel(cap, filter_func, &args);
+	}
+	#else
+	static struct dma_chan *xlate_func(struct acpi_dma_spec *dma_spec,
+			struct acpi_dma *adma)
+	{
+		return NULL;
+	}
+	#endif
+
+dma_request_slave_channel() will call xlate_func() for each registered DMA
+controller. In the xlate function the proper channel must be chosen based on
+information in struct acpi_dma_spec and the properties of the controller
+provided by struct acpi_dma.
+
+Clients must call dma_request_slave_channel() with the string parameter that
+corresponds to a specific FixedDMA resource. By default "tx" means the first
+entry of the FixedDMA resource array, "rx" means the second entry. The table
+below shows a layout::
+
+	Device (I2C0)
+	{
+		...
+		Method (_CRS, 0, NotSerialized)
+		{
+			Name (DBUF, ResourceTemplate ()
+			{
+				FixedDMA (0x0018, 0x0004, Width32bit, _Y48)
+				FixedDMA (0x0019, 0x0005, Width32bit, )
+			})
+		...
+		}
+	}
+
+So, the FixedDMA with request line 0x0018 is "tx" and next one is "rx" in
+this example.
+
+In robust cases the client unfortunately needs to call
+acpi_dma_request_slave_chan_by_index() directly and therefore choose the
+specific FixedDMA resource by its index.
+
+SPI serial bus support
+======================
+
+Slave devices behind SPI bus have SpiSerialBus resource attached to them.
+This is extracted automatically by the SPI core and the slave devices are
+enumerated once spi_register_master() is called by the bus driver.
+
+Here is what the ACPI namespace for a SPI slave might look like::
+
+	Device (EEP0)
+	{
+		Name (_ADR, 1)
+		Name (_CID, Package() {
+			"ATML0025",
+			"AT25",
+		})
+		...
+		Method (_CRS, 0, NotSerialized)
+		{
+			SPISerialBus(1, PolarityLow, FourWireMode, 8,
+				ControllerInitiated, 1000000, ClockPolarityLow,
+				ClockPhaseFirst, "\\_SB.PCI0.SPI1",)
+		}
+		...
+
+The SPI device drivers only need to add ACPI IDs in a similar way than with
+the platform device drivers. Below is an example where we add ACPI support
+to at25 SPI eeprom driver (this is meant for the above ACPI snippet)::
+
+	#ifdef CONFIG_ACPI
+	static const struct acpi_device_id at25_acpi_match[] = {
+		{ "AT25", 0 },
+		{ },
+	};
+	MODULE_DEVICE_TABLE(acpi, at25_acpi_match);
+	#endif
+
+	static struct spi_driver at25_driver = {
+		.driver = {
+			...
+			.acpi_match_table = ACPI_PTR(at25_acpi_match),
+		},
+	};
+
+Note that this driver actually needs more information like page size of the
+eeprom etc. but at the time writing this there is no standard way of
+passing those. One idea is to return this in _DSM method like::
+
+	Device (EEP0)
+	{
+		...
+		Method (_DSM, 4, NotSerialized)
+		{
+			Store (Package (6)
+			{
+				"byte-len", 1024,
+				"addr-mode", 2,
+				"page-size, 32
+			}, Local0)
+
+			// Check UUIDs etc.
+
+			Return (Local0)
+		}
+
+Then the at25 SPI driver can get this configuration by calling _DSM on its
+ACPI handle like::
+
+	struct acpi_buffer output = { ACPI_ALLOCATE_BUFFER, NULL };
+	struct acpi_object_list input;
+	acpi_status status;
+
+	/* Fill in the input buffer */
+
+	status = acpi_evaluate_object(ACPI_HANDLE(&spi->dev), "_DSM",
+				      &input, &output);
+	if (ACPI_FAILURE(status))
+		/* Handle the error */
+
+	/* Extract the data here */
+
+	kfree(output.pointer);
+
+I2C serial bus support
+======================
+
+The slaves behind I2C bus controller only need to add the ACPI IDs like
+with the platform and SPI drivers. The I2C core automatically enumerates
+any slave devices behind the controller device once the adapter is
+registered.
+
+Below is an example of how to add ACPI support to the existing mpu3050
+input driver::
+
+	#ifdef CONFIG_ACPI
+	static const struct acpi_device_id mpu3050_acpi_match[] = {
+		{ "MPU3050", 0 },
+		{ },
+	};
+	MODULE_DEVICE_TABLE(acpi, mpu3050_acpi_match);
+	#endif
+
+	static struct i2c_driver mpu3050_i2c_driver = {
+		.driver	= {
+			.name	= "mpu3050",
+			.owner	= THIS_MODULE,
+			.pm	= &mpu3050_pm,
+			.of_match_table = mpu3050_of_match,
+			.acpi_match_table = ACPI_PTR(mpu3050_acpi_match),
+		},
+		.probe		= mpu3050_probe,
+		.remove		= mpu3050_remove,
+		.id_table	= mpu3050_ids,
+	};
+
+GPIO support
+============
+
+ACPI 5 introduced two new resources to describe GPIO connections: GpioIo
+and GpioInt. These resources can be used to pass GPIO numbers used by
+the device to the driver. ACPI 5.1 extended this with _DSD (Device
+Specific Data) which made it possible to name the GPIOs among other things.
+
+For example::
+
+	Device (DEV)
+	{
+		Method (_CRS, 0, NotSerialized)
+		{
+			Name (SBUF, ResourceTemplate()
+			{
+				...
+				// Used to power on/off the device
+				GpioIo (Exclusive, PullDefault, 0x0000, 0x0000,
+					IoRestrictionOutputOnly, "\\_SB.PCI0.GPI0",
+					0x00, ResourceConsumer,,)
+				{
+					// Pin List
+					0x0055
+				}
+
+				// Interrupt for the device
+				GpioInt (Edge, ActiveHigh, ExclusiveAndWake, PullNone,
+					0x0000, "\\_SB.PCI0.GPI0", 0x00, ResourceConsumer,,)
+				{
+					// Pin list
+					0x0058
+				}
+
+				...
+
+			}
+
+			Return (SBUF)
+		}
+
+		// ACPI 5.1 _DSD used for naming the GPIOs
+		Name (_DSD, Package ()
+		{
+			ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+			Package ()
+			{
+				Package () {"power-gpios", Package() {^DEV, 0, 0, 0 }},
+				Package () {"irq-gpios", Package() {^DEV, 1, 0, 0 }},
+			}
+		})
+		...
+
+These GPIO numbers are controller relative and path "\\_SB.PCI0.GPI0"
+specifies the path to the controller. In order to use these GPIOs in Linux
+we need to translate them to the corresponding Linux GPIO descriptors.
+
+There is a standard GPIO API for that and is documented in
+Documentation/gpio/.
+
+In the above example we can get the corresponding two GPIO descriptors with
+a code like this::
+
+	#include <linux/gpio/consumer.h>
+	...
+
+	struct gpio_desc *irq_desc, *power_desc;
+
+	irq_desc = gpiod_get(dev, "irq");
+	if (IS_ERR(irq_desc))
+		/* handle error */
+
+	power_desc = gpiod_get(dev, "power");
+	if (IS_ERR(power_desc))
+		/* handle error */
+
+	/* Now we can use the GPIO descriptors */
+
+There are also devm_* versions of these functions which release the
+descriptors once the device is released.
+
+See Documentation/acpi/gpio-properties.txt for more information about the
+_DSD binding related to GPIOs.
+
+MFD devices
+===========
+
+The MFD devices register their children as platform devices. For the child
+devices there needs to be an ACPI handle that they can use to reference
+parts of the ACPI namespace that relate to them. In the Linux MFD subsystem
+we provide two ways:
+
+  - The children share the parent ACPI handle.
+  - The MFD cell can specify the ACPI id of the device.
+
+For the first case, the MFD drivers do not need to do anything. The
+resulting child platform device will have its ACPI_COMPANION() set to point
+to the parent device.
+
+If the ACPI namespace has a device that we can match using an ACPI id or ACPI
+adr, the cell should be set like::
+
+	static struct mfd_cell_acpi_match my_subdevice_cell_acpi_match = {
+		.pnpid = "XYZ0001",
+		.adr = 0,
+	};
+
+	static struct mfd_cell my_subdevice_cell = {
+		.name = "my_subdevice",
+		/* set the resources relative to the parent */
+		.acpi_match = &my_subdevice_cell_acpi_match,
+	};
+
+The ACPI id "XYZ0001" is then used to lookup an ACPI device directly under
+the MFD device and if found, that ACPI companion device is bound to the
+resulting child platform device.
+
+Device Tree namespace link device ID
+====================================
+
+The Device Tree protocol uses device identification based on the "compatible"
+property whose value is a string or an array of strings recognized as device
+identifiers by drivers and the driver core.  The set of all those strings may be
+regarded as a device identification namespace analogous to the ACPI/PNP device
+ID namespace.  Consequently, in principle it should not be necessary to allocate
+a new (and arguably redundant) ACPI/PNP device ID for a devices with an existing
+identification string in the Device Tree (DT) namespace, especially if that ID
+is only needed to indicate that a given device is compatible with another one,
+presumably having a matching driver in the kernel already.
+
+In ACPI, the device identification object called _CID (Compatible ID) is used to
+list the IDs of devices the given one is compatible with, but those IDs must
+belong to one of the namespaces prescribed by the ACPI specification (see
+Section 6.1.2 of ACPI 6.0 for details) and the DT namespace is not one of them.
+Moreover, the specification mandates that either a _HID or an _ADR identification
+object be present for all ACPI objects representing devices (Section 6.1 of ACPI
+6.0).  For non-enumerable bus types that object must be _HID and its value must
+be a device ID from one of the namespaces prescribed by the specification too.
+
+The special DT namespace link device ID, PRP0001, provides a means to use the
+existing DT-compatible device identification in ACPI and to satisfy the above
+requirements following from the ACPI specification at the same time.  Namely,
+if PRP0001 is returned by _HID, the ACPI subsystem will look for the
+"compatible" property in the device object's _DSD and will use the value of that
+property to identify the corresponding device in analogy with the original DT
+device identification algorithm.  If the "compatible" property is not present
+or its value is not valid, the device will not be enumerated by the ACPI
+subsystem.  Otherwise, it will be enumerated automatically as a platform device
+(except when an I2C or SPI link from the device to its parent is present, in
+which case the ACPI core will leave the device enumeration to the parent's
+driver) and the identification strings from the "compatible" property value will
+be used to find a driver for the device along with the device IDs listed by _CID
+(if present).
+
+Analogously, if PRP0001 is present in the list of device IDs returned by _CID,
+the identification strings listed by the "compatible" property value (if present
+and valid) will be used to look for a driver matching the device, but in that
+case their relative priority with respect to the other device IDs listed by
+_HID and _CID depends on the position of PRP0001 in the _CID return package.
+Specifically, the device IDs returned by _HID and preceding PRP0001 in the _CID
+return package will be checked first.  Also in that case the bus type the device
+will be enumerated to depends on the device ID returned by _HID.
+
+For example, the following ACPI sample might be used to enumerate an lm75-type
+I2C temperature sensor and match it to the driver using the Device Tree
+namespace link::
+
+	Device (TMP0)
+	{
+		Name (_HID, "PRP0001")
+		Name (_DSD, Package() {
+			ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+			Package () {
+				Package (2) { "compatible", "ti,tmp75" },
+			}
+		})
+		Method (_CRS, 0, Serialized)
+		{
+			Name (SBUF, ResourceTemplate ()
+			{
+				I2cSerialBusV2 (0x48, ControllerInitiated,
+					400000, AddressingMode7Bit,
+					"\\_SB.PCI0.I2C1", 0x00,
+					ResourceConsumer, , Exclusive,)
+			})
+			Return (SBUF)
+		}
+	}
+
+It is valid to define device objects with a _HID returning PRP0001 and without
+the "compatible" property in the _DSD or a _CID as long as one of their
+ancestors provides a _DSD with a valid "compatible" property.  Such device
+objects are then simply regarded as additional "blocks" providing hierarchical
+configuration information to the driver of the composite ancestor device.
+
+However, PRP0001 can only be returned from either _HID or _CID of a device
+object if all of the properties returned by the _DSD associated with it (either
+the _DSD of the device object itself or the _DSD of its ancestor in the
+"composite device" case described above) can be used in the ACPI environment.
+Otherwise, the _DSD itself is regarded as invalid and therefore the "compatible"
+property returned by it is meaningless.
+
+Refer to :doc:`DSD-properties-rules` for more information.

+_DSD Device Properties Related to GPIO
+======================================
+
+With the release of ACPI 5.1, the _DSD configuration object finally
+allows names to be given to GPIOs (and other things as well) returned
+by _CRS.  Previously, we were only able to use an integer index to find
+the corresponding GPIO, which is pretty error prone (it depends on
+the _CRS output ordering, for example).
+
+With _DSD we can now query GPIOs using a name instead of an integer
+index, like the ASL example below shows::
+
+  // Bluetooth device with reset and shutdown GPIOs
+  Device (BTH)
+  {
+      Name (_HID, ...)
+
+      Name (_CRS, ResourceTemplate ()
+      {
+          GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
+                  "\\_SB.GPO0", 0, ResourceConsumer) {15}
+          GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
+                  "\\_SB.GPO0", 0, ResourceConsumer) {27, 31}
+      })
+
+      Name (_DSD, Package ()
+      {
+          ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+          Package ()
+	  {
+              Package () {"reset-gpios", Package() {^BTH, 1, 1, 0 }},
+              Package () {"shutdown-gpios", Package() {^BTH, 0, 0, 0 }},
+          }
+      })
+  }
+
+The format of the supported GPIO property is::
+
+  Package () { "name", Package () { ref, index, pin, active_low }}
+
+ref
+  The device that has _CRS containing GpioIo()/GpioInt() resources,
+  typically this is the device itself (BTH in our case).
+index
+  Index of the GpioIo()/GpioInt() resource in _CRS starting from zero.
+pin
+  Pin in the GpioIo()/GpioInt() resource. Typically this is zero.
+active_low
+  If 1 the GPIO is marked as active_low.
+
+Since ACPI GpioIo() resource does not have a field saying whether it is
+active low or high, the "active_low" argument can be used here.  Setting
+it to 1 marks the GPIO as active low.
+
+In our Bluetooth example the "reset-gpios" refers to the second GpioIo()
+resource, second pin in that resource with the GPIO number of 31.
+
+It is possible to leave holes in the array of GPIOs. This is useful in
+cases like with SPI host controllers where some chip selects may be
+implemented as GPIOs and some as native signals. For example a SPI host
+controller can have chip selects 0 and 2 implemented as GPIOs and 1 as
+native::
+
+  Package () {
+      "cs-gpios",
+      Package () {
+          ^GPIO, 19, 0, 0, // chip select 0: GPIO
+          0,               // chip select 1: native signal
+          ^GPIO, 20, 0, 0, // chip select 2: GPIO
+      }
+  }
+
+Other supported properties

+
+Following Device Tree compatible device properties are also supported by
+_DSD device properties for GPIO controllers:
+

+      }
+  })
+
+  Name (G8PU, Package () {
+      ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+      Package () {
+          Package () {"gpio-hog", 1},
+          Package () {"gpios", Package () {8, 0}},
+          Package () {"output-high", 1},
+          Package () {"line-name", "gpio8-pullup"},
+      }
+  })
+
+- gpio-line-names
+
+Example::
+
+  Package () {
+      "gpio-line-names",
+      Package () {
+          "SPI0_CS_N", "EXP2_INT", "MUX6_IO", "UART0_RXD", "MUX7_IO",
+          "LVL_C_A1", "MUX0_IO", "SPI1_MISO"
+      }
+  }
+
+See Documentation/devicetree/bindings/gpio/gpio.txt for more information
+about these properties.
+
+ACPI GPIO Mappings Provided by Drivers
+======================================
+
+There are systems in which the ACPI tables do not contain _DSD but provide _CRS
+with GpioIo()/GpioInt() resources and device drivers still need to work with
+them.
+
+In those cases ACPI device identification objects, _HID, _CID, _CLS, _SUB, _HRV,
+available to the driver can be used to identify the device and that is supposed
+to be sufficient to determine the meaning and purpose of all of the GPIO lines
+listed by the GpioIo()/GpioInt() resources returned by _CRS.  In other words,
+the driver is supposed to know what to use the GpioIo()/GpioInt() resources for
+once it has identified the device.  Having done that, it can simply assign names
+to the GPIO lines it is going to use and provide the GPIO subsystem with a
+mapping between those names and the ACPI GPIO resources corresponding to them.
+
+To do that, the driver needs to define a mapping table as a NULL-terminated
+array of struct acpi_gpio_mapping objects that each contain a name, a pointer
+to an array of line data (struct acpi_gpio_params) objects and the size of that
+array.  Each struct acpi_gpio_params object consists of three fields,
+crs_entry_index, line_index, active_low, representing the index of the target
+GpioIo()/GpioInt() resource in _CRS starting from zero, the index of the target
+line in that resource starting from zero, and the active-low flag for that line,
+respectively, in analogy with the _DSD GPIO property format specified above.
+
+For the example Bluetooth device discussed previously the data structures in
+question would look like this::
+
+  static const struct acpi_gpio_params reset_gpio = { 1, 1, false };
+  static const struct acpi_gpio_params shutdown_gpio = { 0, 0, false };
+
+  static const struct acpi_gpio_mapping bluetooth_acpi_gpios[] = {
+    { "reset-gpios", &reset_gpio, 1 },
+    { "shutdown-gpios", &shutdown_gpio, 1 },
+    { },
+  };
+
+Next, the mapping table needs to be passed as the second argument to
+acpi_dev_add_driver_gpios() that will register it with the ACPI device object
+pointed to by its first argument.  That should be done in the driver's .probe()
+routine.  On removal, the driver should unregister its GPIO mapping table by
+calling acpi_dev_remove_driver_gpios() on the ACPI device object where that
+table was previously registered.
+
+Using the _CRS fallback
+=======================
+
+If a device does not have _DSD or the driver does not create ACPI GPIO
+mapping, the Linux GPIO framework refuses to return any GPIOs. This is
+because the driver does not know what it actually gets. For example if we
+have a device like below::
+
+  Device (BTH)
+  {
+      Name (_HID, ...)
+
+      Name (_CRS, ResourceTemplate () {
+          GpioIo (Exclusive, PullNone, 0, 0, IoRestrictionNone,
+                  "\\_SB.GPO0", 0, ResourceConsumer) {15}
+          GpioIo (Exclusive, PullNone, 0, 0, IoRestrictionNone,
+                  "\\_SB.GPO0", 0, ResourceConsumer) {27}
+      })
+  }
+
+The driver might expect to get the right GPIO when it does::
+
+  desc = gpiod_get(dev, "reset", GPIOD_OUT_LOW);
+
+but since there is no way to know the mapping between "reset" and
+the GpioIo() in _CRS desc will hold ERR_PTR(-ENOENT).
+
+The driver author can solve this by passing the mapping explictly
+(the recommended way and documented in the above chapter).
+
+The ACPI GPIO mapping tables should not contaminate drivers that are not
+knowing about which exact device they are servicing on. It implies that
+the ACPI GPIO mapping tables are hardly linked to ACPI ID and certain
+objects, as listed in the above chapter, of the device in question.
+
+Getting GPIO descriptor
+=======================
+
+There are two main approaches to get GPIO resource from ACPI::
+
+  desc = gpiod_get(dev, connection_id, flags);
+  desc = gpiod_get_index(dev, connection_id, index, flags);
+
+We may consider two different cases here, i.e. when connection ID is
+provided and otherwise.
+
+Case 1::
+
+  desc = gpiod_get(dev, "non-null-connection-id", flags);
+  desc = gpiod_get_index(dev, "non-null-connection-id", index, flags);
+
+Case 2::
+
+  desc = gpiod_get(dev, NULL, flags);
+  desc = gpiod_get_index(dev, NULL, index, flags);
+
+Case 1 assumes that corresponding ACPI device description must have
+defined device properties and will prevent to getting any GPIO resources
+otherwise.
+
+Case 2 explicitly tells GPIO core to look for resources in _CRS.
+
+Be aware that gpiod_get_index() in cases 1 and 2, assuming that there
+are two versions of ACPI device description provided and no mapping is
+present in the driver, will return different resources. That's why a
+certain driver has to handle them carefully as explained in previous
+chapter.

+Low Power Idle Table (LPIT)
+===========================
+
+To enumerate platform Low Power Idle states, Intel platforms are using
+“Low Power Idle Table” (LPIT). More details about this table can be
+downloaded from:
+http://www.uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf
+
+Residencies for each low power state can be read via FFH
+(Function fixed hardware) or a memory mapped interface.
+
+On platforms supporting S0ix sleep states, there can be two types of
+residencies:
+
+  - CPU PKG C10 (Read via FFH interface)
+  - Platform Controller Hub (PCH) SLP_S0 (Read via memory mapped interface)
+
+The following attributes are added dynamically to the cpuidle
+sysfs attribute group::
+
+  /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
+  /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us
+
+The "low_power_idle_cpu_residency_us" attribute shows time spent
+by the CPU package in PKG C10
+
+The "low_power_idle_system_residency_us" attribute shows SLP_S0
+residency, or system time spent with the SLP_S0# signal asserted.
+This is the lowest possible system power state, achieved only when CPU is in
+PKG C10 and all functional blocks in PCH are in a low power state.

+=======================================
+Linux ACPI Custom Control Method How To
+=======================================
+
+:Author: Zhang Rui <rui.zhang@intel.com>
+
+
+Linux supports customizing ACPI control methods at runtime.
+
+Users can use this to:
+
+1. override an existing method which may not work correctly,
+   or just for debugging purposes.
+2. insert a completely new method in order to create a missing
+   method such as _OFF, _ON, _STA, _INI, etc.
+
+For these cases, it is far simpler to dynamically install a single
+control method rather than override the entire DSDT, because kernel
+rebuild/reboot is not needed and test result can be got in minutes.
+
+.. note::
+
+  - Only ACPI METHOD can be overridden, any other object types like
+    "Device", "OperationRegion", are not recognized. Methods
+    declared inside scope operators are also not supported.
+
+  - The same ACPI control method can be overridden for many times,
+    and it's always the latest one that used by Linux/kernel.
+
+  - To get the ACPI debug object output (Store (AAAA, Debug)),
+    please run::
+
+      echo 1 > /sys/module/acpi/parameters/aml_debug_output
+
+
+1. override an existing method
+==============================
+a) get the ACPI table via ACPI sysfs I/F. e.g. to get the DSDT,
+   just run "cat /sys/firmware/acpi/tables/DSDT > /tmp/dsdt.dat"
+b) disassemble the table by running "iasl -d dsdt.dat".
+c) rewrite the ASL code of the method and save it in a new file,
+d) package the new file (psr.asl) to an ACPI table format.
+   Here is an example of a customized \_SB._AC._PSR method::
+
+      DefinitionBlock ("", "SSDT", 1, "", "", 0x20080715)
+      {
+         Method (\_SB_.AC._PSR, 0, NotSerialized)
+         {
+            Store ("In AC _PSR", Debug)
+            Return (ACON)
+         }
+      }
+
+   Note that the full pathname of the method in ACPI namespace
+   should be used.
+e) assemble the file to generate the AML code of the method.
+   e.g. "iasl -vw 6084 psr.asl" (psr.aml is generated as a result)
+   If parameter "-vw 6084" is not supported by your iASL compiler,
+   please try a newer version.
+f) mount debugfs by "mount -t debugfs none /sys/kernel/debug"
+g) override the old method via the debugfs by running
+   "cat /tmp/psr.aml > /sys/kernel/debug/acpi/custom_method"
+
+2. insert a new method
+======================
+This is easier than overriding an existing method.
+We just need to create the ASL code of the method we want to
+insert and then follow the step c) ~ g) in section 1.
+
+3. undo your changes
+====================
+The "undo" operation is not supported for a new inserted method
+right now, i.e. we can not remove a method currently.
+For an overridden method, in order to undo your changes, please
+save a copy of the method original ASL code in step c) section 1,
+and redo step c) ~ g) to override the method with the original one.
+
+
+.. note:: We can use a kernel with multiple custom ACPI method running,
+   But each individual write to debugfs can implement a SINGLE
+   method override. i.e. if we want to insert/override multiple
+   ACPI methods, we need to redo step c) ~ g) for multiple times.
+
+.. note:: Be aware that root can mis-use this driver to modify arbitrary
+   memory and gain additional rights, if root's privileges got
+   restricted (for example if root is not allowed to load additional
+   modules after boot).

+=====================
+ACPICA Trace Facility
+=====================
+
+:Copyright: |copy| 2015, Intel Corporation
+:Author: Lv Zheng <lv.zheng@intel.com>
+
+
+Abstract
+========
+This document describes the functions and the interfaces of the
+method tracing facility.
+
+Functionalities and usage examples
+==================================
+
+ACPICA provides method tracing capability. And two functions are
+currently implemented using this capability.
+
+Log reducer
+-----------
+
+ACPICA subsystem provides debugging outputs when CONFIG_ACPI_DEBUG is
+enabled. The debugging messages which are deployed via
+ACPI_DEBUG_PRINT() macro can be reduced at 2 levels - per-component
+level (known as debug layer, configured via
+/sys/module/acpi/parameters/debug_layer) and per-type level (known as
+debug level, configured via /sys/module/acpi/parameters/debug_level).
+
+But when the particular layer/level is applied to the control method
+evaluations, the quantity of the debugging outputs may still be too
+large to be put into the kernel log buffer. The idea thus is worked out
+to only enable the particular debug layer/level (normally more detailed)
+logs when the control method evaluation is started, and disable the
+detailed logging when the control method evaluation is stopped.
+
+The following command examples illustrate the usage of the "log reducer"
+functionality:
+
+a. Filter out the debug layer/level matched logs when control methods
+   are being evaluated::
+
+      # cd /sys/module/acpi/parameters
+      # echo "0xXXXXXXXX" > trace_debug_layer
+      # echo "0xYYYYYYYY" > trace_debug_level
+      # echo "enable" > trace_state
+
+b. Filter out the debug layer/level matched logs when the specified
+   control method is being evaluated::
+
+      # cd /sys/module/acpi/parameters
+      # echo "0xXXXXXXXX" > trace_debug_layer
+      # echo "0xYYYYYYYY" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "method" > /sys/module/acpi/parameters/trace_state
+
+c. Filter out the debug layer/level matched logs when the specified
+   control method is being evaluated for the first time::
+
+      # cd /sys/module/acpi/parameters
+      # echo "0xXXXXXXXX" > trace_debug_layer
+      # echo "0xYYYYYYYY" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "method-once" > /sys/module/acpi/parameters/trace_state
+
+Where:
+   0xXXXXXXXX/0xYYYYYYYY
+     Refer to Documentation/acpi/debug.txt for possible debug layer/level
+     masking values.
+   \PPPP.AAAA.TTTT.HHHH
+     Full path of a control method that can be found in the ACPI namespace.
+     It needn't be an entry of a control method evaluation.
+
+AML tracer
+----------
+
+There are special log entries added by the method tracing facility at
+the "trace points" the AML interpreter starts/stops to execute a control
+method, or an AML opcode. Note that the format of the log entries are
+subject to change::
+
+   [    0.186427]   exdebug-0398 ex_trace_point        : Method Begin [0xf58394d8:\_SB.PCI0.LPCB.ECOK] execution.

+
+Developers can utilize these special log entries to track the AML
+interpretion, thus can aid issue debugging and performance tuning. Note
+that, as the "AML tracer" logs are implemented via ACPI_DEBUG_PRINT()
+macro, CONFIG_ACPI_DEBUG is also required to be enabled for enabling
+"AML tracer" logs.
+
+The following command examples illustrate the usage of the "AML tracer"
+functionality:
+
+a. Filter out the method start/stop "AML tracer" logs when control
+   methods are being evaluated::
+
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "enable" > trace_state
+
+b. Filter out the method start/stop "AML tracer" when the specified
+   control method is being evaluated::
+
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "method" > trace_state
+
+c. Filter out the method start/stop "AML tracer" logs when the specified
+   control method is being evaluated for the first time::
+
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "method-once" > trace_state
+
+d. Filter out the method/opcode start/stop "AML tracer" when the
+   specified control method is being evaluated::
+
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "opcode" > trace_state
+
+e. Filter out the method/opcode start/stop "AML tracer" when the
+   specified control method is being evaluated for the first time::
+
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "opcode-opcode" > trace_state
+
+Note that all above method tracing facility related module parameters can
+be used as the boot parameters, for example::
+
+   acpi.trace_debug_layer=0x80 acpi.trace_debug_level=0x10 \
+   acpi.trace_method_name=\_SB.LID0._LID acpi.trace_state=opcode-once
+
+
+Interface descriptions
+======================
+
+All method tracing functions can be configured via ACPI module
+parameters that are accessible at /sys/module/acpi/parameters/:
+
+trace_method_name
+  The full path of the AML method that the user wants to trace.
+
+  Note that the full path shouldn't contain the trailing "_"s in its
+  name segments but may contain "\" to form an absolute path.
+
+trace_debug_layer
+  The temporary debug_layer used when the tracing feature is enabled.
+
+  Using ACPI_EXECUTER (0x80) by default, which is the debug_layer
+  used to match all "AML tracer" logs.
+
+trace_debug_level
+  The temporary debug_level used when the tracing feature is enabled.
+
+  Using ACPI_LV_TRACE_POINT (0x10) by default, which is the
+  debug_level used to match all "AML tracer" logs.
+
+trace_state
+  The status of the tracing feature.
+
+  Users can enable/disable this debug tracing feature by executing
+  the following command::
+
+   # echo string > /sys/module/acpi/parameters/trace_state
+
+Where "string" should be one of the following:
+
+"disable"
+  Disable the method tracing feature.
+
+"enable"
+  Enable the method tracing feature.
+  
+  ACPICA debugging messages matching "trace_debug_layer/trace_debug_level"
+  during any method execution will be logged.
+
+"method"
+  Enable the method tracing feature.
+
+  ACPICA debugging messages matching "trace_debug_layer/trace_debug_level"
+  during method execution of "trace_method_name" will be logged.
+
+"method-once"
+  Enable the method tracing feature.
+
+  ACPICA debugging messages matching "trace_debug_layer/trace_debug_level"
+  during method execution of "trace_method_name" will be logged only once.
+
+"opcode"
+  Enable the method tracing feature.
+
+  ACPICA debugging messages matching "trace_debug_layer/trace_debug_level"
+  during method/opcode execution of "trace_method_name" will be logged.
+
+"opcode-once"
+  Enable the method tracing feature.
+
+  ACPICA debugging messages matching "trace_debug_layer/trace_debug_level"
+  during method/opcode execution of "trace_method_name" will be logged only
+  once.
+
+Note that, the difference between the "enable" and other feature
+enabling options are:
+
+1. When "enable" is specified, since
+   "trace_debug_layer/trace_debug_level" shall apply to all control
+   method evaluations, after configuring "trace_state" to "enable",
+   "trace_method_name" will be reset to NULL.
+2. When "method/opcode" is specified, if
+   "trace_method_name" is NULL when "trace_state" is configured to
+   these options, the "trace_debug_layer/trace_debug_level" will
+   apply to all control method evaluations.

+Abstract
+========
+The Linux ACPI subsystem converts ACPI namespace objects into a Linux
+device tree under the /sys/devices/LNXSYSTEM:00 and updates it upon
+receiving ACPI hotplug notification events.  For each device object
+in this hierarchy there is a corresponding symbolic link in the
+/sys/bus/acpi/devices.
+
+This document illustrates the structure of the ACPI device tree.
+
+ACPI Definition Blocks
+======================
+
+The ACPI firmware sets up RSDP (Root System Description Pointer) in the
+system memory address space pointing to the XSDT (Extended System
+Description Table).  The XSDT always points to the FADT (Fixed ACPI
+Description Table) using its first entry, the data within the FADT
+includes various fixed-length entries that describe fixed ACPI features
+of the hardware.  The FADT contains a pointer to the DSDT
+(Differentiated System Descripition Table).  The XSDT also contains
+entries pointing to possibly multiple SSDTs (Secondary System
+Description Table).
+
+The DSDT and SSDT data is organized in data structures called definition
+blocks that contain definitions of various objects, including ACPI
+control methods, encoded in AML (ACPI Machine Language).  The data block
+of the DSDT along with the contents of SSDTs represents a hierarchical
+data structure called the ACPI namespace whose topology reflects the
+structure of the underlying hardware platform.
+
+The relationships between ACPI System Definition Tables described above
+are illustrated in the following diagram::
+

+
+                  Figure 1. ACPI Definition Blocks
+
+.. note:: RSDP can also contain a pointer to the RSDT (Root System
+   Description Table).  Platforms provide RSDT to enable
+   compatibility with ACPI 1.0 operating systems.  The OS is expected
+   to use XSDT, if present.
+
+
+Example ACPI Namespace
+======================
+
+All definition blocks are loaded into a single namespace.  The namespace
+is a hierarchy of objects identified by names and paths.
+The following naming conventions apply to object names in the ACPI
+namespace:
+
+   1. All names are 32 bits long.
+   2. The first byte of a name must be one of 'A' - 'Z', '_'.
+   3. Each of the remaining bytes of a name must be one of 'A' - 'Z', '0'
+      - '9', '_'.
+   4. Names starting with '_' are reserved by the ACPI specification.
+   5. The '\' symbol represents the root of the namespace (i.e. names
+      prepended with '\' are relative to the namespace root).
+   6. The '^' symbol represents the parent of the current namespace node
+      (i.e. names prepended with '^' are relative to the parent of the
+      current namespace node).
+
+The figure below shows an example ACPI namespace::

+Linux ACPI Device Objects
+=========================
+
+The Linux kernel's core ACPI subsystem creates struct acpi_device
+objects for ACPI namespace objects representing devices, power resources
+processors, thermal zones.  Those objects are exported to user space via
+sysfs as directories in the subtree under /sys/devices/LNXSYSTM:00.  The
+format of their names is <bus_id:instance>, where 'bus_id' refers to the
+ACPI namespace representation of the given object and 'instance' is used
+for distinguishing different object of the same 'bus_id' (it is
+two-digit decimal representation of an unsigned integer).
+
+The value of 'bus_id' depends on the type of the object whose name it is
+part of as listed in the table below::
+
+                +---+-----------------+-------+----------+
+                |   | Object/Feature  | Table | bus_id   |
+                +---+-----------------+-------+----------+

+                +---+-----------------+-------+----------+
+                | N | Processor       | xSDT  | LNXCPU   |

+                | M | ATA Controller  | xSDT  | LNXIOBAY |
+                +---+-----------------+-------+----------+
+                | M | Docking Station | xSDT  | LNXDOCK  |
+                +---+-----------------+-------+----------+
+
+                 Table 1. ACPI Namespace Objects Mapping
+
+The following rules apply when creating struct acpi_device objects on
+the basis of the contents of ACPI System Description Tables (as
+indicated by the letter in the first column and the notation in the
+second column of the table above):
+
+   N:
+      The object's source is an ACPI namespace node (as indicated by the
+      named object's type in the second column).  In that case the object's
+      directory in sysfs will contain the 'path' attribute whose value is
+      the full path to the node from the namespace root.
+   F:
+      The struct acpi_device object is created for a fixed hardware
+      feature (as indicated by the fixed feature flag's name in the second
+      column), so its sysfs directory will not contain the 'path'
+      attribute.
+   M:
+      The struct acpi_device object is created for an ACPI namespace node
+      with specific control methods (as indicated by the ACPI defined
+      device's type in the second column).  The 'path' attribute containing
+      its namespace path will be present in its sysfs directory.  For
+      example, if the _BCL method is present for an ACPI namespace node, a
+      struct acpi_device object with LNXVIDEO 'bus_id' will be created for
+      it.
+
+The third column of the above table indicates which ACPI System
+Description Tables contain information used for the creation of the
+struct acpi_device objects represented by the given row (xSDT means DSDT
+or SSDT).
+
+The forth column of the above table indicates the 'bus_id' generation
+rule of the struct acpi_device object:
+
+   _HID:
+      _HID in the last column of the table means that the object's bus_id
+      is derived from the _HID/_CID identification objects present under
+      the corresponding ACPI namespace node. The object's sysfs directory
+      will then contain the 'hid' and 'modalias' attributes that can be
+      used to retrieve the _HID and _CIDs of that object.
+   LNXxxxxx:
+      The 'modalias' attribute is also present for struct acpi_device
+      objects having bus_id of the "LNXxxxxx" form (pseudo devices), in
+      which cases it contains the bus_id string itself.
+   device:
+      'device' in the last column of the table indicates that the object's
+      bus_id cannot be determined from _HID/_CID of the corresponding
+      ACPI namespace node, although that object represents a device (for
+      example, it may be a PCI device with _ADR defined and without _HID
+      or _CID).  In that case the string 'device' will be used as the
+      object's bus_id.
+
+
+Linux ACPI Physical Device Glue
+===============================
+
+ACPI device (i.e. struct acpi_device) objects may be linked to other
+objects in the Linux' device hierarchy that represent "physical" devices
+(for example, devices on the PCI bus).  If that happens, it means that
+the ACPI device object is a "companion" of a device otherwise
+represented in a different way and is used (1) to provide configuration
+information on that device which cannot be obtained by other means and
+(2) to do specific things to the device with the help of its ACPI
+control methods.  One ACPI device object may be linked this way to
+multiple "physical" devices.
+
+If an ACPI device object is linked to a "physical" device, its sysfs
+directory contains the "physical_node" symbolic link to the sysfs
+directory of the target device object.  In turn, the target device's
+sysfs directory will then contain the "firmware_node" symbolic link to
+the sysfs directory of the companion ACPI device object.
+The linking mechanism relies on device identification provided by the
+ACPI namespace.  For example, if there's an ACPI namespace object
+representing a PCI device (i.e. a device object under an ACPI namespace
+object representing a PCI bridge) whose _ADR returns 0x00020000 and the
+bus number of the parent PCI bridge is 0, the sysfs directory
+representing the struct acpi_device object created for that ACPI
+namespace object will contain the 'physical_node' symbolic link to the
+/sys/devices/pci0000:00/0000:00:02:0/ sysfs directory of the
+corresponding PCI device.
+
+The linking mechanism is generally bus-specific.  The core of its
+implementation is located in the drivers/acpi/glue.c file, but there are
+complementary parts depending on the bus types in question located
+elsewhere.  For example, the PCI-specific part of it is located in
+drivers/pci/pci-acpi.c.

+==========================
+ACPI _OSI and _REV methods
+==========================
+
+An ACPI BIOS can use the "Operating System Interfaces" method (_OSI)
+to find out what the operating system supports. Eg. If BIOS
+AML code includes _OSI("XYZ"), the kernel's AML interpreter
+can evaluate that method, look to see if it supports 'XYZ'
+and answer YES or NO to the BIOS.
+
+The ACPI _REV method returns the "Revision of the ACPI specification
+that OSPM supports"
+
+This document explains how and why the BIOS and Linux should use these methods.
+It also explains how and why they are widely misused.
+
+How to use _OSI
+===============
+
+Linux runs on two groups of machines -- those that are tested by the OEM
+to be compatible with Linux, and those that were never tested with Linux,
+but where Linux was installed to replace the original OS (Windows or OSX).
+
+The larger group is the systems tested to run only Windows.  Not only that,
+but many were tested to run with just one specific version of Windows.
+So even though the BIOS may use _OSI to query what version of Windows is running,
+only a single path through the BIOS has actually been tested.
+Experience shows that taking untested paths through the BIOS
+exposes Linux to an entire category of BIOS bugs.
+For this reason, Linux _OSI defaults must continue to claim compatibility
+with all versions of Windows.
+
+But Linux isn't actually compatible with Windows, and the Linux community
+has also been hurt with regressions when Linux adds the latest version of
+Windows to its list of _OSI strings.  So it is possible that additional strings
+will be more thoroughly vetted before shipping upstream in the future.
+But it is likely that they will all eventually be added.
+
+What should an OEM do if they want to support Linux and Windows
+using the same BIOS image?  Often they need to do something different
+for Linux to deal with how Linux is different from Windows.
+Here the BIOS should ask exactly what it wants to know:
+
+_OSI("Linux-OEM-my_interface_name")
+where 'OEM' is needed if this is an OEM-specific hook,
+and 'my_interface_name' describes the hook, which could be a
+quirk, a bug, or a bug-fix.
+
+In addition, the OEM should send a patch to upstream Linux
+via the linux-acpi@vger.kernel.org mailing list.  When that patch
+is checked into Linux, the OS will answer "YES" when the BIOS
+on the OEM's system uses _OSI to ask if the interface is supported
+by the OS.  Linux distributors can back-port that patch for Linux
+pre-installs, and it will be included by all distributions that
+re-base to upstream.  If the distribution can not update the kernel binary,
+they can also add an acpi_osi=Linux-OEM-my_interface_name
+cmdline parameter to the boot loader, as needed.
+
+If the string refers to a feature where the upstream kernel
+eventually grows support, a patch should be sent to remove
+the string when that support is added to the kernel.
+
+That was easy.  Read on, to find out how to do it wrong.
+
+Before _OSI, there was _OS
+==========================
+
+ACPI 1.0 specified "_OS" as an
+"object that evaluates to a string that identifies the operating system."
+
+The ACPI BIOS flow would include an evaluation of _OS, and the AML
+interpreter in the kernel would return to it a string identifying the OS:
+
+Windows 98, SE: "Microsoft Windows"
+Windows ME: "Microsoft WindowsME:Millenium Edition"
+Windows NT: "Microsoft Windows NT"
+
+The idea was on a platform tasked with running multiple OS's,
+the BIOS could use _OS to enable devices that an OS
+might support, or enable quirks or bug workarounds
+necessary to make the platform compatible with that pre-existing OS.
+
+But _OS had fundamental problems.  First, the BIOS needed to know the name
+of every possible version of the OS that would run on it, and needed to know
+all the quirks of those OS's.  Certainly it would make more sense
+for the BIOS to ask *specific* things of the OS, such
+"do you support a specific interface", and thus in ACPI 3.0,
+_OSI was born to replace _OS.
+
+_OS was abandoned, though even today, many BIOS look for
+_OS "Microsoft Windows NT", though it seems somewhat far-fetched
+that anybody would install those old operating systems
+over what came with the machine.
+
+Linux answers "Microsoft Windows NT" to please that BIOS idiom.
+That is the *only* viable strategy, as that is what modern Windows does,
+and so doing otherwise could steer the BIOS down an untested path.
+
+_OSI is born, and immediately misused
+=====================================
+
+With _OSI, the *BIOS* provides the string describing an interface,
+and asks the OS: "YES/NO, are you compatible with this interface?"
+
+eg. _OSI("3.0 Thermal Model") would return TRUE if the OS knows how
+to deal with the thermal extensions made to the ACPI 3.0 specification.
+An old OS that doesn't know about those extensions would answer FALSE,
+and a new OS may be able to return TRUE.
+
+For an OS-specific interface, the ACPI spec said that the BIOS and the OS
+were to agree on a string of the form such as "Windows-interface_name".
+
+But two bad things happened.  First, the Windows ecosystem used _OSI
+not as designed, but as a direct replacement for _OS -- identifying
+the OS version, rather than an OS supported interface.  Indeed, right
+from the start, the ACPI 3.0 spec itself codified this misuse
+in example code using _OSI("Windows 2001").
+
+This misuse was adopted and continues today.
+
+Linux had no choice but to also return TRUE to _OSI("Windows 2001")
+and its successors.  To do otherwise would virtually guarantee breaking
+a BIOS that has been tested only with that _OSI returning TRUE.
+
+This strategy is problematic, as Linux is never completely compatible with
+the latest version of Windows, and sometimes it takes more than a year
+to iron out incompatibilities.
+
+Not to be out-done, the Linux community made things worse by returning TRUE
+to _OSI("Linux").  Doing so is even worse than the Windows misuse
+of _OSI, as "Linux" does not even contain any version information.
+_OSI("Linux") led to some BIOS' malfunctioning due to BIOS writer's
+using it in untested BIOS flows.  But some OEM's used _OSI("Linux")
+in tested flows to support real Linux features.  In 2009, Linux
+removed _OSI("Linux"), and added a cmdline parameter to restore it
+for legacy systems still needed it.  Further a BIOS_BUG warning prints
+for all BIOS's that invoke it.
+
+No BIOS should use _OSI("Linux").
+
+The result is a strategy for Linux to maximize compatibility with
+ACPI BIOS that are tested on Windows machines.  There is a real risk
+of over-stating that compatibility; but the alternative has often been
+catastrophic failure resulting from the BIOS taking paths that
+were never validated under *any* OS.
+
+Do not use _REV
+===============
+
+Since _OSI("Linux") went away, some BIOS writers used _REV
+to support Linux and Windows differences in the same BIOS.
+
+_REV was defined in ACPI 1.0 to return the version of ACPI
+supported by the OS and the OS AML interpreter.
+
+Modern Windows returns _REV = 2.  Linux used ACPI_CA_SUPPORT_LEVEL,
+which would increment, based on the version of the spec supported.
+
+Unfortunately, _REV was also misused.  eg. some BIOS would check
+for _REV = 3, and do something for Linux, but when Linux returned
+_REV = 4, that support broke.
+
+In response to this problem, Linux returns _REV = 2 always,
+from mid-2015 onward.  The ACPI specification will also be updated
+to reflect that _REV is deprecated, and always returns 2.
+
+Apple Mac and _OSI("Darwin")
+============================
+
+On Apple's Mac platforms, the ACPI BIOS invokes _OSI("Darwin")
+to determine if the machine is running Apple OSX.
+
+Like Linux's _OSI("*Windows*") strategy, Linux defaults to
+answering YES to _OSI("Darwin") to enable full access
+to the hardware and validated BIOS paths seen by OSX.
+Just like on Windows-tested platforms, this strategy has risks.
+
+Starting in Linux-3.18, the kernel answered YES to _OSI("Darwin")
+for the purpose of enabling Mac Thunderbolt support.  Further,
+if the kernel noticed _OSI("Darwin") being invoked, it additionally
+disabled all _OSI("*Windows*") to keep poorly written Mac BIOS
+from going down untested combinations of paths.
+
+The Linux-3.18 change in default caused power regressions on Mac
+laptops, and the 3.18 implementation did not allow changing
+the default via cmdline "acpi_osi=!Darwin".  Linux-4.7 fixed
+the ability to use acpi_osi=!Darwin as a workaround, and
+we hope to see Mac Thunderbolt power management support in Linux-4.11.

+=====================
+ACPI video extensions
+=====================
+
+This driver implement the ACPI Extensions For Display Adapters for
+integrated graphics devices on motherboard, as specified in ACPI 2.0
+Specification, Appendix B, allowing to perform some basic control like
+defining the video POST device, retrieving EDID information or to
+setup a video output, etc.  Note that this is an ref. implementation
+only.  It may or may not work for your integrated video device.
+
+The ACPI video driver does 3 things regarding backlight control.
+
+Export a sysfs interface for user space to control backlight level
+==================================================================
+
+If the ACPI table has a video device, and acpi_backlight=vendor kernel
+command line is not present, the driver will register a backlight device
+and set the required backlight operation structure for it for the sysfs
+interface control. For every registered class device, there will be a
+directory named acpi_videoX under /sys/class/backlight.
+
+The backlight sysfs interface has a standard definition here:
+Documentation/ABI/stable/sysfs-class-backlight.
+
+And what ACPI video driver does is:
+
+actual_brightness:
+  on read, control method _BQC will be evaluated to
+  get the brightness level the firmware thinks it is at;
+bl_power:
+  not implemented, will set the current brightness instead;
+brightness:
+  on write, control method _BCM will run to set the requested brightness level;
+max_brightness:
+  Derived from the _BCL package(see below);
+type:
+  firmware
+
+Note that ACPI video backlight driver will always use index for
+brightness, actual_brightness and max_brightness. So if we have
+the following _BCL package::
+
+	Method (_BCL, 0, NotSerialized)
+	{
+		Return (Package (0x0C)
+		{
+			0x64,
+			0x32,
+			0x0A,
+			0x14,
+			0x1E,
+			0x28,
+			0x32,
+			0x3C,
+			0x46,
+			0x50,
+			0x5A,
+			0x64
+		})
+	}
+
+The first two levels are for when laptop are on AC or on battery and are
+not used by Linux currently. The remaining 10 levels are supported levels
+that we can choose from. The applicable index values are from 0 (that
+corresponds to the 0x0A brightness value) to 9 (that corresponds to the
+0x64 brightness value) inclusive. Each of those index values is regarded
+as a "brightness level" indicator. Thus from the user space perspective
+the range of available brightness levels is from 0 to 9 (max_brightness)
+inclusive.
+
+Notify user space about hotkey event
+====================================
+
+There are generally two cases for hotkey event reporting:
+
+i) For some laptops, when user presses the hotkey, a scancode will be
+   generated and sent to user space through the input device created by
+   the keyboard driver as a key type input event, with proper remap, the
+   following key code will appear to user space::
+
+	EV_KEY, KEY_BRIGHTNESSUP
+	EV_KEY, KEY_BRIGHTNESSDOWN
+	etc.
+
+For this case, ACPI video driver does not need to do anything(actually,
+it doesn't even know this happened).
+
+ii) For some laptops, the press of the hotkey will not generate the
+    scancode, instead, firmware will notify the video device ACPI node
+    about the event. The event value is defined in the ACPI spec. ACPI
+    video driver will generate an key type input event according to the
+    notify value it received and send the event to user space through the
+    input device it created:
+
+	=====		==================
+	event		keycode
+	=====		==================
+	0x86		KEY_BRIGHTNESSUP
+	0x87		KEY_BRIGHTNESSDOWN
+	etc.
+	=====		==================
+
+so this would lead to the same effect as case i) now.
+
+Once user space tool receives this event, it can modify the backlight
+level through the sysfs interface.
+
+Change backlight level in the kernel
+====================================
+
+This works for machines covered by case ii) in Section 2. Once the driver
+received a notification, it will set the backlight level accordingly. This does
+not affect the sending of event to user space, they are always sent to user
+space regardless of whether or not the video module controls the backlight level
+directly. This behaviour can be controlled through the brightness_switch_enabled
+module parameter as documented in admin-guide/kernel-parameters.rst. It is
+recommended to disable this behaviour once a GUI environment starts up and
+wants to have full control of the backlight level.

+GPIO Sysfs Interface for Userspace
+==================================
+
+.. warning::
+
+  THIS ABI IS DEPRECATED, THE ABI DOCUMENTATION HAS BEEN MOVED TO
+  Documentation/ABI/obsolete/sysfs-gpio AND NEW USERSPACE CONSUMERS
+  ARE SUPPOSED TO USE THE CHARACTER DEVICE ABI. THIS OLD SYSFS ABI WILL
+  NOT BE DEVELOPED (NO NEW FEATURES), IT WILL JUST BE MAINTAINED.
+
+Refer to the examples in tools/gpio/* for an introduction to the new
+character device ABI. Also see the userspace header in
+include/uapi/linux/gpio.h
+
+The deprecated sysfs ABI
+------------------------
+Platforms which use the "gpiolib" implementors framework may choose to
+configure a sysfs user interface to GPIOs. This is different from the
+debugfs interface, since it provides control over GPIO direction and
+value instead of just showing a gpio state summary. Plus, it could be
+present on production systems without debugging support.
+
+Given appropriate hardware documentation for the system, userspace could
+know for example that GPIO #23 controls the write protect line used to
+protect boot loader segments in flash memory. System upgrade procedures
+may need to temporarily remove that protection, first importing a GPIO,
+then changing its output state, then updating the code before re-enabling
+the write protection. In normal use, GPIO #23 would never be touched,
+and the kernel would have no need to know about it.
+
+Again depending on appropriate hardware documentation, on some systems
+userspace GPIO can be used to determine system configuration data that
+standard kernels won't know about. And for some tasks, simple userspace
+GPIO drivers could be all that the system really needs.
+
+DO NOT ABUSE SYSFS TO CONTROL HARDWARE THAT HAS PROPER KERNEL DRIVERS.
+PLEASE READ THE DOCUMENT AT Documentation/driver-api/gpio/drivers-on-gpio.rst
+TO AVOID REINVENTING KERNEL WHEELS IN USERSPACE. I MEAN IT. REALLY.
+
+Paths in Sysfs
+--------------
+There are three kinds of entries in /sys/class/gpio:
+
+   -	Control interfaces used to get userspace control over GPIOs;
+
+   -	GPIOs themselves; and
+
+   -	GPIO controllers ("gpio_chip" instances).
+
+That's in addition to standard files including the "device" symlink.
+
+The control interfaces are write-only:
+
+    /sys/class/gpio/
+
+	"export" ...
+		Userspace may ask the kernel to export control of
+		a GPIO to userspace by writing its number to this file.
+
+		Example:  "echo 19 > export" will create a "gpio19" node
+		for GPIO #19, if that's not requested by kernel code.
+
+	"unexport" ...
+		Reverses the effect of exporting to userspace.
+
+		Example:  "echo 19 > unexport" will remove a "gpio19"
+		node exported using the "export" file.
+
+GPIO signals have paths like /sys/class/gpio/gpio42/ (for GPIO #42)
+and have the following read/write attributes:
+
+    /sys/class/gpio/gpioN/
+
+	"direction" ...
+		reads as either "in" or "out". This value may
+		normally be written. Writing as "out" defaults to
+		initializing the value as low. To ensure glitch free
+		operation, values "low" and "high" may be written to
+		configure the GPIO as an output with that initial value.
+
+		Note that this attribute *will not exist* if the kernel
+		doesn't support changing the direction of a GPIO, or
+		it was exported by kernel code that didn't explicitly
+		allow userspace to reconfigure this GPIO's direction.
+
+	"value" ...
+		reads as either 0 (low) or 1 (high). If the GPIO
+		is configured as an output, this value may be written;
+		any nonzero value is treated as high.
+
+		If the pin can be configured as interrupt-generating interrupt
+		and if it has been configured to generate interrupts (see the
+		description of "edge"), you can poll(2) on that file and
+		poll(2) will return whenever the interrupt was triggered. If
+		you use poll(2), set the events POLLPRI and POLLERR. If you
+		use select(2), set the file descriptor in exceptfds. After
+		poll(2) returns, either lseek(2) to the beginning of the sysfs
+		file and read the new value or close the file and re-open it
+		to read the value.
+
+	"edge" ...
+		reads as either "none", "rising", "falling", or
+		"both". Write these strings to select the signal edge(s)

+	"active_low" ...

+
+GPIO controllers have paths like /sys/class/gpio/gpiochip42/ (for the
+controller implementing GPIOs starting at #42) and have the following
+read-only attributes:
+
+    /sys/class/gpio/gpiochipN/
+
+	"base" ...
+		same as N, the first GPIO managed by this chip
+
+	"label" ...
+		provided for diagnostics (not always unique)
+
+	"ngpio" ...
+		how many GPIOs this manages (N to N + ngpio - 1)
+
+Board documentation should in most cases cover what GPIOs are used for
+what purposes. However, those numbers are not always stable; GPIOs on
+a daughtercard might be different depending on the base board being used,
+or other cards in the stack. In such cases, you may need to use the
+gpiochip nodes (possibly in conjunction with schematics) to determine
+the correct GPIO number to use for a given signal.
+
+
+Exporting from Kernel code
+--------------------------
+Kernel code can explicitly manage exports of GPIOs which have already been
+requested using gpio_request()::
+
+	/* export the GPIO to userspace */
+	int gpiod_export(struct gpio_desc *desc, bool direction_may_change);
+
+	/* reverse gpio_export() */
+	void gpiod_unexport(struct gpio_desc *desc);
+
+	/* create a sysfs link to an exported GPIO node */
+	int gpiod_export_link(struct device *dev, const char *name,
+		      struct gpio_desc *desc);
+
+After a kernel driver requests a GPIO, it may only be made available in
+the sysfs interface by gpiod_export(). The driver can control whether the
+signal direction may change. This helps drivers prevent userspace code
+from accidentally clobbering important system state.
+
+This explicit exporting can help with debugging (by making some kinds
+of experiments easier), or can provide an always-there interface that's
+suitable for documenting as part of a board support package.
+
+After the GPIO has been exported, gpiod_export_link() allows creating
+symlinks from elsewhere in sysfs to the GPIO sysfs node. Drivers can
+use this to provide the interface under their own device in sysfs with
+a descriptive name.

-GPIO Sysfs Interface for Userspace
-==================================
-
-THIS ABI IS DEPRECATED, THE ABI DOCUMENTATION HAS BEEN MOVED TO
-Documentation/ABI/obsolete/sysfs-gpio AND NEW USERSPACE CONSUMERS
-ARE SUPPOSED TO USE THE CHARACTER DEVICE ABI. THIS OLD SYSFS ABI WILL
-NOT BE DEVELOPED (NO NEW FEATURES), IT WILL JUST BE MAINTAINED.
-
-Refer to the examples in tools/gpio/* for an introduction to the new
-character device ABI. Also see the userspace header in
-include/uapi/linux/gpio.h
-
-The deprecated sysfs ABI
-------------------------
-Platforms which use the "gpiolib" implementors framework may choose to
-configure a sysfs user interface to GPIOs. This is different from the
-debugfs interface, since it provides control over GPIO direction and
-value instead of just showing a gpio state summary. Plus, it could be
-present on production systems without debugging support.
-
-Given appropriate hardware documentation for the system, userspace could
-know for example that GPIO #23 controls the write protect line used to
-protect boot loader segments in flash memory. System upgrade procedures
-may need to temporarily remove that protection, first importing a GPIO,
-then changing its output state, then updating the code before re-enabling
-the write protection. In normal use, GPIO #23 would never be touched,
-and the kernel would have no need to know about it.
-
-Again depending on appropriate hardware documentation, on some systems
-userspace GPIO can be used to determine system configuration data that
-standard kernels won't know about. And for some tasks, simple userspace
-GPIO drivers could be all that the system really needs.
-
-DO NOT ABUSE SYSFS TO CONTROL HARDWARE THAT HAS PROPER KERNEL DRIVERS.
-PLEASE READ THE DOCUMENT AT Documentation/driver-api/gpio/drivers-on-gpio.rst
-TO AVOID REINVENTING KERNEL WHEELS IN USERSPACE. I MEAN IT. REALLY.
-
-Paths in Sysfs
---------------
-There are three kinds of entries in /sys/class/gpio:
-
-   -	Control interfaces used to get userspace control over GPIOs;
-
-   -	GPIOs themselves; and
-
-   -	GPIO controllers ("gpio_chip" instances).
-
-That's in addition to standard files including the "device" symlink.
-
-The control interfaces are write-only:
-
-    /sys/class/gpio/
-
-    	"export" ... Userspace may ask the kernel to export control of
-		a GPIO to userspace by writing its number to this file.
-
-		Example:  "echo 19 > export" will create a "gpio19" node
-		for GPIO #19, if that's not requested by kernel code.
-
-    	"unexport" ... Reverses the effect of exporting to userspace.
-
-		Example:  "echo 19 > unexport" will remove a "gpio19"
-		node exported using the "export" file.
-
-GPIO signals have paths like /sys/class/gpio/gpio42/ (for GPIO #42)
-and have the following read/write attributes:
-
-    /sys/class/gpio/gpioN/
-
-	"direction" ... reads as either "in" or "out". This value may
-		normally be written. Writing as "out" defaults to
-		initializing the value as low. To ensure glitch free
-		operation, values "low" and "high" may be written to
-		configure the GPIO as an output with that initial value.
-
-		Note that this attribute *will not exist* if the kernel
-		doesn't support changing the direction of a GPIO, or
-		it was exported by kernel code that didn't explicitly
-		allow userspace to reconfigure this GPIO's direction.
-
-	"value" ... reads as either 0 (low) or 1 (high). If the GPIO
-		is configured as an output, this value may be written;
-		any nonzero value is treated as high.
-
-		If the pin can be configured as interrupt-generating interrupt
-		and if it has been configured to generate interrupts (see the
-		description of "edge"), you can poll(2) on that file and
-		poll(2) will return whenever the interrupt was triggered. If
-		you use poll(2), set the events POLLPRI and POLLERR. If you
-		use select(2), set the file descriptor in exceptfds. After
-		poll(2) returns, either lseek(2) to the beginning of the sysfs
-		file and read the new value or close the file and re-open it
-		to read the value.
-
-	"edge" ... reads as either "none", "rising", "falling", or
-		"both". Write these strings to select the signal edge(s)
-		that will make poll(2) on the "value" file return.
-
-		This file exists only if the pin can be configured as an
-		interrupt generating input pin.
-
-	"active_low" ... reads as either 0 (false) or 1 (true). Write
-		any nonzero value to invert the value attribute both
-		for reading and writing. Existing and subsequent
-		poll(2) support configuration via the edge attribute
-		for "rising" and "falling" edges will follow this
-		setting.
-
-GPIO controllers have paths like /sys/class/gpio/gpiochip42/ (for the
-controller implementing GPIOs starting at #42) and have the following
-read-only attributes:
-
-    /sys/class/gpio/gpiochipN/
-
-    	"base" ... same as N, the first GPIO managed by this chip
-
-    	"label" ... provided for diagnostics (not always unique)
-
-        "ngpio" ... how many GPIOs this manages (N to N + ngpio - 1)
-

-what purposes. However, those numbers are not always stable; GPIOs on

-=======================
-
-Supported chips:
-  * Abit uGuru revision 1 & 2 (Hardware Monitor part only)
-    Prefix: 'abituguru'
-    Addresses scanned: ISA 0x0E0
-    Datasheet: Not available, this driver is based on reverse engineering.
-	A "Datasheet" has been written based on the reverse engineering it
-	should be available in the same dir as this file under the name
-	abituguru-datasheet.
-    Note:
-	The uGuru is a microcontroller with onboard firmware which programs
-	it to behave as a hwmon IC. There are many different revisions of the
-	firmware and thus effectivly many different revisions of the uGuru.
-	Below is an incomplete list with which revisions are used for which
-	Motherboards:
-	uGuru 1.00    ~ 1.24    (AI7, KV8-MAX3, AN7) (1)
-	uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
-	uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
-	uGuru 2.2.0.0 ~ 2.2.0.6 (AA8 Fatal1ty)
-	uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
-	uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
-				 AW9D-MAX) (2)
-	1) For revisions 2 and 3 uGuru's the driver can autodetect the
-	   sensortype (Volt or Temp) for bank1 sensors, for revision 1 uGuru's
-	   this does not always work. For these uGuru's the autodetection can
-	   be overridden with the bank1_types module param. For all 3 known
-	   revison 1 motherboards the correct use of this param is:
-	   bank1_types=1,1,0,0,0,0,0,2,0,0,0,0,2,0,0,1
-	   You may also need to specify the fan_sensors option for these boards
-	   fan_sensors=5
-	2) There is a separate abituguru3 driver for these motherboards,
-	   the abituguru (without the 3 !) driver will not work on these
-	   motherboards (and visa versa)!

-
-Module Parameters
------------------
-
-* force: bool		Force detection. Note this parameter only causes the
-			detection to be skipped, and thus the insmod to
-			succeed. If the uGuru can't be read the actual hwmon
-			driver will not load and thus no hwmon device will get
-			registered.
-* bank1_types: int[]	Bank1 sensortype autodetection override:
-			  -1 autodetect (default)
-			   0 volt sensor
-			   1 temp sensor
-			   2 not connected
-* fan_sensors: int	Tell the driver how many fan speed sensors there are
-			on your motherboard. Default: 0 (autodetect).
-* pwms: int		Tell the driver how many fan speed controls (fan
-			pwms) your motherboard has. Default: 0 (autodetect).
-* verbose: int		How verbose should the driver be? (0-3):
-			   0 normal output
-			   1 + verbose error reporting
-			   2 + sensors type probing info (default)
-			   3 + retryable error reporting
-			Default: 2 (the driver is still in the testing phase)
-
-Notice if you need any of the first three options above please insmod the
-driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
-dmesg | grep abituguru
-
-
-Description
------------
-
-This driver supports the hardware monitoring features of the first and
-second revision of the Abit uGuru chip found on Abit uGuru featuring
-motherboards (most modern Abit motherboards).
-
-The first and second revision of the uGuru chip in reality is a Winbond
-W83L950D in disguise (despite Abit claiming it is "a new microprocessor
-designed by the ABIT Engineers"). Unfortunately this doesn't help since the
-W83L950D is a generic microcontroller with a custom Abit application running
-on it.
-
-Despite Abit not releasing any information regarding the uGuru, Olle
-Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
-of the uGuru. Without his work this driver would not have been possible.
-
-Known Issues
-------------
-
-The voltage and frequency control parts of the Abit uGuru are not supported.

-Module Parameters
------------------
-
-* force: bool		Force detection. Note this parameter only causes the
-			detection to be skipped, and thus the insmod to
-			succeed. If the uGuru can't be read the actual hwmon
-			driver will not load and thus no hwmon device will get
-			registered.
-* verbose: bool		Should the driver be verbose?
-			0/off/false  normal output
-			1/on/true    + verbose error reporting (default)
-			Default: 1 (the driver is still in the testing phase)
-
-Description
------------
-
-This driver supports the hardware monitoring features of the third revision of
-the Abit uGuru chip, found on recent Abit uGuru featuring motherboards.
-
-The 3rd revision of the uGuru chip in reality is a Winbond W83L951G.
-Unfortunately this doesn't help since the W83L951G is a generic microcontroller
-with a custom Abit application running on it.
-
-Despite Abit not releasing any information regarding the uGuru revision 3,
-Louis Kruger has managed to reverse engineer the sensor part of the uGuru.
-Without his work this driver would not have been possible.
-
-Known Issues
-------------
-
-The voltage and frequency control parts of the Abit uGuru are not supported,
-neither is writing any of the sensor settings and writing / reading the
-fanspeed control registers (FanEQ)
-
-If you encounter any problems please mail me <j.w.r.degoede@hhs.nl> and
-include the output of: "dmesg | grep abituguru"

-uGuru datasheet
-===============
-
-First of all, what I know about uGuru is no fact based on any help, hints or
-datasheet from Abit. The data I have got on uGuru have I assembled through
-my weak knowledge in "backwards engineering".
-And just for the record, you may have noticed uGuru isn't a chip developed by
-Abit, as they claim it to be. It's really just an microprocessor (uC) created by
-Winbond (W83L950D). And no, reading the manual for this specific uC or
-mailing  Windbond for help won't give any useful data about uGuru, as it is
-the program inside the uC that is responding to calls.

-Original version by Olle Sandberg who did the heavy lifting of the initial

-and extended with write support and info on more databanks, the write support
-is once again reverse engineered by Olle the additional databanks have been
-reverse engineered by me. I would like to express my thanks to Olle, this
-document and the Linux driver could not have been written without his efforts.

-
-Detection
-=========
-
-As far as known the uGuru is always placed at and using the (ISA) I/O-ports
-0xE0 and 0xE4, so we don't have to scan any port-range, just check what the two
-ports are holding for detection. We will refer to 0xE0 as CMD (command-port)
-and 0xE4 as DATA because Abit refers to them with these names.
-
-If DATA holds 0x00 or 0x08 and CMD holds 0x00 or 0xAC an uGuru could be
-present. We have to check for two different values at data-port, because
-after a reboot uGuru will hold 0x00 here, but if the driver is removed and
-later on attached again data-port will hold 0x08, more about this later.
-
-After wider testing of the Linux kernel driver some variants of the uGuru have
-turned up which will hold 0x00 instead of 0xAC at the CMD port, thus we also
-have to test CMD for two different values. On these uGuru's DATA will initially
-hold 0x09 and will only hold 0x08 after reading CMD first, so CMD must be read
-first!
-
-To be really sure an uGuru is present a test read of one or more register
-sets should be done.
-
-
-Reading / Writing
-=================
-
-Addressing
-----------
-
-The uGuru has a number of different addressing levels. The first addressing
-level we will call banks. A bank holds data for one or more sensors. The data
-in a bank for a sensor is one or more bytes large.
-
-The number of bytes is fixed for a given bank, you should always read or write
-that many bytes, reading / writing more will fail, the results when writing
-less then the number of bytes for a given bank are undetermined.
-
-See below for all known bank addresses, numbers of sensors in that bank,
-number of bytes data per sensor and contents/meaning of those bytes.
-
-Although both this document and the kernel driver have kept the sensor
-terminoligy for the addressing within a bank this is not 100% correct, in
-bank 0x24 for example the addressing within the bank selects a PWM output not
-a sensor.
-
-Notice that some banks have both a read and a write address this is how the
-uGuru determines if a read from or a write to the bank is taking place, thus
-when reading you should always use the read address and when writing the
-write address. The write address is always one (1) more than the read address.
-
-
-uGuru ready
------------
-
-Before you can read from or write to the uGuru you must first put the uGuru
-in "ready" mode.
-
-To put the uGuru in ready mode first write 0x00 to DATA and then wait for DATA
-to hold 0x09, DATA should read 0x09 within 250 read cycles.
-
-Next CMD _must_ be read and should hold 0xAC, usually CMD will hold 0xAC the
-first read but sometimes it takes a while before CMD holds 0xAC and thus it
-has to be read a number of times (max 50).
-
-After reading CMD, DATA should hold 0x08 which means that the uGuru is ready
-for input. As above DATA will usually hold 0x08 the first read but not always.
-This step can be skipped, but it is undetermined what happens if the uGuru has
-not yet reported 0x08 at DATA and you proceed with writing a bank address.
-
-
-Sending bank and sensor addresses to the uGuru
-----------------------------------------------
-
-First the uGuru must be in "ready" mode as described above, DATA should hold
-0x08 indicating that the uGuru wants input, in this case the bank address.
-
-Next write the bank address to DATA. After the bank address has been written
-wait for to DATA to hold 0x08 again indicating that it wants / is ready for
-more input (max 250 reads).
-
-Once DATA holds 0x08 again write the sensor address to CMD.
-
-
-Reading
--------
-
-First send the bank and sensor addresses as described above.
-Then for each byte of data you want to read wait for DATA to hold 0x01
-which indicates that the uGuru is ready to be read (max 250 reads) and once
-DATA holds 0x01 read the byte from CMD.
-
-Once all bytes have been read data will hold 0x09, but there is no reason to
-test for this. Notice that the number of bytes is bank address dependent see
-above and below.
-
-After completing a successful read it is advised to put the uGuru back in
-ready mode, so that it is ready for the next read / write cycle. This way
-if your program / driver is unloaded and later loaded again the detection
-algorithm described above will still work.
-
-
-
-Writing
--------
-
-First send the bank and sensor addresses as described above.
-Then for each byte of data you want to write wait for DATA to hold 0x00
-which indicates that the uGuru is ready to be written (max 250 reads) and
-once DATA holds 0x00 write the byte to CMD.
-
-Once all bytes have been written wait for DATA to hold 0x01 (max 250 reads)
-don't ask why this is the way it is.
-
-Once DATA holds 0x01 read CMD it should hold 0xAC now.
-
-After completing a successful write it is advised to put the uGuru back in
-ready mode, so that it is ready for the next read / write cycle. This way
-if your program / driver is unloaded and later loaded again the detection
-algorithm described above will still work.
-
-
-Gotchas
--------
-
-After wider testing of the Linux kernel driver some variants of the uGuru have
-turned up which do not hold 0x08 at DATA within 250 reads after writing the
-bank address. With these versions this happens quite frequent, using larger
-timeouts doesn't help, they just go offline for a second or 2, doing some
-internal callibration or whatever. Your code should be prepared to handle
-this and in case of no response in this specific case just goto sleep for a
-while and then retry.

-Address Map
-===========
-
-Bank 0x20 Alarms (R)
---------------------
-This bank contains 0 sensors, iow the sensor address is ignored (but must be
-written) just use 0. Bank 0x20 contains 3 bytes:
-
-Byte 0:
-This byte holds the alarm flags for sensor 0-7 of Sensor Bank1, with bit 0
-corresponding to sensor 0, 1 to 1, etc.
-
-Byte 1:
-This byte holds the alarm flags for sensor 8-15 of Sensor Bank1, with bit 0
-corresponding to sensor 8, 1 to 9, etc.
-
-Byte 2:
-This byte holds the alarm flags for sensor 0-5 of Sensor Bank2, with bit 0
-corresponding to sensor 0, 1 to 1, etc.
-
-
-Bank 0x21 Sensor Bank1 Values / Readings (R)
---------------------------------------------
-This bank contains 16 sensors, for each sensor it contains 1 byte.
-So far the following sensors are known to be available on all motherboards:
-Sensor  0 CPU temp
-Sensor  1 SYS temp
-Sensor  3 CPU core volt
-Sensor  4 DDR volt
-Sensor 10 DDR Vtt volt
-Sensor 15 PWM temp
-
-Byte 0:
-This byte holds the reading from the sensor. Sensors in Bank1 can be both
-volt and temp sensors, this is motherboard specific. The uGuru however does
-seem to know (be programmed with) what kindoff sensor is attached see Sensor
-Bank1 Settings description.
-
-Volt sensors use a linear scale, a reading 0 corresponds with 0 volt and a
-reading of 255 with 3494 mV. The sensors for higher voltages however are
-connected through a division circuit. The currently known division circuits
-in use result in ranges of: 0-4361mV, 0-6248mV or 0-14510mV. 3.3 volt sources
-use the 0-4361mV range, 5 volt the 0-6248mV and 12 volt the 0-14510mV .
-
-Temp sensors also use a linear scale, a reading of 0 corresponds with 0 degree
-Celsius and a reading of 255 with a reading of 255 degrees Celsius.
-
-
-Bank 0x22 Sensor Bank1 Settings (R)
-Bank 0x23 Sensor Bank1 Settings (W)
------------------------------------
-
-This bank contains 16 sensors, for each sensor it contains 3 bytes. Each
-set of 3 bytes contains the settings for the sensor with the same sensor
-address in Bank 0x21 .
-
-Byte 0:
-Alarm behaviour for the selected sensor. A 1 enables the described behaviour.
-Bit 0: Give an alarm if measured temp is over the warning threshold	(RW) *

-Bit 7: Volt sensor: Shutdown if alarm persist for more than 4 seconds	(RW)
-       Temp sensor: Shutdown if temp is over the shutdown threshold	(RW)
-
-*  This bit is only honored/used by the uGuru if a temp sensor is connected
-** This bit is only honored/used by the uGuru if a volt sensor is connected
-Note with some trickery this can be used to find out what kinda sensor is
-detected see the Linux kernel driver for an example with many comments on
-how todo this.
-
-Byte 1:
-Temp sensor: warning threshold  (scale as bank 0x21)
-Volt sensor: min threshold      (scale as bank 0x21)
-

-
-This bank contains 3 "sensors", for each sensor it contains 5 bytes.
-Sensor 0 usually controls the CPU fan
-Sensor 1 usually controls the NB (or chipset for single chip) fan
-Sensor 2 usually controls the System fan
-
-Byte 0:
-Flag 0x80 to enable control, Fan runs at 100% when disabled.
-low nibble (temp)sensor address at bank 0x21 used for control.
-
-Byte 1:
-0-255 = 0-12v (linear), specify voltage at which fan will rotate when under
-low threshold temp (specified in byte 3)
-
-Byte 2:
-0-255 = 0-12v (linear), specify voltage at which fan will rotate when above
-high threshold temp (specified in byte 4)
-
-Byte 3:
-Low threshold temp  (scale as bank 0x21)
-
-byte 4:
-High threshold temp (scale as bank 0x21)
-
-
-Bank 0x26 Sensors Bank2 Values / Readings (R)
----------------------------------------------
-
-This bank contains 6 sensors (AFAIK), for each sensor it contains 1 byte.
-So far the following sensors are known to be available on all motherboards:
-Sensor 0: CPU fan speed
-Sensor 1: NB (or chipset for single chip) fan speed
-Sensor 2: SYS fan speed
-
-Byte 0:
-This byte holds the reading from the sensor. 0-255 = 0-15300 (linear)
-
-
-Bank 0x27 Sensors Bank2 Settings (R)

-------------------------------------
-
-This bank contains 6 sensors (AFAIK), for each sensor it contains 2 bytes.
-

-
-Byte 1:
-min threshold (scale as bank 0x26)
-
-
-Warning for the adventurous
-===========================
-
-A word of caution to those who want to experiment and see if they can figure
-the voltage / clock programming out, I tried reading and only reading banks
-0-0x30 with the reading code used for the sensor banks (0x20-0x28) and this
-resulted in a _permanent_ reprogramming of the voltages, luckily I had the
-sensors part configured so that it would shutdown my system on any out of spec
-voltages which proprably safed my computer (after a reboot I managed to
-immediately enter the bios and reload the defaults). This probably means that
-the read/write cycle for the non sensor part is different from the sensor part.

+if your program / driver is unloaded and later loaded again the detection
+algorithm described above will still work.
+
+
+
+Writing
+-------
+
+First send the bank and sensor addresses as described above.
+Then for each byte of data you want to write wait for DATA to hold 0x00
+which indicates that the uGuru is ready to be written (max 250 reads) and
+once DATA holds 0x00 write the byte to CMD.
+
+Once all bytes have been written wait for DATA to hold 0x01 (max 250 reads)
+don't ask why this is the way it is.
+
+Once DATA holds 0x01 read CMD it should hold 0xAC now.
+
+After completing a successful write it is advised to put the uGuru back in
+ready mode, so that it is ready for the next read / write cycle. This way
+if your program / driver is unloaded and later loaded again the detection
+algorithm described above will still work.
+
+
+Gotchas
+-------
+
+After wider testing of the Linux kernel driver some variants of the uGuru have
+turned up which do not hold 0x08 at DATA within 250 reads after writing the
+bank address. With these versions this happens quite frequent, using larger
+timeouts doesn't help, they just go offline for a second or 2, doing some
+internal callibration or whatever. Your code should be prepared to handle
+this and in case of no response in this specific case just goto sleep for a
+while and then retry.

+
+Address Map
+===========
+
+Bank 0x20 Alarms (R)
+--------------------
+This bank contains 0 sensors, iow the sensor address is ignored (but must be
+written) just use 0. Bank 0x20 contains 3 bytes:
+
+Byte 0:
+  This byte holds the alarm flags for sensor 0-7 of Sensor Bank1, with bit 0
+  corresponding to sensor 0, 1 to 1, etc.
+
+Byte 1:
+  This byte holds the alarm flags for sensor 8-15 of Sensor Bank1, with bit 0
+  corresponding to sensor 8, 1 to 9, etc.
+
+Byte 2:
+  This byte holds the alarm flags for sensor 0-5 of Sensor Bank2, with bit 0
+  corresponding to sensor 0, 1 to 1, etc.
+
+
+Bank 0x21 Sensor Bank1 Values / Readings (R)
+--------------------------------------------
+This bank contains 16 sensors, for each sensor it contains 1 byte.
+So far the following sensors are known to be available on all motherboards:
+
+- Sensor  0 CPU temp
+- Sensor  1 SYS temp
+- Sensor  3 CPU core volt
+- Sensor  4 DDR volt
+- Sensor 10 DDR Vtt volt
+- Sensor 15 PWM temp
+
+Byte 0:
+  This byte holds the reading from the sensor. Sensors in Bank1 can be both
+  volt and temp sensors, this is motherboard specific. The uGuru however does
+  seem to know (be programmed with) what kindoff sensor is attached see Sensor
+  Bank1 Settings description.
+
+Volt sensors use a linear scale, a reading 0 corresponds with 0 volt and a
+reading of 255 with 3494 mV. The sensors for higher voltages however are
+connected through a division circuit. The currently known division circuits
+in use result in ranges of: 0-4361mV, 0-6248mV or 0-14510mV. 3.3 volt sources
+use the 0-4361mV range, 5 volt the 0-6248mV and 12 volt the 0-14510mV .
+
+Temp sensors also use a linear scale, a reading of 0 corresponds with 0 degree
+Celsius and a reading of 255 with a reading of 255 degrees Celsius.
+
+
+Bank 0x22 Sensor Bank1 Settings (R) and Bank 0x23 Sensor Bank1 Settings (W)
+---------------------------------------------------------------------------
+
+Those banks contain 16 sensors, for each sensor it contains 3 bytes. Each
+set of 3 bytes contains the settings for the sensor with the same sensor
+address in Bank 0x21 .
+
+Byte 0:
+  Alarm behaviour for the selected sensor. A 1 enables the described
+  behaviour.
+
+Bit 0:
+  Give an alarm if measured temp is over the warning threshold		(RW) [1]_
+
+Bit 1:
+  Give an alarm if measured volt is over the max threshold		(RW) [2]_
+
+Bit 2:
+  Give an alarm if measured volt is under the min threshold		(RW) [2]_
+
+Bit 3:
+  Beep if alarm								(RW)
+
+Bit 4:
+  1 if alarm cause measured temp is over the warning threshold		(R)
+
+Bit 5:
+  1 if alarm cause measured volt is over the max threshold		(R)
+
+Bit 6:
+  1 if alarm cause measured volt is under the min threshold		(R)
+
+Bit 7:
+  - Volt sensor: Shutdown if alarm persist for more than 4 seconds	(RW)
+  - Temp sensor: Shutdown if temp is over the shutdown threshold	(RW)
+
+.. [1] This bit is only honored/used by the uGuru if a temp sensor is connected
+
+.. [2] This bit is only honored/used by the uGuru if a volt sensor is connected
+       Note with some trickery this can be used to find out what kinda sensor
+       is detected see the Linux kernel driver for an example with many
+       comments on how todo this.
+
+Byte 1:
+  - Temp sensor: warning threshold  (scale as bank 0x21)
+  - Volt sensor: min threshold      (scale as bank 0x21)
+
+Byte 2:
+  - Temp sensor: shutdown threshold (scale as bank 0x21)
+  - Volt sensor: max threshold      (scale as bank 0x21)
+
+
+Bank 0x24 PWM outputs for FAN's (R) and Bank 0x25 PWM outputs for FAN's (W)
+---------------------------------------------------------------------------
+
+Those banks contain 3 "sensors", for each sensor it contains 5 bytes.
+  - Sensor 0 usually controls the CPU fan
+  - Sensor 1 usually controls the NB (or chipset for single chip) fan
+  - Sensor 2 usually controls the System fan
+
+Byte 0:
+  Flag 0x80 to enable control, Fan runs at 100% when disabled.
+  low nibble (temp)sensor address at bank 0x21 used for control.
+
+Byte 1:
+  0-255 = 0-12v (linear), specify voltage at which fan will rotate when under
+  low threshold temp (specified in byte 3)
+
+Byte 2:
+  0-255 = 0-12v (linear), specify voltage at which fan will rotate when above
+  high threshold temp (specified in byte 4)
+
+Byte 3:
+  Low threshold temp  (scale as bank 0x21)
+
+byte 4:
+  High threshold temp (scale as bank 0x21)
+
+
+Bank 0x26 Sensors Bank2 Values / Readings (R)
+---------------------------------------------
+
+This bank contains 6 sensors (AFAIK), for each sensor it contains 1 byte.
+
+So far the following sensors are known to be available on all motherboards:
+  - Sensor 0: CPU fan speed
+  - Sensor 1: NB (or chipset for single chip) fan speed
+  - Sensor 2: SYS fan speed
+
+Byte 0:
+  This byte holds the reading from the sensor. 0-255 = 0-15300 (linear)
+
+
+Bank 0x27 Sensors Bank2 Settings (R) and Bank 0x28 Sensors Bank2 Settings (W)
+-----------------------------------------------------------------------------
+
+Those banks contain 6 sensors (AFAIK), for each sensor it contains 2 bytes.
+
+Byte 0:
+  Alarm behaviour for the selected sensor. A 1 enables the described behaviour.
+
+Bit 0:
+  Give an alarm if measured rpm is under the min threshold	(RW)
+
+Bit 3:
+  Beep if alarm							(RW)
+
+Bit 7:
+  Shutdown if alarm persist for more than 4 seconds		(RW)
+
+Byte 1:
+  min threshold (scale as bank 0x26)
+
+
+Warning for the adventurous
+===========================
+
+A word of caution to those who want to experiment and see if they can figure
+the voltage / clock programming out, I tried reading and only reading banks
+0-0x30 with the reading code used for the sensor banks (0x20-0x28) and this
+resulted in a _permanent_ reprogramming of the voltages, luckily I had the
+sensors part configured so that it would shutdown my system on any out of spec
+voltages which proprably safed my computer (after a reboot I managed to
+immediately enter the bios and reload the defaults). This probably means that
+the read/write cycle for the non sensor part is different from the sensor part.

+Kernel driver abituguru
+=======================
+
+Supported chips:
+
+  * Abit uGuru revision 1 & 2 (Hardware Monitor part only)
+
+    Prefix: 'abituguru'
+
+    Addresses scanned: ISA 0x0E0
+
+    Datasheet: Not available, this driver is based on reverse engineering.
+    A "Datasheet" has been written based on the reverse engineering it
+    should be available in the same dir as this file under the name
+    abituguru-datasheet.
+
+    Note:
+	The uGuru is a microcontroller with onboard firmware which programs
+	it to behave as a hwmon IC. There are many different revisions of the
+	firmware and thus effectivly many different revisions of the uGuru.
+	Below is an incomplete list with which revisions are used for which
+	Motherboards:
+
+	- uGuru 1.00    ~ 1.24    (AI7, KV8-MAX3, AN7) [1]_
+	- uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
+	- uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
+	- uGuru 2.2.0.0 ~ 2.2.0.6 (AA8 Fatal1ty)
+	- uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
+	- uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
+	  AW9D-MAX) [2]_
+
+.. [1]  For revisions 2 and 3 uGuru's the driver can autodetect the
+	sensortype (Volt or Temp) for bank1 sensors, for revision 1 uGuru's
+	this does not always work. For these uGuru's the autodetection can
+	be overridden with the bank1_types module param. For all 3 known
+	revison 1 motherboards the correct use of this param is:
+	bank1_types=1,1,0,0,0,0,0,2,0,0,0,0,2,0,0,1
+	You may also need to specify the fan_sensors option for these boards
+	fan_sensors=5
+
+.. [2]  There is a separate abituguru3 driver for these motherboards,
+	the abituguru (without the 3 !) driver will not work on these
+	motherboards (and visa versa)!

+
+
+Module Parameters
+-----------------
+
+* force: bool
+			Force detection. Note this parameter only causes the
+			detection to be skipped, and thus the insmod to
+			succeed. If the uGuru can't be read the actual hwmon
+			driver will not load and thus no hwmon device will get
+			registered.
+* bank1_types: int[]
+			Bank1 sensortype autodetection override:
+
+			  * -1 autodetect (default)
+			  *  0 volt sensor
+			  *  1 temp sensor
+			  *  2 not connected
+* fan_sensors: int
+			Tell the driver how many fan speed sensors there are
+			on your motherboard. Default: 0 (autodetect).
+* pwms: int
+			Tell the driver how many fan speed controls (fan
+			pwms) your motherboard has. Default: 0 (autodetect).
+* verbose: int
+			How verbose should the driver be? (0-3):
+
+			   * 0 normal output
+			   * 1 + verbose error reporting
+			   * 2 + sensors type probing info (default)
+			   * 3 + retryable error reporting
+
+			Default: 2 (the driver is still in the testing phase)
+
+Notice: if you need any of the first three options above please insmod the
+driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
+dmesg | grep abituguru
+
+
+Description
+-----------
+
+This driver supports the hardware monitoring features of the first and
+second revision of the Abit uGuru chip found on Abit uGuru featuring
+motherboards (most modern Abit motherboards).
+
+The first and second revision of the uGuru chip in reality is a Winbond
+W83L950D in disguise (despite Abit claiming it is "a new microprocessor
+designed by the ABIT Engineers"). Unfortunately this doesn't help since the
+W83L950D is a generic microcontroller with a custom Abit application running
+on it.
+
+Despite Abit not releasing any information regarding the uGuru, Olle
+Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
+of the uGuru. Without his work this driver would not have been possible.
+
+Known Issues
+------------
+
+The voltage and frequency control parts of the Abit uGuru are not supported.

-Kernel driver power_meter
-=========================
-
-This driver talks to ACPI 4.0 power meters.
-
-Supported systems:
-  * Any recent system with ACPI 4.0.
-    Prefix: 'power_meter'
-    Datasheet: http://acpi.info/, section 10.4.
-
-Author: Darrick J. Wong
-
-Description
------------
-
-This driver implements sensor reading support for the power meters exposed in
-the ACPI 4.0 spec (Chapter 10.4).  These devices have a simple set of
-features--a power meter that returns average power use over a configurable
-interval, an optional capping mechanism, and a couple of trip points.  The
-sysfs interface conforms with the specification outlined in the "Power" section
-of Documentation/hwmon/sysfs-interface.
-
-Special Features
-----------------
-
-The power[1-*]_is_battery knob indicates if the power supply is a battery.
-Both power[1-*]_average_{min,max} must be set before the trip points will work.
-When both of them are set, an ACPI event will be broadcast on the ACPI netlink
-socket and a poll notification will be sent to the appropriate
-power[1-*]_average sysfs file.
-
-The power[1-*]_{model_number, serial_number, oem_info} fields display arbitrary
-strings that ACPI provides with the meter.  The measures/ directory contains
-symlinks to the devices that this meter measures.
-
-Some computers have the ability to enforce a power cap in hardware.  If this is
-the case, the power[1-*]_cap and related sysfs files will appear.  When the
-average power consumption exceeds the cap, an ACPI event will be broadcast on
-the netlink event socket and a poll notification will be sent to the
-appropriate power[1-*]_alarm file to indicate that capping has begun, and the
-hardware has taken action to reduce power consumption.  Most likely this will
-result in reduced performance.
-
-There are a few other ACPI notifications that can be sent by the firmware.  In
-all cases the ACPI event will be broadcast on the ACPI netlink event socket as
-well as sent as a poll notification to a sysfs file.  The events are as
-follows:
-
-power[1-*]_cap will be notified if the firmware changes the power cap.
-power[1-*]_interval will be notified if the firmware changes the averaging
-interval.

-Kernel driver adc128d818

-Description
------------
-
-This driver implements support for the Texas Instruments ADC128D818.
-It is described as 'ADC System Monitor with Temperature Sensor'.
-
-The ADC128D818 implements one temperature sensor and seven voltage sensors.
-
-Temperatures are measured in degrees Celsius. There is one set of limits.
-When the HOT Temperature Limit is crossed, this will cause an alarm that will
-be reasserted until the temperature drops below the HOT Hysteresis.
-Measurements are guaranteed between -55 and +125 degrees. The temperature
-measurement has a resolution of 0.5 degrees; the limits have a resolution
-of 1 degree.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 2.55 volts, with a resolution
-of 0.625 mV.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared by the time the alarm is read. The driver
-caches the alarm status for each sensor until it is at least reported
-once, to ensure that alarms are reported to user space.
-
-The ADC128D818 only updates its values approximately once per second;
-reading it more often will do no harm, but will return 'old' values.
-
-In addition to the scanned address list, the chip can also be configured for
-addresses 0x35 to 0x37. Those addresses are not scanned. You have to instantiate
-the driver explicitly if the chip is configured for any of those addresses in
-your system.

-Module Parameters
------------------
-
-* read_only: int
-  Don't set any values, read only mode
-
-
-Description
------------
-
-The chips supported by this driver are very similar. The Maxim MAX1617 is
-the oldest; it has the problem that it is not very well detectable. The
-MAX1617A solves that. The ADM1021 is a straight clone of the MAX1617A.
-Ditto for the THMC10. From here on, we will refer to all these chips as
-ADM1021-clones.
-
-The ADM1021 and MAX1617A reports a die code, which is a sort of revision
-code. This can help us pinpoint problems; it is not very useful
-otherwise.
-
-ADM1021-clones implement two temperature sensors. One of them is internal,
-and measures the temperature of the chip itself; the other is external and
-is realised in the form of a transistor-like device. A special alarm
-indicates whether the remote sensor is connected.
-
-Each sensor has its own low and high limits. When they are crossed, the
-corresponding alarm is set and remains on as long as the temperature stays
-out of range. Temperatures are measured in degrees Celsius. Measurements
-are possible between -65 and +127 degrees, with a resolution of one degree.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared!
-
-This driver only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values. It is possible to make
-ADM1021-clones do faster measurements, but there is really no good reason
-for that.
-
-
-Netburst-based Xeon support
----------------------------
-
-Some Xeon processors based on the Netburst (early Pentium 4, from 2001 to
-2003) microarchitecture had real MAX1617, ADM1021, or compatible chips
-within them, with two temperature sensors. Other Xeon processors of this
-era (with 400 MHz FSB) had chips with only one temperature sensor.
-
-If you have such an old Xeon, and you get two valid temperatures when
-loading the adm1021 module, then things are good.
-
-If nothing happens when loading the adm1021 module, and you are certain
-that your specific Xeon processor model includes compatible sensors, you
-will have to explicitly instantiate the sensor chips from user-space. See
-method 4 in Documentation/i2c/instantiating-devices. Possible slave
-addresses are 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e. It is likely that
-only temp2 will be correct and temp1 will have to be ignored.
-
-Previous generations of the Xeon processor (based on Pentium II/III)
-didn't have these sensors. Next generations of Xeon processors (533 MHz
-FSB and faster) lost them, until the Core-based generation which
-introduced integrated digital thermal sensors. These are supported by
-the coretemp driver.

-Description
------------
-
-(This is from Analog Devices.) The ADM1025 is a complete system hardware
-monitor for microprocessor-based systems, providing measurement and limit
-comparison of various system parameters. Five voltage measurement inputs
-are provided, for monitoring +2.5V, +3.3V, +5V and +12V power supplies and
-the processor core voltage. The ADM1025 can monitor a sixth power-supply
-voltage by measuring its own VCC. One input (two pins) is dedicated to a
-remote temperature-sensing diode and an on-chip temperature sensor allows
-ambient temperature to be monitored.
-
-One specificity of this chip is that the pin 11 can be hardwired in two
-different manners. It can act as the +12V power-supply voltage analog
-input, or as the a fifth digital entry for the VID reading (bit 4). It's
-kind of strange since both are useful, and the reason for designing the
-chip that way is obscure at least to me. The bit 5 of the configuration
-register can be used to define how the chip is hardwired. Please note that
-it is not a choice you have to make as the user. The choice was already
-made by your motherboard's maker. If the configuration bit isn't set
-properly, you'll have a wrong +12V reading or a wrong VID reading. The way
-the driver handles that is to preserve this bit through the initialization
-process, assuming that the BIOS set it up properly beforehand. If it turns
-out not to be true in some cases, we'll provide a module parameter to force
-modes.
-
-This driver also supports the ADM1025A, which differs from the ADM1025
-only in that it has "open-drain VID inputs while the ADM1025 has on-chip
-100k pull-ups on the VID inputs". It doesn't make any difference for us.

-Description
------------
-
-This driver implements support for the Analog Devices ADM1026. Analog
-Devices calls it a "complete thermal system management controller."
-
-The ADM1026 implements three (3) temperature sensors, 17 voltage sensors,
-16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
-an analog output and a PWM output along with limit, alarm and mask bits for
-all of the above. There is even 8k bytes of EEPROM memory on chip.
-
-Temperatures are measured in degrees Celsius. There are two external
-sensor inputs and one internal sensor. Each sensor has a high and low
-limit. If the limit is exceeded, an interrupt (#SMBALERT) can be
-generated. The interrupts can be masked. In addition, there are over-temp
-limits for each sensor. If this limit is exceeded, the #THERM output will
-be asserted. The current temperature and limits have a resolution of 1
-degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute) but measured
-in counts of a 22.5kHz internal clock. Each fan has a high limit which
-corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
-can be generated. Each fan can be programmed to divide the reference clock
-by 1, 2, 4 or 8. Not all RPM values can accurately be represented, so some
-rounding is done. With a divider of 8, the slowest measurable speed of a
-two pulse per revolution fan is 661 RPM.
-
-There are 17 voltage sensors. An alarm is triggered if the voltage has
-crossed a programmable minimum or maximum limit. Note that minimum in this
-case always means 'closest to zero'; this is important for negative voltage
-measurements. Several inputs have integrated attenuators so they can measure
-higher voltages directly. 3.3V, 5V, 12V, -12V and battery voltage all have
-dedicated inputs. There are several inputs scaled to 0-3V full-scale range
-for SCSI terminator power. The remaining inputs are not scaled and have
-a 0-2.5V full-scale range. A 2.5V or 1.82V reference voltage is provided
-for negative voltage measurements.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 2.0
-seconds since the last update). This means that you can easily miss
-once-only alarms.
-
-The ADM1026 measures continuously. Analog inputs are measured about 4
-times a second. Fan speed measurement time depends on fan speed and
-divisor. It can take as long as 1.5 seconds to measure all fan speeds.
-
-The ADM1026 has the ability to automatically control fan speed based on the
-temperature sensor inputs. Both the PWM output and the DAC output can be
-used to control fan speed. Usually only one of these two outputs will be
-used. Write the minimum PWM or DAC value to the appropriate control
-register. Then set the low temperature limit in the tmin values for each
-temperature sensor. The range of control is fixed at 20 °C, and the
-largest difference between current and tmin of the temperature sensors sets
-the control output. See the datasheet for several example circuits for
-controlling fan speed with the PWM and DAC outputs. The fan speed sensors
-do not have PWM compensation, so it is probably best to control the fan
-voltage from the power lead rather than on the ground lead.
-
-The datasheet shows an example application with VID signals attached to
-GPIO lines. Unfortunately, the chip may not be connected to the VID lines
-in this way. The driver assumes that the chips *is* connected this way to
-get a VID voltage.

-
-ADM1075, ADM1272, ADM1275, ADM1276, ADM1278, ADM1293, and ADM1294 are hot-swap
-controllers that allow a circuit board to be removed from or inserted into
-a live backplane. They also feature current and voltage readback via an
-integrated 12 bit analog-to-digital converter (ADC), accessed using a
-PMBus interface.
-
-The driver is a client driver to the core PMBus driver. Please see
-Documentation/hwmon/pmbus for details on PMBus client drivers.
-
-
-Usage Notes
------------
-
-This driver does not auto-detect devices. You will have to instantiate the
-devices explicitly. Please see Documentation/i2c/instantiating-devices for
-details.
-
-The ADM1075, unlike many other PMBus devices, does not support internal voltage
-or current scaling. Reported voltages, currents, and power are raw measurements,
-and will typically have to be scaled.
-
-The shunt value in micro-ohms can be set via device tree at compile-time. Please
-refer to the Documentation/devicetree/bindings/hwmon/adm1275.txt for bindings
-if the device tree is used.

-Interface
----------
-The I2C addresses listed above assume BIOS has not changed the
-chip MSB 5-bit address. Each chip reports a unique manufacturer
-identification code as well as the chip revision/stepping level.
-
-Description
------------
-[From ADM9240] The ADM9240 is a complete system hardware monitor for
-microprocessor-based systems, providing measurement and limit comparison
-of up to four power supplies and two processor core voltages, plus
-temperature, two fan speeds and chassis intrusion. Measured values can
-be read out via an I2C-compatible serial System Management Bus, and values
-for limit comparisons can be programmed in over the same serial bus. The
-high speed successive approximation ADC allows frequent sampling of all
-analog channels to ensure a fast interrupt response to any out-of-limit
-measurement.
-
-The ADM9240, DS1780 and LM81 are register compatible, the following
-details are common to the three chips. Chip differences are described
-after this section.
-
-
-Measurements
-------------
-The measurement cycle
-
-The adm9240 driver will take a measurement reading no faster than once
-each two seconds. User-space may read sysfs interface faster than the
-measurement update rate and will receive cached data from the most
-recent measurement.
-
-ADM9240 has a very fast 320us temperature and voltage measurement cycle
-with independent fan speed measurement cycles counting alternating rising
-edges of the fan tacho inputs.
-
-DS1780 measurement cycle is about once per second including fan speed.
-
-LM81 measurement cycle is about once per 400ms including fan speed.
-The LM81 12-bit extended temperature measurement mode is not supported.
-
-Temperature
------------
-On chip temperature is reported as degrees Celsius as 9-bit signed data
-with resolution of 0.5 degrees Celsius. High and low temperature limits
-are 8-bit signed data with resolution of one degree Celsius.
-
-Temperature alarm is asserted once the temperature exceeds the high limit,
-and is cleared when the temperature falls below the temp1_max_hyst value.
-
-Fan Speed
----------
-Two fan tacho inputs are provided, the ADM9240 gates an internal 22.5kHz
-clock via a divider to an 8-bit counter. Fan speed (rpm) is calculated by:
-
-rpm = (22500 * 60) / (count * divider)
-
-Automatic fan clock divider
-
-  * User sets 0 to fan_min limit
-    - low speed alarm is disabled
-    - fan clock divider not changed
-    - auto fan clock adjuster enabled for valid fan speed reading
-
-  * User sets fan_min limit too low
-    - low speed alarm is enabled
-    - fan clock divider set to max
-    - fan_min set to register value 254 which corresponds
-      to 664 rpm on adm9240
-    - low speed alarm will be asserted if fan speed is
-      less than minimum measurable speed
-    - auto fan clock adjuster disabled
-
-  * User sets reasonable fan speed
-    - low speed alarm is enabled
-    - fan clock divider set to suit fan_min
-    - auto fan clock adjuster enabled: adjusts fan_min
-
-  * User sets unreasonably high low fan speed limit
-    - resolution of the low speed limit may be reduced
-    - alarm will be asserted
-    - auto fan clock adjuster enabled: adjusts fan_min
-
-    * fan speed may be displayed as zero until the auto fan clock divider
-      adjuster brings fan speed clock divider back into chip measurement
-      range, this will occur within a few measurement cycles.
-
-Analog Output
--------------
-An analog output provides a 0 to 1.25 volt signal intended for an external
-fan speed amplifier circuit. The analog output is set to maximum value on
-power up or reset. This doesn't do much on the test Intel SE440BX-2.
-
-Voltage Monitor
-
-Voltage (IN) measurement is internally scaled:
-
-    nr  label       nominal     maximum   resolution
-                      mV          mV         mV
-    0   +2.5V        2500        3320       13.0
-    1   Vccp1        2700        3600       14.1
-    2   +3.3V        3300        4380       17.2
-    3     +5V        5000        6640       26.0
-    4    +12V       12000       15940       62.5
-    5   Vccp2        2700        3600       14.1
-
-The reading is an unsigned 8-bit value, nominal voltage measurement is
-represented by a reading of 192, being 3/4 of the measurement range.
-
-An alarm is asserted for any voltage going below or above the set limits.
-
-The driver reports and accepts voltage limits scaled to the above table.
-
-VID Monitor
------------
-The chip has five inputs to read the 5-bit VID and reports the mV value
-based on detected CPU type.
-
-Chassis Intrusion
------------------
-An alarm is asserted when the CI pin goes active high. The ADM9240
-Datasheet has an example of an external temperature sensor driving
-this pin. On an Intel SE440BX-2 the Chassis Intrusion header is
-connected to a normally open switch.
-
-The ADM9240 provides an internal open drain on this line, and may output
-a 20 ms active low pulse to reset an external Chassis Intrusion latch.
-
-Clear the CI latch by writing value 0 to the sysfs intrusion0_alarm file.
-
-Alarm flags reported as 16-bit word
-
-    bit     label               comment
-    ---     -------------       --------------------------
-     0      +2.5 V_Error        high or low limit exceeded
-     1      VCCP_Error          high or low limit exceeded
-     2      +3.3 V_Error        high or low limit exceeded
-     3      +5 V_Error          high or low limit exceeded

-     9      VCCP2_Error         high or low limit exceeded
-    12      Chassis_Error       CI pin went high
-
-Remaining bits are reserved and thus undefined. It is important to note
-that alarm bits may be cleared on read, user-space may latch alarms and
-provide the end-user with a method to clear alarm memory.

-Description
------------
-
-This driver implements support for the Texas Instruments ADS1015/ADS1115.
-
-This device is a 12/16-bit A-D converter with 4 inputs.
-
-The inputs can be used single ended or in certain differential combinations.
-
-The inputs can be made available by 8 sysfs input files in0_input - in7_input:
-in0: Voltage over AIN0 and AIN1.
-in1: Voltage over AIN0 and AIN3.
-in2: Voltage over AIN1 and AIN3.
-in3: Voltage over AIN2 and AIN3.
-in4: Voltage over AIN0 and GND.
-in5: Voltage over AIN1 and GND.
-in6: Voltage over AIN2 and GND.
-in7: Voltage over AIN3 and GND.
-
-Which inputs are available can be configured using platform data or devicetree.
-
-By default all inputs are exported.
-
-Platform Data
--------------
-
-In linux/platform_data/ads1015.h platform data is defined, channel_data contains
-configuration data for the used input combinations:
-- pga is the programmable gain amplifier (values are full scale)
-  0: +/- 6.144 V
-  1: +/- 4.096 V
-  2: +/- 2.048 V
-  3: +/- 1.024 V
-  4: +/- 0.512 V
-  5: +/- 0.256 V
-- data_rate in samples per second
-  0: 128
-  1: 250
-  2: 490
-  3: 920
-  4: 1600
-  5: 2400
-  6: 3300
-
-Example:
-struct ads1015_platform_data data = {
-	.channel_data = {
-		[2] = { .enabled = true, .pga = 1, .data_rate = 0 },
-		[4] = { .enabled = true, .pga = 4, .data_rate = 5 },
-	}
-};
-
-In this case only in2_input (FS +/- 4.096 V, 128 SPS) and in4_input
-(FS +/- 0.512 V, 2400 SPS) would be created.

-Platform data
--------------
-
-The ads7828 driver accepts an optional ads7828_platform_data structure (defined
-in include/linux/platform_data/ads7828.h). The structure fields are:
-
-* diff_input: (bool) Differential operation
-  set to true for differential mode, false for default single ended mode.
-
-* ext_vref: (bool) External reference
-  set to true if it operates with an external reference, false for default
-  internal reference.
-
-* vref_mv: (unsigned int) Voltage reference
-  if using an external reference, set this to the reference voltage in mV,
-  otherwise it will default to the internal value (2500mV). This value will be
-  bounded with limits accepted by the chip, described in the datasheet.
-
- If no structure is provided, the configuration defaults to single ended
- operation and internal voltage reference (2.5V).
-
-Description
------------
-
-This driver implements support for the Texas Instruments ADS7828 and ADS7830.
-
-The ADS7828 device is a 12-bit 8-channel A/D converter, while the ADS7830 does
-8-bit sampling.
-
-It can operate in single ended mode (8 +ve inputs) or in differential mode,
-where 4 differential pairs can be measured.
-
-The chip also has the facility to use an external voltage reference.  This
-may be required if your hardware supplies the ADS7828 from a 5V supply, see
-the datasheet for more details.
-
-There is no reliable way to identify this chip, so the driver will not scan
-some addresses to try to auto-detect it. That means that you will have to
-statically declare the device in the platform support code.

-Description
------------
-
-The ADT7310/ADT7410 is a temperature sensor with rated temperature range of
--55°C to +150°C. It has a high accuracy of +/-0.5°C and can be operated at a
-resolution of 13 bits (0.0625°C) or 16 bits (0.0078°C). The sensor provides an
-INT pin to indicate that a minimum or maximum temperature set point has been
-exceeded, as well as a critical temperature (CT) pin to indicate that the
-critical temperature set point has been exceeded. Both pins can be set up with a
-common hysteresis of 0°C - 15°C and a fault queue, ranging from 1 to 4 events.
-Both pins can individually set to be active-low or active-high, while the whole
-device can either run in comparator mode or interrupt mode. The ADT7410 supports
-continuous temperature sampling, as well as sampling one temperature value per
-second or even just get one sample on demand for power saving. Besides, it can
-completely power down its ADC, if power management is required.
-
-The ADT7320/ADT7420 is register compatible, the only differences being the
-package, a slightly narrower operating temperature range (-40°C to +150°C), and
-a better accuracy (0.25°C instead of 0.50°C.)
-
-The difference between the ADT7310/ADT7320 and ADT7410/ADT7420 is the control
-interface, the ADT7310 and ADT7320 use SPI while the ADT7410 and ADT7420 use
-I2C.
-
-Configuration Notes
--------------------
-
-Since the device uses one hysteresis value, which is an offset to minimum,
-maximum and critical temperature, it can only be set for temp#_max_hyst.
-However, temp#_min_hyst and temp#_crit_hyst show their corresponding
-hysteresis.
-The device is set to 16 bit resolution and comparator mode.

-Author: Darrick J. Wong
-
-Description
------------
-
-This driver implements support for the Analog Devices ADT7462 chip family.
-
-This chip is a bit of a beast.  It has 8 counters for measuring fan speed.  It
-can also measure 13 voltages or 4 temperatures, or various combinations of the
-two.  See the chip documentation for more details about the exact set of
-configurations.  This driver does not allow one to configure the chip; that is
-left to the system designer.
-
-A sophisticated control system for the PWM outputs is designed into the ADT7462
-that allows fan speed to be adjusted automatically based on any of the three
-temperature sensors. Each PWM output is individually adjustable and
-programmable. Once configured, the ADT7462 will adjust the PWM outputs in
-response to the measured temperatures without further host intervention.  This
-feature can also be disabled for manual control of the PWM's.
-
-Each of the measured inputs (voltage, temperature, fan speed) has
-corresponding high/low limit values. The ADT7462 will signal an ALARM if
-any measured value exceeds either limit.
-
-The ADT7462 samples all inputs continuously. The driver will not read
-the registers more often than once every other second. Further,
-configuration data is only read once per minute.
-
-Special Features
-----------------
-
-The ADT7462 have a 10-bit ADC and can therefore measure temperatures
-with 0.25 degC resolution.
-
-The Analog Devices datasheet is very detailed and describes a procedure for
-determining an optimal configuration for the automatic PWM control.
-
-The driver will report sensor labels when it is able to determine that
-information from the configuration registers.
-
-Configuration Notes
--------------------
-
-Besides standard interfaces driver adds the following:
-
-* PWM Control
-
-* pwm#_auto_point1_pwm and temp#_auto_point1_temp and
-* pwm#_auto_point2_pwm and temp#_auto_point2_temp -
-
-point1: Set the pwm speed at a lower temperature bound.
-point2: Set the pwm speed at a higher temperature bound.
-
-The ADT7462 will scale the pwm between the lower and higher pwm speed when
-the temperature is between the two temperature boundaries.  PWM values range
-from 0 (off) to 255 (full speed).  Fan speed will be set to maximum when the
-temperature sensor associated with the PWM control exceeds temp#_max.

-Configuration Notes
--------------------
-
-Besides standard interfaces driver adds the following:
-
-* PWM Control
-
-* pwm#_auto_point1_pwm and pwm#_auto_point1_temp and
-* pwm#_auto_point2_pwm and pwm#_auto_point2_temp -
-
-point1: Set the pwm speed at a lower temperature bound.
-point2: Set the pwm speed at a higher temperature bound.
-
-The ADT7470 will scale the pwm between the lower and higher pwm speed when
-the temperature is between the two temperature boundaries.  PWM values range
-from 0 (off) to 255 (full speed).  Fan speed will be set to maximum when the
-temperature sensor associated with the PWM control exceeds
-pwm#_auto_point2_temp.
-
-The driver also allows control of the PWM frequency:
-
-* pwm1_freq
-
-The PWM frequency is rounded to the nearest one of:
-
-* 11.0 Hz
-* 14.7 Hz
-* 22.1 Hz
-* 29.4 Hz
-* 35.3 Hz
-* 44.1 Hz
-* 58.8 Hz
-* 88.2 Hz
-* 1.4 kHz
-* 22.5 kHz
-
-Notes
------
-
-The temperature inputs no longer need to be read periodically from userspace in
-order for the automatic pwm algorithm to run.  This was the case for earlier
-versions of the driver.

+Description
+-----------
+
+This driver implements support for the Analog Devices ADT7470 chip.  There may
+be other chips that implement this interface.
+
+The ADT7470 uses the 2-wire interface compatible with the SMBus 2.0
+specification. Using an analog to digital converter it measures up to ten (10)
+external temperatures. It has four (4) 16-bit counters for measuring fan speed.
+There are four (4) PWM outputs that can be used to control fan speed.
+
+A sophisticated control system for the PWM outputs is designed into the ADT7470
+that allows fan speed to be adjusted automatically based on any of the ten
+temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the ADT7470 will adjust the PWM outputs in
+response to the measured temperatures with further host intervention.  This
+feature can also be disabled for manual control of the PWM's.

-Special Features
-----------------
-
-The ADT747x has a 10-bit ADC and can therefore measure temperatures
-with a resolution of 0.25 degree Celsius. Temperature readings can be
-configured either for two's complement format or "Offset 64" format,
-wherein 64 is subtracted from the raw value to get the temperature value.
-
-The datasheet is very detailed and describes a procedure for determining
-an optimal configuration for the automatic PWM control.
-
-Fan Speed Control
------------------
-
-The driver exposes two trip points per PWM channel.
-
-point1: Set the PWM speed at the lower temperature bound
-point2: Set the PWM speed at the higher temperature bound
-
-The ADT747x will scale the PWM linearly between the lower and higher PWM
-speed when the temperature is between the two temperature boundaries.
-Temperature boundaries are associated to temperature channels rather than
-PWM outputs, and a given PWM output can be controlled by several temperature
-channels. As a result, the ADT747x may compute more than one PWM value
-for a channel at a given time, in which case the maximum value (fastest
-fan speed) is applied. PWM values range from 0 (off) to 255 (full speed).
-
-Fan speed may be set to maximum when the temperature sensor associated with
-the PWM control exceeds temp#_max.
-
-At Tmin - hysteresis the PWM output can either be off (0% duty cycle) or at the
-minimum (i.e. auto_point1_pwm). This behaviour can be configured using the
-pwm[1-*]_stall_disable sysfs attribute. A value of 0 means the fans will shut
-off. A value of 1 means the fans will run at auto_point1_pwm.
-
-The responsiveness of the ADT747x to temperature changes can be configured.
-This allows smoothing of the fan speed transition. To set the transition time
-set the value in ms in the temp[1-*]_smoothing sysfs attribute.
-
-Notes
------
-
-The nVidia binary driver presents an ADT7473 chip via an on-card i2c bus.
-Unfortunately, they fail to set the i2c adapter class, so this driver may
-fail to find the chip until the nvidia driver is patched.

-Description
------------
-
-This driver implements support for the Asus ASB100 and ASB100-A "Bach".
-These are custom ASICs available only on Asus mainboards. Asus refuses to
-supply a datasheet for these chips. Thanks go to many people who helped
-investigate their hardware, including:
-
-Vitaly V. Bursov
-Alexander van Kaam (author of MBM for Windows)
-Bertrik Sikken
-
-The ASB100 implements seven voltage sensors, three fan rotation speed
-sensors, four temperature sensors, VID lines and alarms. In addition to
-these, the ASB100-A also implements a single PWM controller for fans 2 and
-3 (i.e. one setting controls both.) If you have a plain ASB100, the PWM
-controller will simply not work (or maybe it will for you... it doesn't for
-me).
-
-Temperatures are measured and reported in degrees Celsius.
-
-Fan speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit.
-
-Voltage sensors (also known as IN sensors) report values in volts.
-
-The VID lines encode the core voltage value: the voltage level your
-processor should work with. This is hardcoded by the mainboard and/or
-processor itself. It is a value in volts.
-
-Alarms: (TODO question marks indicate may or may not work)

-I.e. it behaves the same as w83781d.
-
-(2) The min and max registers for these values appear to

-Kernel driver asc7621
-==================
-
-Supported chips:
-    Andigilog aSC7621 and aSC7621a
-    Prefix: 'asc7621'
-    Addresses scanned: I2C 0x2c, 0x2d, 0x2e
-    Datasheet: http://www.fairview5.com/linux/asc7621/asc7621.pdf
-
-Author:
-		George Joseph
-
-Description provided by Dave Pivin @ Andigilog:
-
-Andigilog has both the PECI and pre-PECI versions of the Heceta-6, as
-Intel calls them. Heceta-6e has high frequency PWM and Heceta-6p has
-added PECI and a 4th thermal zone. The Andigilog aSC7611 is the
-Heceta-6e part and aSC7621 is the Heceta-6p part. They are both in
-volume production, shipping to Intel and their subs.
-
-We have enhanced both parts relative to the governing Intel
-specification. First enhancement is temperature reading resolution. We
-have used registers below 20h for vendor-specific functions in addition
-to those in the Intel-specified vendor range.
-
-Our conversion process produces a result that is reported as two bytes.
-The fan speed control uses this finer value to produce a "step-less" fan
-PWM output. These two bytes are "read-locked" to guarantee that once a
-high or low byte is read, the other byte is locked-in until after the
-next read of any register. So to get an atomic reading, read high or low
-byte, then the very next read should be the opposite byte. Our data
-sheet says 10-bits of resolution, although you may find the lower bits
-are active, they are not necessarily reliable or useful externally. We
-chose not to mask them.
-
-We employ significant filtering that is user tunable as described in the
-data sheet. Our temperature reports and fan PWM outputs are very smooth
-when compared to the competition, in addition to the higher resolution
-temperature reports. The smoother PWM output does not require user
-intervention.
-
-We offer GPIO features on the former VID pins. These are open-drain
-outputs or inputs and may be used as general purpose I/O or as alarm
-outputs that are based on temperature limits. These are in 19h and 1Ah.
-
-We offer flexible mapping of temperature readings to thermal zones. Any
-temperature may be mapped to any zone, which has a default assignment
-that follows Intel's specs.
-
-Since there is a fan to zone assignment that allows for the "hotter" of
-a set of zones to control the PWM of an individual fan, but there is no
-indication to the user, we have added an indicator that shows which zone
-is currently controlling the PWM for a given fan. This is in register
-00h.
-
-Both remote diode temperature readings may be given an offset value such
-that the reported reading as well as the temperature used to determine
-PWM may be offset for system calibration purposes.
-
-PECI Extended configuration allows for having more than two domains per
-PECI address and also provides an enabling function for each PECI
-address. One could use our flexible zone assignment to have a zone
-assigned to up to 4 PECI addresses. This is not possible in the default
-Intel configuration. This would be useful in multi-CPU systems with
-individual fans on each that would benefit from individual fan control.
-This is in register 0Eh.
-
-The tachometer measurement system is flexible and able to adapt to many
-fan types. We can also support pulse-stretched PWM so that 3-wire fans
-may be used. These characteristics are in registers 04h to 07h.
-
-Finally, we have added a tach disable function that turns off the tach
-measurement system for individual tachs in order to save power. That is
-in register 75h.

-aSC7621 Product Description
-
-The aSC7621 has a two wire digital interface compatible with SMBus 2.0.
-Using a 10-bit ADC, the aSC7621 measures the temperature of two remote diode
-connected transistors as well as its own die. Support for Platform
-Environmental Control Interface (PECI) is included.
-
-Using temperature information from these four zones, an automatic fan speed
-control algorithm is employed to minimize acoustic impact while achieving
-recommended CPU temperature under varying operational loads.
-
-To set fan speed, the aSC7621 has three independent pulse width modulation
-(PWM) outputs that are controlled by one, or a combination of three,
-temperature zones. Both high- and low-frequency PWM ranges are supported.
-
-The aSC7621 also includes a digital filter that can be invoked to smooth
-temperature readings for better control of fan speed and minimum acoustic
-impact.
-
-The aSC7621 has tachometer inputs to measure fan speed on up to four fans.
-Limit and status registers for all measured values are included to alert
-the system host that any measurements are outside of programmed limits
-via status registers.
-
-System voltages of VCCP, 2.5V, 3.3V, 5.0V, and 12V motherboard power are
-monitored efficiently with internal scaling resistors.

-Description
------------
-This driver permits reading the DTS (Digital Temperature Sensor) embedded
-inside Intel CPUs. This driver can read both the per-core and per-package
-temperature using the appropriate sensors. The per-package sensor is new;
-as of now, it is present only in the SandyBridge platform. The driver will
-show the temperature of all cores inside a package under a single device
-directory inside hwmon.
-
-Temperature is measured in degrees Celsius and measurement resolution is
-1 degree C. Valid temperatures are from 0 to TjMax degrees C, because
-the actual value of temperature register is in fact a delta from TjMax.
-
-Temperature known as TjMax is the maximum junction temperature of processor,
-which depends on the CPU model. See table below. At this temperature, protection
-mechanism will perform actions to forcibly cool down the processor. Alarm
-may be raised, if the temperature grows enough (more than TjMax) to trigger
-the Out-Of-Spec bit. Following table summarizes the exported sysfs files:
-
-All Sysfs entries are named with their core_id (represented here by 'X').
-tempX_input	 - Core temperature (in millidegrees Celsius).
-tempX_max	 - All cooling devices should be turned on (on Core2).
-tempX_crit	 - Maximum junction temperature (in millidegrees Celsius).
-tempX_crit_alarm - Set when Out-of-spec bit is set, never clears.
-		   Correct CPU operation is no longer guaranteed.
-tempX_label	 - Contains string "Core X", where X is processor
-		   number. For Package temp, this will be "Physical id Y",
-		   where Y is the package number.
-
-On CPU models which support it, TjMax is read from a model-specific register.
-On other models, it is set to an arbitrary value based on weak heuristics.
-If these heuristics don't work for you, you can pass the correct TjMax value
-as a module parameter (tjmax).

-
-Description
------------
-
-This driver implements support for the hardware monitoring capabilities of the
-SMSC DME1737 and Asus A8000 (which are the same), SMSC SCH5027, SCH311x,
-and SCH5127 Super-I/O chips. These chips feature monitoring of 3 temp sensors
-temp[1-3] (2 remote diodes and 1 internal), 8 voltages in[0-7] (7 external and
-1 internal) and up to 6 fan speeds fan[1-6]. Additionally, the chips implement
-up to 5 PWM outputs pwm[1-3,5-6] for controlling fan speeds both manually and
-automatically.
-
-For the DME1737, A8000 and SCH5027, fan[1-2] and pwm[1-2] are always present.
-Fan[3-6] and pwm[3,5-6] are optional features and their availability depends on
-the configuration of the chip. The driver will detect which features are
-present during initialization and create the sysfs attributes accordingly.
-
-For the SCH311x and SCH5127, fan[1-3] and pwm[1-3] are always present and
-fan[4-6] and pwm[5-6] don't exist.
-
-The hardware monitoring features of the DME1737, A8000, and SCH5027 are only
-accessible via SMBus, while the SCH311x and SCH5127 only provide access via
-the ISA bus. The driver will therefore register itself as an I2C client driver
-if it detects a DME1737, A8000, or SCH5027 and as a platform driver if it
-detects a SCH311x or SCH5127 chip.
-
-
-Voltage Monitoring
-------------------
-
-The voltage inputs are sampled with 12-bit resolution and have internal
-scaling resistors. The values returned by the driver therefore reflect true
-millivolts and don't need scaling. The voltage inputs are mapped as follows
-(the last column indicates the input ranges):
-
-DME1737, A8000:
-	in0: +5VTR	(+5V standby)		0V - 6.64V

-	in7: Vtrip	(+1.5V)			0V - 1.99V
-
-Each voltage input has associated min and max limits which trigger an alarm
-when crossed.
-
-
-Temperature Monitoring
-----------------------
-
-Temperatures are measured with 12-bit resolution and reported in millidegree
-Celsius. The chip also features offsets for all 3 temperature inputs which -
-when programmed - get added to the input readings. The chip does all the
-scaling by itself and the driver therefore reports true temperatures that don't
-need any user-space adjustments. The temperature inputs are mapped as follows
-(the last column indicates the input ranges):
-
-	temp1: Remote diode 1 (3904 type) temperature	-127C - +127C
-	temp2: DME1737 internal temperature		-127C - +127C
-	temp3: Remote diode 2 (3904 type) temperature	-127C - +127C
-
-Each temperature input has associated min and max limits which trigger an alarm
-when crossed. Additionally, each temperature input has a fault attribute that
-returns 1 when a faulty diode or an unconnected input is detected and 0
-otherwise.
-
-
-Fan Monitoring
---------------
-
-Fan RPMs are measured with 16-bit resolution. The chip provides inputs for 6
-fan tachometers. All 6 inputs have an associated min limit which triggers an
-alarm when crossed. Fan inputs 1-4 provide type attributes that need to be set
-to the number of pulses per fan revolution that the connected tachometer
-generates. Supported values are 1, 2, and 4. Fan inputs 5-6 only support fans
-that generate 2 pulses per revolution. Fan inputs 5-6 also provide a max
-attribute that needs to be set to the maximum attainable RPM (fan at 100% duty-
-cycle) of the input. The chip adjusts the sampling rate based on this value.
-
-
-PWM Output Control
-------------------
-
-This chip features 5 PWM outputs. PWM outputs 1-3 are associated with fan
-inputs 1-3 and PWM outputs 5-6 are associated with fan inputs 5-6. PWM outputs
-1-3 can be configured to operate either in manual or automatic mode by setting
-the appropriate enable attribute accordingly. PWM outputs 5-6 can only operate
-in manual mode, their enable attributes are therefore read-only. When set to
-manual mode, the fan speed is set by writing the duty-cycle value to the
-appropriate PWM attribute. In automatic mode, the PWM attribute returns the
-current duty-cycle as set by the fan controller in the chip. All PWM outputs
-support the setting of the output frequency via the freq attribute.
-
-In automatic mode, the chip supports the setting of the PWM ramp rate which
-defines how fast the PWM output is adjusting to changes of the associated
-temperature input. Associating PWM outputs to temperature inputs is done via
-temperature zones. The chip features 3 zones whose assignments to temperature
-inputs is static and determined during initialization. These assignments can
-be retrieved via the zone[1-3]_auto_channels_temp attributes. Each PWM output
-is assigned to one (or hottest of multiple) temperature zone(s) through the
-pwm[1-3]_auto_channels_zone attributes. Each PWM output has 3 distinct output
-duty-cycles: full, low, and min. Full is internally hard-wired to 255 (100%)
-and low and min can be programmed via pwm[1-3]_auto_point1_pwm and
-pwm[1-3]_auto_pwm_min, respectively. The thermal thresholds of the zones are
-programmed via zone[1-3]_auto_point[1-3]_temp and
-zone[1-3]_auto_point1_temp_hyst:
-
-	pwm[1-3]_auto_point2_pwm	full-speed duty-cycle (255, i.e., 100%)
-	pwm[1-3]_auto_point1_pwm	low-speed duty-cycle
-	pwm[1-3]_auto_pwm_min		min-speed duty-cycle
-
-	zone[1-3]_auto_point3_temp	full-speed temp (all outputs)
-	zone[1-3]_auto_point2_temp	full-speed temp
-	zone[1-3]_auto_point1_temp	low-speed temp
-	zone[1-3]_auto_point1_temp_hyst	min-speed temp
-
-The chip adjusts the output duty-cycle linearly in the range of auto_point1_pwm
-to auto_point2_pwm if the temperature of the associated zone is between
-auto_point1_temp and auto_point2_temp. If the temperature drops below the
-auto_point1_temp_hyst value, the output duty-cycle is set to the auto_pwm_min
-value which only supports two values: 0 or auto_point1_pwm. That means that the
-fan either turns completely off or keeps spinning with the low-speed
-duty-cycle. If any of the temperatures rise above the auto_point3_temp value,
-all PWM outputs are set to 100% duty-cycle.
-
-Following is another representation of how the chip sets the output duty-cycle
-based on the temperature of the associated thermal zone:
-
-			Duty-Cycle	Duty-Cycle
-	Temperature	Rising Temp	Falling Temp
-	-----------	-----------	------------
-	full-speed	full-speed	full-speed
-
-			< linearly adjusted duty-cycle >
-
-	low-speed	low-speed	low-speed
-			min-speed	low-speed
-	min-speed	min-speed	min-speed
-			min-speed	min-speed

+
+Description
+-----------
+
+This driver implements support for the hardware monitoring capabilities of the
+SMSC DME1737 and Asus A8000 (which are the same), SMSC SCH5027, SCH311x,
+and SCH5127 Super-I/O chips. These chips feature monitoring of 3 temp sensors
+temp[1-3] (2 remote diodes and 1 internal), 8 voltages in[0-7] (7 external and
+1 internal) and up to 6 fan speeds fan[1-6]. Additionally, the chips implement
+up to 5 PWM outputs pwm[1-3,5-6] for controlling fan speeds both manually and
+automatically.
+
+For the DME1737, A8000 and SCH5027, fan[1-2] and pwm[1-2] are always present.
+Fan[3-6] and pwm[3,5-6] are optional features and their availability depends on
+the configuration of the chip. The driver will detect which features are
+present during initialization and create the sysfs attributes accordingly.
+
+For the SCH311x and SCH5127, fan[1-3] and pwm[1-3] are always present and
+fan[4-6] and pwm[5-6] don't exist.
+
+The hardware monitoring features of the DME1737, A8000, and SCH5027 are only
+accessible via SMBus, while the SCH311x and SCH5127 only provide access via
+the ISA bus. The driver will therefore register itself as an I2C client driver
+if it detects a DME1737, A8000, or SCH5027 and as a platform driver if it
+detects a SCH311x or SCH5127 chip.
+
+
+Voltage Monitoring
+------------------
+
+The voltage inputs are sampled with 12-bit resolution and have internal
+scaling resistors. The values returned by the driver therefore reflect true
+millivolts and don't need scaling. The voltage inputs are mapped as follows
+(the last column indicates the input ranges):
+
+DME1737, A8000::
+
+	in0: +5VTR	(+5V standby)		0V - 6.64V
+	in1: Vccp	(processor core)	0V - 3V
+	in2: VCC	(internal +3.3V)	0V - 4.38V
+	in3: +5V				0V - 6.64V
+	in4: +12V				0V - 16V
+	in5: VTR	(+3.3V standby)		0V - 4.38V
+	in6: Vbat	(+3.0V)			0V - 4.38V
+
+SCH311x::
+
+	in0: +2.5V				0V - 3.32V
+	in1: Vccp	(processor core)	0V - 2V
+	in2: VCC	(internal +3.3V)	0V - 4.38V
+	in3: +5V				0V - 6.64V
+	in4: +12V				0V - 16V
+	in5: VTR	(+3.3V standby)		0V - 4.38V
+	in6: Vbat	(+3.0V)			0V - 4.38V
+
+SCH5027::
+
+	in0: +5VTR	(+5V standby)		0V - 6.64V
+	in1: Vccp	(processor core)	0V - 3V
+	in2: VCC	(internal +3.3V)	0V - 4.38V
+	in3: V2_IN				0V - 1.5V
+	in4: V1_IN				0V - 1.5V
+	in5: VTR	(+3.3V standby)		0V - 4.38V
+	in6: Vbat	(+3.0V)			0V - 4.38V
+
+SCH5127::
+
+	in0: +2.5				0V - 3.32V
+	in1: Vccp	(processor core)	0V - 3V
+	in2: VCC	(internal +3.3V)	0V - 4.38V
+	in3: V2_IN				0V - 1.5V
+	in4: V1_IN				0V - 1.5V
+	in5: VTR	(+3.3V standby)		0V - 4.38V
+	in6: Vbat	(+3.0V)			0V - 4.38V
+	in7: Vtrip	(+1.5V)			0V - 1.99V
+
+Each voltage input has associated min and max limits which trigger an alarm
+when crossed.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are measured with 12-bit resolution and reported in millidegree
+Celsius. The chip also features offsets for all 3 temperature inputs which -
+when programmed - get added to the input readings. The chip does all the
+scaling by itself and the driver therefore reports true temperatures that don't
+need any user-space adjustments. The temperature inputs are mapped as follows
+(the last column indicates the input ranges)::
+
+	temp1: Remote diode 1 (3904 type) temperature	-127C - +127C
+	temp2: DME1737 internal temperature		-127C - +127C
+	temp3: Remote diode 2 (3904 type) temperature	-127C - +127C
+
+Each temperature input has associated min and max limits which trigger an alarm
+when crossed. Additionally, each temperature input has a fault attribute that
+returns 1 when a faulty diode or an unconnected input is detected and 0
+otherwise.
+
+
+Fan Monitoring
+--------------
+
+Fan RPMs are measured with 16-bit resolution. The chip provides inputs for 6
+fan tachometers. All 6 inputs have an associated min limit which triggers an
+alarm when crossed. Fan inputs 1-4 provide type attributes that need to be set
+to the number of pulses per fan revolution that the connected tachometer
+generates. Supported values are 1, 2, and 4. Fan inputs 5-6 only support fans
+that generate 2 pulses per revolution. Fan inputs 5-6 also provide a max
+attribute that needs to be set to the maximum attainable RPM (fan at 100% duty-
+cycle) of the input. The chip adjusts the sampling rate based on this value.
+
+
+PWM Output Control
+------------------
+
+This chip features 5 PWM outputs. PWM outputs 1-3 are associated with fan
+inputs 1-3 and PWM outputs 5-6 are associated with fan inputs 5-6. PWM outputs
+1-3 can be configured to operate either in manual or automatic mode by setting
+the appropriate enable attribute accordingly. PWM outputs 5-6 can only operate
+in manual mode, their enable attributes are therefore read-only. When set to
+manual mode, the fan speed is set by writing the duty-cycle value to the
+appropriate PWM attribute. In automatic mode, the PWM attribute returns the
+current duty-cycle as set by the fan controller in the chip. All PWM outputs
+support the setting of the output frequency via the freq attribute.
+
+In automatic mode, the chip supports the setting of the PWM ramp rate which
+defines how fast the PWM output is adjusting to changes of the associated
+temperature input. Associating PWM outputs to temperature inputs is done via
+temperature zones. The chip features 3 zones whose assignments to temperature
+inputs is static and determined during initialization. These assignments can
+be retrieved via the zone[1-3]_auto_channels_temp attributes. Each PWM output
+is assigned to one (or hottest of multiple) temperature zone(s) through the
+pwm[1-3]_auto_channels_zone attributes. Each PWM output has 3 distinct output
+duty-cycles: full, low, and min. Full is internally hard-wired to 255 (100%)
+and low and min can be programmed via pwm[1-3]_auto_point1_pwm and
+pwm[1-3]_auto_pwm_min, respectively. The thermal thresholds of the zones are
+programmed via zone[1-3]_auto_point[1-3]_temp and
+zone[1-3]_auto_point1_temp_hyst:
+
+	=============================== =======================================
+	pwm[1-3]_auto_point2_pwm	full-speed duty-cycle (255, i.e., 100%)
+	pwm[1-3]_auto_point1_pwm	low-speed duty-cycle
+	pwm[1-3]_auto_pwm_min		min-speed duty-cycle
+
+	zone[1-3]_auto_point3_temp	full-speed temp (all outputs)
+	zone[1-3]_auto_point2_temp	full-speed temp
+	zone[1-3]_auto_point1_temp	low-speed temp
+	zone[1-3]_auto_point1_temp_hyst	min-speed temp
+	=============================== =======================================
+
+The chip adjusts the output duty-cycle linearly in the range of auto_point1_pwm
+to auto_point2_pwm if the temperature of the associated zone is between
+auto_point1_temp and auto_point2_temp. If the temperature drops below the
+auto_point1_temp_hyst value, the output duty-cycle is set to the auto_pwm_min
+value which only supports two values: 0 or auto_point1_pwm. That means that the
+fan either turns completely off or keeps spinning with the low-speed
+duty-cycle. If any of the temperatures rise above the auto_point3_temp value,
+all PWM outputs are set to 100% duty-cycle.
+
+Following is another representation of how the chip sets the output duty-cycle
+based on the temperature of the associated thermal zone:
+
+	=============== =============== =================
+	Temperature	Duty-Cycle	Duty-Cycle
+			Rising Temp	Falling Temp
+	=============== =============== =================
+	full-speed	full-speed	full-speed
+
+	-		< linearly	-
+			adjusted
+			duty-cycle >
+
+	low-speed	low-speed	low-speed
+	-		min-speed	low-speed
+	min-speed	min-speed	min-speed
+	-		min-speed	min-speed

-Module Parameters
-------------------
-
-* polarity int
-  Output's polarity: 0 = active high, 1 = active low
-
-Description
------------
-
-The DS1621 is a (one instance) digital thermometer and thermostat. It has
-both high and low temperature limits which can be user defined (i.e.
-programmed into non-volatile on-chip registers). Temperature range is -55
-degree Celsius to +125 in 0.5 increments. You may convert this into a
-Fahrenheit range of -67 to +257 degrees with 0.9 steps. If polarity
-parameter is not provided, original value is used.
-
-As for the thermostat, behavior can also be programmed using the polarity
-toggle. On the one hand ("heater"), the thermostat output of the chip,
-Tout, will trigger when the low limit temperature is met or underrun and
-stays high until the high limit is met or exceeded. On the other hand
-("cooler"), vice versa. That way "heater" equals "active low", whereas
-"conditioner" equals "active high". Please note that the DS1621 data sheet
-is somewhat misleading in this point since setting the polarity bit does
-not simply invert Tout.
-
-A second thing is that, during extensive testing, Tout showed a tolerance
-of up to +/- 0.5 degrees even when compared against precise temperature
-readings. Be sure to have a high vs. low temperature limit gap of al least
-1.0 degree Celsius to avoid Tout "bouncing", though!
-
-The alarm bits are set when the high or low limits are met or exceeded and
-are reset by the module as soon as the respective temperature ranges are
-left.
-
-The alarm registers are in no way suitable to find out about the actual
-status of Tout. They will only tell you about its history, whether or not
-any of the limits have ever been met or exceeded since last power-up or
-reset. Be aware: When testing, it showed that the status of Tout can change
-with neither of the alarms set.
-
-Since there is no version or vendor identification register, there is
-no unique identification for these devices. Therefore, explicit device
-instantiation is required for correct device identification and functionality
-(one device per address in this address range: 0x48..0x4f).
-
-The DS1625 is pin compatible and functionally equivalent with the DS1621,
-but the DS1621 is meant to replace it. The DS1631, DS1721, and DS1731 are
-also pin compatible with the DS1621 and provide multi-resolution support.
-
-Additionally, the DS1721 data sheet says the temperature flags (THF and TLF)
-are used internally, however, these flags do get set and cleared as the actual
-temperature crosses the min or max settings (which by default are set to 75
-and 80 degrees respectively).
-
-Temperature Conversion:
------------------------
-DS1621 - 750ms (older devices may take up to 1000ms)
-DS1625 - 500ms
-DS1631 - 93ms..750ms for 9..12 bits resolution, respectively.
-DS1721 - 93ms..750ms for 9..12 bits resolution, respectively.
-DS1731 - 93ms..750ms for 9..12 bits resolution, respectively.
-
-Note:
-On the DS1621, internal access to non-volatile registers may last for 10ms
-or less (unverified on the other devices).
-
-Temperature Accuracy:
----------------------
-DS1621: +/- 0.5 degree Celsius (from 0 to +70 degrees)
-DS1625: +/- 0.5 degree Celsius (from 0 to +70 degrees)
-DS1631: +/- 0.5 degree Celsius (from 0 to +70 degrees)
-DS1721: +/- 1.0 degree Celsius (from -10 to +85 degrees)
-DS1731: +/- 1.0 degree Celsius (from -10 to +85 degrees)
-
-Note:
-Please refer to the device datasheets for accuracy at other temperatures.
-
-Temperature Resolution:
------------------------
-As mentioned above, the DS1631, DS1721, and DS1731 provide multi-resolution
-support, which is achieved via the R0 and R1 config register bits, where:
-
-R0..R1
-------
- 0  0 => 9 bits, 0.5 degrees Celsius
- 1  0 => 10 bits, 0.25 degrees Celsius
- 0  1 => 11 bits, 0.125 degrees Celsius
- 1  1 => 12 bits, 0.0625 degrees Celsius
-
-Note:
-At initial device power-on, the default resolution is set to 12-bits.
-
-The resolution mode for the DS1631, DS1721, or DS1731 can be changed from
-userspace, via the device 'update_interval' sysfs attribute. This attribute
-will normalize the range of input values to the device maximum resolution
-values defined in the datasheet as follows:
-
-Resolution    Conversion Time    Input Range
- (C/LSB)       (msec)             (msec)
-------------------------------------------------
-0.5             93.75              0....94
-0.25            187.5              95...187
-0.125           375                188..375
-0.0625          750                376..infinity
-------------------------------------------------
-
-The following examples show how the 'update_interval' attribute can be
-used to change the conversion time:
-
-$ cat update_interval
-750
-$ cat temp1_input
-22062
-$
-$ echo 300 > update_interval
-$ cat update_interval
-375
-$ cat temp1_input
-22125
-$
-$ echo 150 > update_interval
-$ cat update_interval
-188
-$ cat temp1_input
-22250
-$
-$ echo 1 > update_interval
-$ cat update_interval
-94
-$ cat temp1_input
-22000
-$
-$ echo 1000 > update_interval
-$ cat update_interval
-750
-$ cat temp1_input
-22062
-$
-
-As shown, the ds1621 driver automatically adjusts the 'update_interval'
-user input, via a step function. Reading back the 'update_interval' value
-after a write operation provides the conversion time used by the device.
-
-Mathematically, the resolution can be derived from the conversion time
-via the following function:
-
-   g(x) = 0.5 * [minimum_conversion_time/x]
-
-where:
- -> 'x' = the output from 'update_interval'
- -> 'g(x)' = the resolution in degrees C per LSB.
- -> 93.75ms = minimum conversion time

-Description
------------
-
-The Standard Microsystems Corporation (SMSC) / Microchip EMC14xx chips
-contain up to four temperature sensors. EMC14x2 support two sensors
-(one internal, one external). EMC14x3 support three sensors (one internal,
-two external), and EMC14x4 support four sensors (one internal, three
-external).
-
-The chips implement three limits for each sensor: low (tempX_min), high
-(tempX_max) and critical (tempX_crit.) The chips also implement an
-hysteresis mechanism which applies to all limits. The relative difference
-is stored in a single register on the chip, which means that the relative
-difference between the limit and its hysteresis is always the same for
-all three limits.
-
-This implementation detail implies the following:
-* When setting a limit, its hysteresis will automatically follow, the
-  difference staying unchanged. For example, if the old critical limit
-  was 80 degrees C, and the hysteresis was 75 degrees C, and you change
-  the critical limit to 90 degrees C, then the hysteresis will
-  automatically change to 85 degrees C.
-* The hysteresis values can't be set independently. We decided to make
-  only temp1_crit_hyst writable, while all other hysteresis attributes
-  are read-only. Setting temp1_crit_hyst writes the difference between
-  temp1_crit_hyst and temp1_crit into the chip, and the same relative
-  hysteresis applies automatically to all other limits.
-* The limits should be set before the hysteresis.

+Description
+-----------
+
+The Standard Microsystems Corporation (SMSC) / Microchip EMC14xx chips
+contain up to four temperature sensors. EMC14x2 support two sensors
+(one internal, one external). EMC14x3 support three sensors (one internal,
+two external), and EMC14x4 support four sensors (one internal, three
+external).
+
+The chips implement three limits for each sensor: low (tempX_min), high
+(tempX_max) and critical (tempX_crit.) The chips also implement an
+hysteresis mechanism which applies to all limits. The relative difference
+is stored in a single register on the chip, which means that the relative
+difference between the limit and its hysteresis is always the same for
+all three limits.
+
+This implementation detail implies the following:
+
+* When setting a limit, its hysteresis will automatically follow, the
+  difference staying unchanged. For example, if the old critical limit
+  was 80 degrees C, and the hysteresis was 75 degrees C, and you change
+  the critical limit to 90 degrees C, then the hysteresis will
+  automatically change to 85 degrees C.
+* The hysteresis values can't be set independently. We decided to make
+  only temp1_crit_hyst writable, while all other hysteresis attributes
+  are read-only. Setting temp1_crit_hyst writes the difference between
+  temp1_crit_hyst and temp1_crit into the chip, and the same relative
+  hysteresis applies automatically to all other limits.
+* The limits should be set before the hysteresis.

-Description
------------
-
-The Standard Microsystems Corporation (SMSC) EMC2103 chips
-contain up to 4 temperature sensors and a single fan controller.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 1, the lowest
-representable value is 480 RPM.
-
-This driver supports RPM based control, to use this a fan target
-should be written to fan1_target and pwm1_enable should be set to 3.
-
-The 2103-2 and 2103-4 variants have a third temperature sensor, which can
-be connected to two anti-parallel diodes.  These values can be read
-as temp3 and temp4.  If only one diode is attached to this channel, temp4
-will show as "fault".  The module parameter "apd=0" can be used to suppress
-this 4th channel when anti-parallel diodes are not fitted.

-Description
------------
-
-The Fintek F71805F/FG Super I/O chip includes complete hardware monitoring
-capabilities. It can monitor up to 9 voltages (counting its own power
-source), 3 fans and 3 temperature sensors.
-
-This chip also has fan controlling features, using either DC or PWM, in
-three different modes (one manual, two automatic).
-
-The Fintek F71872F/FG Super I/O chip is almost the same, with two
-additional internal voltages monitored (VSB and battery). It also features
-6 VID inputs. The VID inputs are not yet supported by this driver.
-
-The Fintek F71806F/FG Super-I/O chip is essentially the same as the
-F71872F/FG, and is undistinguishable therefrom.
-
-The driver assumes that no more than one chip is present, which seems
-reasonable.
-
-
-Voltage Monitoring
-------------------
-
-Voltages are sampled by an 8-bit ADC with a LSB of 8 mV. The supported
-range is thus from 0 to 2.040 V. Voltage values outside of this range
-need external resistors. An exception is in0, which is used to monitor
-the chip's own power source (+3.3V), and is divided internally by a
-factor 2. For the F71872F/FG, in9 (VSB) and in10 (battery) are also
-divided internally by a factor 2.
-
-The two LSB of the voltage limit registers are not used (always 0), so
-you can only set the limits in steps of 32 mV (before scaling).
-
-The wirings and resistor values suggested by Fintek are as follow:
-
-        pin                                           expected

-(1) Depends on your hardware setup.

-
-These values can be used as hints at best, as motherboard manufacturers
-are free to use a completely different setup. As a matter of fact, the
-Jetway K8M8MS uses a significantly different setup. You will have to
-find out documentation about your own motherboard, and edit sensors.conf
-accordingly.
-
-Each voltage measured has associated low and high limits, each of which
-triggers an alarm when crossed.
-
-
-Fan Monitoring
---------------
-
-Fan rotation speeds are reported as 12-bit values from a gated clock
-signal. Speeds down to 366 RPM can be measured. There is no theoretical
-high limit, but values over 6000 RPM seem to cause problem. The effective
-resolution is much lower than you would expect, the step between different
-register values being 10 rather than 1.
-
-The chip assumes 2 pulse-per-revolution fans.
-
-An alarm is triggered if the rotation speed drops below a programmable
-limit or is too low to be measured.
-
-
-Temperature Monitoring
-----------------------
-
-Temperatures are reported in degrees Celsius. Each temperature measured
-has a high limit, those crossing triggers an alarm. There is an associated
-hysteresis value, below which the temperature has to drop before the
-alarm is cleared.
-
-All temperature channels are external, there is no embedded temperature
-sensor. Each channel can be used for connecting either a thermal diode
-or a thermistor. The driver reports the currently selected mode, but
-doesn't allow changing it. In theory, the BIOS should have configured
-everything properly.
-
-
-Fan Control
------------
-
-Both PWM (pulse-width modulation) and DC fan speed control methods are
-supported. The right one to use depends on external circuitry on the
-motherboard, so the driver assumes that the BIOS set the method
-properly. The driver will report the method, but won't let you change
-it.
-
-When the PWM method is used, you can select the operating frequency,
-from 187.5 kHz (default) to 31 Hz. The best frequency depends on the
-fan model. As a rule of thumb, lower frequencies seem to give better
-control, but may generate annoying high-pitch noise. So a frequency just
-above the audible range, such as 25 kHz, may be a good choice; if this
-doesn't give you good linear control, try reducing it. Fintek recommends
-not going below 1 kHz, as the fan tachometers get confused by lower
-frequencies as well.
-
-When the DC method is used, Fintek recommends not going below 5 V, which
-corresponds to a pwm value of 106 for the driver. The driver doesn't
-enforce this limit though.
-
-Three different fan control modes are supported; the mode number is written
-to the pwm<n>_enable file.
-
-* 1: Manual mode
-  You ask for a specific PWM duty cycle or DC voltage by writing to the
-  pwm<n> file.
-
-* 2: Temperature mode
-  You define 3 temperature/fan speed trip points using the
-  pwm<n>_auto_point<m>_temp and _fan files. These define a staircase
-  relationship between temperature and fan speed with two additional points
-  interpolated between the values that you define. When the temperature
-  is below auto_point1_temp the fan is switched off.
-
-* 3: Fan speed mode
-  You ask for a specific fan speed by writing to the fan<n>_target file.
-
-Both of the automatic modes require that pwm1 corresponds to fan1, pwm2 to
-fan2 and pwm3 to fan3. Temperature mode also requires that temp1 corresponds
-to pwm1 and fan1, etc.

+properly. The driver will report the method, but won't let you change
+it.
+
+When the PWM method is used, you can select the operating frequency,
+from 187.5 kHz (default) to 31 Hz. The best frequency depends on the
+fan model. As a rule of thumb, lower frequencies seem to give better
+control, but may generate annoying high-pitch noise. So a frequency just
+above the audible range, such as 25 kHz, may be a good choice; if this
+doesn't give you good linear control, try reducing it. Fintek recommends
+not going below 1 kHz, as the fan tachometers get confused by lower
+frequencies as well.
+
+When the DC method is used, Fintek recommends not going below 5 V, which
+corresponds to a pwm value of 106 for the driver. The driver doesn't
+enforce this limit though.
+
+Three different fan control modes are supported; the mode number is written
+to the pwm<n>_enable file.
+
+* 1: Manual mode
+  You ask for a specific PWM duty cycle or DC voltage by writing to the
+  pwm<n> file.
+
+* 2: Temperature mode
+  You define 3 temperature/fan speed trip points using the
+  pwm<n>_auto_point<m>_temp and _fan files. These define a staircase
+  relationship between temperature and fan speed with two additional points
+  interpolated between the values that you define. When the temperature
+  is below auto_point1_temp the fan is switched off.
+
+* 3: Fan speed mode
+  You ask for a specific fan speed by writing to the fan<n>_target file.
+
+Both of the automatic modes require that pwm1 corresponds to fan1, pwm2 to
+fan2 and pwm3 to fan3. Temperature mode also requires that temp1 corresponds
+to pwm1 and fan1, etc.

-Description
------------
-
-Fintek F718xx/F8000 Super I/O chips include complete hardware monitoring
-capabilities. They can monitor up to 9 voltages, 4 fans and 3 temperature
-sensors.
-
-These chips also have fan controlling features, using either DC or PWM, in
-three different modes (one manual, two automatic).
-
-The driver assumes that no more than one chip is present, which seems
-reasonable.
-
-
-Monitoring
-----------
-
-The Voltage, Fan and Temperature Monitoring uses the standard sysfs
-interface as documented in sysfs-interface, without any exceptions.
-
-
-Fan Control
------------
-
-Both PWM (pulse-width modulation) and DC fan speed control methods are
-supported. The right one to use depends on external circuitry on the
-motherboard, so the driver assumes that the BIOS set the method
-properly.
-
-Note that the lowest numbered temperature zone trip point corresponds to
-to the border between the highest and one but highest temperature zones, and
-vica versa. So the temperature zone trip points 1-4 (or 1-2) go from high temp
-to low temp! This is how things are implemented in the IC, and the driver
-mimics this.
-
-There are 2 modes to specify the speed of the fan, PWM duty cycle (or DC
-voltage) mode, where 0-100% duty cycle (0-100% of 12V) is specified. And RPM
-mode where the actual RPM of the fan (as measured) is controlled and the speed
-gets specified as 0-100% of the fan#_full_speed file.
-
-Since both modes work in a 0-100% (mapped to 0-255) scale, there isn't a
-whole lot of a difference when modifying fan control settings. The only
-important difference is that in RPM mode the 0-100% controls the fan speed
-between 0-100% of fan#_full_speed. It is assumed that if the BIOS programs
-RPM mode, it will also set fan#_full_speed properly, if it does not then
-fan control will not work properly, unless you set a sane fan#_full_speed
-value yourself.
-
-Switching between these modes requires re-initializing a whole bunch of
-registers, so the mode which the BIOS has set is kept. The mode is
-printed when loading the driver.
-
-Three different fan control modes are supported; the mode number is written
-to the pwm#_enable file. Note that not all modes are supported on all
-chips, and some modes may only be available in RPM / PWM mode.
-Writing an unsupported mode will result in an invalid parameter error.
-
-* 1: Manual mode
-  You ask for a specific PWM duty cycle / DC voltage or a specific % of
-  fan#_full_speed by writing to the pwm# file. This mode is only
-  available on the F71858FG / F8000 if the fan channel is in RPM mode.
-
-* 2: Normal auto mode
-  You can define a number of temperature/fan speed trip points, which % the
-  fan should run at at this temp and which temp a fan should follow using the
-  standard sysfs interface. The number and type of trip points is chip
-  depended, see which files are available in sysfs.
-  Fan/PWM channel 3 of the F8000 is always in this mode!
-
-* 3: Thermostat mode (Only available on the F8000 when in duty cycle mode)
-  The fan speed is regulated to keep the temp the fan is mapped to between
-  temp#_auto_point2_temp and temp#_auto_point3_temp.
-
-All of the automatic modes require that pwm1 corresponds to fan1, pwm2 to
-fan2 and pwm3 to fan3.

-Description
------------
-
-1) Processor TDP (Thermal design power)
-
-Given a fixed frequency and voltage, the power consumption of a
-processor varies based on the workload being executed. Derated power
-is the power consumed when running a specific application. Thermal
-design power (TDP) is an example of derated power.
-
-This driver permits reading of registers providing power information
-of AMD Family 15h and 16h processors via TDP algorithm.
-
-For AMD Family 15h and 16h processors the following power values can
-be calculated using different processor northbridge function
-registers:
-
-* BasePwrWatts: Specifies in watts the maximum amount of power
-  consumed by the processor for NB and logic external to the core.
-* ProcessorPwrWatts: Specifies in watts the maximum amount of power
-  the processor can support.
-* CurrPwrWatts: Specifies in watts the current amount of power being

-
-This driver provides ProcessorPwrWatts and CurrPwrWatts:
-* power1_crit (ProcessorPwrWatts)

-
-On multi-node processors the calculated value is for the entire

-
-Setting a period of 0 stops the fan; setting the period to 255 sets
-fan to maximum speed.
-
-The measured fan rotation speed returned via 'fan1_input' is derived
-from the measured speed pulse period by assuming again a 32kHz clock
-source and a 2 pulse-per-revolution fan.
-
-The 'alarms' file provides access to the two alarm bits provided by

-            of the programmed value for over 6 seconds 'fan1_alarm' is

-Description
------------
-
-IMPORTANT:
-
-For the revision 0x00 chip, the in0, in1, and in2  values (+5V, +3V,
-and +12V) CANNOT be read. This is a limitation of the chip, not the driver.
-
-This driver supports the Genesys Logic GL518SM chip. There are at least
-two revision of this chip, which we call revision 0x00 and 0x80. Revision
-0x80 chips support the reading of all voltages and revision 0x00 only
-for VIN3.
-
-The GL518SM implements one temperature sensor, two fan rotation speed
-sensors, and four voltage sensors. It can report alarms through the
-computer speakers.
-
-Temperatures are measured in degrees Celsius. An alarm goes off while the
-temperature is above the over temperature limit, and has not yet dropped
-below the hysteresis limit. The alarm always reflects the current
-situation. Measurements are guaranteed between -10 degrees and +110
-degrees, with a accuracy of +/-3 degrees.
-
-Rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. In
-case when you have selected to turn fan1 off, no fan1 alarm is triggered.
-
-Fan readings can be divided by a programmable divider (1, 2, 4 or 8) to
-give the readings more range or accuracy.  Not all RPM values can
-accurately be represented, so some rounding is done. With a divider
-of 2, the lowest representable value is around 1900 RPM.
-
-Voltage sensors (also known as VIN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. The VDD input
-measures voltages between 0.000 and 5.865 volt, with a resolution of 0.023
-volt. The other inputs measure voltages between 0.000 and 4.845 volt, with
-a resolution of 0.019 volt. Note that revision 0x00 chips do not support
-reading the current voltage of any input except for VIN3; limit setting and
-alarms work fine, though.
-
-When an alarm is triggered, you can be warned by a beeping signal through your
-computer speaker. It is possible to enable all beeping globally, or only the
-beeping for some alarms.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once (except for temperature alarms). This means that the
-cause for the alarm may already have disappeared! Note that in the current
-implementation, all hardware registers are read whenever any data is read
-(unless it is less than 1.5 seconds since the last update). This means that
-you can easily miss once-only alarms.
-
-The GL518SM only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

------------
-
-The HIH-6130 & HIH-6131 are humidity and temperature sensors in a SO8 package.
-The difference between the two devices is that the HIH-6131 has a condensation
-filter.
-
-The devices communicate with the I2C protocol. All sensors are set to the same
-I2C address 0x27 by default, so an entry with I2C_BOARD_INFO("hih6130", 0x27)
-can be used in the board setup code.

+Description
+-----------
+
+The HIH-6130 & HIH-6131 are humidity and temperature sensors in a SO8 package.
+The difference between the two devices is that the HIH-6131 has a condensation
+filter.
+
+The devices communicate with the I2C protocol. All sensors are set to the same
+I2C address 0x27 by default, so an entry with I2C_BOARD_INFO("hih6130", 0x27)
+can be used in the board setup code.
+
+Please see Documentation/i2c/instantiating-devices for details on how to
+instantiate I2C devices.

+The Linux Hardware Monitoring kernel API
+========================================
+
+Guenter Roeck
+
+Introduction
+------------
+
+This document describes the API that can be used by hardware monitoring
+drivers that want to use the hardware monitoring framework.
+
+This document does not describe what a hardware monitoring (hwmon) Driver or
+Device is. It also does not describe the API which can be used by user space
+to communicate with a hardware monitoring device. If you want to know this
+then please read the following file: Documentation/hwmon/sysfs-interface.rst.
+
+For additional guidelines on how to write and improve hwmon drivers, please
+also read Documentation/hwmon/submitting-patches.rst.
+
+The API
+-------
+Each hardware monitoring driver must #include <linux/hwmon.h> and, in most
+cases, <linux/hwmon-sysfs.h>. linux/hwmon.h declares the following
+register/unregister functions::
+
+  struct device *
+  hwmon_device_register_with_groups(struct device *dev, const char *name,
+				    void *drvdata,
+				    const struct attribute_group **groups);
+
+  struct device *
+  devm_hwmon_device_register_with_groups(struct device *dev,
+					 const char *name, void *drvdata,
+					 const struct attribute_group **groups);
+
+  struct device *
+  hwmon_device_register_with_info(struct device *dev,
+				  const char *name, void *drvdata,
+				  const struct hwmon_chip_info *info,
+				  const struct attribute_group **extra_groups);
+
+  struct device *
+  devm_hwmon_device_register_with_info(struct device *dev,
+				       const char *name,
+				       void *drvdata,
+				       const struct hwmon_chip_info *info,
+				       const struct attribute_group **extra_groups);
+
+  void hwmon_device_unregister(struct device *dev);
+
+  void devm_hwmon_device_unregister(struct device *dev);
+
+hwmon_device_register_with_groups registers a hardware monitoring device.
+The first parameter of this function is a pointer to the parent device.
+The name parameter is a pointer to the hwmon device name. The registration
+function wil create a name sysfs attribute pointing to this name.
+The drvdata parameter is the pointer to the local driver data.
+hwmon_device_register_with_groups will attach this pointer to the newly
+allocated hwmon device. The pointer can be retrieved by the driver using
+dev_get_drvdata() on the hwmon device pointer. The groups parameter is
+a pointer to a list of sysfs attribute groups. The list must be NULL terminated.
+hwmon_device_register_with_groups creates the hwmon device with name attribute
+as well as all sysfs attributes attached to the hwmon device.
+This function returns a pointer to the newly created hardware monitoring device
+or PTR_ERR for failure.
+
+devm_hwmon_device_register_with_groups is similar to
+hwmon_device_register_with_groups. However, it is device managed, meaning the
+hwmon device does not have to be removed explicitly by the removal function.
+
+hwmon_device_register_with_info is the most comprehensive and preferred means
+to register a hardware monitoring device. It creates the standard sysfs
+attributes in the hardware monitoring core, letting the driver focus on reading
+from and writing to the chip instead of having to bother with sysfs attributes.
+The parent device parameter cannot be NULL with non-NULL chip info. Its
+parameters are described in more detail below.
+
+devm_hwmon_device_register_with_info is similar to
+hwmon_device_register_with_info. However, it is device managed, meaning the
+hwmon device does not have to be removed explicitly by the removal function.
+
+hwmon_device_unregister deregisters a registered hardware monitoring device.
+The parameter of this function is the pointer to the registered hardware
+monitoring device structure. This function must be called from the driver
+remove function if the hardware monitoring device was registered with
+hwmon_device_register_with_groups or hwmon_device_register_with_info.
+
+devm_hwmon_device_unregister does not normally have to be called. It is only
+needed for error handling, and only needed if the driver probe fails after
+the call to devm_hwmon_device_register_with_groups or
+hwmon_device_register_with_info and if the automatic (device managed)
+removal would be too late.
+
+All supported hwmon device registration functions only accept valid device
+names. Device names including invalid characters (whitespace, '*', or '-')
+will be rejected. The 'name' parameter is mandatory.
+
+Using devm_hwmon_device_register_with_info()
+--------------------------------------------
+
+hwmon_device_register_with_info() registers a hardware monitoring device.
+The parameters to this function are
+
+=============================================== ===============================================
+`struct device *dev`				Pointer to parent device
+`const char *name`				Device name
+`void *drvdata`					Driver private data
+`const struct hwmon_chip_info *info`		Pointer to chip description.
+`const struct attribute_group **extra_groups` 	Null-terminated list of additional non-standard
+						sysfs attribute groups.
+=============================================== ===============================================
+
+This function returns a pointer to the created hardware monitoring device
+on success and a negative error code for failure.
+
+The hwmon_chip_info structure looks as follows::
+
+	struct hwmon_chip_info {
+		const struct hwmon_ops *ops;
+		const struct hwmon_channel_info **info;
+	};
+
+It contains the following fields:
+
+* ops:
+	Pointer to device operations.
+* info:
+	NULL-terminated list of device channel descriptors.
+
+The list of hwmon operations is defined as::
+
+  struct hwmon_ops {
+	umode_t (*is_visible)(const void *, enum hwmon_sensor_types type,
+			      u32 attr, int);
+	int (*read)(struct device *, enum hwmon_sensor_types type,
+		    u32 attr, int, long *);
+	int (*write)(struct device *, enum hwmon_sensor_types type,
+		     u32 attr, int, long);
+  };
+
+It defines the following operations.
+
+* is_visible:
+    Pointer to a function to return the file mode for each supported
+    attribute. This function is mandatory.
+
+* read:
+    Pointer to a function for reading a value from the chip. This function
+    is optional, but must be provided if any readable attributes exist.
+
+* write:
+    Pointer to a function for writing a value to the chip. This function is
+    optional, but must be provided if any writeable attributes exist.
+
+Each sensor channel is described with struct hwmon_channel_info, which is
+defined as follows::
+
+	struct hwmon_channel_info {
+		enum hwmon_sensor_types type;
+		u32 *config;
+	};
+
+It contains following fields:
+
+* type:
+    The hardware monitoring sensor type.
+
+    Supported sensor types are
+
+     ================== ==================================================
+     hwmon_chip		A virtual sensor type, used to describe attributes
+			which are not bound to a specific input or output
+     hwmon_temp		Temperature sensor
+     hwmon_in		Voltage sensor
+     hwmon_curr		Current sensor
+     hwmon_power		Power sensor
+     hwmon_energy	Energy sensor
+     hwmon_humidity	Humidity sensor
+     hwmon_fan		Fan speed sensor
+     hwmon_pwm		PWM control
+     ================== ==================================================
+
+* config:
+    Pointer to a 0-terminated list of configuration values for each
+    sensor of the given type. Each value is a combination of bit values
+    describing the attributes supposed by a single sensor.
+
+As an example, here is the complete description file for a LM75 compatible
+sensor chip. The chip has a single temperature sensor. The driver wants to
+register with the thermal subsystem (HWMON_C_REGISTER_TZ), and it supports
+the update_interval attribute (HWMON_C_UPDATE_INTERVAL). The chip supports
+reading the temperature (HWMON_T_INPUT), it has a maximum temperature
+register (HWMON_T_MAX) as well as a maximum temperature hysteresis register
+(HWMON_T_MAX_HYST)::
+
+	static const u32 lm75_chip_config[] = {
+		HWMON_C_REGISTER_TZ | HWMON_C_UPDATE_INTERVAL,
+		0
+	};
+
+	static const struct hwmon_channel_info lm75_chip = {
+		.type = hwmon_chip,
+		.config = lm75_chip_config,
+	};
+
+	static const u32 lm75_temp_config[] = {
+		HWMON_T_INPUT | HWMON_T_MAX | HWMON_T_MAX_HYST,
+		0
+	};
+
+	static const struct hwmon_channel_info lm75_temp = {
+		.type = hwmon_temp,
+		.config = lm75_temp_config,
+	};
+
+	static const struct hwmon_channel_info *lm75_info[] = {
+		&lm75_chip,
+		&lm75_temp,
+		NULL
+	};
+
+	The HWMON_CHANNEL_INFO() macro can and should be used when possible.
+	With this macro, the above example can be simplified to
+
+	static const struct hwmon_channel_info *lm75_info[] = {
+		HWMON_CHANNEL_INFO(chip,
+				HWMON_C_REGISTER_TZ | HWMON_C_UPDATE_INTERVAL),
+		HWMON_CHANNEL_INFO(temp,
+				HWMON_T_INPUT | HWMON_T_MAX | HWMON_T_MAX_HYST),
+		NULL
+	};
+
+	The remaining declarations are as follows.
+
+	static const struct hwmon_ops lm75_hwmon_ops = {
+		.is_visible = lm75_is_visible,
+		.read = lm75_read,
+		.write = lm75_write,
+	};
+
+	static const struct hwmon_chip_info lm75_chip_info = {
+		.ops = &lm75_hwmon_ops,
+		.info = lm75_info,
+	};
+
+A complete list of bit values indicating individual attribute support
+is defined in include/linux/hwmon.h. Definition prefixes are as follows.
+
+=============== =================================================
+HWMON_C_xxxx	Chip attributes, for use with hwmon_chip.
+HWMON_T_xxxx	Temperature attributes, for use with hwmon_temp.
+HWMON_I_xxxx	Voltage attributes, for use with hwmon_in.
+HWMON_C_xxxx	Current attributes, for use with hwmon_curr.
+		Notice the prefix overlap with chip attributes.
+HWMON_P_xxxx	Power attributes, for use with hwmon_power.
+HWMON_E_xxxx	Energy attributes, for use with hwmon_energy.
+HWMON_H_xxxx	Humidity attributes, for use with hwmon_humidity.
+HWMON_F_xxxx	Fan speed attributes, for use with hwmon_fan.
+HWMON_PWM_xxxx	PWM control attributes, for use with hwmon_pwm.
+=============== =================================================
+
+Driver callback functions
+-------------------------
+
+Each driver provides is_visible, read, and write functions. Parameters
+and return values for those functions are as follows::
+
+  umode_t is_visible_func(const void *data, enum hwmon_sensor_types type,
+			  u32 attr, int channel)
+
+Parameters:
+	data:
+		Pointer to device private data structure.
+	type:
+		The sensor type.
+	attr:
+		Attribute identifier associated with a specific attribute.
+		For example, the attribute value for HWMON_T_INPUT would be
+		hwmon_temp_input. For complete mappings of bit fields to
+		attribute values please see include/linux/hwmon.h.
+	channel:
+		The sensor channel number.
+
+Return value:
+	The file mode for this attribute. Typically, this will be 0 (the
+	attribute will not be created), S_IRUGO, or 'S_IRUGO | S_IWUSR'.
+
+::
+
+	int read_func(struct device *dev, enum hwmon_sensor_types type,
+		      u32 attr, int channel, long *val)
+
+Parameters:
+	dev:
+		Pointer to the hardware monitoring device.
+	type:
+		The sensor type.
+	attr:
+		Attribute identifier associated with a specific attribute.
+		For example, the attribute value for HWMON_T_INPUT would be
+		hwmon_temp_input. For complete mappings please see
+		include/linux/hwmon.h.
+	channel:
+		The sensor channel number.
+	val:
+		Pointer to attribute value.
+
+Return value:
+	0 on success, a negative error number otherwise.
+
+::
+
+	int write_func(struct device *dev, enum hwmon_sensor_types type,
+		       u32 attr, int channel, long val)
+
+Parameters:
+	dev:
+		Pointer to the hardware monitoring device.
+	type:
+		The sensor type.
+	attr:
+		Attribute identifier associated with a specific attribute.
+		For example, the attribute value for HWMON_T_INPUT would be
+		hwmon_temp_input. For complete mappings please see
+		include/linux/hwmon.h.
+	channel:
+		The sensor channel number.
+	val:
+		The value to write to the chip.
+
+Return value:
+	0 on success, a negative error number otherwise.
+
+
+Driver-provided sysfs attributes
+--------------------------------
+
+If the hardware monitoring device is registered with
+hwmon_device_register_with_info or devm_hwmon_device_register_with_info,
+it is most likely not necessary to provide sysfs attributes. Only additional
+non-standard sysfs attributes need to be provided when one of those registration
+functions is used.
+
+The header file linux/hwmon-sysfs.h provides a number of useful macros to
+declare and use hardware monitoring sysfs attributes.
+
+In many cases, you can use the exsting define DEVICE_ATTR or its variants
+DEVICE_ATTR_{RW,RO,WO} to declare such attributes. This is feasible if an
+attribute has no additional context. However, in many cases there will be
+additional information such as a sensor index which will need to be passed
+to the sysfs attribute handling function.
+
+SENSOR_DEVICE_ATTR and SENSOR_DEVICE_ATTR_2 can be used to define attributes
+which need such additional context information. SENSOR_DEVICE_ATTR requires
+one additional argument, SENSOR_DEVICE_ATTR_2 requires two.
+
+Simplified variants of SENSOR_DEVICE_ATTR and SENSOR_DEVICE_ATTR_2 are available
+and should be used if standard attribute permissions and function names are
+feasible. Standard permissions are 0644 for SENSOR_DEVICE_ATTR[_2]_RW,
+0444 for SENSOR_DEVICE_ATTR[_2]_RO, and 0200 for SENSOR_DEVICE_ATTR[_2]_WO.
+Standard functions, similar to DEVICE_ATTR_{RW,RO,WO}, have _show and _store
+appended to the provided function name.
+
+SENSOR_DEVICE_ATTR and its variants define a struct sensor_device_attribute
+variable. This structure has the following fields::
+
+	struct sensor_device_attribute {
+		struct device_attribute dev_attr;
+		int index;
+	};
+
+You can use to_sensor_dev_attr to get the pointer to this structure from the
+attribute read or write function. Its parameter is the device to which the
+attribute is attached.
+
+SENSOR_DEVICE_ATTR_2 and its variants define a struct sensor_device_attribute_2
+variable, which is defined as follows::
+
+	struct sensor_device_attribute_2 {
+		struct device_attribute dev_attr;
+		u8 index;
+		u8 nr;
+	};
+
+Use to_sensor_dev_attr_2 to get the pointer to this structure. Its parameter
+is the device to which the attribute is attached.

-Driver callback functions
--------------------------
-
-Each driver provides is_visible, read, and write functions. Parameters
-and return values for those functions are as follows.
-
-umode_t is_visible_func(const void *data, enum hwmon_sensor_types type,
-			u32 attr, int channel)
-
-Parameters:
-	data:	Pointer to device private data structure.
-	type:	The sensor type.
-	attr:	Attribute identifier associated with a specific attribute.
-		For example, the attribute value for HWMON_T_INPUT would be
-		hwmon_temp_input. For complete mappings of bit fields to
-		attribute values please see include/linux/hwmon.h.
-	channel:The sensor channel number.
-
-Return value:
-	The file mode for this attribute. Typically, this will be 0 (the
-	attribute will not be created), S_IRUGO, or 'S_IRUGO | S_IWUSR'.
-
-int read_func(struct device *dev, enum hwmon_sensor_types type,
-	      u32 attr, int channel, long *val)
-
-Parameters:
-	dev:	Pointer to the hardware monitoring device.
-	type:	The sensor type.
-	attr:	Attribute identifier associated with a specific attribute.
-		For example, the attribute value for HWMON_T_INPUT would be
-		hwmon_temp_input. For complete mappings please see
-		include/linux/hwmon.h.
-	channel:The sensor channel number.
-	val:	Pointer to attribute value.
-
-Return value:
-	0 on success, a negative error number otherwise.
-
-int write_func(struct device *dev, enum hwmon_sensor_types type,
-	       u32 attr, int channel, long val)
-
-Parameters:
-	dev:	Pointer to the hardware monitoring device.
-	type:	The sensor type.
-	attr:	Attribute identifier associated with a specific attribute.
-		For example, the attribute value for HWMON_T_INPUT would be
-		hwmon_temp_input. For complete mappings please see
-		include/linux/hwmon.h.
-	channel:The sensor channel number.
-	val:	The value to write to the chip.
-
-Return value:
-	0 on success, a negative error number otherwise.
-
-
-Driver-provided sysfs attributes
---------------------------------
-
-If the hardware monitoring device is registered with
-hwmon_device_register_with_info or devm_hwmon_device_register_with_info,
-it is most likely not necessary to provide sysfs attributes. Only additional
-non-standard sysfs attributes need to be provided when one of those registration
-functions is used.
-
-The header file linux/hwmon-sysfs.h provides a number of useful macros to
-declare and use hardware monitoring sysfs attributes.
-
-In many cases, you can use the exsting define DEVICE_ATTR or its variants
-DEVICE_ATTR_{RW,RO,WO} to declare such attributes. This is feasible if an
-attribute has no additional context. However, in many cases there will be
-additional information such as a sensor index which will need to be passed
-to the sysfs attribute handling function.
-
-SENSOR_DEVICE_ATTR and SENSOR_DEVICE_ATTR_2 can be used to define attributes
-which need such additional context information. SENSOR_DEVICE_ATTR requires
-one additional argument, SENSOR_DEVICE_ATTR_2 requires two.
-
-Simplified variants of SENSOR_DEVICE_ATTR and SENSOR_DEVICE_ATTR_2 are available
-and should be used if standard attribute permissions and function names are
-feasible. Standard permissions are 0644 for SENSOR_DEVICE_ATTR[_2]_RW,
-0444 for SENSOR_DEVICE_ATTR[_2]_RO, and 0200 for SENSOR_DEVICE_ATTR[_2]_WO.
-Standard functions, similar to DEVICE_ATTR_{RW,RO,WO}, have _show and _store
-appended to the provided function name.
-
-SENSOR_DEVICE_ATTR and its variants define a struct sensor_device_attribute
-variable. This structure has the following fields.
-
-struct sensor_device_attribute {
-	struct device_attribute dev_attr;
-	int index;
-};
-
-You can use to_sensor_dev_attr to get the pointer to this structure from the
-attribute read or write function. Its parameter is the device to which the
-attribute is attached.
-
-SENSOR_DEVICE_ATTR_2 and its variants define a struct sensor_device_attribute_2
-variable, which is defined as follows.
-
-struct sensor_device_attribute_2 {
-	struct device_attribute dev_attr;
-	u8 index;
-	u8 nr;
-};
-
-Use to_sensor_dev_attr_2 to get the pointer to this structure. Its parameter
-is the device to which the attribute is attached.

-Kernel driver ibmaem
-======================
-
-This driver talks to the IBM Systems Director Active Energy Manager, known
-henceforth as AEM.
-
-Supported systems:
-  * Any recent IBM System X server with AEM support.
-    This includes the x3350, x3550, x3650, x3655, x3755, x3850 M2,
-    x3950 M2, and certain HC10/HS2x/LS2x/QS2x blades.  The IPMI host interface
-    driver ("ipmi-si") needs to be loaded for this driver to do anything.
-    Prefix: 'ibmaem'
-    Datasheet: Not available
-
-Author: Darrick J. Wong
-
-Description
------------
-
-This driver implements sensor reading support for the energy and power meters
-available on various IBM System X hardware through the BMC.  All sensor banks
-will be exported as platform devices; this driver can talk to both v1 and v2
-interfaces.  This driver is completely separate from the older ibmpex driver.
-
-The v1 AEM interface has a simple set of features to monitor energy use.  There
-is a register that displays an estimate of raw energy consumption since the
-last BMC reset, and a power sensor that returns average power use over a
-configurable interval.
-
-The v2 AEM interface is a bit more sophisticated, being able to present a wider
-range of energy and power use registers, the power cap as set by the AEM
-software, and temperature sensors.
-
-Special Features
-----------------
-
-The "power_cap" value displays the current system power cap, as set by the AEM
-software.  Setting the power cap from the host is not currently supported.

-Author: Neelesh Gupta
-
-Description
------------
-
-This driver implements reading the platform sensors data like temperature/fan/
-voltage/power for 'POWERNV' platform.
-
-The driver uses the platform device infrastructure. It probes the device tree
-for sensor devices during the __init phase and registers them with the 'hwmon'.
-'hwmon' populates the 'sysfs' tree having attribute files, each for a given
-sensor type and its attribute data.
-
-All the nodes in the DT appear under "/ibm,opal/sensors" and each valid node in
-the DT maps to an attribute file in 'sysfs'. The node exports unique 'sensor-id'
-which the driver uses to make an OPAL call to the firmware.

-Description
------------
-
-The TI / Burr-Brown INA209 monitors voltage, current, and power on the high side
-of a D.C. power supply. It can perform measurements and calculations in the
-background to supply readings at any time. It includes a programmable
-calibration multiplier to scale the displayed current and power values.
-
-
-Sysfs entries
--------------
-
-The INA209 chip is highly configurable both via hardwiring and via
-the I2C bus. See the datasheet for details.
-
-This tries to expose most monitoring features of the hardware via
-sysfs. It does not support every feature of this chip.

-
-General Remarks
----------------
-
-The power and current registers in this chip require that the calibration
-register is programmed correctly before they are used. Normally this is expected
-to be done in the BIOS. In the absence of BIOS programming, the shunt resistor
-voltage can be provided using platform data. The driver uses platform data from
-the ina2xx driver for this purpose. If calibration register data is not provided
-via platform data, the driver checks if the calibration register has been
-programmed (ie has a value not equal to zero). If so, this value is retained.
-Otherwise, a default value reflecting a shunt resistor value of 10 mOhm is
-programmed into the calibration register.
-
-
-Output Pins
------------
-
-Output pin programming is a board feature which depends on the BIOS. It is
-outside the scope of a hardware monitoring driver to enable or disable output
-pins.

+Description
+-----------
+
+The TI / Burr-Brown INA209 monitors voltage, current, and power on the high side
+of a D.C. power supply. It can perform measurements and calculations in the
+background to supply readings at any time. It includes a programmable
+calibration multiplier to scale the displayed current and power values.
+
+
+Sysfs entries
+-------------
+
+The INA209 chip is highly configurable both via hardwiring and via
+the I2C bus. See the datasheet for details.
+
+This tries to expose most monitoring features of the hardware via
+sysfs. It does not support every feature of this chip.

+
+General Remarks
+---------------
+
+The power and current registers in this chip require that the calibration
+register is programmed correctly before they are used. Normally this is expected
+to be done in the BIOS. In the absence of BIOS programming, the shunt resistor
+voltage can be provided using platform data. The driver uses platform data from
+the ina2xx driver for this purpose. If calibration register data is not provided
+via platform data, the driver checks if the calibration register has been
+programmed (ie has a value not equal to zero). If so, this value is retained.
+Otherwise, a default value reflecting a shunt resistor value of 10 mOhm is
+programmed into the calibration register.
+
+
+Output Pins
+-----------
+
+Output pin programming is a board feature which depends on the BIOS. It is
+outside the scope of a hardware monitoring driver to enable or disable output
+pins.

-Description
------------
-
-The INA219 is a high-side current shunt and power monitor with an I2C
-interface. The INA219 monitors both shunt drop and supply voltage, with
-programmable conversion times and filtering.
-
-The INA220 is a high or low side current shunt and power monitor with an I2C
-interface. The INA220 monitors both shunt drop and supply voltage.
-
-The INA226 is a current shunt and power monitor with an I2C interface.
-The INA226 monitors both a shunt voltage drop and bus supply voltage.
-
-INA230 and INA231 are high or low side current shunt and power monitors
-with an I2C interface. The chips monitor both a shunt voltage drop and
-bus supply voltage.
-
-The shunt value in micro-ohms can be set via platform data or device tree at
-compile-time or via the shunt_resistor attribute in sysfs at run-time. Please
-refer to the Documentation/devicetree/bindings/hwmon/ina2xx.txt for bindings
-if the device tree is used.
-
-Additionally ina226 supports update_interval attribute as described in
-Documentation/hwmon/sysfs-interface. Internally the interval is the sum of
-bus and shunt voltage conversion times multiplied by the averaging rate. We
-don't touch the conversion times and only modify the number of averages. The
-lower limit of the update_interval is 2 ms, the upper limit is 2253 ms.
-The actual programmed interval may vary from the desired value.

-Module Parameters
------------------
-
-* update_vbat: int
-
-  0 if vbat should report power on value, 1 if vbat should be updated after
-  each read. Default is 0. On some boards the battery voltage is provided
-  by either the battery or the onboard power supply. Only the first reading
-  at power on will be the actual battery voltage (which the chip does
-  automatically). On other boards the battery voltage is always fed to
-  the chip so can be read at any time. Excessive reading may decrease
-  battery life but no information is given in the datasheet.
-
-* fix_pwm_polarity int
-
-  Force PWM polarity to active high (DANGEROUS). Some chips are
-  misconfigured by BIOS - PWM values would be inverted. This option tries
-  to fix this. Please contact your BIOS manufacturer and ask him for fix.
-
-
-Hardware Interfaces
--------------------
-
-All the chips supported by this driver are LPC Super-I/O chips, accessed
-through the LPC bus (ISA-like I/O ports). The IT8712F additionally has an
-SMBus interface to the hardware monitoring functions. This driver no
-longer supports this interface though, as it is slower and less reliable
-than the ISA access, and was only available on a small number of
-motherboard models.
-
-
-Description
------------
-
-This driver implements support for the IT8603E, IT8620E, IT8623E, IT8628E,
-IT8705F, IT8712F, IT8716F, IT8718F, IT8720F, IT8721F, IT8726F, IT8728F, IT8732F,
-IT8758E, IT8771E, IT8772E, IT8781F, IT8782F, IT8783E/F, IT8786E, IT8790E, and
-SiS950 chips.
-
-These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
-joysticks and other miscellaneous stuff. For hardware monitoring, they
-include an 'environment controller' with 3 temperature sensors, 3 fan
-rotation speed sensors, 8 voltage sensors, associated alarms, and chassis
-intrusion detection.
-
-The IT8712F and IT8716F additionally feature VID inputs, used to report
-the Vcore voltage of the processor. The early IT8712F have 5 VID pins,
-the IT8716F and late IT8712F have 6. They are shared with other functions
-though, so the functionality may not be available on a given system.
-
-The IT8718F and IT8720F also features VID inputs (up to 8 pins) but the value
-is stored in the Super-I/O configuration space. Due to technical limitations,
-this value can currently only be read once at initialization time, so
-the driver won't notice and report changes in the VID value. The two
-upper VID bits share their pins with voltage inputs (in5 and in6) so you
-can't have both on a given board.
-
-The IT8716F, IT8718F, IT8720F, IT8721F/IT8758E and later IT8712F revisions
-have support for 2 additional fans. The additional fans are supported by the
-driver.
-
-The IT8716F, IT8718F, IT8720F, IT8721F/IT8758E, IT8732F, IT8781F, IT8782F,
-IT8783E/F, and late IT8712F and IT8705F also have optional 16-bit tachometer
-counters for fans 1 to 3. This is better (no more fan clock divider mess) but
-not compatible with the older chips and revisions. The 16-bit tachometer mode
-is enabled by the driver when one of the above chips is detected.
-
-The IT8726F is just bit enhanced IT8716F with additional hardware
-for AMD power sequencing. Therefore the chip will appear as IT8716F
-to userspace applications.
-
-The IT8728F, IT8771E, and IT8772E are considered compatible with the IT8721F,
-until a datasheet becomes available (hopefully.)
-
-The IT8603E/IT8623E is a custom design, hardware monitoring part is similar to
-IT8728F. It only supports 3 fans, 16-bit fan mode, and the full speed mode
-of the fan is not supported (value 0 of pwmX_enable).
-
-The IT8620E and IT8628E are custom designs, hardware monitoring part is similar
-to IT8728F. It only supports 16-bit fan mode. Both chips support up to 6 fans.
-
-The IT8790E supports up to 3 fans. 16-bit fan mode is always enabled.
-
-The IT8732F supports a closed-loop mode for fan control, but this is not
-currently implemented by the driver.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. When
-16-bit tachometer counters aren't used, fan readings can be divided by
-a programmable divider (1, 2, 4 or 8) to give the readings more range or
-accuracy. With a divider of 2, the lowest representable value is around
-2600 RPM. Not all RPM values can accurately be represented, so some rounding
-is done.
-
-Voltage sensors (also known as IN sensors) report their values in volts. An
-alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. On most chips, all
-voltage inputs can measure voltages between 0 and 4.08 volts, with a resolution
-of 0.016 volt.  IT8603E, IT8721F/IT8758E and IT8728F can measure between 0 and
-3.06 volts, with a resolution of 0.012 volt.  IT8732F can measure between 0 and
-2.8 volts with a resolution of 0.0109 volt.  The battery voltage in8 does not
-have limit registers.
-
-On the IT8603E, IT8620E, IT8628E, IT8721F/IT8758E, IT8732F, IT8781F, IT8782F,
-and IT8783E/F, some voltage inputs are internal and scaled inside the chip:
-* in3 (optional)
-* in7 (optional for IT8781F, IT8782F, and IT8783E/F)
-* in8 (always)
-* in9 (relevant for IT8603E only)
-The driver handles this transparently so user-space doesn't have to care.
-
-The VID lines (IT8712F/IT8716F/IT8718F/IT8720F) encode the core voltage value:
-the voltage level your processor should work with. This is hardcoded by
-the mainboard and/or processor itself. It is a value in volts.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 1.5
-seconds since the last update). This means that you can easily miss
-once-only alarms.
-
-Out-of-limit readings can also result in beeping, if the chip is properly
-wired and configured. Beeping can be enabled or disabled per sensor type
-(temperatures, voltages and fans.)
-
-The IT87xx only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-To change sensor N to a thermistor, 'echo 4 > tempN_type' where N is 1, 2,
-or 3. To change sensor N to a thermal diode, 'echo 3 > tempN_type'.
-Give 0 for unused sensor. Any other value is invalid. To configure this at
-startup, consult lm_sensors's /etc/sensors.conf. (4 = thermistor;
-3 = thermal diode)
-
-
-Fan speed control
------------------
-
-The fan speed control features are limited to manual PWM mode. Automatic
-"Smart Guardian" mode control handling is only implemented for older chips
-(see below.) However if you want to go for "manual mode" just write 1 to
-pwmN_enable.
-
-If you are only able to control the fan speed with very small PWM values,
-try lowering the PWM base frequency (pwm1_freq). Depending on the fan,
-it may give you a somewhat greater control range. The same frequency is
-used to drive all fan outputs, which is why pwm2_freq and pwm3_freq are
-read-only.
-
-
-Automatic fan speed control (old interface)
--------------------------------------------
-
-The driver supports the old interface to automatic fan speed control
-which is implemented by IT8705F chips up to revision F and IT8712F
-chips up to revision G.
-
-This interface implements 4 temperature vs. PWM output trip points.
-The PWM output of trip point 4 is always the maximum value (fan running
-at full speed) while the PWM output of the other 3 trip points can be
-freely chosen. The temperature of all 4 trip points can be freely chosen.
-Additionally, trip point 1 has an hysteresis temperature attached, to
-prevent fast switching between fan on and off.
-
-The chip automatically computes the PWM output value based on the input
-temperature, based on this simple rule: if the temperature value is
-between trip point N and trip point N+1 then the PWM output value is
-the one of trip point N. The automatic control mode is less flexible
-than the manual control mode, but it reacts faster, is more robust and
-doesn't use CPU cycles.
-
-Trip points must be set properly before switching to automatic fan speed
-control mode. The driver will perform basic integrity checks before
-actually switching to automatic control mode.
-
-
-Temperature offset attributes
------------------------------
-
-The driver supports temp[1-3]_offset sysfs attributes to adjust the reported
-temperature for thermal diodes or diode-connected thermal transistors.
-If a temperature sensor is configured for thermistors, the attribute values

+Module Parameters
+-----------------
+
+* update_vbat: int
+    0 if vbat should report power on value, 1 if vbat should be updated after
+    each read. Default is 0. On some boards the battery voltage is provided
+    by either the battery or the onboard power supply. Only the first reading
+    at power on will be the actual battery voltage (which the chip does
+    automatically). On other boards the battery voltage is always fed to
+    the chip so can be read at any time. Excessive reading may decrease
+    battery life but no information is given in the datasheet.
+
+* fix_pwm_polarity int
+    Force PWM polarity to active high (DANGEROUS). Some chips are
+    misconfigured by BIOS - PWM values would be inverted. This option tries
+    to fix this. Please contact your BIOS manufacturer and ask him for fix.
+
+
+Hardware Interfaces
+-------------------
+
+All the chips supported by this driver are LPC Super-I/O chips, accessed
+through the LPC bus (ISA-like I/O ports). The IT8712F additionally has an
+SMBus interface to the hardware monitoring functions. This driver no
+longer supports this interface though, as it is slower and less reliable
+than the ISA access, and was only available on a small number of
+motherboard models.
+
+
+Description
+-----------
+
+This driver implements support for the IT8603E, IT8620E, IT8623E, IT8628E,
+IT8705F, IT8712F, IT8716F, IT8718F, IT8720F, IT8721F, IT8726F, IT8728F, IT8732F,
+IT8758E, IT8771E, IT8772E, IT8781F, IT8782F, IT8783E/F, IT8786E, IT8790E, and
+SiS950 chips.
+
+These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
+joysticks and other miscellaneous stuff. For hardware monitoring, they
+include an 'environment controller' with 3 temperature sensors, 3 fan
+rotation speed sensors, 8 voltage sensors, associated alarms, and chassis
+intrusion detection.
+
+The IT8712F and IT8716F additionally feature VID inputs, used to report
+the Vcore voltage of the processor. The early IT8712F have 5 VID pins,
+the IT8716F and late IT8712F have 6. They are shared with other functions
+though, so the functionality may not be available on a given system.
+
+The IT8718F and IT8720F also features VID inputs (up to 8 pins) but the value
+is stored in the Super-I/O configuration space. Due to technical limitations,
+this value can currently only be read once at initialization time, so
+the driver won't notice and report changes in the VID value. The two
+upper VID bits share their pins with voltage inputs (in5 and in6) so you
+can't have both on a given board.
+
+The IT8716F, IT8718F, IT8720F, IT8721F/IT8758E and later IT8712F revisions
+have support for 2 additional fans. The additional fans are supported by the
+driver.
+
+The IT8716F, IT8718F, IT8720F, IT8721F/IT8758E, IT8732F, IT8781F, IT8782F,
+IT8783E/F, and late IT8712F and IT8705F also have optional 16-bit tachometer
+counters for fans 1 to 3. This is better (no more fan clock divider mess) but
+not compatible with the older chips and revisions. The 16-bit tachometer mode
+is enabled by the driver when one of the above chips is detected.
+
+The IT8726F is just bit enhanced IT8716F with additional hardware
+for AMD power sequencing. Therefore the chip will appear as IT8716F
+to userspace applications.
+
+The IT8728F, IT8771E, and IT8772E are considered compatible with the IT8721F,
+until a datasheet becomes available (hopefully.)
+
+The IT8603E/IT8623E is a custom design, hardware monitoring part is similar to
+IT8728F. It only supports 3 fans, 16-bit fan mode, and the full speed mode
+of the fan is not supported (value 0 of pwmX_enable).
+
+The IT8620E and IT8628E are custom designs, hardware monitoring part is similar
+to IT8728F. It only supports 16-bit fan mode. Both chips support up to 6 fans.
+
+The IT8790E supports up to 3 fans. 16-bit fan mode is always enabled.
+
+The IT8732F supports a closed-loop mode for fan control, but this is not
+currently implemented by the driver.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. When
+16-bit tachometer counters aren't used, fan readings can be divided by
+a programmable divider (1, 2, 4 or 8) to give the readings more range or
+accuracy. With a divider of 2, the lowest representable value is around
+2600 RPM. Not all RPM values can accurately be represented, so some rounding
+is done.
+
+Voltage sensors (also known as IN sensors) report their values in volts. An
+alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. On most chips, all
+voltage inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.  IT8603E, IT8721F/IT8758E and IT8728F can measure between 0 and
+3.06 volts, with a resolution of 0.012 volt.  IT8732F can measure between 0 and
+2.8 volts with a resolution of 0.0109 volt.  The battery voltage in8 does not
+have limit registers.
+
+On the IT8603E, IT8620E, IT8628E, IT8721F/IT8758E, IT8732F, IT8781F, IT8782F,
+and IT8783E/F, some voltage inputs are internal and scaled inside the chip:
+* in3 (optional)
+* in7 (optional for IT8781F, IT8782F, and IT8783E/F)
+* in8 (always)
+* in9 (relevant for IT8603E only)
+The driver handles this transparently so user-space doesn't have to care.
+
+The VID lines (IT8712F/IT8716F/IT8718F/IT8720F) encode the core voltage value:
+the voltage level your processor should work with. This is hardcoded by
+the mainboard and/or processor itself. It is a value in volts.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 1.5
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+
+Out-of-limit readings can also result in beeping, if the chip is properly
+wired and configured. Beeping can be enabled or disabled per sensor type
+(temperatures, voltages and fans.)
+
+The IT87xx only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+To change sensor N to a thermistor, 'echo 4 > tempN_type' where N is 1, 2,
+or 3. To change sensor N to a thermal diode, 'echo 3 > tempN_type'.
+Give 0 for unused sensor. Any other value is invalid. To configure this at
+startup, consult lm_sensors's /etc/sensors.conf. (4 = thermistor;
+3 = thermal diode)
+
+
+Fan speed control
+-----------------
+
+The fan speed control features are limited to manual PWM mode. Automatic
+"Smart Guardian" mode control handling is only implemented for older chips
+(see below.) However if you want to go for "manual mode" just write 1 to
+pwmN_enable.
+
+If you are only able to control the fan speed with very small PWM values,
+try lowering the PWM base frequency (pwm1_freq). Depending on the fan,
+it may give you a somewhat greater control range. The same frequency is
+used to drive all fan outputs, which is why pwm2_freq and pwm3_freq are
+read-only.
+
+
+Automatic fan speed control (old interface)
+-------------------------------------------
+
+The driver supports the old interface to automatic fan speed control
+which is implemented by IT8705F chips up to revision F and IT8712F
+chips up to revision G.
+
+This interface implements 4 temperature vs. PWM output trip points.
+The PWM output of trip point 4 is always the maximum value (fan running
+at full speed) while the PWM output of the other 3 trip points can be
+freely chosen. The temperature of all 4 trip points can be freely chosen.
+Additionally, trip point 1 has an hysteresis temperature attached, to
+prevent fast switching between fan on and off.
+
+The chip automatically computes the PWM output value based on the input
+temperature, based on this simple rule: if the temperature value is
+between trip point N and trip point N+1 then the PWM output value is
+the one of trip point N. The automatic control mode is less flexible
+than the manual control mode, but it reacts faster, is more robust and
+doesn't use CPU cycles.
+
+Trip points must be set properly before switching to automatic fan speed
+control mode. The driver will perform basic integrity checks before
+actually switching to automatic control mode.
+
+
+Temperature offset attributes
+-----------------------------
+
+The driver supports temp[1-3]_offset sysfs attributes to adjust the reported
+temperature for thermal diodes or diode-connected thermal transistors.
+If a temperature sensor is configured for thermistors, the attribute values
+are ignored. If the thermal sensor type is Intel PECI, the temperature offset
+must be programmed to the critical CPU temperature.

-Description
------------
-
-This driver implements support for JEDEC JC 42.4 compliant temperature sensors,
-which are used on many DDR3 memory modules for mobile devices and servers. Some
-systems use the sensor to prevent memory overheating by automatically throttling
-the memory controller.
-
-The driver auto-detects the chips listed above, but can be manually instantiated
-to support other JC 42.4 compliant chips.
-
-Example: the following will load the driver for a generic JC 42.4 compliant
-temperature sensor at address 0x18 on I2C bus #1:
-
-# modprobe jc42
-# echo jc42 0x18 > /sys/bus/i2c/devices/i2c-1/new_device
-
-A JC 42.4 compliant chip supports a single temperature sensor. Minimum, maximum,
-and critical temperature can be configured. There are alarms for high, low,
-and critical thresholds.
-
-There is also an hysteresis to control the thresholds for resetting alarms.
-Per JC 42.4 specification, the hysteresis threshold can be configured to 0, 1.5,
-3.0, and 6.0 degrees C. Configured hysteresis values will be rounded to those
-limits. The chip supports only a single register to configure the hysteresis,
-which applies to all limits. This register can be written by writing into
-temp1_crit_hyst. Other hysteresis attributes are read-only.
-
-If the BIOS has configured the sensor for automatic temperature management, it
-is likely that it has locked the registers, i.e., that the temperature limits
-cannot be changed.

+the memory controller.
+
+The driver auto-detects the chips listed above, but can be manually instantiated
+to support other JC 42.4 compliant chips.
+
+Example: the following will load the driver for a generic JC 42.4 compliant
+temperature sensor at address 0x18 on I2C bus #1::
+
+	# modprobe jc42
+	# echo jc42 0x18 > /sys/bus/i2c/devices/i2c-1/new_device
+
+A JC 42.4 compliant chip supports a single temperature sensor. Minimum, maximum,
+and critical temperature can be configured. There are alarms for high, low,
+and critical thresholds.
+
+There is also an hysteresis to control the thresholds for resetting alarms.
+Per JC 42.4 specification, the hysteresis threshold can be configured to 0, 1.5,
+3.0, and 6.0 degrees C. Configured hysteresis values will be rounded to those
+limits. The chip supports only a single register to configure the hysteresis,
+which applies to all limits. This register can be written by writing into
+temp1_crit_hyst. Other hysteresis attributes are read-only.
+
+If the BIOS has configured the sensor for automatic temperature management, it
+is likely that it has locked the registers, i.e., that the temperature limits
+cannot be changed.

-Description
------------
-
-This driver permits reading of the internal temperature sensor of AMD
-Family 10h/11h/12h/14h/15h/16h processors.
-
-All these processors have a sensor, but on those for Socket F or AM2+,
-the sensor may return inconsistent values (erratum 319).  The driver
-will refuse to load on these revisions unless you specify the "force=1"
-module parameter.
-
-Due to technical reasons, the driver can detect only the mainboard's
-socket type, not the processor's actual capabilities.  Therefore, if you
-are using an AM3 processor on an AM2+ mainboard, you can safely use the
-"force=1" parameter.
-
-There is one temperature measurement value, available as temp1_input in
-sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree.
-Please note that it is defined as a relative value; to quote the AMD manual:
-
-  Tctl is the processor temperature control value, used by the platform to
-  control cooling systems. Tctl is a non-physical temperature on an
-  arbitrary scale measured in degrees. It does _not_ represent an actual
-  physical temperature like die or case temperature. Instead, it specifies
-  the processor temperature relative to the point at which the system must
-  supply the maximum cooling for the processor's specified maximum case
-  temperature and maximum thermal power dissipation.
-
-The maximum value for Tctl is available in the file temp1_max.
-
-If the BIOS has enabled hardware temperature control, the threshold at
-which the processor will throttle itself to avoid damage is available in
-temp1_crit and temp1_crit_hyst.

-Description
------------
-
-This driver permits reading temperature sensor(s) embedded inside AMD K8
-family CPUs (Athlon64/FX, Opteron). Official documentation says that it works
-from revision F of K8 core, but in fact it seems to be implemented for all
-revisions of K8 except the first two revisions (SH-B0 and SH-B3).
-
-Please note that you will need at least lm-sensors 2.10.1 for proper userspace
-support.
-
-There can be up to four temperature sensors inside single CPU. The driver
-will auto-detect the sensors and will display only temperatures from
-implemented sensors.
-
-Mapping of /sys files is as follows:
-
-temp1_input - temperature of Core 0 and "place" 0
-temp2_input - temperature of Core 0 and "place" 1
-temp3_input - temperature of Core 1 and "place" 0
-temp4_input - temperature of Core 1 and "place" 1
-
-Temperatures are measured in degrees Celsius and measurement resolution is
-1 degree C. It is expected that future CPU will have better resolution. The
-temperature is updated once a second. Valid temperatures are from -49 to
-206 degrees C.
-
-Temperature known as TCaseMax was specified for processors up to revision E.
-This temperature is defined as temperature between heat-spreader and CPU
-case, so the internal CPU temperature supplied by this driver can be higher.
-There is no easy way how to measure the temperature which will correlate
-with TCaseMax temperature.
-
-For newer revisions of CPU (rev F, socket AM2) there is a mathematically
-computed temperature called TControl, which must be lower than TControlMax.
-
-The relationship is following:
-
-temp1_input - TjOffset*2 < TControlMax,
-
-TjOffset is not yet exported by the driver, TControlMax is usually
-70 degrees C. The rule of the thumb -> CPU temperature should not cross
-60 degrees C too much.

-
-All Lineage CPL power entry modules have a built-in I2C bus master selector

-Description
------------
-
-The LM63 is a digital temperature sensor with integrated fan monitoring
-and control.
-
-The LM63 is basically an LM86 with fan speed monitoring and control
-capabilities added. It misses some of the LM86 features though:
- - No low limit for local temperature.
- - No critical limit for local temperature.
- - Critical limit for remote temperature can be changed only once. We
-   will consider that the critical limit is read-only.
-
-The datasheet isn't very clear about what the tachometer reading is.
-
-An explanation from National Semiconductor: The two lower bits of the read
-value have to be masked out. The value is still 16 bit in width.
-
-All temperature values are given in degrees Celsius. Resolution is 1.0
-degree for the local temperature, 0.125 degree for the remote temperature.
-
-The fan speed is measured using a tachometer. Contrary to most chips which
-store the value in an 8-bit register and have a selectable clock divider
-to make sure that the result will fit in the register, the LM63 uses 16-bit
-value for measuring the speed of the fan. It can measure fan speeds down to
-83 RPM, at least in theory.
-
-Note that the pin used for fan monitoring is shared with an alert out
-function. Depending on how the board designer wanted to use the chip, fan
-speed monitoring will or will not be possible. The proper chip configuration
-is left to the BIOS, and the driver will blindly trust it. Only the original
-LM63 suffers from this limitation, the LM64 and LM96163 have separate pins
-for fan monitoring and alert out. On the LM64, monitoring is always enabled;
-on the LM96163 it can be disabled.
-
-A PWM output can be used to control the speed of the fan. The LM63 has two
-PWM modes: manual and automatic. Automatic mode is not fully implemented yet
-(you cannot define your custom PWM/temperature curve), and mode change isn't
-supported either.
-
-The lm63 driver will not update its values more frequently than configured with
-the update_interval sysfs attribute; reading them more often will do no harm,
-but will return 'old' values. Values in the automatic fan control lookup table
-(attributes pwm1_auto_*) have their own independent lifetime of 5 seconds.
-
-The LM64 is effectively an LM63 with GPIO lines. The driver does not
-support these GPIO lines at present.
-
-The LM96163 is an enhanced version of LM63 with improved temperature accuracy
-and better PWM resolution. For LM96163, the external temperature sensor type is
-configurable as CPU embedded diode(1) or 3904 transistor(2).

-    Addresses scanned: I2C 0x48, 0x49, 0x4a, 0x4c, 0x4d, and 0x4e

-
-Author: Guillaume Ligneul <guillaume.ligneul@gmail.com>
-Documentation: Chris Verges <kg4ysn@gmail.com>
-
-
-Description
------------
-
-The LM73 is a digital temperature sensor.  All temperature values are
-given in degrees Celsius.
-
-Measurement Resolution Support
-------------------------------
-
-The LM73 supports four resolutions, defined in terms of degrees C per
-LSB: 0.25, 0.125, 0.0625, and 0.3125.  Changing the resolution mode
-affects the conversion time of the LM73's analog-to-digital converter.
-From userspace, the desired resolution can be specified as a function of
-conversion time via the 'update_interval' sysfs attribute for the
-device.  This attribute will normalize ranges of input values to the
-maximum times defined for the resolution in the datasheet.
-
-    Resolution    Conv. Time    Input Range
-    (C/LSB)       (msec)        (msec)
-    --------------------------------------
-    0.25          14             0..14
-    0.125         28            15..28
-    0.0625        56            29..56
-    0.03125       112           57..infinity
-    --------------------------------------
-
-The following examples show how the 'update_interval' attribute can be
-used to change the conversion time:
-
-    $ echo 0 > update_interval
-    $ cat update_interval
-    14
-    $ cat temp1_input
-    24250
-
-    $ echo 22 > update_interval
-    $ cat update_interval
-    28
-    $ cat temp1_input
-    24125
-
-    $ echo 56 > update_interval
-    $ cat update_interval
-    56
-    $ cat temp1_input
-    24062
-
-    $ echo 85 > update_interval
-    $ cat update_interval
-    112
-    $ cat temp1_input
-    24031
-
-As shown here, the lm73 driver automatically adjusts any user input for
-'update_interval' via a step function.  Reading back the
-'update_interval' value after a write operation will confirm the
-conversion time actively in use.
-
-Mathematically, the resolution can be derived from the conversion time
-via the following function:
-
-   g(x) = 0.250 * [log(x/14) / log(2)]
-
-where 'x' is the output from 'update_interval' and 'g(x)' is the
-resolution in degrees C per LSB.
-
-Alarm Support
--------------
-
-The LM73 features a simple over-temperature alarm mechanism.  This
-feature is exposed via the sysfs attributes.
-
-The attributes 'temp1_max_alarm' and 'temp1_min_alarm' are flags
-provided by the LM73 that indicate whether the measured temperature has
-passed the 'temp1_max' and 'temp1_min' thresholds, respectively.  These
-values _must_ be read to clear the registers on the LM73.

+Description
+-----------
+
+The LM73 is a digital temperature sensor.  All temperature values are
+given in degrees Celsius.
+
+Measurement Resolution Support
+------------------------------
+
+The LM73 supports four resolutions, defined in terms of degrees C per
+LSB: 0.25, 0.125, 0.0625, and 0.3125.  Changing the resolution mode
+affects the conversion time of the LM73's analog-to-digital converter.
+From userspace, the desired resolution can be specified as a function of
+conversion time via the 'update_interval' sysfs attribute for the
+device.  This attribute will normalize ranges of input values to the
+maximum times defined for the resolution in the datasheet.
+
+    ============= ============= ============
+    Resolution    Conv. Time    Input Range
+    (C/LSB)       (msec)        (msec)
+    ============= ============= ============
+    0.25          14             0..14
+    0.125         28            15..28
+    0.0625        56            29..56
+    0.03125       112           57..infinity
+    ============= ============= ============
+
+The following examples show how the 'update_interval' attribute can be
+used to change the conversion time::
+
+    $ echo 0 > update_interval
+    $ cat update_interval
+    14
+    $ cat temp1_input
+    24250
+
+    $ echo 22 > update_interval
+    $ cat update_interval
+    28
+    $ cat temp1_input
+    24125
+
+    $ echo 56 > update_interval
+    $ cat update_interval
+    56
+    $ cat temp1_input
+    24062
+
+    $ echo 85 > update_interval
+    $ cat update_interval
+    112
+    $ cat temp1_input
+    24031
+
+As shown here, the lm73 driver automatically adjusts any user input for
+'update_interval' via a step function.  Reading back the
+'update_interval' value after a write operation will confirm the
+conversion time actively in use.
+
+Mathematically, the resolution can be derived from the conversion time
+via the following function:
+
+   g(x) = 0.250 * [log(x/14) / log(2)]
+
+where 'x' is the output from 'update_interval' and 'g(x)' is the
+resolution in degrees C per LSB.
+
+Alarm Support
+-------------
+
+The LM73 features a simple over-temperature alarm mechanism.  This
+feature is exposed via the sysfs attributes.
+
+The attributes 'temp1_max_alarm' and 'temp1_min_alarm' are flags
+provided by the LM73 that indicate whether the measured temperature has
+passed the 'temp1_max' and 'temp1_min' thresholds, respectively.  These
+values _must_ be read to clear the registers on the LM73.

-
-The LM75 implements one temperature sensor. Limits can be set through the
-Overtemperature Shutdown register and Hysteresis register. Each value can be
-set and read to half-degree accuracy.
-An alarm is issued (usually to a connected LM78) when the temperature
-gets higher then the Overtemperature Shutdown value; it stays on until
-the temperature falls below the Hysteresis value.
-All temperatures are in degrees Celsius, and are guaranteed within a
-range of -55 to +125 degrees.
-
-The driver caches the values for a period varying between 1 second for the
-slowest chips and 125 ms for the fastest chips; reading it more often
-will do no harm, but will return 'old' values.
-
-The original LM75 was typically used in combination with LM78-like chips
-on PC motherboards, to measure the temperature of the processor(s). Clones
-are now used in various embedded designs.
-
-The LM75 is essentially an industry standard; there may be other
-LM75 clones not listed here, with or without various enhancements,
-that are supported. The clones are not detected by the driver, unless
-they reproduce the exact register tricks of the original LM75, and must
-therefore be instantiated explicitly. Higher resolution up to 16-bit
-is supported by this driver, other specific enhancements are not.
-
-The LM77 is not supported, contrary to what we pretended for a long time.
-Both chips are simply not compatible, value encoding differs.

-and lower limit values.
-
-The LM77 implements 3 limits: low (temp1_min), high (temp1_max) and
-critical (temp1_crit.) It also implements an hysteresis mechanism which
-applies to all 3 limits. The relative difference is stored in a single

-
-This implementation detail implies the following:
-* When setting a limit, its hysteresis will automatically follow, the

-  was 80 degrees C, and the hysteresis was 75 degrees C, and you change
-  the critical limit to 90 degrees C, then the hysteresis will
-  automatically change to 85 degrees C.
-* All 3 hysteresis can't be set independently. We decided to make
-  temp1_crit_hyst writable, while temp1_min_hyst and temp1_max_hyst are
-  read-only. Setting temp1_crit_hyst writes the difference between
-  temp1_crit_hyst and temp1_crit into the chip, and the same relative
-  hysteresis applies automatically to the low and high limits.
-* The limits should be set before the hysteresis.

-Description
------------
-
-This driver implements support for the National Semiconductor LM78, LM78-J
-and LM79. They are described as 'Microprocessor System Hardware Monitors'.
-
-There is almost no difference between the three supported chips. Functionally,
-the LM78 and LM78-J are exactly identical. The LM79 has one more VID line,
-which is used to report the lower voltages newer Pentium processors use.
-From here on, LM7* means either of these three types.
-
-The LM7* implements one temperature sensor, three fan rotation speed sensors,
-seven voltage sensors, VID lines, alarms, and some miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed; it is triggered again
-as soon as it drops below the Hysteresis value. A more useful behavior
-can be found by setting the Hysteresis value to +127 degrees Celsius; in
-this case, alarms are issued during all the time when the actual temperature
-is above the Overtemperature Shutdown value. Measurements are guaranteed
-between -55 and +125 degrees, with a resolution of 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution
-of 0.016 volt.
-
-The VID lines encode the core voltage value: the voltage level your processor
-should work with. This is hardcoded by the mainboard and/or processor itself.
-It is a value in volts. When it is unconnected, you will often find the
-value 3.50 V here.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The LM7* only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

+There is almost no difference between the three supported chips. Functionally,
+the LM78 and LM78-J are exactly identical. The LM79 has one more VID line,
+which is used to report the lower voltages newer Pentium processors use.
+From here on, LM7* means either of these three types.
+
+The LM7* implements one temperature sensor, three fan rotation speed sensors,
+seven voltage sensors, VID lines, alarms, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed; it is triggered again
+as soon as it drops below the Hysteresis value. A more useful behavior
+can be found by setting the Hysteresis value to +127 degrees Celsius; in
+this case, alarms are issued during all the time when the actual temperature
+is above the Overtemperature Shutdown value. Measurements are guaranteed
+between -55 and +125 degrees, with a resolution of 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.
+
+The VID lines encode the core voltage value: the voltage level your processor
+should work with. This is hardcoded by the mainboard and/or processor itself.
+It is a value in volts. When it is unconnected, you will often find the
+value 3.50 V here.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The LM7* only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

-Description
------------
-
-The LM83 is a digital temperature sensor. It senses its own temperature as

-a stripped down version of the LM83 that only supports one external diode.
-Both are compatible with many other devices such as the LM84 and all
-other ADM1021 clones. The main difference between the LM83 and the LM84
-in that the later can only sense the temperature of one external diode.
-
-Using the adm1021 driver for a LM83 should work, but only two temperatures
-will be reported instead of four.
-

-list and an unconfirmed list follow. If you can confirm or infirm the
-fact that any of these motherboards do actually have an LM83, please
-contact us. Note that the LM90 can easily be misdetected as a LM83.
-
-Confirmed motherboards:
-    SBS         P014
-    SBS         PSL09
-
-Unconfirmed motherboards:
-    Gigabyte    GA-8IK1100
-    Iwill       MPX2
-    Soltek      SL-75DRV5
-
-The LM82 is confirmed to have been found on most AMD Geode reference
-designs and test platforms.
-
-The driver has been successfully tested by Magnus Forsström, who I'd
-like to thank here. More testers will be of course welcome.
-
-The fact that the LM83 is only scarcely used can be easily explained.
-Most motherboards come with more than just temperature sensors for
-health monitoring. They also have voltage and fan rotation speed
-sensors. This means that temperature-only chips are usually used as
-secondary chips coupled with another chip such as an IT8705F or similar
-chip, which provides more features. Since systems usually need three
-temperature sensors (motherboard, processor, power supply) and primary
-chips provide some temperature sensors, the secondary chip, if needed,
-won't have to handle more than two temperatures. Thus, ADM1021 clones
-are sufficient, and there is no need for a four temperatures sensor
-chip such as the LM83. The only case where using an LM83 would make
-sense is on SMP systems, such as the above-mentioned Iwill MPX2,
-because you want an additional temperature sensor for each additional
-CPU.
-
-On the SBS P014, this is different, since the LM83 is the only hardware
-monitoring chipset. One temperature sensor is used for the motherboard
-(actually measuring the LM83's own temperature), one is used for the

-Description
------------
-
-This driver implements support for the National Semiconductor LM85 and
-compatible chips including the Analog Devices ADM1027, ADT7463, ADT7468 and
-SMSC EMC6D10x chips family.
-
-The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
-specification. Using an analog to digital converter it measures three (3)
-temperatures and five (5) voltages. It has four (4) 16-bit counters for
-measuring fan speed. Five (5) digital inputs are provided for sampling the
-VID signals from the processor to the VRM. Lastly, there are three (3) PWM
-outputs that can be used to control fan speed.
-
-The voltage inputs have internal scaling resistors so that the following
-voltage can be measured without external resistors:
-
-  2.5V, 3.3V, 5V, 12V, and CPU core voltage (2.25V)
-
-The temperatures measured are one internal diode, and two remote diodes.
-Remote 1 is generally the CPU temperature. These inputs are designed to
-measure a thermal diode like the one in a Pentium 4 processor in a socket
-423 or socket 478 package. They can also measure temperature using a
-transistor like the 2N3904.
-
-A sophisticated control system for the PWM outputs is designed into the
-LM85 that allows fan speed to be adjusted automatically based on any of the
-three temperature sensors. Each PWM output is individually adjustable and
-programmable. Once configured, the LM85 will adjust the PWM outputs in
-response to the measured temperatures without further host intervention.
-This feature can also be disabled for manual control of the PWM's.
-
-Each of the measured inputs (voltage, temperature, fan speed) has
-corresponding high/low limit values. The LM85 will signal an ALARM if any
-measured value exceeds either limit.
-
-The LM85 samples all inputs continuously. The lm85 driver will not read
-the registers more often than once a second. Further, configuration data is
-only read once each 5 minutes. There is twice as much config data as
-measurements, so this would seem to be a worthwhile optimization.
-
-Special Features
-----------------
-
-The LM85 has four fan speed monitoring modes. The ADM1027 has only two.
-Both have special circuitry to compensate for PWM interactions with the
-TACH signal from the fans. The ADM1027 can be configured to measure the
-speed of a two wire fan, but the input conditioning circuitry is different
-for 3-wire and 2-wire mode. For this reason, the 2-wire fan modes are not
-exposed to user control. The BIOS should initialize them to the correct
-mode. If you've designed your own ADM1027, you'll have to modify the
-init_client function and add an insmod parameter to set this up.
-
-To smooth the response of fans to changes in temperature, the LM85 has an
-optional filter for smoothing temperatures. The ADM1027 has the same
-config option but uses it to rate limit the changes to fan speed instead.
-
-The ADM1027, ADT7463 and ADT7468 have a 10-bit ADC and can therefore
-measure temperatures with 0.25 degC resolution. They also provide an offset
-to the temperature readings that is automatically applied during
-measurement. This offset can be used to zero out any errors due to traces
-and placement. The documentation says that the offset is in 0.25 degC
-steps, but in initial testing of the ADM1027 it was 1.00 degC steps. Analog
-Devices has confirmed this "bug". The ADT7463 is reported to work as
-described in the documentation. The current lm85 driver does not show the
-offset register.
-
-The ADT7468 has a high-frequency PWM mode, where all PWM outputs are
-driven by a 22.5 kHz clock. This is a global mode, not per-PWM output,
-which means that setting any PWM frequency above 11.3 kHz will switch
-all 3 PWM outputs to a 22.5 kHz frequency. Conversely, setting any PWM
-frequency below 11.3 kHz will switch all 3 PWM outputs to a frequency
-between 10 and 100 Hz, which can then be tuned separately.
-
-See the vendor datasheets for more information. There is application note
-from National (AN-1260) with some additional information about the LM85.
-The Analog Devices datasheet is very detailed and describes a procedure for
-determining an optimal configuration for the automatic PWM control.
-
-The SMSC EMC6D100 & EMC6D101 monitor external voltages, temperatures, and
-fan speeds. They use this monitoring capability to alert the system to out
-of limit conditions and can automatically control the speeds of multiple
-fans in a PC or embedded system. The EMC6D101, available in a 24-pin SSOP
-package, and the EMC6D100, available in a 28-pin SSOP package, are designed

-
-Configuration Notes
--------------------
-
-Besides standard interfaces driver adds following:
-
-* Temperatures and Zones
-
-Each temperature sensor is associated with a Zone. There are three
-sensors and therefore three zones (# 1, 2 and 3). Each zone has the following
-temperature configuration points:
-
-* temp#_auto_temp_off - temperature below which fans should be off or spinning very low.
-* temp#_auto_temp_min - temperature over which fans start to spin.
-* temp#_auto_temp_max - temperature when fans spin at full speed.
-* temp#_auto_temp_crit - temperature when all fans will run full speed.
-
-* PWM Control
-
-There are three PWM outputs. The LM85 datasheet suggests that the
-pwm3 output control both fan3 and fan4. Each PWM can be individually
-configured and assigned to a zone for its control value. Each PWM can be
-configured individually according to the following options.
-
-* pwm#_auto_pwm_min - this specifies the PWM value for temp#_auto_temp_off
-                      temperature. (PWM value from 0 to 255)
-
-* pwm#_auto_pwm_minctl - this flags selects for temp#_auto_temp_off temperature
-                         the behaviour of fans. Write 1 to let fans spinning at
-			 pwm#_auto_pwm_min or write 0 to let them off.
-
-NOTE: It has been reported that there is a bug in the LM85 that causes the flag
-to be associated with the zones not the PWMs. This contradicts all the
-published documentation. Setting pwm#_min_ctl in this case actually affects all
-PWMs controlled by zone '#'.
-
-* PWM Controlling Zone selection
-
-* pwm#_auto_channels - controls zone that is associated with PWM
-
-Configuration choices:
-
-   Value     Meaning
-  ------  ------------------------------------------------
-      1    Controlled by Zone 1
-      2    Controlled by Zone 2
-      3    Controlled by Zone 3
-     23    Controlled by higher temp of Zone 2 or 3
-    123    Controlled by highest temp of Zone 1, 2 or 3
-      0    PWM always 0%  (off)
-     -1    PWM always 100%  (full on)
-     -2    Manual control (write to 'pwm#' to set)
-
-The National LM85's have two vendor specific configuration
-features. Tach. mode and Spinup Control. For more details on these,
-see the LM85 datasheet or Application Note AN-1260. These features
-are not currently supported by the lm85 driver.
-
-The Analog Devices ADM1027 has several vendor specific enhancements.
-The number of pulses-per-rev of the fans can be set, Tach monitoring
-can be optimized for PWM operation, and an offset can be applied to
-the temperatures to compensate for systemic errors in the
-measurements. These features are not currently supported by the lm85
-driver.
-
-In addition to the ADM1027 features, the ADT7463 and ADT7468 also have
-Tmin control and THERM asserted counts. Automatic Tmin control acts to
-adjust the Tmin value to maintain the measured temperature sensor at a
-specified temperature. There isn't much documentation on this feature in
-the ADT7463 data sheet. This is not supported by current driver.

+Description
+-----------
+
+This driver implements support for the National Semiconductor LM85 and
+compatible chips including the Analog Devices ADM1027, ADT7463, ADT7468 and
+SMSC EMC6D10x chips family.
+
+The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
+specification. Using an analog to digital converter it measures three (3)
+temperatures and five (5) voltages. It has four (4) 16-bit counters for
+measuring fan speed. Five (5) digital inputs are provided for sampling the
+VID signals from the processor to the VRM. Lastly, there are three (3) PWM
+outputs that can be used to control fan speed.
+
+The voltage inputs have internal scaling resistors so that the following
+voltage can be measured without external resistors:
+
+  2.5V, 3.3V, 5V, 12V, and CPU core voltage (2.25V)
+
+The temperatures measured are one internal diode, and two remote diodes.
+Remote 1 is generally the CPU temperature. These inputs are designed to
+measure a thermal diode like the one in a Pentium 4 processor in a socket
+423 or socket 478 package. They can also measure temperature using a
+transistor like the 2N3904.
+
+A sophisticated control system for the PWM outputs is designed into the
+LM85 that allows fan speed to be adjusted automatically based on any of the
+three temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the LM85 will adjust the PWM outputs in
+response to the measured temperatures without further host intervention.
+This feature can also be disabled for manual control of the PWM's.
+
+Each of the measured inputs (voltage, temperature, fan speed) has
+corresponding high/low limit values. The LM85 will signal an ALARM if any
+measured value exceeds either limit.
+
+The LM85 samples all inputs continuously. The lm85 driver will not read
+the registers more often than once a second. Further, configuration data is
+only read once each 5 minutes. There is twice as much config data as
+measurements, so this would seem to be a worthwhile optimization.
+
+Special Features
+----------------
+
+The LM85 has four fan speed monitoring modes. The ADM1027 has only two.
+Both have special circuitry to compensate for PWM interactions with the
+TACH signal from the fans. The ADM1027 can be configured to measure the
+speed of a two wire fan, but the input conditioning circuitry is different
+for 3-wire and 2-wire mode. For this reason, the 2-wire fan modes are not
+exposed to user control. The BIOS should initialize them to the correct
+mode. If you've designed your own ADM1027, you'll have to modify the
+init_client function and add an insmod parameter to set this up.
+
+To smooth the response of fans to changes in temperature, the LM85 has an
+optional filter for smoothing temperatures. The ADM1027 has the same
+config option but uses it to rate limit the changes to fan speed instead.
+
+The ADM1027, ADT7463 and ADT7468 have a 10-bit ADC and can therefore
+measure temperatures with 0.25 degC resolution. They also provide an offset
+to the temperature readings that is automatically applied during
+measurement. This offset can be used to zero out any errors due to traces
+and placement. The documentation says that the offset is in 0.25 degC
+steps, but in initial testing of the ADM1027 it was 1.00 degC steps. Analog
+Devices has confirmed this "bug". The ADT7463 is reported to work as
+described in the documentation. The current lm85 driver does not show the
+offset register.
+
+The ADT7468 has a high-frequency PWM mode, where all PWM outputs are
+driven by a 22.5 kHz clock. This is a global mode, not per-PWM output,
+which means that setting any PWM frequency above 11.3 kHz will switch
+all 3 PWM outputs to a 22.5 kHz frequency. Conversely, setting any PWM
+frequency below 11.3 kHz will switch all 3 PWM outputs to a frequency
+between 10 and 100 Hz, which can then be tuned separately.
+
+See the vendor datasheets for more information. There is application note
+from National (AN-1260) with some additional information about the LM85.
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+
+The SMSC EMC6D100 & EMC6D101 monitor external voltages, temperatures, and
+fan speeds. They use this monitoring capability to alert the system to out
+of limit conditions and can automatically control the speeds of multiple
+fans in a PC or embedded system. The EMC6D101, available in a 24-pin SSOP
+package, and the EMC6D100, available in a 28-pin SSOP package, are designed
+to be register compatible. The EMC6D100 offers all the features of the
+EMC6D101 plus additional voltage monitoring and system control features.
+Unfortunately it is not possible to distinguish between the package
+versions on register level so these additional voltage inputs may read
+zero. EMC6D102 and EMC6D103 feature additional ADC bits thus extending precision
+of voltage and temperature channels.
+
+SMSC EMC6D103S is similar to EMC6D103, but does not support pwm#_auto_pwm_minctl
+and temp#_auto_temp_off.
+
+The LM96000 supports additional high frequency PWM modes (22.5 kHz, 24 kHz,
+25.7 kHz, 27.7 kHz and 30 kHz), which can be configured on a per-PWM basis.
+
+Hardware Configurations
+-----------------------
+
+The LM85 can be jumpered for 3 different SMBus addresses. There are
+no other hardware configuration options for the LM85.
+
+The lm85 driver detects both LM85B and LM85C revisions of the chip. See the
+datasheet for a complete description of the differences. Other than
+identifying the chip, the driver behaves no differently with regard to
+these two chips. The LM85B is recommended for new designs.
+

-Description
------------
-
-This driver implements support for the National Semiconductor LM87
-and the Analog Devices ADM1024.
-
-The LM87 implements up to three temperature sensors, up to two fan
-rotation speed sensors, up to seven voltage sensors, alarms, and some
-miscellaneous stuff. The ADM1024 is fully compatible.
-
-Temperatures are measured in degrees Celsius. Each input has a high
-and low alarm settings. A high limit produces an alarm when the value
-goes above it, and an alarm is also produced when the value goes below
-the low limit.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in
-volts. An alarm is triggered if the voltage has crossed a programmable
-minimum or maximum limit. Note that minimum in this case always means
-'closest to zero'; this is important for negative voltage measurements.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.0 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The lm87 driver only updates its values each 1.0 seconds; reading it more
-often will do no harm, but will return 'old' values.
-
-
-Hardware Configurations
------------------------
-
-The LM87 has four pins which can serve one of two possible functions,
-depending on the hardware configuration.
-
-Some functions share pins, so not all functions are available at the same
-time. Which are depends on the hardware setup. This driver normally
-assumes that firmware configured the chip correctly. Where this is not
-the case, platform code must set the I2C client's platform_data to point
-to a u8 value to be written to the channel register.
-
-For reference, here is the list of exclusive functions:
- - in0+in5 (default) or temp3
- - fan1 (default) or in6
- - fan2 (default) or in7
- - VID lines (default) or IRQ lines (not handled by this driver)

-Description
------------
-
-The LM90 is a digital temperature sensor. It senses its own temperature as
-well as the temperature of up to one external diode. It is compatible
-with many other devices, many of which are supported by this driver.
-
-Note that there is no easy way to differentiate between the MAX6657,
-MAX6658 and MAX6659 variants. The extra features of the MAX6659 are only
-supported by this driver if the chip is located at address 0x4d or 0x4e,
-or if the chip type is explicitly selected as max6659.
-The MAX6680 and MAX6681 only differ in their pinout, therefore they obviously
-can't (and don't need to) be distinguished.
-
-The specificity of this family of chipsets over the ADM1021/LM84
-family is that it features critical limits with hysteresis, and an
-increased resolution of the remote temperature measurement.
-
-The different chipsets of the family are not strictly identical, although
-very similar. For reference, here comes a non-exhaustive list of specific
-features:
-
-LM90:
-  * Filter and alert configuration register at 0xBF.
-  * ALERT is triggered by temperatures over critical limits.
-
-LM86 and LM89:
-  * Same as LM90
-  * Better external channel accuracy
-
-LM99:
-  * Same as LM89
-  * External temperature shifted by 16 degrees down
-
-ADM1032:
-  * Consecutive alert register at 0x22.
-  * Conversion averaging.
-  * Up to 64 conversions/s.
-  * ALERT is triggered by open remote sensor.
-  * SMBus PEC support for Write Byte and Receive Byte transactions.
-
-ADT7461, ADT7461A, NCT1008:
-  * Extended temperature range (breaks compatibility)
-  * Lower resolution for remote temperature
-
-MAX6657 and MAX6658:
-  * Better local resolution
-  * Remote sensor type selection
-
-MAX6659:
-  * Better local resolution
-  * Selectable address
-  * Second critical temperature limit
-  * Remote sensor type selection
-
-MAX6680 and MAX6681:
-  * Selectable address
-  * Remote sensor type selection
-
-MAX6695 and MAX6696:
-  * Better local resolution
-  * Selectable address (max6696)
-  * Second critical temperature limit
-  * Two remote sensors
-
-W83L771W/G
-  * The G variant is lead-free, otherwise similar to the W.
-  * Filter and alert configuration register at 0xBF
-  * Moving average (depending on conversion rate)
-
-W83L771AWG/ASG
-  * Successor of the W83L771W/G, same features.
-  * The AWG and ASG variants only differ in package format.
-  * Diode ideality factor configuration (remote sensor) at 0xE3
-
-SA56004X:
-  * Better local resolution
-
-All temperature values are given in degrees Celsius. Resolution
-is 1.0 degree for the local temperature, 0.125 degree for the remote
-temperature, except for the MAX6657, MAX6658 and MAX6659 which have a
-resolution of 0.125 degree for both temperatures.
-
-Each sensor has its own high and low limits, plus a critical limit.
-Additionally, there is a relative hysteresis value common to both critical
-values. To make life easier to user-space applications, two absolute values
-are exported, one for each channel, but these values are of course linked.
-Only the local hysteresis can be set from user-space, and the same delta
-applies to the remote hysteresis.
-
-The lm90 driver will not update its values more frequently than configured with
-the update_interval attribute; reading them more often will do no harm, but will
-return 'old' values.
-
-SMBus Alert Support
--------------------
-
-This driver has basic support for SMBus alert. When an alert is received,
-the status register is read and the faulty temperature channel is logged.
-
-The Analog Devices chips (ADM1032, ADT7461 and ADT7461A) and ON
-Semiconductor chips (NCT1008) do not implement the SMBus alert protocol
-properly so additional care is needed: the ALERT output is disabled when
-an alert is received, and is re-enabled only when the alarm is gone.
-Otherwise the chip would block alerts from other chips in the bus as long
-as the alarm is active.
-
-PEC Support
------------
-
-The ADM1032 is the only chip of the family which supports PEC. It does
-not support PEC on all transactions though, so some care must be taken.
-
-When reading a register value, the PEC byte is computed and sent by the
-ADM1032 chip. However, in the case of a combined transaction (SMBus Read
-Byte), the ADM1032 computes the CRC value over only the second half of
-the message rather than its entirety, because it thinks the first half
-of the message belongs to a different transaction. As a result, the CRC
-value differs from what the SMBus master expects, and all reads fail.
-
-For this reason, the lm90 driver will enable PEC for the ADM1032 only if
-the bus supports the SMBus Send Byte and Receive Byte transaction types.
-These transactions will be used to read register values, instead of
-SMBus Read Byte, and PEC will work properly.
-
-Additionally, the ADM1032 doesn't support SMBus Send Byte with PEC.
-Instead, it will try to write the PEC value to the register (because the
-SMBus Send Byte transaction with PEC is similar to a Write Byte transaction
-without PEC), which is not what we want. Thus, PEC is explicitly disabled
-on SMBus Send Byte transactions in the lm90 driver.
-
-PEC on byte data transactions represents a significant increase in bandwidth
-usage (+33% for writes, +25% for reads) in normal conditions. With the need
-to use two SMBus transaction for reads, this overhead jumps to +50%. Worse,
-two transactions will typically mean twice as much delay waiting for
-transaction completion, effectively doubling the register cache refresh time.
-I guess reliability comes at a price, but it's quite expensive this time.
-
-So, as not everyone might enjoy the slowdown, PEC can be disabled through
-sysfs. Just write 0 to the "pec" file and PEC will be disabled. Write 1
-to that file to enable PEC again.

+temperature, except for the MAX6657, MAX6658 and MAX6659 which have a
+resolution of 0.125 degree for both temperatures.
+
+Each sensor has its own high and low limits, plus a critical limit.
+Additionally, there is a relative hysteresis value common to both critical
+values. To make life easier to user-space applications, two absolute values
+are exported, one for each channel, but these values are of course linked.
+Only the local hysteresis can be set from user-space, and the same delta
+applies to the remote hysteresis.
+
+The lm90 driver will not update its values more frequently than configured with
+the update_interval attribute; reading them more often will do no harm, but will
+return 'old' values.
+
+SMBus Alert Support
+-------------------
+
+This driver has basic support for SMBus alert. When an alert is received,
+the status register is read and the faulty temperature channel is logged.
+
+The Analog Devices chips (ADM1032, ADT7461 and ADT7461A) and ON
+Semiconductor chips (NCT1008) do not implement the SMBus alert protocol
+properly so additional care is needed: the ALERT output is disabled when
+an alert is received, and is re-enabled only when the alarm is gone.
+Otherwise the chip would block alerts from other chips in the bus as long
+as the alarm is active.
+
+PEC Support
+-----------
+
+The ADM1032 is the only chip of the family which supports PEC. It does
+not support PEC on all transactions though, so some care must be taken.
+
+When reading a register value, the PEC byte is computed and sent by the
+ADM1032 chip. However, in the case of a combined transaction (SMBus Read
+Byte), the ADM1032 computes the CRC value over only the second half of
+the message rather than its entirety, because it thinks the first half
+of the message belongs to a different transaction. As a result, the CRC
+value differs from what the SMBus master expects, and all reads fail.
+
+For this reason, the lm90 driver will enable PEC for the ADM1032 only if
+the bus supports the SMBus Send Byte and Receive Byte transaction types.
+These transactions will be used to read register values, instead of
+SMBus Read Byte, and PEC will work properly.
+
+Additionally, the ADM1032 doesn't support SMBus Send Byte with PEC.
+Instead, it will try to write the PEC value to the register (because the
+SMBus Send Byte transaction with PEC is similar to a Write Byte transaction
+without PEC), which is not what we want. Thus, PEC is explicitly disabled
+on SMBus Send Byte transactions in the lm90 driver.
+
+PEC on byte data transactions represents a significant increase in bandwidth
+usage (+33% for writes, +25% for reads) in normal conditions. With the need
+to use two SMBus transaction for reads, this overhead jumps to +50%. Worse,
+two transactions will typically mean twice as much delay waiting for
+transaction completion, effectively doubling the register cache refresh time.
+I guess reliability comes at a price, but it's quite expensive this time.
+
+So, as not everyone might enjoy the slowdown, PEC can be disabled through
+sysfs. Just write 0 to the "pec" file and PEC will be disabled. Write 1
+to that file to enable PEC again.

-Module Parameters
------------------
-
-* init: integer
-  Set to non-zero to force some initializations (default is 0).

-  A "0" allows SMBus block data transactions if the host supports them.  A "1"
-  disables SMBus block data transactions.  The default is 0.
-* vccp_limit_type: integer array (2)
-  Configures in7 and in8 limit type, where 0 means absolute and non-zero
-  means relative.  "Relative" here refers to "Dynamic Vccp Monitoring using
-  VID" from the datasheet.  It greatly simplifies the interface to allow
-  only one set of limits (absolute or relative) to be in operation at a

-  not a compelling use case for enabling both at once, anyway.  The default
-  is "0,0".
-* vid_agtl: integer
-  A "0" configures the VID pins for V(ih) = 2.1V min, V(il) = 0.8V max.
-  A "1" configures the VID pins for V(ih) = 0.8V min, V(il) = 0.4V max.
-  (The latter setting is referred to as AGTL+ Compatible in the datasheet.)
-  I.e. this parameter controls the VID pin input thresholds; if your VID
-  inputs are not working, try changing this.  The default value is "0".

-
-Hardware Description
---------------------
-
-(from the datasheet)
-
-The LM93 hardware monitor has a two wire digital interface compatible with
-SMBus 2.0. Using an 8-bit ADC, the LM93 measures the temperature of two remote
-diode connected transistors as well as its own die and 16 power supply
-voltages. To set fan speed, the LM93 has two PWM outputs that are each
-controlled by up to four temperature zones. The fancontrol algorithm is lookup
-table based. The LM93 includes a digital filter that can be invoked to smooth
-temperature readings for better control of fan speed. The LM93 has four
-tachometer inputs to measure fan speed. Limit and status registers for all
-measured values are included. The LM93 builds upon the functionality of
-previous motherboard management ASICs and uses some of the LM85's features
-(i.e. smart tachometer mode). It also adds measurement and control support
-for dynamic Vccp monitoring and PROCHOT. It is designed to monitor a dual
-processor Xeon class motherboard with a minimum of external components.
-
-LM94 is also supported in LM93 compatible mode. Extra sensors and features of
-LM94 are not supported.
-
-
-User Interface
---------------
-
-#PROCHOT:
-
-The LM93 can monitor two #PROCHOT signals.  The results are found in the
-sysfs files prochot1, prochot2, prochot1_avg, prochot2_avg, prochot1_max,
-and prochot2_max.  prochot1_max and prochot2_max contain the user limits
-for #PROCHOT1 and #PROCHOT2, respectively.  prochot1 and prochot2 contain
-the current readings for the most recent complete time interval.  The
-value of prochot1_avg and prochot2_avg is something like a 2 period
-exponential moving average (but not quite - check the datasheet). Note
-that this third value is calculated by the chip itself.  All values range
-from 0-255 where 0 indicates no throttling, and 255 indicates > 99.6%.
-
-The monitoring intervals for the two #PROCHOT signals is also configurable.
-These intervals can be found in the sysfs files prochot1_interval and
-prochot2_interval.  The values in these files specify the intervals for
-#P1_PROCHOT and #P2_PROCHOT, respectively.  Selecting a value not in this
-list will cause the driver to use the next largest interval.  The available
-intervals are (in seconds):
-
-#PROCHOT intervals: 0.73, 1.46, 2.9, 5.8, 11.7, 23.3, 46.6, 93.2, 186, 372
-
-It is possible to configure the LM93 to logically short the two #PROCHOT
-signals.  I.e. when #P1_PROCHOT is asserted, the LM93 will automatically
-assert #P2_PROCHOT, and vice-versa.  This mode is enabled by writing a
-non-zero integer to the sysfs file prochot_short.
-
-The LM93 can also override the #PROCHOT pins by driving a PWM signal onto
-one or both of them.  When overridden, the signal has a period of 3.56 ms,
-a minimum pulse width of 5 clocks (at 22.5kHz => 6.25% duty cycle), and
-a maximum pulse width of 80 clocks (at 22.5kHz => 99.88% duty cycle).
-
-The sysfs files prochot1_override and prochot2_override contain boolean
-integers which enable or disable the override function for #P1_PROCHOT and
-#P2_PROCHOT, respectively.  The sysfs file prochot_override_duty_cycle
-contains a value controlling the duty cycle for the PWM signal used when
-the override function is enabled.  This value ranges from 0 to 15, with 0
-indicating minimum duty cycle and 15 indicating maximum.
-
-#VRD_HOT:
-
-The LM93 can monitor two #VRD_HOT signals. The results are found in the
-sysfs files vrdhot1 and vrdhot2. There is one value per file: a boolean for
-which 1 indicates #VRD_HOT is asserted and 0 indicates it is negated. These
-files are read-only.
-
-Smart Tach Mode:
-
-(from the datasheet)
-
-	If a fan is driven using a low-side drive PWM, the tachometer
-	output of the fan is corrupted. The LM93 includes smart tachometer
-	circuitry that allows an accurate tachometer reading to be
-	achieved despite the signal corruption.  In smart tach mode all
-	four signals are measured within 4 seconds.
-
-Smart tach mode is enabled by the driver by writing 1 or 2 (associating the
-the fan tachometer with a pwm) to the sysfs file fan<n>_smart_tach.  A zero
-will disable the function for that fan.  Note that Smart tach mode cannot be
-enabled if the PWM output frequency is 22500 Hz (see below).
-
-Manual PWM:
-
-The LM93 has a fixed or override mode for the two PWM outputs (although, there
-are still some conditions that will override even this mode - see section
-15.10.6 of the datasheet for details.)  The sysfs files pwm1_override
-and pwm2_override are used to enable this mode; each is a boolean integer
-where 0 disables and 1 enables the manual control mode.  The sysfs files pwm1
-and pwm2 are used to set the manual duty cycle; each is an integer (0-255)
-where 0 is 0% duty cycle, and 255 is 100%.  Note that the duty cycle values
-are constrained by the hardware. Selecting a value which is not available
-will cause the driver to use the next largest value.  Also note: when manual
-PWM mode is disabled, the value of pwm1 and pwm2 indicates the current duty
-cycle chosen by the h/w.
-
-PWM Output Frequency:
-
-The LM93 supports several different frequencies for the PWM output channels.
-The sysfs files pwm1_freq and pwm2_freq are used to select the frequency. The
-frequency values are constrained by the hardware.  Selecting a value which is
-not available will cause the driver to use the next largest value.  Also note
-that this parameter has implications for the Smart Tach Mode (see above).
-
-PWM Output Frequencies (in Hz): 12, 36, 48, 60, 72, 84, 96, 22500 (default)
-
-Automatic PWM:
-
-The LM93 is capable of complex automatic fan control, with many different
-points of configuration.  To start, each PWM output can be bound to any
-combination of eight control sources.  The final PWM is the largest of all
-individual control sources to which the PWM output is bound.
-
-The eight control sources are: temp1-temp4 (aka "zones" in the datasheet),
-#PROCHOT 1 & 2, and #VRDHOT 1 & 2.  The bindings are expressed as a bitmask
-in the sysfs files pwm<n>_auto_channels, where a "1" enables the binding, and
-a "0" disables it. The h/w default is 0x0f (all temperatures bound).
-
-	0x01 - Temp 1
-	0x02 - Temp 2
-	0x04 - Temp 3
-	0x08 - Temp 4
-	0x10 - #PROCHOT 1
-	0x20 - #PROCHOT 2
-	0x40 - #VRDHOT 1
-	0x80 - #VRDHOT 2
-
-The function y = f(x) takes a source temperature x to a PWM output y.  This
-function of the LM93 is derived from a base temperature and a table of 12
-temperature offsets.  The base temperature is expressed in degrees C in the
-sysfs files temp<n>_auto_base.  The offsets are expressed in cumulative
-degrees C, with the value of offset <i> for temperature value <n> being
-contained in the file temp<n>_auto_offset<i>.  E.g. if the base temperature
-is 40C:
-
-     offset #	temp<n>_auto_offset<i>	range		pwm
-	 1		0		-		 25.00%
-	 2		0		-		 28.57%
-	 3		1		40C - 41C	 32.14%
-	 4		1		41C - 42C	 35.71%
-	 5		2		42C - 44C	 39.29%
-	 6		2		44C - 46C	 42.86%
-	 7		2		48C - 50C	 46.43%
-	 8		2		50C - 52C	 50.00%
-	 9		2		52C - 54C	 53.57%
-	10		2		54C - 56C	 57.14%
-	11		2		56C - 58C	 71.43%
-	12		2		58C - 60C	 85.71%
-					> 60C		100.00%
-
-Valid offsets are in the range 0C <= x <= 7.5C in 0.5C increments.
-
-There is an independent base temperature for each temperature channel. Note,
-however, there are only two tables of offsets: one each for temp[12] and
-temp[34].  Therefore, any change to e.g. temp1_auto_offset<i> will also
-affect temp2_auto_offset<i>.
-
-The LM93 can also apply hysteresis to the offset table, to prevent unwanted
-oscillation between two steps in the offsets table.  These values are found in
-the sysfs files temp<n>_auto_offset_hyst.  The value in this file has the
-same representation as in temp<n>_auto_offset<i>.
-
-If a temperature reading falls below the base value for that channel, the LM93
-will use the minimum PWM value.  These values are found in the sysfs files
-temp<n>_auto_pwm_min.  Note, there are only two minimums: one each for temp[12]
-and temp[34].  Therefore, any change to e.g. temp1_auto_pwm_min will also
-affect temp2_auto_pwm_min.
-
-PWM Spin-Up Cycle:
-
-A spin-up cycle occurs when a PWM output is commanded from 0% duty cycle to
-some value > 0%.  The LM93 supports a minimum duty cycle during spin-up.  These
-values are found in the sysfs files pwm<n>_auto_spinup_min. The value in this
-file has the same representation as other PWM duty cycle values. The
-duration of the spin-up cycle is also configurable.  These values are found in
-the sysfs files pwm<n>_auto_spinup_time. The value in this file is
-the spin-up time in seconds.  The available spin-up times are constrained by
-the hardware.  Selecting a value which is not available will cause the driver
-to use the next largest value.
-
-Spin-up Durations: 0 (disabled, h/w default), 0.1, 0.25, 0.4, 0.7, 1.0,
-		   2.0, 4.0
-
-#PROCHOT and #VRDHOT PWM Ramping:
-
-If the #PROCHOT or #VRDHOT signals are asserted while bound to a PWM output
-channel, the LM93 will ramp the PWM output up to 100% duty cycle in discrete
-steps. The duration of each step is configurable. There are two files, with
-one value each in seconds: pwm_auto_prochot_ramp and pwm_auto_vrdhot_ramp.
-The available ramp times are constrained by the hardware.  Selecting a value
-which is not available will cause the driver to use the next largest value.
-
-Ramp Times: 0 (disabled, h/w default) to 0.75 in 0.05 second intervals
-
-Fan Boost:
-
-For each temperature channel, there is a boost temperature: if the channel
-exceeds this limit, the LM93 will immediately drive both PWM outputs to 100%.
-This limit is expressed in degrees C in the sysfs files temp<n>_auto_boost.
-There is also a hysteresis temperature for this function: after the boost
-limit is reached, the temperature channel must drop below this value before
-the boost function is disabled.  This temperature is also expressed in degrees
-C in the sysfs files temp<n>_auto_boost_hyst.
-
-GPIO Pins:
-
-The LM93 can monitor the logic level of four dedicated GPIO pins as well as the
-four tach input pins.  GPIO0-GPIO3 correspond to (fan) tach 1-4, respectively.
-All eight GPIOs are read by reading the bitmask in the sysfs file gpio.  The
-LSB is GPIO0, and the MSB is GPIO7.

+
+Hardware Description
+--------------------
+
+(from the datasheet)
+
+The LM93 hardware monitor has a two wire digital interface compatible with
+SMBus 2.0. Using an 8-bit ADC, the LM93 measures the temperature of two remote
+diode connected transistors as well as its own die and 16 power supply
+voltages. To set fan speed, the LM93 has two PWM outputs that are each
+controlled by up to four temperature zones. The fancontrol algorithm is lookup
+table based. The LM93 includes a digital filter that can be invoked to smooth
+temperature readings for better control of fan speed. The LM93 has four
+tachometer inputs to measure fan speed. Limit and status registers for all
+measured values are included. The LM93 builds upon the functionality of
+previous motherboard management ASICs and uses some of the LM85's features
+(i.e. smart tachometer mode). It also adds measurement and control support
+for dynamic Vccp monitoring and PROCHOT. It is designed to monitor a dual
+processor Xeon class motherboard with a minimum of external components.
+
+LM94 is also supported in LM93 compatible mode. Extra sensors and features of
+LM94 are not supported.
+
+
+User Interface
+--------------
+
+#PROCHOT
+^^^^^^^^
+
+The LM93 can monitor two #PROCHOT signals.  The results are found in the
+sysfs files prochot1, prochot2, prochot1_avg, prochot2_avg, prochot1_max,
+and prochot2_max.  prochot1_max and prochot2_max contain the user limits
+for #PROCHOT1 and #PROCHOT2, respectively.  prochot1 and prochot2 contain
+the current readings for the most recent complete time interval.  The
+value of prochot1_avg and prochot2_avg is something like a 2 period
+exponential moving average (but not quite - check the datasheet). Note
+that this third value is calculated by the chip itself.  All values range
+from 0-255 where 0 indicates no throttling, and 255 indicates > 99.6%.
+
+The monitoring intervals for the two #PROCHOT signals is also configurable.
+These intervals can be found in the sysfs files prochot1_interval and
+prochot2_interval.  The values in these files specify the intervals for
+#P1_PROCHOT and #P2_PROCHOT, respectively.  Selecting a value not in this
+list will cause the driver to use the next largest interval.  The available
+intervals are (in seconds):
+
+#PROCHOT intervals:
+	0.73, 1.46, 2.9, 5.8, 11.7, 23.3, 46.6, 93.2, 186, 372
+
+It is possible to configure the LM93 to logically short the two #PROCHOT
+signals.  I.e. when #P1_PROCHOT is asserted, the LM93 will automatically
+assert #P2_PROCHOT, and vice-versa.  This mode is enabled by writing a
+non-zero integer to the sysfs file prochot_short.
+
+The LM93 can also override the #PROCHOT pins by driving a PWM signal onto
+one or both of them.  When overridden, the signal has a period of 3.56 ms,
+a minimum pulse width of 5 clocks (at 22.5kHz => 6.25% duty cycle), and
+a maximum pulse width of 80 clocks (at 22.5kHz => 99.88% duty cycle).
+
+The sysfs files prochot1_override and prochot2_override contain boolean
+integers which enable or disable the override function for #P1_PROCHOT and
+#P2_PROCHOT, respectively.  The sysfs file prochot_override_duty_cycle
+contains a value controlling the duty cycle for the PWM signal used when
+the override function is enabled.  This value ranges from 0 to 15, with 0
+indicating minimum duty cycle and 15 indicating maximum.
+
+#VRD_HOT
+^^^^^^^^
+
+The LM93 can monitor two #VRD_HOT signals. The results are found in the
+sysfs files vrdhot1 and vrdhot2. There is one value per file: a boolean for
+which 1 indicates #VRD_HOT is asserted and 0 indicates it is negated. These
+files are read-only.
+
+Smart Tach Mode (from the datasheet)::
+
+	If a fan is driven using a low-side drive PWM, the tachometer
+	output of the fan is corrupted. The LM93 includes smart tachometer
+	circuitry that allows an accurate tachometer reading to be
+	achieved despite the signal corruption.  In smart tach mode all
+	four signals are measured within 4 seconds.
+
+Smart tach mode is enabled by the driver by writing 1 or 2 (associating the
+the fan tachometer with a pwm) to the sysfs file fan<n>_smart_tach.  A zero
+will disable the function for that fan.  Note that Smart tach mode cannot be
+enabled if the PWM output frequency is 22500 Hz (see below).
+
+Manual PWM
+^^^^^^^^^^
+
+The LM93 has a fixed or override mode for the two PWM outputs (although, there
+are still some conditions that will override even this mode - see section
+15.10.6 of the datasheet for details.)  The sysfs files pwm1_override
+and pwm2_override are used to enable this mode; each is a boolean integer
+where 0 disables and 1 enables the manual control mode.  The sysfs files pwm1
+and pwm2 are used to set the manual duty cycle; each is an integer (0-255)
+where 0 is 0% duty cycle, and 255 is 100%.  Note that the duty cycle values
+are constrained by the hardware. Selecting a value which is not available
+will cause the driver to use the next largest value.  Also note: when manual
+PWM mode is disabled, the value of pwm1 and pwm2 indicates the current duty
+cycle chosen by the h/w.
+
+PWM Output Frequency
+^^^^^^^^^^^^^^^^^^^^
+
+The LM93 supports several different frequencies for the PWM output channels.
+The sysfs files pwm1_freq and pwm2_freq are used to select the frequency. The
+frequency values are constrained by the hardware.  Selecting a value which is
+not available will cause the driver to use the next largest value.  Also note
+that this parameter has implications for the Smart Tach Mode (see above).
+
+PWM Output Frequencies (in Hz):
+	12, 36, 48, 60, 72, 84, 96, 22500 (default)
+
+Automatic PWM
+^^^^^^^^^^^^^
+
+The LM93 is capable of complex automatic fan control, with many different
+points of configuration.  To start, each PWM output can be bound to any
+combination of eight control sources.  The final PWM is the largest of all
+individual control sources to which the PWM output is bound.
+
+The eight control sources are: temp1-temp4 (aka "zones" in the datasheet),
+#PROCHOT 1 & 2, and #VRDHOT 1 & 2.  The bindings are expressed as a bitmask
+in the sysfs files pwm<n>_auto_channels, where a "1" enables the binding, and
+a "0" disables it. The h/w default is 0x0f (all temperatures bound).
+
+	====== ===========
+	0x01   Temp 1
+	0x02   Temp 2
+	0x04   Temp 3
+	0x08   Temp 4
+	0x10   #PROCHOT 1
+	0x20   #PROCHOT 2
+	0x40   #VRDHOT 1
+	0x80   #VRDHOT 2
+	====== ===========
+
+The function y = f(x) takes a source temperature x to a PWM output y.  This
+function of the LM93 is derived from a base temperature and a table of 12
+temperature offsets.  The base temperature is expressed in degrees C in the
+sysfs files temp<n>_auto_base.  The offsets are expressed in cumulative
+degrees C, with the value of offset <i> for temperature value <n> being
+contained in the file temp<n>_auto_offset<i>.  E.g. if the base temperature
+is 40C:
+
+     ========== ======================= =============== =======
+     offset #	temp<n>_auto_offset<i>	range		pwm
+     ========== ======================= =============== =======
+	 1		0		-		 25.00%
+	 2		0		-		 28.57%
+	 3		1		40C - 41C	 32.14%
+	 4		1		41C - 42C	 35.71%
+	 5		2		42C - 44C	 39.29%
+	 6		2		44C - 46C	 42.86%
+	 7		2		48C - 50C	 46.43%
+	 8		2		50C - 52C	 50.00%
+	 9		2		52C - 54C	 53.57%
+	10		2		54C - 56C	 57.14%
+	11		2		56C - 58C	 71.43%
+	12		2		58C - 60C	 85.71%
+	-		-		> 60C		100.00%
+     ========== ======================= =============== =======
+
+Valid offsets are in the range 0C <= x <= 7.5C in 0.5C increments.
+
+There is an independent base temperature for each temperature channel. Note,
+however, there are only two tables of offsets: one each for temp[12] and
+temp[34].  Therefore, any change to e.g. temp1_auto_offset<i> will also
+affect temp2_auto_offset<i>.
+
+The LM93 can also apply hysteresis to the offset table, to prevent unwanted
+oscillation between two steps in the offsets table.  These values are found in
+the sysfs files temp<n>_auto_offset_hyst.  The value in this file has the
+same representation as in temp<n>_auto_offset<i>.
+
+If a temperature reading falls below the base value for that channel, the LM93
+will use the minimum PWM value.  These values are found in the sysfs files
+temp<n>_auto_pwm_min.  Note, there are only two minimums: one each for temp[12]
+and temp[34].  Therefore, any change to e.g. temp1_auto_pwm_min will also
+affect temp2_auto_pwm_min.
+
+PWM Spin-Up Cycle
+^^^^^^^^^^^^^^^^^
+
+A spin-up cycle occurs when a PWM output is commanded from 0% duty cycle to
+some value > 0%.  The LM93 supports a minimum duty cycle during spin-up.  These
+values are found in the sysfs files pwm<n>_auto_spinup_min. The value in this
+file has the same representation as other PWM duty cycle values. The
+duration of the spin-up cycle is also configurable.  These values are found in
+the sysfs files pwm<n>_auto_spinup_time. The value in this file is
+the spin-up time in seconds.  The available spin-up times are constrained by
+the hardware.  Selecting a value which is not available will cause the driver
+to use the next largest value.
+
+Spin-up Durations:
+	0 (disabled, h/w default), 0.1, 0.25, 0.4, 0.7, 1.0, 2.0, 4.0
+
+#PROCHOT and #VRDHOT PWM Ramping
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If the #PROCHOT or #VRDHOT signals are asserted while bound to a PWM output
+channel, the LM93 will ramp the PWM output up to 100% duty cycle in discrete
+steps. The duration of each step is configurable. There are two files, with
+one value each in seconds: pwm_auto_prochot_ramp and pwm_auto_vrdhot_ramp.
+The available ramp times are constrained by the hardware.  Selecting a value
+which is not available will cause the driver to use the next largest value.
+
+Ramp Times:
+	0 (disabled, h/w default) to 0.75 in 0.05 second intervals
+
+Fan Boost
+^^^^^^^^^
+
+For each temperature channel, there is a boost temperature: if the channel
+exceeds this limit, the LM93 will immediately drive both PWM outputs to 100%.
+This limit is expressed in degrees C in the sysfs files temp<n>_auto_boost.
+There is also a hysteresis temperature for this function: after the boost
+limit is reached, the temperature channel must drop below this value before
+the boost function is disabled.  This temperature is also expressed in degrees
+C in the sysfs files temp<n>_auto_boost_hyst.
+
+GPIO Pins
+^^^^^^^^^
+
+The LM93 can monitor the logic level of four dedicated GPIO pins as well as the
+four tach input pins.  GPIO0-GPIO3 correspond to (fan) tach 1-4, respectively.
+All eight GPIOs are read by reading the bitmask in the sysfs file gpio.  The
+LSB is GPIO0, and the MSB is GPIO7.

-The LTC2945  is a rail-to-rail system monitor that measures current, voltage,

-Usage Notes
------------
-
-This driver does not probe for LTC2945 devices, since there is no register

-the devices explicitly.
-
-Example: the following will load the driver for an LTC2945 at address 0x10

-real voltage by multiplying the reported value with (R1+R2)/R2, where R1 is the
-value of the divider resistor against the measured voltage and R2 is the value
-of the divider resistor against Ground.
-
-Current reading provided by this driver is reported as obtained from the ADC
-Current Sense register. The reported value assumes that a 1 mOhm sense resistor
-is installed. If a different sense resistor is installed, calculate the real
-current by dividing the reported value by the sense resistor value in mOhm.

-
-LTC2990 is a Quad I2C Voltage, Current and Temperature Monitor.
-The chip's inputs can measure 4 voltages, or two inputs together (1+2 and 3+4)
-can be combined to measure a differential voltage, which is typically used to
-measure current through a series resistor, or a temperature with an external
-diode.

-This driver does not probe for PMBus devices. You will have to instantiate
-devices explicitly.

-mode of the chip.

-in[1-4]_input Voltage at V[1-4] pin in millivolt
-temp2_input   External temperature sensor TR1 in millidegrees Celcius
-temp3_input   External temperature sensor TR2 in millidegrees Celcius
-curr1_input   Current in mA across V1-V2 assuming a 1mOhm sense resistor
-curr2_input   Current in mA across V3-V4 assuming a 1mOhm sense resistor
-
-The "curr*_input" measurements actually report the voltage drop across the
-input pins in microvolts. This is equivalent to the current through a 1mOhm
-sense resistor. Divide the reported value by the actual sense resistor value
-in mOhm to get the actual value.

-The LTC4245 chip can be configured to sample all GPIO pins with two methods:

-Description
------------
-
-[From datasheets] The MAX16065/MAX16066 flash-configurable system managers
-monitor and sequence multiple system voltages. The MAX16065/MAX16066 can also
-accurately monitor (+/-2.5%) one current channel using a dedicated high-side
-current-sense amplifier. The MAX16065 manages up to twelve system voltages
-simultaneously, and the MAX16066 manages up to eight supply voltages.
-
-The MAX16067 flash-configurable system manager monitors and sequences multiple
-system voltages. The MAX16067 manages up to six system voltages simultaneously.
-
-The MAX16068 flash-configurable system manager monitors and manages up to six
-system voltages simultaneously.
-
-The MAX16070/MAX16071 flash-configurable system monitors supervise multiple
-system voltages. The MAX16070/MAX16071 can also accurately monitor (+/-2.5%)
-one current channel using a dedicated high-side current-sense amplifier. The
-MAX16070 monitors up to twelve system voltages simultaneously, and the MAX16071
-monitors up to eight supply voltages.
-
-Each monitored channel has its own low and high critical limits. MAX16065,
-MAX16066, MAX16070, and MAX16071 support an additional limit which is
-configurable as either low or high secondary limit. MAX16065, MAX16066,
-MAX16070, and MAX16071 also support supply current monitoring.
-
-
-Usage Notes
------------
-
-This driver does not probe for devices, since there is no register which
-can be safely used to identify the chip. You will have to instantiate
-the devices explicitly. Please see Documentation/i2c/instantiating-devices for
-details.
-
-WARNING: Do not access chip registers using the i2cdump command, and do not use
-any of the i2ctools commands on a command register (0xa5 to 0xac). The chips
-supported by this driver interpret any access to a command register (including
-read commands) as request to execute the command in question. This may result in
-power loss, board resets, and/or Flash corruption. Worst case, your board may
-turn into a brick.

-Maxim MAX197 driver
-===================
-
-Author:
-  * Vivien Didelot <vivien.didelot@savoirfairelinux.com>
-
-Supported chips:
-  * Maxim MAX197
-    Prefix: 'max197'
-    Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX197.pdf
-
-  * Maxim MAX199
-    Prefix: 'max199'
-    Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX199.pdf
-
-Description
------------
-
-The A/D converters MAX197, and MAX199 are both 8-Channel, Multi-Range, 5V,
-12-Bit DAS with 8+4 Bus Interface and Fault Protection.
-
-The available ranges for the MAX197 are {0,-5V} to 5V, and {0,-10V} to 10V,
-while they are {0,-2V} to 2V, and {0,-4V} to 4V on the MAX199.
-
-Platform data
--------------
-
-The MAX197 platform data (defined in linux/platform_data/max197.h) should be
-filled with a pointer to a conversion function, defined like:
-
-    int convert(u8 ctrl);
-
-ctrl is the control byte to write to start a new conversion.
-On success, the function must return the 12-bit raw value read from the chip,
-or a negative error code otherwise.
-
-Control byte format:
-
-Bit     Name       Description
-7,6     PD1,PD0    Clock and Power-Down modes
-5       ACQMOD     Internal or External Controlled Acquisition
-4       RNG        Full-scale voltage magnitude at the input
-3       BIP        Unipolar or Bipolar conversion mode
-2,1,0   A2,A1,A0   Channel
-
-Sysfs interface
----------------
-
-* in[0-7]_input: The conversion value for the corresponding channel.
-                 RO
-
-* in[0-7]_min:   The lower limit (in mV) for the corresponding channel.
-                 For the MAX197, it will be adjusted to -10000, -5000, or 0.
-                 For the MAX199, it will be adjusted to -4000, -2000, or 0.
-                 RW
-

-Description
------------
-
-This driver implements support for the Maxim MAX31790 chip.
-
-The MAX31790 controls the speeds of up to six fans using six independent
-PWM outputs. The desired fan speeds (or PWM duty cycles) are written
-through the I2C interface. The outputs drive "4-wire" fans directly,
-or can be used to modulate the fan's power terminals using an external
-pass transistor.
-
-Tachometer inputs monitor fan tachometer logic outputs for precise (+/-1%)
-monitoring and control of fan RPM as well as detection of fan failure.
-Six pins are dedicated tachometer inputs. Any of the six PWM outputs can
-also be configured to serve as tachometer inputs.

+Description
+-----------
+
+This driver implements support for the Maxim MAX31790 chip.
+
+The MAX31790 controls the speeds of up to six fans using six independent
+PWM outputs. The desired fan speeds (or PWM duty cycles) are written
+through the I2C interface. The outputs drive "4-wire" fans directly,
+or can be used to modulate the fan's power terminals using an external
+pass transistor.
+
+Tachometer inputs monitor fan tachometer logic outputs for precise (+/-1%)
+monitoring and control of fan RPM as well as detection of fan failure.
+Six pins are dedicated tachometer inputs. Any of the six PWM outputs can
+also be configured to serve as tachometer inputs.

-Description
------------
-
-This driver supports hardware monitoring for Maxim MAX34440 PMBus 6-Channel
-Power-Supply Manager, MAX34441 PMBus 5-Channel Power-Supply Manager
-and Intelligent Fan Controller, and MAX34446 PMBus Power-Supply Data Logger.
-It also supports the MAX34451, MAX34460, and MAX34461 PMBus Voltage Monitor &
-Sequencers. The MAX34451 supports monitoring voltage or current of 12 channels
-based on GIN pins. The MAX34460 supports 12 voltage channels, and the MAX34461
-supports 16 voltage channels.
-
-The driver is a client driver to the core PMBus driver. Please see
-Documentation/hwmon/pmbus for details on PMBus client drivers.
-
-
-Usage Notes
------------
-
-This driver does not auto-detect devices. You will have to instantiate the
-devices explicitly. Please see Documentation/i2c/instantiating-devices for
-details.
-
-For MAX34446, the value of the currX_crit attribute determines if current or
-voltage measurement is enabled for a given channel. Voltage measurement is
-enabled if currX_crit is set to 0; current measurement is enabled if the
-attribute is set to a positive value. Power measurement is only enabled if
-channel 1 (3) is configured for voltage measurement, and channel 2 (4) is
-configured for current measurement.
-
-

-Description
------------
-
-This driver implements support for the Maxim MAX6650 and MAX6651.
-
-The 2 devices are very similar, but the MAX6550 has a reduced feature
-set, e.g. only one fan-input, instead of 4 for the MAX6651.
-
-The driver is not able to distinguish between the 2 devices.
-
-The driver provides the following sensor accesses in sysfs:
-
-fan1_input	ro	fan tachometer speed in RPM
-fan2_input	ro	"
-fan3_input	ro	"
-fan4_input	ro	"
-fan1_target	rw	desired fan speed in RPM (closed loop mode only)
-pwm1_enable	rw	regulator mode, 0=full on, 1=open loop, 2=closed loop
-			3=off
-pwm1		rw	relative speed (0-255), 255=max. speed.
-			Used in open loop mode only.
-fan1_div	rw	sets the speed range the inputs can handle. Legal
-			values are 1, 2, 4, and 8. Use lower values for
-			faster fans.
-
-Usage notes
------------
-
-This driver does not auto-detect devices. You will have to instantiate the
-devices explicitly. Please see Documentation/i2c/instantiating-devices for
-details.
-
-Module parameters
------------------
-
-If your board has a BIOS that initializes the MAX6650/6651 correctly, you can
-simply load your module without parameters. It won't touch the configuration
-registers then. If your board BIOS doesn't initialize the chip, or you want
-different settings, you can set the following parameters:
-
-voltage_12V: 5=5V fan, 12=12V fan, 0=don't change
-prescaler: Possible values are 1,2,4,8,16, or 0 for don't change
-clock: The clock frequency in Hz of the chip the driver should assume [254000]
-
-Please have a look at the MAX6650/6651 data sheet and make sure that you fully
-understand the meaning of these parameters before you attempt to change them.

-Description
------------
-
-The Freescale MC13783 and MC13892 are Power Management and Audio Circuits.
-Among other things they contain a 10-bit A/D converter. The converter has 16
-(MC13783) resp. 12 (MC13892) channels which can be used in different modes. The
-A/D converter has a resolution of 2.25mV.
-
-Some channels can be used as General Purpose inputs or in a dedicated mode with
-a chip internal scaling applied .
-
-Currently the driver only supports the Application Supply channel (BP / BPSNS),
-the General Purpose inputs and touchscreen.
-
-See the following tables for the meaning of the different channels and their
-chip internal scaling:

+Description
+-----------
+
+The Freescale MC13783 and MC13892 are Power Management and Audio Circuits.
+Among other things they contain a 10-bit A/D converter. The converter has 16
+(MC13783) resp. 12 (MC13892) channels which can be used in different modes. The
+A/D converter has a resolution of 2.25mV.
+
+Some channels can be used as General Purpose inputs or in a dedicated mode with
+a chip internal scaling applied .
+
+Currently the driver only supports the Application Supply channel (BP / BPSNS),
+the General Purpose inputs and touchscreen.
+
+See the following tables for the meaning of the different channels and their
+chip internal scaling:

-
-Description
------------
-
-This driver implements support for the Nuvoton NCT6683D eSIO chip.
-
-The chips implement up to shared 32 temperature and voltage sensors.
-It supports up to 16 fan rotation sensors and up to 8 fan control engines.
-
-Temperatures are measured in degrees Celsius. Measurement resolution is
-0.5 degrees C.
-
-Voltage sensors (also known as IN sensors) report their values in millivolts.
-
-Fan rotation speeds are reported in RPM (rotations per minute).
-
-Usage Note
-----------
-
-Limit register locations on Intel boards with EC firmware version 1.0
-build date 04/03/13 do not match the register locations in the Nuvoton
-datasheet. Nuvoton confirms that Intel uses a special firmware version
-with different register addresses. The specification describing the Intel
-firmware is held under NDA by Nuvoton and Intel and not available
-to the public.
-
-Some of the register locations can be reverse engineered; others are too
-well hidden. Given this, writing any values from the operating system is
-considered too risky with this firmware and has been disabled. All limits
-must all be written from the BIOS.
-
-The driver has only been tested with the Intel firmware, and by default
-only instantiates on Intel boards. To enable it on non-Intel boards,
-set the 'force' module parameter to 1.
-
-Tested Boards and Firmware Versions

+This driver implements support for the Nuvoton NCT6683D eSIO chip.
+
+The chips implement up to shared 32 temperature and voltage sensors.
+It supports up to 16 fan rotation sensors and up to 8 fan control engines.
+
+Temperatures are measured in degrees Celsius. Measurement resolution is
+0.5 degrees C.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+
+Fan rotation speeds are reported in RPM (rotations per minute).
+
+Usage Note
+----------
+
+Limit register locations on Intel boards with EC firmware version 1.0
+build date 04/03/13 do not match the register locations in the Nuvoton
+datasheet. Nuvoton confirms that Intel uses a special firmware version
+with different register addresses. The specification describing the Intel
+firmware is held under NDA by Nuvoton and Intel and not available
+to the public.
+
+Some of the register locations can be reverse engineered; others are too
+well hidden. Given this, writing any values from the operating system is
+considered too risky with this firmware and has been disabled. All limits
+must all be written from the BIOS.
+
+The driver has only been tested with the Intel firmware, and by default
+only instantiates on Intel boards. To enable it on non-Intel boards,
+set the 'force' module parameter to 1.

-Description
------------
-
-This driver implements support for the Nuvoton NCT6775F, NCT6776F, and NCT6779D
-and compatible super I/O chips.
-
-The chips support up to 25 temperature monitoring sources. Up to 6 of those are
-direct temperature sensor inputs, the others are special sources such as PECI,
-PCH, and SMBUS. Depending on the chip type, 2 to 6 of the temperature sources
-can be monitored and compared against minimum, maximum, and critical
-temperatures. The driver reports up to 10 of the temperatures to the user.
-There are 4 to 5 fan rotation speed sensors, 8 to 15 analog voltage sensors,
-one VID, alarms with beep warnings (control unimplemented), and some automatic
-fan regulation strategies (plus manual fan control mode).
-
-The temperature sensor sources on all chips are configurable. The configured
-source for each of the temperature sensors is provided in tempX_label.
-
-Temperatures are measured in degrees Celsius and measurement resolution is
-either 1 degC or 0.5 degC, depending on the temperature source and
-configuration. An alarm is triggered when the temperature gets higher than
-the high limit; it stays on until the temperature falls below the hysteresis
-value. Alarms are only supported for temp1 to temp6, depending on the chip type.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. On
-NCT6775F, fan readings can be divided by a programmable divider (1, 2, 4, 8,
-16, 32, 64 or 128) to give the readings more range or accuracy; the other chips
-do not have a fan speed divider. The driver sets the most suitable fan divisor
-itself; specifically, it increases the divider value each time a fan speed
-reading returns an invalid value, and it reduces it if the fan speed reading
-is lower than optimal. Some fans might not be present because they share pins
-with other functions.
-
-Voltage sensors (also known as IN sensors) report their values in millivolts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit.
-
-The driver supports automatic fan control mode known as Thermal Cruise.
-In this mode, the chip attempts to keep the measured temperature in a
-predefined temperature range. If the temperature goes out of range, fan
-is driven slower/faster to reach the predefined range again.
-
-The mode works for fan1-fan5.
-
-sysfs attributes
-----------------
-
-pwm[1-7] - this file stores PWM duty cycle or DC value (fan speed) in range:
-	   0 (lowest speed) to 255 (full)
-
-pwm[1-7]_enable - this file controls mode of fan/temperature control:
-	* 0 Fan control disabled (fans set to maximum speed)
-	* 1 Manual mode, write to pwm[0-5] any value 0-255
-	* 2 "Thermal Cruise" mode
-	* 3 "Fan Speed Cruise" mode
-	* 4 "Smart Fan III" mode (NCT6775F only)
-	* 5 "Smart Fan IV" mode
-
-pwm[1-7]_mode - controls if output is PWM or DC level
-        * 0 DC output
-        * 1 PWM output
-
-Common fan control attributes
------------------------------
-
-pwm[1-7]_temp_sel	Temperature source. Value is temperature sensor index.
-			For example, select '1' for temp1_input.
-pwm[1-7]_weight_temp_sel
-			Secondary temperature source. Value is temperature
-			sensor index. For example, select '1' for temp1_input.
-			Set to 0 to disable secondary temperature control.
-
-If secondary temperature functionality is enabled, it is controlled with the
-following attributes.
-
-pwm[1-7]_weight_duty_step
-			Duty step size.
-pwm[1-7]_weight_temp_step
-			Temperature step size. With each step over
-			temp_step_base, the value of weight_duty_step is added
-			to the current pwm value.
-pwm[1-7]_weight_temp_step_base
-			Temperature at which secondary temperature control kicks
-			in.
-pwm[1-7]_weight_temp_step_tol
-			Temperature step tolerance.
-
-Thermal Cruise mode (2)
------------------------
-
-If the temperature is in the range defined by:
-
-pwm[1-7]_target_temp	Target temperature, unit millidegree Celsius
-			(range 0 - 127000)
-pwm[1-7]_temp_tolerance
-			Target temperature tolerance, unit millidegree Celsius
-
-there are no changes to fan speed. Once the temperature leaves the interval, fan
-speed increases (if temperature is higher that desired) or decreases (if
-temperature is lower than desired), using the following limits and time
-intervals.
-
-pwm[1-7]_start		fan pwm start value (range 1 - 255), to start fan
-			when the temperature is above defined range.
-pwm[1-7]_floor		lowest fan pwm (range 0 - 255) if temperature is below
-			the defined range. If set to 0, the fan is expected to
-			stop if the temperature is below the defined range.
-pwm[1-7]_step_up_time	milliseconds before fan speed is increased
-pwm[1-7]_step_down_time	milliseconds before fan speed is decreased
-pwm[1-7]_stop_time	how many milliseconds must elapse to switch
-			corresponding fan off (when the temperature was below
-			defined range).
-
-Speed Cruise mode (3)
----------------------
-
-This modes tries to keep the fan speed constant.
-
-fan[1-7]_target		Target fan speed
-fan[1-7]_tolerance
-			Target speed tolerance
-
-
-Untested; use at your own risk.
-
-Smart Fan IV mode (5)
----------------------
-
-This mode offers multiple slopes to control the fan speed. The slopes can be
-controlled by setting the pwm and temperature attributes. When the temperature
-rises, the chip will calculate the DC/PWM output based on the current slope.
-There are up to seven data points depending on the chip type. Subsequent data
-points should be set to higher temperatures and higher pwm values to achieve
-higher fan speeds with increasing temperature. The last data point reflects
-critical temperature mode, in which the fans should run at full speed.
-
-pwm[1-7]_auto_point[1-7]_pwm
-			pwm value to be set if temperature reaches matching
-			temperature range.
-pwm[1-7]_auto_point[1-7]_temp
-			Temperature over which the matching pwm is enabled.
-pwm[1-7]_temp_tolerance
-			Temperature tolerance, unit millidegree Celsius
-pwm[1-7]_crit_temp_tolerance
-			Temperature tolerance for critical temperature,
-			unit millidegree Celsius
-
-pwm[1-7]_step_up_time	milliseconds before fan speed is increased
-pwm[1-7]_step_down_time	milliseconds before fan speed is decreased
-
-Usage Notes
------------
-
-On various ASUS boards with NCT6776F, it appears that CPUTIN is not really
-connected to anything and floats, or that it is connected to some non-standard
-temperature measurement device. As a result, the temperature reported on CPUTIN
-will not reflect a usable value. It often reports unreasonably high
-temperatures, and in some cases the reported temperature declines if the actual
-temperature increases (similar to the raw PECI temperature value - see PECI
-specification for details). CPUTIN should therefore be be ignored on ASUS
-boards. The CPU temperature on ASUS boards is reported from PECI 0.

-    Datasheet: Not available, driver was reverse engineered based upon the

-
-Author:
-  Adam Baker <linux@baker-net.org.uk>
-
-Description
------------
-
-This chip is known to be used in the Zyxel NSA320 and NSA325 NAS Units and
-also in some variants of the NSA310 but the driver has only been tested
-on the NSA320. In all of these devices it is connected to the same 3 GPIO
-lines which are used to provide chip select, clock and data lines. The
-interface behaves similarly to SPI but at much lower speeds than are normally
-used for SPI.
-
-Following each chip select pulse the chip will generate a single 32 bit word
-that contains 0x55 as a marker to indicate that data is being read correctly,
-followed by an 8 bit fan speed in 100s of RPM and a 16 bit temperature in
-tenths of a degree.
-
-
-sysfs-Interface
----------------
-
-temp1_input - temperature input
-fan1_input - fan speed
-
-Notes
------
-
-The access timings used in the driver are the same as used in the Zyxel
-provided kernel. Testing has shown that if the delay between chip select and
-the first clock pulse is reduced from 100 ms to just under 10ms then the chip
-will not produce any output. If the duration of either phase of the clock
-is reduced from 100 us to less than 15 us then data pulses are likely to be
-read twice corrupting the output. The above analysis is based upon a sample
-of one unit but suggests that the Zyxel provided delay values include a
-reasonable tolerance.
-
-The driver incorporates a limit that it will not check for updated values
-faster than once a second. This is because the hardware takes a relatively long
-time to read the data from the device and when it does it reads both temp and
-fan speed. As the most likely case for two accesses in quick succession is
-to read both of these values avoiding a second read delay is desirable.

-Kernel driver occ-hwmon
-=======================
-
-Supported chips:
-  * POWER8
-  * POWER9
-
-Author: Eddie James <eajames@linux.ibm.com>
-
-Description
------------
-
-This driver supports hardware monitoring for the On-Chip Controller (OCC)
-embedded on POWER processors. The OCC is a device that collects and aggregates
-sensor data from the processor and the system. The OCC can provide the raw
-sensor data as well as perform thermal and power management on the system.
-
-The P8 version of this driver is a client driver of I2C. It may be probed
-manually if an "ibm,p8-occ-hwmon" compatible device is found under the
-appropriate I2C bus node in the device-tree.
-
-The P9 version of this driver is a client driver of the FSI-based OCC driver.
-It will be probed automatically by the FSI-based OCC driver.
-
-Sysfs entries
--------------
-
-The following attributes are supported. All attributes are read-only unless
-specified.
-
-The OCC sensor ID is an integer that represents the unique identifier of the
-sensor with respect to the OCC. For example, a temperature sensor for the third
-DIMM slot in the system may have a sensor ID of 7. This mapping is unavailable
-to the device driver, which must therefore export the sensor ID as-is.
-
-Some entries are only present with certain OCC sensor versions or only on
-certain OCCs in the system. The version number is not exported to the user
-but can be inferred.
-
-temp[1-n]_label		OCC sensor ID.
-[with temperature sensor version 1]
-    temp[1-n]_input	Measured temperature of the component in millidegrees
-			Celsius.
-[with temperature sensor version >= 2]
-    temp[1-n]_type		The FRU (Field Replaceable Unit) type
-				(represented by an integer) for the component
-				that this sensor measures.
-    temp[1-n]_fault		Temperature sensor fault boolean; 1 to indicate
-				that a fault is present or 0 to indicate that
-				no fault is present.
-    [with type == 3 (FRU type is VRM)]
-        temp[1-n]_alarm		VRM temperature alarm boolean; 1 to indicate
-				alarm, 0 to indicate no alarm
-    [else]
-        temp[1-n]_input		Measured temperature of the component in
-				millidegrees Celsius.
-
-freq[1-n]_label		OCC sensor ID.
-freq[1-n]_input		Measured frequency of the component in MHz.
-
-power[1-n]_input	Latest measured power reading of the component in
-			microwatts.
-power[1-n]_average	Average power of the component in microwatts.
-power[1-n]_average_interval	The amount of time over which the power average
-				was taken in microseconds.
-[with power sensor version < 2]
-    power[1-n]_label	OCC sensor ID.
-[with power sensor version >= 2]
-    power[1-n]_label	OCC sensor ID + function ID + channel in the form
-			of a string, delimited by underscores, i.e. "0_15_1".
-			Both the function ID and channel are integers that
-			further identify the power sensor.
-[with power sensor version 0xa0]
-    power[1-n]_label	OCC sensor ID + sensor type in the form of a string,
-			delimited by an underscore, i.e. "0_system". Sensor
-			type will be one of "system", "proc", "vdd" or "vdn".
-			For this sensor version, OCC sensor ID will be the same
-			for all power sensors.
-[present only on "master" OCC; represents the whole system power; only one of
- this type of power sensor will be present]
-    power[1-n]_label		"system"
-    power[1-n]_input		Latest system output power in microwatts.
-    power[1-n]_cap		Current system power cap in microwatts.
-    power[1-n]_cap_not_redundant	System power cap in microwatts when
-					there is not redundant power.
-    power[1-n]_cap_max		Maximum power cap that the OCC can enforce in
-				microwatts.
-    power[1-n]_cap_min		Minimum power cap that the OCC can enforce in
-				microwatts.
-    power[1-n]_cap_user		The power cap set by the user, in microwatts.
-				This attribute will return 0 if no user power
-				cap has been set. This attribute is read-write,
-				but writing any precision below watts will be
-				ignored, i.e. requesting a power cap of
-				500900000 microwatts will result in a power cap

+Kernel driver occ-hwmon
+=======================
+
+Supported chips:
+
+  * POWER8
+  * POWER9
+
+Author: Eddie James <eajames@linux.ibm.com>
+
+Description
+-----------
+
+This driver supports hardware monitoring for the On-Chip Controller (OCC)
+embedded on POWER processors. The OCC is a device that collects and aggregates
+sensor data from the processor and the system. The OCC can provide the raw
+sensor data as well as perform thermal and power management on the system.
+
+The P8 version of this driver is a client driver of I2C. It may be probed
+manually if an "ibm,p8-occ-hwmon" compatible device is found under the
+appropriate I2C bus node in the device-tree.
+
+The P9 version of this driver is a client driver of the FSI-based OCC driver.
+It will be probed automatically by the FSI-based OCC driver.
+
+Sysfs entries
+-------------
+
+The following attributes are supported. All attributes are read-only unless
+specified.
+
+The OCC sensor ID is an integer that represents the unique identifier of the
+sensor with respect to the OCC. For example, a temperature sensor for the third
+DIMM slot in the system may have a sensor ID of 7. This mapping is unavailable
+to the device driver, which must therefore export the sensor ID as-is.
+
+Some entries are only present with certain OCC sensor versions or only on
+certain OCCs in the system. The version number is not exported to the user
+but can be inferred.

-
-Description
------------
-
-The National Semiconductor PC87360 Super I/O chip contains monitoring and
-PWM control circuitry for two fans. The PC87363 chip is similar, and the
-PC87364 chip has monitoring and PWM control for a third fan.
-

-
-The driver assumes that no more than one chip is present, and one of the
-standard Super I/O addresses is used (0x2E/0x2F or 0x4E/0x4F)
-
-Fan Monitoring
---------------
-
-Fan rotation speeds are reported in RPM (revolutions per minute). An alarm
-is triggered if the rotation speed has dropped below a programmable limit.
-A different alarm is triggered if the fan speed is too low to be measured.
-
-Fan readings are affected by a programmable clock divider, giving the
-readings more range or accuracy. Usually, users have to learn how it works,
-but this driver implements dynamic clock divider selection, so you don't
-have to care no more.
-
-For reference, here are a few values about clock dividers:
-
-                slowest         accuracy        highest
-                measurable      around 3000     accurate
-    divider     speed (RPM)     RPM (RPM)       speed (RPM)
-         1        1882              18           6928
-         2         941              37           4898
-         4         470              74           3464
-         8         235             150           2449
-
-For the curious, here is how the values above were computed:
- * slowest measurable speed: clock/(255*divider)
- * accuracy around 3000 RPM: 3000^2/clock
- * highest accurate speed: sqrt(clock*100)
-The clock speed for the PC87360 family is 480 kHz. I arbitrarily chose 100
-RPM as the lowest acceptable accuracy.
-
-As mentioned above, you don't have to care about this no more.
-
-Note that not all RPM values can be represented, even when the best clock
-divider is selected. This is not only true for the measured speeds, but
-also for the programmable low limits, so don't be surprised if you try to
-set, say, fan1_min to 2900 and it finally reads 2909.
-
-
-Fan Control
------------
-
-PWM (pulse width modulation) values range from 0 to 255, with 0 meaning
-that the fan is stopped, and 255 meaning that the fan goes at full speed.
-
-Be extremely careful when changing PWM values. Low PWM values, even
-non-zero, can stop the fan, which may cause irreversible damage to your
-hardware if temperature increases too much. When changing PWM values, go
-step by step and keep an eye on temperatures.
-
-One user reported problems with PWM. Changing PWM values would break fan
-speed readings. No explanation nor fix could be found.
-
-
-Temperature Monitoring
-----------------------
-
-Temperatures are reported in degrees Celsius. Each temperature measured has
-associated low, high and overtemperature limits, each of which triggers an
-alarm when crossed.
-
-The first two temperature channels are external. The third one (PC87366
-only) is internal.
-
-The PC87366 has three additional temperature channels, based on
-thermistors (as opposed to thermal diodes for the first three temperature
-channels). For technical reasons, these channels are held by the VLM
-(voltage level monitor) logical device, not the TMS (temperature
-measurement) one. As a consequence, these temperatures are exported as
-voltages, and converted into temperatures in user-space.
-
-Note that these three additional channels share their pins with the
-external thermal diode channels, so you (physically) can't use them all at
-the same time. Although it should be possible to mix the two sensor types,
-the documents from National Semiconductor suggest that motherboard
-manufacturers should choose one type and stick to it. So you will more
-likely have either channels 1 to 3 (thermal diodes) or 3 to 6 (internal
-thermal diode, and thermistors).
-
-
-Voltage Monitoring
-------------------
-
-Voltages are reported relatively to a reference voltage, either internal or
-external. Some of them (in7:Vsb, in8:Vdd and in10:AVdd) are divided by two
-internally, you will have to compensate in sensors.conf. Others (in0 to in6)
-are likely to be divided externally. The meaning of each of these inputs as
-well as the values of the resistors used for division is left to the
-motherboard manufacturers, so you will have to document yourself and edit
-sensors.conf accordingly. National Semiconductor has a document with
-recommended resistor values for some voltages, but this still leaves much
-room for per motherboard specificities, unfortunately. Even worse,
-motherboard manufacturers don't seem to care about National Semiconductor's
-recommendations.
-
-Each voltage measured has associated low and high limits, each of which
-triggers an alarm when crossed.
-
-When available, VID inputs are used to provide the nominal CPU Core voltage.
-The driver will default to VRM 9.0, but this can be changed from user-space.
-The chipsets can handle two sets of VID inputs (on dual-CPU systems), but
-the driver will only export one for now. This may change later if there is
-a need.
-
-
-General Remarks
----------------
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that all hardware registers are read whenever any
-data is read (unless it is less than 2 seconds since the last update, in
-which case cached values are returned instead). As a consequence, when
-a once-only alarm triggers, it may take 2 seconds for it to show, and 2
-more seconds for it to disappear.
-
-Monitoring of in9 isn't enabled at lower init levels (<3) because that
-channel measures the battery voltage (Vbat). It is a known fact that
-repeatedly sampling the battery voltage reduces its lifetime. National
-Semiconductor smartly designed their chipset so that in9 is sampled only
-once every 1024 sampling cycles (that is every 34 minutes at the default
-sampling rate), so the effect is attenuated, but still present.
-
-
-Limitations
------------
-
-The datasheets suggests that some values (fan mins, fan dividers)
-shouldn't be changed once the monitoring has started, but we ignore that
-recommendation. We'll reconsider if it actually causes trouble.

-Kernel driver pc87427
-=====================
-
-Supported chips:
-  * National Semiconductor PC87427
-    Prefix: 'pc87427'
-    Addresses scanned: none, address read from Super I/O config space
-    Datasheet: No longer available
-
-Author: Jean Delvare <jdelvare@suse.de>
-
-Thanks to Amir Habibi at Candelis for setting up a test system, and to
-Michael Kress for testing several iterations of this driver.
-
-
-Description
------------
-
-The National Semiconductor Super I/O chip includes complete hardware
-monitoring capabilities. It can monitor up to 18 voltages, 8 fans and
-6 temperature sensors. Only the fans and temperatures are supported at
-the moment, voltages aren't.
-
-This chip also has fan controlling features (up to 4 PWM outputs),
-which are partly supported by this driver.
-
-The driver assumes that no more than one chip is present, which seems
-reasonable.
-
-
-Fan Monitoring
---------------
-
-Fan rotation speeds are reported as 14-bit values from a gated clock
-signal. Speeds down to 83 RPM can be measured.
-
-An alarm is triggered if the rotation speed drops below a programmable
-limit. Another alarm is triggered if the speed is too low to be measured
-(including stalled or missing fan).
-
-
-Fan Speed Control
------------------
-
-Fan speed can be controlled by PWM outputs. There are 4 possible modes:
-always off, always on, manual and automatic. The latter isn't supported
-by the driver: you can only return to that mode if it was the original
-setting, and the configuration interface is missing.
-
-
-Temperature Monitoring
-----------------------
-
-The PC87427 relies on external sensors (following the SensorPath
-standard), so the resolution and range depend on the type of sensor
-connected. The integer part can be 8-bit or 9-bit, and can be signed or
-not. I couldn't find a way to figure out the external sensor data
-temperature format, so user-space adjustment (typically by a factor 2)
-may be required.

-Description
------------
-
-The PCF8591 is an 8-bit A/D and D/A converter (4 analog inputs and one
-analog output) for the I2C bus produced by Philips Semiconductors (now NXP).
-It is designed to provide a byte I2C interface to up to 4 separate devices.
-
-The PCF8591 has 4 analog inputs programmable as single-ended or
-differential inputs :
-- mode 0 : four single ended inputs
-        Pins AIN0 to AIN3 are single ended inputs for channels 0 to 3
-
-- mode 1 : three differential inputs
-        Pins AIN3 is the common negative differential input
-        Pins AIN0 to AIN2 are positive differential inputs for channels 0 to 2
-
-- mode 2 : single ended and differential mixed
-        Pins AIN0 and AIN1 are single ended inputs for channels 0 and 1
-        Pins AIN2 is the positive differential input for channel 3
-        Pins AIN3 is the negative differential input for channel 3
-
-- mode 3 : two differential inputs
-        Pins AIN0 is the positive differential input for channel 0
-        Pins AIN1 is the negative differential input for channel 0
-        Pins AIN2 is the positive differential input for channel 1
-        Pins AIN3 is the negative differential input for channel 1

-
-* input_mode int
-
-    Analog input mode:
-         0 = four single ended inputs
-         1 = three differential inputs
-         2 = single ended and differential mixed
-         3 = two differential inputs
-
-
-Accessing PCF8591 via /sys interface
--------------------------------------
-
-The PCF8591 is plainly impossible to detect! Thus the driver won't even

-address (in the interval [0x48..0x4f]) either through platform data, or
-using the sysfs interface. See Documentation/i2c/instantiating-devices
-for details.
-
-Directories are being created for each instantiated PCF8591:
-
-/sys/bus/i2c/devices/<0>-<1>/
-where <0> is the bus the chip is connected to (e. g. i2c-0)
-and <1> the chip address ([48..4f])
-
-Inside these directories, there are such files:
-in0_input, in1_input, in2_input, in3_input, out0_enable, out0_output, name
-
-Name contains chip name.
-
-The in0_input, in1_input, in2_input and in3_input files are RO. Reading gives
-the value of the corresponding channel. Depending on the current analog inputs
-configuration, files in2_input and in3_input may not exist. Values range
-from 0 to 255 for single ended inputs and -128 to +127 for differential inputs
-(8-bit ADC).
-
-The out0_enable file is RW. Reading gives "1" for analog output enabled and
-"0" for analog output disabled. Writing accepts "0" and "1" accordingly.
-
-The out0_output file is RW. Writing a number between 0 and 255 (8-bit DAC), send
-the value to the digital-to-analog converter. Note that a voltage will
-only appears on AOUT pin if aout0_enable equals 1. Reading returns the last
-value written.

-
-
-Description
------------
-
-This driver supports hardware monitoring for various PMBus compliant devices.
-It supports voltage, current, power, and temperature sensors as supported
-by the device.
-
-Each monitored channel has its own high and low limits, plus a critical
-limit.
-
-Fan support will be added in a later version of this driver.
-
-
-Usage Notes
------------
-
-This driver does not probe for PMBus devices, since there is no register
-which can be safely used to identify the chip (The MFG_ID register is not
-supported by all chips), and since there is no well defined address range for
-PMBus devices. You will have to instantiate the devices explicitly.
-
-Example: the following will load the driver for an LTC2978 at address 0x60
-on I2C bus #1:
-$ modprobe pmbus
-$ echo ltc2978 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
-
-
-Platform data support
----------------------
-
-Support for additional PMBus chips can be added by defining chip parameters in
-a new chip specific driver file. For example, (untested) code to add support for
-Emerson DS1200 power modules might look as follows.
-
-static struct pmbus_driver_info ds1200_info = {
-	.pages = 1,
-	/* Note: All other sensors are in linear mode */
-	.direct[PSC_VOLTAGE_OUT] = true,
-	.direct[PSC_TEMPERATURE] = true,
-	.direct[PSC_CURRENT_OUT] = true,
-	.m[PSC_VOLTAGE_IN] = 1,
-	.b[PSC_VOLTAGE_IN] = 0,
-	.R[PSC_VOLTAGE_IN] = 3,
-	.m[PSC_VOLTAGE_OUT] = 1,
-	.b[PSC_VOLTAGE_OUT] = 0,
-	.R[PSC_VOLTAGE_OUT] = 3,
-	.m[PSC_TEMPERATURE] = 1,
-	.b[PSC_TEMPERATURE] = 0,
-	.R[PSC_TEMPERATURE] = 3,
-	.func[0] = PMBUS_HAVE_VIN | PMBUS_HAVE_IIN | PMBUS_HAVE_STATUS_INPUT
-		   | PMBUS_HAVE_VOUT | PMBUS_HAVE_STATUS_VOUT
-		   | PMBUS_HAVE_IOUT | PMBUS_HAVE_STATUS_IOUT

-		   | PMBUS_HAVE_TEMP | PMBUS_HAVE_STATUS_TEMP
-		   | PMBUS_HAVE_FAN12 | PMBUS_HAVE_STATUS_FAN12,
-};
-

-			const struct i2c_device_id *id)
-{
-	return pmbus_do_probe(client, id, &ds1200_info);

-

-{

-	{"ds1200", 0},
-	{}
-};
-
-MODULE_DEVICE_TABLE(i2c, ds1200_id);
-
-/* This is the driver that will be inserted */
-static struct i2c_driver ds1200_driver = {
-	.driver = {
-		   .name = "ds1200",
-		   },
-	.probe = ds1200_probe,
-	.remove = ds1200_remove,
-	.id_table = ds1200_id,

-{
-	i2c_del_driver(&ds1200_driver);
-}
-
-
-Sysfs entries
--------------
-
-When probing the chip, the driver identifies which PMBus registers are
-supported, and determines available sensors from this information.
-Attribute files only exist if respective sensors are supported by the chip.
-Labels are provided to inform the user about the sensor associated with
-a given sysfs entry.
-
-The following attributes are supported. Limits are read-write; all other
-attributes are read-only.
-

-PMBus core driver and internal API
-==================================

-Introduction
-============
-
-[from pmbus.org] The Power Management Bus (PMBus) is an open standard
-power-management protocol with a fully defined command language that facilitates
-communication with power converters and other devices in a power system. The
-protocol is implemented over the industry-standard SMBus serial interface and
-enables programming, control, and real-time monitoring of compliant power
-conversion products. This flexible and highly versatile standard allows for
-communication between devices based on both analog and digital technologies, and
-provides true interoperability which will reduce design complexity and shorten
-time to market for power system designers. Pioneered by leading power supply and
-semiconductor companies, this open power system standard is maintained and
-promoted by the PMBus Implementers Forum (PMBus-IF), comprising 30+ adopters
-with the objective to provide support to, and facilitate adoption among, users.
-
-Unfortunately, while PMBus commands are standardized, there are no mandatory
-commands, and manufacturers can add as many non-standard commands as they like.
-Also, different PMBUs devices act differently if non-supported commands are
-executed. Some devices return an error, some devices return 0xff or 0xffff and
-set a status error flag, and some devices may simply hang up.
-
-Despite all those difficulties, a generic PMBus device driver is still useful
-and supported since kernel version 2.6.39. However, it was necessary to support
-device specific extensions in addition to the core PMBus driver, since it is
-simply unknown what new device specific functionality PMBus device developers
-come up with next.
-
-To make device specific extensions as scalable as possible, and to avoid having
-to modify the core PMBus driver repeatedly for new devices, the PMBus driver was
-split into core, generic, and device specific code. The core code (in
-pmbus_core.c) provides generic functionality. The generic code (in pmbus.c)
-provides support for generic PMBus devices. Device specific code is responsible
-for device specific initialization and, if needed, maps device specific
-functionality into generic functionality. This is to some degree comparable
-to PCI code, where generic code is augmented as needed with quirks for all kinds
-of devices.
-
-PMBus device capabilities auto-detection
-========================================
-
-For generic PMBus devices, code in pmbus.c attempts to auto-detect all supported
-PMBus commands. Auto-detection is somewhat limited, since there are simply too
-many variables to consider. For example, it is almost impossible to autodetect
-which PMBus commands are paged and which commands are replicated across all
-pages (see the PMBus specification for details on multi-page PMBus devices).
-
-For this reason, it often makes sense to provide a device specific driver if not
-all commands can be auto-detected. The data structures in this driver can be
-used to inform the core driver about functionality supported by individual
-chips.
-
-Some commands are always auto-detected. This applies to all limit commands
-(lcrit, min, max, and crit attributes) as well as associated alarm attributes.
-Limits and alarm attributes are auto-detected because there are simply too many
-possible combinations to provide a manual configuration interface.
-
-PMBus internal API
-==================
-
-The API between core and device specific PMBus code is defined in
-drivers/hwmon/pmbus/pmbus.h. In addition to the internal API, pmbus.h defines
-standard PMBus commands and virtual PMBus commands.
-
-Standard PMBus commands
------------------------
-
-Standard PMBus commands (commands values 0x00 to 0xff) are defined in the PMBUs
-specification.
-
-Virtual PMBus commands
-----------------------
-
-Virtual PMBus commands are provided to enable support for non-standard
-functionality which has been implemented by several chip vendors and is thus
-desirable to support.
-
-Virtual PMBus commands start with command value 0x100 and can thus easily be
-distinguished from standard PMBus commands (which can not have values larger
-than 0xff). Support for virtual PMBus commands is device specific and thus has
-to be implemented in device specific code.
-
-Virtual commands are named PMBUS_VIRT_xxx and start with PMBUS_VIRT_BASE. All
-virtual commands are word sized.
-
-There are currently two types of virtual commands.
-
-- READ commands are read-only; writes are either ignored or return an error.
-- RESET commands are read/write. Reading reset registers returns zero
-  (used for detection), writing any value causes the associated history to be
-  reset.
-
-Virtual commands have to be handled in device specific driver code. Chip driver
-code returns non-negative values if a virtual command is supported, or a
-negative error code if not. The chip driver may return -ENODATA or any other
-Linux error code in this case, though an error code other than -ENODATA is
-handled more efficiently and thus preferred. Either case, the calling PMBus
-core code will abort if the chip driver returns an error code when reading
-or writing virtual registers (in other words, the PMBus core code will never
-send a virtual command to a chip).
-
-PMBus driver information
-------------------------
-
-PMBus driver information, defined in struct pmbus_driver_info, is the main means
-for device specific drivers to pass information to the core PMBus driver.
-Specifically, it provides the following information.
-
-- For devices supporting its data in Direct Data Format, it provides coefficients
-  for converting register values into normalized data. This data is usually
-  provided by chip manufacturers in device datasheets.
-- Supported chip functionality can be provided to the core driver. This may be
-  necessary for chips which react badly if non-supported commands are executed,
-  and/or to speed up device detection and initialization.
-- Several function entry points are provided to support overriding and/or
-  augmenting generic command execution. This functionality can be used to map
-  non-standard PMBus commands to standard commands, or to augment standard
-  command return values with device specific information.
-
-  API functions
-  -------------
-
-  Functions provided by chip driver
-  ---------------------------------
-
-  All functions return the command return value (read) or zero (write) if
-  successful. A return value of -ENODATA indicates that there is no manufacturer
-  specific command, but that a standard PMBus command may exist. Any other
-  negative return value indicates that the commands does not exist for this
-  chip, and that no attempt should be made to read or write the standard
-  command.
-
-  As mentioned above, an exception to this rule applies to virtual commands,
-  which  _must_ be handled in driver specific code. See "Virtual PMBus Commands"
-  above for more details.
-
-  Command execution in the core PMBus driver code is as follows.
-
-	if (chip_access_function) {
-		status = chip_access_function();
-		if (status != -ENODATA)
-			return status;
-	}
-	if (command >= PMBUS_VIRT_BASE)	/* For word commands/registers only */
-		return -EINVAL;
-	return generic_access();
-
-  Chip drivers may provide pointers to the following functions in struct
-  pmbus_driver_info. All functions are optional.
-
-  int (*read_byte_data)(struct i2c_client *client, int page, int reg);
-
-  Read byte from page <page>, register <reg>.
-  <page> may be -1, which means "current page".
-
-  int (*read_word_data)(struct i2c_client *client, int page, int reg);
-
-  Read word from page <page>, register <reg>.
-
-  int (*write_word_data)(struct i2c_client *client, int page, int reg,
-		         u16 word);
-
-  Write word to page <page>, register <reg>.
-
-  int (*write_byte)(struct i2c_client *client, int page, u8 value);
-
-  Write byte to page <page>, register <reg>.
-  <page> may be -1, which means "current page".
-
-  int (*identify)(struct i2c_client *client, struct pmbus_driver_info *info);
-
-  Determine supported PMBus functionality. This function is only necessary
-  if a chip driver supports multiple chips, and the chip functionality is not
-  pre-determined. It is currently only used by the generic pmbus driver
-  (pmbus.c).
-
-  Functions exported by core driver
-  ---------------------------------
-
-  Chip drivers are expected to use the following functions to read or write
-  PMBus registers. Chip drivers may also use direct I2C commands. If direct I2C
-  commands are used, the chip driver code must not directly modify the current
-  page, since the selected page is cached in the core driver and the core driver
-  will assume that it is selected. Using pmbus_set_page() to select a new page
-  is mandatory.
-
-  int pmbus_set_page(struct i2c_client *client, u8 page);
-
-  Set PMBus page register to <page> for subsequent commands.
-
-  int pmbus_read_word_data(struct i2c_client *client, u8 page, u8 reg);
-
-  Read word data from <page>, <reg>. Similar to i2c_smbus_read_word_data(), but
-  selects page first.
-
-  int pmbus_write_word_data(struct i2c_client *client, u8 page, u8 reg,
-			    u16 word);
-
-  Write word data to <page>, <reg>. Similar to i2c_smbus_write_word_data(), but
-  selects page first.
-
-  int pmbus_read_byte_data(struct i2c_client *client, int page, u8 reg);
-
-  Read byte data from <page>, <reg>. Similar to i2c_smbus_read_byte_data(), but
-  selects page first. <page> may be -1, which means "current page".
-
-  int pmbus_write_byte(struct i2c_client *client, int page, u8 value);
-
-  Write byte data to <page>, <reg>. Similar to i2c_smbus_write_byte(), but
-  selects page first. <page> may be -1, which means "current page".
-
-  void pmbus_clear_faults(struct i2c_client *client);
-
-  Execute PMBus "Clear Fault" command on all chip pages.
-  This function calls the device specific write_byte function if defined.
-  Therefore, it must _not_ be called from that function.
-
-  bool pmbus_check_byte_register(struct i2c_client *client, int page, int reg);
-
-  Check if byte register exists. Return true if the register exists, false
-  otherwise.
-  This function calls the device specific write_byte function if defined to
-  obtain the chip status. Therefore, it must _not_ be called from that function.
-
-  bool pmbus_check_word_register(struct i2c_client *client, int page, int reg);
-
-  Check if word register exists. Return true if the register exists, false
-  otherwise.
-  This function calls the device specific write_byte function if defined to
-  obtain the chip status. Therefore, it must _not_ be called from that function.
-
-  int pmbus_do_probe(struct i2c_client *client, const struct i2c_device_id *id,
-                     struct pmbus_driver_info *info);
-
-  Execute probe function. Similar to standard probe function for other drivers,
-  with the pointer to struct pmbus_driver_info as additional argument. Calls
-  identify function if supported. Must only be called from device probe
-  function.
-
-  void pmbus_do_remove(struct i2c_client *client);
-
-  Execute driver remove function. Similar to standard driver remove function.
-
-  const struct pmbus_driver_info
-	*pmbus_get_driver_info(struct i2c_client *client);
-
-  Return pointer to struct pmbus_driver_info as passed to pmbus_do_probe().

-PMBus driver platform data
-==========================
-
-PMBus platform data is defined in include/linux/pmbus.h. Platform data
-currently only provides a flag field with a single bit used.
-
-#define PMBUS_SKIP_STATUS_CHECK (1 << 0)
-
-struct pmbus_platform_data {
-        u32 flags;              /* Device specific flags */
-};
-

-
-PMBUS_SKIP_STATUS_CHECK
-
-During register detection, skip checking the status register for
-communication or command errors.
-
-Some PMBus chips respond with valid data when trying to read an unsupported
-register. For such chips, checking the status register is mandatory when
-trying to determine if a chip register exists or not.
-Other PMBus chips don't support the STATUS_CML register, or report
-communication errors for no explicable reason. For such chips, checking the
-status register must be disabled.
-
-Some i2c controllers do not support single-byte commands (write commands with

+==================================
+PMBus core driver and internal API
+==================================
+
+Introduction
+============
+
+[from pmbus.org] The Power Management Bus (PMBus) is an open standard
+power-management protocol with a fully defined command language that facilitates
+communication with power converters and other devices in a power system. The
+protocol is implemented over the industry-standard SMBus serial interface and
+enables programming, control, and real-time monitoring of compliant power
+conversion products. This flexible and highly versatile standard allows for
+communication between devices based on both analog and digital technologies, and
+provides true interoperability which will reduce design complexity and shorten
+time to market for power system designers. Pioneered by leading power supply and
+semiconductor companies, this open power system standard is maintained and
+promoted by the PMBus Implementers Forum (PMBus-IF), comprising 30+ adopters
+with the objective to provide support to, and facilitate adoption among, users.
+
+Unfortunately, while PMBus commands are standardized, there are no mandatory
+commands, and manufacturers can add as many non-standard commands as they like.
+Also, different PMBUs devices act differently if non-supported commands are
+executed. Some devices return an error, some devices return 0xff or 0xffff and
+set a status error flag, and some devices may simply hang up.
+
+Despite all those difficulties, a generic PMBus device driver is still useful
+and supported since kernel version 2.6.39. However, it was necessary to support
+device specific extensions in addition to the core PMBus driver, since it is
+simply unknown what new device specific functionality PMBus device developers
+come up with next.
+
+To make device specific extensions as scalable as possible, and to avoid having
+to modify the core PMBus driver repeatedly for new devices, the PMBus driver was
+split into core, generic, and device specific code. The core code (in
+pmbus_core.c) provides generic functionality. The generic code (in pmbus.c)
+provides support for generic PMBus devices. Device specific code is responsible
+for device specific initialization and, if needed, maps device specific
+functionality into generic functionality. This is to some degree comparable
+to PCI code, where generic code is augmented as needed with quirks for all kinds
+of devices.

+
+For this reason, it often makes sense to provide a device specific driver if not

+
+PMBus internal API
+==================
+
+The API between core and device specific PMBus code is defined in
+drivers/hwmon/pmbus/pmbus.h. In addition to the internal API, pmbus.h defines
+standard PMBus commands and virtual PMBus commands.
+
+Standard PMBus commands
+-----------------------
+
+Standard PMBus commands (commands values 0x00 to 0xff) are defined in the PMBUs
+specification.
+
+Virtual PMBus commands
+----------------------
+
+Virtual PMBus commands are provided to enable support for non-standard
+functionality which has been implemented by several chip vendors and is thus

+
+- READ commands are read-only; writes are either ignored or return an error.

+API functions
+=============
+
+Functions provided by chip driver
+---------------------------------
+
+All functions return the command return value (read) or zero (write) if
+successful. A return value of -ENODATA indicates that there is no manufacturer
+specific command, but that a standard PMBus command may exist. Any other
+negative return value indicates that the commands does not exist for this
+chip, and that no attempt should be made to read or write the standard
+command.
+
+As mentioned above, an exception to this rule applies to virtual commands,
+which *must* be handled in driver specific code. See "Virtual PMBus Commands"
+above for more details.
+
+Command execution in the core PMBus driver code is as follows::
+
+	if (chip_access_function) {
+		status = chip_access_function();
+		if (status != -ENODATA)
+			return status;
+	}
+	if (command >= PMBUS_VIRT_BASE)	/* For word commands/registers only */
+		return -EINVAL;
+	return generic_access();
+
+Chip drivers may provide pointers to the following functions in struct
+pmbus_driver_info. All functions are optional.
+
+::
+
+  int (*read_byte_data)(struct i2c_client *client, int page, int reg);
+
+Read byte from page <page>, register <reg>.
+<page> may be -1, which means "current page".
+
+
+::
+
+  int (*read_word_data)(struct i2c_client *client, int page, int reg);
+
+Read word from page <page>, register <reg>.
+
+::
+

+
+  int (*write_byte)(struct i2c_client *client, int page, u8 value);
+
+Write byte to page <page>, register <reg>.
+<page> may be -1, which means "current page".
+
+::
+
+  int (*identify)(struct i2c_client *client, struct pmbus_driver_info *info);
+
+Determine supported PMBus functionality. This function is only necessary
+if a chip driver supports multiple chips, and the chip functionality is not
+pre-determined. It is currently only used by the generic pmbus driver
+(pmbus.c).
+
+Functions exported by core driver

+
+Chip drivers are expected to use the following functions to read or write

+Description
+-----------
+
+This driver supports hardware monitoring for various PMBus compliant devices.
+It supports voltage, current, power, and temperature sensors as supported
+by the device.
+
+Each monitored channel has its own high and low limits, plus a critical
+limit.
+
+Fan support will be added in a later version of this driver.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices, since there is no register
+which can be safely used to identify the chip (The MFG_ID register is not
+supported by all chips), and since there is no well defined address range for
+PMBus devices. You will have to instantiate the devices explicitly.
+
+Example: the following will load the driver for an LTC2978 at address 0x60
+on I2C bus #1::
+
+	$ modprobe pmbus
+	$ echo ltc2978 0x60 > /sys/bus/i2c/devices/i2c-1/new_device
+
+
+Platform data support
+---------------------
+
+Support for additional PMBus chips can be added by defining chip parameters in
+a new chip specific driver file. For example, (untested) code to add support for
+Emerson DS1200 power modules might look as follows::
+
+  static struct pmbus_driver_info ds1200_info = {
+	.pages = 1,
+	/* Note: All other sensors are in linear mode */
+	.direct[PSC_VOLTAGE_OUT] = true,
+	.direct[PSC_TEMPERATURE] = true,
+	.direct[PSC_CURRENT_OUT] = true,
+	.m[PSC_VOLTAGE_IN] = 1,
+	.b[PSC_VOLTAGE_IN] = 0,
+	.R[PSC_VOLTAGE_IN] = 3,
+	.m[PSC_VOLTAGE_OUT] = 1,
+	.b[PSC_VOLTAGE_OUT] = 0,
+	.R[PSC_VOLTAGE_OUT] = 3,
+	.m[PSC_TEMPERATURE] = 1,
+	.b[PSC_TEMPERATURE] = 0,
+	.R[PSC_TEMPERATURE] = 3,
+	.func[0] = PMBUS_HAVE_VIN | PMBUS_HAVE_IIN | PMBUS_HAVE_STATUS_INPUT
+		   | PMBUS_HAVE_VOUT | PMBUS_HAVE_STATUS_VOUT
+		   | PMBUS_HAVE_IOUT | PMBUS_HAVE_STATUS_IOUT
+		   | PMBUS_HAVE_PIN | PMBUS_HAVE_POUT
+		   | PMBUS_HAVE_TEMP | PMBUS_HAVE_STATUS_TEMP
+		   | PMBUS_HAVE_FAN12 | PMBUS_HAVE_STATUS_FAN12,
+  };
+
+  static int ds1200_probe(struct i2c_client *client,
+			  const struct i2c_device_id *id)
+  {
+	return pmbus_do_probe(client, id, &ds1200_info);
+  }
+
+  static int ds1200_remove(struct i2c_client *client)
+  {
+	return pmbus_do_remove(client);
+  }
+
+  static const struct i2c_device_id ds1200_id[] = {
+	{"ds1200", 0},
+	{}
+  };
+
+  MODULE_DEVICE_TABLE(i2c, ds1200_id);
+
+  /* This is the driver that will be inserted */
+  static struct i2c_driver ds1200_driver = {
+	.driver = {
+		   .name = "ds1200",
+		   },
+	.probe = ds1200_probe,
+	.remove = ds1200_remove,
+	.id_table = ds1200_id,
+  };
+
+  static int __init ds1200_init(void)
+  {
+	return i2c_add_driver(&ds1200_driver);
+  }
+
+  static void __exit ds1200_exit(void)
+  {
+	i2c_del_driver(&ds1200_driver);
+  }
+
+
+Sysfs entries
+-------------
+
+When probing the chip, the driver identifies which PMBus registers are
+supported, and determines available sensors from this information.
+Attribute files only exist if respective sensors are supported by the chip.
+Labels are provided to inform the user about the sensor associated with
+a given sysfs entry.
+
+The following attributes are supported. Limits are read-write; all other
+attributes are read-only.

-Description
------------
-
-The SHT10, SHT11, SHT15, SHT71, and SHT75 are humidity and temperature
-sensors.
-
-The devices communicate using two GPIO lines.
-
-Supported resolutions for the measurements are 14 bits for temperature and 12
-bits for humidity, or 12 bits for temperature and 8 bits for humidity.
-
-The humidity calibration coefficients are programmed into an OTP memory on the
-chip. These coefficients are used to internally calibrate the signals from the
-sensors. Disabling the reload of those coefficients allows saving 10ms for each
-measurement and decrease power consumption, while losing on precision.
-
-Some options may be set via sysfs attributes.
-
-Notes:
-  * The regulator supply name is set to "vcc".
-  * If a CRC validation fails, a soft reset command is sent, which resets
-    status register to its hardware default value, but the driver will try to
-    restore the previous device configuration.
-
-Platform data
--------------
-
-* checksum:
-  set it to true to enable CRC validation of the readings (default to false).
-* no_otp_reload:
-  flag to indicate not to reload from OTP (default to false).
-* low_resolution:
-  flag to indicate the temp/humidity resolution to use (default to false).
-
-Sysfs interface
----------------
-
-* temp1_input:     temperature input
-* humidity1_input: humidity input
-* heater_enable:   write 1 in this attribute to enable the on-chip heater,
-                   0 to disable it. Be careful not to enable the heater
-                   for too long.
-* temp1_fault:     if 1, this means that the voltage is low (below 2.47V) and
-                   measurement may be invalid.
-* humidity1_fault: same as temp1_fault.

-
-The SHT21 and SHT25 are humidity and temperature sensors in a DFN package of
-only 3 x 3 mm footprint and 1.1 mm height. The difference between the two

-0.3 degree Celsius).
-
-The devices communicate with the I2C protocol. All sensors are set to the same

-
-The driver uses the default resolution settings of 12 bit for humidity and 14
-bit for temperature, which results in typical measurement times of 22 ms for
-humidity and 66 ms for temperature. To keep self heating below 0.1 degree
-Celsius, the device should not be active for more than 10% of the time,
-e.g. maximum two measurements per second at the given resolution.

-
-Description
------------
-
-This driver implements support for the Sensirion SHT3x-DIS chip, a humidity
-and temperature sensor. Temperature is measured in degrees celsius, relative
-humidity is expressed as a percentage. In the sysfs interface, all values are
-scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
-
-The device communicates with the I2C protocol. Sensors can have the I2C
-addresses 0x44 or 0x45, depending on the wiring. See
-Documentation/i2c/instantiating-devices for methods to instantiate the device.
-
-There are two options configurable by means of sht3x_platform_data:
-1. blocking (pull the I2C clock line down while performing the measurement) or
-   non-blocking mode. Blocking mode will guarantee the fastest result but
-   the I2C bus will be busy during that time. By default, non-blocking mode
-   is used. Make sure clock-stretching works properly on your device if you
-   want to use blocking mode.
-2. high or low accuracy. High accuracy is used by default and using it is
-   strongly recommended.
-
-The sht3x sensor supports a single shot mode as well as 5 periodic measure
-modes, which can be controlled with the update_interval sysfs interface.
-The allowed update_interval in milliseconds are as follows:
-  *     0   single shot mode
-  *  2000   0.5 Hz periodic measurement
-  *  1000   1   Hz periodic measurement
-  *   500   2   Hz periodic measurement
-  *   250   4   Hz periodic measurement
-  *   100  10   Hz periodic measurement
-
-In the periodic measure mode, the sensor automatically triggers a measurement
-with the configured update interval on the chip. When a temperature or humidity
-reading exceeds the configured limits, the alert attribute is set to 1 and
-the alert pin on the sensor is set to high.
-When the temperature and humidity readings move back between the hysteresis
-values, the alert bit is set to 0 and the alert pin on the sensor is set to
-low.

+chip, which has the same electrical interface.
+
+The device communicates with the I2C protocol. All sensors are set to I2C
+address 0x70. See Documentation/i2c/instantiating-devices for methods to
+instantiate the device.
+
+There are two options configurable by means of shtc1_platform_data:
+
+1. blocking (pull the I2C clock line down while performing the measurement) or
+   non-blocking mode. Blocking mode will guarantee the fastest result but
+   the I2C bus will be busy during that time. By default, non-blocking mode
+   is used. Make sure clock-stretching works properly on your device if you
+   want to use blocking mode.
+2. high or low accuracy. High accuracy is used by default and using it is
+   strongly recommended.

-Description
------------
-
-The SiS5595 southbridge has integrated hardware monitor functions. It also
-has an I2C bus, but this driver only supports the hardware monitor. For the
-I2C bus driver see i2c-sis5595.
-
-The SiS5595 implements zero or one temperature sensor, two fan speed
-sensors, four or five voltage sensors, and alarms.
-
-On the first version of the chip, there are four voltage sensors and one
-temperature sensor.
-
-On the second version of the chip, the temperature sensor (temp) and the
-fifth voltage sensor (in4) share a pin which is configurable, but not
-through the driver. Sorry. The driver senses the configuration of the pin,
-which was hopefully set by the BIOS.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the max is crossed; it is also triggered when it drops below the min
-value. Measurements are guaranteed between -55 and +125 degrees, with a
-resolution of 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts. An
-alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution of
-0.016 volt.
-
-In addition to the alarms described above, there is a BTI alarm, which gets
-triggered when an external chip has crossed its limits. Usually, this is
-connected to some LM75-like chip; if at least one crosses its limits, this
-bit gets set.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 1.5
-seconds since the last update). This means that you can easily miss
-once-only alarms.
-
-The SiS5595 only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-Problems
---------
-Some chips refuse to be enabled. We don't know why.
-The driver will recognize this and print a message in dmesg.

-Module Parameters
------------------
-
-* vref: int
-  Default: 1250 (mV)
-  Reference voltage on VREF_ADC pin in mV. It should not be necessary to set
-  this parameter unless a non-default reference voltage is used.
-
-
-Description
------------
-
-[From datasheet] The SMM665 is an Active DC Output power supply Controller
-that monitors, margins and cascade sequences power. The part monitors six
-power supply channels as well as VDD, 12V input, two general-purpose analog
-inputs and an internal temperature sensor using a 10-bit ADC.
-
-Each monitored channel has its own high and low limits, plus a critical
-limit.
-
-Support for SMM465, SMM764, and SMM766 has been implemented but is untested.
-
-
-Usage Notes
------------
-
-This driver does not probe for devices, since there is no register which
-can be safely used to identify the chip. You will have to instantiate
-the devices explicitly. When instantiating the device, you have to specify
-its configuration register address.
-
-Example: the following will load the driver for an SMM665 at address 0x57
-on I2C bus #1:
-$ modprobe smm665
-$ echo smm665 0x57 > /sys/bus/i2c/devices/i2c-1/new_device
-
-
-Sysfs entries
--------------
-
-This driver uses the values in the datasheet to convert ADC register values
-into the values specified in the sysfs-interface document. All attributes are
-read only.
-
-Min, max, lcrit, and crit values are used by the chip to trigger external signals
-and/or other activity. Triggered signals can include HEALTHY, RST, Power Off,
-or Fault depending on the chip configuration. The driver reports values as lcrit
-or crit if exceeding the limits triggers RST, Power Off, or Fault, and as min or
-max otherwise. For details please see the SMM665 datasheet.
-
-For SMM465 and SMM764, values for Channel E and F are reported but undefined.

-Methods for detecting the HP SIO and reading the thermal data on a dc7100.
-
-The thermal information on the dc7100 is contained in the SIO Hardware Monitor
-(HWM). The information is accessed through an index/data pair. The index/data
-pair is located at the HWM Base Address + 0 and the HWM Base Address + 1. The
-HWM Base address can be obtained from Logical Device 8, registers 0x60 (MSB)
-and 0x61 (LSB). Currently we are using 0x480 for the HWM Base Address and
-0x480 and 0x481 for the index/data pair.
-
-Reading temperature information.
-The temperature information is located in the following registers:
-Temp1		0x25	(Currently, this reflects the CPU temp on all systems).
-Temp2		0x26
-Temp3		0x27
-Temp4		0x80
-
-Programming Example
-The following is an example of how to read the HWM temperature registers:
-MOV	DX,480H
-MOV	AX,25H
-OUT	DX,AL
-MOV	DX,481H
-IN	AL,DX
-
-AL contains the data in hex, the temperature in Celsius is the decimal
-equivalent.
-
-Ex: If AL contains 0x2A, the temperature is 42 degrees C.
-
-Reading tach information.
-The fan speed information is located in the following registers:
-		LSB	MSB
-Tach1		0x28	0x29	(Currently, this reflects the CPU
-				fan speed on all systems).
-Tach2		0x2A	0x2B
-Tach3		0x2C	0x2D
-Tach4		0x2E	0x2F
-
-Important!!!
-Reading the tach LSB locks the tach MSB.
-The LSB Must be read first.
-
-How to convert the tach reading to RPM.
-The tach reading (TCount) is given by: (Tach MSB * 256) + (Tach LSB)
-The SIO counts the number of 90kHz (11.111us) pulses per revolution.
-RPM = 60/(TCount * 11.111us)
-
-Example:
-Reg 0x28 = 0x9B
-Reg 0x29 = 0x08
-
-TCount = 0x89B = 2203
-
-RPM = 60 / (2203 * 11.11111 E-6) = 2451 RPM
-
-Obtaining the SIO version.
-
-CONFIGURATION SEQUENCE
-To program the configuration registers, the following sequence must be followed:
-1. Enter Configuration Mode
-2. Configure the Configuration Registers
-3. Exit Configuration Mode.
-
-Enter Configuration Mode
-To place the chip into the Configuration State The config key (0x55) is written
-to the CONFIG PORT (0x2E).
-
-Configuration Mode
-In configuration mode, the INDEX PORT is located at the CONFIG PORT address and
-the DATA PORT is at INDEX PORT address + 1.
-
-The desired configuration registers are accessed in two steps:
-a.	Write the index of the Logical Device Number Configuration Register
-	(i.e., 0x07) to the INDEX PORT and then write the number of the
-	desired logical device to the DATA PORT.
-
-b.	Write the address of the desired configuration register within the
-	logical device to the INDEX PORT and then write or read the config-
-	uration register through the DATA PORT.
-
-Note: If accessing the Global Configuration Registers, step (a) is not required.
-
-Exit Configuration Mode
-To exit the Configuration State the write 0xAA to the CONFIG PORT (0x2E).
-The chip returns to the RUN State.  (This is important).
-
-Programming Example
-The following is an example of how to read the SIO Device ID located at 0x20
-
-; ENTER CONFIGURATION MODE
-MOV	DX,02EH
-MOV	AX,055H
-OUT	DX,AL
-; GLOBAL CONFIGURATION  REGISTER

-; READ THE DATA
-MOV	DX,02FH
-IN	AL,DX
-; EXIT CONFIGURATION MODE
-MOV	DX,02EH
-MOV	AX,0AAH
-OUT	DX,AL
-
-The registers of interest for identifying the SIO on the dc7100 are Device ID
-(0x20) and Device Rev  (0x21).
-
-The Device ID will read 0x6F (0x81 for SCH5307-NS, and 0x85 for SCH5317)
-The Device Rev currently reads 0x01

-Description
------------
-
-The Standard Microsystems Corporation (SMSC) 47M1xx Super I/O chips
-contain monitoring and PWM control circuitry for two fans.
-
-The LPC47M15x, LPC47M192 and LPC47M292 chips contain a full 'hardware
-monitoring block' in addition to the fan monitoring and control. The
-hardware monitoring block is not supported by this driver, use the
-smsc47m192 driver for that.
-
-No documentation is available for the 47M997, but it has the same device
-ID as the 47M15x and 47M192 chips and seems to be compatible.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-PWM values are from 0 to 255.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.

-Description
------------
-
-This driver implements support for the hardware sensor capabilities
-of the SMSC LPC47M192 and compatible Super-I/O chips.
-
-These chips support 3 temperature channels and 8 voltage inputs
-as well as CPU voltage VID input.
-
-They do also have fan monitoring and control capabilities, but the
-these features are accessed via ISA bus and are not supported by this
-driver. Use the 'smsc47m1' driver for fan monitoring and control.
-
-Voltages and temperatures are measured by an 8-bit ADC, the resolution
-of the temperatures is 1 bit per degree C.
-Voltages are scaled such that the nominal voltage corresponds to
-192 counts, i.e. 3/4 of the full range. Thus the available range for
-each voltage channel is 0V ... 255/192*(nominal voltage), the resolution
-is 1 bit per (nominal voltage)/192.
-Both voltage and temperature values are scaled by 1000, the sys files
-show voltages in mV and temperatures in units of 0.001 degC.
-
-The +12V analog voltage input channel (in4_input) is multiplexed with
-bit 4 of the encoded CPU voltage. This means that you either get
-a +12V voltage measurement or a 5 bit CPU VID, but not both.
-The default setting is to use the pin as 12V input, and use only 4 bit VID.
-This driver assumes that the information in the configuration register
-is correct, i.e. that the BIOS has updated the configuration if
-the motherboard has this input wired to VID4.
-
-The temperature and voltage readings are updated once every 1.5 seconds.
-Reading them more often repeats the same values.
-

-in0_input	- +2.5V voltage input
-in1_input	- CPU voltage input (nominal 2.25V)
-in2_input	- +3.3V voltage input
-in3_input	- +5V voltage input
-in4_input	- +12V voltage input (may be missing if used as VID4)
-in5_input	- Vcc voltage input (nominal 3.3V)
-		  This is the supply voltage of the sensor chip itself.
-in6_input	- +1.5V voltage input
-in7_input	- +1.8V voltage input
-
-in[0-7]_min,
-in[0-7]_max	- lower and upper alarm thresholds for in[0-7]_input reading
-
-		  All voltages are read and written in mV.
-
-in[0-7]_alarm	- alarm flags for voltage inputs
-		  These files read '1' in case of alarm, '0' otherwise.
-
-temp1_input	- chip temperature measured by on-chip diode
-temp[2-3]_input	- temperature measured by external diodes (one of these would
-		  typically be wired to the diode inside the CPU)
-
-temp[1-3]_min,
-temp[1-3]_max	- lower and upper alarm thresholds for temperatures
-
-temp[1-3]_offset - temperature offset registers
-		  The chip adds the offsets stored in these registers to
-		  the corresponding temperature readings.
-		  Note that temp1 and temp2 offsets share the same register,
-		  they cannot both be different from zero at the same time.
-		  Writing a non-zero number to one of them will reset the other
-		  offset to zero.
-
-		  All temperatures and offsets are read and written in
-		  units of 0.001 degC.
-
-temp[1-3]_alarm - alarm flags for temperature inputs, '1' in case of alarm,
-		  '0' otherwise.
-temp[2-3]_input_fault - diode fault flags for temperature inputs 2 and 3.

+
+Description
+-----------
+
+This driver implements support for the hardware sensor capabilities
+of the SMSC LPC47M192 and compatible Super-I/O chips.
+
+These chips support 3 temperature channels and 8 voltage inputs
+as well as CPU voltage VID input.
+
+They do also have fan monitoring and control capabilities, but the
+these features are accessed via ISA bus and are not supported by this
+driver. Use the 'smsc47m1' driver for fan monitoring and control.
+
+Voltages and temperatures are measured by an 8-bit ADC, the resolution
+of the temperatures is 1 bit per degree C.
+Voltages are scaled such that the nominal voltage corresponds to
+192 counts, i.e. 3/4 of the full range. Thus the available range for
+each voltage channel is 0V ... 255/192*(nominal voltage), the resolution
+is 1 bit per (nominal voltage)/192.
+Both voltage and temperature values are scaled by 1000, the sys files
+show voltages in mV and temperatures in units of 0.001 degC.
+
+The +12V analog voltage input channel (in4_input) is multiplexed with
+bit 4 of the encoded CPU voltage. This means that you either get
+a +12V voltage measurement or a 5 bit CPU VID, but not both.
+The default setting is to use the pin as 12V input, and use only 4 bit VID.
+This driver assumes that the information in the configuration register
+is correct, i.e. that the BIOS has updated the configuration if
+the motherboard has this input wired to VID4.
+
+The temperature and voltage readings are updated once every 1.5 seconds.
+Reading them more often repeats the same values.

+Description
+-----------
+
+The Standard Microsystems Corporation (SMSC) 47M1xx Super I/O chips
+contain monitoring and PWM control circuitry for two fans.
+
+The LPC47M15x, LPC47M192 and LPC47M292 chips contain a full 'hardware
+monitoring block' in addition to the fan monitoring and control. The
+hardware monitoring block is not supported by this driver, use the
+smsc47m192 driver for that.
+
+No documentation is available for the 47M997, but it has the same device
+ID as the 47M15x and 47M192 chips and seems to be compatible.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+PWM values are from 0 to 255.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.

-	How to Get Your Patch Accepted Into the Hwmon Subsystem
-	-------------------------------------------------------
-
-This text is a collection of suggestions for people writing patches or
-drivers for the hwmon subsystem. Following these suggestions will greatly
-increase the chances of your change being accepted.
-
-
-1. General
-----------
-
-* It should be unnecessary to mention, but please read and follow
-    Documentation/process/submit-checklist.rst
-    Documentation/process/submitting-drivers.rst
-    Documentation/process/submitting-patches.rst
-    Documentation/process/coding-style.rst
-
-* Please run your patch through 'checkpatch --strict'. There should be no
-  errors, no warnings, and few if any check messages. If there are any
-  messages, please be prepared to explain.
-
-* If your patch generates checkpatch errors, warnings, or check messages,
-  please refrain from explanations such as "I prefer that coding style".
-  Keep in mind that each unnecessary message helps hiding a real problem,
-  and a consistent coding style makes it easier for others to understand
-  and review the code.
-
-* Please test your patch thoroughly. We are not your test group.
-  Sometimes a patch can not or not completely be tested because of missing
-  hardware. In such cases, you should test-build the code on at least one
-  architecture. If run-time testing was not achieved, it should be written
-  explicitly below the patch header.
-
-* If your patch (or the driver) is affected by configuration options such as
-  CONFIG_SMP, make sure it compiles for all configuration variants.
-
-
-2. Adding functionality to existing drivers
--------------------------------------------
-
-* Make sure the documentation in Documentation/hwmon/<driver_name> is up to
-  date.
-
-* Make sure the information in Kconfig is up to date.
-
-* If the added functionality requires some cleanup or structural changes, split
-  your patch into a cleanup part and the actual addition. This makes it easier
-  to review your changes, and to bisect any resulting problems.
-
-* Never mix bug fixes, cleanup, and functional enhancements in a single patch.
-
-
-3. New drivers
---------------
-
-* Running your patch or driver file(s) through checkpatch does not mean its
-  formatting is clean. If unsure about formatting in your new driver, run it
-  through Lindent. Lindent is not perfect, and you may have to do some minor
-  cleanup, but it is a good start.
-
-* Consider adding yourself to MAINTAINERS.
-
-* Document the driver in Documentation/hwmon/<driver_name>.
-
-* Add the driver to Kconfig and Makefile in alphabetical order.
-
-* Make sure that all dependencies are listed in Kconfig.
-
-* Please list include files in alphabetic order.
-
-* Please align continuation lines with '(' on the previous line.
-
-* Avoid forward declarations if you can. Rearrange the code if necessary.
-
-* Avoid macros to generate groups of sensor attributes. It not only confuses
-  checkpatch, but also makes it more difficult to review the code.
-
-* Avoid calculations in macros and macro-generated functions. While such macros
-  may save a line or so in the source, it obfuscates the code and makes code
-  review more difficult. It may also result in code which is more complicated
-  than necessary. Use inline functions or just regular functions instead.
-
-* Limit the number of kernel log messages. In general, your driver should not
-  generate an error message just because a runtime operation failed. Report
-  errors to user space instead, using an appropriate error code. Keep in mind
-  that kernel error log messages not only fill up the kernel log, but also are
-  printed synchronously, most likely with interrupt disabled, often to a serial
-  console. Excessive logging can seriously affect system performance.
-
-* Use devres functions whenever possible to allocate resources. For rationale
-  and supported functions, please see Documentation/driver-model/devres.txt.
-  If a function is not supported by devres, consider using devm_add_action().
-
-* If the driver has a detect function, make sure it is silent. Debug messages
-  and messages printed after a successful detection are acceptable, but it
-  must not print messages such as "Chip XXX not found/supported".
-
-  Keep in mind that the detect function will run for all drivers supporting an
-  address if a chip is detected on that address. Unnecessary messages will just
-  pollute the kernel log and not provide any value.
-
-* Provide a detect function if and only if a chip can be detected reliably.
-
-* Only the following I2C addresses shall be probed: 0x18-0x1f, 0x28-0x2f,
-  0x48-0x4f, 0x58, 0x5c, 0x73 and 0x77. Probing other addresses is strongly
-  discouraged as it is known to cause trouble with other (non-hwmon) I2C
-  chips. If your chip lives at an address which can't be probed then the
-  device will have to be instantiated explicitly (which is always better
-  anyway.)
-
-* Avoid writing to chip registers in the detect function. If you have to write,
-  only do it after you have already gathered enough data to be certain that the
-  detection is going to be successful.
-
-  Keep in mind that the chip might not be what your driver believes it is, and
-  writing to it might cause a bad misconfiguration.
-
-* Make sure there are no race conditions in the probe function. Specifically,
-  completely initialize your chip and your driver first, then register with
-  the hwmon subsystem.
-
-* Use devm_hwmon_device_register_with_groups() or, if your driver needs a remove
-  function, hwmon_device_register_with_groups() to register your driver with the
-  hwmon subsystem. Try using devm_add_action() instead of a remove function if
-  possible. Do not use hwmon_device_register().
-
-* Your driver should be buildable as module. If not, please be prepared to
-  explain why it has to be built into the kernel.
-
-* Do not provide support for deprecated sysfs attributes.
-
-* Do not create non-standard attributes unless really needed. If you have to use
-  non-standard attributes, or you believe you do, discuss it on the mailing list
-  first. Either case, provide a detailed explanation why you need the
-  non-standard attribute(s).
-  Standard attributes are specified in Documentation/hwmon/sysfs-interface.
-
-* When deciding which sysfs attributes to support, look at the chip's
-  capabilities. While we do not expect your driver to support everything the
-  chip may offer, it should at least support all limits and alarms.
-
-* Last but not least, please check if a driver for your chip already exists
-  before starting to write a new driver. Especially for temperature sensors,
-  new chips are often variants of previously released chips. In some cases,
-  a presumably new chip may simply have been relabeled.

-Naming and data format standards for sysfs files
-------------------------------------------------
-
-The libsensors library offers an interface to the raw sensors data
-through the sysfs interface. Since lm-sensors 3.0.0, libsensors is
-completely chip-independent. It assumes that all the kernel drivers
-implement the standard sysfs interface described in this document.
-This makes adding or updating support for any given chip very easy, as
-libsensors, and applications using it, do not need to be modified.
-This is a major improvement compared to lm-sensors 2.
-
-Note that motherboards vary widely in the connections to sensor chips.
-There is no standard that ensures, for example, that the second
-temperature sensor is connected to the CPU, or that the second fan is on
-the CPU. Also, some values reported by the chips need some computation
-before they make full sense. For example, most chips can only measure
-voltages between 0 and +4V. Other voltages are scaled back into that
-range using external resistors. Since the values of these resistors
-can change from motherboard to motherboard, the conversions cannot be
-hard coded into the driver and have to be done in user space.
-
-For this reason, even if we aim at a chip-independent libsensors, it will
-still require a configuration file (e.g. /etc/sensors.conf) for proper
-values conversion, labeling of inputs and hiding of unused inputs.
-
-An alternative method that some programs use is to access the sysfs
-files directly. This document briefly describes the standards that the
-drivers follow, so that an application program can scan for entries and
-access this data in a simple and consistent way. That said, such programs
-will have to implement conversion, labeling and hiding of inputs. For
-this reason, it is still not recommended to bypass the library.
-
-Each chip gets its own directory in the sysfs /sys/devices tree.  To
-find all sensor chips, it is easier to follow the device symlinks from
-/sys/class/hwmon/hwmon*.
-
-Up to lm-sensors 3.0.0, libsensors looks for hardware monitoring attributes
-in the "physical" device directory. Since lm-sensors 3.0.1, attributes found
-in the hwmon "class" device directory are also supported. Complex drivers
-(e.g. drivers for multifunction chips) may want to use this possibility to
-avoid namespace pollution. The only drawback will be that older versions of
-libsensors won't support the driver in question.
-
-All sysfs values are fixed point numbers.
-
-There is only one value per file, unlike the older /proc specification.
-The common scheme for files naming is: <type><number>_<item>. Usual
-types for sensor chips are "in" (voltage), "temp" (temperature) and
-"fan" (fan). Usual items are "input" (measured value), "max" (high
-threshold, "min" (low threshold). Numbering usually starts from 1,
-except for voltages which start from 0 (because most data sheets use
-this). A number is always used for elements that can be present more
-than once, even if there is a single element of the given type on the
-specific chip. Other files do not refer to a specific element, so
-they have a simple name, and no number.
-
-Alarms are direct indications read from the chips. The drivers do NOT
-make comparisons of readings to thresholds. This allows violations
-between readings to be caught and alarmed. The exact definition of an
-alarm (for example, whether a threshold must be met or must be exceeded
-to cause an alarm) is chip-dependent.
-
-When setting values of hwmon sysfs attributes, the string representation of
-the desired value must be written, note that strings which are not a number
-are interpreted as 0! For more on how written strings are interpreted see the
-"sysfs attribute writes interpretation" section at the end of this file.

-*********************
-* Global attributes *
-*********************
-
-name		The chip name.
-		This should be a short, lowercase string, not containing
-		whitespace, dashes, or the wildcard character '*'.
-		This attribute represents the chip name. It is the only
-		mandatory attribute.
-		I2C devices get this attribute created automatically.
-		RO
-
-update_interval	The interval at which the chip will update readings.
-		Unit: millisecond
-		RW
-		Some devices have a variable update rate or interval.
-		This attribute can be used to change it to the desired value.

-
-in[0-*]_min	Voltage min value.
-		Unit: millivolt
-		RW
-		
-in[0-*]_lcrit	Voltage critical min value.
-		Unit: millivolt
-		RW
-		If voltage drops to or below this limit, the system may

-
-in[0-*]_max	Voltage max value.
-		Unit: millivolt
-		RW
-		
-in[0-*]_crit	Voltage critical max value.
-		Unit: millivolt

-		least, it should report a fault.
-
-in[0-*]_input	Voltage input value.
-		Unit: millivolt
-		RO
-		Voltage measured on the chip pin.
-		Actual voltage depends on the scaling resistors on the
-		motherboard, as recommended in the chip datasheet.
-		This varies by chip and by motherboard.
-		Because of this variation, values are generally NOT scaled
-		by the chip driver, and must be done by the application.
-		However, some drivers (notably lm87 and via686a)
-		do scale, because of internal resistors built into a chip.
-		These drivers will output the actual voltage. Rule of
-		thumb: drivers should report the voltage values at the
-		"pins" of the chip.
-
-in[0-*]_average

-		Unit: millivolt
-		RO
-
-in[0-*]_lowest

-		Unit: millivolt
-		RO
-		Not always correct.
-
-vrm		Voltage Regulator Module version number. 
-		RW (but changing it should no more be necessary)
-		Originally the VRM standard version multiplied by 10, but now
-		an arbitrary number, as not all standards have a version
-		number.
-		Affects the way the driver calculates the CPU core reference

-		RO
-
-fan[1-*]_div	Fan divisor.
-		Integer value in powers of two (1, 2, 4, 8, 16, 32, 64, 128).
-		RW
-		Some chips only support values 1, 2, 4 and 8.
-		Note that this is actually an internal clock divisor, which
-		affects the measurable speed range, not the read value.
-
-fan[1-*]_pulses	Number of tachometer pulses per fan revolution.
-		Integer value, typically between 1 and 4.
-		RW
-		This value is a characteristic of the fan connected to the
-		device's input, so it has to be set in accordance with the fan
-		model.
-		Should only be created if the chip has a register to configure
-		the number of pulses. In the absence of such a register (and
-		thus attribute) the value assumed by all devices is 2 pulses
-		per fan revolution.
-
-fan[1-*]_target
-		Desired fan speed
-		Unit: revolution/min (RPM)
-		RW
-		Only makes sense if the chip supports closed-loop fan speed
-		control based on the measured fan speed.
-
-fan[1-*]_label	Suggested fan channel label.
-		Text string
-		Should only be created if the driver has hints about what
-		this fan channel is being used for, and user-space doesn't.

-
-pwm[1-*]_enable
-		Fan speed control method:
-		0: no fan speed control (i.e. fan at full speed)
-		1: manual fan speed control enabled (using pwm[1-*])
-		2+: automatic fan speed control enabled
-		Check individual chip documentation files for automatic mode
-		details.
-		RW
-
-pwm[1-*]_mode	0: DC mode (direct current)
-		1: PWM mode (pulse-width modulation)
-		RW
-
-pwm[1-*]_freq	Base PWM frequency in Hz.
-		Only possibly available when pwmN_mode is PWM, but not always
-		present even then.
-		RW
-
-pwm[1-*]_auto_channels_temp
-		Select which temperature channels affect this PWM output in
-		auto mode. Bitfield, 1 is temp1, 2 is temp2, 4 is temp3 etc...
-		Which values are possible depend on the chip used.
-		RW
-
-pwm[1-*]_auto_point[1-*]_pwm
-pwm[1-*]_auto_point[1-*]_temp
-pwm[1-*]_auto_point[1-*]_temp_hyst
-		Define the PWM vs temperature curve. Number of trip points is
-		chip-dependent. Use this for chips which associate trip points
-		to PWM output channels.
-		RW
-
-temp[1-*]_auto_point[1-*]_pwm
-temp[1-*]_auto_point[1-*]_temp
-temp[1-*]_auto_point[1-*]_temp_hyst
-		Define the PWM vs temperature curve. Number of trip points is
-		chip-dependent. Use this for chips which associate trip points
-		to temperature channels.
-		RW
-
-There is a third case where trip points are associated to both PWM output
-channels and temperature channels: the PWM values are associated to PWM
-output channels while the temperature values are associated to temperature
-channels. In that case, the result is determined by the mapping between
-temperature inputs and PWM outputs. When several temperature inputs are
-mapped to a given PWM output, this leads to several candidate PWM values.
-The actual result is up to the chip, but in general the highest candidate
-value (fastest fan speed) wins.

-Some chips measure temperature using external thermistors and an ADC, and

-sysfs attribute writes interpretation
--------------------------------------
-
-hwmon sysfs attributes always contain numbers, so the first thing to do is to
-convert the input to a number, there are 2 ways todo this depending whether
-the number can be negative or not:
-unsigned long u = simple_strtoul(buf, NULL, 10);
-long s = simple_strtol(buf, NULL, 10);
-
-With buf being the buffer with the user input being passed by the kernel.
-Notice that we do not use the second argument of strto[u]l, and thus cannot
-tell when 0 is returned, if this was really 0 or is caused by invalid input.
-This is done deliberately as checking this everywhere would add a lot of
-code to the kernel.
-
-Notice that it is important to always store the converted value in an
-unsigned long or long, so that no wrap around can happen before any further
-checking.
-
-After the input string is converted to an (unsigned) long, the value should be
-checked if its acceptable. Be careful with further conversions on the value
-before checking it for validity, as these conversions could still cause a wrap
-around before the check. For example do not multiply the result, and only
-add/subtract if it has been divided before the add/subtract.
-
-What to do if a value is found to be invalid, depends on the type of the
-sysfs attribute that is being set. If it is a continuous setting like a
-tempX_max or inX_max attribute, then the value should be clamped to its
-limits using clamp_val(value, min_limit, max_limit). If it is not continuous
-like for example a tempX_type, then when an invalid value is written,
--EINVAL should be returned.
-
-Example1, temp1_max, register is a signed 8 bit value (-128 - 127 degrees):
-
-	long v = simple_strtol(buf, NULL, 10) / 1000;
-	v = clamp_val(v, -128, 127);
-	/* write v to register */
-
-Example2, fan divider setting, valid values 2, 4 and 8:
-
-	unsigned long v = simple_strtoul(buf, NULL, 10);
-
-	switch (v) {
-	case 2: v = 1; break;
-	case 4: v = 2; break;
-	case 8: v = 3; break;
-	default:
-		return -EINVAL;
-	}
-	/* write v to register */

+Naming and data format standards for sysfs files
+================================================
+
+The libsensors library offers an interface to the raw sensors data
+through the sysfs interface. Since lm-sensors 3.0.0, libsensors is
+completely chip-independent. It assumes that all the kernel drivers
+implement the standard sysfs interface described in this document.
+This makes adding or updating support for any given chip very easy, as
+libsensors, and applications using it, do not need to be modified.
+This is a major improvement compared to lm-sensors 2.
+
+Note that motherboards vary widely in the connections to sensor chips.
+There is no standard that ensures, for example, that the second
+temperature sensor is connected to the CPU, or that the second fan is on
+the CPU. Also, some values reported by the chips need some computation
+before they make full sense. For example, most chips can only measure
+voltages between 0 and +4V. Other voltages are scaled back into that
+range using external resistors. Since the values of these resistors
+can change from motherboard to motherboard, the conversions cannot be
+hard coded into the driver and have to be done in user space.
+
+For this reason, even if we aim at a chip-independent libsensors, it will
+still require a configuration file (e.g. /etc/sensors.conf) for proper
+values conversion, labeling of inputs and hiding of unused inputs.
+
+An alternative method that some programs use is to access the sysfs
+files directly. This document briefly describes the standards that the
+drivers follow, so that an application program can scan for entries and
+access this data in a simple and consistent way. That said, such programs
+will have to implement conversion, labeling and hiding of inputs. For
+this reason, it is still not recommended to bypass the library.
+
+Each chip gets its own directory in the sysfs /sys/devices tree.  To
+find all sensor chips, it is easier to follow the device symlinks from
+`/sys/class/hwmon/hwmon*`.
+
+Up to lm-sensors 3.0.0, libsensors looks for hardware monitoring attributes
+in the "physical" device directory. Since lm-sensors 3.0.1, attributes found
+in the hwmon "class" device directory are also supported. Complex drivers
+(e.g. drivers for multifunction chips) may want to use this possibility to
+avoid namespace pollution. The only drawback will be that older versions of
+libsensors won't support the driver in question.
+
+All sysfs values are fixed point numbers.
+
+There is only one value per file, unlike the older /proc specification.
+The common scheme for files naming is: <type><number>_<item>. Usual
+types for sensor chips are "in" (voltage), "temp" (temperature) and
+"fan" (fan). Usual items are "input" (measured value), "max" (high
+threshold, "min" (low threshold). Numbering usually starts from 1,
+except for voltages which start from 0 (because most data sheets use
+this). A number is always used for elements that can be present more
+than once, even if there is a single element of the given type on the
+specific chip. Other files do not refer to a specific element, so
+they have a simple name, and no number.
+
+Alarms are direct indications read from the chips. The drivers do NOT
+make comparisons of readings to thresholds. This allows violations
+between readings to be caught and alarmed. The exact definition of an
+alarm (for example, whether a threshold must be met or must be exceeded
+to cause an alarm) is chip-dependent.
+
+When setting values of hwmon sysfs attributes, the string representation of
+the desired value must be written, note that strings which are not a number
+are interpreted as 0! For more on how written strings are interpreted see the
+"sysfs attribute writes interpretation" section at the end of this file.

+*****************
+Global attributes
+*****************
+
+`name`
+		The chip name.
+		This should be a short, lowercase string, not containing
+		whitespace, dashes, or the wildcard character '*'.
+		This attribute represents the chip name. It is the only
+		mandatory attribute.
+		I2C devices get this attribute created automatically.
+
+		RO
+
+`update_interval`
+		The interval at which the chip will update readings.
+		Unit: millisecond
+
+		RW
+
+		Some devices have a variable update rate or interval.
+		This attribute can be used to change it to the desired value.

+
+`in[0-*]_min`
+		Voltage min value.
+
+		Unit: millivolt
+
+		RW
+
+`in[0-*]_lcrit`
+		Voltage critical min value.
+
+		Unit: millivolt
+
+		RW
+
+		If voltage drops to or below this limit, the system may
+		take drastic action such as power down or reset. At the very

+
+`in[0-*]_input`
+		Voltage input value.
+
+		Unit: millivolt
+
+		RO
+
+		Voltage measured on the chip pin.
+
+		Actual voltage depends on the scaling resistors on the
+		motherboard, as recommended in the chip datasheet.
+
+		This varies by chip and by motherboard.
+		Because of this variation, values are generally NOT scaled
+		by the chip driver, and must be done by the application.
+		However, some drivers (notably lm87 and via686a)
+		do scale, because of internal resistors built into a chip.
+		These drivers will output the actual voltage. Rule of
+		thumb: drivers should report the voltage values at the
+		"pins" of the chip.

+`vrm`
+		Voltage Regulator Module version number.
+
+		RW (but changing it should no more be necessary)
+
+		Originally the VRM standard version multiplied by 10, but now
+		an arbitrary number, as not all standards have a version

+
+`fan[1-*]_div`
+		Fan divisor.
+

+
+		RW
+
+		Some chips only support values 1, 2, 4 and 8.
+		Note that this is actually an internal clock divisor, which
+		affects the measurable speed range, not the read value.
+
+`fan[1-*]_pulses`
+		Number of tachometer pulses per fan revolution.
+
+		Integer value, typically between 1 and 4.
+
+		RW
+
+		This value is a characteristic of the fan connected to the
+		device's input, so it has to be set in accordance with the fan
+		model.
+
+		Should only be created if the chip has a register to configure
+		the number of pulses. In the absence of such a register (and
+		thus attribute) the value assumed by all devices is 2 pulses
+		per fan revolution.
+
+`fan[1-*]_target`
+		Desired fan speed
+
+		Unit: revolution/min (RPM)
+

+
+`pwm[1-*]`
+		Pulse width modulation fan control.
+
+		Integer value in the range 0 to 255
+
+		RW
+
+		255 is max or 100%.
+
+`pwm[1-*]_enable`
+		Fan speed control method:
+
+		- 0: no fan speed control (i.e. fan at full speed)
+		- 1: manual fan speed control enabled (using `pwm[1-*]`)
+		- 2+: automatic fan speed control enabled
+
+		Check individual chip documentation files for automatic mode

+		Only possibly available when pwmN_mode is PWM, but not always
+		present even then.
+
+		RW
+
+`pwm[1-*]_auto_channels_temp`
+		Select which temperature channels affect this PWM output in
+		auto mode.
+
+		Bitfield, 1 is temp1, 2 is temp2, 4 is temp3 etc...
+		Which values are possible depend on the chip used.
+
+		RW
+
+`pwm[1-*]_auto_point[1-*]_pwm` / `pwm[1-*]_auto_point[1-*]_temp` / `pwm[1-*]_auto_point[1-*]_temp_hyst`
+		Define the PWM vs temperature curve.
+
+		Number of trip points is chip-dependent. Use this for chips
+		which associate trip points to PWM output channels.
+
+		RW
+
+`temp[1-*]_auto_point[1-*]_pwm` / `temp[1-*]_auto_point[1-*]_temp` / `temp[1-*]_auto_point[1-*]_temp_hyst`
+		Define the PWM vs temperature curve.
+
+		Number of trip points is chip-dependent. Use this for chips
+		which associate trip points to temperature channels.
+
+		RW
+
+There is a third case where trip points are associated to both PWM output
+channels and temperature channels: the PWM values are associated to PWM
+output channels while the temperature values are associated to temperature
+channels. In that case, the result is determined by the mapping between
+temperature inputs and PWM outputs. When several temperature inputs are
+mapped to a given PWM output, this leads to several candidate PWM values.
+The actual result is up to the chip, but in general the highest candidate
+value (fastest fan speed) wins.

+sysfs attribute writes interpretation
+-------------------------------------
+
+hwmon sysfs attributes always contain numbers, so the first thing to do is to
+convert the input to a number, there are 2 ways todo this depending whether
+the number can be negative or not::
+
+	unsigned long u = simple_strtoul(buf, NULL, 10);
+	long s = simple_strtol(buf, NULL, 10);
+
+With buf being the buffer with the user input being passed by the kernel.
+Notice that we do not use the second argument of strto[u]l, and thus cannot
+tell when 0 is returned, if this was really 0 or is caused by invalid input.
+This is done deliberately as checking this everywhere would add a lot of
+code to the kernel.
+
+Notice that it is important to always store the converted value in an
+unsigned long or long, so that no wrap around can happen before any further
+checking.
+
+After the input string is converted to an (unsigned) long, the value should be
+checked if its acceptable. Be careful with further conversions on the value
+before checking it for validity, as these conversions could still cause a wrap
+around before the check. For example do not multiply the result, and only
+add/subtract if it has been divided before the add/subtract.
+
+What to do if a value is found to be invalid, depends on the type of the
+sysfs attribute that is being set. If it is a continuous setting like a
+tempX_max or inX_max attribute, then the value should be clamped to its
+limits using clamp_val(value, min_limit, max_limit). If it is not continuous
+like for example a tempX_type, then when an invalid value is written,
+-EINVAL should be returned.
+
+Example1, temp1_max, register is a signed 8 bit value (-128 - 127 degrees)::
+
+	long v = simple_strtol(buf, NULL, 10) / 1000;
+	v = clamp_val(v, -128, 127);
+	/* write v to register */
+
+Example2, fan divider setting, valid values 2, 4 and 8::
+
+	unsigned long v = simple_strtoul(buf, NULL, 10);
+
+	switch (v) {
+	case 2: v = 1; break;
+	case 4: v = 2; break;
+	case 8: v = 3; break;
+	default:
+		return -EINVAL;
+	}
+	/* write v to register */

-
-Description
------------
-This driver implements support for the Microchip TC654 and TC655.
-
-The TC654 uses the 2-wire interface compatible with the SMBUS 2.0
-specification. The TC654 has two (2) inputs for measuring fan RPM and
-one (1) PWM output which can be used for fan control.
-
-Configuration Notes
--------------------
-Ordinarily the pwm1_mode ABI is used for controlling the pwm output
-mode.  However, for this chip the output is always pwm, and the
-pwm1_mode determines if the pwm output is controlled via the pwm1 value
-or via the Vin analog input.
-
-
-Setting pwm1_mode to 1 will cause the pwm output to be driven based on
-the pwm1 value. Setting pwm1_mode to 0 will cause the pwm output to be
-driven based on the Vin input.

-
-Author: Krzysztof Helt <krzysztof.h1@wp.pl>

-
-Credits:

-
-Module Parameters
------------------
-
-* adm1022_temp3: short array
-  List of adapter,address pairs to force chips into ADM1022 mode with
-  second remote temperature. This does not work for original THMC50 chips.
-
-Description
------------
-
-The THMC50 implements: an internal temperature sensor, support for an
-external diode-type temperature sensor (compatible w/ the diode sensor inside
-many processors), and a controllable fan/analog_out DAC. For the temperature
-sensors, limits can be set through the appropriate Overtemperature Shutdown
-register and Hysteresis register. Each value can be set and read to half-degree
-accuracy.  An alarm is issued (usually to a connected LM78) when the
-temperature gets higher then the Overtemperature Shutdown value; it stays on
-until the temperature falls below the Hysteresis value. All temperatures are in
-degrees Celsius, and are guaranteed within a range of -55 to +125 degrees.
-
-The THMC50 only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-The THMC50 is usually used in combination with LM78-like chips, to measure
-the temperature of the processor(s).
-
-The ADM1022 works the same as THMC50 but it is faster (5 Hz instead of
-1 Hz for THMC50). It can be also put in a new mode to handle additional
-remote temperature sensor. The driver use the mode set by BIOS by default.
-
-In case the BIOS is broken and the mode is set incorrectly, you can force
-the mode with additional remote temperature with adm1022_temp3 parameter.
-A typical symptom of wrong setting is a fan forced to full speed.
-
-Driver Features
----------------
-
-The driver provides up to three temperatures:
-
-temp1		-- internal
-temp2		-- remote
-temp3		-- 2nd remote only for ADM1022
-
-pwm1		-- fan speed (0 = stop, 255 = full)
-pwm1_mode	-- always 0 (DC mode)
-
-The value of 0 for pwm1 also forces FAN_OFF signal from the chip,
-so it stops fans even if the value 0 into the ANALOG_OUT register does not.
-
-The driver was tested on Compaq AP550 with two ADM1022 chips (one works
-in the temp3 mode), five temperature readings and two fans.

+The sensor is accurate to 0.75C over the range of -25 to +85 C, and to 1.0
+degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The
+operating temperature has a minimum of -55 C and a maximum of +150 C.
+Hysteresis values can be set to 0, 1, 2, or 4C.
+
+The TMP108 has a programmable update rate that can select between 8, 4, 1, and
+0.5 Hz.
+
+By default the TMP108 reads the temperature continuously. To conserve power,
+the TMP108 has a one-shot mode where the device is normally shut-down. When a
+one shot is requested the temperature is read, the result can be retrieved,
+and then the device is shut down automatically. (This driver only supports
+continuous mode.)
+
+The driver provides the common sysfs-interface for temperatures (see
+Documentation/hwmon/sysfs-interface.rst under Temperatures).

-Description
------------
-
-This driver implements support for Texas Instruments TMP401, TMP411,
-TMP431, TMP432, TMP435, and TMP461 chips. These chips implement one or two
-remote and one local temperature sensors. Temperature is measured in degrees
-Celsius. Resolution of the remote sensor is 0.0625 degree. Local
-sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not
-supported by the driver so far, so using the default resolution of 0.5
-degree).
-
-The driver provides the common sysfs-interface for temperatures (see
-Documentation/hwmon/sysfs-interface under Temperatures).
-
-The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides
-some additional features.
-
-* Minimum and Maximum temperature measured since power-on, chip-reset
-
-  Exported via sysfs attributes tempX_lowest and tempX_highest.
-
-* Reset of historical minimum/maximum temperature measurements
-
-  Exported via sysfs attribute temp_reset_history. Writing 1 to this
-  file triggers a reset.
-
-TMP432 is compatible with TMP401 and TMP431. It supports two external
-temperature sensors.
-
-TMP461 is compatible with TMP401. It supports offset correction
-that is applied to the remote sensor.
-

-Introduction
-------------
-
-Most mainboards have sensor chips to monitor system health (like temperatures,
-voltages, fans speed). They are often connected through an I2C bus, but some
-are also connected directly through the ISA bus.
-
-The kernel drivers make the data from the sensor chips available in the /sys
-virtual filesystem. Userspace tools are then used to display the measured
-values or configure the chips in a more friendly manner.
-
-Lm-sensors
-----------
-
-Core set of utilities that will allow you to obtain health information,
-setup monitoring limits etc. You can get them on their homepage
-http://www.lm-sensors.org/ or as a package from your Linux distribution.
-
-If from website:
-Get lm-sensors from project web site. Please note, you need only userspace
-part, so compile with "make user" and install with "make user_install".
-
-General hints to get things working:
-
-0) get lm-sensors userspace utils
-1) compile all drivers in I2C and Hardware Monitoring sections as modules
-   in your kernel
-2) run sensors-detect script, it will tell you what modules you need to load.
-3) load them and run "sensors" command, you should see some results.
-4) fix sensors.conf, labels, limits, fan divisors
-5) if any more problems consult FAQ, or documentation
-
-Other utilities
----------------
-
-If you want some graphical indicators of system health look for applications
-like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
-hardware-monitor

+Userspace tools
+===============
+
+Introduction
+------------
+
+Most mainboards have sensor chips to monitor system health (like temperatures,
+voltages, fans speed). They are often connected through an I2C bus, but some
+are also connected directly through the ISA bus.
+
+The kernel drivers make the data from the sensor chips available in the /sys
+virtual filesystem. Userspace tools are then used to display the measured
+values or configure the chips in a more friendly manner.
+
+Lm-sensors
+----------
+
+Core set of utilities that will allow you to obtain health information,
+setup monitoring limits etc. You can get them on their homepage
+http://www.lm-sensors.org/ or as a package from your Linux distribution.
+
+If from website:
+Get lm-sensors from project web site. Please note, you need only userspace
+part, so compile with "make user" and install with "make user_install".
+
+General hints to get things working:
+
+0) get lm-sensors userspace utils
+1) compile all drivers in I2C and Hardware Monitoring sections as modules
+   in your kernel
+2) run sensors-detect script, it will tell you what modules you need to load.
+3) load them and run "sensors" command, you should see some results.
+4) fix sensors.conf, labels, limits, fan divisors
+5) if any more problems consult FAQ, or documentation
+
+Other utilities
+---------------
+
+If you want some graphical indicators of system health look for applications
+like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
+hardware-monitor
+
+If you are server administrator you can try snmpd or mrtgutils.

-Description
------------
-
-The driver does not distinguish between the chips and reports
-all as a 686A.
-
-The Via 686a southbridge has integrated hardware monitor functionality.
-It also has an I2C bus, but this driver only supports the hardware monitor.
-For the I2C bus driver, see <file:Documentation/i2c/busses/i2c-viapro>
-
-The Via 686a implements three temperature sensors, two fan rotation speed
-sensors, five voltage sensors and alarms.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed; it is triggered again
-as soon as it drops below the hysteresis value.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Voltages are internally scalled, so each voltage channel
-has a different resolution and range.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The driver only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-Known Issues
-------------
-
-This driver handles sensors integrated in some VIA south bridges. It is
-possible that a motherboard maker used a VT82C686A/B chip as part of a
-product design but was not interested in its hardware monitoring features,
-in which case the sensor inputs will not be wired. This is the case of
-the Asus K7V, A7V and A7V133 motherboards, to name only a few of them.
-So, if you need the force_addr parameter, and end up with values which
-don't seem to make any sense, don't look any further: your chip is simply
-not wired for hardware monitoring.

-    Datasheet: Provided by VIA upon request and under NDA
-
-Authors: Juerg Haefliger <juergh@gmail.com>
-
-This driver is based on the driver for kernel 2.4 by Mark D. Studebaker and
-its port to kernel 2.6 by Lars Ekman.
-
-Thanks to Joseph Chan and Fiona Gatt from VIA for providing documentation and
-technical support.
-
-
-Module Parameters
------------------
-
-* uch_config: int	Override the BIOS default universal channel (UCH)
-			configuration for channels 1-5.
-			Legal values are in the range of 0-31. Bit 0 maps to
-			UCH1, bit 1 maps to UCH2 and so on. Setting a bit to 1
-			enables the thermal input of that particular UCH and
-			setting a bit to 0 enables the voltage input.
-
-* int_mode: int		Override the BIOS default temperature interrupt mode.
-			The only possible value is 0 which forces interrupt
-			mode 0. In this mode, any pending interrupt is cleared
-			when the status register is read but is regenerated as
-			long as the temperature stays above the hysteresis
-			limit.
-
-Be aware that overriding BIOS defaults might cause some unwanted side effects!
-
-
-Description
------------
-
-The VIA VT1211 Super-I/O chip includes complete hardware monitoring
-capabilities. It monitors 2 dedicated temperature sensor inputs (temp1 and
-temp2), 1 dedicated voltage (in5) and 2 fans. Additionally, the chip
-implements 5 universal input channels (UCH1-5) that can be individually
-programmed to either monitor a voltage or a temperature.
-
-This chip also provides manual and automatic control of fan speeds (according
-to the datasheet). The driver only supports automatic control since the manual
-mode doesn't seem to work as advertised in the datasheet. In fact I couldn't
-get manual mode to work at all! Be aware that automatic mode hasn't been
-tested very well (due to the fact that my EPIA M10000 doesn't have the fans
-connected to the PWM outputs of the VT1211 :-().
-
-The following table shows the relationship between the vt1211 inputs and the
-sysfs nodes.

-
-Voltage Monitoring
-------------------
-
-Voltages are sampled by an 8-bit ADC with a LSB of ~10mV. The supported input
-range is thus from 0 to 2.60V. Voltage values outside of this range need
-external scaling resistors. This external scaling needs to be compensated for
-via compute lines in sensors.conf, like:
-
-compute inx @*(1+R1/R2), @/(1+R1/R2)
-
-The board level scaling resistors according to VIA's recommendation are as
-follows. And this is of course totally dependent on the actual board
-implementation :-) You will have to find documentation for your own
-motherboard and edit sensors.conf accordingly.
-
-                                      Expected
-Voltage       R1     R2     Divider   Raw Value

-VccP          ---    ---    1.0       1400 mV (1)
-+5V           14K    10K    2.4       2083 mV

-
-(1) Depending on the CPU (1.4V is for a VIA C3 Nehemiah).
-(2) R1 and R2 for 3.3V (int) are internal to the VT1211 chip and the driver
-    performs the scaling and returns the properly scaled voltage value.
-
-Each measured voltage has an associated low and high limit which triggers an
-alarm when crossed.
-
-
-Temperature Monitoring
-----------------------
-
-Temperatures are reported in millidegree Celsius. Each measured temperature
-has a high limit which triggers an alarm if crossed. There is an associated
-hysteresis value with each temperature below which the temperature has to drop
-before the alarm is cleared (this is only true for interrupt mode 0). The
-interrupt mode can be forced to 0 in case the BIOS doesn't do it
-automatically. See the 'Module Parameters' section for details.
-
-All temperature channels except temp2 are external. Temp2 is the VT1211
-internal thermal diode and the driver does all the scaling for temp2 and
-returns the temperature in millidegree Celsius. For the external channels
-temp1 and temp3-temp7, scaling depends on the board implementation and needs
-to be performed in userspace via sensors.conf.
-
-Temp1 is an Intel-type thermal diode which requires the following formula to
-convert between sysfs readings and real temperatures:
-
-compute temp1 (@-Offset)/Gain, (@*Gain)+Offset
-
-According to the VIA VT1211 BIOS porting guide, the following gain and offset
-values should be used:
-
-Diode Type      Offset   Gain
-----------      ------   ----
-Intel CPU       88.638   0.9528
-                65.000   0.9686   *)
-VIA C3 Ezra     83.869   0.9528
-VIA C3 Ezra-T   73.869   0.9528
-
-*) This is the formula from the lm_sensors 2.10.0 sensors.conf file. I don't
-know where it comes from or how it was derived, it's just listed here for
-completeness.
-
-Temp3-temp7 support NTC thermistors. For these channels, the driver returns
-the voltages as seen at the individual pins of UCH1-UCH5. The voltage at the
-pin (Vpin) is formed by a voltage divider made of the thermistor (Rth) and a
-scaling resistor (Rs):
-
-Vpin = 2200 * Rth / (Rs + Rth)   (2200 is the ADC max limit of 2200 mV)
-
-The equation for the thermistor is as follows (google it if you want to know
-more about it):
-
-Rth = Ro * exp(B * (1 / T - 1 / To))   (To is 298.15K (25C) and Ro is the
-                                        nominal resistance at 25C)
-
-Mingling the above two equations and assuming Rs = Ro and B = 3435 yields the
-following formula for sensors.conf:
-
-compute tempx 1 / (1 / 298.15 - (` (2200 / @ - 1)) / 3435) - 273.15,
-              2200 / (1 + (^ (3435 / 298.15 - 3435 / (273.15 + @))))
-
-
-Fan Speed Control
------------------
-
-The VT1211 provides 2 programmable PWM outputs to control the speeds of 2
-fans. Writing a 2 to any of the two pwm[1-2]_enable sysfs nodes will put the
-PWM controller in automatic mode. There is only a single controller that
-controls both PWM outputs but each PWM output can be individually enabled and
-disabled.
-
-Each PWM has 4 associated distinct output duty-cycles: full, high, low and
-off. Full and off are internally hard-wired to 255 (100%) and 0 (0%),
-respectively. High and low can be programmed via
-pwm[1-2]_auto_point[2-3]_pwm. Each PWM output can be associated with a
-different thermal input but - and here's the weird part - only one set of
-thermal thresholds exist that controls both PWMs output duty-cycles. The
-thermal thresholds are accessible via pwm[1-2]_auto_point[1-4]_temp. Note
-that even though there are 2 sets of 4 auto points each, they map to the same
-registers in the VT1211 and programming one set is sufficient (actually only
-the first set pwm1_auto_point[1-4]_temp is writable, the second set is
-read-only).
-
-PWM Auto Point             PWM Output Duty-Cycle
-------------------------------------------------
-pwm[1-2]_auto_point4_pwm   full speed duty-cycle (hard-wired to 255)
-pwm[1-2]_auto_point3_pwm   high speed duty-cycle
-pwm[1-2]_auto_point2_pwm   low speed duty-cycle
-pwm[1-2]_auto_point1_pwm   off duty-cycle (hard-wired to 0)
-
-Temp Auto Point             Thermal Threshold
----------------------------------------------
-pwm[1-2]_auto_point4_temp   full speed temp
-pwm[1-2]_auto_point3_temp   high speed temp
-pwm[1-2]_auto_point2_temp   low speed temp
-pwm[1-2]_auto_point1_temp   off temp
-
-Long story short, the controller implements the following algorithm to set the
-PWM output duty-cycle based on the input temperature:
-
-Thermal Threshold             Output Duty-Cycle
-                    (Rising Temp)           (Falling Temp)
-----------------------------------------------------------

+Kernel driver vt1211
+====================
+
+Supported chips:
+
+  * VIA VT1211
+
+    Prefix: 'vt1211'
+
+    Addresses scanned: none, address read from Super-I/O config space
+
+    Datasheet: Provided by VIA upon request and under NDA
+
+Authors: Juerg Haefliger <juergh@gmail.com>
+
+This driver is based on the driver for kernel 2.4 by Mark D. Studebaker and
+its port to kernel 2.6 by Lars Ekman.
+
+Thanks to Joseph Chan and Fiona Gatt from VIA for providing documentation and
+technical support.
+
+
+Module Parameters
+-----------------
+
+
+* uch_config: int
+			Override the BIOS default universal channel (UCH)
+			configuration for channels 1-5.
+			Legal values are in the range of 0-31. Bit 0 maps to
+			UCH1, bit 1 maps to UCH2 and so on. Setting a bit to 1
+			enables the thermal input of that particular UCH and
+			setting a bit to 0 enables the voltage input.
+
+* int_mode: int
+			Override the BIOS default temperature interrupt mode.
+			The only possible value is 0 which forces interrupt
+			mode 0. In this mode, any pending interrupt is cleared
+			when the status register is read but is regenerated as
+			long as the temperature stays above the hysteresis
+			limit.
+
+Be aware that overriding BIOS defaults might cause some unwanted side effects!
+
+
+Description
+-----------
+
+The VIA VT1211 Super-I/O chip includes complete hardware monitoring
+capabilities. It monitors 2 dedicated temperature sensor inputs (temp1 and
+temp2), 1 dedicated voltage (in5) and 2 fans. Additionally, the chip
+implements 5 universal input channels (UCH1-5) that can be individually
+programmed to either monitor a voltage or a temperature.
+
+This chip also provides manual and automatic control of fan speeds (according
+to the datasheet). The driver only supports automatic control since the manual
+mode doesn't seem to work as advertised in the datasheet. In fact I couldn't
+get manual mode to work at all! Be aware that automatic mode hasn't been
+tested very well (due to the fact that my EPIA M10000 doesn't have the fans
+connected to the PWM outputs of the VT1211 :-().
+
+The following table shows the relationship between the vt1211 inputs and the
+sysfs nodes.

+=============== ============== =========== ================================
+
+
+Voltage Monitoring
+------------------
+
+Voltages are sampled by an 8-bit ADC with a LSB of ~10mV. The supported input
+range is thus from 0 to 2.60V. Voltage values outside of this range need
+external scaling resistors. This external scaling needs to be compensated for
+via compute lines in sensors.conf, like:
+
+compute inx @*(1+R1/R2), @/(1+R1/R2)
+
+The board level scaling resistors according to VIA's recommendation are as
+follows. And this is of course totally dependent on the actual board
+implementation :-) You will have to find documentation for your own
+motherboard and edit sensors.conf accordingly.
+

+
+.. [1] Depending on the CPU (1.4V is for a VIA C3 Nehemiah).
+
+.. [2] R1 and R2 for 3.3V (int) are internal to the VT1211 chip and the driver
+       performs the scaling and returns the properly scaled voltage value.
+
+Each measured voltage has an associated low and high limit which triggers an
+alarm when crossed.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are reported in millidegree Celsius. Each measured temperature
+has a high limit which triggers an alarm if crossed. There is an associated
+hysteresis value with each temperature below which the temperature has to drop
+before the alarm is cleared (this is only true for interrupt mode 0). The
+interrupt mode can be forced to 0 in case the BIOS doesn't do it
+automatically. See the 'Module Parameters' section for details.
+
+All temperature channels except temp2 are external. Temp2 is the VT1211
+internal thermal diode and the driver does all the scaling for temp2 and
+returns the temperature in millidegree Celsius. For the external channels
+temp1 and temp3-temp7, scaling depends on the board implementation and needs
+to be performed in userspace via sensors.conf.
+
+Temp1 is an Intel-type thermal diode which requires the following formula to
+convert between sysfs readings and real temperatures:
+
+compute temp1 (@-Offset)/Gain, (@*Gain)+Offset
+
+According to the VIA VT1211 BIOS porting guide, the following gain and offset
+values should be used:
+
+=============== ======== ===========
+Diode Type      Offset   Gain
+=============== ======== ===========
+Intel CPU       88.638   0.9528
+		65.000   0.9686 [3]_
+VIA C3 Ezra     83.869   0.9528
+VIA C3 Ezra-T   73.869   0.9528
+=============== ======== ===========
+
+.. [3] This is the formula from the lm_sensors 2.10.0 sensors.conf file. I don't
+       know where it comes from or how it was derived, it's just listed here for
+       completeness.
+
+Temp3-temp7 support NTC thermistors. For these channels, the driver returns
+the voltages as seen at the individual pins of UCH1-UCH5. The voltage at the
+pin (Vpin) is formed by a voltage divider made of the thermistor (Rth) and a
+scaling resistor (Rs)::
+
+  Vpin = 2200 * Rth / (Rs + Rth)   (2200 is the ADC max limit of 2200 mV)
+
+The equation for the thermistor is as follows (google it if you want to know
+more about it)::
+
+  Rth = Ro * exp(B * (1 / T - 1 / To))   (To is 298.15K (25C) and Ro is the
+					  nominal resistance at 25C)
+
+Mingling the above two equations and assuming Rs = Ro and B = 3435 yields the
+following formula for sensors.conf::
+
+  compute tempx 1 / (1 / 298.15 - (` (2200 / @ - 1)) / 3435) - 273.15,
+		2200 / (1 + (^ (3435 / 298.15 - 3435 / (273.15 + @))))
+
+
+Fan Speed Control
+-----------------
+
+The VT1211 provides 2 programmable PWM outputs to control the speeds of 2
+fans. Writing a 2 to any of the two pwm[1-2]_enable sysfs nodes will put the
+PWM controller in automatic mode. There is only a single controller that
+controls both PWM outputs but each PWM output can be individually enabled and
+disabled.
+
+Each PWM has 4 associated distinct output duty-cycles: full, high, low and
+off. Full and off are internally hard-wired to 255 (100%) and 0 (0%),
+respectively. High and low can be programmed via
+pwm[1-2]_auto_point[2-3]_pwm. Each PWM output can be associated with a
+different thermal input but - and here's the weird part - only one set of
+thermal thresholds exist that controls both PWMs output duty-cycles. The
+thermal thresholds are accessible via pwm[1-2]_auto_point[1-4]_temp. Note
+that even though there are 2 sets of 4 auto points each, they map to the same
+registers in the VT1211 and programming one set is sufficient (actually only
+the first set pwm1_auto_point[1-4]_temp is writable, the second set is
+read-only).
+
+========================== =========================================
+PWM Auto Point             PWM Output Duty-Cycle
+========================== =========================================
+pwm[1-2]_auto_point4_pwm   full speed duty-cycle (hard-wired to 255)
+pwm[1-2]_auto_point3_pwm   high speed duty-cycle
+pwm[1-2]_auto_point2_pwm   low speed duty-cycle
+pwm[1-2]_auto_point1_pwm   off duty-cycle (hard-wired to 0)
+========================== =========================================
+

+pwm[1-2]_auto_point4_temp   full speed temp

+pwm[1-2]_auto_point2_temp   low speed temp
+pwm[1-2]_auto_point1_temp   off temp
+==========================  =================
+
+Long story short, the controller implements the following algorithm to set the
+PWM output duty-cycle based on the input temperature:
+

-Description
------------
-
-This driver implements support for the Winbond W83627EHF, W83627EHG,
-W83627DHG, W83627DHG-P, W83627UHG, W83667HG, W83667HG-B, W83667HG-I
-(NCT6775F), and NCT6776F super I/O chips. We will refer to them collectively
-as Winbond chips.
-
-The chips implement 3 to 4 temperature sensors (9 for NCT6775F and NCT6776F),
-2 to 5 fan rotation speed sensors, 8 to 10 analog voltage sensors, one VID
-(except for 627UHG), alarms with beep warnings (control unimplemented),
-and some automatic fan regulation strategies (plus manual fan control mode).
-
-The temperature sensor sources on W82677HG-B, NCT6775F, and NCT6776F are
-configurable. temp4 and higher attributes are only reported if its temperature
-source differs from the temperature sources of the already reported temperature
-sensors. The configured source for each of the temperature sensors is provided
-in tempX_label.
-
-Temperatures are measured in degrees Celsius and measurement resolution is 1
-degC for temp1 and and 0.5 degC for temp2 and temp3. For temp4 and higher,
-resolution is 1 degC for W83667HG-B and 0.0 degC for NCT6775F and NCT6776F.
-An alarm is triggered when the temperature gets higher than high limit;
-it stays on until the temperature falls below the hysteresis value.
-Alarms are only supported for temp1, temp2, and temp3.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or
-128) to give the readings more range or accuracy. The driver sets the most
-suitable fan divisor itself. Some fans might not be present because they
-share pins with other functions.
-
-Voltage sensors (also known as IN sensors) report their values in millivolts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit.
-
-The driver supports automatic fan control mode known as Thermal Cruise.
-In this mode, the chip attempts to keep the measured temperature in a
-predefined temperature range. If the temperature goes out of range, fan
-is driven slower/faster to reach the predefined range again.
-
-The mode works for fan1-fan4. Mapping of temperatures to pwm outputs is as
-follows:
-
-temp1 -> pwm1
-temp2 -> pwm2
-temp3 -> pwm3 (not on 627UHG)
-prog  -> pwm4 (not on 667HG and 667HG-B; the programmable setting is not
-	       supported by the driver)
-
-/sys files
-----------
-
-name - this is a standard hwmon device entry, it contains the name of
-       the device (see the prefix in the list of supported devices at
-       the top of this file)
-
-pwm[1-4] - this file stores PWM duty cycle or DC value (fan speed) in range:
-	   0 (stop) to 255 (full)
-
-pwm[1-4]_enable - this file controls mode of fan/temperature control:
-	* 1 Manual mode, write to pwm file any value 0-255 (full speed)
-	* 2 "Thermal Cruise" mode
-	* 3 "Fan Speed Cruise" mode
-	* 4 "Smart Fan III" mode
-	* 5 "Smart Fan IV" mode
-
-	SmartFan III mode is not supported on NCT6776F.
-
-	SmartFan IV mode is configurable only if it was configured at system
-	startup, and is only supported for W83677HG-B, NCT6775F, and NCT6776F.
-	SmartFan IV operational parameters can not be configured at this time,
-	and the various pwm attributes are not used in SmartFan IV mode.
-	The attributes can be written to, which is useful if you plan to
-	configure the system for a different pwm mode. However, the information
-	returned when reading pwm attributes is unrelated to SmartFan IV
-	operation.
-
-pwm[1-4]_mode - controls if output is PWM or DC level
-        * 0 DC output (0 - 12v)
-        * 1 PWM output
-
-Thermal Cruise mode
--------------------
-
-If the temperature is in the range defined by:
-
-pwm[1-4]_target    - set target temperature, unit millidegree Celsius
-		     (range 0 - 127000)
-pwm[1-4]_tolerance - tolerance, unit millidegree Celsius (range 0 - 15000)
-
-there are no changes to fan speed. Once the temperature leaves the interval,
-fan speed increases (temp is higher) or decreases if lower than desired.
-There are defined steps and times, but not exported by the driver yet.
-
-pwm[1-4]_min_output - minimum fan speed (range 1 - 255), when the temperature
-                      is below defined range.
-pwm[1-4]_stop_time  - how many milliseconds [ms] must elapse to switch
-                      corresponding fan off. (when the temperature was below
-                      defined range).
-pwm[1-4]_start_output-minimum fan speed (range 1 - 255) when spinning up
-pwm[1-4]_step_output- rate of fan speed change (1 - 255)
-pwm[1-4]_stop_output- minimum fan speed (range 1 - 255) when spinning down
-pwm[1-4]_max_output - maximum fan speed (range 1 - 255), when the temperature
-                      is above defined range.
-
-Note: last six functions are influenced by other control bits, not yet exported
-      by the driver, so a change might not have any effect.
-
-Implementation Details
-----------------------
-
-Future driver development should bear in mind that the following registers have
-different functions on the 627EHF and the 627DHG. Some registers also have
-different power-on default values, but BIOS should already be loading
-appropriate defaults. Note that bank selection must be performed as is currently
-done in the driver for all register addresses.
-
-0x49:  only on DHG, selects temperature source for AUX fan, CPU fan0
-0x4a:  not completely documented for the EHF and the DHG documentation assigns
-       different behavior to bits 7 and 6, including extending the temperature
-       input selection to SmartFan I, not just SmartFan III. Testing on the EHF
-       will reveal whether they are compatible or not.
-
-0x58:  Chip ID: 0xa1=EHF 0xc1=DHG
-0x5e:  only on DHG, has bits to enable "current mode" temperature detection and
-       critical temperature protection
-0x45b: only on EHF, bit 3, vin4 alarm (EHF supports 10 inputs, only 9 on DHG)
-0x552: only on EHF, vin4
-0x558: only on EHF, vin4 high limit
-0x559: only on EHF, vin4 low limit
-0x6b:  only on DHG, SYS fan critical temperature
-0x6c:  only on DHG, CPU fan0 critical temperature
-0x6d:  only on DHG, AUX fan critical temperature
-0x6e:  only on DHG, CPU fan1 critical temperature
-
-0x50-0x55 and 0x650-0x657 are marked "Test Register" for the EHF, but "Reserved
-       Register" for the DHG
-
-The DHG also supports PECI, where the DHG queries Intel CPU temperatures, and
-the ICH8 southbridge gets that data via PECI from the DHG, so that the
-southbridge drives the fans. And the DHG supports SST, a one-wire serial bus.
-
-The DHG-P has an additional automatic fan speed control mode named Smart Fan
-(TM) III+. This mode is not yet supported by the driver.

+(except for 627UHG), alarms with beep warnings (control unimplemented),
+and some automatic fan regulation strategies (plus manual fan control mode).
+
+The temperature sensor sources on W82677HG-B, NCT6775F, and NCT6776F are
+configurable. temp4 and higher attributes are only reported if its temperature
+source differs from the temperature sources of the already reported temperature
+sensors. The configured source for each of the temperature sensors is provided
+in tempX_label.
+
+Temperatures are measured in degrees Celsius and measurement resolution is 1
+degC for temp1 and and 0.5 degC for temp2 and temp3. For temp4 and higher,
+resolution is 1 degC for W83667HG-B and 0.0 degC for NCT6775F and NCT6776F.
+An alarm is triggered when the temperature gets higher than high limit;
+it stays on until the temperature falls below the hysteresis value.
+Alarms are only supported for temp1, temp2, and temp3.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or
+128) to give the readings more range or accuracy. The driver sets the most
+suitable fan divisor itself. Some fans might not be present because they
+share pins with other functions.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+The driver supports automatic fan control mode known as Thermal Cruise.
+In this mode, the chip attempts to keep the measured temperature in a
+predefined temperature range. If the temperature goes out of range, fan
+is driven slower/faster to reach the predefined range again.
+
+The mode works for fan1-fan4. Mapping of temperatures to pwm outputs is as
+follows::
+
+  temp1 -> pwm1
+  temp2 -> pwm2
+  temp3 -> pwm3 (not on 627UHG)
+  prog  -> pwm4 (not on 667HG and 667HG-B; the programmable setting is not
+		 supported by the driver)
+
+/sys files
+----------
+
+name
+	this is a standard hwmon device entry, it contains the name of
+	the device (see the prefix in the list of supported devices at
+	the top of this file)
+
+pwm[1-4]
+	this file stores PWM duty cycle or DC value (fan speed) in range:
+
+	   0 (stop) to 255 (full)
+
+pwm[1-4]_enable
+	this file controls mode of fan/temperature control:
+
+	* 1 Manual mode, write to pwm file any value 0-255 (full speed)
+	* 2 "Thermal Cruise" mode
+	* 3 "Fan Speed Cruise" mode
+	* 4 "Smart Fan III" mode
+	* 5 "Smart Fan IV" mode
+
+	SmartFan III mode is not supported on NCT6776F.
+
+	SmartFan IV mode is configurable only if it was configured at system
+	startup, and is only supported for W83677HG-B, NCT6775F, and NCT6776F.
+	SmartFan IV operational parameters can not be configured at this time,
+	and the various pwm attributes are not used in SmartFan IV mode.
+	The attributes can be written to, which is useful if you plan to
+	configure the system for a different pwm mode. However, the information
+	returned when reading pwm attributes is unrelated to SmartFan IV
+	operation.
+
+pwm[1-4]_mode
+	controls if output is PWM or DC level
+
+	* 0 DC output (0 - 12v)
+	* 1 PWM output
+
+Thermal Cruise mode
+-------------------
+
+If the temperature is in the range defined by:
+
+pwm[1-4]_target
+		   set target temperature, unit millidegree Celsius
+		   (range 0 - 127000)
+pwm[1-4]_tolerance
+		   tolerance, unit millidegree Celsius (range 0 - 15000)
+
+there are no changes to fan speed. Once the temperature leaves the interval,
+fan speed increases (temp is higher) or decreases if lower than desired.
+There are defined steps and times, but not exported by the driver yet.
+
+pwm[1-4]_min_output
+		   minimum fan speed (range 1 - 255), when the temperature
+		   is below defined range.
+pwm[1-4]_stop_time
+		   how many milliseconds [ms] must elapse to switch
+		   corresponding fan off. (when the temperature was below
+		   defined range).
+pwm[1-4]_start_output
+		   minimum fan speed (range 1 - 255) when spinning up
+pwm[1-4]_step_output
+		   rate of fan speed change (1 - 255)
+pwm[1-4]_stop_output
+		   minimum fan speed (range 1 - 255) when spinning down
+pwm[1-4]_max_output
+		   maximum fan speed (range 1 - 255), when the temperature
+		   is above defined range.
+
+Note: last six functions are influenced by other control bits, not yet exported
+      by the driver, so a change might not have any effect.
+
+Implementation Details
+----------------------
+
+Future driver development should bear in mind that the following registers have
+different functions on the 627EHF and the 627DHG. Some registers also have
+different power-on default values, but BIOS should already be loading
+appropriate defaults. Note that bank selection must be performed as is currently
+done in the driver for all register addresses.

+
+The DHG also supports PECI, where the DHG queries Intel CPU temperatures, and
+the ICH8 southbridge gets that data via PECI from the DHG, so that the
+southbridge drives the fans. And the DHG supports SST, a one-wire serial bus.
+
+The DHG-P has an additional automatic fan speed control mode named Smart Fan
+(TM) III+. This mode is not yet supported by the driver.

-Module Parameters
------------------
-
-* force_i2c: int
-  Initialize the I2C address of the sensors
-* init: int
-  (default is 1)
-  Use 'init=0' to bypass initializing the chip.
-  Try this if your computer crashes when you load the module.
-
-Description
------------
-
-This driver implements support for ISA accesses *only* for
-the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
-We will refer to them collectively as Winbond chips.
-
-This driver supports ISA accesses, which should be more reliable
-than i2c accesses. Also, for Tyan boards which contain both a
-Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
-using this driver will avoid i2c address conflicts and complex
-initialization that were required in the w83781d driver.
-
-If you really want i2c accesses for these Super I/O chips,
-use the w83781d driver. However this is not the preferred method
-now that this ISA driver has been developed.
-
-The w83627_HF_ uses pins 110-106 as VID0-VID4. The w83627_THF_ uses the
-same pins as GPIO[0:4]. Technically, the w83627_THF_ does not support a
-VID reading. However the two chips have the identical 128 pin package. So,
-it is possible or even likely for a w83627thf to have the VID signals routed
-to these pins despite their not being labeled for that purpose. Therefore,
-the w83627thf driver interprets these as VID. If the VID on your board
-doesn't work, first see doc/vid in the lm_sensors package[1]. If that still
-doesn't help, you may just ignore the bogus VID reading with no harm done.
-
-For further information on this driver see the w83781d driver documentation.
-
-[1] http://www.lm-sensors.org/browser/lm-sensors/trunk/doc/vid
-
-Forcing the address
--------------------
-
-The driver used to have a module parameter named force_addr, which could
-be used to force the base I/O address of the hardware monitoring block.
-This was meant as a workaround for mainboards with a broken BIOS. This
-module parameter is gone for technical reasons. If you need this feature,
-you can obtain the same result by using the isaset tool (part of
-lm-sensors) before loading the driver:
-
-# Enter the Super I/O config space
-isaset -y -f 0x2e 0x87
-isaset -y -f 0x2e 0x87
-
-# Select the hwmon logical device
-isaset -y 0x2e 0x2f 0x07 0x0b
-
-# Set the base I/O address (to 0x290 in this example)
-isaset -y 0x2e 0x2f 0x60 0x02
-isaset -y 0x2e 0x2f 0x61 0x90
-
-# Exit the Super-I/O config space
-isaset -y -f 0x2e 0xaa
-
-The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but
-0x4e/0x4f is also possible.
-
-Voltage pin mapping
--------------------
-
-Here is a summary of the voltage pin mapping for the W83627THF. This
-can be useful to convert data provided by board manufacturers into
-working libsensors configuration statements.
-
-    W83627THF		|
-  Pin	| Name		| Register	| Sysfs attribute
------------------------------------------------------
-  100	| CPUVCORE	| 20h		| in0
-   99	| VIN0		| 21h		| in1
-   98	| VIN1		| 22h		| in2
-   97	| VIN2		| 24h		| in4

-   61	| 5VSB		| 50h (bank 5)	| in7
-   74	| VBAT		| 51h (bank 5)	| in8
-
-For other supported devices, you'll have to take the hard path and
-look up the information in the datasheet yourself (and then add it
-to this document please.)

------------------
-
-* init int
-  (default 1)
-  Use 'init=0' to bypass initializing the chip.
-  Try this if your computer crashes when you load the module.
-
-* reset int
-  (default 0)
-  The driver used to reset the chip on load, but does no more. Use
-  'reset=1' to restore the old behavior. Report if you need to do this.
-
-force_subclients=bus,caddr,saddr,saddr
-  This is used to force the i2c addresses for subclients of
-  a certain chip. Typical usage is `force_subclients=0,0x2d,0x4a,0x4b'
-  to force the subclients of chip 0x2d on bus 0 to i2c addresses
-  0x4a and 0x4b. This parameter is useful for certain Tyan boards.
-
-Description
------------
-
-This driver implements support for the Winbond W83781D, W83782D, W83783S
-chips, and the Asus AS99127F chips. We will refer to them collectively as
-W8378* chips.
-
-There is quite some difference between these chips, but they are similar
-enough that it was sensible to put them together in one driver.
-The Asus chips are similar to an I2C-only W83782D.

-
-Detection of these chips can sometimes be foiled because they can be in
-an internal state that allows no clean access. If you know the address
-of the chip, use a 'force' parameter; this will put them into a more
-well-behaved state first.
-
-The W8378* implements temperature sensors (three on the W83781D and W83782D,
-two on the W83783S), three fan rotation speed sensors, voltage sensors
-(seven on the W83781D, nine on the W83782D and six on the W83783S), VID
-lines, alarms with beep warnings, and some miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. There is always one main
-temperature sensor, and one (W83783S) or two (W83781D and W83782D) other
-sensors. An alarm is triggered for the main sensor once when the
-Overtemperature Shutdown limit is crossed; it is triggered again as soon as
-it drops below the Hysteresis value. A more useful behavior
-can be found by setting the Hysteresis value to +127 degrees Celsius; in
-this case, alarms are issued during all the time when the actual temperature
-is above the Overtemperature Shutdown value. The driver sets the
-hysteresis value for temp1 to 127 at initialization.
-
-For the other temperature sensor(s), an alarm is triggered when the
-temperature gets higher then the Overtemperature Shutdown value; it stays
-on until the temperature falls below the Hysteresis value. But on the
-W83781D, there is only one alarm that functions for both other sensors!
-Temperatures are guaranteed within a range of -55 to +125 degrees. The
-main temperature sensors has a resolution of 1 degree; the other sensor(s)
-of 0.5 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8 for the
-W83781D; 1, 2, 4, 8, 16, 32, 64 or 128 for the others) to give
-the readings more range or accuracy. Not all RPM values can accurately
-be represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution
-of 0.016 volt.
-
-The VID lines encode the core voltage value: the voltage level your processor
-should work with. This is hardcoded by the mainboard and/or processor itself.
-It is a value in volts. When it is unconnected, you will often find the
-value 3.50 V here.
-
-The W83782D and W83783S temperature conversion machine understands about
-several kinds of temperature probes. You can program the so-called
-beta value in the sensor files. '1' is the PII/Celeron diode, '2' is the
-TN3904 transistor, and 3435 the default thermistor value. Other values
-are (not yet) supported.
-
-In addition to the alarms described above, there is a CHAS alarm on the
-chips which triggers if your computer case is open.
-
-When an alarm goes off, you can be warned by a beeping signal through
-your computer speaker. It is possible to enable all beeping globally,
-or only the beeping for some alarms.
-
-Individual alarm and beep bits:
-
-0x000001: in0
-0x000002: in1
-0x000004: in2
-0x000008: in3
-0x000010: temp1
-0x000020: temp2 (+temp3 on W83781D)
-0x000040: fan1
-0x000080: fan2
-0x000100: in4
-0x000200: in5
-0x000400: in6
-0x000800: fan3
-0x001000: chassis
-0x002000: temp3 (W83782D only)
-0x010000: in7 (W83782D only)
-0x020000: in8 (W83782D only)
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The chips only update values each 1.5 seconds; reading them more often
-will do no harm, but will return 'old' values.
-
-AS99127F PROBLEMS
------------------
-The as99127f support was developed without the benefit of a datasheet.
-In most cases it is treated as a w83781d (although revision 2 of the
-AS99127F looks more like a w83782d).
-This support will be BETA until a datasheet is released.
-One user has reported problems with fans stopping
-occasionally.
-
-Note that the individual beep bits are inverted from the other chips.
-The driver now takes care of this so that user-space applications
-don't have to know about it.
-
-Known problems:
-	- Problems with diode/thermistor settings (supported?)
-	- One user reports fans stopping under high server load.
-	- Revision 2 seems to have 2 PWM registers but we don't know
-	  how to handle them. More details below.
-
-These will not be fixed unless we get a datasheet.
-If you have problems, please lobby Asus to release a datasheet.
-Unfortunately several others have without success.
-Please do not send mail to us asking for better as99127f support.
-We have done the best we can without a datasheet.
-Please do not send mail to the author or the sensors group asking for
-a datasheet or ideas on how to convince Asus. We can't help.
-
-
-NOTES:
------
-  783s has no in1 so that in[2-6] are compatible with the 781d/782d.
-
-  783s pin is programmable for -5V or temp1; defaults to -5V,
-       no control in driver so temp1 doesn't work.
-
-  782d and 783s datasheets differ on which is pwm1 and which is pwm2.
-       We chose to follow 782d.
-
-  782d and 783s pin is programmable for fan3 input or pwm2 output;
-       defaults to fan3 input.
-       If pwm2 is enabled (with echo 255 1 > pwm2), then
-       fan3 will report 0.
-
-  782d has pwm1-2 for ISA, pwm1-4 for i2c. (pwm3-4 share pins with
-       the ISA pins)
-
-Data sheet updates:

-Answers from Winbond tech support
----------------------------------
->
-> 1) In the W83781D data sheet section 7.2 last paragraph, it talks about
->    reprogramming the R-T table if the Beta of the thermistor is not
->    3435K. The R-T table is described briefly in section 8.20.
->    What formulas do I use to program a new R-T table for a given Beta?
->
-	We are sorry that the calculation for R-T table value is
-confidential. If you have another Beta value of thermistor, we can help
-to calculate the R-T table for you. But you should give us real R-T
-Table which can be gotten by thermistor vendor. Therefore we will calculate
-them and obtain 32-byte data, and you can fill the 32-byte data to the
-register in Bank0.CR51 of W83781D.
-
-
-> 2) In the W83782D data sheet, it mentions that pins 38, 39, and 40 are
->    programmable to be either thermistor or Pentium II diode inputs.
->    How do I program them for diode inputs? I can't find any register
->    to program these to be diode inputs.

-Asus Clones
------------
-
-We have no datasheets for the Asus clones (AS99127F and ASB100 Bach).
-Here are some very useful information that were given to us by Alex Van
-Kaam about how to detect these chips, and how to read their values. He
-also gives advice for another Asus chipset, the Mozart-2 (which we
-don't support yet). Thanks Alex!
-I reworded some parts and added personal comments.
-
-# Detection:
-
-AS99127F rev.1, AS99127F rev.2 and ASB100:
-- I2C address range: 0x29 - 0x2F
-- If register 0x58 holds 0x31 then we have an Asus (either ASB100 or
-  AS99127F)
-- Which one depends on register 0x4F (manufacturer ID):
-  0x06 or 0x94: ASB100
-  0x12 or 0xC3: AS99127F rev.1
-  0x5C or 0xA3: AS99127F rev.2
-  Note that 0x5CA3 is Winbond's ID (WEC), which let us think Asus get their
-  AS99127F rev.2 direct from Winbond. The other codes mean ATT and DVC,
-  respectively. ATT could stand for Asustek something (although it would be
-  very badly chosen IMHO), I don't know what DVC could stand for. Maybe
-  these codes simply aren't meant to be decoded that way.
-
-Mozart-2:
-- I2C address: 0x77
-- If register 0x58 holds 0x56 or 0x10 then we have a Mozart-2
-- Of the Mozart there are 3 types:
-  0x58=0x56, 0x4E=0x94, 0x4F=0x36: Asus ASM58 Mozart-2
-  0x58=0x56, 0x4E=0x94, 0x4F=0x06: Asus AS2K129R Mozart-2
-  0x58=0x10, 0x4E=0x5C, 0x4F=0xA3: Asus ??? Mozart-2
-  You can handle all 3 the exact same way :)
-
-# Temperature sensors:
-
-ASB100:
-- sensor 1: register 0x27
-- sensor 2 & 3 are the 2 LM75's on the SMBus
-- sensor 4: register 0x17
-Remark: I noticed that on Intel boards sensor 2 is used for the CPU
-  and 4 is ignored/stuck, on AMD boards sensor 4 is the CPU and sensor 2 is
-  either ignored or a socket temperature.
-
-AS99127F (rev.1 and 2 alike):
-- sensor 1: register 0x27
-- sensor 2 & 3 are the 2 LM75's on the SMBus
-Remark: Register 0x5b is suspected to be temperature type selector. Bit 1
-  would control temp1, bit 3 temp2 and bit 5 temp3.
-
-Mozart-2:
-- sensor 1: register 0x27
-- sensor 2: register 0x13
-
-# Fan sensors:
-
-ASB100, AS99127F (rev.1 and 2 alike):
-- 3 fans, identical to the W83781D
-
-Mozart-2:
-- 2 fans only, 1350000/RPM/div
-- fan 1: register 0x28,  divisor on register 0xA1 (bits 4-5)
-- fan 2: register 0x29,  divisor on register 0xA1 (bits 6-7)
-
-# Voltages:
-
-This is where there is a difference between AS99127F rev.1 and 2.
-Remark: The difference is similar to the difference between
-  W83781D and W83782D.
-
-ASB100:
-in0=r(0x20)*0.016
-in1=r(0x21)*0.016
-in2=r(0x22)*0.016
-in3=r(0x23)*0.016*1.68

-in5=r(0x25)*(-0.016)*3.97
-in6=r(0x26)*(-0.016)*1.666
-
-AS99127F rev.1:

-in6=r(0x26)*(-0.016)*1.503
-
-AS99127F rev.2:
-in0=r(0x20)*0.016
-in1=r(0x21)*0.016
-in2=r(0x22)*0.016
-in3=r(0x23)*0.016*1.68

-in5=(r(0x25)*0.016-3.6)*5.14+3.6
-in6=(r(0x26)*0.016-3.6)*3.14+3.6
-
-Mozart-2:
-in0=r(0x20)*0.016
-in1=255
-in2=r(0x22)*0.016
-in3=r(0x23)*0.016*1.68

-# PWM
-
-* Additional info about PWM on the AS99127F (may apply to other Asus
-chips as well) by Jean Delvare as of 2004-04-09:
-
-AS99127F revision 2 seems to have two PWM registers at 0x59 and 0x5A,
-and a temperature sensor type selector at 0x5B (which basically means
-that they swapped registers 0x59 and 0x5B when you compare with Winbond
-chips).
-Revision 1 of the chip also has the temperature sensor type selector at
-0x5B, but PWM registers have no effect.
-
-We don't know exactly how the temperature sensor type selection works.
-Looks like bits 1-0 are for temp1, bits 3-2 for temp2 and bits 5-4 for
-temp3, although it is possible that only the most significant bit matters
-each time. So far, values other than 0 always broke the readings.
-
-PWM registers seem to be split in two parts: bit 7 is a mode selector,
-while the other bits seem to define a value or threshold.
-
-When bit 7 is clear, bits 6-0 seem to hold a threshold value. If the value
-is below a given limit, the fan runs at low speed. If the value is above
-the limit, the fan runs at full speed. We have no clue as to what the limit
-represents. Note that there seem to be some inertia in this mode, speed
-changes may need some time to trigger. Also, an hysteresis mechanism is
-suspected since walking through all the values increasingly and then
-decreasingly led to slightly different limits.
-
-When bit 7 is set, bits 3-0 seem to hold a threshold value, while bits 6-4
-would not be significant. If the value is below a given limit, the fan runs
-at full speed, while if it is above the limit it runs at low speed (so this
-is the contrary of the other mode, in a way). Here again, we don't know
-what the limit is supposed to represent.
-
-One remarkable thing is that the fans would only have two or three
-different speeds (transitional states left apart), not a whole range as
-you usually get with PWM.
-
-As a conclusion, you can write 0x00 or 0x8F to the PWM registers to make
-fans run at low speed, and 0x7F or 0x80 to make them run at full speed.
-
-Please contact us if you can figure out how it is supposed to work. As
-long as we don't know more, the w83781d driver doesn't handle PWM on
-AS99127F chips at all.
-
-* Additional info about PWM on the AS99127F rev.1 by Hector Martin:
-
-I've been fiddling around with the (in)famous 0x59 register and
-found out the following values do work as a form of coarse pwm:
-
-0x80 - seems to turn fans off after some time(1-2 minutes)... might be
-some form of auto-fan-control based on temp? hmm (Qfan? this mobo is an
-old ASUS, it isn't marketed as Qfan. Maybe some beta pre-attempt at Qfan
-that was dropped at the BIOS)
-0x81 - off
-0x82 - slightly "on-ner" than off, but my fans do not get to move. I can
-hear the high-pitched PWM sound that motors give off at too-low-pwm.
-0x83 - now they do move. Estimate about 70% speed or so.
-0x84-0x8f - full on
-
-Changing the high nibble doesn't seem to do much except the high bit
-(0x80) must be set for PWM to work, else the current pwm doesn't seem to
-change.
-
-My mobo is an ASUS A7V266-E. This behavior is similar to what I got
-with speedfan under Windows, where 0-15% would be off, 15-2x% (can't
-remember the exact value) would be 70% and higher would be full on.
-
-* Additional info about PWM on the AS99127F rev.1 from lm-sensors
-  ticket #2350:
-
-I conducted some experiment on Asus P3B-F motherboard with AS99127F
-(Ver. 1).
-
-I confirm that 0x59 register control the CPU_Fan Header on this
-motherboard, and 0x5a register control PWR_Fan.
-
-In order to reduce the dependency of specific fan, the measurement is
-conducted with a digital scope without fan connected. I found out that
-P3B-F actually output variable DC voltage on fan header center pin,
-looks like PWM is filtered on this motherboard.
-
-Here are some of measurements:
-
-0x80     20 mV
-0x81     20 mV
-0x82    232 mV
-0x83   1.2  V
-0x84   2.31 V
-0x85   3.44 V
-0x86   4.62 V
-0x87   5.81 V
-0x88   7.01 V
-9x89   8.22 V
-0x8a   9.42 V
-0x8b  10.6  V
-0x8c  11.9  V
-0x8d  12.4  V
-0x8e  12.4  V
-0x8f  12.4  V

+
+Detection of these chips can sometimes be foiled because they can be in
+an internal state that allows no clean access. If you know the address
+of the chip, use a 'force' parameter; this will put them into a more
+well-behaved state first.
+
+The W8378* implements temperature sensors (three on the W83781D and W83782D,
+two on the W83783S), three fan rotation speed sensors, voltage sensors
+(seven on the W83781D, nine on the W83782D and six on the W83783S), VID
+lines, alarms with beep warnings, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. There is always one main
+temperature sensor, and one (W83783S) or two (W83781D and W83782D) other
+sensors. An alarm is triggered for the main sensor once when the
+Overtemperature Shutdown limit is crossed; it is triggered again as soon as
+it drops below the Hysteresis value. A more useful behavior
+can be found by setting the Hysteresis value to +127 degrees Celsius; in
+this case, alarms are issued during all the time when the actual temperature
+is above the Overtemperature Shutdown value. The driver sets the
+hysteresis value for temp1 to 127 at initialization.
+
+For the other temperature sensor(s), an alarm is triggered when the
+temperature gets higher then the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value. But on the
+W83781D, there is only one alarm that functions for both other sensors!
+Temperatures are guaranteed within a range of -55 to +125 degrees. The
+main temperature sensors has a resolution of 1 degree; the other sensor(s)
+of 0.5 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8 for the
+W83781D; 1, 2, 4, 8, 16, 32, 64 or 128 for the others) to give
+the readings more range or accuracy. Not all RPM values can accurately
+be represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.
+
+The VID lines encode the core voltage value: the voltage level your processor
+should work with. This is hardcoded by the mainboard and/or processor itself.
+It is a value in volts. When it is unconnected, you will often find the
+value 3.50 V here.
+
+The W83782D and W83783S temperature conversion machine understands about
+several kinds of temperature probes. You can program the so-called
+beta value in the sensor files. '1' is the PII/Celeron diode, '2' is the
+TN3904 transistor, and 3435 the default thermistor value. Other values
+are (not yet) supported.
+
+In addition to the alarms described above, there is a CHAS alarm on the
+chips which triggers if your computer case is open.
+
+When an alarm goes off, you can be warned by a beeping signal through
+your computer speaker. It is possible to enable all beeping globally,
+or only the beeping for some alarms.
+
+Individual alarm and beep bits:
+
+======== ==========================
+0x000001 in0
+0x000002 in1
+0x000004 in2
+0x000008 in3
+0x000010 temp1
+0x000020 temp2 (+temp3 on W83781D)
+0x000040 fan1
+0x000080 fan2
+0x000100 in4
+0x000200 in5
+0x000400 in6
+0x000800 fan3
+0x001000 chassis
+0x002000 temp3 (W83782D only)
+0x010000 in7 (W83782D only)
+0x020000 in8 (W83782D only)
+======== ==========================
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The chips only update values each 1.5 seconds; reading them more often
+will do no harm, but will return 'old' values.
+
+AS99127F PROBLEMS
+-----------------
+The as99127f support was developed without the benefit of a datasheet.
+In most cases it is treated as a w83781d (although revision 2 of the
+AS99127F looks more like a w83782d).
+This support will be BETA until a datasheet is released.
+One user has reported problems with fans stopping
+occasionally.
+
+Note that the individual beep bits are inverted from the other chips.
+The driver now takes care of this so that user-space applications
+don't have to know about it.
+
+Known problems:
+	- Problems with diode/thermistor settings (supported?)
+	- One user reports fans stopping under high server load.
+	- Revision 2 seems to have 2 PWM registers but we don't know
+	  how to handle them. More details below.
+
+These will not be fixed unless we get a datasheet.
+If you have problems, please lobby Asus to release a datasheet.
+Unfortunately several others have without success.
+Please do not send mail to us asking for better as99127f support.
+We have done the best we can without a datasheet.
+Please do not send mail to the author or the sensors group asking for
+a datasheet or ideas on how to convince Asus. We can't help.
+
+
+NOTES
+-----
+  783s has no in1 so that in[2-6] are compatible with the 781d/782d.
+
+  783s pin is programmable for -5V or temp1; defaults to -5V,
+  no control in driver so temp1 doesn't work.
+
+  782d and 783s datasheets differ on which is pwm1 and which is pwm2.
+  We chose to follow 782d.
+
+  782d and 783s pin is programmable for fan3 input or pwm2 output;
+  defaults to fan3 input.
+  If pwm2 is enabled (with echo 255 1 > pwm2), then
+  fan3 will report 0.
+
+  782d has pwm1-2 for ISA, pwm1-4 for i2c. (pwm3-4 share pins with
+  the ISA pins)

+Asus Clones
+-----------
+
+We have no datasheets for the Asus clones (AS99127F and ASB100 Bach).
+Here are some very useful information that were given to us by Alex Van
+Kaam about how to detect these chips, and how to read their values. He
+also gives advice for another Asus chipset, the Mozart-2 (which we
+don't support yet). Thanks Alex!
+
+I reworded some parts and added personal comments.
+
+Detection
+^^^^^^^^^
+
+AS99127F rev.1, AS99127F rev.2 and ASB100:
+- I2C address range: 0x29 - 0x2F
+- If register 0x58 holds 0x31 then we have an Asus (either ASB100 or AS99127F)
+- Which one depends on register 0x4F (manufacturer ID):
+
+  - 0x06 or 0x94: ASB100
+  - 0x12 or 0xC3: AS99127F rev.1
+  - 0x5C or 0xA3: AS99127F rev.2
+
+  Note that 0x5CA3 is Winbond's ID (WEC), which let us think Asus get their
+  AS99127F rev.2 direct from Winbond. The other codes mean ATT and DVC,
+  respectively. ATT could stand for Asustek something (although it would be
+  very badly chosen IMHO), I don't know what DVC could stand for. Maybe
+  these codes simply aren't meant to be decoded that way.
+
+Mozart-2:
+- I2C address: 0x77
+- If register 0x58 holds 0x56 or 0x10 then we have a Mozart-2
+- Of the Mozart there are 3 types:
+
+  - 0x58=0x56, 0x4E=0x94, 0x4F=0x36: Asus ASM58 Mozart-2
+  - 0x58=0x56, 0x4E=0x94, 0x4F=0x06: Asus AS2K129R Mozart-2
+  - 0x58=0x10, 0x4E=0x5C, 0x4F=0xA3: Asus ??? Mozart-2
+
+  You can handle all 3 the exact same way :)
+
+Temperature sensors
+^^^^^^^^^^^^^^^^^^^
+
+ASB100:
+  - sensor 1: register 0x27
+  - sensor 2 & 3 are the 2 LM75's on the SMBus
+  - sensor 4: register 0x17
+
+Remark:
+
+  I noticed that on Intel boards sensor 2 is used for the CPU
+  and 4 is ignored/stuck, on AMD boards sensor 4 is the CPU and sensor 2 is
+  either ignored or a socket temperature.
+
+AS99127F (rev.1 and 2 alike):
+  - sensor 1: register 0x27
+  - sensor 2 & 3 are the 2 LM75's on the SMBus
+
+Remark:
+
+  Register 0x5b is suspected to be temperature type selector. Bit 1
+  would control temp1, bit 3 temp2 and bit 5 temp3.
+
+Mozart-2:
+  - sensor 1: register 0x27
+  - sensor 2: register 0x13
+
+Fan sensors
+^^^^^^^^^^^
+
+ASB100, AS99127F (rev.1 and 2 alike):
+  - 3 fans, identical to the W83781D
+
+Mozart-2:
+  - 2 fans only, 1350000/RPM/div
+  - fan 1: register 0x28,  divisor on register 0xA1 (bits 4-5)
+  - fan 2: register 0x29,  divisor on register 0xA1 (bits 6-7)
+
+Voltages
+^^^^^^^^
+
+This is where there is a difference between AS99127F rev.1 and 2.
+
+Remark:
+
+  The difference is similar to the difference between
+  W83781D and W83782D.
+
+ASB100:
+  - in0=r(0x20)*0.016
+  - in1=r(0x21)*0.016
+  - in2=r(0x22)*0.016
+  - in3=r(0x23)*0.016*1.68
+  - in4=r(0x24)*0.016*3.8
+  - in5=r(0x25)*(-0.016)*3.97
+  - in6=r(0x26)*(-0.016)*1.666
+
+AS99127F rev.1:
+  - in0=r(0x20)*0.016
+  - in1=r(0x21)*0.016
+  - in2=r(0x22)*0.016
+  - in3=r(0x23)*0.016*1.68

+  - in5=r(0x25)*(-0.016)*3.97
+  - in6=r(0x26)*(-0.016)*1.503
+
+AS99127F rev.2:
+  - in0=r(0x20)*0.016
+  - in1=r(0x21)*0.016
+  - in2=r(0x22)*0.016
+  - in3=r(0x23)*0.016*1.68
+  - in4=r(0x24)*0.016*3.8
+  - in5=(r(0x25)*0.016-3.6)*5.14+3.6
+  - in6=(r(0x26)*0.016-3.6)*3.14+3.6
+
+Mozart-2:
+  - in0=r(0x20)*0.016
+  - in1=255
+  - in2=r(0x22)*0.016
+  - in3=r(0x23)*0.016*1.68
+  - in4=r(0x24)*0.016*4
+  - in5=255
+  - in6=255
+
+
+PWM
+^^^
+
+* Additional info about PWM on the AS99127F (may apply to other Asus
+  chips as well) by Jean Delvare as of 2004-04-09:
+
+AS99127F revision 2 seems to have two PWM registers at 0x59 and 0x5A,
+and a temperature sensor type selector at 0x5B (which basically means
+that they swapped registers 0x59 and 0x5B when you compare with Winbond
+chips).
+Revision 1 of the chip also has the temperature sensor type selector at
+0x5B, but PWM registers have no effect.
+
+We don't know exactly how the temperature sensor type selection works.
+Looks like bits 1-0 are for temp1, bits 3-2 for temp2 and bits 5-4 for
+temp3, although it is possible that only the most significant bit matters
+each time. So far, values other than 0 always broke the readings.
+
+PWM registers seem to be split in two parts: bit 7 is a mode selector,
+while the other bits seem to define a value or threshold.
+
+When bit 7 is clear, bits 6-0 seem to hold a threshold value. If the value
+is below a given limit, the fan runs at low speed. If the value is above
+the limit, the fan runs at full speed. We have no clue as to what the limit
+represents. Note that there seem to be some inertia in this mode, speed
+changes may need some time to trigger. Also, an hysteresis mechanism is
+suspected since walking through all the values increasingly and then
+decreasingly led to slightly different limits.
+
+When bit 7 is set, bits 3-0 seem to hold a threshold value, while bits 6-4
+would not be significant. If the value is below a given limit, the fan runs
+at full speed, while if it is above the limit it runs at low speed (so this
+is the contrary of the other mode, in a way). Here again, we don't know
+what the limit is supposed to represent.
+
+One remarkable thing is that the fans would only have two or three
+different speeds (transitional states left apart), not a whole range as
+you usually get with PWM.
+
+As a conclusion, you can write 0x00 or 0x8F to the PWM registers to make
+fans run at low speed, and 0x7F or 0x80 to make them run at full speed.
+
+Please contact us if you can figure out how it is supposed to work. As
+long as we don't know more, the w83781d driver doesn't handle PWM on
+AS99127F chips at all.
+
+* Additional info about PWM on the AS99127F rev.1 by Hector Martin:
+
+I've been fiddling around with the (in)famous 0x59 register and
+found out the following values do work as a form of coarse pwm:
+
+0x80
+ - seems to turn fans off after some time(1-2 minutes)... might be
+   some form of auto-fan-control based on temp? hmm (Qfan? this mobo is an
+   old ASUS, it isn't marketed as Qfan. Maybe some beta pre-attempt at Qfan
+   that was dropped at the BIOS)
+0x81
+ - off
+0x82
+ - slightly "on-ner" than off, but my fans do not get to move. I can
+   hear the high-pitched PWM sound that motors give off at too-low-pwm.
+0x83
+ - now they do move. Estimate about 70% speed or so.
+0x84-0x8f
+ - full on
+
+Changing the high nibble doesn't seem to do much except the high bit
+(0x80) must be set for PWM to work, else the current pwm doesn't seem to
+change.
+
+My mobo is an ASUS A7V266-E. This behavior is similar to what I got
+with speedfan under Windows, where 0-15% would be off, 15-2x% (can't
+remember the exact value) would be 70% and higher would be full on.
+
+* Additional info about PWM on the AS99127F rev.1 from lm-sensors
+  ticket #2350:
+
+I conducted some experiment on Asus P3B-F motherboard with AS99127F
+(Ver. 1).
+
+I confirm that 0x59 register control the CPU_Fan Header on this
+motherboard, and 0x5a register control PWR_Fan.
+
+In order to reduce the dependency of specific fan, the measurement is
+conducted with a digital scope without fan connected. I found out that
+P3B-F actually output variable DC voltage on fan header center pin,
+looks like PWM is filtered on this motherboard.
+
+Here are some of measurements:

-Module Parameters
------------------
-
-* init boolean
-  (default 0)
-  Use 'init=1' to have the driver do extra software initializations.
-  The default behavior is to do the minimum initialization possible
-  and depend on the BIOS to properly setup the chip. If you know you
-  have a w83791d and you're having problems, try init=1 before trying
-  reset=1.
-
-* reset boolean
-  (default 0)
-  Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default
-  behavior is no chip reset to preserve BIOS settings.
-
-* force_subclients=bus,caddr,saddr,saddr
-  This is used to force the i2c addresses for subclients of
-  a certain chip. Example usage is `force_subclients=0,0x2f,0x4a,0x4b'
-  to force the subclients of chip 0x2f on bus 0 to i2c addresses
-  0x4a and 0x4b.

-
-Description
------------
-
-This driver implements support for the Winbond W83791D chip. The W83791G
-chip appears to be the same as the W83791D but is lead free.
-
-Detection of the chip can sometimes be foiled because it can be in an
-internal state that allows no clean access (Bank with ID register is not
-currently selected). If you know the address of the chip, use a 'force'
-parameter; this will put it into a more well-behaved state first.
-
-The driver implements three temperature sensors, ten voltage sensors,
-five fan rotation speed sensors and manual PWM control of each fan.
-
-Temperatures are measured in degrees Celsius and measurement resolution is 1
-degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
-the temperature gets higher than the Overtemperature Shutdown value; it stays
-on until the temperature falls below the Hysteresis value.
-
-Voltage sensors (also known as IN sensors) report their values in millivolts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4, 8, 16,
-32, 64 or 128 for all fans) to give the readings more range or accuracy.
-
-Each fan controlled is controlled by PWM. The PWM duty cycle can be read and
-set for each fan separately. Valid values range from 0 (stop) to 255 (full).
-PWM 1-3 support Thermal Cruise mode, in which the PWMs are automatically
-regulated to keep respectively temp 1-3 at a certain target temperature.
-See below for the description of the sysfs-interface.
-
-The w83791d has a global bit used to enable beeping from the speaker when an
-alarm is triggered as well as a bitmask to enable or disable the beep for
-specific alarms. You need both the global beep enable bit and the
-corresponding beep bit to be on for a triggered alarm to sound a beep.
-
-The sysfs interface to the global enable is via the sysfs beep_enable file.
-This file is used for both legacy and new code.
-
-The sysfs interface to the beep bitmask has migrated from the original legacy
-method of a single sysfs beep_mask file to a newer method using multiple
-*_beep files as described in .../Documentation/hwmon/sysfs-interface.
-
-A similar change has occurred for the bitmap corresponding to the alarms. The

+Module Parameters
+-----------------
+
+* init boolean
+    (default 0)
+
+    Use 'init=1' to have the driver do extra software initializations.
+    The default behavior is to do the minimum initialization possible
+    and depend on the BIOS to properly setup the chip. If you know you
+    have a w83791d and you're having problems, try init=1 before trying
+    reset=1.
+
+* reset boolean
+    (default 0)
+
+    Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default
+    behavior is no chip reset to preserve BIOS settings.
+
+* force_subclients=bus,caddr,saddr,saddr
+    This is used to force the i2c addresses for subclients of
+    a certain chip. Example usage is `force_subclients=0,0x2f,0x4a,0x4b`
+    to force the subclients of chip 0x2f on bus 0 to i2c addresses
+    0x4a and 0x4b.
+
+
+Description
+-----------
+
+This driver implements support for the Winbond W83791D chip. The W83791G
+chip appears to be the same as the W83791D but is lead free.
+
+Detection of the chip can sometimes be foiled because it can be in an
+internal state that allows no clean access (Bank with ID register is not
+currently selected). If you know the address of the chip, use a 'force'
+parameter; this will put it into a more well-behaved state first.
+
+The driver implements three temperature sensors, ten voltage sensors,
+five fan rotation speed sensors and manual PWM control of each fan.
+
+Temperatures are measured in degrees Celsius and measurement resolution is 1
+degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
+the temperature gets higher than the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4, 8, 16,
+32, 64 or 128 for all fans) to give the readings more range or accuracy.
+
+Each fan controlled is controlled by PWM. The PWM duty cycle can be read and
+set for each fan separately. Valid values range from 0 (stop) to 255 (full).
+PWM 1-3 support Thermal Cruise mode, in which the PWMs are automatically
+regulated to keep respectively temp 1-3 at a certain target temperature.
+See below for the description of the sysfs-interface.
+
+The w83791d has a global bit used to enable beeping from the speaker when an
+alarm is triggered as well as a bitmask to enable or disable the beep for
+specific alarms. You need both the global beep enable bit and the
+corresponding beep bit to be on for a triggered alarm to sound a beep.
+
+The sysfs interface to the global enable is via the sysfs beep_enable file.
+This file is used for both legacy and new code.
+
+The sysfs interface to the beep bitmask has migrated from the original legacy
+method of a single sysfs beep_mask file to a newer method using multiple
+`*_beep` files as described in `Documentation/hwmon/sysfs-interface.rst`.
+
+A similar change has occurred for the bitmap corresponding to the alarms. The
+original legacy method used a single sysfs alarms file containing a bitmap
+of triggered alarms. The newer method uses multiple sysfs `*_alarm` files
+(again following the pattern described in sysfs-interface).
+
+Since both methods read and write the underlying hardware, they can be used
+interchangeably and changes in one will automatically be reflected by
+the other. If you use the legacy bitmask method, your user-space code is
+responsible for handling the fact that the alarms and beep_mask bitmaps
+are not the same (see the table below).
+
+NOTE: All new code should be written to use the newer sysfs-interface
+specification as that avoids bitmap problems and is the preferred interface
+going forward.
+
+The driver reads the hardware chip values at most once every three seconds.
+User mode code requesting values more often will receive cached values.

-Description
------------
-
-This driver implements support for the Winbond W83792AD/D.

-internal state that allows no clean access (Bank with ID register is not
-currently selected). If you know the address of the chip, use a 'force'
-parameter; this will put it into a more well-behaved state first.
-
-The driver implements three temperature sensors, seven fan rotation speed
-sensors, nine voltage sensors, and two automatic fan regulation
-strategies called: Smart Fan I (Thermal Cruise mode) and Smart Fan II.
-
-The driver also implements up to seven fan control outputs: pwm1-7.  Pwm1-7
-can be configured to PWM output or Analogue DC output via their associated
-pwmX_mode. Outputs pwm4 through pwm7 may or may not be present depending on
-how the W83792AD/D was configured by the BIOS.
-
-Automatic fan control mode is possible only for fan1-fan3.
-
-For all pwmX outputs, a value of 0 means minimum fan speed and a value of
-255 means maximum fan speed.
-
-Temperatures are measured in degrees Celsius and measurement resolution is 1
-degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
-the temperature gets higher than the Overtemperature Shutdown value; it stays
-on until the temperature falls below the Hysteresis value.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is

-
-Voltage sensors (also known as IN sensors) report their values in millivolts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit.
-
-Alarms are provided as output from "realtime status register". Following bits

-
-In addition to the alarms described above, there is a CHAS alarm on the chips
-which triggers if your computer case is open (This one is latched, contrary

-W83792D PROBLEMS
-----------------
-Known problems:
-	- This driver is only for Winbond W83792D C version device, there
-	  are also some motherboards with B version W83792D device. The
-	  calculation method to in6-in7(measured value, limits) is a little
-	  different between C and B version. C or B version can be identified
-	  by CR[0x49h].
-	- The function of vid and vrm has not been finished, because I'm NOT
-	  very familiar with them. Adding support is welcome.
- 	- The function of chassis open detection needs more tests.
-	- If you have ASUS server board and chip was not found: Then you will
-	  need to upgrade to latest (or beta) BIOS. If it does not help please
-	  contact us.
-
-Fan control
------------
-
-Manual mode
------------
-
-Works as expected. You just need to specify desired PWM/DC value (fan speed)
-in appropriate pwm# file.
-
-Thermal cruise
---------------
-
-In this mode, W83792D provides the Smart Fan system to automatically control
-fan speed to keep the temperatures of CPU and the system within specific
-range. At first a wanted temperature and interval must be set. This is done
-via thermal_cruise# file. The tolerance# file serves to create T +- tolerance
-interval. The fan speed will be lowered as long as the current temperature
-remains below the thermal_cruise# +- tolerance# value. Once the temperature
-exceeds the high limit (T+tolerance), the fan will be turned on with a
-specific speed set by pwm# and automatically controlled its PWM duty cycle
-with the temperature varying. Three conditions may occur:
-
-(1) If the temperature still exceeds the high limit, PWM duty
-cycle will increase slowly.
-
-(2) If the temperature goes below the high limit, but still above the low
-limit (T-tolerance), the fan speed will be fixed at the current speed because
-the temperature is in the target range.
-
-(3) If the temperature goes below the low limit, PWM duty cycle will decrease
-slowly to 0 or a preset stop value until the temperature exceeds the low
-limit. (The preset stop value handling is not yet implemented in driver)
-
-Smart Fan II
-------------
-
-W83792D also provides a special mode for fan. Four temperature points are
-available. When related temperature sensors detects the temperature in preset
-temperature region (sf2_point@_fan# +- tolerance#) it will cause fans to run
-on programmed value from sf2_level@_fan#. You need to set four temperatures
-for each fan.
-
-
-/sys files
-----------
-
-pwm[1-7] - this file stores PWM duty cycle or DC value (fan speed) in range:
-	0 (stop) to 255 (full)
-pwm[1-3]_enable - this file controls mode of fan/temperature control:
-            * 0 Disabled
-            * 1 Manual mode
-            * 2 Smart Fan II

-            * 1 PWM
-thermal_cruise[1-3] - Selects the desired temperature for cruise (degC)
-tolerance[1-3] - Value in degrees of Celsius (degC) for +- T
-sf2_point[1-4]_fan[1-3] - four temperature points for each fan for Smart Fan II
-sf2_level[1-3]_fan[1-3] - three PWM/DC levels for each fan for Smart Fan II

+	- This driver is only for Winbond W83792D C version device, there
+	  are also some motherboards with B version W83792D device. The
+	  calculation method to in6-in7(measured value, limits) is a little
+	  different between C and B version. C or B version can be identified
+	  by CR[0x49h].
+	- The function of vid and vrm has not been finished, because I'm NOT
+	  very familiar with them. Adding support is welcome.
+	- The function of chassis open detection needs more tests.
+	- If you have ASUS server board and chip was not found: Then you will
+	  need to upgrade to latest (or beta) BIOS. If it does not help please
+	  contact us.
+
+Fan control
+-----------
+
+Manual mode
+-----------
+
+Works as expected. You just need to specify desired PWM/DC value (fan speed)
+in appropriate pwm# file.
+
+Thermal cruise
+--------------
+
+In this mode, W83792D provides the Smart Fan system to automatically control
+fan speed to keep the temperatures of CPU and the system within specific
+range. At first a wanted temperature and interval must be set. This is done
+via thermal_cruise# file. The tolerance# file serves to create T +- tolerance
+interval. The fan speed will be lowered as long as the current temperature
+remains below the thermal_cruise# +- tolerance# value. Once the temperature
+exceeds the high limit (T+tolerance), the fan will be turned on with a
+specific speed set by pwm# and automatically controlled its PWM duty cycle
+with the temperature varying. Three conditions may occur:
+
+(1) If the temperature still exceeds the high limit, PWM duty
+cycle will increase slowly.
+
+(2) If the temperature goes below the high limit, but still above the low
+limit (T-tolerance), the fan speed will be fixed at the current speed because
+the temperature is in the target range.
+
+(3) If the temperature goes below the low limit, PWM duty cycle will decrease
+slowly to 0 or a preset stop value until the temperature exceeds the low
+limit. (The preset stop value handling is not yet implemented in driver)
+
+Smart Fan II
+------------
+
+W83792D also provides a special mode for fan. Four temperature points are
+available. When related temperature sensors detects the temperature in preset
+temperature region (sf2_point@_fan# +- tolerance#) it will cause fans to run
+on programmed value from sf2_level@_fan#. You need to set four temperatures
+for each fan.
+
+
+/sys files
+----------
+
+pwm[1-7]
+	- this file stores PWM duty cycle or DC value (fan speed) in range:
+
+	    0 (stop) to 255 (full)
+pwm[1-3]_enable
+	- this file controls mode of fan/temperature control:
+
+	    * 0 Disabled
+	    * 1 Manual mode
+	    * 2 Smart Fan II
+	    * 3 Thermal Cruise
+pwm[1-7]_mode
+	- Select PWM or DC mode
+
+	    * 0 DC
+	    * 1 PWM
+thermal_cruise[1-3]
+	- Selects the desired temperature for cruise (degC)
+tolerance[1-3]
+	- Value in degrees of Celsius (degC) for +- T
+sf2_point[1-4]_fan[1-3]
+	- four temperature points for each fan for Smart Fan II
+sf2_level[1-3]_fan[1-3]
+	- three PWM/DC levels for each fan for Smart Fan II

-Module parameters
------------------
-
-* reset int
-  (default 0)
-  This parameter is not recommended, it will lose motherboard specific
-  settings. Use 'reset=1' to reset the chip when loading this module.
-
-* force_subclients=bus,caddr,saddr1,saddr2
-  This is used to force the i2c addresses for subclients of
-  a certain chip. Typical usage is `force_subclients=0,0x2f,0x4a,0x4b'
-  to force the subclients of chip 0x2f on bus 0 to i2c addresses
-  0x4a and 0x4b.
-
-
-Description
------------
-
-This driver implements support for Winbond W83793G/W83793R chips.
-
-* Exported features
-  This driver exports 10 voltage sensors, up to 12 fan tachometer inputs,
-  6 remote temperatures, up to 8 sets of PWM fan controls, SmartFan
-  (automatic fan speed control) on all temperature/PWM combinations, 2
-  sets of 6-pin CPU VID input.
-
-* Sensor resolutions
-  If your motherboard maker used the reference design, the resolution of
-  voltage0-2 is 2mV, resolution of voltage3/4/5 is 16mV, 8mV for voltage6,
-  24mV for voltage7/8. Temp1-4 have a 0.25 degree Celsius resolution,
-  temp5-6 have a 1 degree Celsiis resolution.
-
-* Temperature sensor types
-  Temp1-4 have 2 possible types. It can be read from (and written to)
-  temp[1-4]_type.
-  - If the value is 3, it starts monitoring using a remote termal diode
-    (default).
-  - If the value is 6, it starts monitoring using the temperature sensor
-    in Intel CPU and get result by PECI.
-  Temp5-6 can be connected to external thermistors (value of
-  temp[5-6]_type is 4).
-
-* Alarm mechanism
-  For voltage sensors, an alarm triggers if the measured value is below
-  the low voltage limit or over the high voltage limit.
-  For temperature sensors, an alarm triggers if the measured value goes
-  above the high temperature limit, and wears off only after the measured
-  value drops below the hysteresis value.
-  For fan sensors, an alarm triggers if the measured value is below the
-  low speed limit.
-
-* SmartFan/PWM control
-  If you want to set a pwm fan to manual mode, you just need to make sure it
-  is not controlled by any temp channel, for example, you want to set fan1
-  to manual mode, you need to check the value of temp[1-6]_fan_map, make
-  sure bit 0 is cleared in the 6 values. And then set the pwm1 value to
-  control the fan.
-
-  Each temperature channel can control all the 8 PWM outputs (by setting the
-  corresponding bit in tempX_fan_map), you can set the temperature channel
-  mode using temp[1-6]_pwm_enable, 2 is Thermal Cruise mode and 3
-  is the SmartFanII mode. Temperature channels will try to speed up or
-  slow down all controlled fans, this means one fan can receive different
-  PWM value requests from different temperature channels, but the chip
-  will always pick the safest (max) PWM value for each fan.
-
-  In Thermal Cruise mode, the chip attempts to keep the temperature at a
-  predefined value, within a tolerance margin. So if tempX_input >
-  thermal_cruiseX + toleranceX, the chip will increase the PWM value,
-  if tempX_input < thermal_cruiseX - toleranceX, the chip will decrease
-  the PWM value. If the temperature is within the tolerance range, the PWM
-  value is left unchanged.
-
-  SmartFanII works differently, you have to define up to 7 PWM, temperature
-  trip points, defining a PWM/temperature curve which the chip will follow.
-  While not fundamentally different from the Thermal Cruise mode, the
-  implementation is quite different, giving you a finer-grained control.
-
-* Chassis
-  If the case open alarm triggers, it will stay in this state unless cleared
-  by writing 0 to the sysfs file "intrusion0_alarm".
-
-* VID and VRM
-  The VRM version is detected automatically, don't modify the it unless you
-  *do* know the cpu VRM version and it's not properly detected.
-
-
-Notes
------
-
-  Only Fan1-5 and PWM1-3 are guaranteed to always exist, other fan inputs and
-  PWM outputs may or may not exist depending on the chip pin configuration.

-Description
------------
-
-The W83L785TS-S is a digital temperature sensor. It senses the
-temperature of a single external diode. The high limit is
-theoretically defined as 85 or 100 degrees C through a combination
-of external resistors, so the user cannot change it. Values seen so
-far suggest that the two possible limits are actually 95 and 110
-degrees C. The datasheet is rather poor and obviously inaccurate
-on several points including this one.
-
-All temperature values are given in degrees Celsius. Resolution
-is 1.0 degree. See the datasheet for details.
-
-The w83l785ts driver will not update its values more frequently than
-every other second; reading them more often will do no harm, but will
-return 'old' values.
-
-Known Issues
-------------
-
-On some systems (Asus), the BIOS is known to interfere with the driver
-and cause read errors. Or maybe the W83L785TS-S chip is simply unreliable,
-we don't really know. The driver will retry a given number of times
-(5 by default) and then give up, returning the old value (or 0 if
-there is no old value). It seems to work well enough so that you should
-not notice anything. Thanks to James Bolt for helping test this feature.

-Description
------------
-
-This driver supports hardware monitoring for Intersil / Zilker Labs ZL6100 and
-compatible digital DC-DC controllers.
-
-The driver is a client driver to the core PMBus driver. Please see
-Documentation/hwmon/pmbus and Documentation.hwmon/pmbus-core for details
-on PMBus client drivers.
-
-
-Usage Notes
------------
-
-This driver does not auto-detect devices. You will have to instantiate the
-devices explicitly. Please see Documentation/i2c/instantiating-devices for
-details.
-
-WARNING: Do not access chip registers using the i2cdump command, and do not use
-any of the i2ctools commands on a command register used to save and restore
-configuration data (0x11, 0x12, 0x15, 0x16, and 0xf4). The chips supported by
-this driver interpret any access to those command registers (including read
-commands) as request to execute the command in question. Unless write accesses
-to those registers are protected, this may result in power loss, board resets,
-and/or Flash corruption. Worst case, your board may turn into a brick.
-
-
-Platform data support
----------------------
-
-The driver supports standard PMBus driver platform data.
-
-
-Module parameters
------------------
-
-delay
------
-
-Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C
-bus accesses. According to Intersil, the minimum interval is 2 ms, though 1 ms
-appears to be sufficient and has not caused any problems in testing. The problem
-is known to affect all currently supported chips. For manual override, the
-driver provides a writeable module parameter, 'delay', which can be used to set
-the interval to a value between 0 and 65,535 microseconds.
-
-
-Sysfs entries
--------------
-
-The following attributes are supported. Limits are read-write; all other
-attributes are read-only.
-

+(Un)patching Callbacks
+======================
+
+Livepatch (un)patch-callbacks provide a mechanism for livepatch modules
+to execute callback functions when a kernel object is (un)patched.  They
+can be considered a **power feature** that **extends livepatching abilities**
+to include:
+
+  - Safe updates to global data
+
+  - "Patches" to init and probe functions
+
+  - Patching otherwise unpatchable code (i.e. assembly)
+
+In most cases, (un)patch callbacks will need to be used in conjunction
+with memory barriers and kernel synchronization primitives, like
+mutexes/spinlocks, or even stop_machine(), to avoid concurrency issues.
+
+1. Motivation
+=============
+
+Callbacks differ from existing kernel facilities:
+
+  - Module init/exit code doesn't run when disabling and re-enabling a
+    patch.
+
+  - A module notifier can't stop a to-be-patched module from loading.
+
+Callbacks are part of the klp_object structure and their implementation
+is specific to that klp_object.  Other livepatch objects may or may not
+be patched, irrespective of the target klp_object's current state.
+
+2. Callback types
+=================
+
+Callbacks can be registered for the following livepatch actions:
+
+  * Pre-patch
+                 - before a klp_object is patched
+
+  * Post-patch
+                 - after a klp_object has been patched and is active
+                   across all tasks
+
+  * Pre-unpatch
+                 - before a klp_object is unpatched (ie, patched code is
+                   active), used to clean up post-patch callback
+                   resources
+
+  * Post-unpatch
+                 - after a klp_object has been patched, all code has
+                   been restored and no tasks are running patched code,
+                   used to cleanup pre-patch callback resources
+
+3. How it works
+===============
+
+Each callback is optional, omitting one does not preclude specifying any
+other.  However, the livepatching core executes the handlers in
+symmetry: pre-patch callbacks have a post-unpatch counterpart and
+post-patch callbacks have a pre-unpatch counterpart.  An unpatch
+callback will only be executed if its corresponding patch callback was
+executed.  Typical use cases pair a patch handler that acquires and
+configures resources with an unpatch handler tears down and releases
+those same resources.
+
+A callback is only executed if its host klp_object is loaded.  For
+in-kernel vmlinux targets, this means that callbacks will always execute
+when a livepatch is enabled/disabled.  For patch target kernel modules,
+callbacks will only execute if the target module is loaded.  When a
+module target is (un)loaded, its callbacks will execute only if the
+livepatch module is enabled.
+
+The pre-patch callback, if specified, is expected to return a status
+code (0 for success, -ERRNO on error).  An error status code indicates
+to the livepatching core that patching of the current klp_object is not
+safe and to stop the current patching request.  (When no pre-patch
+callback is provided, the transition is assumed to be safe.)  If a
+pre-patch callback returns failure, the kernel's module loader will:
+
+  - Refuse to load a livepatch, if the livepatch is loaded after
+    targeted code.
+
+    or:
+
+  - Refuse to load a module, if the livepatch was already successfully
+    loaded.
+
+No post-patch, pre-unpatch, or post-unpatch callbacks will be executed
+for a given klp_object if the object failed to patch, due to a failed
+pre_patch callback or for any other reason.
+
+If a patch transition is reversed, no pre-unpatch handlers will be run
+(this follows the previously mentioned symmetry -- pre-unpatch callbacks
+will only occur if their corresponding post-patch callback executed).
+
+If the object did successfully patch, but the patch transition never
+started for some reason (e.g., if another object failed to patch),
+only the post-unpatch callback will be called.
+
+4. Use cases
+============
+
+Sample livepatch modules demonstrating the callback API can be found in
+samples/livepatch/ directory.  These samples were modified for use in
+kselftests and can be found in the lib/livepatch directory.
+
+Global data update
+------------------
+
+A pre-patch callback can be useful to update a global variable.  For
+example, 75ff39ccc1bd ("tcp: make challenge acks less predictable")
+changes a global sysctl, as well as patches the tcp_send_challenge_ack()
+function.
+
+In this case, if we're being super paranoid, it might make sense to
+patch the data *after* patching is complete with a post-patch callback,
+so that tcp_send_challenge_ack() could first be changed to read
+sysctl_tcp_challenge_ack_limit with READ_ONCE.
+
+__init and probe function patches support
+-----------------------------------------
+
+Although __init and probe functions are not directly livepatch-able, it
+may be possible to implement similar updates via pre/post-patch
+callbacks.
+
+The commit ``48900cb6af42 ("virtio-net: drop NETIF_F_FRAGLIST")`` change the way that
+virtnet_probe() initialized its driver's net_device features.  A
+pre/post-patch callback could iterate over all such devices, making a
+similar change to their hw_features value.  (Client functions of the
+value may need to be updated accordingly.)

+===================================
+Atomic Replace & Cumulative Patches
+===================================
+
+There might be dependencies between livepatches. If multiple patches need
+to do different changes to the same function(s) then we need to define
+an order in which the patches will be installed. And function implementations
+from any newer livepatch must be done on top of the older ones.
+
+This might become a maintenance nightmare. Especially when more patches
+modified the same function in different ways.
+
+An elegant solution comes with the feature called "Atomic Replace". It allows
+creation of so called "Cumulative Patches". They include all wanted changes
+from all older livepatches and completely replace them in one transition.
+
+Usage
+-----
+
+The atomic replace can be enabled by setting "replace" flag in struct klp_patch,
+for example::
+
+	static struct klp_patch patch = {
+		.mod = THIS_MODULE,
+		.objs = objs,
+		.replace = true,
+	};
+
+All processes are then migrated to use the code only from the new patch.
+Once the transition is finished, all older patches are automatically
+disabled.
+
+Ftrace handlers are transparently removed from functions that are no
+longer modified by the new cumulative patch.
+
+As a result, the livepatch authors might maintain sources only for one
+cumulative patch. It helps to keep the patch consistent while adding or
+removing various fixes or features.
+
+Users could keep only the last patch installed on the system after
+the transition to has finished. It helps to clearly see what code is
+actually in use. Also the livepatch might then be seen as a "normal"
+module that modifies the kernel behavior. The only difference is that
+it can be updated at runtime without breaking its functionality.
+
+
+Features
+--------
+
+The atomic replace allows:
+
+  - Atomically revert some functions in a previous patch while
+    upgrading other functions.
+
+  - Remove eventual performance impact caused by core redirection
+    for functions that are no longer patched.
+
+  - Decrease user confusion about dependencies between livepatches.
+
+
+Limitations:
+------------
+
+  - Once the operation finishes, there is no straightforward way
+    to reverse it and restore the replaced patches atomically.
+
+    A good practice is to set .replace flag in any released livepatch.
+    Then re-adding an older livepatch is equivalent to downgrading
+    to that patch. This is safe as long as the livepatches do _not_ do
+    extra modifications in (un)patching callbacks or in the module_init()
+    or module_exit() functions, see below.
+
+    Also note that the replaced patch can be removed and loaded again
+    only when the transition was not forced.
+
+
+  - Only the (un)patching callbacks from the _new_ cumulative livepatch are
+    executed. Any callbacks from the replaced patches are ignored.
+
+    In other words, the cumulative patch is responsible for doing any actions
+    that are necessary to properly replace any older patch.
+
+    As a result, it might be dangerous to replace newer cumulative patches by
+    older ones. The old livepatches might not provide the necessary callbacks.
+
+    This might be seen as a limitation in some scenarios. But it makes life
+    easier in many others. Only the new cumulative livepatch knows what
+    fixes/features are added/removed and what special actions are necessary
+    for a smooth transition.
+
+    In any case, it would be a nightmare to think about the order of
+    the various callbacks and their interactions if the callbacks from all
+    enabled patches were called.
+
+
+  - There is no special handling of shadow variables. Livepatch authors
+    must create their own rules how to pass them from one cumulative
+    patch to the other. Especially that they should not blindly remove
+    them in module_exit() functions.
+
+    A good practice might be to remove shadow variables in the post-unpatch
+    callback. It is called only when the livepatch is properly disabled.

+    7. Limitations
+
+
+1. Motivation
+=============
+
+There are many situations where users are reluctant to reboot a system. It may
+be because their system is performing complex scientific computations or under
+heavy load during peak usage. In addition to keeping systems up and running,
+users want to also have a stable and secure system. Livepatching gives users
+both by allowing for function calls to be redirected; thus, fixing critical
+functions without a system reboot.
+
+
+2. Kprobes, Ftrace, Livepatching
+================================
+
+There are multiple mechanisms in the Linux kernel that are directly related
+to redirection of code execution; namely: kernel probes, function tracing,
+and livepatching:
+
+  - The kernel probes are the most generic. The code can be redirected by
+    putting a breakpoint instruction instead of any instruction.
+
+  - The function tracer calls the code from a predefined location that is
+    close to the function entry point. This location is generated by the
+    compiler using the '-pg' gcc option.
+
+  - Livepatching typically needs to redirect the code at the very beginning
+    of the function entry before the function parameters or the stack
+    are in any way modified.
+
+All three approaches need to modify the existing code at runtime. Therefore
+they need to be aware of each other and not step over each other's toes.
+Most of these problems are solved by using the dynamic ftrace framework as
+a base. A Kprobe is registered as a ftrace handler when the function entry
+is probed, see CONFIG_KPROBES_ON_FTRACE. Also an alternative function from
+a live patch is called with the help of a custom ftrace handler. But there are
+some limitations, see below.
+
+
+3. Consistency model
+====================
+
+Functions are there for a reason. They take some input parameters, get or
+release locks, read, process, and even write some data in a defined way,
+have return values. In other words, each function has a defined semantic.
+
+Many fixes do not change the semantic of the modified functions. For
+example, they add a NULL pointer or a boundary check, fix a race by adding
+a missing memory barrier, or add some locking around a critical section.
+Most of these changes are self contained and the function presents itself
+the same way to the rest of the system. In this case, the functions might
+be updated independently one by one.
+
+But there are more complex fixes. For example, a patch might change
+ordering of locking in multiple functions at the same time. Or a patch
+might exchange meaning of some temporary structures and update
+all the relevant functions. In this case, the affected unit
+(thread, whole kernel) need to start using all new versions of
+the functions at the same time. Also the switch must happen only
+when it is safe to do so, e.g. when the affected locks are released
+or no data are stored in the modified structures at the moment.
+
+The theory about how to apply functions a safe way is rather complex.
+The aim is to define a so-called consistency model. It attempts to define
+conditions when the new implementation could be used so that the system
+stays consistent.
+
+Livepatch has a consistency model which is a hybrid of kGraft and
+kpatch:  it uses kGraft's per-task consistency and syscall barrier
+switching combined with kpatch's stack trace switching.  There are also
+a number of fallback options which make it quite flexible.
+
+Patches are applied on a per-task basis, when the task is deemed safe to
+switch over.  When a patch is enabled, livepatch enters into a
+transition state where tasks are converging to the patched state.
+Usually this transition state can complete in a few seconds.  The same
+sequence occurs when a patch is disabled, except the tasks converge from
+the patched state to the unpatched state.
+
+An interrupt handler inherits the patched state of the task it
+interrupts.  The same is true for forked tasks: the child inherits the
+patched state of the parent.
+
+Livepatch uses several complementary approaches to determine when it's
+safe to patch tasks:
+
+1. The first and most effective approach is stack checking of sleeping
+   tasks.  If no affected functions are on the stack of a given task,
+   the task is patched.  In most cases this will patch most or all of
+   the tasks on the first try.  Otherwise it'll keep trying
+   periodically.  This option is only available if the architecture has
+   reliable stacks (HAVE_RELIABLE_STACKTRACE).
+
+2. The second approach, if needed, is kernel exit switching.  A
+   task is switched when it returns to user space from a system call, a
+   user space IRQ, or a signal.  It's useful in the following cases:
+
+   a) Patching I/O-bound user tasks which are sleeping on an affected
+      function.  In this case you have to send SIGSTOP and SIGCONT to
+      force it to exit the kernel and be patched.
+   b) Patching CPU-bound user tasks.  If the task is highly CPU-bound
+      then it will get patched the next time it gets interrupted by an
+      IRQ.
+
+3. For idle "swapper" tasks, since they don't ever exit the kernel, they
+   instead have a klp_update_patch_state() call in the idle loop which
+   allows them to be patched before the CPU enters the idle state.
+
+   (Note there's not yet such an approach for kthreads.)
+
+Architectures which don't have HAVE_RELIABLE_STACKTRACE solely rely on
+the second approach. It's highly likely that some tasks may still be
+running with an old version of the function, until that function
+returns. In this case you would have to signal the tasks. This
+especially applies to kthreads. They may not be woken up and would need
+to be forced. See below for more information.
+
+Unless we can come up with another way to patch kthreads, architectures
+without HAVE_RELIABLE_STACKTRACE are not considered fully supported by
+the kernel livepatching.
+
+The /sys/kernel/livepatch/<patch>/transition file shows whether a patch
+is in transition.  Only a single patch can be in transition at a given
+time.  A patch can remain in transition indefinitely, if any of the tasks
+are stuck in the initial patch state.
+
+A transition can be reversed and effectively canceled by writing the
+opposite value to the /sys/kernel/livepatch/<patch>/enabled file while
+the transition is in progress.  Then all the tasks will attempt to
+converge back to the original patch state.
+
+There's also a /proc/<pid>/patch_state file which can be used to
+determine which tasks are blocking completion of a patching operation.
+If a patch is in transition, this file shows 0 to indicate the task is
+unpatched and 1 to indicate it's patched.  Otherwise, if no patch is in
+transition, it shows -1.  Any tasks which are blocking the transition
+can be signaled with SIGSTOP and SIGCONT to force them to change their
+patched state. This may be harmful to the system though. Sending a fake signal
+to all remaining blocking tasks is a better alternative. No proper signal is
+actually delivered (there is no data in signal pending structures). Tasks are
+interrupted or woken up, and forced to change their patched state. The fake
+signal is automatically sent every 15 seconds.
+
+Administrator can also affect a transition through
+/sys/kernel/livepatch/<patch>/force attribute. Writing 1 there clears
+TIF_PATCH_PENDING flag of all tasks and thus forces the tasks to the patched
+state. Important note! The force attribute is intended for cases when the
+transition gets stuck for a long time because of a blocking task. Administrator
+is expected to collect all necessary data (namely stack traces of such blocking
+tasks) and request a clearance from a patch distributor to force the transition.
+Unauthorized usage may cause harm to the system. It depends on the nature of the
+patch, which functions are (un)patched, and which functions the blocking tasks
+are sleeping in (/proc/<pid>/stack may help here). Removal (rmmod) of patch
+modules is permanently disabled when the force feature is used. It cannot be
+guaranteed there is no task sleeping in such module. It implies unbounded
+reference count if a patch module is disabled and enabled in a loop.
+
+Moreover, the usage of force may also affect future applications of live
+patches and cause even more harm to the system. Administrator should first
+consider to simply cancel a transition (see above). If force is used, reboot
+should be planned and no more live patches applied.
+
+3.1 Adding consistency model support to new architectures
+---------------------------------------------------------
+
+For adding consistency model support to new architectures, there are a
+few options:
+
+1) Add CONFIG_HAVE_RELIABLE_STACKTRACE.  This means porting objtool, and
+   for non-DWARF unwinders, also making sure there's a way for the stack
+   tracing code to detect interrupts on the stack.
+
+2) Alternatively, ensure that every kthread has a call to
+   klp_update_patch_state() in a safe location.  Kthreads are typically
+   in an infinite loop which does some action repeatedly.  The safe
+   location to switch the kthread's patch state would be at a designated
+   point in the loop where there are no locks taken and all data
+   structures are in a well-defined state.
+
+   The location is clear when using workqueues or the kthread worker
+   API.  These kthreads process independent actions in a generic loop.
+
+   It's much more complicated with kthreads which have a custom loop.
+   There the safe location must be carefully selected on a case-by-case
+   basis.
+
+   In that case, arches without HAVE_RELIABLE_STACKTRACE would still be
+   able to use the non-stack-checking parts of the consistency model:
+
+   a) patching user tasks when they cross the kernel/user space
+      boundary; and
+
+   b) patching kthreads and idle tasks at their designated patch points.
+
+   This option isn't as good as option 1 because it requires signaling
+   user tasks and waking kthreads to patch them.  But it could still be
+   a good backup option for those architectures which don't have
+   reliable stack traces yet.
+
+
+4. Livepatch module
+===================
+
+Livepatches are distributed using kernel modules, see
+samples/livepatch/livepatch-sample.c.
+
+The module includes a new implementation of functions that we want
+to replace. In addition, it defines some structures describing the
+relation between the original and the new implementation. Then there
+is code that makes the kernel start using the new code when the livepatch
+module is loaded. Also there is code that cleans up before the
+livepatch module is removed. All this is explained in more details in
+the next sections.
+
+
+4.1. New functions
+------------------
+
+New versions of functions are typically just copied from the original
+sources. A good practice is to add a prefix to the names so that they
+can be distinguished from the original ones, e.g. in a backtrace. Also
+they can be declared as static because they are not called directly
+and do not need the global visibility.
+
+The patch contains only functions that are really modified. But they
+might want to access functions or data from the original source file
+that may only be locally accessible. This can be solved by a special
+relocation section in the generated livepatch module, see
+Documentation/livepatch/module-elf-format.rst for more details.
+
+
+4.2. Metadata
+-------------
+
+The patch is described by several structures that split the information
+into three levels:
+
+  - struct klp_func is defined for each patched function. It describes
+    the relation between the original and the new implementation of a
+    particular function.
+
+    The structure includes the name, as a string, of the original function.
+    The function address is found via kallsyms at runtime.
+
+    Then it includes the address of the new function. It is defined
+    directly by assigning the function pointer. Note that the new
+    function is typically defined in the same source file.
+
+    As an optional parameter, the symbol position in the kallsyms database can
+    be used to disambiguate functions of the same name. This is not the
+    absolute position in the database, but rather the order it has been found
+    only for a particular object ( vmlinux or a kernel module ). Note that
+    kallsyms allows for searching symbols according to the object name.
+
+  - struct klp_object defines an array of patched functions (struct
+    klp_func) in the same object. Where the object is either vmlinux
+    (NULL) or a module name.
+
+    The structure helps to group and handle functions for each object
+    together. Note that patched modules might be loaded later than
+    the patch itself and the relevant functions might be patched
+    only when they are available.
+
+
+  - struct klp_patch defines an array of patched objects (struct
+    klp_object).
+
+    This structure handles all patched functions consistently and eventually,
+    synchronously. The whole patch is applied only when all patched
+    symbols are found. The only exception are symbols from objects
+    (kernel modules) that have not been loaded yet.
+
+    For more details on how the patch is applied on a per-task basis,
+    see the "Consistency model" section.
+
+
+5. Livepatch life-cycle
+=======================
+
+Livepatching can be described by five basic operations:
+loading, enabling, replacing, disabling, removing.
+
+Where the replacing and the disabling operations are mutually
+exclusive. They have the same result for the given patch but
+not for the system.
+
+
+5.1. Loading
+------------
+
+The only reasonable way is to enable the patch when the livepatch kernel
+module is being loaded. For this, klp_enable_patch() has to be called
+in the module_init() callback. There are two main reasons:
+
+First, only the module has an easy access to the related struct klp_patch.
+
+Second, the error code might be used to refuse loading the module when
+the patch cannot get enabled.
+
+
+5.2. Enabling
+-------------
+
+The livepatch gets enabled by calling klp_enable_patch() from
+the module_init() callback. The system will start using the new
+implementation of the patched functions at this stage.
+
+First, the addresses of the patched functions are found according to their
+names. The special relocations, mentioned in the section "New functions",
+are applied. The relevant entries are created under
+/sys/kernel/livepatch/<name>. The patch is rejected when any above
+operation fails.
+
+Second, livepatch enters into a transition state where tasks are converging
+to the patched state. If an original function is patched for the first
+time, a function specific struct klp_ops is created and an universal
+ftrace handler is registered\ [#]_. This stage is indicated by a value of '1'
+in /sys/kernel/livepatch/<name>/transition. For more information about
+this process, see the "Consistency model" section.
+
+Finally, once all tasks have been patched, the 'transition' value changes
+to '0'.
+
+.. [#]
+
+    Note that functions might be patched multiple times. The ftrace handler
+    is registered only once for a given function. Further patches just add
+    an entry to the list (see field `func_stack`) of the struct klp_ops.
+    The right implementation is selected by the ftrace handler, see
+    the "Consistency model" section.
+
+    That said, it is highly recommended to use cumulative livepatches
+    because they help keeping the consistency of all changes. In this case,
+    functions might be patched two times only during the transition period.
+
+
+5.3. Replacing
+--------------
+
+All enabled patches might get replaced by a cumulative patch that
+has the .replace flag set.
+
+Once the new patch is enabled and the 'transition' finishes then
+all the functions (struct klp_func) associated with the replaced
+patches are removed from the corresponding struct klp_ops. Also
+the ftrace handler is unregistered and the struct klp_ops is
+freed when the related function is not modified by the new patch
+and func_stack list becomes empty.
+
+See Documentation/livepatch/cumulative-patches.rst for more details.
+
+
+5.4. Disabling
+--------------
+
+Enabled patches might get disabled by writing '0' to
+/sys/kernel/livepatch/<name>/enabled.
+
+First, livepatch enters into a transition state where tasks are converging
+to the unpatched state. The system starts using either the code from
+the previously enabled patch or even the original one. This stage is
+indicated by a value of '1' in /sys/kernel/livepatch/<name>/transition.
+For more information about this process, see the "Consistency model"
+section.
+
+Second, once all tasks have been unpatched, the 'transition' value changes
+to '0'. All the functions (struct klp_func) associated with the to-be-disabled
+patch are removed from the corresponding struct klp_ops. The ftrace handler
+is unregistered and the struct klp_ops is freed when the func_stack list
+becomes empty.
+
+Third, the sysfs interface is destroyed.
+
+
+5.5. Removing
+-------------
+
+Module removal is only safe when there are no users of functions provided
+by the module. This is the reason why the force feature permanently
+disables the removal. Only when the system is successfully transitioned
+to a new patch state (patched/unpatched) without being forced it is
+guaranteed that no task sleeps or runs in the old code.
+
+
+6. Sysfs
+========
+
+Information about the registered patches can be found under
+/sys/kernel/livepatch. The patches could be enabled and disabled
+by writing there.
+
+/sys/kernel/livepatch/<patch>/force attributes allow administrator to affect a
+patching operation.
+
+See Documentation/ABI/testing/sysfs-kernel-livepatch for more details.
+
+
+7. Limitations
+==============
+
+The current Livepatch implementation has several limitations:
+
+  - Only functions that can be traced could be patched.
+
+    Livepatch is based on the dynamic ftrace. In particular, functions
+    implementing ftrace or the livepatch ftrace handler could not be
+    patched. Otherwise, the code would end up in an infinite loop. A
+    potential mistake is prevented by marking the problematic functions
+    by "notrace".
+
+
+
+  - Livepatch works reliably only when the dynamic ftrace is located at
+    the very beginning of the function.
+
+    The function need to be redirected before the stack or the function
+    parameters are modified in any way. For example, livepatch requires
+    using -fentry gcc compiler option on x86_64.
+
+    One exception is the PPC port. It uses relative addressing and TOC.
+    Each function has to handle TOC and save LR before it could call
+    the ftrace handler. This operation has to be reverted on return.
+    Fortunately, the generic ftrace code has the same problem and all
+    this is handled on the ftrace level.
+
+
+  - Kretprobes using the ftrace framework conflict with the patched
+    functions.
+
+    Both kretprobes and livepatches use a ftrace handler that modifies
+    the return address. The first user wins. Either the probe or the patch
+    is rejected when the handler is already in use by the other.
+
+
+  - Kprobes in the original function are ignored when the code is
+    redirected to the new implementation.
+
+    There is a work in progress to add warnings about this situation.

-
-1. Motivation
-=============
-
-There are many situations where users are reluctant to reboot a system. It may
-be because their system is performing complex scientific computations or under
-heavy load during peak usage. In addition to keeping systems up and running,
-users want to also have a stable and secure system. Livepatching gives users
-both by allowing for function calls to be redirected; thus, fixing critical
-functions without a system reboot.
-
-
-2. Kprobes, Ftrace, Livepatching
-================================
-
-There are multiple mechanisms in the Linux kernel that are directly related
-to redirection of code execution; namely: kernel probes, function tracing,
-and livepatching:
-
-  + The kernel probes are the most generic. The code can be redirected by
-    putting a breakpoint instruction instead of any instruction.
-
-  + The function tracer calls the code from a predefined location that is
-    close to the function entry point. This location is generated by the
-    compiler using the '-pg' gcc option.
-
-  + Livepatching typically needs to redirect the code at the very beginning
-    of the function entry before the function parameters or the stack
-    are in any way modified.
-
-All three approaches need to modify the existing code at runtime. Therefore
-they need to be aware of each other and not step over each other's toes.
-Most of these problems are solved by using the dynamic ftrace framework as
-a base. A Kprobe is registered as a ftrace handler when the function entry
-is probed, see CONFIG_KPROBES_ON_FTRACE. Also an alternative function from
-a live patch is called with the help of a custom ftrace handler. But there are
-some limitations, see below.
-
-
-3. Consistency model
-====================
-
-Functions are there for a reason. They take some input parameters, get or
-release locks, read, process, and even write some data in a defined way,
-have return values. In other words, each function has a defined semantic.
-
-Many fixes do not change the semantic of the modified functions. For
-example, they add a NULL pointer or a boundary check, fix a race by adding
-a missing memory barrier, or add some locking around a critical section.
-Most of these changes are self contained and the function presents itself
-the same way to the rest of the system. In this case, the functions might
-be updated independently one by one.
-
-But there are more complex fixes. For example, a patch might change
-ordering of locking in multiple functions at the same time. Or a patch
-might exchange meaning of some temporary structures and update
-all the relevant functions. In this case, the affected unit
-(thread, whole kernel) need to start using all new versions of
-the functions at the same time. Also the switch must happen only
-when it is safe to do so, e.g. when the affected locks are released
-or no data are stored in the modified structures at the moment.
-
-The theory about how to apply functions a safe way is rather complex.
-The aim is to define a so-called consistency model. It attempts to define
-conditions when the new implementation could be used so that the system
-stays consistent.
-
-Livepatch has a consistency model which is a hybrid of kGraft and
-kpatch:  it uses kGraft's per-task consistency and syscall barrier
-switching combined with kpatch's stack trace switching.  There are also
-a number of fallback options which make it quite flexible.
-
-Patches are applied on a per-task basis, when the task is deemed safe to
-switch over.  When a patch is enabled, livepatch enters into a
-transition state where tasks are converging to the patched state.
-Usually this transition state can complete in a few seconds.  The same
-sequence occurs when a patch is disabled, except the tasks converge from
-the patched state to the unpatched state.
-
-An interrupt handler inherits the patched state of the task it
-interrupts.  The same is true for forked tasks: the child inherits the
-patched state of the parent.
-
-Livepatch uses several complementary approaches to determine when it's
-safe to patch tasks:
-
-1. The first and most effective approach is stack checking of sleeping
-   tasks.  If no affected functions are on the stack of a given task,
-   the task is patched.  In most cases this will patch most or all of
-   the tasks on the first try.  Otherwise it'll keep trying
-   periodically.  This option is only available if the architecture has
-   reliable stacks (HAVE_RELIABLE_STACKTRACE).
-
-2. The second approach, if needed, is kernel exit switching.  A
-   task is switched when it returns to user space from a system call, a
-   user space IRQ, or a signal.  It's useful in the following cases:
-
-   a) Patching I/O-bound user tasks which are sleeping on an affected
-      function.  In this case you have to send SIGSTOP and SIGCONT to
-      force it to exit the kernel and be patched.
-   b) Patching CPU-bound user tasks.  If the task is highly CPU-bound
-      then it will get patched the next time it gets interrupted by an
-      IRQ.
-
-3. For idle "swapper" tasks, since they don't ever exit the kernel, they
-   instead have a klp_update_patch_state() call in the idle loop which
-   allows them to be patched before the CPU enters the idle state.
-
-   (Note there's not yet such an approach for kthreads.)
-
-Architectures which don't have HAVE_RELIABLE_STACKTRACE solely rely on
-the second approach. It's highly likely that some tasks may still be
-running with an old version of the function, until that function
-returns. In this case you would have to signal the tasks. This
-especially applies to kthreads. They may not be woken up and would need
-to be forced. See below for more information.
-
-Unless we can come up with another way to patch kthreads, architectures
-without HAVE_RELIABLE_STACKTRACE are not considered fully supported by
-the kernel livepatching.
-
-The /sys/kernel/livepatch/<patch>/transition file shows whether a patch
-is in transition.  Only a single patch can be in transition at a given
-time.  A patch can remain in transition indefinitely, if any of the tasks
-are stuck in the initial patch state.
-
-A transition can be reversed and effectively canceled by writing the
-opposite value to the /sys/kernel/livepatch/<patch>/enabled file while
-the transition is in progress.  Then all the tasks will attempt to
-converge back to the original patch state.
-
-There's also a /proc/<pid>/patch_state file which can be used to
-determine which tasks are blocking completion of a patching operation.
-If a patch is in transition, this file shows 0 to indicate the task is
-unpatched and 1 to indicate it's patched.  Otherwise, if no patch is in
-transition, it shows -1.  Any tasks which are blocking the transition
-can be signaled with SIGSTOP and SIGCONT to force them to change their
-patched state. This may be harmful to the system though. Sending a fake signal
-to all remaining blocking tasks is a better alternative. No proper signal is
-actually delivered (there is no data in signal pending structures). Tasks are
-interrupted or woken up, and forced to change their patched state. The fake
-signal is automatically sent every 15 seconds.
-
-Administrator can also affect a transition through
-/sys/kernel/livepatch/<patch>/force attribute. Writing 1 there clears
-TIF_PATCH_PENDING flag of all tasks and thus forces the tasks to the patched
-state. Important note! The force attribute is intended for cases when the
-transition gets stuck for a long time because of a blocking task. Administrator
-is expected to collect all necessary data (namely stack traces of such blocking
-tasks) and request a clearance from a patch distributor to force the transition.
-Unauthorized usage may cause harm to the system. It depends on the nature of the
-patch, which functions are (un)patched, and which functions the blocking tasks
-are sleeping in (/proc/<pid>/stack may help here). Removal (rmmod) of patch
-modules is permanently disabled when the force feature is used. It cannot be
-guaranteed there is no task sleeping in such module. It implies unbounded
-reference count if a patch module is disabled and enabled in a loop.
-
-Moreover, the usage of force may also affect future applications of live
-patches and cause even more harm to the system. Administrator should first
-consider to simply cancel a transition (see above). If force is used, reboot
-should be planned and no more live patches applied.
-
-3.1 Adding consistency model support to new architectures
----------------------------------------------------------
-
-For adding consistency model support to new architectures, there are a
-few options:
-
-1) Add CONFIG_HAVE_RELIABLE_STACKTRACE.  This means porting objtool, and
-   for non-DWARF unwinders, also making sure there's a way for the stack
-   tracing code to detect interrupts on the stack.
-
-2) Alternatively, ensure that every kthread has a call to
-   klp_update_patch_state() in a safe location.  Kthreads are typically
-   in an infinite loop which does some action repeatedly.  The safe
-   location to switch the kthread's patch state would be at a designated
-   point in the loop where there are no locks taken and all data
-   structures are in a well-defined state.
-
-   The location is clear when using workqueues or the kthread worker
-   API.  These kthreads process independent actions in a generic loop.
-
-   It's much more complicated with kthreads which have a custom loop.
-   There the safe location must be carefully selected on a case-by-case
-   basis.
-
-   In that case, arches without HAVE_RELIABLE_STACKTRACE would still be
-   able to use the non-stack-checking parts of the consistency model:
-
-   a) patching user tasks when they cross the kernel/user space
-      boundary; and
-
-   b) patching kthreads and idle tasks at their designated patch points.
-
-   This option isn't as good as option 1 because it requires signaling
-   user tasks and waking kthreads to patch them.  But it could still be
-   a good backup option for those architectures which don't have
-   reliable stack traces yet.
-
-
-4. Livepatch module
-===================
-
-Livepatches are distributed using kernel modules, see
-samples/livepatch/livepatch-sample.c.
-
-The module includes a new implementation of functions that we want
-to replace. In addition, it defines some structures describing the
-relation between the original and the new implementation. Then there
-is code that makes the kernel start using the new code when the livepatch
-module is loaded. Also there is code that cleans up before the
-livepatch module is removed. All this is explained in more details in
-the next sections.
-
-
-4.1. New functions
-------------------
-
-New versions of functions are typically just copied from the original
-sources. A good practice is to add a prefix to the names so that they
-can be distinguished from the original ones, e.g. in a backtrace. Also
-they can be declared as static because they are not called directly
-and do not need the global visibility.
-
-The patch contains only functions that are really modified. But they
-might want to access functions or data from the original source file
-that may only be locally accessible. This can be solved by a special
-relocation section in the generated livepatch module, see
-Documentation/livepatch/module-elf-format.txt for more details.
-
-
-4.2. Metadata
--------------
-
-The patch is described by several structures that split the information
-into three levels:
-
-  + struct klp_func is defined for each patched function. It describes
-    the relation between the original and the new implementation of a
-    particular function.
-
-    The structure includes the name, as a string, of the original function.
-    The function address is found via kallsyms at runtime.
-
-    Then it includes the address of the new function. It is defined
-    directly by assigning the function pointer. Note that the new
-    function is typically defined in the same source file.
-
-    As an optional parameter, the symbol position in the kallsyms database can
-    be used to disambiguate functions of the same name. This is not the
-    absolute position in the database, but rather the order it has been found
-    only for a particular object ( vmlinux or a kernel module ). Note that
-    kallsyms allows for searching symbols according to the object name.
-
-  + struct klp_object defines an array of patched functions (struct
-    klp_func) in the same object. Where the object is either vmlinux
-    (NULL) or a module name.
-
-    The structure helps to group and handle functions for each object
-    together. Note that patched modules might be loaded later than
-    the patch itself and the relevant functions might be patched
-    only when they are available.
-
-
-  + struct klp_patch defines an array of patched objects (struct
-    klp_object).
-
-    This structure handles all patched functions consistently and eventually,
-    synchronously. The whole patch is applied only when all patched
-    symbols are found. The only exception are symbols from objects
-    (kernel modules) that have not been loaded yet.

-
-5. Livepatch life-cycle
-=======================
-
-Livepatching can be described by five basic operations:
-loading, enabling, replacing, disabling, removing.
-
-Where the replacing and the disabling operations are mutually
-exclusive. They have the same result for the given patch but
-not for the system.
-
-
-5.1. Loading
-------------
-
-The only reasonable way is to enable the patch when the livepatch kernel
-module is being loaded. For this, klp_enable_patch() has to be called
-in the module_init() callback. There are two main reasons:
-
-First, only the module has an easy access to the related struct klp_patch.
-
-Second, the error code might be used to refuse loading the module when
-the patch cannot get enabled.
-
-
-5.2. Enabling
--------------
-
-The livepatch gets enabled by calling klp_enable_patch() from
-the module_init() callback. The system will start using the new
-implementation of the patched functions at this stage.
-
-First, the addresses of the patched functions are found according to their
-names. The special relocations, mentioned in the section "New functions",
-are applied. The relevant entries are created under
-/sys/kernel/livepatch/<name>. The patch is rejected when any above
-operation fails.
-
-Second, livepatch enters into a transition state where tasks are converging
-to the patched state. If an original function is patched for the first
-time, a function specific struct klp_ops is created and an universal
-ftrace handler is registered[*]. This stage is indicated by a value of '1'
-in /sys/kernel/livepatch/<name>/transition. For more information about
-this process, see the "Consistency model" section.
-
-Finally, once all tasks have been patched, the 'transition' value changes
-to '0'.
-
-[*] Note that functions might be patched multiple times. The ftrace handler
-    is registered only once for a given function. Further patches just add
-    an entry to the list (see field `func_stack`) of the struct klp_ops.
-    The right implementation is selected by the ftrace handler, see
-    the "Consistency model" section.
-
-    That said, it is highly recommended to use cumulative livepatches
-    because they help keeping the consistency of all changes. In this case,
-    functions might be patched two times only during the transition period.
-
-
-5.3. Replacing
---------------
-
-All enabled patches might get replaced by a cumulative patch that
-has the .replace flag set.
-
-Once the new patch is enabled and the 'transition' finishes then
-all the functions (struct klp_func) associated with the replaced
-patches are removed from the corresponding struct klp_ops. Also
-the ftrace handler is unregistered and the struct klp_ops is
-freed when the related function is not modified by the new patch
-and func_stack list becomes empty.
-
-See Documentation/livepatch/cumulative-patches.txt for more details.
-
-
-5.4. Disabling
---------------
-
-Enabled patches might get disabled by writing '0' to
-/sys/kernel/livepatch/<name>/enabled.
-
-First, livepatch enters into a transition state where tasks are converging
-to the unpatched state. The system starts using either the code from
-the previously enabled patch or even the original one. This stage is
-indicated by a value of '1' in /sys/kernel/livepatch/<name>/transition.
-For more information about this process, see the "Consistency model"
-section.
-
-Second, once all tasks have been unpatched, the 'transition' value changes
-to '0'. All the functions (struct klp_func) associated with the to-be-disabled
-patch are removed from the corresponding struct klp_ops. The ftrace handler
-is unregistered and the struct klp_ops is freed when the func_stack list
-becomes empty.
-
-Third, the sysfs interface is destroyed.
-
-
-5.5. Removing
--------------
-
-Module removal is only safe when there are no users of functions provided
-by the module. This is the reason why the force feature permanently
-disables the removal. Only when the system is successfully transitioned
-to a new patch state (patched/unpatched) without being forced it is
-guaranteed that no task sleeps or runs in the old code.
-
-
-6. Sysfs
-========
-
-Information about the registered patches can be found under
-/sys/kernel/livepatch. The patches could be enabled and disabled
-by writing there.
-
-/sys/kernel/livepatch/<patch>/force attributes allow administrator to affect a
-patching operation.
-
-See Documentation/ABI/testing/sysfs-kernel-livepatch for more details.
-
-
-7. Limitations
-==============
-
-The current Livepatch implementation has several limitations:
-
-  + Only functions that can be traced could be patched.
-
-    Livepatch is based on the dynamic ftrace. In particular, functions
-    implementing ftrace or the livepatch ftrace handler could not be
-    patched. Otherwise, the code would end up in an infinite loop. A
-    potential mistake is prevented by marking the problematic functions
-    by "notrace".
-
-
-
-  + Livepatch works reliably only when the dynamic ftrace is located at
-    the very beginning of the function.
-
-    The function need to be redirected before the stack or the function
-    parameters are modified in any way. For example, livepatch requires
-    using -fentry gcc compiler option on x86_64.
-
-    One exception is the PPC port. It uses relative addressing and TOC.
-    Each function has to handle TOC and save LR before it could call
-    the ftrace handler. This operation has to be reverted on return.
-    Fortunately, the generic ftrace code has the same problem and all
-    this is handled on the ftrace level.
-
-
-  + Kretprobes using the ftrace framework conflict with the patched
-    functions.
-
-    Both kretprobes and livepatches use a ftrace handler that modifies
-    the return address. The first user wins. Either the probe or the patch
-    is rejected when the handler is already in use by the other.
-
-
-  + Kprobes in the original function are ignored when the code is
-    redirected to the new implementation.
-
-    There is a work in progress to add warnings about this situation.

+===========================
+Livepatch module Elf format
+===========================
+
+This document outlines the Elf format requirements that livepatch modules must follow.
+
+
+.. Table of Contents
+
+   1. Background and motivation
+   2. Livepatch modinfo field
+   3. Livepatch relocation sections
+      3.1 Livepatch relocation section format
+   4. Livepatch symbols
+      4.1 A livepatch module's symbol table
+      4.2 Livepatch symbol format
+   5. Architecture-specific sections
+   6. Symbol table and Elf section access
+
+1. Background and motivation
+============================
+
+Formerly, livepatch required separate architecture-specific code to write
+relocations. However, arch-specific code to write relocations already
+exists in the module loader, so this former approach produced redundant
+code. So, instead of duplicating code and re-implementing what the module
+loader can already do, livepatch leverages existing code in the module
+loader to perform the all the arch-specific relocation work. Specifically,
+livepatch reuses the apply_relocate_add() function in the module loader to
+write relocations. The patch module Elf format described in this document
+enables livepatch to be able to do this. The hope is that this will make
+livepatch more easily portable to other architectures and reduce the amount
+of arch-specific code required to port livepatch to a particular
+architecture.
+
+Since apply_relocate_add() requires access to a module's section header
+table, symbol table, and relocation section indices, Elf information is
+preserved for livepatch modules (see section 5). Livepatch manages its own
+relocation sections and symbols, which are described in this document. The
+Elf constants used to mark livepatch symbols and relocation sections were
+selected from OS-specific ranges according to the definitions from glibc.
+
+Why does livepatch need to write its own relocations?
+-----------------------------------------------------
+A typical livepatch module contains patched versions of functions that can
+reference non-exported global symbols and non-included local symbols.
+Relocations referencing these types of symbols cannot be left in as-is
+since the kernel module loader cannot resolve them and will therefore
+reject the livepatch module. Furthermore, we cannot apply relocations that
+affect modules not yet loaded at patch module load time (e.g. a patch to a
+driver that is not loaded). Formerly, livepatch solved this problem by
+embedding special "dynrela" (dynamic rela) sections in the resulting patch
+module Elf output. Using these dynrela sections, livepatch could resolve
+symbols while taking into account its scope and what module the symbol
+belongs to, and then manually apply the dynamic relocations. However this
+approach required livepatch to supply arch-specific code in order to write
+these relocations. In the new format, livepatch manages its own SHT_RELA
+relocation sections in place of dynrela sections, and the symbols that the
+relas reference are special livepatch symbols (see section 2 and 3). The
+arch-specific livepatch relocation code is replaced by a call to
+apply_relocate_add().
+
+2. Livepatch modinfo field
+==========================
+
+Livepatch modules are required to have the "livepatch" modinfo attribute.
+See the sample livepatch module in samples/livepatch/ for how this is done.
+
+Livepatch modules can be identified by users by using the 'modinfo' command
+and looking for the presence of the "livepatch" field. This field is also
+used by the kernel module loader to identify livepatch modules.
+
+Example:
+--------
+
+**Modinfo output:**
+
+::
+
+	% modinfo livepatch-meminfo.ko
+	filename:		livepatch-meminfo.ko
+	livepatch:		Y
+	license:		GPL
+	depends:
+	vermagic:		4.3.0+ SMP mod_unload
+
+3. Livepatch relocation sections
+================================
+
+A livepatch module manages its own Elf relocation sections to apply
+relocations to modules as well as to the kernel (vmlinux) at the
+appropriate time. For example, if a patch module patches a driver that is
+not currently loaded, livepatch will apply the corresponding livepatch
+relocation section(s) to the driver once it loads.
+
+Each "object" (e.g. vmlinux, or a module) within a patch module may have
+multiple livepatch relocation sections associated with it (e.g. patches to
+multiple functions within the same object). There is a 1-1 correspondence
+between a livepatch relocation section and the target section (usually the
+text section of a function) to which the relocation(s) apply. It is
+also possible for a livepatch module to have no livepatch relocation
+sections, as in the case of the sample livepatch module (see
+samples/livepatch).
+
+Since Elf information is preserved for livepatch modules (see Section 5), a
+livepatch relocation section can be applied simply by passing in the
+appropriate section index to apply_relocate_add(), which then uses it to
+access the relocation section and apply the relocations.
+
+Every symbol referenced by a rela in a livepatch relocation section is a
+livepatch symbol. These must be resolved before livepatch can call
+apply_relocate_add(). See Section 3 for more information.
+
+3.1 Livepatch relocation section format
+=======================================
+
+Livepatch relocation sections must be marked with the SHF_RELA_LIVEPATCH
+section flag. See include/uapi/linux/elf.h for the definition. The module
+loader recognizes this flag and will avoid applying those relocation sections
+at patch module load time. These sections must also be marked with SHF_ALLOC,
+so that the module loader doesn't discard them on module load (i.e. they will
+be copied into memory along with the other SHF_ALLOC sections).
+
+The name of a livepatch relocation section must conform to the following
+format::
+
+  .klp.rela.objname.section_name
+  ^        ^^     ^ ^          ^
+  |________||_____| |__________|
+     [A]      [B]        [C]
+
+[A]
+  The relocation section name is prefixed with the string ".klp.rela."
+
+[B]
+  The name of the object (i.e. "vmlinux" or name of module) to
+  which the relocation section belongs follows immediately after the prefix.
+
+[C]
+  The actual name of the section to which this relocation section applies.
+
+Examples:
+---------
+
+**Livepatch relocation section names:**

+  .klp.rela.ext4.text.ext4_attr_store

+
+[*]
+  Every symbol referenced by a relocation is a livepatch symbol.
+
+4. Livepatch symbols
+====================
+
+Livepatch symbols are symbols referred to by livepatch relocation sections.
+These are symbols accessed from new versions of functions for patched
+objects, whose addresses cannot be resolved by the module loader (because
+they are local or unexported global syms). Since the module loader only
+resolves exported syms, and not every symbol referenced by the new patched
+functions is exported, livepatch symbols were introduced. They are used
+also in cases where we cannot immediately know the address of a symbol when
+a patch module loads. For example, this is the case when livepatch patches
+a module that is not loaded yet. In this case, the relevant livepatch
+symbols are resolved simply when the target module loads. In any case, for
+any livepatch relocation section, all livepatch symbols referenced by that
+section must be resolved before livepatch can call apply_relocate_add() for
+that reloc section.
+
+Livepatch symbols must be marked with SHN_LIVEPATCH so that the module
+loader can identify and ignore them. Livepatch modules keep these symbols
+in their symbol tables, and the symbol table is made accessible through
+module->symtab.
+
+4.1 A livepatch module's symbol table
+=====================================
+Normally, a stripped down copy of a module's symbol table (containing only
+"core" symbols) is made available through module->symtab (See layout_symtab()
+in kernel/module.c). For livepatch modules, the symbol table copied into memory
+on module load must be exactly the same as the symbol table produced when the
+patch module was compiled. This is because the relocations in each livepatch
+relocation section refer to their respective symbols with their symbol indices,
+and the original symbol indices (and thus the symtab ordering) must be
+preserved in order for apply_relocate_add() to find the right symbol.
+
+For example, take this particular rela from a livepatch module:::
+
+  Relocation section '.klp.rela.btrfs.text.btrfs_feature_attr_show' at offset 0x2ba0 contains 4 entries:
+      Offset             Info             Type               Symbol's Value  Symbol's Name + Addend
+  000000000000001f  0000005e00000002 R_X86_64_PC32          0000000000000000 .klp.sym.vmlinux.printk,0 - 4
+
+  This rela refers to the symbol '.klp.sym.vmlinux.printk,0', and the symbol index is encoded
+  in 'Info'. Here its symbol index is 0x5e, which is 94 in decimal, which refers to the
+  symbol index 94.
+  And in this patch module's corresponding symbol table, symbol index 94 refers to that very symbol:
+  [ snip ]
+  94: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.printk,0
+  [ snip ]
+
+4.2 Livepatch symbol format
+===========================
+
+Livepatch symbols must have their section index marked as SHN_LIVEPATCH, so
+that the module loader can identify them and not attempt to resolve them.
+See include/uapi/linux/elf.h for the actual definitions.
+
+Livepatch symbol names must conform to the following format::
+
+  .klp.sym.objname.symbol_name,sympos
+  ^       ^^     ^ ^         ^ ^
+  |_______||_____| |_________| |
+     [A]     [B]       [C]    [D]
+
+[A]
+  The symbol name is prefixed with the string ".klp.sym."
+
+[B]
+  The name of the object (i.e. "vmlinux" or name of module) to
+  which the symbol belongs follows immediately after the prefix.
+
+[C]
+  The actual name of the symbol.
+
+[D]
+  The position of the symbol in the object (as according to kallsyms)
+  This is used to differentiate duplicate symbols within the same
+  object. The symbol position is expressed numerically (0, 1, 2...).
+  The symbol position of a unique symbol is 0.
+
+Examples:
+---------
+
+**Livepatch symbol names:**
+
+::
+
+	.klp.sym.vmlinux.snprintf,0
+	.klp.sym.vmlinux.printk,0
+	.klp.sym.btrfs.btrfs_ktype,0
+
+**`readelf --symbols` output for a patch module:**
+
+::
+
+  Symbol table '.symtab' contains 127 entries:
+     Num:    Value          Size Type    Bind   Vis     Ndx         Name
+     [ snip ]
+      73: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.snprintf,0
+      74: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.capable,0
+      75: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.find_next_bit,0
+      76: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.si_swapinfo,0
+    [ snip ]                                               ^
+                                                           |
+                                                          [*]
+
+[*]
+  Note that the 'Ndx' (Section index) for these symbols is SHN_LIVEPATCH (0xff20).
+  "OS" means OS-specific.
+
+5. Architecture-specific sections
+=================================
+Architectures may override arch_klp_init_object_loaded() to perform
+additional arch-specific tasks when a target module loads, such as applying
+arch-specific sections. On x86 for example, we must apply per-object
+.altinstructions and .parainstructions sections when a target module loads.
+These sections must be prefixed with ".klp.arch.$objname." so that they can
+be easily identified when iterating through a patch module's Elf sections
+(See arch/x86/kernel/livepatch.c for a complete example).
+
+6. Symbol table and Elf section access
+======================================
+A livepatch module's symbol table is accessible through module->symtab.
+
+Since apply_relocate_add() requires access to a module's section headers,
+symbol table, and relocation section indices, Elf information is preserved for
+livepatch modules and is made accessible by the module loader through
+module->klp_info, which is a klp_modinfo struct. When a livepatch module loads,
+this struct is filled in by the module loader. Its fields are documented below::
+
+	struct klp_modinfo {
+		Elf_Ehdr hdr; /* Elf header */
+		Elf_Shdr *sechdrs; /* Section header table */
+		char *secstrings; /* String table for the section headers */
+		unsigned int symndx; /* The symbol table section index */

-----------------------------
-0. Background and motivation
-----------------------------
-
-Formerly, livepatch required separate architecture-specific code to write
-relocations. However, arch-specific code to write relocations already
-exists in the module loader, so this former approach produced redundant
-code. So, instead of duplicating code and re-implementing what the module
-loader can already do, livepatch leverages existing code in the module
-loader to perform the all the arch-specific relocation work. Specifically,
-livepatch reuses the apply_relocate_add() function in the module loader to
-write relocations. The patch module Elf format described in this document
-enables livepatch to be able to do this. The hope is that this will make
-livepatch more easily portable to other architectures and reduce the amount
-of arch-specific code required to port livepatch to a particular
-architecture.
-
-Since apply_relocate_add() requires access to a module's section header
-table, symbol table, and relocation section indices, Elf information is
-preserved for livepatch modules (see section 5). Livepatch manages its own
-relocation sections and symbols, which are described in this document. The
-Elf constants used to mark livepatch symbols and relocation sections were
-selected from OS-specific ranges according to the definitions from glibc.
-
-0.1 Why does livepatch need to write its own relocations?
----------------------------------------------------------
-A typical livepatch module contains patched versions of functions that can
-reference non-exported global symbols and non-included local symbols.
-Relocations referencing these types of symbols cannot be left in as-is
-since the kernel module loader cannot resolve them and will therefore
-reject the livepatch module. Furthermore, we cannot apply relocations that
-affect modules not yet loaded at patch module load time (e.g. a patch to a
-driver that is not loaded). Formerly, livepatch solved this problem by
-embedding special "dynrela" (dynamic rela) sections in the resulting patch
-module Elf output. Using these dynrela sections, livepatch could resolve
-symbols while taking into account its scope and what module the symbol
-belongs to, and then manually apply the dynamic relocations. However this
-approach required livepatch to supply arch-specific code in order to write
-these relocations. In the new format, livepatch manages its own SHT_RELA
-relocation sections in place of dynrela sections, and the symbols that the
-relas reference are special livepatch symbols (see section 2 and 3). The
-arch-specific livepatch relocation code is replaced by a call to
-apply_relocate_add().
-
-================================
-PATCH MODULE FORMAT REQUIREMENTS
-================================
-
---------------------------
-1. Livepatch modinfo field
---------------------------
-
-Livepatch modules are required to have the "livepatch" modinfo attribute.
-See the sample livepatch module in samples/livepatch/ for how this is done.
-
-Livepatch modules can be identified by users by using the 'modinfo' command
-and looking for the presence of the "livepatch" field. This field is also
-used by the kernel module loader to identify livepatch modules.
-
-Example modinfo output:
------------------------
-% modinfo livepatch-meminfo.ko
-filename:		livepatch-meminfo.ko
-livepatch:		Y
-license:		GPL
-depends:
-vermagic:		4.3.0+ SMP mod_unload
-
---------------------------------
-2. Livepatch relocation sections
---------------------------------
-
--------------------------------------------
-2.1 What are livepatch relocation sections?
--------------------------------------------
-A livepatch module manages its own Elf relocation sections to apply
-relocations to modules as well as to the kernel (vmlinux) at the
-appropriate time. For example, if a patch module patches a driver that is
-not currently loaded, livepatch will apply the corresponding livepatch
-relocation section(s) to the driver once it loads.
-
-Each "object" (e.g. vmlinux, or a module) within a patch module may have
-multiple livepatch relocation sections associated with it (e.g. patches to
-multiple functions within the same object). There is a 1-1 correspondence
-between a livepatch relocation section and the target section (usually the
-text section of a function) to which the relocation(s) apply. It is
-also possible for a livepatch module to have no livepatch relocation
-sections, as in the case of the sample livepatch module (see
-samples/livepatch).
-
-Since Elf information is preserved for livepatch modules (see Section 5), a
-livepatch relocation section can be applied simply by passing in the
-appropriate section index to apply_relocate_add(), which then uses it to
-access the relocation section and apply the relocations.
-
-Every symbol referenced by a rela in a livepatch relocation section is a
-livepatch symbol. These must be resolved before livepatch can call
-apply_relocate_add(). See Section 3 for more information.
-
----------------------------------------
-2.2 Livepatch relocation section format
----------------------------------------
-
-2.2.1 Required flags
---------------------
-Livepatch relocation sections must be marked with the SHF_RELA_LIVEPATCH
-section flag. See include/uapi/linux/elf.h for the definition. The module
-loader recognizes this flag and will avoid applying those relocation sections
-at patch module load time. These sections must also be marked with SHF_ALLOC,
-so that the module loader doesn't discard them on module load (i.e. they will
-be copied into memory along with the other SHF_ALLOC sections).
-
-2.2.2 Required name format
---------------------------
-The name of a livepatch relocation section must conform to the following format:
-
-.klp.rela.objname.section_name
-^        ^^     ^ ^          ^
-|________||_____| |__________|
-   [A]      [B]        [C]
-
-[A] The relocation section name is prefixed with the string ".klp.rela."
-[B] The name of the object (i.e. "vmlinux" or name of module) to
-    which the relocation section belongs follows immediately after the prefix.
-[C] The actual name of the section to which this relocation section applies.
-
-2.2.3 Example livepatch relocation section names:
--------------------------------------------------
-.klp.rela.ext4.text.ext4_attr_store
-.klp.rela.vmlinux.text.cmdline_proc_show
-

-module that patches vmlinux and modules 9p, btrfs, ext4:

-[*] Livepatch relocation sections are SHT_RELA sections but with a few special
-characteristics. Notice that they are marked SHF_ALLOC ("A") so that they will
-not be discarded when the module is loaded into memory, as well as with the

-[*] Every symbol referenced by a relocation is a livepatch symbol.
-
---------------------
-3. Livepatch symbols
---------------------
-
--------------------------------
-3.1 What are livepatch symbols?
--------------------------------
-Livepatch symbols are symbols referred to by livepatch relocation sections.
-These are symbols accessed from new versions of functions for patched
-objects, whose addresses cannot be resolved by the module loader (because
-they are local or unexported global syms). Since the module loader only
-resolves exported syms, and not every symbol referenced by the new patched
-functions is exported, livepatch symbols were introduced. They are used
-also in cases where we cannot immediately know the address of a symbol when
-a patch module loads. For example, this is the case when livepatch patches
-a module that is not loaded yet. In this case, the relevant livepatch
-symbols are resolved simply when the target module loads. In any case, for
-any livepatch relocation section, all livepatch symbols referenced by that
-section must be resolved before livepatch can call apply_relocate_add() for
-that reloc section.
-
-Livepatch symbols must be marked with SHN_LIVEPATCH so that the module
-loader can identify and ignore them. Livepatch modules keep these symbols
-in their symbol tables, and the symbol table is made accessible through
-module->symtab.
-
--------------------------------------
-3.2 A livepatch module's symbol table
--------------------------------------
-Normally, a stripped down copy of a module's symbol table (containing only
-"core" symbols) is made available through module->symtab (See layout_symtab()
-in kernel/module.c). For livepatch modules, the symbol table copied into memory
-on module load must be exactly the same as the symbol table produced when the
-patch module was compiled. This is because the relocations in each livepatch
-relocation section refer to their respective symbols with their symbol indices,
-and the original symbol indices (and thus the symtab ordering) must be
-preserved in order for apply_relocate_add() to find the right symbol.
-
-For example, take this particular rela from a livepatch module:
-Relocation section '.klp.rela.btrfs.text.btrfs_feature_attr_show' at offset 0x2ba0 contains 4 entries:
-    Offset             Info             Type               Symbol's Value  Symbol's Name + Addend
-000000000000001f  0000005e00000002 R_X86_64_PC32          0000000000000000 .klp.sym.vmlinux.printk,0 - 4
-
-This rela refers to the symbol '.klp.sym.vmlinux.printk,0', and the symbol index is encoded
-in 'Info'. Here its symbol index is 0x5e, which is 94 in decimal, which refers to the
-symbol index 94.
-And in this patch module's corresponding symbol table, symbol index 94 refers to that very symbol:
-[ snip ]
-94: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.printk,0
-[ snip ]
-
----------------------------
-3.3 Livepatch symbol format
----------------------------
-
-3.3.1 Required flags
---------------------
-Livepatch symbols must have their section index marked as SHN_LIVEPATCH, so
-that the module loader can identify them and not attempt to resolve them.
-See include/uapi/linux/elf.h for the actual definitions.
-
-3.3.2 Required name format
---------------------------
-Livepatch symbol names must conform to the following format:
-
-.klp.sym.objname.symbol_name,sympos
-^       ^^     ^ ^         ^ ^
-|_______||_____| |_________| |
-   [A]     [B]       [C]    [D]
-
-[A] The symbol name is prefixed with the string ".klp.sym."
-[B] The name of the object (i.e. "vmlinux" or name of module) to
-    which the symbol belongs follows immediately after the prefix.
-[C] The actual name of the symbol.
-[D] The position of the symbol in the object (as according to kallsyms)
-    This is used to differentiate duplicate symbols within the same
-    object. The symbol position is expressed numerically (0, 1, 2...).
-    The symbol position of a unique symbol is 0.
-
-3.3.3 Example livepatch symbol names:
--------------------------------------
-.klp.sym.vmlinux.snprintf,0
-.klp.sym.vmlinux.printk,0
-.klp.sym.btrfs.btrfs_ktype,0
-
-3.3.4 Example `readelf --symbols` output for a patch module:
-------------------------------------------------------------
-Symbol table '.symtab' contains 127 entries:
-   Num:    Value          Size Type    Bind   Vis     Ndx         Name
-   [ snip ]
-    73: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.snprintf,0
-    74: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.capable,0
-    75: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.find_next_bit,0
-    76: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT OS [0xff20] .klp.sym.vmlinux.si_swapinfo,0
-  [ snip ]                                               ^
-                                                         |
-                                                        [*]
-[*] Note that the 'Ndx' (Section index) for these symbols is SHN_LIVEPATCH (0xff20).
-    "OS" means OS-specific.
-
----------------------------------
-4. Architecture-specific sections
----------------------------------
-Architectures may override arch_klp_init_object_loaded() to perform
-additional arch-specific tasks when a target module loads, such as applying
-arch-specific sections. On x86 for example, we must apply per-object
-.altinstructions and .parainstructions sections when a target module loads.
-These sections must be prefixed with ".klp.arch.$objname." so that they can
-be easily identified when iterating through a patch module's Elf sections
-(See arch/x86/kernel/livepatch.c for a complete example).
-
---------------------------------------
-5. Symbol table and Elf section access
---------------------------------------
-A livepatch module's symbol table is accessible through module->symtab.
-
-Since apply_relocate_add() requires access to a module's section headers,
-symbol table, and relocation section indices, Elf information is preserved for
-livepatch modules and is made accessible by the module loader through
-module->klp_info, which is a klp_modinfo struct. When a livepatch module loads,
-this struct is filled in by the module loader. Its fields are documented below:
-
-struct klp_modinfo {
-	Elf_Ehdr hdr; /* Elf header */
-	Elf_Shdr *sechdrs; /* Section header table */
-	char *secstrings; /* String table for the section headers */
-	unsigned int symndx; /* The symbol table section index */
-};

+================
+Shadow Variables
+================
+
+Shadow variables are a simple way for livepatch modules to associate
+additional "shadow" data with existing data structures.  Shadow data is
+allocated separately from parent data structures, which are left
+unmodified.  The shadow variable API described in this document is used
+to allocate/add and remove/free shadow variables to/from their parents.
+
+The implementation introduces a global, in-kernel hashtable that
+associates pointers to parent objects and a numeric identifier of the
+shadow data.  The numeric identifier is a simple enumeration that may be
+used to describe shadow variable version, class or type, etc.  More
+specifically, the parent pointer serves as the hashtable key while the
+numeric id subsequently filters hashtable queries.  Multiple shadow
+variables may attach to the same parent object, but their numeric
+identifier distinguishes between them.
+
+
+1. Brief API summary
+====================
+
+(See the full API usage docbook notes in livepatch/shadow.c.)
+
+A hashtable references all shadow variables.  These references are
+stored and retrieved through a <obj, id> pair.
+
+* The klp_shadow variable data structure encapsulates both tracking
+  meta-data and shadow-data:
+
+  - meta-data
+
+    - obj - pointer to parent object
+    - id - data identifier
+
+  - data[] - storage for shadow data
+
+It is important to note that the klp_shadow_alloc() and
+klp_shadow_get_or_alloc() are zeroing the variable by default.
+They also allow to call a custom constructor function when a non-zero
+value is needed. Callers should provide whatever mutual exclusion
+is required.
+
+Note that the constructor is called under klp_shadow_lock spinlock. It allows
+to do actions that can be done only once when a new variable is allocated.
+
+* klp_shadow_get() - retrieve a shadow variable data pointer
+  - search hashtable for <obj, id> pair
+
+* klp_shadow_alloc() - allocate and add a new shadow variable
+  - search hashtable for <obj, id> pair
+
+  - if exists
+
+    - WARN and return NULL
+
+  - if <obj, id> doesn't already exist
+
+    - allocate a new shadow variable
+    - initialize the variable using a custom constructor and data when provided
+    - add <obj, id> to the global hashtable
+
+* klp_shadow_get_or_alloc() - get existing or alloc a new shadow variable
+  - search hashtable for <obj, id> pair
+
+  - if exists
+
+    - return existing shadow variable
+
+  - if <obj, id> doesn't already exist
+
+    - allocate a new shadow variable
+    - initialize the variable using a custom constructor and data when provided
+    - add <obj, id> pair to the global hashtable
+
+* klp_shadow_free() - detach and free a <obj, id> shadow variable
+  - find and remove a <obj, id> reference from global hashtable
+
+    - if found
+
+      - call destructor function if defined
+      - free shadow variable
+
+* klp_shadow_free_all() - detach and free all <*, id> shadow variables
+  - find and remove any <*, id> references from global hashtable
+
+    - if found
+
+      - call destructor function if defined
+      - free shadow variable
+
+
+2. Use cases
+============
+
+(See the example shadow variable livepatch modules in samples/livepatch/
+for full working demonstrations.)
+
+For the following use-case examples, consider commit 1d147bfa6429
+("mac80211: fix AP powersave TX vs.  wakeup race"), which added a
+spinlock to net/mac80211/sta_info.h :: struct sta_info.  Each use-case
+example can be considered a stand-alone livepatch implementation of this
+fix.
+
+
+Matching parent's lifecycle
+---------------------------
+
+If parent data structures are frequently created and destroyed, it may
+be easiest to align their shadow variables lifetimes to the same
+allocation and release functions.  In this case, the parent data
+structure is typically allocated, initialized, then registered in some
+manner.  Shadow variable allocation and setup can then be considered
+part of the parent's initialization and should be completed before the
+parent "goes live" (ie, any shadow variable get-API requests are made
+for this <obj, id> pair.)
+
+For commit 1d147bfa6429, when a parent sta_info structure is allocated,
+allocate a shadow copy of the ps_lock pointer, then initialize it::
+
+  #define PS_LOCK 1
+  struct sta_info *sta_info_alloc(struct ieee80211_sub_if_data *sdata,
+				  const u8 *addr, gfp_t gfp)
+  {
+	struct sta_info *sta;
+	spinlock_t *ps_lock;
+
+	/* Parent structure is created */
+	sta = kzalloc(sizeof(*sta) + hw->sta_data_size, gfp);
+
+	/* Attach a corresponding shadow variable, then initialize it */
+	ps_lock = klp_shadow_alloc(sta, PS_LOCK, sizeof(*ps_lock), gfp,
+				   NULL, NULL);
+	if (!ps_lock)
+		goto shadow_fail;
+	spin_lock_init(ps_lock);
+	...
+
+When requiring a ps_lock, query the shadow variable API to retrieve one
+for a specific struct sta_info:::
+
+  void ieee80211_sta_ps_deliver_wakeup(struct sta_info *sta)
+  {
+	spinlock_t *ps_lock;
+
+	/* sync with ieee80211_tx_h_unicast_ps_buf */

-================
-Shadow Variables
-================
-
-Shadow variables are a simple way for livepatch modules to associate
-additional "shadow" data with existing data structures.  Shadow data is
-allocated separately from parent data structures, which are left
-unmodified.  The shadow variable API described in this document is used
-to allocate/add and remove/free shadow variables to/from their parents.
-
-The implementation introduces a global, in-kernel hashtable that
-associates pointers to parent objects and a numeric identifier of the
-shadow data.  The numeric identifier is a simple enumeration that may be
-used to describe shadow variable version, class or type, etc.  More
-specifically, the parent pointer serves as the hashtable key while the
-numeric id subsequently filters hashtable queries.  Multiple shadow
-variables may attach to the same parent object, but their numeric
-identifier distinguishes between them.
-
-
-1. Brief API summary
-====================
-
-(See the full API usage docbook notes in livepatch/shadow.c.)
-
-A hashtable references all shadow variables.  These references are
-stored and retrieved through a <obj, id> pair.
-
-* The klp_shadow variable data structure encapsulates both tracking
-meta-data and shadow-data:
-  - meta-data
-    - obj - pointer to parent object
-    - id - data identifier
-  - data[] - storage for shadow data
-
-It is important to note that the klp_shadow_alloc() and
-klp_shadow_get_or_alloc() are zeroing the variable by default.
-They also allow to call a custom constructor function when a non-zero
-value is needed. Callers should provide whatever mutual exclusion
-is required.
-
-Note that the constructor is called under klp_shadow_lock spinlock. It allows
-to do actions that can be done only once when a new variable is allocated.
-
-* klp_shadow_get() - retrieve a shadow variable data pointer
-  - search hashtable for <obj, id> pair
-
-* klp_shadow_alloc() - allocate and add a new shadow variable
-  - search hashtable for <obj, id> pair
-  - if exists
-    - WARN and return NULL
-  - if <obj, id> doesn't already exist
-    - allocate a new shadow variable
-    - initialize the variable using a custom constructor and data when provided
-    - add <obj, id> to the global hashtable
-
-* klp_shadow_get_or_alloc() - get existing or alloc a new shadow variable
-  - search hashtable for <obj, id> pair
-  - if exists
-    - return existing shadow variable
-  - if <obj, id> doesn't already exist
-    - allocate a new shadow variable
-    - initialize the variable using a custom constructor and data when provided
-    - add <obj, id> pair to the global hashtable
-
-* klp_shadow_free() - detach and free a <obj, id> shadow variable
-  - find and remove a <obj, id> reference from global hashtable
-    - if found
-      - call destructor function if defined
-      - free shadow variable
-
-* klp_shadow_free_all() - detach and free all <*, id> shadow variables
-  - find and remove any <*, id> references from global hashtable
-    - if found
-      - call destructor function if defined
-      - free shadow variable
-
-
-2. Use cases
-============
-
-(See the example shadow variable livepatch modules in samples/livepatch/
-for full working demonstrations.)
-
-For the following use-case examples, consider commit 1d147bfa6429
-("mac80211: fix AP powersave TX vs.  wakeup race"), which added a
-spinlock to net/mac80211/sta_info.h :: struct sta_info.  Each use-case
-example can be considered a stand-alone livepatch implementation of this
-fix.
-
-
-Matching parent's lifecycle
----------------------------
-
-If parent data structures are frequently created and destroyed, it may
-be easiest to align their shadow variables lifetimes to the same
-allocation and release functions.  In this case, the parent data
-structure is typically allocated, initialized, then registered in some
-manner.  Shadow variable allocation and setup can then be considered
-part of the parent's initialization and should be completed before the
-parent "goes live" (ie, any shadow variable get-API requests are made
-for this <obj, id> pair.)
-
-For commit 1d147bfa6429, when a parent sta_info structure is allocated,
-allocate a shadow copy of the ps_lock pointer, then initialize it:
-
-#define PS_LOCK 1
-struct sta_info *sta_info_alloc(struct ieee80211_sub_if_data *sdata,
-				const u8 *addr, gfp_t gfp)
-{
-	struct sta_info *sta;
-	spinlock_t *ps_lock;
-
-	/* Parent structure is created */
-	sta = kzalloc(sizeof(*sta) + hw->sta_data_size, gfp);
-
-	/* Attach a corresponding shadow variable, then initialize it */
-	ps_lock = klp_shadow_alloc(sta, PS_LOCK, sizeof(*ps_lock), gfp,
-				   NULL, NULL);
-	if (!ps_lock)
-		goto shadow_fail;
-	spin_lock_init(ps_lock);
-	...
-
-When requiring a ps_lock, query the shadow variable API to retrieve one
-for a specific struct sta_info:
-
-void ieee80211_sta_ps_deliver_wakeup(struct sta_info *sta)
-{
-	spinlock_t *ps_lock;
-
-	/* sync with ieee80211_tx_h_unicast_ps_buf */
-	ps_lock = klp_shadow_get(sta, PS_LOCK);
-	if (ps_lock)
-		spin_lock(ps_lock);
-	...
-
-When the parent sta_info structure is freed, first free the shadow
-variable:
-
-void sta_info_free(struct ieee80211_local *local, struct sta_info *sta)
-{
-	klp_shadow_free(sta, PS_LOCK, NULL);
-	kfree(sta);
-	...
-
-
-In-flight parent objects
-------------------------
-
-Sometimes it may not be convenient or possible to allocate shadow
-variables alongside their parent objects.  Or a livepatch fix may
-require shadow varibles to only a subset of parent object instances.  In
-these cases, the klp_shadow_get_or_alloc() call can be used to attach
-shadow variables to parents already in-flight.
-
-For commit 1d147bfa6429, a good spot to allocate a shadow spinlock is
-inside ieee80211_sta_ps_deliver_wakeup():
-
-int ps_lock_shadow_ctor(void *obj, void *shadow_data, void *ctor_data)
-{
-	spinlock_t *lock = shadow_data;
-
-	spin_lock_init(lock);
-	return 0;
-}
-
-#define PS_LOCK 1
-void ieee80211_sta_ps_deliver_wakeup(struct sta_info *sta)
-{
-	spinlock_t *ps_lock;
-
-	/* sync with ieee80211_tx_h_unicast_ps_buf */
-	ps_lock = klp_shadow_get_or_alloc(sta, PS_LOCK,
-			sizeof(*ps_lock), GFP_ATOMIC,
-			ps_lock_shadow_ctor, NULL);
-
-	if (ps_lock)
-		spin_lock(ps_lock);
-	...
-
-This usage will create a shadow variable, only if needed, otherwise it
-will use one that was already created for this <obj, id> pair.
-
-Like the previous use-case, the shadow spinlock needs to be cleaned up.
-A shadow variable can be freed just before its parent object is freed,

+Media Controller Device Allocator API
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When the media device belongs to more than one driver, the shared media
+device is allocated with the shared struct device as the key for look ups.
+
+The shared media device should stay in registered state until the last
+driver unregisters it. In addition, the media device should be released when
+all the references are released. Each driver gets a reference to the media
+device during probe, when it allocates the media device. If media device is
+already allocated, the allocate API bumps up the refcount and returns the
+existing media device. The driver puts the reference back in its disconnect
+routine when it calls :c:func:`media_device_delete()`.
+
+The media device is unregistered and cleaned up from the kref put handler to
+ensure that the media device stays in registered state until the last driver
+unregisters the media device.
+
+**Driver Usage**
+
+Drivers should use the appropriate media-core routines to manage the shared
+media device life-time handling the two states:
+1. allocate -> register -> delete
+2. get reference to already registered device -> delete
+
+call :c:func:`media_device_delete()` routine to make sure the shared media
+device delete is handled correctly.
+
+**driver probe:**
+Call :c:func:`media_device_usb_allocate()` to allocate or get a reference
+Call :c:func:`media_device_register()`, if media devnode isn't registered
+
+**driver disconnect:**
+Call :c:func:`media_device_delete()` to free the media_device. Freeing is
+handled by the kref put handler.

-1.1 What the TV decoder can do an what not
-------------------------------------------
-
-The best know TV standards are NTSC/PAL/SECAM. but for decoding a frame that
-information is not enough. There are several formats of the TV standards.
-And not every TV decoder is able to handle every format. Also the every
-combination is supported by the driver. There are currently 11 different
-tv broadcast formats all aver the world.
-
-The CCIR defines parameters needed for broadcasting the signal.
-The CCIR has defined different standards: A,B,D,E,F,G,D,H,I,K,K1,L,M,N,...
-The CCIR says not much about the colorsystem used !!!
-And talking about a colorsystem says not to much about how it is broadcast.
-
-The CCIR standards A,E,F are not used any more.
-
-When you speak about NTSC, you usually mean the standard: CCIR - M using
-the NTSC colorsystem which is used in the USA, Japan, Mexico, Canada
-and a few others.
-
-When you talk about PAL, you usually mean: CCIR - B/G using the PAL
-colorsystem which is used in many Countries.
-
-When you talk about SECAM, you mean: CCIR - L using the SECAM Colorsystem
-which is used in France, and a few others.
-
-There the other version of SECAM, CCIR - D/K is used in Bulgaria, China,
-Slovakai, Hungary, Korea (Rep.), Poland, Rumania and a others.
-
-The CCIR - H uses the PAL colorsystem (sometimes SECAM) and is used in
-Egypt, Libya, Sri Lanka, Syrain Arab. Rep.
-
-The CCIR - I uses the PAL colorsystem, and is used in Great Britain, Hong Kong,
-Ireland, Nigeria, South Africa.
-
-The CCIR - N uses the PAL colorsystem and PAL frame size but the NTSC framerate,
-and is used in Argentinia, Uruguay, an a few others
-
-We do not talk about how the audio is broadcast !
-
-A rather good sites about the TV standards are:
-http://www.sony.jp/support/
-http://info.electronicwerkstatt.de/bereiche/fernsehtechnik/frequenzen_und_normen/Fernsehnormen/
-and http://www.cabl.com/restaurant/channel.html
-
-Other weird things around: NTSC 4.43 is a modificated NTSC, which is mainly
-used in PAL VCR's that are able to play back NTSC. PAL 60 seems to be the same
-as NTSC 4.43 . The Datasheets also talk about NTSC 44, It seems as if it would
-be the same as NTSC 4.43.
-NTSC Combs seems to be a decoder mode where the decoder uses a comb filter
-to split coma and luma instead of a Delay line.
-
-But I did not defiantly find out what NTSC Comb is.

-
-The adv717x, should be able to produce PAL N. But you find nothing PAL N
-specific in the registers. Seem that you have to reuse a other standard
-to generate PAL N, maybe it would work if you use the PAL M settings.
-
-How do I get this damn thing to work
-------------------------------------
-
-Load zr36067.o. If it can't autodetect your card, use the card=X insmod
-option with X being the card number as given in the previous section.
-To have more than one card, use card=X1[,X2[,X3,[X4[..]]]]
-
-To automate this, add the following to your /etc/modprobe.d/zoran.conf:
-
-options zr36067 card=X1[,X2[,X3[,X4[..]]]]
-alias char-major-81-0 zr36067
-
-One thing to keep in mind is that this doesn't load zr36067.o itself yet. It
-just automates loading. If you start using xawtv, the device won't load on
-some systems, since you're trying to load modules as a user, which is not
-allowed ("permission denied"). A quick workaround is to add 'Load "v4l"' to
-XF86Config-4 when you use X by default, or to run 'v4l-conf -c <device>' in
-one of your startup scripts (normally rc.local) if you don't use X. Both
-make sure that the modules are loaded on startup, under the root account.
-
-What mainboard should I use (or why doesn't my card work)
----------------------------------------------------------
-
-
-<insert lousy disclaimer here>. In short: good=SiS/Intel, bad=VIA.
-
-Experience tells us that people with a Buz, on average, have more problems
-than users with a DC10+/LML33. Also, it tells us that people owning a VIA-
-based mainboard (ktXXX, MVP3) have more problems than users with a mainboard
-based on a different chipset. Here's some notes from Andrew Stevens:
-
-Here's my experience of using LML33 and Buz on various motherboards:
-
-- VIA MVP3
-	- Forget it. Pointless. Doesn't work.
-- Intel 430FX (Pentium 200)
-	- LML33 perfect, Buz tolerable (3 or 4 frames dropped per movie)
-- Intel 440BX (early stepping)
-	- LML33 tolerable. Buz starting to get annoying (6-10 frames/hour)
-- Intel 440BX (late stepping)
-	- Buz tolerable, LML3 almost perfect (occasional single frame drops)
-- SiS735
-	- LML33 perfect, Buz tolerable.
-- VIA KT133(*)
-	- LML33 starting to get annoying, Buz poor enough that I have up.
-
-- Both 440BX boards were dual CPU versions.
-
-Bernhard Praschinger later added:
-
-- AMD 751
-	- Buz perfect-tolerable
-- AMD 760
-	- Buz perfect-tolerable
-
-In general, people on the user mailinglist won't give you much of a chance
-if you have a VIA-based motherboard. They may be cheap, but sometimes, you'd
-rather want to spend some more money on better boards. In general, VIA
-mainboard's IDE/PCI performance will also suck badly compared to others.
-You'll noticed the DC10+/DC30+ aren't mentioned anywhere in the overview.
-Basically, you can assume that if the Buz works, the LML33 will work too. If
-the LML33 works, the DC10+/DC30+ will work too. They're most tolerant to
-different mainboard chipsets from all of the supported cards.
-
-If you experience timeouts during capture, buy a better mainboard or lower
-the quality/buffersize during capture (see 'Concerning buffer sizes, quality,
-output size etc.'). If it hangs, there's little we can do as of now. Check
-your IRQs and make sure the card has its own interrupts.
-
-Programming interface
----------------------
-
-This driver conforms to video4linux2. Support for V4L1 and for the custom
-zoran ioctls has been removed in kernel 2.6.38.
-
-For programming example, please, look at lavrec.c and lavplay.c code in
-the MJPEG-tools (http://mjpeg.sf.net/).
-
-Additional notes for software developers:
-
-   The driver returns maxwidth and maxheight parameters according to
-   the current TV standard (norm). Therefore, the software which
-   communicates with the driver and "asks" for these parameters should
-   first set the correct norm. Well, it seems logically correct: TV
-   standard is "more constant" for current country than geometry
-   settings of a variety of TV capture cards which may work in ITU or
-   square pixel format.
-

-
-Concerning buffer sizes, quality, output size etc.
---------------------------------------------------
-
-
-The zr36060 can do 1:2 JPEG compression. This is really the theoretical
-maximum that the chipset can reach. The driver can, however, limit compression
-to a maximum (size) of 1:4. The reason for this is that some cards (e.g. Buz)
-can't handle 1:2 compression without stopping capture after only a few minutes.
-With 1:4, it'll mostly work. If you have a Buz, use 'low_bitrate=1' to go into
-1:4 max. compression mode.
-
-100% JPEG quality is thus 1:2 compression in practice. So for a full PAL frame
-(size 720x576). The JPEG fields are stored in YUY2 format, so the size of the
-fields are 720x288x16/2 bits/field (2 fields/frame) = 207360 bytes/field x 2 =
-414720 bytes/frame (add some more bytes for headers and DHT (huffman)/DQT
-(quantization) tables, and you'll get to something like 512kB per frame for
-1:2 compression. For 1:4 compression, you'd have frames of half this size.
-
-Some additional explanation by Martin Samuelsson, which also explains the
-importance of buffer sizes:
---
-> Hmm, I do not think it is really that way. With the current (downloaded
-> at 18:00 Monday) driver I get that output sizes for 10 sec:
-> -q 50 -b 128 : 24.283.332 Bytes
-> -q 50 -b 256 : 48.442.368
-> -q 25 -b 128 : 24.655.992
-> -q 25 -b 256 : 25.859.820
-
-I woke up, and can't go to sleep again. I'll kill some time explaining why
-this doesn't look strange to me.
-
-Let's do some math using a width of 704 pixels. I'm not sure whether the Buz
-actually use that number or not, but that's not too important right now.
-
-704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block;
-3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block;
-1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum
-output becomes 512 bits per block. Actually 510, but 512 is simpler to use
-for calculations.
-
-Let's say that we specify d1q50. We thus want 256 bits per block; times 3168
-becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes
-here, so we don't need to do any fancy corrections for bits-per-pixel or such
-things. 101376 bytes per field.
-
-d1 video contains two fields per frame. Those sum up to 202752 bytes per
-frame, and one of those frames goes into each buffer.
-
-But wait a second! -b128 gives 128kB buffers! It's not possible to cram
-202752 bytes of JPEG data into 128kB!
-
-This is what the driver notice and automatically compensate for in your
-examples. Let's do some math using this information:
-
-128kB is 131072 bytes. In this buffer, we want to store two fields, which
-leaves 65536 bytes for each field. Using 3168 blocks per field, we get
-20.68686868... available bytes per block; 165 bits. We can't allow the
-request for 256 bits per block when there's only 165 bits available! The -q50
-option is silently overridden, and the -b128 option takes precedence, leaving
-us with the equivalence of -q32.
-
-This gives us a data rate of 165 bits per block, which, times 3168, sums up
-to 65340 bytes per field, out of the allowed 65536. The current driver has
-another level of rate limiting; it won't accept -q values that fill more than
-6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be
-a safe bet. Personally, I think I would have lowered requested-bits-per-block
-by one, or something like that.) We can't use 165 bits per block, but have to
-lower it again, to 6/8 of the available buffer space: We end up with 124 bits
-per block, the equivalence of -q24. With 128kB buffers, you can't use greater
-than -q24 at -d1. (And PAL, and 704 pixels width...)
-
-The third example is limited to -q24 through the same process. The second
-example, using very similar calculations, is limited to -q48. The only
-example that actually grab at the specified -q value is the last one, which
-is clearly visible, looking at the file size.
---
-
-Conclusion: the quality of the resulting movie depends on buffer size, quality,
-whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c
-module to do 1:4 instead of 1:2 compression, etc.
-
-If you experience timeouts, lowering the quality/buffersize or using
-'low_bitrate=1 as insmod option for zr36060.o might actually help, as is
-proven by the Buz.
-
-It hangs/crashes/fails/whatevers! Help!
----------------------------------------
-
-Make sure that the card has its own interrupts (see /proc/interrupts), check
-the output of dmesg at high verbosity (load zr36067.o with debug=2,
-load all other modules with debug=1). Check that your mainboard is favorable
-(see question 2) and if not, test the card in another computer. Also see the
-notes given in question 3 and try lowering quality/buffersize/capturesize
-if recording fails after a period of time.
-
-If all this doesn't help, give a clear description of the problem including
-detailed hardware information (memory+brand, mainboard+chipset+brand, which
-MJPEG card, processor, other PCI cards that might be of interest), give the
-system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give
-the kernel version, driver version, glibc version, gcc version and any other
-information that might possibly be of interest. Also provide the dmesg output
-at high verbosity. See 'Contacting' on how to contact the developers.

 KERNEL I/O BARRIER EFFECTS
 ==========================
 
-When accessing I/O memory, drivers should use the appropriate accessor
-functions:
+Interfacing with peripherals via I/O accesses is deeply architecture and device
+specific. Therefore, drivers which are inherently non-portable may rely on
+specific behaviours of their target systems in order to achieve synchronization
+in the most lightweight manner possible. For drivers intending to be portable
+between multiple architectures and bus implementations, the kernel offers a
+series of accessor functions that provide various degrees of ordering
+guarantees:
 
- (*) inX(), outX():
+ (*) readX(), writeX():
 
-     These are intended to talk to I/O space rather than memory space, but
-     that's primarily a CPU-specific concept.  The i386 and x86_64 processors
-     do indeed have special I/O space access cycles and instructions, but many
-     CPUs don't have such a concept.
+	The readX() and writeX() MMIO accessors take a pointer to the
+	peripheral being accessed as an __iomem * parameter. For pointers
+	mapped with the default I/O attributes (e.g. those returned by
+	ioremap()), the ordering guarantees are as follows:
 
-     The PCI bus, amongst others, defines an I/O space concept which - on such
-     CPUs as i386 and x86_64 - readily maps to the CPU's concept of I/O
-     space.  However, it may also be mapped as a virtual I/O space in the CPU's
-     memory map, particularly on those CPUs that don't support alternate I/O
-     spaces.
+	1. All readX() and writeX() accesses to the same peripheral are ordered
+	   with respect to each other. This ensures that MMIO register accesses
+	   by the same CPU thread to a particular device will arrive in program
+	   order.
 
-     Accesses to this space may be fully synchronous (as on i386), but
-     intermediary bridges (such as the PCI host bridge) may not fully honour
-     that.
+	2. A writeX() issued by a CPU thread holding a spinlock is ordered
+	   before a writeX() to the same peripheral from another CPU thread
+	   issued after a later acquisition of the same spinlock. This ensures
+	   that MMIO register writes to a particular device issued while holding
+	   a spinlock will arrive in an order consistent with acquisitions of
+	   the lock.
 
-     They are guaranteed to be fully ordered with respect to each other.
+	3. A writeX() by a CPU thread to the peripheral will first wait for the
+	   completion of all prior writes to memory either issued by, or
+	   propagated to, the same thread. This ensures that writes by the CPU
+	   to an outbound DMA buffer allocated by dma_alloc_coherent() will be
+	   visible to a DMA engine when the CPU writes to its MMIO control
+	   register to trigger the transfer.
 
-     They are not guaranteed to be fully ordered with respect to other types of
-     memory and I/O operation.
+	4. A readX() by a CPU thread from the peripheral will complete before
+	   any subsequent reads from memory by the same thread can begin. This
+	   ensures that reads by the CPU from an incoming DMA buffer allocated
+	   by dma_alloc_coherent() will not see stale data after reading from
+	   the DMA engine's MMIO status register to establish that the DMA
+	   transfer has completed.
 
- (*) readX(), writeX():
+	5. A readX() by a CPU thread from the peripheral will complete before
+	   any subsequent delay() loop can begin execution on the same thread.
+	   This ensures that two MMIO register writes by the CPU to a peripheral
+	   will arrive at least 1us apart if the first write is immediately read
+	   back with readX() and udelay(1) is called prior to the second
+	   writeX():
 
-     Whether these are guaranteed to be fully ordered and uncombined with
-     respect to each other on the issuing CPU depends on the characteristics
-     defined for the memory window through which they're accessing.  On later
-     i386 architecture machines, for example, this is controlled by way of the
-     MTRR registers.
+		writel(42, DEVICE_REGISTER_0); // Arrives at the device...
+		readl(DEVICE_REGISTER_0);
+		udelay(1);
+		writel(42, DEVICE_REGISTER_1); // ...at least 1us before this.
 
-     Ordinarily, these will be guaranteed to be fully ordered and uncombined,
-     provided they're not accessing a prefetchable device.
+	The ordering properties of __iomem pointers obtained with non-default
+	attributes (e.g. those returned by ioremap_wc()) are specific to the
+	underlying architecture and therefore the guarantees listed above cannot
+	generally be relied upon for accesses to these types of mappings.
 
-     However, intermediary hardware (such as a PCI bridge) may indulge in
-     deferral if it so wishes; to flush a store, a load from the same location
-     is preferred[*], but a load from the same device or from configuration
-     space should suffice for PCI.
+ (*) readX_relaxed(), writeX_relaxed():
 
-     [*] NOTE! attempting to load from the same location as was written to may
-	 cause a malfunction - consider the 16550 Rx/Tx serial registers for
-	 example.
+	These are similar to readX() and writeX(), but provide weaker memory
+	ordering guarantees. Specifically, they do not guarantee ordering with
+	respect to locking, normal memory accesses or delay() loops (i.e.
+	bullets 2-5 above) but they are still guaranteed to be ordered with
+	respect to other accesses from the same CPU thread to the same
+	peripheral when operating on __iomem pointers mapped with the default
+	I/O attributes.
 
-     Used with prefetchable I/O memory, an mmiowb() barrier may be required to
-     force stores to be ordered.
+ (*) readsX(), writesX():
 
-     Please refer to the PCI specification for more information on interactions
-     between PCI transactions.
+	The readsX() and writesX() MMIO accessors are designed for accessing
+	register-based, memory-mapped FIFOs residing on peripherals that are not
+	capable of performing DMA. Consequently, they provide only the ordering
+	guarantees of readX_relaxed() and writeX_relaxed(), as documented above.
 
- (*) readX_relaxed(), writeX_relaxed()
+ (*) inX(), outX():
 
-     These are similar to readX() and writeX(), but provide weaker memory
-     ordering guarantees.  Specifically, they do not guarantee ordering with
-     respect to normal memory accesses (e.g. DMA buffers) nor do they guarantee
-     ordering with respect to LOCK or UNLOCK operations.  If the latter is
-     required, an mmiowb() barrier can be used.  Note that relaxed accesses to
-     the same peripheral are guaranteed to be ordered with respect to each
-     other.
+	The inX() and outX() accessors are intended to access legacy port-mapped
+	I/O peripherals, which may require special instructions on some
+	architectures (notably x86). The port number of the peripheral being
+	accessed is passed as an argument.
 
- (*) ioreadX(), iowriteX()
+	Since many CPU architectures ultimately access these peripherals via an
+	internal virtual memory mapping, the portable ordering guarantees
+	provided by inX() and outX() are the same as those provided by readX()
+	and writeX() respectively when accessing a mapping with the default I/O
+	attributes.
 
-     These will perform appropriately for the type of access they're actually
-     doing, be it inX()/outX() or readX()/writeX().
+	Device drivers may expect outX() to emit a non-posted write transaction
+	that waits for a completion response from the I/O peripheral before
+	returning. This is not guaranteed by all architectures and is therefore
+	not part of the portable ordering semantics.
+
+ (*) insX(), outsX():
+
+	As above, the insX() and outsX() accessors provide the same ordering
+	guarantees as readsX() and writesX() respectively when accessing a
+	mapping with the default I/O attributes.
+
+ (*) ioreadX(), iowriteX():
+
+	These will perform appropriately for the type of access they're actually
+	doing, be it inX()/outX() or readX()/writeX().
+
+With the exception of the string accessors (insX(), outsX(), readsX() and
+writesX()), all of the above assume that the underlying peripheral is
+little-endian and will therefore perform byte-swapping operations on big-endian
+architectures.

-BPF Flow Dissector
-==================
-
-Overview
-========
-
-Flow dissector is a routine that parses metadata out of the packets. It's
-used in the various places in the networking subsystem (RFS, flow hash, etc).
-
-BPF flow dissector is an attempt to reimplement C-based flow dissector logic
-in BPF to gain all the benefits of BPF verifier (namely, limits on the
-number of instructions and tail calls).
-
-API
-===
-
-BPF flow dissector programs operate on an ``__sk_buff``. However, only the
-limited set of fields is allowed: ``data``, ``data_end`` and ``flow_keys``.
-``flow_keys`` is ``struct bpf_flow_keys`` and contains flow dissector input
-and output arguments.
-
-The inputs are:
-  * ``nhoff`` - initial offset of the networking header
-  * ``thoff`` - initial offset of the transport header, initialized to nhoff
-  * ``n_proto`` - L3 protocol type, parsed out of L2 header
-
-Flow dissector BPF program should fill out the rest of the ``struct
-bpf_flow_keys`` fields. Input arguments ``nhoff/thoff/n_proto`` should be
-also adjusted accordingly.
-
-The return code of the BPF program is either BPF_OK to indicate successful
-dissection, or BPF_DROP to indicate parsing error.
-
-__sk_buff->data
-===============
-
-In the VLAN-less case, this is what the initial state of the BPF flow
-dissector looks like::
-
-  +------+------+------------+-----------+
-  | DMAC | SMAC | ETHER_TYPE | L3_HEADER |
-  +------+------+------------+-----------+
-                              ^
-                              |
-                              +-- flow dissector starts here
-
-
-.. code:: c
-
-  skb->data + flow_keys->nhoff point to the first byte of L3_HEADER
-  flow_keys->thoff = nhoff
-  flow_keys->n_proto = ETHER_TYPE
-
-In case of VLAN, flow dissector can be called with the two different states.
-
-Pre-VLAN parsing::
-
-  +------+------+------+-----+-----------+-----------+
-  | DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
-  +------+------+------+-----+-----------+-----------+
-                        ^
-                        |
-                        +-- flow dissector starts here
-
-.. code:: c
-
-  skb->data + flow_keys->nhoff point the to first byte of TCI
-  flow_keys->thoff = nhoff
-  flow_keys->n_proto = TPID
-
-Please note that TPID can be 802.1AD and, hence, BPF program would
-have to parse VLAN information twice for double tagged packets.
-
-
-Post-VLAN parsing::
-
-  +------+------+------+-----+-----------+-----------+
-  | DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
-  +------+------+------+-----+-----------+-----------+
-                                          ^
-                                          |
-                                          +-- flow dissector starts here
-
-.. code:: c
-
-  skb->data + flow_keys->nhoff point the to first byte of L3_HEADER
-  flow_keys->thoff = nhoff
-  flow_keys->n_proto = ETHER_TYPE
-
-In this case VLAN information has been processed before the flow dissector
-and BPF flow dissector is not required to handle it.
-
-
-The takeaway here is as follows: BPF flow dissector program can be called with
-the optional VLAN header and should gracefully handle both cases: when single
-or double VLAN is present and when it is not present. The same program
-can be called for both cases and would have to be written carefully to
-handle both cases.
-
-
-Reference Implementation
-========================
-
-See ``tools/testing/selftests/bpf/progs/bpf_flow.c`` for the reference
-implementation and ``tools/testing/selftests/bpf/flow_dissector_load.[hc]``
-for the loader. bpftool can be used to load BPF flow dissector program as well.
-
-The reference implementation is organized as follows:
-  * ``jmp_table`` map that contains sub-programs for each supported L3 protocol
-  * ``_dissect`` routine - entry point; it does input ``n_proto`` parsing and
-    does ``bpf_tail_call`` to the appropriate L3 handler
-
-Since BPF at this point doesn't support looping (or any jumping back),
-jmp_table is used instead to handle multiple levels of encapsulation (and
-IPv6 options).
-
-
-Current Limitations
-===================

+Broadcom Starfighter 2 Ethernet switch driver
+=============================================
+
+Broadcom's Starfighter 2 Ethernet switch hardware block is commonly found and
+deployed in the following products:
+
+- xDSL gateways such as BCM63138
+- streaming/multimedia Set Top Box such as BCM7445
+- Cable Modem/residential gateways such as BCM7145/BCM3390
+
+The switch is typically deployed in a configuration involving between 5 to 13
+ports, offering a range of built-in and customizable interfaces:
+
+- single integrated Gigabit PHY
+- quad integrated Gigabit PHY
+- quad external Gigabit PHY w/ MDIO multiplexer
+- integrated MoCA PHY
+- several external MII/RevMII/GMII/RGMII interfaces
+
+The switch also supports specific congestion control features which allow MoCA
+fail-over not to lose packets during a MoCA role re-election, as well as out of
+band back-pressure to the host CPU network interface when downstream interfaces
+are connected at a lower speed.
+
+The switch hardware block is typically interfaced using MMIO accesses and
+contains a bunch of sub-blocks/registers:
+
+- ``SWITCH_CORE``: common switch registers
+- ``SWITCH_REG``: external interfaces switch register
+- ``SWITCH_MDIO``: external MDIO bus controller (there is another one in SWITCH_CORE,
+  which is used for indirect PHY accesses)
+- ``SWITCH_INDIR_RW``: 64-bits wide register helper block
+- ``SWITCH_INTRL2_0/1``: Level-2 interrupt controllers
+- ``SWITCH_ACB``: Admission control block
+- ``SWITCH_FCB``: Fail-over control block
+
+Implementation details
+======================
+
+The driver is located in ``drivers/net/dsa/bcm_sf2.c`` and is implemented as a DSA
+driver; see ``Documentation/networking/dsa/dsa.rst`` for details on the subsystem
+and what it provides.
+
+The SF2 switch is configured to enable a Broadcom specific 4-bytes switch tag
+which gets inserted by the switch for every packet forwarded to the CPU
+interface, conversely, the CPU network interface should insert a similar tag for
+packets entering the CPU port. The tag format is described in
+``net/dsa/tag_brcm.c``.
+
+Overall, the SF2 driver is a fairly regular DSA driver; there are a few
+specifics covered below.
+
+Device Tree probing
+-------------------
+
+The DSA platform device driver is probed using a specific compatible string
+provided in ``net/dsa/dsa.c``. The reason for that is because the DSA subsystem gets
+registered as a platform device driver currently. DSA will provide the needed
+device_node pointers which are then accessible by the switch driver setup
+function to setup resources such as register ranges and interrupts. This
+currently works very well because none of the of_* functions utilized by the
+driver require a struct device to be bound to a struct device_node, but things
+may change in the future.
+
+MDIO indirect accesses
+----------------------
+
+Due to a limitation in how Broadcom switches have been designed, external
+Broadcom switches connected to a SF2 require the use of the DSA slave MDIO bus
+in order to properly configure them. By default, the SF2 pseudo-PHY address, and
+an external switch pseudo-PHY address will both be snooping for incoming MDIO
+transactions, since they are at the same address (30), resulting in some kind of
+"double" programming. Using DSA, and setting ``ds->phys_mii_mask`` accordingly, we
+selectively divert reads and writes towards external Broadcom switches
+pseudo-PHY addresses. Newer revisions of the SF2 hardware have introduced a
+configurable pseudo-PHY address which circumvents the initial design limitation.
+
+Multimedia over CoAxial (MoCA) interfaces
+-----------------------------------------
+
+MoCA interfaces are fairly specific and require the use of a firmware blob which
+gets loaded onto the MoCA processor(s) for packet processing. The switch
+hardware contains logic which will assert/de-assert link states accordingly for
+the MoCA interface whenever the MoCA coaxial cable gets disconnected or the
+firmware gets reloaded. The SF2 driver relies on such events to properly set its
+MoCA interface carrier state and properly report this to the networking stack.
+
+The MoCA interfaces are supported using the PHY library's fixed PHY/emulated PHY
+device and the switch driver registers a ``fixed_link_update`` callback for such
+PHYs which reflects the link state obtained from the interrupt handler.
+
+
+Power Management
+----------------
+
+Whenever possible, the SF2 driver tries to minimize the overall switch power
+consumption by applying a combination of:
+
+- turning off internal buffers/memories
+- disabling packet processing logic
+- putting integrated PHYs in IDDQ/low-power
+- reducing the switch core clock based on the active port count
+- enabling and advertising EEE
+- turning off RGMII data processing logic when the link goes down
+
+Wake-on-LAN
+-----------
+
+Wake-on-LAN is currently implemented by utilizing the host processor Ethernet
+MAC controller wake-on logic. Whenever Wake-on-LAN is requested, an intersection
+between the user request and the supported host Ethernet interface WoL
+capabilities is done and the intersection result gets configured. During
+system-wide suspend/resume, only ports not participating in Wake-on-LAN are
+disabled.

+============
+Architecture
+============
+
+This document describes the **Distributed Switch Architecture (DSA)** subsystem
+design principles, limitations, interactions with other subsystems, and how to
+develop drivers for this subsystem as well as a TODO for developers interested
+in joining the effort.
+
+Design principles
+=================
+
+The Distributed Switch Architecture is a subsystem which was primarily designed
+to support Marvell Ethernet switches (MV88E6xxx, a.k.a Linkstreet product line)
+using Linux, but has since evolved to support other vendors as well.
+
+The original philosophy behind this design was to be able to use unmodified
+Linux tools such as bridge, iproute2, ifconfig to work transparently whether
+they configured/queried a switch port network device or a regular network
+device.
+
+An Ethernet switch is typically comprised of multiple front-panel ports, and one
+or more CPU or management port. The DSA subsystem currently relies on the
+presence of a management port connected to an Ethernet controller capable of
+receiving Ethernet frames from the switch. This is a very common setup for all
+kinds of Ethernet switches found in Small Home and Office products: routers,
+gateways, or even top-of-the rack switches. This host Ethernet controller will
+be later referred to as "master" and "cpu" in DSA terminology and code.
+
+The D in DSA stands for Distributed, because the subsystem has been designed
+with the ability to configure and manage cascaded switches on top of each other
+using upstream and downstream Ethernet links between switches. These specific
+ports are referred to as "dsa" ports in DSA terminology and code. A collection
+of multiple switches connected to each other is called a "switch tree".
+
+For each front-panel port, DSA will create specialized network devices which are
+used as controlling and data-flowing endpoints for use by the Linux networking
+stack. These specialized network interfaces are referred to as "slave" network
+interfaces in DSA terminology and code.
+
+The ideal case for using DSA is when an Ethernet switch supports a "switch tag"
+which is a hardware feature making the switch insert a specific tag for each
+Ethernet frames it received to/from specific ports to help the management
+interface figure out:
+
+- what port is this frame coming from
+- what was the reason why this frame got forwarded
+- how to send CPU originated traffic to specific ports
+
+The subsystem does support switches not capable of inserting/stripping tags, but
+the features might be slightly limited in that case (traffic separation relies
+on Port-based VLAN IDs).
+
+Note that DSA does not currently create network interfaces for the "cpu" and
+"dsa" ports because:
+
+- the "cpu" port is the Ethernet switch facing side of the management
+  controller, and as such, would create a duplication of feature, since you
+  would get two interfaces for the same conduit: master netdev, and "cpu" netdev
+
+- the "dsa" port(s) are just conduits between two or more switches, and as such
+  cannot really be used as proper network interfaces either, only the
+  downstream, or the top-most upstream interface makes sense with that model
+
+Switch tagging protocols
+------------------------
+
+DSA currently supports 5 different tagging protocols, and a tag-less mode as
+well. The different protocols are implemented in:
+
+- ``net/dsa/tag_trailer.c``: Marvell's 4 trailer tag mode (legacy)
+- ``net/dsa/tag_dsa.c``: Marvell's original DSA tag
+- ``net/dsa/tag_edsa.c``: Marvell's enhanced DSA tag
+- ``net/dsa/tag_brcm.c``: Broadcom's 4 bytes tag
+- ``net/dsa/tag_qca.c``: Qualcomm's 2 bytes tag
+
+The exact format of the tag protocol is vendor specific, but in general, they
+all contain something which:
+
+- identifies which port the Ethernet frame came from/should be sent to
+- provides a reason why this frame was forwarded to the management interface
+
+Master network devices
+----------------------
+
+Master network devices are regular, unmodified Linux network device drivers for
+the CPU/management Ethernet interface. Such a driver might occasionally need to
+know whether DSA is enabled (e.g.: to enable/disable specific offload features),
+but the DSA subsystem has been proven to work with industry standard drivers:
+``e1000e,`` ``mv643xx_eth`` etc. without having to introduce modifications to these
+drivers. Such network devices are also often referred to as conduit network
+devices since they act as a pipe between the host processor and the hardware
+Ethernet switch.
+
+Networking stack hooks
+----------------------
+
+When a master netdev is used with DSA, a small hook is placed in in the
+networking stack is in order to have the DSA subsystem process the Ethernet
+switch specific tagging protocol. DSA accomplishes this by registering a
+specific (and fake) Ethernet type (later becoming ``skb->protocol``) with the
+networking stack, this is also known as a ``ptype`` or ``packet_type``. A typical
+Ethernet Frame receive sequence looks like this:
+
+Master network device (e.g.: e1000e):
+
+1. Receive interrupt fires:
+
+        - receive function is invoked
+        - basic packet processing is done: getting length, status etc.
+        - packet is prepared to be processed by the Ethernet layer by calling
+          ``eth_type_trans``
+
+2. net/ethernet/eth.c::
+
+          eth_type_trans(skb, dev)
+                  if (dev->dsa_ptr != NULL)
+                          -> skb->protocol = ETH_P_XDSA
+
+3. drivers/net/ethernet/\*::
+
+          netif_receive_skb(skb)
+                  -> iterate over registered packet_type
+                          -> invoke handler for ETH_P_XDSA, calls dsa_switch_rcv()
+
+4. net/dsa/dsa.c::
+
+          -> dsa_switch_rcv()
+                  -> invoke switch tag specific protocol handler in 'net/dsa/tag_*.c'
+
+5. net/dsa/tag_*.c:
+
+        - inspect and strip switch tag protocol to determine originating port
+        - locate per-port network device
+        - invoke ``eth_type_trans()`` with the DSA slave network device
+        - invoked ``netif_receive_skb()``
+
+Past this point, the DSA slave network devices get delivered regular Ethernet
+frames that can be processed by the networking stack.
+
+Slave network devices
+---------------------
+
+Slave network devices created by DSA are stacked on top of their master network
+device, each of these network interfaces will be responsible for being a
+controlling and data-flowing end-point for each front-panel port of the switch.
+These interfaces are specialized in order to:
+
+- insert/remove the switch tag protocol (if it exists) when sending traffic
+  to/from specific switch ports
+- query the switch for ethtool operations: statistics, link state,
+  Wake-on-LAN, register dumps...
+- external/internal PHY management: link, auto-negotiation etc.
+
+These slave network devices have custom net_device_ops and ethtool_ops function
+pointers which allow DSA to introduce a level of layering between the networking
+stack/ethtool, and the switch driver implementation.
+
+Upon frame transmission from these slave network devices, DSA will look up which
+switch tagging protocol is currently registered with these network devices, and
+invoke a specific transmit routine which takes care of adding the relevant
+switch tag in the Ethernet frames.
+
+These frames are then queued for transmission using the master network device
+``ndo_start_xmit()`` function, since they contain the appropriate switch tag, the
+Ethernet switch will be able to process these incoming frames from the
+management interface and delivers these frames to the physical switch port.
+
+Graphical representation
+------------------------
+
+Summarized, this is basically how DSA looks like from a network device
+perspective::
+
+
+                |---------------------------
+                | CPU network device (eth0)|
+                ----------------------------

+                |        tag added by CPU> |
+        |--------------------------------------------|
+        |            Switch driver                   |
+        |--------------------------------------------|
+                  ||        ||         ||
+              |-------|  |-------|  |-------|
+              | sw0p0 |  | sw0p1 |  | sw0p2 |
+              |-------|  |-------|  |-------|
+
+
+
+Slave MDIO bus
+--------------
+
+In order to be able to read to/from a switch PHY built into it, DSA creates a
+slave MDIO bus which allows a specific switch driver to divert and intercept
+MDIO reads/writes towards specific PHY addresses. In most MDIO-connected
+switches, these functions would utilize direct or indirect PHY addressing mode
+to return standard MII registers from the switch builtin PHYs, allowing the PHY
+library and/or to return link status, link partner pages, auto-negotiation
+results etc..
+
+For Ethernet switches which have both external and internal MDIO busses, the
+slave MII bus can be utilized to mux/demux MDIO reads and writes towards either
+internal or external MDIO devices this switch might be connected to: internal
+PHYs, external PHYs, or even external switches.
+
+Data structures
+---------------
+
+DSA data structures are defined in ``include/net/dsa.h`` as well as
+``net/dsa/dsa_priv.h``:
+
+- ``dsa_chip_data``: platform data configuration for a given switch device,
+  this structure describes a switch device's parent device, its address, as
+  well as various properties of its ports: names/labels, and finally a routing
+  table indication (when cascading switches)
+
+- ``dsa_platform_data``: platform device configuration data which can reference
+  a collection of dsa_chip_data structure if multiples switches are cascaded,
+  the master network device this switch tree is attached to needs to be
+  referenced
+
+- ``dsa_switch_tree``: structure assigned to the master network device under
+  ``dsa_ptr``, this structure references a dsa_platform_data structure as well as
+  the tagging protocol supported by the switch tree, and which receive/transmit
+  function hooks should be invoked, information about the directly attached
+  switch is also provided: CPU port. Finally, a collection of dsa_switch are
+  referenced to address individual switches in the tree.
+
+- ``dsa_switch``: structure describing a switch device in the tree, referencing
+  a ``dsa_switch_tree`` as a backpointer, slave network devices, master network
+  device, and a reference to the backing``dsa_switch_ops``
+
+- ``dsa_switch_ops``: structure referencing function pointers, see below for a
+  full description.
+
+Design limitations
+==================
+
+Limits on the number of devices and ports
+-----------------------------------------
+
+DSA currently limits the number of maximum switches within a tree to 4
+(``DSA_MAX_SWITCHES``), and the number of ports per switch to 12 (``DSA_MAX_PORTS``).
+These limits could be extended to support larger configurations would this need
+arise.
+
+Lack of CPU/DSA network devices
+-------------------------------
+
+DSA does not currently create slave network devices for the CPU or DSA ports, as
+described before. This might be an issue in the following cases:
+
+- inability to fetch switch CPU port statistics counters using ethtool, which
+  can make it harder to debug MDIO switch connected using xMII interfaces
+
+- inability to configure the CPU port link parameters based on the Ethernet
+  controller capabilities attached to it: http://patchwork.ozlabs.org/patch/509806/
+
+- inability to configure specific VLAN IDs / trunking VLANs between switches
+  when using a cascaded setup
+
+Common pitfalls using DSA setups
+--------------------------------
+
+Once a master network device is configured to use DSA (dev->dsa_ptr becomes
+non-NULL), and the switch behind it expects a tagging protocol, this network
+interface can only exclusively be used as a conduit interface. Sending packets
+directly through this interface (e.g.: opening a socket using this interface)
+will not make us go through the switch tagging protocol transmit function, so
+the Ethernet switch on the other end, expecting a tag will typically drop this
+frame.
+
+Slave network devices check that the master network device is UP before allowing
+you to administratively bring UP these slave network devices. A common
+configuration mistake is forgetting to bring UP the master network device first.
+
+Interactions with other subsystems
+==================================
+
+DSA currently leverages the following subsystems:
+
+- MDIO/PHY library: ``drivers/net/phy/phy.c``, ``mdio_bus.c``
+- Switchdev:``net/switchdev/*``
+- Device Tree for various of_* functions
+
+MDIO/PHY library
+----------------
+
+Slave network devices exposed by DSA may or may not be interfacing with PHY
+devices (``struct phy_device`` as defined in ``include/linux/phy.h)``, but the DSA
+subsystem deals with all possible combinations:
+
+- internal PHY devices, built into the Ethernet switch hardware
+- external PHY devices, connected via an internal or external MDIO bus
+- internal PHY devices, connected via an internal MDIO bus
+- special, non-autonegotiated or non MDIO-managed PHY devices: SFPs, MoCA; a.k.a
+  fixed PHYs
+
+The PHY configuration is done by the ``dsa_slave_phy_setup()`` function and the
+logic basically looks like this:
+
+- if Device Tree is used, the PHY device is looked up using the standard
+  "phy-handle" property, if found, this PHY device is created and registered
+  using ``of_phy_connect()``
+
+- if Device Tree is used, and the PHY device is "fixed", that is, conforms to
+  the definition of a non-MDIO managed PHY as defined in
+  ``Documentation/devicetree/bindings/net/fixed-link.txt``, the PHY is registered
+  and connected transparently using the special fixed MDIO bus driver
+
+- finally, if the PHY is built into the switch, as is very common with
+  standalone switch packages, the PHY is probed using the slave MII bus created
+  by DSA
+
+
+SWITCHDEV
+---------
+
+DSA directly utilizes SWITCHDEV when interfacing with the bridge layer, and
+more specifically with its VLAN filtering portion when configuring VLANs on top
+of per-port slave network devices. Since DSA primarily deals with
+MDIO-connected switches, although not exclusively, SWITCHDEV's
+prepare/abort/commit phases are often simplified into a prepare phase which
+checks whether the operation is supported by the DSA switch driver, and a commit
+phase which applies the changes.
+
+As of today, the only SWITCHDEV objects supported by DSA are the FDB and VLAN
+objects.
+
+Device Tree
+-----------
+
+DSA features a standardized binding which is documented in
+``Documentation/devicetree/bindings/net/dsa/dsa.txt``. PHY/MDIO library helper
+functions such as ``of_get_phy_mode()``, ``of_phy_connect()`` are also used to query
+per-port PHY specific details: interface connection, MDIO bus location etc..
+
+Driver development
+==================
+
+DSA switch drivers need to implement a dsa_switch_ops structure which will
+contain the various members described below.
+
+``register_switch_driver()`` registers this dsa_switch_ops in its internal list
+of drivers to probe for. ``unregister_switch_driver()`` does the exact opposite.
+
+Unless requested differently by setting the priv_size member accordingly, DSA
+does not allocate any driver private context space.
+
+Switch configuration
+--------------------
+
+- ``tag_protocol``: this is to indicate what kind of tagging protocol is supported,
+  should be a valid value from the ``dsa_tag_protocol`` enum
+
+- ``probe``: probe routine which will be invoked by the DSA platform device upon
+  registration to test for the presence/absence of a switch device. For MDIO
+  devices, it is recommended to issue a read towards internal registers using
+  the switch pseudo-PHY and return whether this is a supported device. For other
+  buses, return a non-NULL string
+
+- ``setup``: setup function for the switch, this function is responsible for setting
+  up the ``dsa_switch_ops`` private structure with all it needs: register maps,
+  interrupts, mutexes, locks etc.. This function is also expected to properly
+  configure the switch to separate all network interfaces from each other, that
+  is, they should be isolated by the switch hardware itself, typically by creating
+  a Port-based VLAN ID for each port and allowing only the CPU port and the
+  specific port to be in the forwarding vector. Ports that are unused by the
+  platform should be disabled. Past this function, the switch is expected to be
+  fully configured and ready to serve any kind of request. It is recommended
+  to issue a software reset of the switch during this setup function in order to
+  avoid relying on what a previous software agent such as a bootloader/firmware
+  may have previously configured.
+
+PHY devices and link management
+-------------------------------
+
+- ``get_phy_flags``: Some switches are interfaced to various kinds of Ethernet PHYs,
+  if the PHY library PHY driver needs to know about information it cannot obtain
+  on its own (e.g.: coming from switch memory mapped registers), this function
+  should return a 32-bits bitmask of "flags", that is private between the switch
+  driver and the Ethernet PHY driver in ``drivers/net/phy/\*``.
+
+- ``phy_read``: Function invoked by the DSA slave MDIO bus when attempting to read
+  the switch port MDIO registers. If unavailable, return 0xffff for each read.
+  For builtin switch Ethernet PHYs, this function should allow reading the link
+  status, auto-negotiation results, link partner pages etc..
+
+- ``phy_write``: Function invoked by the DSA slave MDIO bus when attempting to write
+  to the switch port MDIO registers. If unavailable return a negative error
+  code.
+
+- ``adjust_link``: Function invoked by the PHY library when a slave network device
+  is attached to a PHY device. This function is responsible for appropriately
+  configuring the switch port link parameters: speed, duplex, pause based on
+  what the ``phy_device`` is providing.
+
+- ``fixed_link_update``: Function invoked by the PHY library, and specifically by
+  the fixed PHY driver asking the switch driver for link parameters that could
+  not be auto-negotiated, or obtained by reading the PHY registers through MDIO.
+  This is particularly useful for specific kinds of hardware such as QSGMII,
+  MoCA or other kinds of non-MDIO managed PHYs where out of band link
+  information is obtained
+
+Ethtool operations
+------------------
+
+- ``get_strings``: ethtool function used to query the driver's strings, will
+  typically return statistics strings, private flags strings etc.
+
+- ``get_ethtool_stats``: ethtool function used to query per-port statistics and
+  return their values. DSA overlays slave network devices general statistics:
+  RX/TX counters from the network device, with switch driver specific statistics
+  per port
+
+- ``get_sset_count``: ethtool function used to query the number of statistics items
+
+- ``get_wol``: ethtool function used to obtain Wake-on-LAN settings per-port, this
+  function may, for certain implementations also query the master network device
+  Wake-on-LAN settings if this interface needs to participate in Wake-on-LAN
+
+- ``set_wol``: ethtool function used to configure Wake-on-LAN settings per-port,
+  direct counterpart to set_wol with similar restrictions
+
+- ``set_eee``: ethtool function which is used to configure a switch port EEE (Green
+  Ethernet) settings, can optionally invoke the PHY library to enable EEE at the
+  PHY level if relevant. This function should enable EEE at the switch port MAC
+  controller and data-processing logic
+
+- ``get_eee``: ethtool function which is used to query a switch port EEE settings,
+  this function should return the EEE state of the switch port MAC controller
+  and data-processing logic as well as query the PHY for its currently configured
+  EEE settings
+
+- ``get_eeprom_len``: ethtool function returning for a given switch the EEPROM
+  length/size in bytes
+
+- ``get_eeprom``: ethtool function returning for a given switch the EEPROM contents
+
+- ``set_eeprom``: ethtool function writing specified data to a given switch EEPROM
+
+- ``get_regs_len``: ethtool function returning the register length for a given
+  switch
+
+- ``get_regs``: ethtool function returning the Ethernet switch internal register
+  contents. This function might require user-land code in ethtool to
+  pretty-print register values and registers
+
+Power management
+----------------
+
+- ``suspend``: function invoked by the DSA platform device when the system goes to
+  suspend, should quiesce all Ethernet switch activities, but keep ports
+  participating in Wake-on-LAN active as well as additional wake-up logic if
+  supported
+
+- ``resume``: function invoked by the DSA platform device when the system resumes,
+  should resume all Ethernet switch activities and re-configure the switch to be
+  in a fully active state
+
+- ``port_enable``: function invoked by the DSA slave network device ndo_open
+  function when a port is administratively brought up, this function should be
+  fully enabling a given switch port. DSA takes care of marking the port with
+  ``BR_STATE_BLOCKING`` if the port is a bridge member, or ``BR_STATE_FORWARDING`` if it
+  was not, and propagating these changes down to the hardware
+
+- ``port_disable``: function invoked by the DSA slave network device ndo_close
+  function when a port is administratively brought down, this function should be
+  fully disabling a given switch port. DSA takes care of marking the port with
+  ``BR_STATE_DISABLED`` and propagating changes to the hardware if this port is
+  disabled while being a bridge member
+
+Bridge layer
+------------
+
+- ``port_bridge_join``: bridge layer function invoked when a given switch port is
+  added to a bridge, this function should be doing the necessary at the switch
+  level to permit the joining port from being added to the relevant logical
+  domain for it to ingress/egress traffic with other members of the bridge.
+
+- ``port_bridge_leave``: bridge layer function invoked when a given switch port is
+  removed from a bridge, this function should be doing the necessary at the
+  switch level to deny the leaving port from ingress/egress traffic from the
+  remaining bridge members. When the port leaves the bridge, it should be aged
+  out at the switch hardware for the switch to (re) learn MAC addresses behind
+  this port.
+
+- ``port_stp_state_set``: bridge layer function invoked when a given switch port STP
+  state is computed by the bridge layer and should be propagated to switch
+  hardware to forward/block/learn traffic. The switch driver is responsible for
+  computing a STP state change based on current and asked parameters and perform
+  the relevant ageing based on the intersection results
+
+Bridge VLAN filtering
+---------------------
+
+- ``port_vlan_filtering``: bridge layer function invoked when the bridge gets
+  configured for turning on or off VLAN filtering. If nothing specific needs to
+  be done at the hardware level, this callback does not need to be implemented.
+  When VLAN filtering is turned on, the hardware must be programmed with
+  rejecting 802.1Q frames which have VLAN IDs outside of the programmed allowed
+  VLAN ID map/rules.  If there is no PVID programmed into the switch port,
+  untagged frames must be rejected as well. When turned off the switch must
+  accept any 802.1Q frames irrespective of their VLAN ID, and untagged frames are
+  allowed.
+
+- ``port_vlan_prepare``: bridge layer function invoked when the bridge prepares the
+  configuration of a VLAN on the given port. If the operation is not supported
+  by the hardware, this function should return ``-EOPNOTSUPP`` to inform the bridge
+  code to fallback to a software implementation. No hardware setup must be done
+  in this function. See port_vlan_add for this and details.
+
+- ``port_vlan_add``: bridge layer function invoked when a VLAN is configured
+  (tagged or untagged) for the given switch port
+
+- ``port_vlan_del``: bridge layer function invoked when a VLAN is removed from the
+  given switch port
+
+- ``port_vlan_dump``: bridge layer function invoked with a switchdev callback
+  function that the driver has to call for each VLAN the given port is a member
+  of. A switchdev object is used to carry the VID and bridge flags.
+
+- ``port_fdb_add``: bridge layer function invoked when the bridge wants to install a
+  Forwarding Database entry, the switch hardware should be programmed with the
+  specified address in the specified VLAN Id in the forwarding database
+  associated with this VLAN ID. If the operation is not supported, this
+  function should return ``-EOPNOTSUPP`` to inform the bridge code to fallback to
+  a software implementation.
+
+.. note:: VLAN ID 0 corresponds to the port private database, which, in the context
+        of DSA, would be the its port-based VLAN, used by the associated bridge device.
+
+- ``port_fdb_del``: bridge layer function invoked when the bridge wants to remove a
+  Forwarding Database entry, the switch hardware should be programmed to delete
+  the specified MAC address from the specified VLAN ID if it was mapped into
+  this port forwarding database
+
+- ``port_fdb_dump``: bridge layer function invoked with a switchdev callback
+  function that the driver has to call for each MAC address known to be behind
+  the given port. A switchdev object is used to carry the VID and FDB info.
+
+- ``port_mdb_prepare``: bridge layer function invoked when the bridge prepares the
+  installation of a multicast database entry. If the operation is not supported,
+  this function should return ``-EOPNOTSUPP`` to inform the bridge code to fallback
+  to a software implementation. No hardware setup must be done in this function.
+  See ``port_fdb_add`` for this and details.
+
+- ``port_mdb_add``: bridge layer function invoked when the bridge wants to install
+  a multicast database entry, the switch hardware should be programmed with the
+  specified address in the specified VLAN ID in the forwarding database
+  associated with this VLAN ID.
+
+.. note:: VLAN ID 0 corresponds to the port private database, which, in the context
+        of DSA, would be the its port-based VLAN, used by the associated bridge device.
+
+- ``port_mdb_del``: bridge layer function invoked when the bridge wants to remove a
+  multicast database entry, the switch hardware should be programmed to delete
+  the specified MAC address from the specified VLAN ID if it was mapped into
+  this port forwarding database.
+
+- ``port_mdb_dump``: bridge layer function invoked with a switchdev callback
+  function that the driver has to call for each MAC address known to be behind
+  the given port. A switchdev object is used to carry the VID and MDB info.
+
+TODO
+====
+
+Making SWITCHDEV and DSA converge towards an unified codebase
+-------------------------------------------------------------
+
+SWITCHDEV properly takes care of abstracting the networking stack with offload
+capable hardware, but does not enforce a strict switch device driver model. On
+the other DSA enforces a fairly strict device driver model, and deals with most
+of the switch specific. At some point we should envision a merger between these
+two subsystems and get the best of both worlds.
+
+Other hanging fruits

-Distributed Switch Architecture
-===============================
-
-Introduction
-============
-
-This document describes the Distributed Switch Architecture (DSA) subsystem
-design principles, limitations, interactions with other subsystems, and how to
-develop drivers for this subsystem as well as a TODO for developers interested
-in joining the effort.
-
-Design principles
-=================
-
-The Distributed Switch Architecture is a subsystem which was primarily designed
-to support Marvell Ethernet switches (MV88E6xxx, a.k.a Linkstreet product line)
-using Linux, but has since evolved to support other vendors as well.
-
-The original philosophy behind this design was to be able to use unmodified
-Linux tools such as bridge, iproute2, ifconfig to work transparently whether
-they configured/queried a switch port network device or a regular network
-device.
-
-An Ethernet switch is typically comprised of multiple front-panel ports, and one
-or more CPU or management port. The DSA subsystem currently relies on the
-presence of a management port connected to an Ethernet controller capable of
-receiving Ethernet frames from the switch. This is a very common setup for all
-kinds of Ethernet switches found in Small Home and Office products: routers,
-gateways, or even top-of-the rack switches. This host Ethernet controller will
-be later referred to as "master" and "cpu" in DSA terminology and code.
-
-The D in DSA stands for Distributed, because the subsystem has been designed
-with the ability to configure and manage cascaded switches on top of each other
-using upstream and downstream Ethernet links between switches. These specific
-ports are referred to as "dsa" ports in DSA terminology and code. A collection
-of multiple switches connected to each other is called a "switch tree".
-
-For each front-panel port, DSA will create specialized network devices which are
-used as controlling and data-flowing endpoints for use by the Linux networking
-stack. These specialized network interfaces are referred to as "slave" network
-interfaces in DSA terminology and code.
-
-The ideal case for using DSA is when an Ethernet switch supports a "switch tag"
-which is a hardware feature making the switch insert a specific tag for each
-Ethernet frames it received to/from specific ports to help the management
-interface figure out:
-
-- what port is this frame coming from
-- what was the reason why this frame got forwarded
-- how to send CPU originated traffic to specific ports
-
-The subsystem does support switches not capable of inserting/stripping tags, but
-the features might be slightly limited in that case (traffic separation relies
-on Port-based VLAN IDs).
-
-Note that DSA does not currently create network interfaces for the "cpu" and
-"dsa" ports because:
-
-- the "cpu" port is the Ethernet switch facing side of the management
-  controller, and as such, would create a duplication of feature, since you
-  would get two interfaces for the same conduit: master netdev, and "cpu" netdev
-
-- the "dsa" port(s) are just conduits between two or more switches, and as such
-  cannot really be used as proper network interfaces either, only the
-  downstream, or the top-most upstream interface makes sense with that model
-
-Switch tagging protocols
-------------------------
-
-DSA currently supports 5 different tagging protocols, and a tag-less mode as
-well. The different protocols are implemented in:
-
-net/dsa/tag_trailer.c: Marvell's 4 trailer tag mode (legacy)
-net/dsa/tag_dsa.c: Marvell's original DSA tag
-net/dsa/tag_edsa.c: Marvell's enhanced DSA tag
-net/dsa/tag_brcm.c: Broadcom's 4 bytes tag
-net/dsa/tag_qca.c: Qualcomm's 2 bytes tag
-
-The exact format of the tag protocol is vendor specific, but in general, they
-all contain something which:
-
-- identifies which port the Ethernet frame came from/should be sent to
-- provides a reason why this frame was forwarded to the management interface
-
-Master network devices
-----------------------
-
-Master network devices are regular, unmodified Linux network device drivers for
-the CPU/management Ethernet interface. Such a driver might occasionally need to
-know whether DSA is enabled (e.g.: to enable/disable specific offload features),
-but the DSA subsystem has been proven to work with industry standard drivers:
-e1000e, mv643xx_eth etc. without having to introduce modifications to these
-drivers. Such network devices are also often referred to as conduit network
-devices since they act as a pipe between the host processor and the hardware
-Ethernet switch.
-
-Networking stack hooks
-----------------------
-
-When a master netdev is used with DSA, a small hook is placed in in the
-networking stack is in order to have the DSA subsystem process the Ethernet
-switch specific tagging protocol. DSA accomplishes this by registering a
-specific (and fake) Ethernet type (later becoming skb->protocol) with the
-networking stack, this is also known as a ptype or packet_type. A typical
-Ethernet Frame receive sequence looks like this:
-
-Master network device (e.g.: e1000e):
-
-Receive interrupt fires:
-- receive function is invoked
-- basic packet processing is done: getting length, status etc.
-- packet is prepared to be processed by the Ethernet layer by calling
-  eth_type_trans
-
-net/ethernet/eth.c:
-
-eth_type_trans(skb, dev)
-	if (dev->dsa_ptr != NULL)
-		-> skb->protocol = ETH_P_XDSA
-
-drivers/net/ethernet/*:
-
-netif_receive_skb(skb)
-	-> iterate over registered packet_type
-		-> invoke handler for ETH_P_XDSA, calls dsa_switch_rcv()
-
-net/dsa/dsa.c:
-	-> dsa_switch_rcv()
-		-> invoke switch tag specific protocol handler in
-		   net/dsa/tag_*.c
-
-net/dsa/tag_*.c:
-	-> inspect and strip switch tag protocol to determine originating port
-	-> locate per-port network device
-	-> invoke eth_type_trans() with the DSA slave network device
-	-> invoked netif_receive_skb()
-
-Past this point, the DSA slave network devices get delivered regular Ethernet
-frames that can be processed by the networking stack.
-
-Slave network devices
----------------------
-
-Slave network devices created by DSA are stacked on top of their master network
-device, each of these network interfaces will be responsible for being a
-controlling and data-flowing end-point for each front-panel port of the switch.
-These interfaces are specialized in order to:
-
-- insert/remove the switch tag protocol (if it exists) when sending traffic
-  to/from specific switch ports
-- query the switch for ethtool operations: statistics, link state,
-  Wake-on-LAN, register dumps...
-- external/internal PHY management: link, auto-negotiation etc.
-
-These slave network devices have custom net_device_ops and ethtool_ops function
-pointers which allow DSA to introduce a level of layering between the networking
-stack/ethtool, and the switch driver implementation.
-
-Upon frame transmission from these slave network devices, DSA will look up which
-switch tagging protocol is currently registered with these network devices, and
-invoke a specific transmit routine which takes care of adding the relevant
-switch tag in the Ethernet frames.
-
-These frames are then queued for transmission using the master network device
-ndo_start_xmit() function, since they contain the appropriate switch tag, the
-Ethernet switch will be able to process these incoming frames from the
-management interface and delivers these frames to the physical switch port.
-
-Graphical representation
-------------------------
-
-Summarized, this is basically how DSA looks like from a network device
-perspective:
-
-
-			|---------------------------
-			| CPU network device (eth0)|
-			----------------------------
-			| <tag added by switch     |
-			|                          |
-			|                          |
-			|        tag added by CPU> |
-		|--------------------------------------------|
-		| Switch driver				     |
-		|--------------------------------------------|
-                    ||        ||         ||
-		|-------|  |-------|  |-------|
-		| sw0p0 |  | sw0p1 |  | sw0p2 |
-		|-------|  |-------|  |-------|
-
-Slave MDIO bus
---------------
-
-In order to be able to read to/from a switch PHY built into it, DSA creates a
-slave MDIO bus which allows a specific switch driver to divert and intercept
-MDIO reads/writes towards specific PHY addresses. In most MDIO-connected
-switches, these functions would utilize direct or indirect PHY addressing mode
-to return standard MII registers from the switch builtin PHYs, allowing the PHY
-library and/or to return link status, link partner pages, auto-negotiation
-results etc..
-
-For Ethernet switches which have both external and internal MDIO busses, the
-slave MII bus can be utilized to mux/demux MDIO reads and writes towards either
-internal or external MDIO devices this switch might be connected to: internal
-PHYs, external PHYs, or even external switches.
-
-Data structures
----------------
-
-DSA data structures are defined in include/net/dsa.h as well as
-net/dsa/dsa_priv.h.
-
-dsa_chip_data: platform data configuration for a given switch device, this
-structure describes a switch device's parent device, its address, as well as
-various properties of its ports: names/labels, and finally a routing table
-indication (when cascading switches)
-
-dsa_platform_data: platform device configuration data which can reference a
-collection of dsa_chip_data structure if multiples switches are cascaded, the
-master network device this switch tree is attached to needs to be referenced
-
-dsa_switch_tree: structure assigned to the master network device under
-"dsa_ptr", this structure references a dsa_platform_data structure as well as
-the tagging protocol supported by the switch tree, and which receive/transmit
-function hooks should be invoked, information about the directly attached switch
-is also provided: CPU port. Finally, a collection of dsa_switch are referenced
-to address individual switches in the tree.
-
-dsa_switch: structure describing a switch device in the tree, referencing a
-dsa_switch_tree as a backpointer, slave network devices, master network device,
-and a reference to the backing dsa_switch_ops
-
-dsa_switch_ops: structure referencing function pointers, see below for a full
-description.
-
-Design limitations
-==================
-
-Limits on the number of devices and ports
------------------------------------------
-
-DSA currently limits the number of maximum switches within a tree to 4
-(DSA_MAX_SWITCHES), and the number of ports per switch to 12 (DSA_MAX_PORTS).
-These limits could be extended to support larger configurations would this need
-arise.
-
-Lack of CPU/DSA network devices
--------------------------------
-
-DSA does not currently create slave network devices for the CPU or DSA ports, as
-described before. This might be an issue in the following cases:
-
-- inability to fetch switch CPU port statistics counters using ethtool, which
-  can make it harder to debug MDIO switch connected using xMII interfaces
-
-- inability to configure the CPU port link parameters based on the Ethernet
-  controller capabilities attached to it: http://patchwork.ozlabs.org/patch/509806/
-
-- inability to configure specific VLAN IDs / trunking VLANs between switches
-  when using a cascaded setup
-
-Common pitfalls using DSA setups
---------------------------------
-
-Once a master network device is configured to use DSA (dev->dsa_ptr becomes
-non-NULL), and the switch behind it expects a tagging protocol, this network
-interface can only exclusively be used as a conduit interface. Sending packets
-directly through this interface (e.g.: opening a socket using this interface)
-will not make us go through the switch tagging protocol transmit function, so
-the Ethernet switch on the other end, expecting a tag will typically drop this
-frame.
-
-Slave network devices check that the master network device is UP before allowing
-you to administratively bring UP these slave network devices. A common
-configuration mistake is forgetting to bring UP the master network device first.
-
-Interactions with other subsystems
-==================================
-
-DSA currently leverages the following subsystems:
-
-- MDIO/PHY library: drivers/net/phy/phy.c, mdio_bus.c
-- Switchdev: net/switchdev/*
-- Device Tree for various of_* functions
-
-MDIO/PHY library
-----------------
-
-Slave network devices exposed by DSA may or may not be interfacing with PHY
-devices (struct phy_device as defined in include/linux/phy.h), but the DSA
-subsystem deals with all possible combinations:
-
-- internal PHY devices, built into the Ethernet switch hardware
-- external PHY devices, connected via an internal or external MDIO bus
-- internal PHY devices, connected via an internal MDIO bus
-- special, non-autonegotiated or non MDIO-managed PHY devices: SFPs, MoCA; a.k.a
-  fixed PHYs
-
-The PHY configuration is done by the dsa_slave_phy_setup() function and the
-logic basically looks like this:
-
-- if Device Tree is used, the PHY device is looked up using the standard
-  "phy-handle" property, if found, this PHY device is created and registered
-  using of_phy_connect()
-
-- if Device Tree is used, and the PHY device is "fixed", that is, conforms to
-  the definition of a non-MDIO managed PHY as defined in
-  Documentation/devicetree/bindings/net/fixed-link.txt, the PHY is registered
-  and connected transparently using the special fixed MDIO bus driver
-
-- finally, if the PHY is built into the switch, as is very common with
-  standalone switch packages, the PHY is probed using the slave MII bus created
-  by DSA
-
-
-SWITCHDEV
----------
-
-DSA directly utilizes SWITCHDEV when interfacing with the bridge layer, and
-more specifically with its VLAN filtering portion when configuring VLANs on top
-of per-port slave network devices. Since DSA primarily deals with
-MDIO-connected switches, although not exclusively, SWITCHDEV's
-prepare/abort/commit phases are often simplified into a prepare phase which
-checks whether the operation is supported by the DSA switch driver, and a commit
-phase which applies the changes.
-
-As of today, the only SWITCHDEV objects supported by DSA are the FDB and VLAN
-objects.
-
-Device Tree
------------
-
-DSA features a standardized binding which is documented in
-Documentation/devicetree/bindings/net/dsa/dsa.txt. PHY/MDIO library helper
-functions such as of_get_phy_mode(), of_phy_connect() are also used to query
-per-port PHY specific details: interface connection, MDIO bus location etc..
-
-Driver development
-==================
-
-DSA switch drivers need to implement a dsa_switch_ops structure which will
-contain the various members described below.
-
-register_switch_driver() registers this dsa_switch_ops in its internal list
-of drivers to probe for. unregister_switch_driver() does the exact opposite.
-
-Unless requested differently by setting the priv_size member accordingly, DSA
-does not allocate any driver private context space.
-
-Switch configuration
---------------------
-
-- tag_protocol: this is to indicate what kind of tagging protocol is supported,
-  should be a valid value from the dsa_tag_protocol enum
-
-- probe: probe routine which will be invoked by the DSA platform device upon
-  registration to test for the presence/absence of a switch device. For MDIO
-  devices, it is recommended to issue a read towards internal registers using
-  the switch pseudo-PHY and return whether this is a supported device. For other
-  buses, return a non-NULL string
-
-- setup: setup function for the switch, this function is responsible for setting
-  up the dsa_switch_ops private structure with all it needs: register maps,
-  interrupts, mutexes, locks etc.. This function is also expected to properly
-  configure the switch to separate all network interfaces from each other, that
-  is, they should be isolated by the switch hardware itself, typically by creating
-  a Port-based VLAN ID for each port and allowing only the CPU port and the
-  specific port to be in the forwarding vector. Ports that are unused by the
-  platform should be disabled. Past this function, the switch is expected to be
-  fully configured and ready to serve any kind of request. It is recommended
-  to issue a software reset of the switch during this setup function in order to
-  avoid relying on what a previous software agent such as a bootloader/firmware
-  may have previously configured.
-
-PHY devices and link management
--------------------------------
-
-- get_phy_flags: Some switches are interfaced to various kinds of Ethernet PHYs,
-  if the PHY library PHY driver needs to know about information it cannot obtain
-  on its own (e.g.: coming from switch memory mapped registers), this function
-  should return a 32-bits bitmask of "flags", that is private between the switch
-  driver and the Ethernet PHY driver in drivers/net/phy/*.
-
-- phy_read: Function invoked by the DSA slave MDIO bus when attempting to read
-  the switch port MDIO registers. If unavailable, return 0xffff for each read.
-  For builtin switch Ethernet PHYs, this function should allow reading the link
-  status, auto-negotiation results, link partner pages etc..
-
-- phy_write: Function invoked by the DSA slave MDIO bus when attempting to write
-  to the switch port MDIO registers. If unavailable return a negative error
-  code.
-
-- adjust_link: Function invoked by the PHY library when a slave network device
-  is attached to a PHY device. This function is responsible for appropriately
-  configuring the switch port link parameters: speed, duplex, pause based on
-  what the phy_device is providing.
-
-- fixed_link_update: Function invoked by the PHY library, and specifically by
-  the fixed PHY driver asking the switch driver for link parameters that could
-  not be auto-negotiated, or obtained by reading the PHY registers through MDIO.
-  This is particularly useful for specific kinds of hardware such as QSGMII,
-  MoCA or other kinds of non-MDIO managed PHYs where out of band link
-  information is obtained
-
-Ethtool operations
-------------------
-
-- get_strings: ethtool function used to query the driver's strings, will
-  typically return statistics strings, private flags strings etc.
-
-- get_ethtool_stats: ethtool function used to query per-port statistics and
-  return their values. DSA overlays slave network devices general statistics:
-  RX/TX counters from the network device, with switch driver specific statistics
-  per port
-
-- get_sset_count: ethtool function used to query the number of statistics items
-
-- get_wol: ethtool function used to obtain Wake-on-LAN settings per-port, this
-  function may, for certain implementations also query the master network device
-  Wake-on-LAN settings if this interface needs to participate in Wake-on-LAN
-
-- set_wol: ethtool function used to configure Wake-on-LAN settings per-port,
-  direct counterpart to set_wol with similar restrictions
-
-- set_eee: ethtool function which is used to configure a switch port EEE (Green
-  Ethernet) settings, can optionally invoke the PHY library to enable EEE at the
-  PHY level if relevant. This function should enable EEE at the switch port MAC
-  controller and data-processing logic
-
-- get_eee: ethtool function which is used to query a switch port EEE settings,
-  this function should return the EEE state of the switch port MAC controller
-  and data-processing logic as well as query the PHY for its currently configured
-  EEE settings
-
-- get_eeprom_len: ethtool function returning for a given switch the EEPROM
-  length/size in bytes
-
-- get_eeprom: ethtool function returning for a given switch the EEPROM contents
-
-- set_eeprom: ethtool function writing specified data to a given switch EEPROM
-
-- get_regs_len: ethtool function returning the register length for a given
-  switch
-
-- get_regs: ethtool function returning the Ethernet switch internal register
-  contents. This function might require user-land code in ethtool to
-  pretty-print register values and registers
-
-Power management
-----------------
-
-- suspend: function invoked by the DSA platform device when the system goes to
-  suspend, should quiesce all Ethernet switch activities, but keep ports
-  participating in Wake-on-LAN active as well as additional wake-up logic if
-  supported
-
-- resume: function invoked by the DSA platform device when the system resumes,
-  should resume all Ethernet switch activities and re-configure the switch to be
-  in a fully active state
-
-- port_enable: function invoked by the DSA slave network device ndo_open
-  function when a port is administratively brought up, this function should be
-  fully enabling a given switch port. DSA takes care of marking the port with
-  BR_STATE_BLOCKING if the port is a bridge member, or BR_STATE_FORWARDING if it
-  was not, and propagating these changes down to the hardware
-
-- port_disable: function invoked by the DSA slave network device ndo_close
-  function when a port is administratively brought down, this function should be
-  fully disabling a given switch port. DSA takes care of marking the port with
-  BR_STATE_DISABLED and propagating changes to the hardware if this port is
-  disabled while being a bridge member
-
-Bridge layer
-------------
-
-- port_bridge_join: bridge layer function invoked when a given switch port is
-  added to a bridge, this function should be doing the necessary at the switch
-  level to permit the joining port from being added to the relevant logical
-  domain for it to ingress/egress traffic with other members of the bridge.
-
-- port_bridge_leave: bridge layer function invoked when a given switch port is
-  removed from a bridge, this function should be doing the necessary at the
-  switch level to deny the leaving port from ingress/egress traffic from the
-  remaining bridge members. When the port leaves the bridge, it should be aged
-  out at the switch hardware for the switch to (re) learn MAC addresses behind
-  this port.
-
-- port_stp_state_set: bridge layer function invoked when a given switch port STP
-  state is computed by the bridge layer and should be propagated to switch
-  hardware to forward/block/learn traffic. The switch driver is responsible for
-  computing a STP state change based on current and asked parameters and perform
-  the relevant ageing based on the intersection results
-
-Bridge VLAN filtering
----------------------
-
-- port_vlan_filtering: bridge layer function invoked when the bridge gets
-  configured for turning on or off VLAN filtering. If nothing specific needs to
-  be done at the hardware level, this callback does not need to be implemented.
-  When VLAN filtering is turned on, the hardware must be programmed with
-  rejecting 802.1Q frames which have VLAN IDs outside of the programmed allowed
-  VLAN ID map/rules.  If there is no PVID programmed into the switch port,
-  untagged frames must be rejected as well. When turned off the switch must
-  accept any 802.1Q frames irrespective of their VLAN ID, and untagged frames are
-  allowed.
-
-- port_vlan_prepare: bridge layer function invoked when the bridge prepares the
-  configuration of a VLAN on the given port. If the operation is not supported
-  by the hardware, this function should return -EOPNOTSUPP to inform the bridge
-  code to fallback to a software implementation. No hardware setup must be done
-  in this function. See port_vlan_add for this and details.
-
-- port_vlan_add: bridge layer function invoked when a VLAN is configured
-  (tagged or untagged) for the given switch port
-
-- port_vlan_del: bridge layer function invoked when a VLAN is removed from the
-  given switch port
-
-- port_vlan_dump: bridge layer function invoked with a switchdev callback
-  function that the driver has to call for each VLAN the given port is a member
-  of. A switchdev object is used to carry the VID and bridge flags.
-
-- port_fdb_add: bridge layer function invoked when the bridge wants to install a
-  Forwarding Database entry, the switch hardware should be programmed with the
-  specified address in the specified VLAN Id in the forwarding database
-  associated with this VLAN ID. If the operation is not supported, this
-  function should return -EOPNOTSUPP to inform the bridge code to fallback to
-  a software implementation.
-
-Note: VLAN ID 0 corresponds to the port private database, which, in the context
-of DSA, would be the its port-based VLAN, used by the associated bridge device.
-
-- port_fdb_del: bridge layer function invoked when the bridge wants to remove a
-  Forwarding Database entry, the switch hardware should be programmed to delete
-  the specified MAC address from the specified VLAN ID if it was mapped into
-  this port forwarding database
-
-- port_fdb_dump: bridge layer function invoked with a switchdev callback
-  function that the driver has to call for each MAC address known to be behind
-  the given port. A switchdev object is used to carry the VID and FDB info.
-
-- port_mdb_prepare: bridge layer function invoked when the bridge prepares the
-  installation of a multicast database entry. If the operation is not supported,
-  this function should return -EOPNOTSUPP to inform the bridge code to fallback
-  to a software implementation. No hardware setup must be done in this function.
-  See port_fdb_add for this and details.
-
-- port_mdb_add: bridge layer function invoked when the bridge wants to install
-  a multicast database entry, the switch hardware should be programmed with the
-  specified address in the specified VLAN ID in the forwarding database
-  associated with this VLAN ID.
-
-Note: VLAN ID 0 corresponds to the port private database, which, in the context
-of DSA, would be the its port-based VLAN, used by the associated bridge device.
-
-- port_mdb_del: bridge layer function invoked when the bridge wants to remove a
-  multicast database entry, the switch hardware should be programmed to delete
-  the specified MAC address from the specified VLAN ID if it was mapped into
-  this port forwarding database.
-
-- port_mdb_dump: bridge layer function invoked with a switchdev callback
-  function that the driver has to call for each MAC address known to be behind
-  the given port. A switchdev object is used to carry the VID and MDB info.

-
-Making SWITCHDEV and DSA converge towards an unified codebase
--------------------------------------------------------------
-
-SWITCHDEV properly takes care of abstracting the networking stack with offload
-capable hardware, but does not enforce a strict switch device driver model. On
-the other DSA enforces a fairly strict device driver model, and deals with most
-of the switch specific. At some point we should envision a merger between these
-two subsystems and get the best of both worlds.

-Other hanging fruits

+NXP SJA1105 switch driver
+=========================
+
+Overview
+========
+
+The NXP SJA1105 is a family of 6 devices:
+
+- SJA1105E: First generation, no TTEthernet
+- SJA1105T: First generation, TTEthernet
+- SJA1105P: Second generation, no TTEthernet, no SGMII
+- SJA1105Q: Second generation, TTEthernet, no SGMII
+- SJA1105R: Second generation, no TTEthernet, SGMII
+- SJA1105S: Second generation, TTEthernet, SGMII
+
+These are SPI-managed automotive switches, with all ports being gigabit
+capable, and supporting MII/RMII/RGMII and optionally SGMII on one port.
+
+Being automotive parts, their configuration interface is geared towards
+set-and-forget use, with minimal dynamic interaction at runtime. They
+require a static configuration to be composed by software and packed
+with CRC and table headers, and sent over SPI.
+
+The static configuration is composed of several configuration tables. Each
+table takes a number of entries. Some configuration tables can be (partially)
+reconfigured at runtime, some not. Some tables are mandatory, some not:
+
+============================= ================== =============================

+============================= ================== =============================
+
+
+Also the configuration is write-only (software cannot read it back from the
+switch except for very few exceptions).
+
+The driver creates a static configuration at probe time, and keeps it at
+all times in memory, as a shadow for the hardware state. When required to
+change a hardware setting, the static configuration is also updated.
+If that changed setting can be transmitted to the switch through the dynamic
+reconfiguration interface, it is; otherwise the switch is reset and
+reprogrammed with the updated static configuration.
+
+Traffic support
+===============
+
+The switches do not support switch tagging in hardware. But they do support
+customizing the TPID by which VLAN traffic is identified as such. The switch
+driver is leveraging ``CONFIG_NET_DSA_TAG_8021Q`` by requesting that special
+VLANs (with a custom TPID of ``ETH_P_EDSA`` instead of ``ETH_P_8021Q``) are
+installed on its ports when not in ``vlan_filtering`` mode. This does not
+interfere with the reception and transmission of real 802.1Q-tagged traffic,
+because the switch does no longer parse those packets as VLAN after the TPID
+change.
+The TPID is restored when ``vlan_filtering`` is requested by the user through
+the bridge layer, and general IP termination becomes no longer possible through
+the switch netdevices in this mode.
+
+The switches have two programmable filters for link-local destination MACs.
+These are used to trap BPDUs and PTP traffic to the master netdevice, and are
+further used to support STP and 1588 ordinary clock/boundary clock
+functionality.
+
+The following traffic modes are supported over the switch netdevices:
+
++--------------------+------------+------------------+------------------+
+|                    | Standalone |   Bridged with   |   Bridged with   |
+|                    |    ports   | vlan_filtering 0 | vlan_filtering 1 |
++====================+============+==================+==================+
+| Regular traffic    |     Yes    |       Yes        |  No (use master) |
++--------------------+------------+------------------+------------------+
+| Management traffic |     Yes    |       Yes        |       Yes        |
+|    (BPDU, PTP)     |            |                  |                  |
++--------------------+------------+------------------+------------------+
+
+Switching features
+==================
+
+The driver supports the configuration of L2 forwarding rules in hardware for
+port bridging. The forwarding, broadcast and flooding domain between ports can
+be restricted through two methods: either at the L2 forwarding level (isolate
+one bridge's ports from another's) or at the VLAN port membership level
+(isolate ports within the same bridge). The final forwarding decision taken by
+the hardware is a logical AND of these two sets of rules.
+
+The hardware tags all traffic internally with a port-based VLAN (pvid), or it
+decodes the VLAN information from the 802.1Q tag. Advanced VLAN classification
+is not possible. Once attributed a VLAN tag, frames are checked against the
+port's membership rules and dropped at ingress if they don't match any VLAN.
+This behavior is available when switch ports are enslaved to a bridge with
+``vlan_filtering 1``.
+
+Normally the hardware is not configurable with respect to VLAN awareness, but
+by changing what TPID the switch searches 802.1Q tags for, the semantics of a
+bridge with ``vlan_filtering 0`` can be kept (accept all traffic, tagged or
+untagged), and therefore this mode is also supported.
+
+Segregating the switch ports in multiple bridges is supported (e.g. 2 + 2), but
+all bridges should have the same level of VLAN awareness (either both have
+``vlan_filtering`` 0, or both 1). Also an inevitable limitation of the fact
+that VLAN awareness is global at the switch level is that once a bridge with
+``vlan_filtering`` enslaves at least one switch port, the other un-bridged
+ports are no longer available for standalone traffic termination.
+
+Topology and loop detection through STP is supported.
+
+L2 FDB manipulation (add/delete/dump) is currently possible for the first
+generation devices. Aging time of FDB entries, as well as enabling fully static
+management (no address learning and no flooding of unknown traffic) is not yet
+configurable in the driver.
+
+A special comment about bridging with other netdevices (illustrated with an
+example):
+
+A board has eth0, eth1, swp0@eth1, swp1@eth1, swp2@eth1, swp3@eth1.
+The switch ports (swp0-3) are under br0.
+It is desired that eth0 is turned into another switched port that communicates
+with swp0-3.
+
+If br0 has vlan_filtering 0, then eth0 can simply be added to br0 with the
+intended results.
+If br0 has vlan_filtering 1, then a new br1 interface needs to be created that
+enslaves eth0 and eth1 (the DSA master of the switch ports). This is because in
+this mode, the switch ports beneath br0 are not capable of regular traffic, and
+are only used as a conduit for switchdev operations.
+
+Device Tree bindings and board design
+=====================================
+
+This section references ``Documentation/devicetree/bindings/net/dsa/sja1105.txt``
+and aims to showcase some potential switch caveats.
+
+RMII PHY role and out-of-band signaling
+---------------------------------------
+
+In the RMII spec, the 50 MHz clock signals are either driven by the MAC or by
+an external oscillator (but not by the PHY).
+But the spec is rather loose and devices go outside it in several ways.
+Some PHYs go against the spec and may provide an output pin where they source
+the 50 MHz clock themselves, in an attempt to be helpful.
+On the other hand, the SJA1105 is only binary configurable - when in the RMII
+MAC role it will also attempt to drive the clock signal. To prevent this from
+happening it must be put in RMII PHY role.
+But doing so has some unintended consequences.
+In the RMII spec, the PHY can transmit extra out-of-band signals via RXD[1:0].
+These are practically some extra code words (/J/ and /K/) sent prior to the
+preamble of each frame. The MAC does not have this out-of-band signaling
+mechanism defined by the RMII spec.
+So when the SJA1105 port is put in PHY role to avoid having 2 drivers on the
+clock signal, inevitably an RMII PHY-to-PHY connection is created. The SJA1105
+emulates a PHY interface fully and generates the /J/ and /K/ symbols prior to
+frame preambles, which the real PHY is not expected to understand. So the PHY
+simply encodes the extra symbols received from the SJA1105-as-PHY onto the
+100Base-Tx wire.
+On the other side of the wire, some link partners might discard these extra
+symbols, while others might choke on them and discard the entire Ethernet
+frames that follow along. This looks like packet loss with some link partners
+but not with others.
+The take-away is that in RMII mode, the SJA1105 must be let to drive the
+reference clock if connected to a PHY.
+
+RGMII fixed-link and internal delays
+------------------------------------
+
+As mentioned in the bindings document, the second generation of devices has
+tunable delay lines as part of the MAC, which can be used to establish the
+correct RGMII timing budget.
+When powered up, these can shift the Rx and Tx clocks with a phase difference
+between 73.8 and 101.7 degrees.
+The catch is that the delay lines need to lock onto a clock signal with a
+stable frequency. This means that there must be at least 2 microseconds of
+silence between the clock at the old vs at the new frequency. Otherwise the
+lock is lost and the delay lines must be reset (powered down and back up).
+In RGMII the clock frequency changes with link speed (125 MHz at 1000 Mbps, 25
+MHz at 100 Mbps and 2.5 MHz at 10 Mbps), and link speed might change during the
+AN process.
+In the situation where the switch port is connected through an RGMII fixed-link
+to a link partner whose link state life cycle is outside the control of Linux
+(such as a different SoC), then the delay lines would remain unlocked (and
+inactive) until there is manual intervention (ifdown/ifup on the switch port).
+The take-away is that in RGMII mode, the switch's internal delays are only
+reliable if the link partner never changes link speeds, or if it does, it does
+so in a way that is coordinated with the switch port (practically, both ends of
+the fixed-link are under control of the same Linux system).
+As to why would a fixed-link interface ever change link speeds: there are
+Ethernet controllers out there which come out of reset in 100 Mbps mode, and
+their driver inevitably needs to change the speed and clock frequency if it's
+required to work at gigabit.
+
+MDIO bus and PHY management
+---------------------------
+
+The SJA1105 does not have an MDIO bus and does not perform in-band AN either.
+Therefore there is no link state notification coming from the switch device.
+A board would need to hook up the PHYs connected to the switch to any other
+MDIO bus available to Linux within the system (e.g. to the DSA master's MDIO
+bus). Link state management then works by the driver manually keeping in sync
+(over SPI commands) the MAC link speed with the settings negotiated by the PHY.

+==================
+
+Kernel TLS operation
+====================
+
+Linux kernel provides TLS connection offload infrastructure. Once a TCP
+connection is in ``ESTABLISHED`` state user space can enable the TLS Upper
+Layer Protocol (ULP) and install the cryptographic connection state.
+For details regarding the user-facing interface refer to the TLS
+documentation in :ref:`Documentation/networking/tls.rst <kernel_tls>`.
+
+``ktls`` can operate in three modes:
+
+ * Software crypto mode (``TLS_SW``) - CPU handles the cryptography.
+   In most basic cases only crypto operations synchronous with the CPU
+   can be used, but depending on calling context CPU may utilize
+   asynchronous crypto accelerators. The use of accelerators introduces extra
+   latency on socket reads (decryption only starts when a read syscall
+   is made) and additional I/O load on the system.
+ * Packet-based NIC offload mode (``TLS_HW``) - the NIC handles crypto
+   on a packet by packet basis, provided the packets arrive in order.
+   This mode integrates best with the kernel stack and is described in detail
+   in the remaining part of this document
+   (``ethtool`` flags ``tls-hw-tx-offload`` and ``tls-hw-rx-offload``).
+ * Full TCP NIC offload mode (``TLS_HW_RECORD``) - mode of operation where
+   NIC driver and firmware replace the kernel networking stack
+   with its own TCP handling, it is not usable in production environments
+   making use of the Linux networking stack for example any firewalling
+   abilities or QoS and packet scheduling (``ethtool`` flag ``tls-hw-record``).
+
+The operation mode is selected automatically based on device configuration,
+offload opt-in or opt-out on per-connection basis is not currently supported.
+
+TX
+--
+
+At a high level user write requests are turned into a scatter list, the TLS ULP
+intercepts them, inserts record framing, performs encryption (in ``TLS_SW``
+mode) and then hands the modified scatter list to the TCP layer. From this
+point on the TCP stack proceeds as normal.
+
+In ``TLS_HW`` mode the encryption is not performed in the TLS ULP.
+Instead packets reach a device driver, the driver will mark the packets
+for crypto offload based on the socket the packet is attached to,
+and send them to the device for encryption and transmission.
+
+RX
+--
+
+On the receive side if the device handled decryption and authentication
+successfully, the driver will set the decrypted bit in the associated
+:c:type:`struct sk_buff <sk_buff>`. The packets reach the TCP stack and
+are handled normally. ``ktls`` is informed when data is queued to the socket
+and the ``strparser`` mechanism is used to delineate the records. Upon read
+request, records are retrieved from the socket and passed to decryption routine.
+If device decrypted all the segments of the record the decryption is skipped,
+otherwise software path handles decryption.

+
+   Layers of Kernel TLS stack
+
+Device configuration
+====================
+
+During driver initialization device sets the ``NETIF_F_HW_TLS_RX`` and
+``NETIF_F_HW_TLS_TX`` features and installs its
+:c:type:`struct tlsdev_ops <tlsdev_ops>`
+pointer in the :c:member:`tlsdev_ops` member of the
+:c:type:`struct net_device <net_device>`.
+
+When TLS cryptographic connection state is installed on a ``ktls`` socket
+(note that it is done twice, once for RX and once for TX direction,
+and the two are completely independent), the kernel checks if the underlying
+network device is offload-capable and attempts the offload. In case offload
+fails the connection is handled entirely in software using the same mechanism
+as if the offload was never tried.
+
+Offload request is performed via the :c:member:`tls_dev_add` callback of
+:c:type:`struct tlsdev_ops <tlsdev_ops>`:
+
+.. code-block:: c
+
+	int (*tls_dev_add)(struct net_device *netdev, struct sock *sk,
+			   enum tls_offload_ctx_dir direction,
+			   struct tls_crypto_info *crypto_info,
+			   u32 start_offload_tcp_sn);
+
+``direction`` indicates whether the cryptographic information is for
+the received or transmitted packets. Driver uses the ``sk`` parameter
+to retrieve the connection 5-tuple and socket family (IPv4 vs IPv6).
+Cryptographic information in ``crypto_info`` includes the key, iv, salt
+as well as TLS record sequence number. ``start_offload_tcp_sn`` indicates
+which TCP sequence number corresponds to the beginning of the record with
+sequence number from ``crypto_info``. The driver can add its state
+at the end of kernel structures (see :c:member:`driver_state` members
+in ``include/net/tls.h``) to avoid additional allocations and pointer
+dereferences.
+
+TX
+--
+
+After TX state is installed, the stack guarantees that the first segment
+of the stream will start exactly at the ``start_offload_tcp_sn`` sequence
+number, simplifying TCP sequence number matching.
+
+TX offload being fully initialized does not imply that all segments passing
+through the driver and which belong to the offloaded socket will be after
+the expected sequence number and will have kernel record information.
+In particular, already encrypted data may have been queued to the socket
+before installing the connection state in the kernel.
+
+RX
+--
+
+In RX direction local networking stack has little control over the segmentation,
+so the initial records' TCP sequence number may be anywhere inside the segment.
+
+Normal operation
+================
+
+At the minimum the device maintains the following state for each connection, in
+each direction:
+
+ * crypto secrets (key, iv, salt)
+ * crypto processing state (partial blocks, partial authentication tag, etc.)
+ * record metadata (sequence number, processing offset and length)
+ * expected TCP sequence number
+
+There are no guarantees on record length or record segmentation. In particular
+segments may start at any point of a record and contain any number of records.
+Assuming segments are received in order, the device should be able to perform
+crypto operations and authentication regardless of segmentation. For this
+to be possible device has to keep small amount of segment-to-segment state.
+This includes at least:
+
+ * partial headers (if a segment carried only a part of the TLS header)
+ * partial data block
+ * partial authentication tag (all data had been seen but part of the
+   authentication tag has to be written or read from the subsequent segment)
+
+Record reassembly is not necessary for TLS offload. If the packets arrive
+in order the device should be able to handle them separately and make
+forward progress.
+
+TX
+--
+
+The kernel stack performs record framing reserving space for the authentication
+tag and populating all other TLS header and tailer fields.
+
+Both the device and the driver maintain expected TCP sequence numbers
+due to the possibility of retransmissions and the lack of software fallback
+once the packet reaches the device.
+For segments passed in order, the driver marks the packets with
+a connection identifier (note that a 5-tuple lookup is insufficient to identify
+packets requiring HW offload, see the :ref:`5tuple_problems` section)
+and hands them to the device. The device identifies the packet as requiring
+TLS handling and confirms the sequence number matches its expectation.
+The device performs encryption and authentication of the record data.
+It replaces the authentication tag and TCP checksum with correct values.
+
+RX
+--
+
+Before a packet is DMAed to the host (but after NIC's embedded switching
+and packet transformation functions) the device validates the Layer 4
+checksum and performs a 5-tuple lookup to find any TLS connection the packet
+may belong to (technically a 4-tuple
+lookup is sufficient - IP addresses and TCP port numbers, as the protocol
+is always TCP). If connection is matched device confirms if the TCP sequence
+number is the expected one and proceeds to TLS handling (record delineation,
+decryption, authentication for each record in the packet). The device leaves
+the record framing unmodified, the stack takes care of record decapsulation.
+Device indicates successful handling of TLS offload in the per-packet context
+(descriptor) passed to the host.
+
+Upon reception of a TLS offloaded packet, the driver sets
+the :c:member:`decrypted` mark in :c:type:`struct sk_buff <sk_buff>`
+corresponding to the segment. Networking stack makes sure decrypted
+and non-decrypted segments do not get coalesced (e.g. by GRO or socket layer)
+and takes care of partial decryption.
+
+Resync handling
+===============
+
+In presence of packet drops or network packet reordering, the device may lose
+synchronization with the TLS stream, and require a resync with the kernel's
+TCP stack.
+
+Note that resync is only attempted for connections which were successfully
+added to the device table and are in TLS_HW mode. For example,
+if the table was full when cryptographic state was installed in the kernel,
+such connection will never get offloaded. Therefore the resync request
+does not carry any cryptographic connection state.
+
+TX
+--
+
+Segments transmitted from an offloaded socket can get out of sync
+in similar ways to the receive side-retransmissions - local drops
+are possible, though network reorders are not.
+
+Whenever an out of order segment is transmitted the driver provides
+the device with enough information to perform cryptographic operations.
+This means most likely that the part of the record preceding the current
+segment has to be passed to the device as part of the packet context,
+together with its TCP sequence number and TLS record number. The device
+can then initialize its crypto state, process and discard the preceding
+data (to be able to insert the authentication tag) and move onto handling
+the actual packet.
+
+In this mode depending on the implementation the driver can either ask
+for a continuation with the crypto state and the new sequence number
+(next expected segment is the one after the out of order one), or continue
+with the previous stream state - assuming that the out of order segment
+was just a retransmission. The former is simpler, and does not require
+retransmission detection therefore it is the recommended method until
+such time it is proven inefficient.
+
+RX
+--
+
+A small amount of RX reorder events may not require a full resynchronization.
+In particular the device should not lose synchronization
+when record boundary can be recovered:
+
+.. kernel-figure::  tls-offload-reorder-good.svg
+   :alt:	reorder of non-header segment
+   :align:	center
+
+   Reorder of non-header segment
+
+Green segments are successfully decrypted, blue ones are passed
+as received on wire, red stripes mark start of new records.
+
+In above case segment 1 is received and decrypted successfully.
+Segment 2 was dropped so 3 arrives out of order. The device knows
+the next record starts inside 3, based on record length in segment 1.
+Segment 3 is passed untouched, because due to lack of data from segment 2
+the remainder of the previous record inside segment 3 cannot be handled.
+The device can, however, collect the authentication algorithm's state
+and partial block from the new record in segment 3 and when 4 and 5
+arrive continue decryption. Finally when 2 arrives it's completely outside
+of expected window of the device so it's passed as is without special
+handling. ``ktls`` software fallback handles the decryption of record
+spanning segments 1, 2 and 3. The device did not get out of sync,
+even though two segments did not get decrypted.
+
+Kernel synchronization may be necessary if the lost segment contained
+a record header and arrived after the next record header has already passed:
+
+.. kernel-figure::  tls-offload-reorder-bad.svg
+   :alt:	reorder of header segment
+   :align:	center
+
+   Reorder of segment with a TLS header
+
+In this example segment 2 gets dropped, and it contains a record header.
+Device can only detect that segment 4 also contains a TLS header
+if it knows the length of the previous record from segment 2. In this case
+the device will lose synchronization with the stream.
+
+When the device gets out of sync and the stream reaches TCP sequence
+numbers more than a max size record past the expected TCP sequence number,
+the device starts scanning for a known header pattern. For example
+for TLS 1.2 and TLS 1.3 subsequent bytes of value ``0x03 0x03`` occur
+in the SSL/TLS version field of the header. Once pattern is matched
+the device continues attempting parsing headers at expected locations
+(based on the length fields at guessed locations).
+Whenever the expected location does not contain a valid header the scan
+is restarted.
+
+When the header is matched the device sends a confirmation request
+to the kernel, asking if the guessed location is correct (if a TLS record
+really starts there), and which record sequence number the given header had.
+The kernel confirms the guessed location was correct and tells the device
+the record sequence number. Meanwhile, the device had been parsing
+and counting all records since the just-confirmed one, it adds the number
+of records it had seen to the record number provided by the kernel.
+At this point the device is in sync and can resume decryption at next
+segment boundary.
+
+In a pathological case the device may latch onto a sequence of matching
+headers and never hear back from the kernel (there is no negative
+confirmation from the kernel). The implementation may choose to periodically
+restart scan. Given how unlikely falsely-matching stream is, however,
+periodic restart is not deemed necessary.
+
+Special care has to be taken if the confirmation request is passed
+asynchronously to the packet stream and record may get processed
+by the kernel before the confirmation request.
+
+Error handling
+==============
+
+TX
+--
+
+Packets may be redirected or rerouted by the stack to a different
+device than the selected TLS offload device. The stack will handle
+such condition using the :c:func:`sk_validate_xmit_skb` helper
+(TLS offload code installs :c:func:`tls_validate_xmit_skb` at this hook).
+Offload maintains information about all records until the data is
+fully acknowledged, so if skbs reach the wrong device they can be handled
+by software fallback.
+
+Any device TLS offload handling error on the transmission side must result
+in the packet being dropped. For example if a packet got out of order
+due to a bug in the stack or the device, reached the device and can't
+be encrypted such packet must be dropped.
+
+RX
+--
+
+If the device encounters any problems with TLS offload on the receive
+side it should pass the packet to the host's networking stack as it was
+received on the wire.
+
+For example authentication failure for any record in the segment should
+result in passing the unmodified packet to the software fallback. This means
+packets should not be modified "in place". Splitting segments to handle partial
+decryption is not advised. In other words either all records in the packet
+had been handled successfully and authenticated or the packet has to be passed
+to the host's stack as it was on the wire (recovering original packet in the
+driver if device provides precise error is sufficient).
+
+The Linux networking stack does not provide a way of reporting per-packet
+decryption and authentication errors, packets with errors must simply not
+have the :c:member:`decrypted` mark set.
+
+A packet should also not be handled by the TLS offload if it contains
+incorrect checksums.
+
+Performance metrics
+===================
+
+TLS offload can be characterized by the following basic metrics:
+
+ * max connection count
+ * connection installation rate
+ * connection installation latency
+ * total cryptographic performance
+
+Note that each TCP connection requires a TLS session in both directions,
+the performance may be reported treating each direction separately.
+
+Max connection count
+--------------------
+
+The number of connections device can support can be exposed via
+``devlink resource`` API.
+
+Total cryptographic performance
+-------------------------------
+
+Offload performance may depend on segment and record size.
+
+Overload of the cryptographic subsystem of the device should not have
+significant performance impact on non-offloaded streams.
+
+Statistics
+==========
+
+Following minimum set of TLS-related statistics should be reported
+by the driver:
+
+ * ``rx_tls_decrypted`` - number of successfully decrypted TLS segments
+ * ``tx_tls_encrypted`` - number of in-order TLS segments passed to device
+   for encryption
+ * ``tx_tls_ooo`` - number of TX packets which were part of a TLS stream
+   but did not arrive in the expected order
+ * ``tx_tls_drop_no_sync_data`` - number of TX packets dropped because
+   they arrived out of order and associated record could not be found
+   (see also :ref:`pre_tls_data`)
+
+Notable corner cases, exceptions and additional requirements
+============================================================
+
+.. _5tuple_problems:
+
+5-tuple matching limitations
+----------------------------
+
+The device can only recognize received packets based on the 5-tuple
+of the socket. Current ``ktls`` implementation will not offload sockets
+routed through software interfaces such as those used for tunneling
+or virtual networking. However, many packet transformations performed
+by the networking stack (most notably any BPF logic) do not require
+any intermediate software device, therefore a 5-tuple match may
+consistently miss at the device level. In such cases the device
+should still be able to perform TX offload (encryption) and should
+fallback cleanly to software decryption (RX).
+
+Out of order
+------------
+
+Introducing extra processing in NICs should not cause packets to be
+transmitted or received out of order, for example pure ACK packets
+should not be reordered with respect to data segments.
+
+Ingress reorder
+---------------
+
+A device is permitted to perform packet reordering for consecutive
+TCP segments (i.e. placing packets in the correct order) but any form
+of additional buffering is disallowed.
+
+Coexistence with standard networking offload features
+-----------------------------------------------------
+
+Offloaded ``ktls`` sockets should support standard TCP stack features
+transparently. Enabling device TLS offload should not cause any difference
+in packets as seen on the wire.
+
+Transport layer transparency
+----------------------------
+
+The device should not modify any packet headers for the purpose
+of the simplifying TLS offload.
+
+The device should not depend on any packet headers beyond what is strictly
+necessary for TLS offload.
+
+Segment drops
+-------------
+
+Dropping packets is acceptable only in the event of catastrophic
+system errors and should never be used as an error handling mechanism
+in cases arising from normal operation. In other words, reliance
+on TCP retransmissions to handle corner cases is not acceptable.
+
+TLS device features
+-------------------
+
+Drivers should ignore the changes to TLS the device feature flags.
+These flags will be acted upon accordingly by the core ``ktls`` code.
+TLS device feature flags only control adding of new TLS connection
+offloads, old connections will remain active after flags are cleared.
+
+Known bugs
+==========
+
+skb_orphan() leaks clear text
+-----------------------------
+
+Currently drivers depend on the :c:member:`sk` member of
+:c:type:`struct sk_buff <sk_buff>` to identify segments requiring
+encryption. Any operation which removes or does not preserve the socket
+association such as :c:func:`skb_orphan` or :c:func:`skb_clone`
+will cause the driver to miss the packets and lead to clear text leaks.
+
+Redirects leak clear text
+-------------------------
+
+In the RX direction, if segment has already been decrypted by the device
+and it gets redirected or mirrored - clear text will be transmitted out.
+
+.. _pre_tls_data:
+
+Transmission of pre-TLS data
+----------------------------
+
+User can enqueue some already encrypted and framed records before enabling
+``ktls`` on the socket. Those records have to get sent as they are. This is
+perfectly easy to handle in the software case - such data will be waiting
+in the TCP layer, TLS ULP won't see it. In the offloaded case when pre-queued
+segment reaches transmission point it appears to be out of order (before the
+expected TCP sequence number) and the stack does not have a record information
+associated.
+
+All segments without record information cannot, however, be assumed to be
+pre-queued data, because a race condition exists between TCP stack queuing
+a retransmission, the driver seeing the retransmission and TCP ACK arriving
+for the retransmitted data.

+Kernel TLS
+==========
+
+Overview
+========
+
+Transport Layer Security (TLS) is a Upper Layer Protocol (ULP) that runs over
+TCP. TLS provides end-to-end data integrity and confidentiality.
+
+User interface
+==============
+
+Creating a TLS connection
+-------------------------
+
+First create a new TCP socket and set the TLS ULP.
+
+.. code-block:: c
+
+  sock = socket(AF_INET, SOCK_STREAM, 0);
+  setsockopt(sock, SOL_TCP, TCP_ULP, "tls", sizeof("tls"));
+
+Setting the TLS ULP allows us to set/get TLS socket options. Currently
+only the symmetric encryption is handled in the kernel.  After the TLS
+handshake is complete, we have all the parameters required to move the
+data-path to the kernel. There is a separate socket option for moving
+the transmit and the receive into the kernel.
+
+.. code-block:: c
+
+  /* From linux/tls.h */
+  struct tls_crypto_info {
+          unsigned short version;
+          unsigned short cipher_type;
+  };
+
+  struct tls12_crypto_info_aes_gcm_128 {
+          struct tls_crypto_info info;
+          unsigned char iv[TLS_CIPHER_AES_GCM_128_IV_SIZE];
+          unsigned char key[TLS_CIPHER_AES_GCM_128_KEY_SIZE];
+          unsigned char salt[TLS_CIPHER_AES_GCM_128_SALT_SIZE];
+          unsigned char rec_seq[TLS_CIPHER_AES_GCM_128_REC_SEQ_SIZE];
+  };
+
+
+  struct tls12_crypto_info_aes_gcm_128 crypto_info;
+
+  crypto_info.info.version = TLS_1_2_VERSION;
+  crypto_info.info.cipher_type = TLS_CIPHER_AES_GCM_128;
+  memcpy(crypto_info.iv, iv_write, TLS_CIPHER_AES_GCM_128_IV_SIZE);
+  memcpy(crypto_info.rec_seq, seq_number_write,
+					TLS_CIPHER_AES_GCM_128_REC_SEQ_SIZE);
+  memcpy(crypto_info.key, cipher_key_write, TLS_CIPHER_AES_GCM_128_KEY_SIZE);
+  memcpy(crypto_info.salt, implicit_iv_write, TLS_CIPHER_AES_GCM_128_SALT_SIZE);
+
+  setsockopt(sock, SOL_TLS, TLS_TX, &crypto_info, sizeof(crypto_info));
+
+Transmit and receive are set separately, but the setup is the same, using either
+TLS_TX or TLS_RX.
+
+Sending TLS application data
+----------------------------
+
+After setting the TLS_TX socket option all application data sent over this
+socket is encrypted using TLS and the parameters provided in the socket option.
+For example, we can send an encrypted hello world record as follows:
+
+.. code-block:: c
+
+  const char *msg = "hello world\n";
+  send(sock, msg, strlen(msg));
+
+send() data is directly encrypted from the userspace buffer provided
+to the encrypted kernel send buffer if possible.
+
+The sendfile system call will send the file's data over TLS records of maximum
+length (2^14).
+
+.. code-block:: c
+
+  file = open(filename, O_RDONLY);
+  fstat(file, &stat);
+  sendfile(sock, file, &offset, stat.st_size);
+
+TLS records are created and sent after each send() call, unless
+MSG_MORE is passed.  MSG_MORE will delay creation of a record until
+MSG_MORE is not passed, or the maximum record size is reached.
+
+The kernel will need to allocate a buffer for the encrypted data.
+This buffer is allocated at the time send() is called, such that
+either the entire send() call will return -ENOMEM (or block waiting
+for memory), or the encryption will always succeed.  If send() returns
+-ENOMEM and some data was left on the socket buffer from a previous
+call using MSG_MORE, the MSG_MORE data is left on the socket buffer.
+
+Receiving TLS application data
+------------------------------
+
+After setting the TLS_RX socket option, all recv family socket calls
+are decrypted using TLS parameters provided.  A full TLS record must
+be received before decryption can happen.
+
+.. code-block:: c
+
+  char buffer[16384];
+  recv(sock, buffer, 16384);
+
+Received data is decrypted directly in to the user buffer if it is
+large enough, and no additional allocations occur.  If the userspace
+buffer is too small, data is decrypted in the kernel and copied to
+userspace.
+
+``EINVAL`` is returned if the TLS version in the received message does not
+match the version passed in setsockopt.
+
+``EMSGSIZE`` is returned if the received message is too big.
+
+``EBADMSG`` is returned if decryption failed for any other reason.
+
+Send TLS control messages
+-------------------------
+
+Other than application data, TLS has control messages such as alert
+messages (record type 21) and handshake messages (record type 22), etc.
+These messages can be sent over the socket by providing the TLS record type
+via a CMSG. For example the following function sends @data of @length bytes
+using a record of type @record_type.
+
+.. code-block:: c
+
+  /* send TLS control message using record_type */
+  static int klts_send_ctrl_message(int sock, unsigned char record_type,
+                                    void *data, size_t length)
+  {
+        struct msghdr msg = {0};
+        int cmsg_len = sizeof(record_type);
+        struct cmsghdr *cmsg;
+        char buf[CMSG_SPACE(cmsg_len)];
+        struct iovec msg_iov;   /* Vector of data to send/receive into.  */
+
+        msg.msg_control = buf;
+        msg.msg_controllen = sizeof(buf);
+        cmsg = CMSG_FIRSTHDR(&msg);
+        cmsg->cmsg_level = SOL_TLS;
+        cmsg->cmsg_type = TLS_SET_RECORD_TYPE;
+        cmsg->cmsg_len = CMSG_LEN(cmsg_len);
+        *CMSG_DATA(cmsg) = record_type;
+        msg.msg_controllen = cmsg->cmsg_len;
+
+        msg_iov.iov_base = data;
+        msg_iov.iov_len = length;
+        msg.msg_iov = &msg_iov;
+        msg.msg_iovlen = 1;
+
+        return sendmsg(sock, &msg, 0);
+  }
+
+Control message data should be provided unencrypted, and will be
+encrypted by the kernel.
+
+Receiving TLS control messages
+------------------------------
+
+TLS control messages are passed in the userspace buffer, with message
+type passed via cmsg.  If no cmsg buffer is provided, an error is
+returned if a control message is received.  Data messages may be
+received without a cmsg buffer set.
+
+.. code-block:: c
+
+  char buffer[16384];
+  char cmsg[CMSG_SPACE(sizeof(unsigned char))];
+  struct msghdr msg = {0};
+  msg.msg_control = cmsg;
+  msg.msg_controllen = sizeof(cmsg);
+
+  struct iovec msg_iov;
+  msg_iov.iov_base = buffer;
+  msg_iov.iov_len = 16384;
+
+  msg.msg_iov = &msg_iov;
+  msg.msg_iovlen = 1;
+
+  int ret = recvmsg(sock, &msg, 0 /* flags */);
+
+  struct cmsghdr *cmsg = CMSG_FIRSTHDR(&msg);
+  if (cmsg->cmsg_level == SOL_TLS &&
+      cmsg->cmsg_type == TLS_GET_RECORD_TYPE) {
+      int record_type = *((unsigned char *)CMSG_DATA(cmsg));
+      // Do something with record_type, and control message data in
+      // buffer.
+      //
+      // Note that record_type may be == to application data (23).
+  } else {
+      // Buffer contains application data.
+  }
+
+recv will never return data from mixed types of TLS records.
+
+Integrating in to userspace TLS library
+---------------------------------------
+
+At a high level, the kernel TLS ULP is a replacement for the record
+layer of a userspace TLS library.
+
+A patchset to OpenSSL to use ktls as the record layer is
+`here <https://github.com/Mellanox/openssl/commits/tls_rx2>`_.
+
+`An example <https://github.com/ktls/af_ktls-tool/commits/RX>`_
+of calling send directly after a handshake using gnutls.
+Since it doesn't implement a full record layer, control
+messages are not supported.

-  setsockopt(sock, SOL_TLS, TLS_TX, &crypto_info, sizeof(crypto_info));
-
-Transmit and receive are set separately, but the setup is the same, using either
-TLS_TX or TLS_RX.
-
-Sending TLS application data
-----------------------------
-
-After setting the TLS_TX socket option all application data sent over this
-socket is encrypted using TLS and the parameters provided in the socket option.
-For example, we can send an encrypted hello world record as follows:
-
-  const char *msg = "hello world\n";
-  send(sock, msg, strlen(msg));
-
-send() data is directly encrypted from the userspace buffer provided
-to the encrypted kernel send buffer if possible.
-
-The sendfile system call will send the file's data over TLS records of maximum
-length (2^14).
-
-  file = open(filename, O_RDONLY);
-  fstat(file, &stat);
-  sendfile(sock, file, &offset, stat.st_size);
-
-TLS records are created and sent after each send() call, unless
-MSG_MORE is passed.  MSG_MORE will delay creation of a record until
-MSG_MORE is not passed, or the maximum record size is reached.
-
-The kernel will need to allocate a buffer for the encrypted data.
-This buffer is allocated at the time send() is called, such that
-either the entire send() call will return -ENOMEM (or block waiting
-for memory), or the encryption will always succeed.  If send() returns
--ENOMEM and some data was left on the socket buffer from a previous
-call using MSG_MORE, the MSG_MORE data is left on the socket buffer.
-
-Receiving TLS application data
-------------------------------
-
-After setting the TLS_RX socket option, all recv family socket calls
-are decrypted using TLS parameters provided.  A full TLS record must
-be received before decryption can happen.
-
-  char buffer[16384];
-  recv(sock, buffer, 16384);
-
-Received data is decrypted directly in to the user buffer if it is
-large enough, and no additional allocations occur.  If the userspace
-buffer is too small, data is decrypted in the kernel and copied to
-userspace.
-
-EINVAL is returned if the TLS version in the received message does not
-match the version passed in setsockopt.
-
-EMSGSIZE is returned if the received message is too big.
-
-EBADMSG is returned if decryption failed for any other reason.
-
-Send TLS control messages
--------------------------
-
-Other than application data, TLS has control messages such as alert
-messages (record type 21) and handshake messages (record type 22), etc.
-These messages can be sent over the socket by providing the TLS record type
-via a CMSG. For example the following function sends @data of @length bytes
-using a record of type @record_type.
-
-/* send TLS control message using record_type */
-  static int klts_send_ctrl_message(int sock, unsigned char record_type,
-                                  void *data, size_t length)
-  {
-        struct msghdr msg = {0};
-        int cmsg_len = sizeof(record_type);
-        struct cmsghdr *cmsg;
-        char buf[CMSG_SPACE(cmsg_len)];
-        struct iovec msg_iov;   /* Vector of data to send/receive into.  */
-
-        msg.msg_control = buf;
-        msg.msg_controllen = sizeof(buf);
-        cmsg = CMSG_FIRSTHDR(&msg);
-        cmsg->cmsg_level = SOL_TLS;
-        cmsg->cmsg_type = TLS_SET_RECORD_TYPE;
-        cmsg->cmsg_len = CMSG_LEN(cmsg_len);
-        *CMSG_DATA(cmsg) = record_type;
-        msg.msg_controllen = cmsg->cmsg_len;
-
-        msg_iov.iov_base = data;
-        msg_iov.iov_len = length;
-        msg.msg_iov = &msg_iov;
-        msg.msg_iovlen = 1;
-
-        return sendmsg(sock, &msg, 0);
-  }
-
-Control message data should be provided unencrypted, and will be
-encrypted by the kernel.
-
-Receiving TLS control messages
-------------------------------
-
-TLS control messages are passed in the userspace buffer, with message
-type passed via cmsg.  If no cmsg buffer is provided, an error is
-returned if a control message is received.  Data messages may be
-received without a cmsg buffer set.
-
-  char buffer[16384];
-  char cmsg[CMSG_SPACE(sizeof(unsigned char))];
-  struct msghdr msg = {0};
-  msg.msg_control = cmsg;
-  msg.msg_controllen = sizeof(cmsg);
-
-  struct iovec msg_iov;
-  msg_iov.iov_base = buffer;
-  msg_iov.iov_len = 16384;
-
-  msg.msg_iov = &msg_iov;
-  msg.msg_iovlen = 1;
-
-  int ret = recvmsg(sock, &msg, 0 /* flags */);
-
-  struct cmsghdr *cmsg = CMSG_FIRSTHDR(&msg);
-  if (cmsg->cmsg_level == SOL_TLS &&
-      cmsg->cmsg_type == TLS_GET_RECORD_TYPE) {
-      int record_type = *((unsigned char *)CMSG_DATA(cmsg));
-      // Do something with record_type, and control message data in
-      // buffer.
-      //
-      // Note that record_type may be == to application data (23).
-  } else {
-      // Buffer contains application data.
-  }
-
-recv will never return data from mixed types of TLS records.
-
-Integrating in to userspace TLS library
----------------------------------------
-
-At a high level, the kernel TLS ULP is a replacement for the record
-layer of a userspace TLS library.
-
-A patchset to OpenSSL to use ktls as the record layer is here:
-
-https://github.com/Mellanox/openssl/commits/tls_rx2
-
-An example of calling send directly after a handshake using
-gnutls.  Since it doesn't implement a full record layer, control
-messages are not supported:

+================================================
+Generic bitfield packing and unpacking functions
+================================================
+
+Problem statement
+-----------------
+
+When working with hardware, one has to choose between several approaches of
+interfacing with it.
+One can memory-map a pointer to a carefully crafted struct over the hardware
+device's memory region, and access its fields as struct members (potentially
+declared as bitfields). But writing code this way would make it less portable,
+due to potential endianness mismatches between the CPU and the hardware device.
+Additionally, one has to pay close attention when translating register
+definitions from the hardware documentation into bit field indices for the
+structs. Also, some hardware (typically networking equipment) tends to group
+its register fields in ways that violate any reasonable word boundaries
+(sometimes even 64 bit ones). This creates the inconvenience of having to
+define "high" and "low" portions of register fields within the struct.
+A more robust alternative to struct field definitions would be to extract the
+required fields by shifting the appropriate number of bits. But this would
+still not protect from endianness mismatches, except if all memory accesses
+were performed byte-by-byte. Also the code can easily get cluttered, and the
+high-level idea might get lost among the many bit shifts required.
+Many drivers take the bit-shifting approach and then attempt to reduce the
+clutter with tailored macros, but more often than not these macros take
+shortcuts that still prevent the code from being truly portable.
+
+The solution
+------------
+
+This API deals with 2 basic operations:
+  - Packing a CPU-usable number into a memory buffer (with hardware
+    constraints/quirks)
+  - Unpacking a memory buffer (which has hardware constraints/quirks)
+    into a CPU-usable number.
+
+The API offers an abstraction over said hardware constraints and quirks,
+over CPU endianness and therefore between possible mismatches between
+the two.
+
+The basic unit of these API functions is the u64. From the CPU's
+perspective, bit 63 always means bit offset 7 of byte 7, albeit only
+logically. The question is: where do we lay this bit out in memory?
+
+The following examples cover the memory layout of a packed u64 field.
+The byte offsets in the packed buffer are always implicitly 0, 1, ... 7.
+What the examples show is where the logical bytes and bits sit.
+
+1. Normally (no quirks), we would do it like this:
+
+63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32
+7                       6                       5                        4
+31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10  9  8  7  6  5  4  3  2  1  0
+3                       2                       1                        0
+
+That is, the MSByte (7) of the CPU-usable u64 sits at memory offset 0, and the
+LSByte (0) of the u64 sits at memory offset 7.
+This corresponds to what most folks would regard to as "big endian", where
+bit i corresponds to the number 2^i. This is also referred to in the code
+comments as "logical" notation.
+
+
+2. If QUIRK_MSB_ON_THE_RIGHT is set, we do it like this:
+
+56 57 58 59 60 61 62 63 48 49 50 51 52 53 54 55 40 41 42 43 44 45 46 47 32 33 34 35 36 37 38 39
+7                       6                        5                       4
+24 25 26 27 28 29 30 31 16 17 18 19 20 21 22 23  8  9 10 11 12 13 14 15  0  1  2  3  4  5  6  7
+3                       2                        1                       0
+
+That is, QUIRK_MSB_ON_THE_RIGHT does not affect byte positioning, but
+inverts bit offsets inside a byte.
+
+
+3. If QUIRK_LITTLE_ENDIAN is set, we do it like this:
+
+39 38 37 36 35 34 33 32 47 46 45 44 43 42 41 40 55 54 53 52 51 50 49 48 63 62 61 60 59 58 57 56
+4                       5                       6                       7
+7  6  5  4  3  2  1  0  15 14 13 12 11 10  9  8 23 22 21 20 19 18 17 16 31 30 29 28 27 26 25 24
+0                       1                       2                       3
+
+Therefore, QUIRK_LITTLE_ENDIAN means that inside the memory region, every
+byte from each 4-byte word is placed at its mirrored position compared to
+the boundary of that word.
+
+4. If QUIRK_MSB_ON_THE_RIGHT and QUIRK_LITTLE_ENDIAN are both set, we do it
+   like this:
+
+32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63
+4                       5                       6                       7
+0  1  2  3  4  5  6  7  8   9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
+0                       1                       2                       3
+
+
+5. If just QUIRK_LSW32_IS_FIRST is set, we do it like this:
+
+31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10  9  8  7  6  5  4  3  2  1  0
+3                       2                       1                        0
+63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32
+7                       6                       5                        4
+
+In this case the 8 byte memory region is interpreted as follows: first
+4 bytes correspond to the least significant 4-byte word, next 4 bytes to
+the more significant 4-byte word.
+
+
+6. If QUIRK_LSW32_IS_FIRST and QUIRK_MSB_ON_THE_RIGHT are set, we do it like
+   this:
+
+24 25 26 27 28 29 30 31 16 17 18 19 20 21 22 23  8  9 10 11 12 13 14 15  0  1  2  3  4  5  6  7
+3                       2                        1                       0
+56 57 58 59 60 61 62 63 48 49 50 51 52 53 54 55 40 41 42 43 44 45 46 47 32 33 34 35 36 37 38 39
+7                       6                        5                       4
+
+
+7. If QUIRK_LSW32_IS_FIRST and QUIRK_LITTLE_ENDIAN are set, it looks like
+   this:
+
+7  6  5  4  3  2  1  0  15 14 13 12 11 10  9  8 23 22 21 20 19 18 17 16 31 30 29 28 27 26 25 24
+0                       1                       2                       3
+39 38 37 36 35 34 33 32 47 46 45 44 43 42 41 40 55 54 53 52 51 50 49 48 63 62 61 60 59 58 57 56
+4                       5                       6                       7
+
+
+8. If QUIRK_LSW32_IS_FIRST, QUIRK_LITTLE_ENDIAN and QUIRK_MSB_ON_THE_RIGHT
+   are set, it looks like this:
+
+0  1  2  3  4  5  6  7  8   9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
+0                       1                       2                       3
+32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63
+4                       5                       6                       7
+
+
+We always think of our offsets as if there were no quirk, and we translate
+them afterwards, before accessing the memory region.
+
+Intended use
+------------
+
+Drivers that opt to use this API first need to identify which of the above 3
+quirk combinations (for a total of 8) match what the hardware documentation
+describes. Then they should wrap the packing() function, creating a new
+xxx_packing() that calls it using the proper QUIRK_* one-hot bits set.
+
+The packing() function returns an int-encoded error code, which protects the
+programmer against incorrect API use.  The errors are not expected to occur
+durring runtime, therefore it is reasonable for xxx_packing() to return void
+and simply swallow those errors. Optionally it can dump stack or print the
+error description.

+Some users may not care about a bad user crashing their box
+(ie. single user/desktop systems) and really want the DAWR.  This
+allows them to force enable DAWR.
+
+This flag can also be used to disable DAWR access. Once this is
+cleared, all DAWR access should be cleared immediately and your
+machine once again safe from crashing.
+
+Userspace may get confused by toggling this. If DAWR is force
+enabled/disabled between getting the number of breakpoints (via
+PTRACE_GETHWDBGINFO) and setting the breakpoint, userspace will get an
+inconsistent view of what's available. Similarly for guests.
+
+For the DAWR to be enabled in a KVM guest, the DAWR needs to be force
+enabled in the host AND the guest. For this reason, this won't work on
+POWERVM as it doesn't allow the HCALL to work. Writes of 'Y' to the
+dawr_enable_dangerous file will fail if the hypervisor doesn't support
+writing the DAWR.
+
+To double check the DAWR is working, run this kernel selftest:
+  tools/testing/selftests/powerpc/ptrace/ptrace-hwbreak.c
+Any errors/failures/skips mean something is wrong.

 In short, rcu_dereference() is -not- optional when you are going to
 dereference the resulting pointer.
+
+
+WHICH MEMBER OF THE rcu_dereference() FAMILY SHOULD YOU USE?
+
+First, please avoid using rcu_dereference_raw() and also please avoid
+using rcu_dereference_check() and rcu_dereference_protected() with a
+second argument with a constant value of 1 (or true, for that matter).
+With that caution out of the way, here is some guidance for which
+member of the rcu_dereference() to use in various situations:
+
+1.	If the access needs to be within an RCU read-side critical
+	section, use rcu_dereference().  With the new consolidated
+	RCU flavors, an RCU read-side critical section is entered
+	using rcu_read_lock(), anything that disables bottom halves,
+	anything that disables interrupts, or anything that disables
+	preemption.
+
+2.	If the access might be within an RCU read-side critical section
+	on the one hand, or protected by (say) my_lock on the other,
+	use rcu_dereference_check(), for example:
+
+		p1 = rcu_dereference_check(p->rcu_protected_pointer,
+					   lockdep_is_held(&my_lock));
+
+
+3.	If the access might be within an RCU read-side critical section
+	on the one hand, or protected by either my_lock or your_lock on
+	the other, again use rcu_dereference_check(), for example:
+
+		p1 = rcu_dereference_check(p->rcu_protected_pointer,
+					   lockdep_is_held(&my_lock) ||
+					   lockdep_is_held(&your_lock));
+
+4.	If the access is on the update side, so that it is always protected
+	by my_lock, use rcu_dereference_protected():
+
+		p1 = rcu_dereference_protected(p->rcu_protected_pointer,
+					       lockdep_is_held(&my_lock));
+
+	This can be extended to handle multiple locks as in #3 above,
+	and both can be extended to check other conditions as well.
+
+5.	If the protection is supplied by the caller, and is thus unknown
+	to this code, that is the rare case when rcu_dereference_raw()
+	is appropriate.  In addition, rcu_dereference_raw() might be
+	appropriate when the lockdep expression would be excessively
+	complex, except that a better approach in that case might be to
+	take a long hard look at your synchronization design.  Still,
+	there are data-locking cases where any one of a very large number
+	of locks or reference counters suffices to protect the pointer,
+	so rcu_dereference_raw() does have its place.
+
+	However, its place is probably quite a bit smaller than one
+	might expect given the number of uses in the current kernel.
+	Ditto for its synonym, rcu_dereference_check( ... , 1), and
+	its close relative, rcu_dereference_protected(... , 1).
+
+
+SPARSE CHECKING OF RCU-PROTECTED POINTERS
+
+The sparse static-analysis tool checks for direct access to RCU-protected
+pointers, which can result in "interesting" bugs due to compiler
+optimizations involving invented loads and perhaps also load tearing.
+For example, suppose someone mistakenly does something like this:
+
+	p = q->rcu_protected_pointer;
+	do_something_with(p->a);
+	do_something_else_with(p->b);
+
+If register pressure is high, the compiler might optimize "p" out
+of existence, transforming the code to something like this:
+
+	do_something_with(q->rcu_protected_pointer->a);
+	do_something_else_with(q->rcu_protected_pointer->b);
+
+This could fatally disappoint your code if q->rcu_protected_pointer
+changed in the meantime.  Nor is this a theoretical problem:  Exactly
+this sort of bug cost Paul E. McKenney (and several of his innocent
+colleagues) a three-day weekend back in the early 1990s.
+
+Load tearing could of course result in dereferencing a mashup of a pair
+of pointers, which also might fatally disappoint your code.
+
+These problems could have been avoided simply by making the code instead
+read as follows:
+
+	p = rcu_dereference(q->rcu_protected_pointer);
+	do_something_with(p->a);
+	do_something_else_with(p->b);
+
+Unfortunately, these sorts of bugs can be extremely hard to spot during
+review.  This is where the sparse tool comes into play, along with the
+"__rcu" marker.  If you mark a pointer declaration, whether in a structure
+or as a formal parameter, with "__rcu", which tells sparse to complain if
+this pointer is accessed directly.  It will also cause sparse to complain
+if a pointer not marked with "__rcu" is accessed using rcu_dereference()
+and friends.  For example, ->rcu_protected_pointer might be declared as
+follows:
+
+	struct foo __rcu *rcu_protected_pointer;
+
+Use of "__rcu" is opt-in.  If you choose not to use it, then you should
+ignore the sparse warnings.

-			Low Level Serial API
-			--------------------
-
-
-This document is meant as a brief overview of some aspects of the new serial
-driver.  It is not complete, any questions you have should be directed to
-<rmk@arm.linux.org.uk>
-
-The reference implementation is contained within amba-pl011.c.
-
-
-
-Low Level Serial Hardware Driver
---------------------------------
-
-The low level serial hardware driver is responsible for supplying port
-information (defined by uart_port) and a set of control methods (defined
-by uart_ops) to the core serial driver.  The low level driver is also
-responsible for handling interrupts for the port, and providing any
-console support.
-
-
-Console Support
----------------
-
-The serial core provides a few helper functions.  This includes identifing
-the correct port structure (via uart_get_console) and decoding command line
-arguments (uart_parse_options).
-
-There is also a helper function (uart_console_write) which performs a
-character by character write, translating newlines to CRLF sequences.
-Driver writers are recommended to use this function rather than implementing
-their own version.
-
-
-Locking
--------
-
-It is the responsibility of the low level hardware driver to perform the
-necessary locking using port->lock.  There are some exceptions (which
-are described in the uart_ops listing below.)
-
-There are two locks.  A per-port spinlock, and an overall semaphore.
-
-From the core driver perspective, the port->lock locks the following
-data:
-
-	port->mctrl
-	port->icount
-	port->state->xmit.head (circ_buf->head)
-	port->state->xmit.tail (circ_buf->tail)
-
-The low level driver is free to use this lock to provide any additional
-locking.
-
-The port_sem semaphore is used to protect against ports being added/
-removed or reconfigured at inappropriate times. Since v2.6.27, this
-semaphore has been the 'mutex' member of the tty_port struct, and
-commonly referred to as the port mutex.
-
-
-uart_ops
---------
-
-The uart_ops structure is the main interface between serial_core and the
-hardware specific driver.  It contains all the methods to control the
-hardware.
-
-  tx_empty(port)
-	This function tests whether the transmitter fifo and shifter
-	for the port described by 'port' is empty.  If it is empty,
-	this function should return TIOCSER_TEMT, otherwise return 0.
-	If the port does not support this operation, then it should
-	return TIOCSER_TEMT.
-
-	Locking: none.
-	Interrupts: caller dependent.
-	This call must not sleep
-
-  set_mctrl(port, mctrl)
-	This function sets the modem control lines for port described
-	by 'port' to the state described by mctrl.  The relevant bits
-	of mctrl are:
-		- TIOCM_RTS	RTS signal.
-		- TIOCM_DTR	DTR signal.
-		- TIOCM_OUT1	OUT1 signal.
-		- TIOCM_OUT2	OUT2 signal.
-		- TIOCM_LOOP	Set the port into loopback mode.
-	If the appropriate bit is set, the signal should be driven
-	active.  If the bit is clear, the signal should be driven
-	inactive.
-
-	Locking: port->lock taken.
-	Interrupts: locally disabled.
-	This call must not sleep
-
-  get_mctrl(port)
-	Returns the current state of modem control inputs.  The state
-	of the outputs should not be returned, since the core keeps
-	track of their state.  The state information should include:
-		- TIOCM_CAR	state of DCD signal
-		- TIOCM_CTS	state of CTS signal
-		- TIOCM_DSR	state of DSR signal
-		- TIOCM_RI	state of RI signal
-	The bit is set if the signal is currently driven active.  If
-	the port does not support CTS, DCD or DSR, the driver should
-	indicate that the signal is permanently active.  If RI is
-	not available, the signal should not be indicated as active.
-
-	Locking: port->lock taken.
-	Interrupts: locally disabled.
-	This call must not sleep
-
-  stop_tx(port)
-	Stop transmitting characters.  This might be due to the CTS
-	line becoming inactive or the tty layer indicating we want
-	to stop transmission due to an XOFF character.
-
-	The driver should stop transmitting characters as soon as
-	possible.
-
-	Locking: port->lock taken.
-	Interrupts: locally disabled.
-	This call must not sleep
-
-  start_tx(port)
-	Start transmitting characters.
-
-	Locking: port->lock taken.
-	Interrupts: locally disabled.
-	This call must not sleep
-
-  throttle(port)
-	Notify the serial driver that input buffers for the line discipline are
-	close to full, and it should somehow signal that no more characters
-	should be sent to the serial port.
-	This will be called only if hardware assisted flow control is enabled.
-
-	Locking: serialized with .unthrottle() and termios modification by the
-		 tty layer.
-
-  unthrottle(port)
-	Notify the serial driver that characters can now be sent to the serial
-	port without fear of overrunning the input buffers of the line
-	disciplines.
-	This will be called only if hardware assisted flow control is enabled.
-
-	Locking: serialized with .throttle() and termios modification by the
-		 tty layer.
-
-  send_xchar(port,ch)
-	Transmit a high priority character, even if the port is stopped.
-	This is used to implement XON/XOFF flow control and tcflow().  If
-	the serial driver does not implement this function, the tty core
-	will append the character to the circular buffer and then call
-	start_tx() / stop_tx() to flush the data out.
-
-	Do not transmit if ch == '\0' (__DISABLED_CHAR).
-
-	Locking: none.
-	Interrupts: caller dependent.
-
-  stop_rx(port)
-	Stop receiving characters; the port is in the process of
-	being closed.
-
-	Locking: port->lock taken.
-	Interrupts: locally disabled.
-	This call must not sleep
-
-  enable_ms(port)
-	Enable the modem status interrupts.
-
-	This method may be called multiple times.  Modem status
-	interrupts should be disabled when the shutdown method is
-	called.
-
-	Locking: port->lock taken.
-	Interrupts: locally disabled.
-	This call must not sleep
-
-  break_ctl(port,ctl)
-	Control the transmission of a break signal.  If ctl is
-	nonzero, the break signal should be transmitted.  The signal
-	should be terminated when another call is made with a zero
-	ctl.
-
-	Locking: caller holds tty_port->mutex
-
-  startup(port)
-	Grab any interrupt resources and initialise any low level driver
-	state.  Enable the port for reception.  It should not activate
-	RTS nor DTR; this will be done via a separate call to set_mctrl.
-
-	This method will only be called when the port is initially opened.
-
-	Locking: port_sem taken.
-	Interrupts: globally disabled.
-
-  shutdown(port)
-	Disable the port, disable any break condition that may be in
-	effect, and free any interrupt resources.  It should not disable
-	RTS nor DTR; this will have already been done via a separate
-	call to set_mctrl.
-
-	Drivers must not access port->state once this call has completed.
-
-	This method will only be called when there are no more users of
-	this port.
-
-	Locking: port_sem taken.
-	Interrupts: caller dependent.
-
-  flush_buffer(port)
-	Flush any write buffers, reset any DMA state and stop any
-	ongoing DMA transfers.
-
-	This will be called whenever the port->state->xmit circular
-	buffer is cleared.
-
-	Locking: port->lock taken.
-	Interrupts: locally disabled.
-	This call must not sleep
-
-  set_termios(port,termios,oldtermios)
-	Change the port parameters, including word length, parity, stop
-	bits.  Update read_status_mask and ignore_status_mask to indicate
-	the types of events we are interested in receiving.  Relevant
-	termios->c_cflag bits are:
-		CSIZE	- word size
-		CSTOPB	- 2 stop bits
-		PARENB	- parity enable
-		PARODD	- odd parity (when PARENB is in force)
-		CREAD	- enable reception of characters (if not set,
-			  still receive characters from the port, but
-			  throw them away.
-		CRTSCTS	- if set, enable CTS status change reporting
-		CLOCAL	- if not set, enable modem status change
-			  reporting.
-	Relevant termios->c_iflag bits are:
-		INPCK	- enable frame and parity error events to be
-			  passed to the TTY layer.
-		BRKINT
-		PARMRK	- both of these enable break events to be
-			  passed to the TTY layer.
-
-		IGNPAR	- ignore parity and framing errors
-		IGNBRK	- ignore break errors,  If IGNPAR is also
-			  set, ignore overrun errors as well.
-	The interaction of the iflag bits is as follows (parity error
-	given as an example):
-	Parity error	INPCK	IGNPAR
-	n/a		0	n/a	character received, marked as
-					TTY_NORMAL
-	None		1	n/a	character received, marked as
-					TTY_NORMAL
-	Yes		1	0	character received, marked as
-					TTY_PARITY
-	Yes		1	1	character discarded
-
-	Other flags may be used (eg, xon/xoff characters) if your
-	hardware supports hardware "soft" flow control.
-
-	Locking: caller holds tty_port->mutex
-	Interrupts: caller dependent.
-	This call must not sleep
-
-  set_ldisc(port,termios)
-	Notifier for discipline change. See Documentation/serial/tty.txt.
-
-	Locking: caller holds tty_port->mutex
-
-  pm(port,state,oldstate)
-	Perform any power management related activities on the specified
-	port.  State indicates the new state (defined by
-	enum uart_pm_state), oldstate indicates the previous state.
-
-	This function should not be used to grab any resources.
-
-	This will be called when the port is initially opened and finally
-	closed, except when the port is also the system console.  This
-	will occur even if CONFIG_PM is not set.
-
-	Locking: none.
-	Interrupts: caller dependent.
-
-  type(port)
-	Return a pointer to a string constant describing the specified
-	port, or return NULL, in which case the string 'unknown' is
-	substituted.
-
-	Locking: none.
-	Interrupts: caller dependent.
-
-  release_port(port)
-	Release any memory and IO region resources currently in use by
-	the port.
-
-	Locking: none.
-	Interrupts: caller dependent.
-
-  request_port(port)
-	Request any memory and IO region resources required by the port.
-	If any fail, no resources should be registered when this function
-	returns, and it should return -EBUSY on failure.
-
-	Locking: none.
-	Interrupts: caller dependent.
-
-  config_port(port,type)
-	Perform any autoconfiguration steps required for the port.  `type`
-	contains a bit mask of the required configuration.  UART_CONFIG_TYPE
-	indicates that the port requires detection and identification.
-	port->type should be set to the type found, or PORT_UNKNOWN if
-	no port was detected.
-
-	UART_CONFIG_IRQ indicates autoconfiguration of the interrupt signal,
-	which should be probed using standard kernel autoprobing techniques.
-	This is not necessary on platforms where ports have interrupts
-	internally hard wired (eg, system on a chip implementations).
-
-	Locking: none.
-	Interrupts: caller dependent.
-
-  verify_port(port,serinfo)
-	Verify the new serial port information contained within serinfo is
-	suitable for this port type.
-
-	Locking: none.
-	Interrupts: caller dependent.
-
-  ioctl(port,cmd,arg)
-	Perform any port specific IOCTLs.  IOCTL commands must be defined
-	using the standard numbering system found in <asm/ioctl.h>
-
-	Locking: none.
-	Interrupts: caller dependent.
-
-  poll_init(port)
-	Called by kgdb to perform the minimal hardware initialization needed
-	to support poll_put_char() and poll_get_char().  Unlike ->startup()
-	this should not request interrupts.
-
-	Locking: tty_mutex and tty_port->mutex taken.
-	Interrupts: n/a.
-
-  poll_put_char(port,ch)
-	Called by kgdb to write a single character directly to the serial
-	port.  It can and should block until there is space in the TX FIFO.
-
-	Locking: none.
-	Interrupts: caller dependent.
-	This call must not sleep
-
-  poll_get_char(port)
-	Called by kgdb to read a single character directly from the serial
-	port.  If data is available, it should be returned; otherwise
-	the function should return NO_POLL_CHAR immediately.
-
-	Locking: none.
-	Interrupts: caller dependent.
-	This call must not sleep
-
-Other functions
----------------
-
-uart_update_timeout(port,cflag,baud)
-	Update the FIFO drain timeout, port->timeout, according to the
-	number of bits, parity, stop bits and baud rate.
-
-	Locking: caller is expected to take port->lock
-	Interrupts: n/a
-
-uart_get_baud_rate(port,termios,old,min,max)
-	Return the numeric baud rate for the specified termios, taking
-	account of the special 38400 baud "kludge".  The B0 baud rate
-	is mapped to 9600 baud.
-
-	If the baud rate is not within min..max, then if old is non-NULL,
-	the original baud rate will be tried.  If that exceeds the
-	min..max constraint, 9600 baud will be returned.  termios will
-	be updated to the baud rate in use.
-
-	Note: min..max must always allow 9600 baud to be selected.
-
-	Locking: caller dependent.
-	Interrupts: n/a
-
-uart_get_divisor(port,baud)
-	Return the divisor (baud_base / baud) for the specified baud
-	rate, appropriately rounded.
-
-	If 38400 baud and custom divisor is selected, return the
-	custom divisor instead.
-
-	Locking: caller dependent.
-	Interrupts: n/a
-
-uart_match_port(port1,port2)
-	This utility function can be used to determine whether two
-	uart_port structures describe the same port.
-
-	Locking: n/a
-	Interrupts: n/a
-
-uart_write_wakeup(port)
-	A driver is expected to call this function when the number of
-	characters in the transmit buffer have dropped below a threshold.
-
-	Locking: port->lock should be held.
-	Interrupts: n/a
-
-uart_register_driver(drv)
-	Register a uart driver with the core driver.  We in turn register
-	with the tty layer, and initialise the core driver per-port state.
-
-	drv->port should be NULL, and the per-port structures should be
-	registered using uart_add_one_port after this call has succeeded.
-
-	Locking: none
-	Interrupts: enabled
-
-uart_unregister_driver()
-	Remove all references to a driver from the core driver.  The low
-	level driver must have removed all its ports via the
-	uart_remove_one_port() if it registered them with uart_add_one_port().
-
-	Locking: none
-	Interrupts: enabled
-
-uart_suspend_port()
-
-uart_resume_port()
-
-uart_add_one_port()
-
-uart_remove_one_port()
-
-Other notes
------------
-
-It is intended some day to drop the 'unused' entries from uart_port, and
-allow low level drivers to register their own individual uart_port's with
-the core.  This will allow drivers to use uart_port as a pointer to a
-structure containing both the uart_port entry with their own extensions,
-thus:
-
-	struct my_port {
-		struct uart_port	port;
-		int			my_stuff;
-	};
-
-Modem control lines via GPIO
-----------------------------
-
-Some helpers are provided in order to set/get modem control lines via GPIO.
-
-mctrl_gpio_init(port, idx):
-	This will get the {cts,rts,...}-gpios from device tree if they are
-	present and request them, set direction etc, and return an
-	allocated structure. devm_* functions are used, so there's no need
-	to call mctrl_gpio_free().
-	As this sets up the irq handling make sure to not handle changes to the
-	gpio input lines in your driver, too.
-
-mctrl_gpio_free(dev, gpios):
-	This will free the requested gpios in mctrl_gpio_init().
-	As devm_* functions are used, there's generally no need to call
-	this function.
-
-mctrl_gpio_to_gpiod(gpios, gidx)
-	This returns the gpio_desc structure associated to the modem line
-	index.
-
-mctrl_gpio_set(gpios, mctrl):
-	This will sets the gpios according to the mctrl state.
-
-mctrl_gpio_get(gpios, mctrl):
-	This will update mctrl with the gpios values.
-
-mctrl_gpio_enable_ms(gpios):
-	Enables irqs and handling of changes to the ms lines.
-
-mctrl_gpio_disable_ms(gpios):
-	Disables irqs and handling of changes to the ms lines.

+			- if not set, enable modem status change
+			  reporting.
+
+	Relevant termios->c_iflag bits are:
+
+		INPCK
+			- enable frame and parity error events to be
+			  passed to the TTY layer.
+		BRKINT / PARMRK
+			- both of these enable break events to be
+			  passed to the TTY layer.
+
+		IGNPAR
+			- ignore parity and framing errors
+		IGNBRK
+			- ignore break errors,  If IGNPAR is also
+			  set, ignore overrun errors as well.
+
+	The interaction of the iflag bits is as follows (parity error
+	given as an example):
+
+	=============== ======= ======  =============================
+	Parity error	INPCK	IGNPAR
+	=============== ======= ======  =============================
+	n/a		0	n/a	character received, marked as
+					TTY_NORMAL

+					TTY_PARITY
+	Yes		1	1	character discarded
+	=============== ======= ======  =============================

+
+	Locking: none
+
+	Interrupts: enabled
+
+uart_unregister_driver()
+	Remove all references to a driver from the core driver.  The low
+	level driver must have removed all its ports via the
+	uart_remove_one_port() if it registered them with uart_add_one_port().
+
+	Locking: none
+
+	Interrupts: enabled
+
+**uart_suspend_port()**
+
+**uart_resume_port()**
+
+**uart_add_one_port()**
+
+**uart_remove_one_port()**
+
+Other notes
+-----------
+
+It is intended some day to drop the 'unused' entries from uart_port, and
+allow low level drivers to register their own individual uart_port's with
+the core.  This will allow drivers to use uart_port as a pointer to a
+structure containing both the uart_port entry with their own extensions,
+thus::
+
+	struct my_port {
+		struct uart_port	port;
+		int			my_stuff;
+	};
+
+Modem control lines via GPIO
+----------------------------
+
+Some helpers are provided in order to set/get modem control lines via GPIO.
+
+mctrl_gpio_init(port, idx):
+	This will get the {cts,rts,...}-gpios from device tree if they are
+	present and request them, set direction etc, and return an
+	allocated structure. `devm_*` functions are used, so there's no need
+	to call mctrl_gpio_free().
+	As this sets up the irq handling make sure to not handle changes to the
+	gpio input lines in your driver, too.
+
+mctrl_gpio_free(dev, gpios):
+	This will free the requested gpios in mctrl_gpio_init().
+	As `devm_*` functions are used, there's generally no need to call
+	this function.
+
+mctrl_gpio_to_gpiod(gpios, gidx)
+	This returns the gpio_desc structure associated to the modem line
+	index.
+
+mctrl_gpio_set(gpios, mctrl):
+	This will sets the gpios according to the mctrl state.
+
+mctrl_gpio_get(gpios, mctrl):
+	This will update mctrl with the gpios values.
+
+mctrl_gpio_enable_ms(gpios):
+	Enables irqs and handling of changes to the ms lines.
+
+mctrl_gpio_disable_ms(gpios):
+	Disables irqs and handling of changes to the ms lines.

-
-   This driver and installation procedure have been developed upon Linux Kernel
-   2.4.x and 2.6.x. This driver supports Intel x86 hardware platform. In order
-   to maintain compatibility, this version has also been properly tested with
-   RedHat, Mandrake, Fedora and S.u.S.E Linux. However, if compatibility problem
-   occurs, please contact Moxa at support@moxa.com.tw.
-
-   In addition to device driver, useful utilities are also provided in this
-   version. They are
-    - msdiag     Diagnostic program for displaying installed Moxa
-                 Smartio/Industio boards.
-    - msmon      Monitor program to observe data count and line status signals.
-    - msterm     A simple terminal program which is useful in testing serial
-	         ports.
-    - io-irq.exe Configuration program to setup ISA boards. Please note that
-                 this program can only be executed under DOS.
-
-   All the drivers and utilities are published in form of source code under
-   GNU General Public License in this version. Please refer to GNU General
-   Public License announcement in each source code file for more detail.
-
-   In Moxa's Web sites, you may always find latest driver at http://www.moxa.com/.
-
-   This version of driver can be installed as Loadable Module (Module driver)
-   or built-in into kernel (Static driver). You may refer to following
-   installation procedure for suitable one. Before you install the driver,
-   please refer to hardware installation procedure in the User's Manual.
-
-   We assume the user should be familiar with following documents.
-   - Serial-HOWTO
-   - Kernel-HOWTO
-
------------------------------------------------------------------------------
-2. System Requirement
-   - Hardware platform: Intel x86 machine
-   - Kernel version: 2.4.x or 2.6.x
-   - gcc version 2.72 or later
-   - Maximum 4 boards can be installed in combination
-
------------------------------------------------------------------------------
-3. Installation
-
-   3.1 Hardware installation
-   3.2 Driver files
-   3.3 Device naming convention
-   3.4 Module driver configuration
-   3.5 Static driver configuration for Linux kernel 2.4.x, 2.6.x.
-   3.6 Custom configuration
-   3.7 Verify driver installation
-
-
-   3.1 Hardware installation
-
-       There are two types of buses, ISA and PCI, for Smartio/Industio
-       family multiport board.
-
-       ISA board
-       ---------
-       You'll have to configure CAP address, I/O address, Interrupt Vector
-       as well as IRQ before installing this driver. Please refer to hardware
-       installation procedure in User's Manual before proceed any further.
-       Please make sure the JP1 is open after the ISA board is set properly.
-
-       PCI/UPCI board
-       --------------
-       You may need to adjust IRQ usage in BIOS to avoid from IRQ conflict
-       with other ISA devices. Please refer to hardware installation
-       procedure in User's Manual in advance.
-
-       PCI IRQ Sharing
-       -----------
-       Each port within the same multiport board shares the same IRQ. Up to
-       4 Moxa Smartio/Industio PCI Family multiport boards can be installed
-       together on one system and they can share the same IRQ.
-
-
-   3.2 Driver files
-
-       The driver file may be obtained from ftp, CD-ROM or floppy disk. The
-       first step, anyway, is to copy driver file "mxser.tgz" into specified
-       directory. e.g. /moxa. The execute commands as below.
-
-       # cd /
-       # mkdir moxa
-       # cd /moxa
-       # tar xvf /dev/fd0
-
-       or
-
-       # cd /
-       # mkdir moxa
-       # cd /moxa
-       # cp /mnt/cdrom/<driver directory>/mxser.tgz .
-       # tar xvfz mxser.tgz
-
-
-   3.3 Device naming convention
-
-       You may find all the driver and utilities files in /moxa/mxser.
-       Following installation procedure depends on the model you'd like to
-       run the driver. If you prefer module driver, please refer to 3.4.
-       If static driver is required, please refer to 3.5.
-
-       Dialin and callout port
-       -----------------------
-       This driver remains traditional serial device properties. There are
-       two special file name for each serial port. One is dial-in port
-       which is named "ttyMxx". For callout port, the naming convention
-       is "cumxx".
-
-       Device naming when more than 2 boards installed
-       -----------------------------------------------
-       Naming convention for each Smartio/Industio multiport board is
-       pre-defined as below.
-
-       Board Num.	 Dial-in Port	      Callout port
-       1st board	ttyM0  - ttyM7	      cum0  - cum7
-       2nd board	ttyM8  - ttyM15       cum8  - cum15
-       3rd board	ttyM16 - ttyM23       cum16 - cum23
-       4th board	ttyM24 - ttym31       cum24 - cum31
-
-
-       !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-       Under Kernel 2.6 the cum Device is Obsolete. So use ttyM*
-       device instead.
-       !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-       Board sequence
-       --------------
-       This driver will activate ISA boards according to the parameter set
-       in the driver. After all specified ISA board activated, PCI board
-       will be installed in the system automatically driven.
-       Therefore the board number is sorted by the CAP address of ISA boards.
-       For PCI boards, their sequence will be after ISA boards and C168H/PCI
-       has higher priority than C104H/PCI boards.
-
-   3.4 Module driver configuration
-       Module driver is easiest way to install. If you prefer static driver
-       installation, please skip this paragraph.
-
-
-       ------------- Prepare to use the MOXA driver--------------------
-       3.4.1 Create tty device with correct major number
-          Before using MOXA driver, your system must have the tty devices
-          which are created with driver's major number. We offer one shell
-          script "msmknod" to simplify the procedure.
-          This step is only needed to be executed once. But you still
-          need to do this procedure when:
-          a. You change the driver's major number. Please refer the "3.7"
-             section.
-          b. Your total installed MOXA boards number is changed. Maybe you
-             add/delete one MOXA board.
-          c. You want to change the tty name. This needs to modify the
-             shell script "msmknod"
-
-          The procedure is:
-	  # cd /moxa/mxser/driver
-	  # ./msmknod
-
-          This shell script will require the major number for dial-in
-          device and callout device to create tty device. You also need
-          to specify the total installed MOXA board number. Default major
-          numbers for dial-in device and callout device are 30, 35. If
-          you need to change to other number, please refer section "3.7"
-          for more detailed procedure.
-          Msmknod will delete any special files occupying the same device
-          naming.
-
-       3.4.2 Build the MOXA driver and utilities
-          Before using the MOXA driver and utilities, you need compile the
-          all the source code. This step is only need to be executed once.
-          But you still re-compile the source code if you modify the source
-          code. For example, if you change the driver's major number (see
-          "3.7" section), then you need to do this step again.
-
-          Find "Makefile" in /moxa/mxser, then run
-
-	  # make clean; make install
-
-          !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
-	  For Red Hat 9, Red Hat Enterprise Linux AS3/ES3/WS3 & Fedora Core1:
-	  # make clean; make installsp1
-
-	  For Red Hat Enterprise Linux AS4/ES4/WS4:
-	  # make clean; make installsp2
-          !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!
-
-	  The driver files "mxser.o" and utilities will be properly compiled
-	  and copied to system directories respectively.
-
-       ------------- Load MOXA driver--------------------
-       3.4.3 Load the MOXA driver
-
-	  # modprobe mxser <argument>
-
-	  will activate the module driver. You may run "lsmod" to check
-	  if "mxser" is activated. If the MOXA board is ISA board, the
-          <argument> is needed. Please refer to section "3.4.5" for more
-          information.
-
-
-       ------------- Load MOXA driver on boot --------------------
-       3.4.4 For the above description, you may manually execute
-          "modprobe mxser" to activate this driver and run
-	  "rmmod mxser" to remove it.
-          However, it's better to have a boot time configuration to
-          eliminate manual operation. Boot time configuration can be
-          achieved by rc file. We offer one "rc.mxser" file to simplify
-          the procedure under "moxa/mxser/driver".
-
-          But if you use ISA board, please modify the "modprobe ..." command
-          to add the argument (see "3.4.5" section). After modifying the
-          rc.mxser, please try to execute "/moxa/mxser/driver/rc.mxser"
-          manually to make sure the modification is ok. If any error
-          encountered, please try to modify again. If the modification is
-          completed, follow the below step.
-
-	  Run following command for setting rc files.
-
-	  # cd /moxa/mxser/driver
-	  # cp ./rc.mxser /etc/rc.d
-	  # cd /etc/rc.d
-
-	  Check "rc.serial" is existed or not. If "rc.serial" doesn't exist,
-	  create it by vi, run "chmod 755 rc.serial" to change the permission.
-	  Add "/etc/rc.d/rc.mxser" in last line,
-
-          Reboot and check if moxa.o activated by "lsmod" command.
-
-       3.4.5. If you'd like to drive Smartio/Industio ISA boards in the system,
-          you'll have to add parameter to specify CAP address of given
-	  board while activating "mxser.o". The format for parameters are
-	  as follows.
-
-	  modprobe mxser ioaddr=0x???,0x???,0x???,0x???
-				|      |     |	  |
-				|      |     |	  +- 4th ISA board
-				|      |     +------ 3rd ISA board
-				|      +------------ 2nd ISA board
-				+------------------- 1st ISA board
-
-   3.5 Static driver configuration for Linux kernel 2.4.x and 2.6.x
-
-       Note: To use static driver, you must install the linux kernel
-             source package.
-
-       3.5.1 Backup the built-in driver in the kernel.
-          # cd /usr/src/linux/drivers/char
-          # mv mxser.c mxser.c.old
-
-          For Red Hat 7.x user, you need to create link:
-          # cd /usr/src
-          # ln -s linux-2.4 linux
-
-       3.5.2 Create link
-	  # cd /usr/src/linux/drivers/char
-	  # ln -s /moxa/mxser/driver/mxser.c mxser.c
-
-       3.5.3 Add CAP address list for ISA boards. For PCI boards user,
-          please skip this step.
-
-	  In module mode, the CAP address for ISA board is given by
-	  parameter. In static driver configuration, you'll have to
-	  assign it within driver's source code. If you will not
-	  install any ISA boards, you may skip to next portion.
-	  The instructions to modify driver source code are as
-	  below.
-	  a. # cd /moxa/mxser/driver
-	     # vi mxser.c
-	  b. Find the array mxserBoardCAP[] as below.
-
-	     static int mxserBoardCAP[]
-	     = {0x00, 0x00, 0x00, 0x00};
-
-	  c. Change the address within this array using vi. For
-	     example, to driver 2 ISA boards with CAP address
-	     0x280 and 0x180 as 1st and 2nd board. Just to change
-	     the source code as follows.
-
-	     static int mxserBoardCAP[]
-	     = {0x280, 0x180, 0x00, 0x00};
-
-       3.5.4 Setup kernel configuration
-
-          Configure the kernel:
-
-            # cd /usr/src/linux
-            # make menuconfig
-
-          You will go into a menu-driven system. Please select [Character
-          devices][Non-standard serial port support], enable the [Moxa
-          SmartIO support] driver with "[*]" for built-in (not "[M]"), then
-          select [Exit] to exit this program.
-
-       3.5.5 Rebuild kernel
-	  The following are for Linux kernel rebuilding, for your
-          reference only.
-	  For appropriate details, please refer to the Linux document.
-
-	   a. cd /usr/src/linux
-	   b. make clean	     /* take a few minutes */
-	   c. make dep		     /* take a few minutes */
-	   d. make bzImage	     /* take probably 10-20 minutes */
-	   e. make install	     /* copy boot image to correct position */
-	   f. Please make sure the boot kernel (vmlinuz) is in the
-	      correct position.
-	   g. If you use 'lilo' utility, you should check /etc/lilo.conf
-	      'image' item specified the path which is the 'vmlinuz' path,
-	      or you will load wrong (or old) boot kernel image (vmlinuz).
-	      After checking /etc/lilo.conf, please run "lilo".
-
-	  Note that if the result of "make bzImage" is ERROR, then you have to
-	  go back to Linux configuration Setup. Type "make menuconfig" in
-          directory /usr/src/linux.
-
-
-       3.5.6 Make tty device and special file
-          # cd /moxa/mxser/driver
-          # ./msmknod
-
-       3.5.7 Make utility
-	  # cd /moxa/mxser/utility
-	  # make clean; make install
-
-       3.5.8 Reboot
-
-
-
-   3.6 Custom configuration
-       Although this driver already provides you default configuration, you
-       still can change the device name and major number. The instruction to
-       change these parameters are shown as below.
-
-       Change Device name
-       ------------------
-       If you'd like to use other device names instead of default naming
-       convention, all you have to do is to modify the internal code
-       within the shell script "msmknod". First, you have to open "msmknod"
-       by vi. Locate each line contains "ttyM" and "cum" and change them
-       to the device name you desired. "msmknod" creates the device names
-       you need next time executed.
-
-       Change Major number
-       -------------------
-       If major number 30 and 35 had been occupied, you may have to select
-       2 free major numbers for this driver. There are 3 steps to change
-       major numbers.
-
-       3.6.1 Find free major numbers
-	  In /proc/devices, you may find all the major numbers occupied
-	  in the system. Please select 2 major numbers that are available.
-	  e.g. 40, 45.
-       3.6.2 Create special files
-	  Run /moxa/mxser/driver/msmknod to create special files with
-	  specified major numbers.
-       3.6.3 Modify driver with new major number
-	  Run vi to open /moxa/mxser/driver/mxser.c. Locate the line
-	  contains "MXSERMAJOR". Change the content as below.
-	  #define	  MXSERMAJOR		  40
-	  #define	  MXSERCUMAJOR		  45
-       3.6.4 Run "make clean; make install" in /moxa/mxser/driver.
-
-   3.7 Verify driver installation
-       You may refer to /var/log/messages to check the latest status
-       log reported by this driver whenever it's activated.
-
------------------------------------------------------------------------------
-4. Utilities
-   There are 3 utilities contained in this driver. They are msdiag, msmon and
-   msterm. These 3 utilities are released in form of source code. They should
-   be compiled into executable file and copied into /usr/bin.
-
-   Before using these utilities, please load driver (refer 3.4 & 3.5) and
-   make sure you had run the "msmknod" utility.
-
-   msdiag - Diagnostic
-   --------------------
-   This utility provides the function to display what Moxa Smartio/Industio
-   board found by driver in the system.
-
-   msmon - Port Monitoring
-   -----------------------
-   This utility gives the user a quick view about all the MOXA ports'
-   activities. One can easily learn each port's total received/transmitted
-   (Rx/Tx) character count since the time when the monitoring is started.
-   Rx/Tx throughputs per second are also reported in interval basis (e.g.
-   the last 5 seconds) and in average basis (since the time the monitoring
-   is started). You can reset all ports' count by <HOME> key. <+> <->
-   (plus/minus) keys to change the displaying time interval. Press <ENTER>
-   on the port, that cursor stay, to view the port's communication
-   parameters, signal status, and input/output queue.
-
-   msterm - Terminal Emulation
-   ---------------------------
-   This utility provides data sending and receiving ability of all tty ports,
-   especially for MOXA ports. It is quite useful for testing simple
-   application, for example, sending AT command to a modem connected to the
-   port or used as a terminal for login purpose. Note that this is only a
-   dumb terminal emulation without handling full screen operation.
-
------------------------------------------------------------------------------
-5. Setserial
-
-   Supported Setserial parameters are listed as below.
-
-   uart		  set UART type(16450-->disable FIFO, 16550A-->enable FIFO)
-   close_delay	  set the amount of time(in 1/100 of a second) that DTR
-		  should be kept low while being closed.
-   closing_wait   set the amount of time(in 1/100 of a second) that the
-		  serial port should wait for data to be drained while
-		  being closed, before the receiver is disable.
-   spd_hi	  Use  57.6kb  when  the application requests 38.4kb.
-   spd_vhi	  Use  115.2kb	when  the application requests 38.4kb.
-   spd_shi	  Use  230.4kb	when  the application requests 38.4kb.
-   spd_warp	  Use  460.8kb	when  the application requests 38.4kb.
-   spd_normal	  Use  38.4kb  when  the application requests 38.4kb.
-   spd_cust	  Use  the custom divisor to set the speed when  the
-		  application requests 38.4kb.
-   divisor	  This option set the custom division.
-   baud_base	  This option set the base baud rate.
-
------------------------------------------------------------------------------
-6. Troubleshooting
-
-   The boot time error messages and solutions are stated as clearly as
-   possible. If all the possible solutions fail, please contact our technical
-   support team to get more help.
-
-
-   Error msg: More than 4 Moxa Smartio/Industio family boards found. Fifth board
-              and after are ignored.
-   Solution:
-   To avoid this problem, please unplug fifth and after board, because Moxa
-   driver supports up to 4 boards.
-
-   Error msg: Request_irq fail, IRQ(?) may be conflict with another device.
-   Solution:
-   Other PCI or ISA devices occupy the assigned IRQ. If you are not sure
-   which device causes the situation, please check /proc/interrupts to find
-   free IRQ and simply change another free IRQ for Moxa board.
-
-   Error msg: Board #: C1xx Series(CAP=xxx) interrupt number invalid.
-   Solution:
-   Each port within the same multiport board shares the same IRQ. Please set
-   one IRQ (IRQ doesn't equal to zero) for one Moxa board.
-
-   Error msg: No interrupt vector be set for Moxa ISA board(CAP=xxx).
-   Solution:
-   Moxa ISA board needs an interrupt vector.Please refer to user's manual
-   "Hardware Installation" chapter to set interrupt vector.
-
-   Error msg: Couldn't install MOXA Smartio/Industio family driver!
-   Solution:
-   Load Moxa driver fail, the major number may conflict with other devices.
-   Please refer to previous section 3.7 to change a free major number for
-   Moxa driver.
-
-   Error msg: Couldn't install MOXA Smartio/Industio family callout driver!
-   Solution:
-   Load Moxa callout driver fail, the callout device major number may
-   conflict with other devices. Please refer to previous section 3.7 to
-   change a free callout device major number for Moxa driver.

+		 Configuration program to setup ISA boards. Please note that
+                 this program can only be executed under DOS.
+
+   All the drivers and utilities are published in form of source code under
+   GNU General Public License in this version. Please refer to GNU General
+   Public License announcement in each source code file for more detail.
+
+   In Moxa's Web sites, you may always find latest driver at http://www.moxa.com/.
+
+   This version of driver can be installed as Loadable Module (Module driver)
+   or built-in into kernel (Static driver). You may refer to following
+   installation procedure for suitable one. Before you install the driver,
+   please refer to hardware installation procedure in the User's Manual.
+
+   We assume the user should be familiar with following documents.
+
+   - Serial-HOWTO
+   - Kernel-HOWTO
+
+2. System Requirement
+^^^^^^^^^^^^^^^^^^^^^
+
+   - Hardware platform: Intel x86 machine
+   - Kernel version: 2.4.x or 2.6.x
+   - gcc version 2.72 or later
+   - Maximum 4 boards can be installed in combination
+
+3. Installation
+^^^^^^^^^^^^^^^
+
+3.1 Hardware installation
+=========================
+
+   There are two types of buses, ISA and PCI, for Smartio/Industio
+   family multiport board.
+
+ISA board
+---------
+
+   You'll have to configure CAP address, I/O address, Interrupt Vector
+   as well as IRQ before installing this driver. Please refer to hardware
+   installation procedure in User's Manual before proceed any further.
+   Please make sure the JP1 is open after the ISA board is set properly.
+
+PCI/UPCI board
+--------------
+
+   You may need to adjust IRQ usage in BIOS to avoid from IRQ conflict
+   with other ISA devices. Please refer to hardware installation
+   procedure in User's Manual in advance.
+
+PCI IRQ Sharing
+---------------
+
+   Each port within the same multiport board shares the same IRQ. Up to
+   4 Moxa Smartio/Industio PCI Family multiport boards can be installed
+   together on one system and they can share the same IRQ.
+
+
+3.2 Driver files
+================
+
+   The driver file may be obtained from ftp, CD-ROM or floppy disk. The
+   first step, anyway, is to copy driver file "mxser.tgz" into specified
+   directory. e.g. /moxa. The execute commands as below::
+
+       # cd /
+       # mkdir moxa
+       # cd /moxa
+       # tar xvf /dev/fd0
+
+or::
+
+       # cd /
+       # mkdir moxa
+       # cd /moxa
+       # cp /mnt/cdrom/<driver directory>/mxser.tgz .
+       # tar xvfz mxser.tgz
+
+
+3.3 Device naming convention
+============================
+
+   You may find all the driver and utilities files in /moxa/mxser.
+   Following installation procedure depends on the model you'd like to
+   run the driver. If you prefer module driver, please refer to 3.4.
+   If static driver is required, please refer to 3.5.
+
+Dialin and callout port
+-----------------------
+
+   This driver remains traditional serial device properties. There are
+   two special file name for each serial port. One is dial-in port
+   which is named "ttyMxx". For callout port, the naming convention
+   is "cumxx".
+
+Device naming when more than 2 boards installed
+-----------------------------------------------
+
+   Naming convention for each Smartio/Industio multiport board is
+   pre-defined as below.
+
+   ============ ===============       ==============
+   Board Num.	 Dial-in Port	      Callout port
+   1st board	ttyM0  - ttyM7	      cum0  - cum7
+   2nd board	ttyM8  - ttyM15       cum8  - cum15
+   3rd board	ttyM16 - ttyM23       cum16 - cum23
+   4th board	ttyM24 - ttym31       cum24 - cum31
+   ============ ===============       ==============
+
+.. note::
+
+   Under Kernel 2.6 and upper, the cum Device is Obsolete. So use ttyM*
+   device instead.
+
+Board sequence
+--------------
+
+   This driver will activate ISA boards according to the parameter set
+   in the driver. After all specified ISA board activated, PCI board
+   will be installed in the system automatically driven.
+   Therefore the board number is sorted by the CAP address of ISA boards.
+   For PCI boards, their sequence will be after ISA boards and C168H/PCI
+   has higher priority than C104H/PCI boards.
+
+3.4 Module driver configuration
+===============================
+
+   Module driver is easiest way to install. If you prefer static driver
+   installation, please skip this paragraph.
+
+
+   ------------- Prepare to use the MOXA driver --------------------
+
+3.4.1 Create tty device with correct major number
+-------------------------------------------------
+
+   Before using MOXA driver, your system must have the tty devices
+   which are created with driver's major number. We offer one shell
+   script "msmknod" to simplify the procedure.
+   This step is only needed to be executed once. But you still
+   need to do this procedure when:
+
+   a. You change the driver's major number. Please refer the "3.7"
+      section.
+   b. Your total installed MOXA boards number is changed. Maybe you
+      add/delete one MOXA board.
+   c. You want to change the tty name. This needs to modify the
+      shell script "msmknod"
+
+   The procedure is::
+
+	 # cd /moxa/mxser/driver
+	 # ./msmknod
+
+   This shell script will require the major number for dial-in
+   device and callout device to create tty device. You also need
+   to specify the total installed MOXA board number. Default major
+   numbers for dial-in device and callout device are 30, 35. If
+   you need to change to other number, please refer section "3.7"
+   for more detailed procedure.
+   Msmknod will delete any special files occupying the same device
+   naming.
+
+3.4.2 Build the MOXA driver and utilities
+-----------------------------------------
+
+   Before using the MOXA driver and utilities, you need compile the
+   all the source code. This step is only need to be executed once.
+   But you still re-compile the source code if you modify the source
+   code. For example, if you change the driver's major number (see
+   "3.7" section), then you need to do this step again.
+
+   Find "Makefile" in /moxa/mxser, then run
+
+	 # make clean; make install
+
+   ..note::
+
+	 For Red Hat 9, Red Hat Enterprise Linux AS3/ES3/WS3 & Fedora Core1:
+	 # make clean; make installsp1
+
+	 For Red Hat Enterprise Linux AS4/ES4/WS4:
+	 # make clean; make installsp2
+
+   The driver files "mxser.o" and utilities will be properly compiled
+   and copied to system directories respectively.
+
+------------- Load MOXA driver--------------------
+
+3.4.3 Load the MOXA driver
+--------------------------
+
+   ::
+
+	 # modprobe mxser <argument>
+
+   will activate the module driver. You may run "lsmod" to check
+   if "mxser" is activated. If the MOXA board is ISA board, the
+   <argument> is needed. Please refer to section "3.4.5" for more
+   information.
+
+------------- Load MOXA driver on boot --------------------
+
+3.4.4 Load the mxser driver
+---------------------------
+
+
+   For the above description, you may manually execute
+   "modprobe mxser" to activate this driver and run
+   "rmmod mxser" to remove it.
+
+   However, it's better to have a boot time configuration to
+   eliminate manual operation. Boot time configuration can be
+   achieved by rc file. We offer one "rc.mxser" file to simplify
+   the procedure under "moxa/mxser/driver".
+
+   But if you use ISA board, please modify the "modprobe ..." command
+   to add the argument (see "3.4.5" section). After modifying the
+   rc.mxser, please try to execute "/moxa/mxser/driver/rc.mxser"
+   manually to make sure the modification is ok. If any error
+   encountered, please try to modify again. If the modification is
+   completed, follow the below step.
+
+   Run following command for setting rc files::
+
+	 # cd /moxa/mxser/driver
+	 # cp ./rc.mxser /etc/rc.d
+	 # cd /etc/rc.d
+
+   Check "rc.serial" is existed or not. If "rc.serial" doesn't exist,
+   create it by vi, run "chmod 755 rc.serial" to change the permission.
+
+   Add "/etc/rc.d/rc.mxser" in last line.
+
+   Reboot and check if moxa.o activated by "lsmod" command.
+
+3.4.5. specify CAP address
+--------------------------
+
+   If you'd like to drive Smartio/Industio ISA boards in the system,
+   you'll have to add parameter to specify CAP address of given
+   board while activating "mxser.o". The format for parameters are
+   as follows.::
+
+	   modprobe mxser ioaddr=0x???,0x???,0x???,0x???
+				  |  |  |    |
+				  |  |  |    +- 4th ISA board
+				  |  |  +------ 3rd ISA board
+				  |  +------------ 2nd ISA board
+				  +-------------------1st ISA board
+
+3.5 Static driver configuration for Linux kernel 2.4.x and 2.6.x
+================================================================
+
+    Note:
+          To use static driver, you must install the linux kernel
+          source package.
+
+3.5.1 Backup the built-in driver in the kernel
+----------------------------------------------
+
+    ::
+
+       # cd /usr/src/linux/drivers/char
+       # mv mxser.c mxser.c.old
+
+       For Red Hat 7.x user, you need to create link:
+       # cd /usr/src
+       # ln -s linux-2.4 linux
+
+3.5.2 Create link
+-----------------
+    ::
+
+	  # cd /usr/src/linux/drivers/char
+	  # ln -s /moxa/mxser/driver/mxser.c mxser.c
+
+3.5.3 Add CAP address list for ISA boards.
+------------------------------------------
+
+    For PCI boards user, please skip this step.
+
+    In module mode, the CAP address for ISA board is given by
+    parameter. In static driver configuration, you'll have to
+    assign it within driver's source code. If you will not
+    install any ISA boards, you may skip to next portion.
+    The instructions to modify driver source code are as
+    below.
+
+    a. run::
+
+	# cd /moxa/mxser/driver
+	# vi mxser.c
+
+    b. Find the array mxserBoardCAP[] as below::
+
+	  static int mxserBoardCAP[] = {0x00, 0x00, 0x00, 0x00};
+
+    c. Change the address within this array using vi. For
+       example, to driver 2 ISA boards with CAP address
+       0x280 and 0x180 as 1st and 2nd board. Just to change
+       the source code as follows::
+
+	  static int mxserBoardCAP[] = {0x280, 0x180, 0x00, 0x00};
+
+3.5.4 Setup kernel configuration
+--------------------------------
+
+    Configure the kernel::
+
+      # cd /usr/src/linux
+      # make menuconfig
+
+    You will go into a menu-driven system. Please select [Character
+    devices][Non-standard serial port support], enable the [Moxa
+    SmartIO support] driver with "[*]" for built-in (not "[M]"), then
+    select [Exit] to exit this program.
+
+3.5.5 Rebuild kernel
+--------------------
+
+    The following are for Linux kernel rebuilding, for your
+    reference only.
+
+    For appropriate details, please refer to the Linux document:
+
+        a. Run the following commands::
+
+	     cd /usr/src/linux
+	     make clean		     # take a few minutes
+	     make dep		     # take a few minutes
+	     make bzImage	     # take probably 10-20 minutes
+	     make install	     # copy boot image to correct position
+
+	f. Please make sure the boot kernel (vmlinuz) is in the
+	   correct position.
+	g. If you use 'lilo' utility, you should check /etc/lilo.conf
+	   'image' item specified the path which is the 'vmlinuz' path,
+	   or you will load wrong (or old) boot kernel image (vmlinuz).
+	   After checking /etc/lilo.conf, please run "lilo".
+
+	  Note that if the result of "make bzImage" is ERROR, then you have to
+	  go back to Linux configuration Setup. Type "make menuconfig" in
+          directory /usr/src/linux.
+
+
+3.5.6 Make tty device and special file
+--------------------------------------
+
+    ::
+       # cd /moxa/mxser/driver
+       # ./msmknod
+
+3.5.7 Make utility
+------------------
+
+    ::
+
+	  # cd /moxa/mxser/utility
+	  # make clean; make install
+
+3.5.8 Reboot
+------------
+
+
+
+3.6 Custom configuration
+========================
+
+    Although this driver already provides you default configuration, you
+    still can change the device name and major number. The instruction to
+    change these parameters are shown as below.
+
+a. Change Device name
+
+    If you'd like to use other device names instead of default naming
+    convention, all you have to do is to modify the internal code
+    within the shell script "msmknod". First, you have to open "msmknod"
+    by vi. Locate each line contains "ttyM" and "cum" and change them
+    to the device name you desired. "msmknod" creates the device names
+    you need next time executed.
+
+b. Change Major number
+
+    If major number 30 and 35 had been occupied, you may have to select
+    2 free major numbers for this driver. There are 3 steps to change
+    major numbers.
+
+3.6.1 Find free major numbers
+-----------------------------
+
+    In /proc/devices, you may find all the major numbers occupied
+    in the system. Please select 2 major numbers that are available.
+    e.g. 40, 45.
+
+3.6.2 Create special files
+--------------------------
+
+   Run /moxa/mxser/driver/msmknod to create special files with
+   specified major numbers.
+
+3.6.3 Modify driver with new major number
+-----------------------------------------
+
+   Run vi to open /moxa/mxser/driver/mxser.c. Locate the line
+   contains "MXSERMAJOR". Change the content as below::
+
+	  #define	  MXSERMAJOR		  40
+	  #define	  MXSERCUMAJOR		  45
+
+    3.6.4 Run "make clean; make install" in /moxa/mxser/driver.
+
+3.7 Verify driver installation
+==============================
+
+    You may refer to /var/log/messages to check the latest status
+    log reported by this driver whenever it's activated.
+
+4. Utilities
+^^^^^^^^^^^^
+
+   There are 3 utilities contained in this driver. They are msdiag, msmon and
+   msterm. These 3 utilities are released in form of source code. They should
+   be compiled into executable file and copied into /usr/bin.
+
+   Before using these utilities, please load driver (refer 3.4 & 3.5) and
+   make sure you had run the "msmknod" utility.
+
+msdiag - Diagnostic
+===================
+
+   This utility provides the function to display what Moxa Smartio/Industio
+   board found by driver in the system.
+
+msmon - Port Monitoring
+=======================
+
+   This utility gives the user a quick view about all the MOXA ports'
+   activities. One can easily learn each port's total received/transmitted
+   (Rx/Tx) character count since the time when the monitoring is started.
+
+   Rx/Tx throughputs per second are also reported in interval basis (e.g.
+   the last 5 seconds) and in average basis (since the time the monitoring
+   is started). You can reset all ports' count by <HOME> key. <+> <->
+   (plus/minus) keys to change the displaying time interval. Press <ENTER>
+   on the port, that cursor stay, to view the port's communication
+   parameters, signal status, and input/output queue.
+
+msterm - Terminal Emulation
+===========================
+
+   This utility provides data sending and receiving ability of all tty ports,
+   especially for MOXA ports. It is quite useful for testing simple
+   application, for example, sending AT command to a modem connected to the
+   port or used as a terminal for login purpose. Note that this is only a
+   dumb terminal emulation without handling full screen operation.
+
+5. Setserial
+^^^^^^^^^^^^
+
+   Supported Setserial parameters are listed as below.
+
+   ============== =========================================================
+   uart		  set UART type(16450-->disable FIFO, 16550A-->enable FIFO)
+   close_delay	  set the amount of time(in 1/100 of a second) that DTR
+		  should be kept low while being closed.
+   closing_wait   set the amount of time(in 1/100 of a second) that the
+		  serial port should wait for data to be drained while
+		  being closed, before the receiver is disable.
+   spd_hi	  Use  57.6kb  when  the application requests 38.4kb.
+   spd_vhi	  Use  115.2kb	when  the application requests 38.4kb.
+   spd_shi	  Use  230.4kb	when  the application requests 38.4kb.
+   spd_warp	  Use  460.8kb	when  the application requests 38.4kb.
+   spd_normal	  Use  38.4kb  when  the application requests 38.4kb.
+   spd_cust	  Use  the custom divisor to set the speed when  the
+		  application requests 38.4kb.
+   divisor	  This option set the custom division.
+   baud_base	  This option set the base baud rate.
+   ============== =========================================================
+
+6. Troubleshooting
+^^^^^^^^^^^^^^^^^^
+
+   The boot time error messages and solutions are stated as clearly as
+   possible. If all the possible solutions fail, please contact our technical
+   support team to get more help.
+
+
+   Error msg:
+	      More than 4 Moxa Smartio/Industio family boards found. Fifth board
+              and after are ignored.
+
+   Solution:
+   To avoid this problem, please unplug fifth and after board, because Moxa
+   driver supports up to 4 boards.
+
+   Error msg:
+	      Request_irq fail, IRQ(?) may be conflict with another device.
+
+   Solution:
+   Other PCI or ISA devices occupy the assigned IRQ. If you are not sure
+   which device causes the situation, please check /proc/interrupts to find
+   free IRQ and simply change another free IRQ for Moxa board.
+
+   Error msg:
+	      Board #: C1xx Series(CAP=xxx) interrupt number invalid.
+
+   Solution:
+   Each port within the same multiport board shares the same IRQ. Please set
+   one IRQ (IRQ doesn't equal to zero) for one Moxa board.
+
+   Error msg:
+	      No interrupt vector be set for Moxa ISA board(CAP=xxx).
+
+   Solution:
+   Moxa ISA board needs an interrupt vector.Please refer to user's manual
+   "Hardware Installation" chapter to set interrupt vector.
+
+   Error msg:
+              Couldn't install MOXA Smartio/Industio family driver!
+
+   Solution:
+   Load Moxa driver fail, the major number may conflict with other devices.
+   Please refer to previous section 3.7 to change a free major number for
+   Moxa driver.
+
+   Error msg:
+              Couldn't install MOXA Smartio/Industio family callout driver!
+
+   Solution:
+   Load Moxa callout driver fail, the callout device major number may
+   conflict with other devices. Please refer to previous section 3.7 to
+   change a free callout device major number for Moxa driver.

+GSM 0710 tty multiplexor HOWTO
+==============================
+
+This line discipline implements the GSM 07.10 multiplexing protocol
+detailed in the following 3GPP document:
+
+	http://www.3gpp.org/ftp/Specs/archive/07_series/07.10/0710-720.zip
+
+This document give some hints on how to use this driver with GPRS and 3G
+modems connected to a physical serial port.
+
+How to use it
+-------------
+1. initialize the modem in 0710 mux mode (usually AT+CMUX= command) through
+   its serial port. Depending on the modem used, you can pass more or less
+   parameters to this command,
+2. switch the serial line to using the n_gsm line discipline by using
+   TIOCSETD ioctl,
+3. configure the mux using GSMIOC_GETCONF / GSMIOC_SETCONF ioctl,
+
+Major parts of the initialization program :
+(a good starting point is util-linux-ng/sys-utils/ldattach.c)::
+
+  #include <linux/gsmmux.h>
+  #define N_GSM0710	21	/* GSM 0710 Mux */
+  #define DEFAULT_SPEED	B115200
+  #define SERIAL_PORT	/dev/ttyS0
+
+	int ldisc = N_GSM0710;
+	struct gsm_config c;
+	struct termios configuration;
+
+	/* open the serial port connected to the modem */
+	fd = open(SERIAL_PORT, O_RDWR | O_NOCTTY | O_NDELAY);
+
+	/* configure the serial port : speed, flow control ... */
+
+	/* send the AT commands to switch the modem to CMUX mode
+	   and check that it's successful (should return OK) */
+	write(fd, "AT+CMUX=0\r", 10);
+
+	/* experience showed that some modems need some time before
+	   being able to answer to the first MUX packet so a delay
+	   may be needed here in some case */
+	sleep(3);
+
+	/* use n_gsm line discipline */
+	ioctl(fd, TIOCSETD, &ldisc);
+
+	/* get n_gsm configuration */
+	ioctl(fd, GSMIOC_GETCONF, &c);
+	/* we are initiator and need encoding 0 (basic) */
+	c.initiator = 1;
+	c.encapsulation = 0;
+	/* our modem defaults to a maximum size of 127 bytes */
+	c.mru = 127;
+	c.mtu = 127;
+	/* set the new configuration */
+	ioctl(fd, GSMIOC_SETCONF, &c);
+
+	/* and wait for ever to keep the line discipline enabled */
+	daemon(0,0);
+	pause();
+
+4. create the devices corresponding to the "virtual" serial ports (take care,
+   each modem has its configuration and some DLC have dedicated functions,
+   for example GPS), starting with minor 1 (DLC0 is reserved for the management
+   of the mux)::
+
+     MAJOR=`cat /proc/devices |grep gsmtty | awk '{print $1}`
+     for i in `seq 1 4`; do
+	mknod /dev/ttygsm$i c $MAJOR $i
+     done
+
+5. use these devices as plain serial ports.
+
+   for example, it's possible:
+
+   - and to use gnokii to send / receive SMS on ttygsm1
+   - to use ppp to establish a datalink on ttygsm2
+
+6. first close all virtual ports before closing the physical port.
+
+   Note that after closing the physical port the modem is still in multiplexing
+   mode. This may prevent a successful re-opening of the port later. To avoid
+   this situation either reset the modem if your hardware allows that or send
+   a disconnect command frame manually before initializing the multiplexing mode
+   for the second time. The byte sequence for the disconnect command frame is::
+
+      0xf9, 0x03, 0xef, 0x03, 0xc3, 0x16, 0xf9.

+================================================
+Comtrol(tm) RocketPort(R)/RocketModem(TM) Series
+================================================
+
+Device Driver for the Linux Operating System
+============================================
+
+Product overview
+----------------
+
+This driver provides a loadable kernel driver for the Comtrol RocketPort
+and RocketModem PCI boards. These boards provide, 2, 4, 8, 16, or 32
+high-speed serial ports or modems.  This driver supports up to a combination
+of four RocketPort or RocketModems boards in one machine simultaneously.
+This file assumes that you are using the RocketPort driver which is
+integrated into the kernel sources.
+
+The driver can also be installed as an external module using the usual
+"make;make install" routine.  This external module driver, obtainable
+from the Comtrol website listed below, is useful for updating the driver
+or installing it into kernels which do not have the driver configured
+into them.  Installations instructions for the external module
+are in the included README and HW_INSTALL files.
+
+RocketPort ISA and RocketModem II PCI boards currently are only supported by
+this driver in module form.
+
+The RocketPort ISA board requires I/O ports to be configured by the DIP
+switches on the board.  See the section "ISA Rocketport Boards" below for
+information on how to set the DIP switches.
+
+You pass the I/O port to the driver using the following module parameters:
+
+board1:
+	I/O port for the first ISA board
+board2:
+	I/O port for the second ISA board
+board3:
+	I/O port for the third ISA board
+board4:
+	I/O port for the fourth ISA board
+
+There is a set of utilities and scripts provided with the external driver
+(downloadable from http://www.comtrol.com) that ease the configuration and
+setup of the ISA cards.
+
+The RocketModem II PCI boards require firmware to be loaded into the card
+before it will function.  The driver has only been tested as a module for this
+board.
+
+Installation Procedures
+-----------------------
+
+RocketPort/RocketModem PCI cards require no driver configuration, they are
+automatically detected and configured.
+
+The RocketPort driver can be installed as a module (recommended) or built
+into the kernel. This is selected, as for other drivers, through the `make config`
+command from the root of the Linux source tree during the kernel build process.
+
+The RocketPort/RocketModem serial ports installed by this driver are assigned
+device major number 46, and will be named /dev/ttyRx, where x is the port number
+starting at zero (ex. /dev/ttyR0, /devttyR1, ...).  If you have multiple cards
+installed in the system, the mapping of port names to serial ports is displayed
+in the system log at /var/log/messages.
+
+If installed as a module, the module must be loaded.  This can be done
+manually by entering "modprobe rocket".  To have the module loaded automatically
+upon system boot, edit a `/etc/modprobe.d/*.conf` file and add the line
+"alias char-major-46 rocket".
+
+In order to use the ports, their device names (nodes) must be created with mknod.
+This is only required once, the system will retain the names once created.  To
+create the RocketPort/RocketModem device names, use the command
+"mknod /dev/ttyRx c 46 x" where x is the port number starting at zero.
+
+For example::
+
+	> mknod /dev/ttyR0 c 46 0
+	> mknod /dev/ttyR1 c 46 1
+	> mknod /dev/ttyR2 c 46 2
+
+The Linux script MAKEDEV will create the first 16 ttyRx device names (nodes)
+for you::
+
+	>/dev/MAKEDEV ttyR
+
+ISA Rocketport Boards
+---------------------
+
+You must assign and configure the I/O addresses used by the ISA Rocketport
+card before installing and using it.  This is done by setting a set of DIP
+switches on the Rocketport board.
+
+
+Setting the I/O address
+-----------------------
+
+Before installing RocketPort(R) or RocketPort RA boards, you must find
+a range of I/O addresses for it to use. The first RocketPort card
+requires a 68-byte contiguous block of I/O addresses, starting at one
+of the following: 0x100h, 0x140h, 0x180h, 0x200h, 0x240h, 0x280h,
+0x300h, 0x340h, 0x380h.  This I/O address must be reflected in the DIP
+switches of *all* of the Rocketport cards.
+
+The second, third, and fourth RocketPort cards require a 64-byte

+I/O addresses: 0x100h, 0x140h, 0x180h, 0x1C0h, 0x200h, 0x240h, 0x280h,
+0x2C0h, 0x300h, 0x340h, 0x380h, 0x3C0h.  The I/O address used by the
+second, third, and fourth Rocketport cards (if present) are set via
+software control.  The DIP switch settings for the I/O address must be
+set to the value of the first Rocketport cards.
+
+In order to distinguish each of the card from the others, each card
+must have a unique board ID set on the dip switches.  The first
+Rocketport board must be set with the DIP switches corresponding to
+the first board, the second board must be set with the DIP switches
+corresponding to the second board, etc.  IMPORTANT: The board ID is
+the only place where the DIP switch settings should differ between the
+various Rocketport boards in a system.
+
+The I/O address range used by any of the RocketPort cards must not
+conflict with any other cards in the system, including other
+RocketPort cards.  Below, you will find a list of commonly used I/O
+address ranges which may be in use by other devices in your system.
+On a Linux system, "cat /proc/ioports" will also be helpful in
+identifying what I/O addresses are being used by devices on your
+system.
+
+Remember, the FIRST RocketPort uses 68 I/O addresses.  So, if you set it
+for 0x100, it will occupy 0x100 to 0x143.  This would mean that you
+CAN NOT set the second, third or fourth board for address 0x140 since
+the first 4 bytes of that range are used by the first board.  You would
+need to set the second, third, or fourth board to one of the next available
+blocks such as 0x180.

-Comtrol(tm) RocketPort(R)/RocketModem(TM) Series 
-Device Driver for the Linux Operating System
-
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
-
-PRODUCT OVERVIEW
-----------------
-
-This driver provides a loadable kernel driver for the Comtrol RocketPort
-and RocketModem PCI boards. These boards provide, 2, 4, 8, 16, or 32 
-high-speed serial ports or modems.  This driver supports up to a combination
-of four RocketPort or RocketModems boards in one machine simultaneously.
-This file assumes that you are using the RocketPort driver which is
-integrated into the kernel sources.  
-
-The driver can also be installed as an external module using the usual 
-"make;make install" routine.  This external module driver, obtainable 
-from the Comtrol website listed below, is useful for updating the driver
-or installing it into kernels which do not have the driver configured
-into them.  Installations instructions for the external module
-are in the included README and HW_INSTALL files.
-
-RocketPort ISA and RocketModem II PCI boards currently are only supported by
-this driver in module form.
-
-The RocketPort ISA board requires I/O ports to be configured by the DIP
-switches on the board.  See the section "ISA Rocketport Boards" below for
-information on how to set the DIP switches.
-
-You pass the I/O port to the driver using the following module parameters:
-
-board1 :	I/O port for the first ISA board
-board2 :	I/O port for the second ISA board
-board3 :	I/O port for the third ISA board
-board4 :	I/O port for the fourth ISA board
-
-There is a set of utilities and scripts provided with the external driver
-( downloadable from http://www.comtrol.com ) that ease the configuration and
-setup of the ISA cards.
-
-The RocketModem II PCI boards require firmware to be loaded into the card
-before it will function.  The driver has only been tested as a module for this
-board.
-

-
-INSTALLATION PROCEDURES
------------------------
-
-RocketPort/RocketModem PCI cards require no driver configuration, they are 
-automatically detected and configured.
-
-The RocketPort driver can be installed as a module (recommended) or built 
-into the kernel. This is selected, as for other drivers, through the `make config`
-command from the root of the Linux source tree during the kernel build process. 
-
-The RocketPort/RocketModem serial ports installed by this driver are assigned
-device major number 46, and will be named /dev/ttyRx, where x is the port number 
-starting at zero (ex. /dev/ttyR0, /devttyR1, ...).  If you have multiple cards
-installed in the system, the mapping of port names to serial ports is displayed
-in the system log at /var/log/messages.
-
-If installed as a module, the module must be loaded.  This can be done
-manually by entering "modprobe rocket".  To have the module loaded automatically
-upon system boot, edit a /etc/modprobe.d/*.conf file and add the line
-"alias char-major-46 rocket".
-
-In order to use the ports, their device names (nodes) must be created with mknod.
-This is only required once, the system will retain the names once created.  To 
-create the RocketPort/RocketModem device names, use the command 
-"mknod /dev/ttyRx c 46 x" where x is the port number starting at zero.  For example:
-
->mknod /dev/ttyR0 c 46 0
->mknod /dev/ttyR1 c 46 1
->mknod /dev/ttyR2 c 46 2  
-
-The Linux script MAKEDEV will create the first 16 ttyRx device names (nodes)
-for you:
-
->/dev/MAKEDEV ttyR
-

-
-ISA Rocketport Boards
----------------------
-
-You must assign and configure the I/O addresses used by the ISA Rocketport
-card before installing and using it.  This is done by setting a set of DIP
-switches on the Rocketport board.
-
-
-SETTING THE I/O ADDRESS
------------------------
-
-Before installing RocketPort(R) or RocketPort RA boards, you must find
-a range of I/O addresses for it to use. The first RocketPort card
-requires a 68-byte contiguous block of I/O addresses, starting at one
-of the following: 0x100h, 0x140h, 0x180h, 0x200h, 0x240h, 0x280h,
-0x300h, 0x340h, 0x380h.  This I/O address must be reflected in the DIP
-switches of *all* of the Rocketport cards.
-
-The second, third, and fourth RocketPort cards require a 64-byte
-contiguous block of I/O addresses, starting at one of the following
-I/O addresses: 0x100h, 0x140h, 0x180h, 0x1C0h, 0x200h, 0x240h, 0x280h,
-0x2C0h, 0x300h, 0x340h, 0x380h, 0x3C0h.  The I/O address used by the
-second, third, and fourth Rocketport cards (if present) are set via
-software control.  The DIP switch settings for the I/O address must be
-set to the value of the first Rocketport cards.
-
-In order to distinguish each of the card from the others, each card
-must have a unique board ID set on the dip switches.  The first
-Rocketport board must be set with the DIP switches corresponding to
-the first board, the second board must be set with the DIP switches
-corresponding to the second board, etc.  IMPORTANT: The board ID is
-the only place where the DIP switch settings should differ between the
-various Rocketport boards in a system.
-
-The I/O address range used by any of the RocketPort cards must not
-conflict with any other cards in the system, including other
-RocketPort cards.  Below, you will find a list of commonly used I/O
-address ranges which may be in use by other devices in your system.
-On a Linux system, "cat /proc/ioports" will also be helpful in
-identifying what I/O addresses are being used by devices on your
-system.
-
-Remember, the FIRST RocketPort uses 68 I/O addresses.  So, if you set it
-for 0x100, it will occupy 0x100 to 0x143.  This would mean that you
-CAN NOT set the second, third or fourth board for address 0x140 since
-the first 4 bytes of that range are used by the first board.  You would
-need to set the second, third, or fourth board to one of the next available
-blocks such as 0x180.

+ISO7816 Serial Communications
+=============================
+
+1. Introduction
+===============
+
+  ISO/IEC7816 is a series of standards specifying integrated circuit cards (ICC)
+  also known as smart cards.
+
+2. Hardware-related considerations
+==================================
+
+  Some CPUs/UARTs (e.g., Microchip AT91) contain a built-in mode capable of
+  handling communication with a smart card.
+
+  For these microcontrollers, the Linux driver should be made capable of
+  working in both modes, and proper ioctls (see later) should be made
+  available at user-level to allow switching from one mode to the other, and
+  vice versa.
+
+3. Data Structures Already Available in the Kernel
+==================================================
+
+  The Linux kernel provides the serial_iso7816 structure (see [1]) to handle
+  ISO7816 communications. This data structure is used to set and configure
+  ISO7816 parameters in ioctls.
+
+  Any driver for devices capable of working both as RS232 and ISO7816 should
+  implement the iso7816_config callback in the uart_port structure. The
+  serial_core calls iso7816_config to do the device specific part in response
+  to TIOCGISO7816 and TIOCSISO7816 ioctls (see below). The iso7816_config
+  callback receives a pointer to struct serial_iso7816.
+
+4. Usage from user-level
+========================
+
+  From user-level, ISO7816 configuration can be get/set using the previous
+  ioctls. For instance, to set ISO7816 you can use the following code::
+
+	#include <linux/serial.h>
+
+	/* Include definition for ISO7816 ioctls: TIOCSISO7816 and TIOCGISO7816 */
+	#include <sys/ioctl.h>
+
+	/* Open your specific device (e.g., /dev/mydevice): */
+	int fd = open ("/dev/mydevice", O_RDWR);
+	if (fd < 0) {
+		/* Error handling. See errno. */
+	}
+
+	struct serial_iso7816 iso7816conf;
+
+	/* Reserved fields as to be zeroed */
+	memset(&iso7816conf, 0, sizeof(iso7816conf));
+
+	/* Enable ISO7816 mode: */
+	iso7816conf.flags |= SER_ISO7816_ENABLED;
+
+	/* Select the protocol: */
+	/* T=0 */
+	iso7816conf.flags |= SER_ISO7816_T(0);
+	/* or T=1 */
+	iso7816conf.flags |= SER_ISO7816_T(1);
+
+	/* Set the guard time: */
+	iso7816conf.tg = 2;
+
+	/* Set the clock frequency*/
+	iso7816conf.clk = 3571200;
+
+	/* Set transmission factors: */
+	iso7816conf.sc_fi = 372;
+	iso7816conf.sc_di = 1;
+
+	if (ioctl(fd_usart, TIOCSISO7816, &iso7816conf) < 0) {
+		/* Error handling. See errno. */
+	}
+
+	/* Use read() and write() syscalls here... */
+
+	/* Close the device when finished: */
+	if (close (fd) < 0) {
+		/* Error handling. See errno. */

+===========================
+RS485 Serial Communications
+===========================
+
+1. Introduction
+===============
+
+   EIA-485, also known as TIA/EIA-485 or RS-485, is a standard defining the
+   electrical characteristics of drivers and receivers for use in balanced
+   digital multipoint systems.
+   This standard is widely used for communications in industrial automation
+   because it can be used effectively over long distances and in electrically
+   noisy environments.
+
+2. Hardware-related Considerations
+==================================
+
+   Some CPUs/UARTs (e.g., Atmel AT91 or 16C950 UART) contain a built-in
+   half-duplex mode capable of automatically controlling line direction by
+   toggling RTS or DTR signals. That can be used to control external
+   half-duplex hardware like an RS485 transceiver or any RS232-connected
+   half-duplex devices like some modems.
+
+   For these microcontrollers, the Linux driver should be made capable of
+   working in both modes, and proper ioctls (see later) should be made
+   available at user-level to allow switching from one mode to the other, and
+   vice versa.
+
+3. Data Structures Already Available in the Kernel
+==================================================
+
+   The Linux kernel provides the serial_rs485 structure (see [1]) to handle
+   RS485 communications. This data structure is used to set and configure RS485
+   parameters in the platform data and in ioctls.
+
+   The device tree can also provide RS485 boot time parameters (see [2]
+   for bindings). The driver is in charge of filling this data structure from
+   the values given by the device tree.
+
+   Any driver for devices capable of working both as RS232 and RS485 should
+   implement the rs485_config callback in the uart_port structure. The
+   serial_core calls rs485_config to do the device specific part in response
+   to TIOCSRS485 and TIOCGRS485 ioctls (see below). The rs485_config callback
+   receives a pointer to struct serial_rs485.
+
+4. Usage from user-level
+========================
+
+   From user-level, RS485 configuration can be get/set using the previous
+   ioctls. For instance, to set RS485 you can use the following code::
+
+	#include <linux/serial.h>
+
+	/* Include definition for RS485 ioctls: TIOCGRS485 and TIOCSRS485 */
+	#include <sys/ioctl.h>
+
+	/* Open your specific device (e.g., /dev/mydevice): */
+	int fd = open ("/dev/mydevice", O_RDWR);
+	if (fd < 0) {
+		/* Error handling. See errno. */
+	}
+

-                        RS485 SERIAL COMMUNICATIONS
-
-1. INTRODUCTION
-
-   EIA-485, also known as TIA/EIA-485 or RS-485, is a standard defining the
-   electrical characteristics of drivers and receivers for use in balanced
-   digital multipoint systems.
-   This standard is widely used for communications in industrial automation
-   because it can be used effectively over long distances and in electrically
-   noisy environments.
-
-2. HARDWARE-RELATED CONSIDERATIONS
-
-   Some CPUs/UARTs (e.g., Atmel AT91 or 16C950 UART) contain a built-in
-   half-duplex mode capable of automatically controlling line direction by
-   toggling RTS or DTR signals. That can be used to control external
-   half-duplex hardware like an RS485 transceiver or any RS232-connected
-   half-duplex devices like some modems.
-
-   For these microcontrollers, the Linux driver should be made capable of
-   working in both modes, and proper ioctls (see later) should be made
-   available at user-level to allow switching from one mode to the other, and
-   vice versa.
-
-3. DATA STRUCTURES ALREADY AVAILABLE IN THE KERNEL
-
-   The Linux kernel provides the serial_rs485 structure (see [1]) to handle
-   RS485 communications. This data structure is used to set and configure RS485
-   parameters in the platform data and in ioctls.
-
-   The device tree can also provide RS485 boot time parameters (see [2]
-   for bindings). The driver is in charge of filling this data structure from
-   the values given by the device tree.
-
-   Any driver for devices capable of working both as RS232 and RS485 should
-   implement the rs485_config callback in the uart_port structure. The
-   serial_core calls rs485_config to do the device specific part in response
-   to TIOCSRS485 and TIOCGRS485 ioctls (see below). The rs485_config callback
-   receives a pointer to struct serial_rs485.
-
-4. USAGE FROM USER-LEVEL
-
-   From user-level, RS485 configuration can be get/set using the previous
-   ioctls. For instance, to set RS485 you can use the following code:
-
-	#include <linux/serial.h>
-
-	/* Include definition for RS485 ioctls: TIOCGRS485 and TIOCSRS485 */
-	#include <sys/ioctl.h>
-
-	/* Open your specific device (e.g., /dev/mydevice): */
-	int fd = open ("/dev/mydevice", O_RDWR);
-	if (fd < 0) {
-		/* Error handling. See errno. */
-	}
-
-	struct serial_rs485 rs485conf;
-
-	/* Enable RS485 mode: */
-	rs485conf.flags |= SER_RS485_ENABLED;
-
-	/* Set logical level for RTS pin equal to 1 when sending: */
-	rs485conf.flags |= SER_RS485_RTS_ON_SEND;
-	/* or, set logical level for RTS pin equal to 0 when sending: */
-	rs485conf.flags &= ~(SER_RS485_RTS_ON_SEND);
-
-	/* Set logical level for RTS pin equal to 1 after sending: */
-	rs485conf.flags |= SER_RS485_RTS_AFTER_SEND;
-	/* or, set logical level for RTS pin equal to 0 after sending: */
-	rs485conf.flags &= ~(SER_RS485_RTS_AFTER_SEND);
-
-	/* Set rts delay before send, if needed: */
-	rs485conf.delay_rts_before_send = ...;
-
-	/* Set rts delay after send, if needed: */
-	rs485conf.delay_rts_after_send = ...;
-
-	/* Set this flag if you want to receive data even while sending data */
-	rs485conf.flags |= SER_RS485_RX_DURING_TX;
-
-	if (ioctl (fd, TIOCSRS485, &rs485conf) < 0) {
-		/* Error handling. See errno. */
-	}
-
-	/* Use read() and write() syscalls here... */
-
-	/* Close the device when finished: */
-	if (close (fd) < 0) {
-		/* Error handling. See errno. */
-	}

+=================
+The Lockronomicon
+=================
+
+Your guide to the ancient and twisted locking policies of the tty layer and
+the warped logic behind them. Beware all ye who read on.
+
+
+Line Discipline
+---------------
+
+Line disciplines are registered with tty_register_ldisc() passing the
+discipline number and the ldisc structure. At the point of registration the
+discipline must be ready to use and it is possible it will get used before
+the call returns success. If the call returns an error then it won't get
+called. Do not re-use ldisc numbers as they are part of the userspace ABI
+and writing over an existing ldisc will cause demons to eat your computer.
+After the return the ldisc data has been copied so you may free your own
+copy of the structure. You must not re-register over the top of the line
+discipline even with the same data or your computer again will be eaten by
+demons.
+
+In order to remove a line discipline call tty_unregister_ldisc().
+In ancient times this always worked. In modern times the function will
+return -EBUSY if the ldisc is currently in use. Since the ldisc referencing
+code manages the module counts this should not usually be a concern.
+
+Heed this warning: the reference count field of the registered copies of the
+tty_ldisc structure in the ldisc table counts the number of lines using this
+discipline. The reference count of the tty_ldisc structure within a tty
+counts the number of active users of the ldisc at this instant. In effect it
+counts the number of threads of execution within an ldisc method (plus those
+about to enter and exit although this detail matters not).
+
+Line Discipline Methods
+-----------------------
+
+TTY side interfaces
+^^^^^^^^^^^^^^^^^^^
+
+======================= =======================================================
+open()			Called when the line discipline is attached to
+			the terminal. No other call into the line
+			discipline for this tty will occur until it
+			completes successfully. Should initialize any
+			state needed by the ldisc, and set receive_room
+			in the tty_struct to the maximum amount of data
+			the line discipline is willing to accept from the
+			driver with a single call to receive_buf().
+			Returning an error will prevent the ldisc from
+			being attached. Can sleep.
+
+close()			This is called on a terminal when the line
+			discipline is being unplugged. At the point of
+			execution no further users will enter the
+			ldisc code for this tty. Can sleep.
+
+hangup()		Called when the tty line is hung up.
+			The line discipline should cease I/O to the tty.
+			No further calls into the ldisc code will occur.
+			The return value is ignored. Can sleep.
+
+read()			(optional) A process requests reading data from
+			the line. Multiple read calls may occur in parallel
+			and the ldisc must deal with serialization issues.
+			If not defined, the process will receive an EIO
+			error. May sleep.
+
+write()			(optional) A process requests writing data to the
+			line. Multiple write calls are serialized by the
+			tty layer for the ldisc. If not defined, the
+			process will receive an EIO error. May sleep.
+
+flush_buffer()		(optional) May be called at any point between
+			open and close, and instructs the line discipline
+			to empty its input buffer.
+
+set_termios()		(optional) Called on termios structure changes.
+			The caller passes the old termios data and the
+			current data is in the tty. Called under the
+			termios semaphore so allowed to sleep. Serialized
+			against itself only.
+
+poll()			(optional) Check the status for the poll/select
+			calls. Multiple poll calls may occur in parallel.
+			May sleep.
+
+ioctl()			(optional) Called when an ioctl is handed to the
+			tty layer that might be for the ldisc. Multiple
+			ioctl calls may occur in parallel. May sleep.
+
+compat_ioctl()		(optional) Called when a 32 bit ioctl is handed
+			to the tty layer that might be for the ldisc.
+			Multiple ioctl calls may occur in parallel.
+			May sleep.
+======================= =======================================================
+
+Driver Side Interfaces
+^^^^^^^^^^^^^^^^^^^^^^
+
+======================= =======================================================
+receive_buf()		(optional) Called by the low-level driver to hand
+			a buffer of received bytes to the ldisc for
+			processing. The number of bytes is guaranteed not
+			to exceed the current value of tty->receive_room.
+			All bytes must be processed.
+
+receive_buf2()		(optional) Called by the low-level driver to hand
+			a buffer of received bytes to the ldisc for
+			processing. Returns the number of bytes processed.
+
+			If both receive_buf() and receive_buf2() are
+			defined, receive_buf2() should be preferred.
+
+write_wakeup()		May be called at any point between open and close.
+			The TTY_DO_WRITE_WAKEUP flag indicates if a call
+			is needed but always races versus calls. Thus the
+			ldisc must be careful about setting order and to
+			handle unexpected calls. Must not sleep.
+
+			The driver is forbidden from calling this directly
+			from the ->write call from the ldisc as the ldisc
+			is permitted to call the driver write method from
+			this function. In such a situation defer it.
+
+dcd_change()		Report to the tty line the current DCD pin status
+			changes and the relative timestamp. The timestamp
+			cannot be NULL.
+======================= =======================================================
+
+
+Driver Access
+^^^^^^^^^^^^^
+
+Line discipline methods can call the following methods of the underlying
+hardware driver through the function pointers within the tty->driver
+structure:
+
+======================= =======================================================
+write()			Write a block of characters to the tty device.
+			Returns the number of characters accepted. The
+			character buffer passed to this method is already
+			in kernel space.
+
+put_char()		Queues a character for writing to the tty device.
+			If there is no room in the queue, the character is
+			ignored.
+
+flush_chars()		(Optional) If defined, must be called after
+			queueing characters with put_char() in order to
+			start transmission.
+
+write_room()		Returns the numbers of characters the tty driver
+			will accept for queueing to be written.
+
+ioctl()			Invoke device specific ioctl.
+			Expects data pointers to refer to userspace.
+			Returns ENOIOCTLCMD for unrecognized ioctl numbers.
+
+set_termios()		Notify the tty driver that the device's termios
+			settings have changed. New settings are in
+			tty->termios. Previous settings should be passed in
+			the "old" argument.
+
+			The API is defined such that the driver should return
+			the actual modes selected. This means that the
+			driver function is responsible for modifying any
+			bits in the request it cannot fulfill to indicate
+			the actual modes being used. A device with no
+			hardware capability for change (e.g. a USB dongle or
+			virtual port) can provide NULL for this method.
+
+throttle()		Notify the tty driver that input buffers for the
+			line discipline are close to full, and it should
+			somehow signal that no more characters should be
+			sent to the tty.
+
+unthrottle()		Notify the tty driver that characters can now be
+			sent to the tty without fear of overrunning the
+			input buffers of the line disciplines.
+
+stop()			Ask the tty driver to stop outputting characters
+			to the tty device.
+
+start()			Ask the tty driver to resume sending characters
+			to the tty device.
+
+hangup()		Ask the tty driver to hang up the tty device.
+
+break_ctl()		(Optional) Ask the tty driver to turn on or off
+			BREAK status on the RS-232 port.  If state is -1,
+			then the BREAK status should be turned on; if
+			state is 0, then BREAK should be turned off.
+			If this routine is not implemented, use ioctls
+			TIOCSBRK / TIOCCBRK instead.
+
+wait_until_sent()	Waits until the device has written out all of the
+			characters in its transmitter FIFO.
+
+send_xchar()		Send a high-priority XON/XOFF character to the device.
+======================= =======================================================
+
+
+Flags
+^^^^^
+
+Line discipline methods have access to tty->flags field containing the
+following interesting flags:
+
+======================= =======================================================
+TTY_THROTTLED		Driver input is throttled. The ldisc should call
+			tty->driver->unthrottle() in order to resume
+			reception when it is ready to process more data.
+
+TTY_DO_WRITE_WAKEUP	If set, causes the driver to call the ldisc's
+			write_wakeup() method in order to resume
+			transmission when it can accept more data
+			to transmit.
+
+TTY_IO_ERROR		If set, causes all subsequent userspace read/write
+			calls on the tty to fail, returning -EIO.
+
+TTY_OTHER_CLOSED	Device is a pty and the other side has closed.
+
+TTY_NO_WRITE_SPLIT	Prevent driver from splitting up writes into
+			smaller chunks.
+======================= =======================================================
+
+
+Locking
+^^^^^^^
+
+Callers to the line discipline functions from the tty layer are required to
+take line discipline locks. The same is true of calls from the driver side
+but not yet enforced.
+
+Three calls are now provided::
+
+	ldisc = tty_ldisc_ref(tty);
+
+takes a handle to the line discipline in the tty and returns it. If no ldisc
+is currently attached or the ldisc is being closed and re-opened at this
+point then NULL is returned. While this handle is held the ldisc will not
+change or go away::
+
+	tty_ldisc_deref(ldisc)
+
+Returns the ldisc reference and allows the ldisc to be closed. Returning the
+reference takes away your right to call the ldisc functions until you take
+a new reference::
+
+	ldisc = tty_ldisc_ref_wait(tty);
+
+Performs the same function as tty_ldisc_ref except that it will wait for an
+ldisc change to complete and then return a reference to the new ldisc.
+
+While these functions are slightly slower than the old code they should have
+minimal impact as most receive logic uses the flip buffers and they only
+need to take a reference when they push bits up through the driver.
+
+A caution: The ldisc->open(), ldisc->close() and driver->set_ldisc
+functions are called with the ldisc unavailable. Thus tty_ldisc_ref will
+fail in this situation if used within these functions. Ldisc and driver
+code calling its own functions must be careful in this case.
+
+
+Driver Interface
+----------------
+
+======================= =======================================================
+open()			Called when a device is opened. May sleep
+
+close()			Called when a device is closed. At the point of
+			return from this call the driver must make no
+			further ldisc calls of any kind. May sleep
+
+write()			Called to write bytes to the device. May not
+			sleep. May occur in parallel in special cases.
+			Because this includes panic paths drivers generally
+			shouldn't try and do clever locking here.
+
+put_char()		Stuff a single character onto the queue. The
+			driver is guaranteed following up calls to
+			flush_chars.
+
+flush_chars()		Ask the kernel to write put_char queue
+
+write_room()		Return the number of characters that can be stuffed
+			into the port buffers without overflow (or less).
+			The ldisc is responsible for being intelligent
+			about multi-threading of write_room/write calls
+
+ioctl()			Called when an ioctl may be for the driver
+
+set_termios()		Called on termios change, serialized against
+			itself by a semaphore. May sleep.
+
+set_ldisc()		Notifier for discipline change. At the point this
+			is done the discipline is not yet usable. Can now
+			sleep (I think)
+
+throttle()		Called by the ldisc to ask the driver to do flow
+			control.  Serialization including with unthrottle
+			is the job of the ldisc layer.
+
+unthrottle()		Called by the ldisc to ask the driver to stop flow
+			control.
+
+stop()			Ldisc notifier to the driver to stop output. As with
+			throttle the serializations with start() are down
+			to the ldisc layer.
+
+start()			Ldisc notifier to the driver to start output.
+
+hangup()		Ask the tty driver to cause a hangup initiated
+			from the host side. [Can sleep ??]
+
+break_ctl()		Send RS232 break. Can sleep. Can get called in
+			parallel, driver must serialize (for now), and
+			with write calls.
+
+wait_until_sent()	Wait for characters to exit the hardware queue
+			of the driver. Can sleep
+
+send_xchar()	  	Send XON/XOFF and if possible jump the queue with
+			it in order to get fast flow control responses.
+			Cannot sleep ??

-break_ctl()		(Optional) Ask the tty driver to turn on or off
-			BREAK status on the RS-232 port.  If state is -1,
-			then the BREAK status should be turned on; if
-			state is 0, then BREAK should be turned off.
-			If this routine is not implemented, use ioctls
-			TIOCSBRK / TIOCCBRK instead.
-
-wait_until_sent()	Waits until the device has written out all of the
-			characters in its transmitter FIFO.
-
-send_xchar()		Send a high-priority XON/XOFF character to the device.
-
-
-Flags
-
-Line discipline methods have access to tty->flags field containing the
-following interesting flags:
-
-TTY_THROTTLED		Driver input is throttled. The ldisc should call
-			tty->driver->unthrottle() in order to resume
-			reception when it is ready to process more data.
-
-TTY_DO_WRITE_WAKEUP	If set, causes the driver to call the ldisc's
-			write_wakeup() method in order to resume
-			transmission when it can accept more data
-			to transmit.
-
-TTY_IO_ERROR		If set, causes all subsequent userspace read/write
-			calls on the tty to fail, returning -EIO.
-
-TTY_OTHER_CLOSED	Device is a pty and the other side has closed.
-
-TTY_NO_WRITE_SPLIT	Prevent driver from splitting up writes into
-			smaller chunks.
-
-
-Locking
-
-Callers to the line discipline functions from the tty layer are required to
-take line discipline locks. The same is true of calls from the driver side
-but not yet enforced.
-
-Three calls are now provided
-
-	ldisc = tty_ldisc_ref(tty);
-
-takes a handle to the line discipline in the tty and returns it. If no ldisc
-is currently attached or the ldisc is being closed and re-opened at this
-point then NULL is returned. While this handle is held the ldisc will not
-change or go away.
-
-	tty_ldisc_deref(ldisc)
-
-Returns the ldisc reference and allows the ldisc to be closed. Returning the
-reference takes away your right to call the ldisc functions until you take
-a new reference.
-
-	ldisc = tty_ldisc_ref_wait(tty);
-
-Performs the same function as tty_ldisc_ref except that it will wait for an
-ldisc change to complete and then return a reference to the new ldisc. 
-
-While these functions are slightly slower than the old code they should have
-minimal impact as most receive logic uses the flip buffers and they only
-need to take a reference when they push bits up through the driver.
-
-A caution: The ldisc->open(), ldisc->close() and driver->set_ldisc 
-functions are called with the ldisc unavailable. Thus tty_ldisc_ref will
-fail in this situation if used within these functions. Ldisc and driver
-code calling its own functions must be careful in this case. 
-
-
-Driver Interface
-----------------
-
-open()		-	Called when a device is opened. May sleep
-
-close()		-	Called when a device is closed. At the point of
-			return from this call the driver must make no 
-			further ldisc calls of any kind. May sleep
-
-write()		-	Called to write bytes to the device. May not
-			sleep. May occur in parallel in special cases. 
-			Because this includes panic paths drivers generally
-			shouldn't try and do clever locking here.
-
-put_char()	-	Stuff a single character onto the queue. The
-			driver is guaranteed following up calls to
-			flush_chars.
-
-flush_chars()	-	Ask the kernel to write put_char queue
-
-write_room()	-	Return the number of characters that can be stuffed
-			into the port buffers without overflow (or less).
-			The ldisc is responsible for being intelligent
- 			about multi-threading of write_room/write calls
-
-ioctl()		-	Called when an ioctl may be for the driver
-
-set_termios()	-	Called on termios change, serialized against
-			itself by a semaphore. May sleep.
-
-set_ldisc()	-	Notifier for discipline change. At the point this 
-			is done the discipline is not yet usable. Can now
-			sleep (I think)
-
-throttle()	-	Called by the ldisc to ask the driver to do flow
-			control.  Serialization including with unthrottle
-			is the job of the ldisc layer.
-
-unthrottle()	-	Called by the ldisc to ask the driver to stop flow
-			control.
-
-stop()		-	Ldisc notifier to the driver to stop output. As with
-			throttle the serializations with start() are down
-			to the ldisc layer.
-
-start()		-	Ldisc notifier to the driver to start output.
-
-hangup()	-	Ask the tty driver to cause a hangup initiated
-			from the host side. [Can sleep ??]
-
-break_ctl()	-	Send RS232 break. Can sleep. Can get called in
-			parallel, driver must serialize (for now), and
-			with write calls.
-
-wait_until_sent() -	Wait for characters to exit the hardware queue
-			of the driver. Can sleep
-
-send_xchar()	  -	Send XON/XOFF and if possible jump the queue with
-			it in order to get fast flow control responses.
-			Cannot sleep ??

+================================
+Application Data Integrity (ADI)
+================================
+
+SPARC M7 processor adds the Application Data Integrity (ADI) feature.
+ADI allows a task to set version tags on any subset of its address
+space. Once ADI is enabled and version tags are set for ranges of
+address space of a task, the processor will compare the tag in pointers
+to memory in these ranges to the version set by the application
+previously. Access to memory is granted only if the tag in given pointer
+matches the tag set by the application. In case of mismatch, processor
+raises an exception.
+
+Following steps must be taken by a task to enable ADI fully:
+
+1. Set the user mode PSTATE.mcde bit. This acts as master switch for
+   the task's entire address space to enable/disable ADI for the task.
+
+2. Set TTE.mcd bit on any TLB entries that correspond to the range of
+   addresses ADI is being enabled on. MMU checks the version tag only
+   on the pages that have TTE.mcd bit set.
+
+3. Set the version tag for virtual addresses using stxa instruction
+   and one of the MCD specific ASIs. Each stxa instruction sets the
+   given tag for one ADI block size number of bytes. This step must
+   be repeated for entire page to set tags for entire page.
+
+ADI block size for the platform is provided by the hypervisor to kernel
+in machine description tables. Hypervisor also provides the number of
+top bits in the virtual address that specify the version tag.  Once
+version tag has been set for a memory location, the tag is stored in the
+physical memory and the same tag must be present in the ADI version tag
+bits of the virtual address being presented to the MMU. For example on
+SPARC M7 processor, MMU uses bits 63-60 for version tags and ADI block
+size is same as cacheline size which is 64 bytes. A task that sets ADI
+version to, say 10, on a range of memory, must access that memory using
+virtual addresses that contain 0xa in bits 63-60.
+
+ADI is enabled on a set of pages using mprotect() with PROT_ADI flag.
+When ADI is enabled on a set of pages by a task for the first time,
+kernel sets the PSTATE.mcde bit fot the task. Version tags for memory
+addresses are set with an stxa instruction on the addresses using
+ASI_MCD_PRIMARY or ASI_MCD_ST_BLKINIT_PRIMARY. ADI block size is
+provided by the hypervisor to the kernel.  Kernel returns the value of
+ADI block size to userspace using auxiliary vector along with other ADI
+info. Following auxiliary vectors are provided by the kernel:
+
+	============	===========================================
+	AT_ADI_BLKSZ	ADI block size. This is the granularity and
+			alignment, in bytes, of ADI versioning.
+	AT_ADI_NBITS	Number of ADI version bits in the VA
+	============	===========================================
+
+
+IMPORTANT NOTES
+===============
+
+- Version tag values of 0x0 and 0xf are reserved. These values match any
+  tag in virtual address and never generate a mismatch exception.
+
+- Version tags are set on virtual addresses from userspace even though
+  tags are stored in physical memory. Tags are set on a physical page
+  after it has been allocated to a task and a pte has been created for
+  it.
+
+- When a task frees a memory page it had set version tags on, the page
+  goes back to free page pool. When this page is re-allocated to a task,
+  kernel clears the page using block initialization ASI which clears the
+  version tags as well for the page. If a page allocated to a task is
+  freed and allocated back to the same task, old version tags set by the
+  task on that page will no longer be present.
+
+- ADI tag mismatches are not detected for non-faulting loads.
+
+- Kernel does not set any tags for user pages and it is entirely a
+  task's responsibility to set any version tags. Kernel does ensure the
+  version tags are preserved if a page is swapped out to the disk and
+  swapped back in. It also preserves that version tags if a page is
+  migrated.
+
+- ADI works for any size pages. A userspace task need not be aware of
+  page size when using ADI. It can simply select a virtual address
+  range, enable ADI on the range using mprotect() and set version tags
+  for the entire range. mprotect() ensures range is aligned to page size
+  and is a multiple of page size.
+
+- ADI tags can only be set on writable memory. For example, ADI tags can
+  not be set on read-only mappings.

+
+ADI related traps
+=================
+
+With ADI enabled, following new traps may occur:
+
+Disrupting memory corruption
+----------------------------
+
+	When a store accesses a memory localtion that has TTE.mcd=1,
+	the task is running with ADI enabled (PSTATE.mcde=1), and the ADI
+	tag in the address used (bits 63:60) does not match the tag set on
+	the corresponding cacheline, a memory corruption trap occurs. By
+	default, it is a disrupting trap and is sent to the hypervisor
+	first. Hypervisor creates a sun4v error report and sends a
+	resumable error (TT=0x7e) trap to the kernel. The kernel sends
+	a SIGSEGV to the task that resulted in this trap with the following
+	info::
+
+		siginfo.si_signo = SIGSEGV;
+		siginfo.errno = 0;
+		siginfo.si_code = SEGV_ADIDERR;
+		siginfo.si_addr = addr; /* PC where first mismatch occurred */
+		siginfo.si_trapno = 0;
+
+
+Precise memory corruption
+-------------------------
+
+	When a store accesses a memory location that has TTE.mcd=1,
+	the task is running with ADI enabled (PSTATE.mcde=1), and the ADI
+	tag in the address used (bits 63:60) does not match the tag set on
+	the corresponding cacheline, a memory corruption trap occurs. If
+	MCD precise exception is enabled (MCDPERR=1), a precise
+	exception is sent to the kernel with TT=0x1a. The kernel sends
+	a SIGSEGV to the task that resulted in this trap with the following
+	info::
+
+		siginfo.si_signo = SIGSEGV;
+		siginfo.errno = 0;
+		siginfo.si_code = SEGV_ADIPERR;
+		siginfo.si_addr = addr;	/* address that caused trap */
+		siginfo.si_trapno = 0;
+
+	NOTE:
+		ADI tag mismatch on a load always results in precise trap.
+
+
+MCD disabled
+------------
+
+	When a task has not enabled ADI and attempts to set ADI version
+	on a memory address, processor sends an MCD disabled trap. This
+	trap is handled by hypervisor first and the hypervisor vectors this
+	trap through to the kernel as Data Access Exception trap with
+	fault type set to 0xa (invalid ASI). When this occurs, the kernel
+	sends the task SIGSEGV signal with following info::
+
+		siginfo.si_signo = SIGSEGV;
+		siginfo.errno = 0;
+		siginfo.si_code = SEGV_ACCADI;
+		siginfo.si_addr = addr;	/* address that caused trap */
+		siginfo.si_trapno = 0;

-Precise memory corruption
-
-	When a store accesses a memory location that has TTE.mcd=1,
-	the task is running with ADI enabled (PSTATE.mcde=1), and the ADI
-	tag in the address used (bits 63:60) does not match the tag set on
-	the corresponding cacheline, a memory corruption trap occurs. If
-	MCD precise exception is enabled (MCDPERR=1), a precise
-	exception is sent to the kernel with TT=0x1a. The kernel sends
-	a SIGSEGV to the task that resulted in this trap with the following
-	info:
-
-		siginfo.si_signo = SIGSEGV;
-		siginfo.errno = 0;
-		siginfo.si_code = SEGV_ADIPERR;
-		siginfo.si_addr = addr;	/* address that caused trap */
-		siginfo.si_trapno = 0;
-
-	NOTE: ADI tag mismatch on a load always results in precise trap.
-
-
-MCD disabled
-
-	When a task has not enabled ADI and attempts to set ADI version
-	on a memory address, processor sends an MCD disabled trap. This
-	trap is handled by hypervisor first and the hypervisor vectors this
-	trap through to the kernel as Data Access Exception trap with
-	fault type set to 0xa (invalid ASI). When this occurs, the kernel
-	sends the task SIGSEGV signal with following info:
-
-		siginfo.si_signo = SIGSEGV;
-		siginfo.errno = 0;
-		siginfo.si_code = SEGV_ACCADI;
-		siginfo.si_addr = addr;	/* address that caused trap */
-		siginfo.si_trapno = 0;

+=======================================
+Oracle Data Analytics Accelerator (DAX)
+=======================================
+
+DAX is a coprocessor which resides on the SPARC M7 (DAX1) and M8
+(DAX2) processor chips, and has direct access to the CPU's L3 caches
+as well as physical memory. It can perform several operations on data
+streams with various input and output formats.  A driver provides a
+transport mechanism and has limited knowledge of the various opcodes
+and data formats. A user space library provides high level services
+and translates these into low level commands which are then passed
+into the driver and subsequently the Hypervisor and the coprocessor.
+The library is the recommended way for applications to use the
+coprocessor, and the driver interface is not intended for general use.
+This document describes the general flow of the driver, its
+structures, and its programmatic interface. It also provides example
+code sufficient to write user or kernel applications that use DAX
+functionality.
+
+The user library is open source and available at:
+
+    https://oss.oracle.com/git/gitweb.cgi?p=libdax.git
+
+The Hypervisor interface to the coprocessor is described in detail in
+the accompanying document, dax-hv-api.txt, which is a plain text
+excerpt of the (Oracle internal) "UltraSPARC Virtual Machine
+Specification" version 3.0.20+15, dated 2017-09-25.
+
+
+High Level Overview
+===================
+
+A coprocessor request is described by a Command Control Block
+(CCB). The CCB contains an opcode and various parameters. The opcode
+specifies what operation is to be done, and the parameters specify
+options, flags, sizes, and addresses.  The CCB (or an array of CCBs)
+is passed to the Hypervisor, which handles queueing and scheduling of
+requests to the available coprocessor execution units. A status code
+returned indicates if the request was submitted successfully or if
+there was an error.  One of the addresses given in each CCB is a
+pointer to a "completion area", which is a 128 byte memory block that
+is written by the coprocessor to provide execution status. No
+interrupt is generated upon completion; the completion area must be
+polled by software to find out when a transaction has finished, but
+the M7 and later processors provide a mechanism to pause the virtual
+processor until the completion status has been updated by the
+coprocessor. This is done using the monitored load and mwait
+instructions, which are described in more detail later.  The DAX
+coprocessor was designed so that after a request is submitted, the
+kernel is no longer involved in the processing of it.  The polling is
+done at the user level, which results in almost zero latency between
+completion of a request and resumption of execution of the requesting
+thread.
+
+
+Addressing Memory
+=================
+
+The kernel does not have access to physical memory in the Sun4v
+architecture, as there is an additional level of memory virtualization
+present. This intermediate level is called "real" memory, and the
+kernel treats this as if it were physical.  The Hypervisor handles the
+translations between real memory and physical so that each logical
+domain (LDOM) can have a partition of physical memory that is isolated
+from that of other LDOMs.  When the kernel sets up a virtual mapping,
+it specifies a virtual address and the real address to which it should
+be mapped.
+
+The DAX coprocessor can only operate on physical memory, so before a
+request can be fed to the coprocessor, all the addresses in a CCB must
+be converted into physical addresses. The kernel cannot do this since
+it has no visibility into physical addresses. So a CCB may contain
+either the virtual or real addresses of the buffers or a combination
+of them. An "address type" field is available for each address that
+may be given in the CCB. In all cases, the Hypervisor will translate
+all the addresses to physical before dispatching to hardware. Address
+translations are performed using the context of the process initiating
+the request.
+
+
+The Driver API
+==============
+
+An application makes requests to the driver via the write() system
+call, and gets results (if any) via read(). The completion areas are
+made accessible via mmap(), and are read-only for the application.
+
+The request may either be an immediate command or an array of CCBs to
+be submitted to the hardware.
+
+Each open instance of the device is exclusive to the thread that
+opened it, and must be used by that thread for all subsequent
+operations. The driver open function creates a new context for the
+thread and initializes it for use.  This context contains pointers and
+values used internally by the driver to keep track of submitted
+requests. The completion area buffer is also allocated, and this is
+large enough to contain the completion areas for many concurrent
+requests.  When the device is closed, any outstanding transactions are
+flushed and the context is cleaned up.
+
+On a DAX1 system (M7), the device will be called "oradax1", while on a
+DAX2 system (M8) it will be "oradax2". If an application requires one
+or the other, it should simply attempt to open the appropriate
+device. Only one of the devices will exist on any given system, so the
+name can be used to determine what the platform supports.
+
+The immediate commands are CCB_DEQUEUE, CCB_KILL, and CCB_INFO. For
+all of these, success is indicated by a return value from write()
+equal to the number of bytes given in the call. Otherwise -1 is
+returned and errno is set.
+
+CCB_DEQUEUE
+-----------
+
+Tells the driver to clean up resources associated with past
+requests. Since no interrupt is generated upon the completion of a
+request, the driver must be told when it may reclaim resources.  No
+further status information is returned, so the user should not
+subsequently call read().
+
+CCB_KILL
+--------
+
+Kills a CCB during execution. The CCB is guaranteed to not continue
+executing once this call returns successfully. On success, read() must
+be called to retrieve the result of the action.
+
+CCB_INFO
+--------
+
+Retrieves information about a currently executing CCB. Note that some
+Hypervisors might return 'notfound' when the CCB is in 'inprogress'
+state. To ensure a CCB in the 'notfound' state will never be executed,
+CCB_KILL must be invoked on that CCB. Upon success, read() must be
+called to retrieve the details of the action.
+
+Submission of an array of CCBs for execution
+---------------------------------------------
+
+A write() whose length is a multiple of the CCB size is treated as a
+submit operation. The file offset is treated as the index of the
+completion area to use, and may be set via lseek() or using the
+pwrite() system call. If -1 is returned then errno is set to indicate
+the error. Otherwise, the return value is the length of the array that
+was actually accepted by the coprocessor. If the accepted length is
+equal to the requested length, then the submission was completely
+successful and there is no further status needed; hence, the user
+should not subsequently call read(). Partial acceptance of the CCB
+array is indicated by a return value less than the requested length,
+and read() must be called to retrieve further status information.  The
+status will reflect the error caused by the first CCB that was not
+accepted, and status_data will provide additional data in some cases.
+
+MMAP
+----
+
+The mmap() function provides access to the completion area allocated
+in the driver.  Note that the completion area is not writeable by the
+user process, and the mmap call must not specify PROT_WRITE.
+
+
+Completion of a Request
+=======================
+
+The first byte in each completion area is the command status which is
+updated by the coprocessor hardware. Software may take advantage of
+new M7/M8 processor capabilities to efficiently poll this status byte.
+First, a "monitored load" is achieved via a Load from Alternate Space
+(ldxa, lduba, etc.) with ASI 0x84 (ASI_MONITOR_PRIMARY).  Second, a
+"monitored wait" is achieved via the mwait instruction (a write to
+%asr28). This instruction is like pause in that it suspends execution
+of the virtual processor for the given number of nanoseconds, but in
+addition will terminate early when one of several events occur. If the
+block of data containing the monitored location is modified, then the
+mwait terminates. This causes software to resume execution immediately
+(without a context switch or kernel to user transition) after a
+transaction completes. Thus the latency between transaction completion
+and resumption of execution may be just a few nanoseconds.
+
+
+Application Life Cycle of a DAX Submission
+==========================================
+
+ - open dax device
+ - call mmap() to get the completion area address
+ - allocate a CCB and fill in the opcode, flags, parameters, addresses, etc.
+ - submit CCB via write() or pwrite()
+ - go into a loop executing monitored load + monitored wait and
+   terminate when the command status indicates the request is complete
+   (CCB_KILL or CCB_INFO may be used any time as necessary)
+ - perform a CCB_DEQUEUE
+ - call munmap() for completion area
+ - close the dax device
+
+
+Memory Constraints
+==================
+
+The DAX hardware operates only on physical addresses. Therefore, it is
+not aware of virtual memory mappings and the discontiguities that may
+exist in the physical memory that a virtual buffer maps to. There is
+no I/O TLB or any scatter/gather mechanism. All buffers, whether input
+or output, must reside in a physically contiguous region of memory.
+
+The Hypervisor translates all addresses within a CCB to physical
+before handing off the CCB to DAX. The Hypervisor determines the
+virtual page size for each virtual address given, and uses this to
+program a size limit for each address. This prevents the coprocessor
+from reading or writing beyond the bound of the virtual page, even
+though it is accessing physical memory directly. A simpler way of
+saying this is that a DAX operation will never "cross" a virtual page
+boundary. If an 8k virtual page is used, then the data is strictly
+limited to 8k. If a user's buffer is larger than 8k, then a larger
+page size must be used, or the transaction size will be truncated to
+8k.
+
+Huge pages. A user may allocate huge pages using standard interfaces.
+Memory buffers residing on huge pages may be used to achieve much
+larger DAX transaction sizes, but the rules must still be followed,
+and no transaction will cross a page boundary, even a huge page.  A
+major caveat is that Linux on Sparc presents 8Mb as one of the huge
+page sizes. Sparc does not actually provide a 8Mb hardware page size,
+and this size is synthesized by pasting together two 4Mb pages. The
+reasons for this are historical, and it creates an issue because only
+half of this 8Mb page can actually be used for any given buffer in a
+DAX request, and it must be either the first half or the second half;
+it cannot be a 4Mb chunk in the middle, since that crosses a
+(hardware) page boundary. Note that this entire issue may be hidden by
+higher level libraries.
+
+
+CCB Structure
+-------------
+A CCB is an array of 8 64-bit words. Several of these words provide
+command opcodes, parameters, flags, etc., and the rest are addresses
+for the completion area, output buffer, and various inputs::
+
+   struct ccb {
+       u64   control;
+       u64   completion;
+       u64   input0;
+       u64   access;
+       u64   input1;
+       u64   op_data;
+       u64   output;
+       u64   table;
+   };
+
+See libdax/common/sys/dax1/dax1_ccb.h for a detailed description of
+each of these fields, and see dax-hv-api.txt for a complete description
+of the Hypervisor API available to the guest OS (ie, Linux kernel).
+
+The first word (control) is examined by the driver for the following:
+ - CCB version, which must be consistent with hardware version
+ - Opcode, which must be one of the documented allowable commands
+ - Address types, which must be set to "virtual" for all the addresses
+   given by the user, thereby ensuring that the application can
+   only access memory that it owns
+
+
+Example Code
+============
+
+The DAX is accessible to both user and kernel code.  The kernel code
+can make hypercalls directly while the user code must use wrappers
+provided by the driver. The setup of the CCB is nearly identical for
+both; the only difference is in preparation of the completion area. An
+example of user code is given now, with kernel code afterwards.
+
+In order to program using the driver API, the file
+arch/sparc/include/uapi/asm/oradax.h must be included.
+
+First, the proper device must be opened. For M7 it will be
+/dev/oradax1 and for M8 it will be /dev/oradax2. The simplest
+procedure is to attempt to open both, as only one will succeed::
+
+	fd = open("/dev/oradax1", O_RDWR);
+	if (fd < 0)
+		fd = open("/dev/oradax2", O_RDWR);
+	if (fd < 0)
+	       /* No DAX found */
+
+Next, the completion area must be mapped::
+
+      completion_area = mmap(NULL, DAX_MMAP_LEN, PROT_READ, MAP_SHARED, fd, 0);
+
+All input and output buffers must be fully contained in one hardware
+page, since as explained above, the DAX is strictly constrained by
+virtual page boundaries.  In addition, the output buffer must be
+64-byte aligned and its size must be a multiple of 64 bytes because
+the coprocessor writes in units of cache lines.
+
+This example demonstrates the DAX Scan command, which takes as input a
+vector and a match value, and produces a bitmap as the output. For
+each input element that matches the value, the corresponding bit is
+set in the output.
+
+In this example, the input vector consists of a series of single bits,
+and the match value is 0. So each 0 bit in the input will produce a 1
+in the output, and vice versa, which produces an output bitmap which
+is the input bitmap inverted.
+
+For details of all the parameters and bits used in this CCB, please
+refer to section 36.2.1.3 of the DAX Hypervisor API document, which
+describes the Scan command in detail::
+
+	ccb->control =       /* Table 36.1, CCB Header Format */
+		  (2L << 48)     /* command = Scan Value */
+		| (3L << 40)     /* output address type = primary virtual */
+		| (3L << 34)     /* primary input address type = primary virtual */
+		             /* Section 36.2.1, Query CCB Command Formats */
+		| (1 << 28)     /* 36.2.1.1.1 primary input format = fixed width bit packed */
+		| (0 << 23)     /* 36.2.1.1.2 primary input element size = 0 (1 bit) */
+		| (8 << 10)     /* 36.2.1.1.6 output format = bit vector */
+		| (0 <<  5)	/* 36.2.1.3 First scan criteria size = 0 (1 byte) */
+		| (31 << 0);	/* 36.2.1.3 Disable second scan criteria */
+
+	ccb->completion = 0;    /* Completion area address, to be filled in by driver */
+
+	ccb->input0 = (unsigned long) input; /* primary input address */
+
+	ccb->access =       /* Section 36.2.1.2, Data Access Control */
+		  (2 << 24)    /* Primary input length format = bits */
+		| (nbits - 1); /* number of bits in primary input stream, minus 1 */
+
+	ccb->input1 = 0;       /* secondary input address, unused */
+
+	ccb->op_data = 0;      /* scan criteria (value to be matched) */
+
+	ccb->output = (unsigned long) output;	/* output address */
+
+	ccb->table = 0;	       /* table address, unused */
+
+The CCB submission is a write() or pwrite() system call to the
+driver. If the call fails, then a read() must be used to retrieve the
+status::
+
+	if (pwrite(fd, ccb, 64, 0) != 64) {
+		struct ccb_exec_result status;
+		read(fd, &status, sizeof(status));
+		/* bail out */
+	}
+
+After a successful submission of the CCB, the completion area may be

+
+	while (1) {
+		/* Monitored Load */
+		__asm__ __volatile__("lduba [%1] 0x84, %0\n"

+		/* MWAIT */

+	}
+
+A completion area status of 1 indicates successful completion of the
+CCB and validity of the output bitmap, which may be used immediately.
+All other non-zero values indicate error conditions which are
+described in section 36.2.2::

+		/* completion_area[0] contains the completion status */
+		/* completion_area[1] contains an error code, see 36.2.2 */
+	}
+
+After the completion area has been processed, the driver must be
+notified that it can release any resources associated with the
+request. This is done via the dequeue operation::
+
+	struct dax_command cmd;
+	cmd.command = CCB_DEQUEUE;
+	if (write(fd, &cmd, sizeof(cmd)) != sizeof(cmd)) {
+		/* bail out */
+	}
+
+Finally, normal program cleanup should be done, i.e., unmapping
+completion area, closing the dax device, freeing memory etc.
+
+Kernel example
+--------------
+
+The only difference in using the DAX in kernel code is the treatment
+of the completion area. Unlike user applications which mmap the
+completion area allocated by the driver, kernel code must allocate its
+own memory to use for the completion area, and this address and its
+type must be given in the CCB::
+
+	ccb->control |=      /* Table 36.1, CCB Header Format */
+	        (3L << 32);     /* completion area address type = primary virtual */
+
+	ccb->completion = (unsigned long) completion_area;   /* Completion area address */
+
+The dax submit hypercall is made directly. The flags used in the
+ccb_submit call are documented in the DAX HV API in section 36.3.1/
+
+::
+
+  #include <asm/hypervisor.h>
+
+	hv_rv = sun4v_ccb_submit((unsigned long)ccb, 64,

+

+		/* hv_rv is an error code, status_data contains */
+		/* potential additional status, see 36.3.1.1 */
+	}
+
+After the submission, the completion area polling code is identical to

-Oracle Data Analytics Accelerator (DAX)
----------------------------------------
-
-DAX is a coprocessor which resides on the SPARC M7 (DAX1) and M8
-(DAX2) processor chips, and has direct access to the CPU's L3 caches
-as well as physical memory. It can perform several operations on data
-streams with various input and output formats.  A driver provides a
-transport mechanism and has limited knowledge of the various opcodes
-and data formats. A user space library provides high level services
-and translates these into low level commands which are then passed
-into the driver and subsequently the Hypervisor and the coprocessor.
-The library is the recommended way for applications to use the
-coprocessor, and the driver interface is not intended for general use.
-This document describes the general flow of the driver, its
-structures, and its programmatic interface. It also provides example
-code sufficient to write user or kernel applications that use DAX
-functionality.
-
-The user library is open source and available at:
-    https://oss.oracle.com/git/gitweb.cgi?p=libdax.git
-
-The Hypervisor interface to the coprocessor is described in detail in
-the accompanying document, dax-hv-api.txt, which is a plain text
-excerpt of the (Oracle internal) "UltraSPARC Virtual Machine
-Specification" version 3.0.20+15, dated 2017-09-25.
-
-
-High Level Overview
--------------------
-
-A coprocessor request is described by a Command Control Block
-(CCB). The CCB contains an opcode and various parameters. The opcode
-specifies what operation is to be done, and the parameters specify
-options, flags, sizes, and addresses.  The CCB (or an array of CCBs)
-is passed to the Hypervisor, which handles queueing and scheduling of
-requests to the available coprocessor execution units. A status code
-returned indicates if the request was submitted successfully or if
-there was an error.  One of the addresses given in each CCB is a
-pointer to a "completion area", which is a 128 byte memory block that
-is written by the coprocessor to provide execution status. No
-interrupt is generated upon completion; the completion area must be
-polled by software to find out when a transaction has finished, but
-the M7 and later processors provide a mechanism to pause the virtual
-processor until the completion status has been updated by the
-coprocessor. This is done using the monitored load and mwait
-instructions, which are described in more detail later.  The DAX
-coprocessor was designed so that after a request is submitted, the
-kernel is no longer involved in the processing of it.  The polling is
-done at the user level, which results in almost zero latency between
-completion of a request and resumption of execution of the requesting
-thread.
-
-
-Addressing Memory
------------------
-
-The kernel does not have access to physical memory in the Sun4v
-architecture, as there is an additional level of memory virtualization
-present. This intermediate level is called "real" memory, and the
-kernel treats this as if it were physical.  The Hypervisor handles the
-translations between real memory and physical so that each logical
-domain (LDOM) can have a partition of physical memory that is isolated
-from that of other LDOMs.  When the kernel sets up a virtual mapping,
-it specifies a virtual address and the real address to which it should
-be mapped.
-
-The DAX coprocessor can only operate on physical memory, so before a
-request can be fed to the coprocessor, all the addresses in a CCB must
-be converted into physical addresses. The kernel cannot do this since
-it has no visibility into physical addresses. So a CCB may contain
-either the virtual or real addresses of the buffers or a combination
-of them. An "address type" field is available for each address that
-may be given in the CCB. In all cases, the Hypervisor will translate
-all the addresses to physical before dispatching to hardware. Address
-translations are performed using the context of the process initiating
-the request.
-
-
-The Driver API
---------------
-
-An application makes requests to the driver via the write() system
-call, and gets results (if any) via read(). The completion areas are
-made accessible via mmap(), and are read-only for the application.
-
-The request may either be an immediate command or an array of CCBs to
-be submitted to the hardware.
-
-Each open instance of the device is exclusive to the thread that
-opened it, and must be used by that thread for all subsequent
-operations. The driver open function creates a new context for the
-thread and initializes it for use.  This context contains pointers and
-values used internally by the driver to keep track of submitted
-requests. The completion area buffer is also allocated, and this is
-large enough to contain the completion areas for many concurrent
-requests.  When the device is closed, any outstanding transactions are
-flushed and the context is cleaned up.
-
-On a DAX1 system (M7), the device will be called "oradax1", while on a
-DAX2 system (M8) it will be "oradax2". If an application requires one
-or the other, it should simply attempt to open the appropriate
-device. Only one of the devices will exist on any given system, so the
-name can be used to determine what the platform supports.
-
-The immediate commands are CCB_DEQUEUE, CCB_KILL, and CCB_INFO. For
-all of these, success is indicated by a return value from write()
-equal to the number of bytes given in the call. Otherwise -1 is
-returned and errno is set.
-
-CCB_DEQUEUE
-
-Tells the driver to clean up resources associated with past
-requests. Since no interrupt is generated upon the completion of a
-request, the driver must be told when it may reclaim resources.  No
-further status information is returned, so the user should not
-subsequently call read().
-
-CCB_KILL
-
-Kills a CCB during execution. The CCB is guaranteed to not continue
-executing once this call returns successfully. On success, read() must
-be called to retrieve the result of the action.
-
-CCB_INFO
-
-Retrieves information about a currently executing CCB. Note that some
-Hypervisors might return 'notfound' when the CCB is in 'inprogress'
-state. To ensure a CCB in the 'notfound' state will never be executed,
-CCB_KILL must be invoked on that CCB. Upon success, read() must be
-called to retrieve the details of the action.
-
-Submission of an array of CCBs for execution
-
-A write() whose length is a multiple of the CCB size is treated as a
-submit operation. The file offset is treated as the index of the
-completion area to use, and may be set via lseek() or using the
-pwrite() system call. If -1 is returned then errno is set to indicate
-the error. Otherwise, the return value is the length of the array that
-was actually accepted by the coprocessor. If the accepted length is
-equal to the requested length, then the submission was completely
-successful and there is no further status needed; hence, the user
-should not subsequently call read(). Partial acceptance of the CCB
-array is indicated by a return value less than the requested length,
-and read() must be called to retrieve further status information.  The
-status will reflect the error caused by the first CCB that was not
-accepted, and status_data will provide additional data in some cases.
-
-MMAP
-
-The mmap() function provides access to the completion area allocated
-in the driver.  Note that the completion area is not writeable by the
-user process, and the mmap call must not specify PROT_WRITE.
-
-
-Completion of a Request
------------------------
-
-The first byte in each completion area is the command status which is
-updated by the coprocessor hardware. Software may take advantage of
-new M7/M8 processor capabilities to efficiently poll this status byte.
-First, a "monitored load" is achieved via a Load from Alternate Space
-(ldxa, lduba, etc.) with ASI 0x84 (ASI_MONITOR_PRIMARY).  Second, a
-"monitored wait" is achieved via the mwait instruction (a write to
-%asr28). This instruction is like pause in that it suspends execution
-of the virtual processor for the given number of nanoseconds, but in
-addition will terminate early when one of several events occur. If the
-block of data containing the monitored location is modified, then the
-mwait terminates. This causes software to resume execution immediately
-(without a context switch or kernel to user transition) after a
-transaction completes. Thus the latency between transaction completion
-and resumption of execution may be just a few nanoseconds.
-
-
-Application Life Cycle of a DAX Submission
-------------------------------------------
-
- - open dax device
- - call mmap() to get the completion area address
- - allocate a CCB and fill in the opcode, flags, parameters, addresses, etc.
- - submit CCB via write() or pwrite()
- - go into a loop executing monitored load + monitored wait and
-   terminate when the command status indicates the request is complete
-   (CCB_KILL or CCB_INFO may be used any time as necessary)
- - perform a CCB_DEQUEUE
- - call munmap() for completion area
- - close the dax device
-
-
-Memory Constraints
-------------------
-
-The DAX hardware operates only on physical addresses. Therefore, it is
-not aware of virtual memory mappings and the discontiguities that may
-exist in the physical memory that a virtual buffer maps to. There is
-no I/O TLB or any scatter/gather mechanism. All buffers, whether input
-or output, must reside in a physically contiguous region of memory.
-
-The Hypervisor translates all addresses within a CCB to physical
-before handing off the CCB to DAX. The Hypervisor determines the
-virtual page size for each virtual address given, and uses this to
-program a size limit for each address. This prevents the coprocessor
-from reading or writing beyond the bound of the virtual page, even
-though it is accessing physical memory directly. A simpler way of
-saying this is that a DAX operation will never "cross" a virtual page
-boundary. If an 8k virtual page is used, then the data is strictly
-limited to 8k. If a user's buffer is larger than 8k, then a larger
-page size must be used, or the transaction size will be truncated to
-8k.
-
-Huge pages. A user may allocate huge pages using standard interfaces.
-Memory buffers residing on huge pages may be used to achieve much
-larger DAX transaction sizes, but the rules must still be followed,
-and no transaction will cross a page boundary, even a huge page.  A
-major caveat is that Linux on Sparc presents 8Mb as one of the huge
-page sizes. Sparc does not actually provide a 8Mb hardware page size,
-and this size is synthesized by pasting together two 4Mb pages. The
-reasons for this are historical, and it creates an issue because only
-half of this 8Mb page can actually be used for any given buffer in a
-DAX request, and it must be either the first half or the second half;
-it cannot be a 4Mb chunk in the middle, since that crosses a
-(hardware) page boundary. Note that this entire issue may be hidden by
-higher level libraries.
-
-
-CCB Structure
--------------
-A CCB is an array of 8 64-bit words. Several of these words provide
-command opcodes, parameters, flags, etc., and the rest are addresses
-for the completion area, output buffer, and various inputs:
-
-   struct ccb {
-       u64   control;
-       u64   completion;
-       u64   input0;
-       u64   access;
-       u64   input1;
-       u64   op_data;
-       u64   output;
-       u64   table;
-   };
-
-See libdax/common/sys/dax1/dax1_ccb.h for a detailed description of
-each of these fields, and see dax-hv-api.txt for a complete description
-of the Hypervisor API available to the guest OS (ie, Linux kernel).
-
-The first word (control) is examined by the driver for the following:
- - CCB version, which must be consistent with hardware version
- - Opcode, which must be one of the documented allowable commands
- - Address types, which must be set to "virtual" for all the addresses
-   given by the user, thereby ensuring that the application can
-   only access memory that it owns
-
-
-Example Code
-------------
-
-The DAX is accessible to both user and kernel code.  The kernel code
-can make hypercalls directly while the user code must use wrappers
-provided by the driver. The setup of the CCB is nearly identical for
-both; the only difference is in preparation of the completion area. An
-example of user code is given now, with kernel code afterwards.
-
-In order to program using the driver API, the file
-arch/sparc/include/uapi/asm/oradax.h must be included.
-
-First, the proper device must be opened. For M7 it will be
-/dev/oradax1 and for M8 it will be /dev/oradax2. The simplest
-procedure is to attempt to open both, as only one will succeed:
-
-	fd = open("/dev/oradax1", O_RDWR);
-	if (fd < 0)
-		fd = open("/dev/oradax2", O_RDWR);
-	if (fd < 0)
-	       /* No DAX found */
-
-Next, the completion area must be mapped:
-
-      completion_area = mmap(NULL, DAX_MMAP_LEN, PROT_READ, MAP_SHARED, fd, 0);
-
-All input and output buffers must be fully contained in one hardware
-page, since as explained above, the DAX is strictly constrained by
-virtual page boundaries.  In addition, the output buffer must be
-64-byte aligned and its size must be a multiple of 64 bytes because
-the coprocessor writes in units of cache lines.
-
-This example demonstrates the DAX Scan command, which takes as input a
-vector and a match value, and produces a bitmap as the output. For
-each input element that matches the value, the corresponding bit is
-set in the output.
-
-In this example, the input vector consists of a series of single bits,
-and the match value is 0. So each 0 bit in the input will produce a 1
-in the output, and vice versa, which produces an output bitmap which
-is the input bitmap inverted.
-
-For details of all the parameters and bits used in this CCB, please
-refer to section 36.2.1.3 of the DAX Hypervisor API document, which
-describes the Scan command in detail.

-
-	ccb->output = (unsigned long) output;	/* output address */
-
-	ccb->table = 0;	       /* table address, unused */
-
-The CCB submission is a write() or pwrite() system call to the
-driver. If the call fails, then a read() must be used to retrieve the
-status:
-
-	if (pwrite(fd, ccb, 64, 0) != 64) {
-		struct ccb_exec_result status;
-		read(fd, &status, sizeof(status));
-		/* bail out */
-	}
-
-After a successful submission of the CCB, the completion area may be
-polled to determine when the DAX is finished. Detailed information on
-the contents of the completion area can be found in section 36.2.2 of
-the DAX HV API document.
-

-		/* completion_area[0] contains the completion status */
-		/* completion_area[1] contains an error code, see 36.2.2 */

-
-After the completion area has been processed, the driver must be

+Disclaimer
+----------
+
+Translation's purpose is to ease reading and understanding in languages other
+than English. Its aim is to help people who do not understand English or have
+doubts about its interpretation. Additionally, some people prefer to read
+documentation in their native language, but please bear in mind that the
+*only* official documentation is the English one: :ref:`linux_doc`.
+
+It is very unlikely that an update to :ref:`linux_doc` will be propagated
+immediately to all translations.  Translations' maintainers - and
+contributors - follow the evolution of the official documentation and they
+maintain translations aligned as much as they can.  For this reason there is
+no guarantee that a translation is up to date.  If what you read in a
+translation does not sound right compared to what you read in the code, please
+inform the translation maintainer and - if you can - check also the English
+documentation.
+
+A translation is not a fork of the official documentation, therefore
+translations' users should not find information that differs from the official
+English documentation.  Any content addition, removal or update, must be
+applied to the English documents first.  Afterwards and when possible, the
+same change should be applied to translations.  Translations' maintainers
+accept only contributions that are merely translation related (e.g. new
+translations, updates, fixes).
+
+Translations try to be as accurate as possible but it is not possible to map
+one language directly to all other languages. Each language has its own
+grammar and culture, so the translation of an English statement may need to be
+adapted to fit a different language.  For this reason, when viewing
+translations, you may find slight differences that carry the same message but
+in a different form.
+
+If you need to communicate with the Linux community but you do not feel
+comfortable writing in English, you can ask the translation's maintainers
+for help.

 L'obiettivo di questa traduzione è di rendere più facile la lettura e
-la comprensione per chi preferisce leggere in lingua italiana.
-Tenete presente che la documentazione di riferimento rimane comunque
-quella in lingua inglese: :ref:`linux_doc`
+la comprensione per chi non capisce l'inglese o ha dubbi sulla sua
+interpretazione, oppure semplicemente per chi preferisce leggere in lingua
+italiana. Tuttavia, tenete ben presente che l'*unica* documentazione
+ufficiale è quella in lingua inglese: :ref:`linux_doc`
 
-Questa traduzione cerca di essere il più fedele possibile all'originale ma
-è ovvio che alcune frasi vadano trasformate: non aspettatevi una traduzione
-letterale. Quando possibile, si eviteranno gli inglesismi ed al loro posto
-verranno utilizzate le corrispettive parole italiane.
+La propagazione simultanea a tutte le traduzioni di una modifica in
+:ref:`linux_doc` è altamente improbabile. I manutentori delle traduzioni -
+e i contributori - seguono l'evolversi della documentazione ufficiale e
+cercano di mantenere le rispettive traduzioni allineate nel limite del
+possibile.  Per questo motivo non c'è garanzia che una traduzione sia
+aggiornata all'ultima modifica.  Se quello che leggete in una traduzione
+non corrisponde a quello che leggete nel codice, informate il manutentore
+della traduzione e - se potete - verificate anche la documentazione in
+inglese.
 
-Se notate che la traduzione non è più aggiornata potete contattare
-direttamente il manutentore della traduzione italiana.
+Una traduzione non è un *fork* della documentazione ufficiale, perciò gli
+utenti non vi troveranno alcuna informazione diversa rispetto alla versione
+ufficiale.  Ogni aggiunta, rimozione o modifica dei contenuti deve essere
+fatta prima nei documenti in inglese. In seguito, e quando è possibile, la
+stessa modifica dovrebbe essere applicata anche alle traduzioni.  I manutentori
+delle traduzioni accettano contributi che interessano prettamente l'attività
+di traduzione (per esempio, nuove traduzioni, aggiornamenti, correzioni).
 
-Se notate che la documentazione contiene errori o dimenticanze, allora
-verificate la documentazione di riferimento in lingua inglese. Se il problema
-è presente anche nella documentazione di riferimento, contattate il suo
-manutentore. Se avete problemi a scrivere in inglese, potete comunque
-riportare il problema al manutentore della traduzione italiana.
+Le traduzioni cercano di essere il più possibile accurate ma non è possibile
+mappare direttamente una lingua in un'altra. Ogni lingua ha la sua grammatica
+e una sua cultura alle spalle, quindi la traduzione di una frase in inglese
+potrebbe essere modificata per adattarla all'italiano. Per questo motivo,
+quando leggete questa traduzione, potreste trovare alcune differenze di forma
+ma che trasmettono comunque il messaggio originale.  Nonostante la grande
+diffusione di inglesismi nella lingua parlata, quando possibile, questi
+verranno sostituiti dalle corrispettive parole italiane

+
+==============================================================================
+Interfacce deprecate, caratteristiche del linguaggio, attributi, e convenzioni
+==============================================================================
+
+In un mondo perfetto, sarebbe possibile prendere tutti gli usi di
+un'interfaccia deprecata e convertirli in quella nuova, e così sarebbe
+possibile rimuovere la vecchia interfaccia in un singolo ciclo di sviluppo.
+Tuttavia, per via delle dimensioni del kernel, la gerarchia dei manutentori e
+le tempistiche, non è sempre possibile fare questo tipo di conversione tutta
+in una volta. Questo significa che nuove istanze di una vecchia interfaccia
+potrebbero aggiungersi al kernel proprio quando si sta cercando di rimuoverle,
+aumentando così il carico di lavoro. Al fine di istruire gli sviluppatori su
+cosa è considerato deprecato (e perché), è stata create la seguente lista a cui
+fare riferimento quando qualcuno propone modifiche che usano cose deprecate.
+
+__deprecated
+------------
+Nonostante questo attributo marchi visibilmente un interfaccia come deprecata,
+`non produce più alcun avviso durante la compilazione
+<https://git.kernel.org/linus/771c035372a036f83353eef46dbb829780330234>`_
+perché uno degli obiettivi del kernel è quello di compilare senza avvisi;
+inoltre, nessuno stava agendo per rimuovere queste interfacce. Nonostante l'uso
+di `__deprecated` in un file d'intestazione sia opportuno per segnare una
+interfaccia come 'vecchia', questa non è una soluzione completa. L'interfaccia
+deve essere rimossa dal kernel, o aggiunta a questo documento per scoraggiarne
+l'uso.
+
+Calcoli codificati negli argomenti di un allocatore
+----------------------------------------------------
+Il calcolo dinamico delle dimensioni (specialmente le moltiplicazioni) non
+dovrebbero essere fatto negli argomenti di funzioni di allocazione di memoria
+(o simili) per via del rischio di overflow. Questo può portare a valori più
+piccoli di quelli che il chiamante si aspettava. L'uso di questo modo di
+allocare può portare ad un overflow della memoria di heap e altri
+malfunzionamenti. (Si fa eccezione per valori numerici per i quali il
+compilatore può generare avvisi circa un potenziale overflow. Tuttavia usare
+i valori numerici come suggerito di seguito è innocuo).
+
+Per esempio, non usate ``count * size`` come argomento::
+
+	foo = kmalloc(count * size, GFP_KERNEL);
+
+Al suo posto, si dovrebbe usare l'allocatore a due argomenti::
+
+	foo = kmalloc_array(count, size, GFP_KERNEL);
+
+Se questo tipo di allocatore non è disponibile, allora dovrebbero essere usate
+le funzioni del tipo *saturate-on-overflow*::
+
+	bar = vmalloc(array_size(count, size));
+
+Un altro tipico caso da evitare è quello di calcolare la dimensione di una
+struttura seguita da un vettore di altre strutture, come nel seguente caso::
+
+	header = kzalloc(sizeof(*header) + count * sizeof(*header->item),
+			 GFP_KERNEL);
+
+Invece, usate la seguente funzione::
+
+	header = kzalloc(struct_size(header, item, count), GFP_KERNEL);
+
+Per maggiori dettagli fate riferimento a :c:func:`array_size`,
+:c:func:`array3_size`, e :c:func:`struct_size`, così come la famiglia di
+funzioni :c:func:`check_add_overflow` e :c:func:`check_mul_overflow`.
+
+simple_strtol(), simple_strtoll(), simple_strtoul(), simple_strtoull()
+----------------------------------------------------------------------
+Le funzioni :c:func:`simple_strtol`, :c:func:`simple_strtoll`,
+:c:func:`simple_strtoul`, e :c:func:`simple_strtoull` ignorano volutamente
+i possibili overflow, e questo può portare il chiamante a generare risultati
+inaspettati. Le rispettive funzioni :c:func:`kstrtol`, :c:func:`kstrtoll`,
+:c:func:`kstrtoul`, e :c:func:`kstrtoull` sono da considerarsi le corrette
+sostitute; tuttavia va notato che queste richiedono che la stringa sia
+terminata con il carattere NUL o quello di nuova riga.
+
+strcpy()
+--------
+La funzione :c:func:`strcpy` non fa controlli agli estremi del buffer
+di destinazione. Questo può portare ad un overflow oltre i limiti del
+buffer e generare svariati tipi di malfunzionamenti. Nonostante l'opzione
+`CONFIG_FORTIFY_SOURCE=y` e svariate opzioni del compilatore aiutano
+a ridurne il rischio, non c'è alcuna buona ragione per continuare ad usare
+questa funzione. La versione sicura da usare è :c:func:`strscpy`.
+
+strncpy() su stringe terminate con NUL
+--------------------------------------
+L'utilizzo di :c:func:`strncpy` non fornisce alcuna garanzia sul fatto che
+il buffer di destinazione verrà terminato con il carattere NUL. Questo
+potrebbe portare a diversi overflow di lettura o altri malfunzionamenti
+causati, appunto, dalla mancanza del terminatore. Questa estende la
+terminazione nel buffer di destinazione quando la stringa d'origine è più
+corta; questo potrebbe portare ad una penalizzazione delle prestazioni per
+chi usa solo stringe terminate. La versione sicura da usare è
+:c:func:`strscpy`. (chi usa :c:func:`strscpy` e necessita di estendere la
+terminazione con NUL deve aggiungere una chiamata a :c:func:`memset`)
+
+Se il chiamate no usa stringhe terminate con NUL, allore :c:func:`strncpy()`
+può continuare ad essere usata, ma i buffer di destinazione devono essere
+marchiati con l'attributo `__nonstring <https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html>`_
+per evitare avvisi durante la compilazione.
+
+strlcpy()
+---------
+La funzione :c:func:`strlcpy`, per prima cosa, legge interamente il buffer di
+origine, magari leggendo più di quanto verrà effettivamente copiato. Questo
+è inefficiente e può portare a overflow di lettura quando la stringa non è
+terminata con NUL. La versione sicura da usare è :c:func:`strscpy`.
+
+Vettori a dimensione variabile (VLA)
+------------------------------------
+
+Usare VLA sullo stack produce codice molto peggiore rispetto a quando si usano
+vettori a dimensione fissa. Questi `problemi di prestazioni <https://git.kernel.org/linus/02361bc77888>`_,
+tutt'altro che banali, sono già un motivo valido per eliminare i VLA; in
+aggiunta sono anche un problema per la sicurezza. La crescita dinamica di un
+vettore nello stack potrebbe eccedere la memoria rimanente in tale segmento.
+Questo può portare a dei malfunzionamenti, potrebbe sovrascrivere
+dati importanti alla fine dello stack (quando il kernel è compilato senza
+`CONFIG_THREAD_INFO_IN_TASK=y`), o sovrascrivere un pezzo di memoria adiacente
+allo stack (quando il kernel è compilato senza `CONFIG_VMAP_STACK=y`).

+LICENSES/exceptions/Linux-syscall-note; tutto ciò è descritto nel file COPYING.
+
+Questo documento fornisce una descrizione su come ogni singolo file sorgente
+debba essere licenziato per far si che sia chiaro e non ambiguo. Questo non
+sostituisce la licenza del kernel.
+
+La licenza descritta nel file COPYING si applica ai sorgenti del kernel nella
+loro interezza, quindi i singoli file sorgenti possono avere diverse licenze ma
+devono essere compatibili con la GPL-2.0::
+
+    GPL-1.0+  :  GNU General Public License v1.0 o successiva
+    GPL-2.0+  :  GNU General Public License v2.0 o successiva
+    LGPL-2.0  :  GNU Library General Public License v2
+    LGPL-2.0+ :  GNU Library General Public License v2 o successiva
+    LGPL-2.1  :  GNU Lesser General Public License v2.1
+    LGPL-2.1+ :  GNU Lesser General Public License v2.1 o successiva
+
+A parte questo, i singolo file possono essere forniti con una doppia licenza,
+per esempio con una delle varianti compatibili della GPL e alternativamente con
+una licenza permissiva come BSD, MIT eccetera.
+
+I file d'intestazione per l'API verso lo spazio utente (UAPI) descrivono
+le interfacce usate dai programmi, e per questo sono un caso speciale.
+Secondo le note nel file COPYING, le chiamate di sistema sono un chiaro
+confine oltre il quale non si estendono i requisiti della GPL per quei
+programmi che le usano per comunicare con il kernel.  Dato che i file
+d'intestazione UAPI devono poter essere inclusi nei sorgenti di un
+qualsiasi programma eseguibile sul kernel Linux, questi meritano
+un'eccezione documentata da una clausola speciale.
+
+Il modo più comune per indicare la licenza dei file sorgenti è quello di
+aggiungere il corrispondente blocco di testo come commento in testa a detto
+file.  Per via della formattazione, dei refusi, eccetera, questi blocchi di
+testo sono difficili da identificare dagli strumenti usati per verificare il
+rispetto delle licenze.
+
+Un'alternativa ai blocchi di testo è data dall'uso degli identificatori
+*Software Package Data Exchange* (SPDX) in ogni file sorgente.  Gli
+identificatori di licenza SPDX sono analizzabili dalle macchine e sono precisi
+simboli stenografici che identificano la licenza sotto la quale viene
+licenziato il file che lo include.  Gli identificatori di licenza SPDX sono
+gestiti del gruppo di lavoro SPDX presso la Linux Foundation e sono stati
+concordati fra i soci nell'industria, gli sviluppatori di strumenti, e i
+rispettivi gruppi legali. Per maggiori informazioni, consultate
+https://spdx.org/
+
+Il kernel Linux richiede un preciso identificatore SPDX in tutti i file
+sorgenti.  Gli identificatori validi verranno spiegati nella sezione
+`Identificatori di licenza`_ e sono stati copiati dalla lista ufficiale di
+licenze SPDX assieme al rispettivo testo come mostrato in
+https://spdx.org/licenses/.
+
+Sintassi degli identificatori di licenza
+----------------------------------------
+
+1. Posizionamento:
+
+   L'identificativo di licenza SPDX dev'essere posizionato come prima riga
+   possibile di un file che possa contenere commenti.  Per la maggior parte
+   dei file questa è la prima riga, fanno eccezione gli script che richiedono
+   come prima riga '#!PATH_TO_INTERPRETER'.  Per questi script l'identificativo
+   SPDX finisce nella seconda riga.
+
+|
+
+2. Stile:
+
+   L'identificativo di licenza SPDX viene aggiunto sotto forma di commento.
+   Lo stile del commento dipende dal tipo di file::
+
+      sorgenti C:	// SPDX-License-Identifier: <SPDX License Expression>
+      intestazioni C:	/* SPDX-License-Identifier: <SPDX License Expression> */
+      ASM:	/* SPDX-License-Identifier: <SPDX License Expression> */
+      scripts:	# SPDX-License-Identifier: <SPDX License Expression>
+      .rst:	.. SPDX-License-Identifier: <SPDX License Expression>
+      .dts{i}:	// SPDX-License-Identifier: <SPDX License Expression>
+
+   Se un particolare programma non dovesse riuscire a gestire lo stile
+   principale per i commenti, allora dev'essere usato il meccanismo accettato
+   dal programma.  Questo è il motivo per cui si ha "/\* \*/" nei file
+   d'intestazione C.  Notammo che 'ld' falliva nell'analizzare i commenti del
+   C++ nei file .lds che venivano prodotti.  Oggi questo è stato corretto,
+   ma ci sono in giro ancora vecchi programmi che non sono in grado di
+   gestire lo stile dei commenti del C++.
+
+|
+
+3. Sintassi:
+
+   Una <espressione di licenza SPDX> può essere scritta usando l'identificatore
+   SPDX della licenza come indicato nella lista di licenze SPDX, oppure la
+   combinazione di due identificatori SPDX separati da "WITH" per i casi
+   eccezionali. Quando si usano più licenze l'espressione viene formata da
+   sottoespressioni separate dalle parole chiave "AND", "OR" e racchiuse fra
+   parentesi tonde "(", ")".
+
+   Gli identificativi di licenza per licenze come la [L]GPL che si avvalgono
+   dell'opzione 'o successive' si formano aggiungendo alla fine il simbolo "+"
+   per indicare l'opzione 'o successive'.::
+
+      // SPDX-License-Identifier: GPL-2.0+
+      // SPDX-License-Identifier: LGPL-2.1+
+
+   WITH dovrebbe essere usato quando sono necessarie delle modifiche alla
+   licenza.  Per esempio, la UAPI del kernel linux usa l'espressione::
+
+      // SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
+      // SPDX-License-Identifier: GPL-2.0+ WITH Linux-syscall-note
+
+   Altri esempi di usi di WITH all'interno del kernel sono::
+
+      // SPDX-License-Identifier: GPL-2.0 WITH mif-exception
+      // SPDX-License-Identifier: GPL-2.0+ WITH GCC-exception-2.0
+
+   Le eccezioni si possono usare solo in combinazione con identificatori di
+   licenza. Gli identificatori di licenza riconosciuti sono elencati nei
+   corrispondenti file d'eccezione. Per maggiori dettagli consultate
+   `Eccezioni`_ nel capitolo `Identificatori di licenza`_
+
+   La parola chiave OR dovrebbe essere usata solo quando si usa una doppia
+   licenza e solo una dev'essere scelta.  Per esempio, alcuni file dtsi sono
+   disponibili con doppia licenza::
+
+      // SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause
+
+   Esempi dal kernel di espressioni per file licenziati con doppia licenza
+   sono::
+
+      // SPDX-License-Identifier: GPL-2.0 OR MIT
+      // SPDX-License-Identifier: GPL-2.0 OR BSD-2-Clause
+      // SPDX-License-Identifier: GPL-2.0 OR Apache-2.0
+      // SPDX-License-Identifier: GPL-2.0 OR MPL-1.1
+      // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) OR MIT
+      // SPDX-License-Identifier: GPL-1.0+ OR BSD-3-Clause OR OpenSSL
+
+   La parola chiave AND dovrebbe essere usata quando i termini di più licenze
+   si applicano ad un file. Per esempio, quando il codice viene preso da
+   un altro progetto il quale da i permessi per aggiungerlo nel kernel ma
+   richiede che i termini originali della licenza rimangano intatti::
+
+      // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) AND MIT
+
+   Di seguito, un altro esempio dove entrambe i termini di licenza devono
+   essere rispettati::
+
+      // SPDX-License-Identifier: GPL-1.0+ AND LGPL-2.1+
+
+Identificatori di licenza
+-------------------------
+
+Le licenze attualmente in uso, così come le licenze aggiunte al kernel, possono
+essere categorizzate in:
+
+1. _`Licenze raccomandate`:
+
+   Ovunque possibile le licenze qui indicate dovrebbero essere usate perché
+   pienamente compatibili e molto usate.  Queste licenze sono disponibile nei
+   sorgenti del kernel, nella cartella::
+
+     LICENSES/preferred/
+
+   I file in questa cartella contengono il testo completo della licenza e i
+   `Metatag`_.  Il nome di questi file è lo stesso usato come identificatore
+   di licenza SPDX e che deve essere usato nei file sorgenti.
+
+   Esempi::
+
+     LICENSES/preferred/GPL-2.0
+
+   Contiene il testo della seconda versione della licenza GPL e i metatag
+   necessari::
+
+     LICENSES/preferred/MIT
+
+   Contiene il testo della licenza MIT e i metatag necessari.
+
+   _`Metatag`:
+
+   I seguenti metatag devono essere presenti in un file di licenza:
+
+   - Valid-License-Identifier:
+
+     Una o più righe che dichiarano quali identificatori di licenza sono validi
+     all'interno del progetto per far riferimento alla licenza in questione.
+     Solitamente, questo è un unico identificatore valido, ma per esempio le
+     licenze che permettono l'opzione 'o successive' hanno due identificatori
+     validi.
+
+   - SPDX-URL:
+
+     L'URL della pagina SPDX che contiene informazioni aggiuntive riguardanti
+     la licenza.
+
+   - Usage-Guidance:
+
+     Testo in formato libero per dare suggerimenti agli utenti. Il testo deve
+     includere degli esempi su come usare gli identificatori di licenza SPDX
+     in un file sorgente in conformità con le linea guida in
+     `Sintassi degli identificatori di licenza`_.
+
+   - License-Text:
+
+     Tutto il testo che compare dopo questa etichetta viene trattato
+     come se fosse parte del testo originale della licenza.
+
+   Esempi::
+
+      Valid-License-Identifier: GPL-2.0
+      Valid-License-Identifier: GPL-2.0+
+      SPDX-URL: https://spdx.org/licenses/GPL-2.0.html
+      Usage-Guide:
+        To use this license in source code, put one of the following SPDX
+	tag/value pairs into a comment according to the placement
+	guidelines in the licensing rules documentation.
+	For 'GNU General Public License (GPL) version 2 only' use:
+	  SPDX-License-Identifier: GPL-2.0
+	For 'GNU General Public License (GPL) version 2 or any later version' use:
+	  SPDX-License-Identifier: GPL-2.0+
+      License-Text:
+        Full license text
+
+   ::
+
+      SPDX-License-Identifier: MIT
+      SPDX-URL: https://spdx.org/licenses/MIT.html
+      Usage-Guide:
+	To use this license in source code, put the following SPDX
+	tag/value pair into a comment according to the placement
+	guidelines in the licensing rules documentation.
+	  SPDX-License-Identifier: MIT
+      License-Text:
+        Full license text
+
+|
+
+2. Licenze deprecate:
+
+   Questo tipo di licenze dovrebbero essere usate solo per codice già esistente
+   o quando si prende codice da altri progetti.  Le licenze sono disponibili
+   nei sorgenti del kernel nella cartella::
+
+     LICENSES/deprecated/
+
+   I file in questa cartella contengono il testo completo della licenza e i
+   `Metatag`_.  Il nome di questi file è lo stesso usato come identificatore
+   di licenza SPDX e che deve essere usato nei file sorgenti.
+
+   Esempi::
+
+     LICENSES/deprecated/ISC
+
+   Contiene il testo della licenza Internet System Consortium e i suoi
+   metatag::
+
+     LICENSES/deprecated/GPL-1.0
+
+   Contiene il testo della versione 1 della licenza GPL e i suoi metatag.
+
+   Metatag:
+
+   I metatag necessari per le 'altre' ('other') licenze sono gli stessi
+   di usati per le `Licenze raccomandate`_.
+
+   Esempio del formato del file::
+
+      Valid-License-Identifier: ISC
+      SPDX-URL: https://spdx.org/licenses/ISC.html
+      Usage-Guide:
+        Usage of this license in the kernel for new code is discouraged
+        and it should solely be used for importing code from an already
+        existing project.
+        To use this license in source code, put the following SPDX
+        tag/value pair into a comment according to the placement
+        guidelines in the licensing rules documentation.
+          SPDX-License-Identifier: ISC
+      License-Text:
+        Full license text
+
+|
+
+3. Solo per doppie licenze
+
+   Queste licenze dovrebbero essere usate solamente per codice licenziato in
+   combinazione con un'altra licenza che solitamente è quella preferita.
+   Queste licenze sono disponibili nei sorgenti del kernel nella cartella::
+
+     LICENSES/dual
+
+   I file in questa cartella contengono il testo completo della rispettiva
+   licenza e i suoi `Metatags`_.  I nomi dei file sono identici agli
+   identificatori di licenza SPDX che dovrebbero essere usati nei file
+   sorgenti.
+
+   Esempi::
+
+     LICENSES/dual/MPL-1.1
+
+   Questo file contiene il testo della versione 1.1 della licenza *Mozilla
+   Pulic License* e i metatag necessari::
+
+     LICENSES/dual/Apache-2.0
+
+   Questo file contiene il testo della versione 2.0 della licenza Apache e i
+   metatag necessari.
+
+   Metatag:
+
+   I requisiti per le 'altre' ('*other*') licenze sono identici a quelli per le
+   `Licenze raccomandate`_.
+
+   Esempio del formato del file::
+
+   Valid-License-Identifier: MPL-1.1
+   SPDX-URL: https://spdx.org/licenses/MPL-1.1.html
+   Usage-Guide:
+     Do NOT use. The MPL-1.1 is not GPL2 compatible. It may only be used for
+     dual-licensed files where the other license is GPL2 compatible.
+     If you end up using this it MUST be used together with a GPL2 compatible
+     license using "OR".
+     To use the Mozilla Public License version 1.1 put the following SPDX
+     tag/value pair into a comment according to the placement guidelines in
+     the licensing rules documentation:
+   SPDX-License-Identifier: MPL-1.1
+   License-Text:
+     Full license text
+
+|
+
+4. _`Eccezioni`:
+
+   Alcune licenze possono essere corrette con delle eccezioni che forniscono
+   diritti aggiuntivi.  Queste eccezioni sono disponibili nei sorgenti del
+   kernel nella cartella::
+
+     LICENSES/exceptions/
+
+   I file in questa cartella contengono il testo completo dell'eccezione e i
+   `Metatag per le eccezioni`_.
+
+   Esempi::
+
+      LICENSES/exceptions/Linux-syscall-note
+
+   Contiene la descrizione dell'eccezione per le chiamate di sistema Linux
+   così come documentato nel file COPYING del kernel Linux; questo viene usato
+   per i file d'intestazione per la UAPI.  Per esempio
+   /\* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note \*/::
+
+      LICENSES/exceptions/GCC-exception-2.0
+
+   Contiene la 'eccezione di linking' che permette di collegare qualsiasi
+   binario, indipendentemente dalla sua licenza, con un compilato il cui file
+   sorgente è marchiato con questa eccezione. Questo è necessario per creare
+   eseguibili dai sorgenti che non sono compatibili con la GPL.
+
+   _`Metatag per le eccezioni`:
+
+   Un file contenente un'eccezione deve avere i seguenti metatag:
+
+   - SPDX-Exception-Identifier:
+
+     Un identificatore d'eccezione che possa essere usato in combinazione con
+     un identificatore di licenza SPDX.
+
+   - SPDX-URL:
+
+     L'URL della pagina SPDX che contiene informazioni aggiuntive riguardanti
+     l'eccezione.
+
+   - SPDX-Licenses:
+
+     Una lista di licenze SPDX separate da virgola, che possono essere usate
+     con l'eccezione.
+
+   - Usage-Guidance:
+
+     Testo in formato libero per dare suggerimenti agli utenti. Il testo deve
+     includere degli esempi su come usare gli identificatori di licenza SPDX
+     in un file sorgente in conformità con le linea guida in
+     `Sintassi degli identificatori di licenza`_.
+
+   - Exception-Text:
+
+     Tutto il testo che compare dopo questa etichetta viene trattato
+     come se fosse parte del testo originale della licenza.
+
+   Esempi::
+
+      SPDX-Exception-Identifier: Linux-syscall-note
+      SPDX-URL: https://spdx.org/licenses/Linux-syscall-note.html
+      SPDX-Licenses: GPL-2.0, GPL-2.0+, GPL-1.0+, LGPL-2.0, LGPL-2.0+, LGPL-2.1, LGPL-2.1+
+      Usage-Guidance:
+        This exception is used together with one of the above SPDX-Licenses
+	to mark user-space API (uapi) header files so they can be included
+	into non GPL compliant user-space application code.
+        To use this exception add it with the keyword WITH to one of the
+	identifiers in the SPDX-Licenses tag:
+	  SPDX-License-Identifier: <SPDX-License> WITH Linux-syscall-note
+      Exception-Text:
+        Full exception text
+
+   ::
+
+      SPDX-Exception-Identifier: GCC-exception-2.0
+      SPDX-URL: https://spdx.org/licenses/GCC-exception-2.0.html
+      SPDX-Licenses: GPL-2.0, GPL-2.0+
+      Usage-Guidance:
+        The "GCC Runtime Library exception 2.0" is used together with one
+	of the above SPDX-Licenses for code imported from the GCC runtime
+	library.
+        To use this exception add it with the keyword WITH to one of the
+	identifiers in the SPDX-Licenses tag:
+	  SPDX-License-Identifier: <SPDX-License> WITH GCC-exception-2.0
+      Exception-Text:
+        Full exception text
+
+Per ogni identificatore di licenza SPDX e per le eccezioni dev'esserci un file
+nella sotto-cartella LICENSES.  Questo è necessario per permettere agli
+strumenti di effettuare verifiche (come checkpatch.pl), per avere le licenze
+disponibili per la lettura e per estrarre i diritti dai sorgenti, così come
+raccomandato da diverse organizzazioni FOSS, per esempio l'`iniziativa FSFE
+REUSE <https://reuse.software/>`_.
+
+_`MODULE_LICENSE`
+-----------------
+
+   I moduli del kernel necessitano di un'etichetta MODULE_LICENSE(). Questa
+   etichetta non sostituisce le informazioni sulla licenza del codice sorgente
+   (SPDX-License-Identifier) né fornisce informazioni che esprimono o
+   determinano l'esatta licenza sotto la quale viene rilasciato.
+
+   Il solo scopo di questa etichetta è quello di fornire sufficienti
+   informazioni al caricatore di moduli del kernel, o agli strumenti in spazio
+   utente, per capire se il modulo è libero o proprietario.
+
+   Le stringe di licenza valide per MODULE_LICENSE() sono:
+
+    ============================= =============================================
+    "GPL"			  Il modulo è licenziato con la GPL versione 2.
+				  Questo non fa distinzione fra GPL'2.0-only o
+				  GPL-2.0-or-later. L'esatta licenza può essere
+				  determinata solo leggendo i corrispondenti
+				  file sorgenti.
+
+    "GPL v2"			  Stesso significato di "GPL". Esiste per
+				  motivi storici.
+
+    "GPL and additional rights"   Questa è una variante che esiste per motivi
+				  storici che indica che i sorgenti di un
+				  modulo sono rilasciati sotto una variante
+				  della licenza GPL v2 e quella MIT. Per favore
+				  non utilizzatela per codice nuovo.
+
+    "Dual MIT/GPL"		  Questo è il modo corretto per esprimere il
+				  il fatto che il modulo è rilasciato con
+				  doppia licenza a scelta fra: una variante
+				  della GPL v2 o la licenza MIT.
+
+    "Dual BSD/GPL"		  Questo modulo è rilasciato con doppia licenza
+				  a scelta fra: una variante della GPL v2 o la
+				  licenza BSD. La variante esatta della licenza
+				  BSD può essere determinata solo attraverso i
+				  corrispondenti file sorgenti.
+
+    "Dual MPL/GPL"		  Questo modulo è rilasciato con doppia licenza
+				  a scelta fra: una variante della GPL v2 o la
+				  Mozilla Public License (MPL). La variante
+				  esatta della licenza MPL può essere
+				  determinata solo attraverso i corrispondenti
+				  file sorgenti.
+
+    "Proprietary"		  Questo modulo è rilasciato con licenza
+				  proprietaria. Questa stringa è solo per i
+				  moduli proprietari di terze parti e non può
+				  essere usata per quelli che risiedono nei
+				  sorgenti del kernel. I moduli etichettati in
+				  questo modo stanno contaminando il kernel e
+				  gli viene assegnato un flag 'P'; quando
+				  vengono caricati, il caricatore di moduli del
+				  kernel si rifiuterà di collegare questi
+				  moduli ai simboli che sono stati esportati
+				  con EXPORT_SYMBOL_GPL().

+=========================================
+La guida a PGP per manutentori del kernel
+=========================================
+
+:Author: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
+
+Questo documento è destinato agli sviluppatori del kernel Linux, in particolar
+modo ai manutentori. Contiene degli approfondimenti riguardo informazioni che
+sono state affrontate in maniera più generale nella sezione
+"`Protecting Code Integrity`_" pubblicata dalla Linux Foundation.
+Per approfondire alcuni argomenti trattati in questo documento è consigliato
+leggere il documento sopraindicato
+
+.. _`Protecting Code Integrity`: https://github.com/lfit/itpol/blob/master/protecting-code-integrity.md
+
+Il ruolo di PGP nello sviluppo del kernel Linux
+===============================================
+
+PGP aiuta ad assicurare l'integrità del codice prodotto dalla comunità
+di sviluppo del kernel e, in secondo luogo, stabilisce canali di comunicazione
+affidabili tra sviluppatori attraverso lo scambio di email firmate con PGP.
+
+Il codice sorgente del kernel Linux è disponibile principalmente in due
+formati:
+
+- repositori distribuiti di sorgenti (git)
+- rilasci periodici di istantanee (archivi tar)
+
+Sia i repositori git che gli archivi tar portano le firme PGP degli
+sviluppatori che hanno creato i rilasci ufficiali del kernel. Queste firme
+offrono una garanzia crittografica che le versioni scaricabili rese disponibili
+via kernel.org, o altri portali, siano identiche a quelle che gli sviluppatori
+hanno sul loro posto di lavoro. A tal scopo:
+
+- i repositori git forniscono firme PGP per ogni tag
+- gli archivi tar hanno firme separate per ogni archivio
+
+.. _it_devs_not_infra:
+
+Fidatevi degli sviluppatori e non dell'infrastruttura
+-----------------------------------------------------
+
+Fin dal 2011, quando i sistemi di kernel.org furono compromessi, il principio
+generale del progetto Kernel Archives è stato quello di assumere che qualsiasi
+parte dell'infrastruttura possa essere compromessa in ogni momento. Per questa
+ragione, gli amministratori hanno intrapreso deliberatemene dei passi per
+enfatizzare che la fiducia debba risiedere sempre negli sviluppatori e mai nel
+codice che gestisce l'infrastruttura, indipendentemente da quali che siano le
+pratiche di sicurezza messe in atto.
+
+Il principio sopra indicato è la ragione per la quale è necessaria questa
+guida. Vogliamo essere sicuri che il riporre la fiducia negli sviluppatori
+non sia fatto semplicemente per incolpare qualcun'altro per future falle di
+sicurezza. L'obiettivo è quello di fornire una serie di linee guida che gli
+sviluppatori possano seguire per creare un ambiente di lavoro sicuro e
+salvaguardare le chiavi PGP usate nello stabilire l'integrità del kernel Linux
+stesso.

+
+Strumenti PGP
+=============
+
+Usare GnuPG v2
+--------------
+
+La vostra distribuzione potrebbe avere già installato GnuPG, dovete solo
+verificare che stia utilizzando la versione 2.x e non la serie 1.4 --
+molte distribuzioni forniscono entrambe, di base il comando ''gpg''
+invoca GnuPG v.1. Per controllate usate::
+
+    $ gpg --version | head -n1
+
+Se visualizzate ``gpg (GnuPG) 1.4.x``, allora state usando GnuPG v.1.
+Provate il comando ``gpg2`` (se non lo avete, potreste aver bisogno
+di installare il pacchetto gnupg2)::
+
+    $ gpg2 --version | head -n1
+
+Se visualizzate  ``gpg (GnuPG) 2.x.x``, allora siete pronti a partire.
+Questa guida assume che abbiate la versione 2.2.(o successiva) di GnuPG.
+Se state usando la versione 2.0, alcuni dei comandi indicati qui non
+funzioneranno, in questo caso considerate un aggiornamento all'ultima versione,
+la 2.2. Versioni di gnupg-2.1.11 e successive dovrebbero essere compatibili
+per gli obiettivi di questa guida.
+
+Se avete entrambi i comandi: ``gpg`` e ``gpg2``, assicuratevi di utilizzare
+sempre la versione V2, e non quella vecchia. Per evitare errori potreste creare
+un alias::
+
+    $ alias gpg=gpg2
+
+Potete mettere questa opzione nel vostro  ``.bashrc`` in modo da essere sicuri.
+
+Configurare le opzioni di gpg-agent
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+L'agente GnuPG è uno strumento di aiuto che partirà automaticamente ogni volta
+che userete il comando ``gpg`` e funzionerà in background con l'obiettivo di
+individuare la passphrase. Ci sono due opzioni che dovreste conoscere
+per personalizzare la scadenza della passphrase nella cache:
+
+- ``default-cache-ttl`` (secondi): Se usate ancora la stessa chiave prima
+  che il time-to-live termini, il conto alla rovescia si resetterà per un
+  altro periodo. Di base è di 600 (10 minuti).
+
+- ``max-cache-ttl`` (secondi): indipendentemente da quanto sia recente l'ultimo
+  uso della chiave da quando avete inserito la passphrase, se il massimo
+  time-to-live è scaduto, dovrete reinserire nuovamente la passphrase.
+  Di base è di 30 minuti.
+
+Se ritenete entrambe questi valori di base troppo corti (o troppo lunghi),
+potete creare il vostro file ``~/.gnupg/gpg-agent.conf`` ed impostare i vostri
+valori::
+
+    # set to 30 minutes for regular ttl, and 2 hours for max ttl
+    default-cache-ttl 1800
+    max-cache-ttl 7200
+
+.. note::
+
+    Non è più necessario far partire l'agente gpg manualmente all'inizio della
+    vostra sessione. Dovreste controllare i file rc per rimuovere tutto ciò che
+    riguarda vecchie le versioni di GnuPG, poiché potrebbero non svolgere più
+    bene il loro compito.
+
+Impostare un *refresh* con cronjob
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Potreste aver bisogno di rinfrescare regolarmente il vostro portachiavi in
+modo aggiornare le chiavi pubbliche di altre persone, lavoro che è svolto
+al meglio con un cronjob giornaliero::
+
+    @daily /usr/bin/gpg2 --refresh >/dev/null 2>&1
+
+Controllate il percorso assoluto del vostro comando ``gpg`` o ``gpg2`` e usate
+il comando ``gpg2`` se per voi ``gpg`` corrisponde alla versione GnuPG v.1.

+
+Proteggere la vostra chiave PGP primaria
 ========================================
-Guida a PGP per i manutentori del kernel
-========================================
+
+Questa guida parte dal presupposto che abbiate già una chiave PGP che usate
+per lo sviluppo del kernel Linux. Se non ne avete ancora una, date uno sguardo
+al documento "`Protecting Code Integrity`_" che abbiamo menzionato prima.
+
+Dovreste inoltre creare una nuova chiave se quella attuale è inferiore a 2048
+bit (RSA).
+
+Chiave principale o sottochiavi
+-------------------------------
+
+Le sottochiavi sono chiavi PGP totalmente indipendenti, e sono collegate alla
+chiave principale attraverso firme certificate. È quindi importante
+comprendere i seguenti punti:
+
+1. Non ci sono differenze tecniche tra la chiave principale e la sottochiave.
+2. In fesa di creazione, assegniamo limitazioni funzionali ad ogni chiave
+   assegnando capacità specifiche.
+3. Una chiave PGP può avere 4 capacità:
+
+   - **[S]** può essere usata per firmare
+   - **[E]** può essere usata per criptare
+   - **[A]** può essere usata per autenticare
+   - **[C]** può essere usata per certificare altre chiavi
+
+4. Una singola chiave può avere più capacità
+5. Una sottochiave è completamente indipendente dalla chiave principale.
+   Un messaggio criptato con la sottochiave non può essere decrittato con
+   quella principale. Se perdete la vostra sottochiave privata, non può
+   essere rigenerata in nessun modo da quella principale.
+
+La chiave con capacità **[C]** (certify) è identificata come la chiave
+principale perché è l'unica che può essere usata per indicare la relazione
+con altre chiavi. Solo la chiave **[C]** può essere usata per:
+
+- Aggiungere o revocare altre chiavi (sottochiavi) che hanno capacità S/E/A
+- Aggiungere, modificare o eliminare le identità (unids) associate alla chiave
+- Aggiungere o modificare la data di termine di sé stessa o di ogni sottochiave
+- Firmare le chiavi di altre persone a scopo di creare una rete di fiducia
+
+Di base, alla creazione di nuove chiavi, GnuPG genera quanto segue:
+
+- Una chiave madre che porta sia la capacità di certificazione che quella
+  di firma (**[SC]**)
+- Una sottochiave separata con capacità di criptaggio (**[E]**)
+
+Se avete usato i parametri di base per generare la vostra chiave, quello
+sarà il risultato. Potete verificarlo utilizzando ``gpg --list-secret-keys``,
+per esempio::
+
+    sec   rsa2048 2018-01-23 [SC] [expires: 2020-01-23]
+          000000000000000000000000AAAABBBBCCCCDDDD
+    uid           [ultimate] Alice Dev <adev@kernel.org>
+    ssb   rsa2048 2018-01-23 [E] [expires: 2020-01-23]
+
+Qualsiasi chiave che abbia la capacità **[C]** è la vostra chiave madre,
+indipendentemente da quali altre capacità potreste averle assegnato.
+
+La lunga riga sotto la voce ``sec`` è la vostra impronta digitale --
+negli esempi che seguono, quando vedere ``[fpr]`` ci si riferisce a questa
+stringa di 40 caratteri.
+
+Assicuratevi che la vostra passphrase sia forte
+-----------------------------------------------
+
+GnuPG utilizza le passphrases per criptare la vostra chiave privata prima
+di salvarla sul disco. In questo modo, anche se il contenuto della vostra
+cartella ``.gnupg`` venisse letto o trafugato nella sia interezza, gli
+attaccanti non potrebbero comunque utilizzare le vostre chiavi private senza
+aver prima ottenuto la passphrase per decriptarle.
+
+È assolutamente essenziale che le vostre chiavi private siano protette da
+una passphrase forte. Per impostarla o cambiarla, usate::
+
+    $ gpg --change-passphrase [fpr]
+
+Create una sottochiave di firma separata
+----------------------------------------
+
+Il nostro obiettivo è di proteggere la chiave primaria spostandola su un
+dispositivo sconnesso dalla rete, dunque se avete solo una chiave combinata
+**[SC]** allora dovreste creare una sottochiave di firma separata::
+
+    $ gpg --quick-add-key [fpr] ed25519 sign
+
+Ricordate di informare il keyserver del vostro cambiamento, cosicché altri
+possano ricevere la vostra nuova sottochiave::
+
+    $ gpg --send-key [fpr]
+
+.. note:: Supporto ECC in GnuPG
+    GnuPG 2.1 e successivi supportano pienamente *Elliptic Curve Cryptography*,
+    con la possibilità di combinare sottochiavi ECC con le tradizionali chiavi
+    primarie RSA. Il principale vantaggio della crittografia ECC è che è molto
+    più veloce da calcolare e crea firme più piccole se confrontate byte per
+    byte con le chiavi RSA a più di 2048 bit. A meno che non pensiate di
+    utilizzare un dispositivo smartcard che non supporta le operazioni ECC, vi
+    raccomandiamo ti creare sottochiavi di firma ECC per il vostro lavoro col
+    kernel.
+
+    Se per qualche ragione preferite rimanere con sottochiavi RSA, nel comando
+    precedente, sostituite "ed25519" con "rsa2048".
+
+Copia di riserva della chiave primaria per gestire il recupero da disastro
+--------------------------------------------------------------------------
+
+Maggiori sono le firme di altri sviluppatori che vengono applicate alla vostra,
+maggiori saranno i motivi per avere una copia di riserva che non sia digitale,
+al fine di effettuare un recupero da disastro.
+
+Il modo migliore per creare una copia fisica della vostra chiave privata è
+l'uso del programma ``paperkey``. Consultate ``man paperkey`` per maggiori
+dettagli sul formato dell'output ed i suoi punti di forza rispetto ad altre
+soluzioni. Paperkey dovrebbe essere già pacchettizzato per la maggior parte
+delle distribuzioni.
+
+Eseguite il seguente comando per creare una copia fisica di riserva della
+vostra chiave privata::
+
+    $ gpg --export-secret-key [fpr] | paperkey -o /tmp/key-backup.txt
+
+Stampate il file (o fate un pipe direttamente verso lpr), poi prendete
+una penna e scrivete la passphare sul margine del foglio.  **Questo è
+caldamente consigliato** perché la copia cartacea è comunque criptata con
+la passphrase, e se mai doveste cambiarla non vi ricorderete qual'era al
+momento della creazione di quella copia -- *garantito*.
+
+Mettete la copia cartacea e la passphrase scritta a mano in una busta e
+mettetela in un posto sicuro e ben protetto, preferibilmente fuori casa,
+magari in una cassetta di sicurezza in banca.
+
+.. note::
+
+    Probabilmente la vostra stampante non è più quello stupido dispositivo
+    connesso alla porta parallela, ma dato che il suo output è comunque
+    criptato con la passphrase, eseguire la stampa in un sistema "cloud"
+    moderno dovrebbe essere comunque relativamente sicuro. Un'opzione potrebbe
+    essere quella di cambiare la passphrase della vostra chiave primaria
+    subito dopo aver finito con paperkey.
+
+Copia di riserva di tutta la cartella GnuPG
+-------------------------------------------
 
 .. warning::
 
-    TODO ancora da tradurre
+    **!!!Non saltate questo passo!!!**
+
+Quando avete bisogno di recuperare le vostre chiavi PGP è importante avere
+una copia di riserva pronta all'uso. Questo sta su un diverso piano di
+prontezza rispetto al recupero da disastro che abbiamo risolto con
+``paperkey``. Vi affiderete a queste copie esterne quando dovreste usare la
+vostra chiave Certify -- ovvero quando fate modifiche alle vostre chiavi o
+firmate le chiavi di altre persone ad una conferenza o ad un gruppo d'incontro.
+
+Incominciate con una piccola chiavetta di memoria USB (preferibilmente due)
+che userete per le copie di riserva. Dovrete criptarle usando LUKS -- fate
+riferimento alla documentazione della vostra distribuzione per capire come
+fare.
+
+Per la passphrase di criptazione, potete usare la stessa della vostra chiave
+primaria.
+
+Una volta che il processo di criptazione è finito, reinserite il disco USB ed
+assicurativi che venga montato correttamente. Copiate interamente la cartella
+``.gnugp`` nel disco criptato::
+
+    $ cp -a ~/.gnupg /media/disk/foo/gnupg-backup
+
+Ora dovreste verificare che tutto continui a funzionare::
+
+    $ gpg --homedir=/media/disk/foo/gnupg-backup --list-key [fpr]
+
+Se non vedete errori, allora dovreste avere fatto tutto con successo.
+Smontate il disco USB, etichettatelo per bene di modo da evitare di
+distruggerne il contenuto non appena vi serve una chiavetta USB a caso, ed
+infine mettetelo in un posto sicuro -- ma non troppo lontano, perché vi servirà
+di tanto in tanto per modificare le identità, aggiungere o revocare
+sottochiavi, o firmare le chiavi di altre persone.
+
+Togliete la chiave primaria dalla vostra home
+---------------------------------------------
+
+I file che si trovano nella vostra cartella home non sono poi così ben protetti
+come potreste pensare. Potrebbero essere letti o trafugati in diversi modi:
+
+- accidentalmente quando fate una rapida copia della cartella home per
+  configurare una nuova postazione
+- da un amministratore di sistema negligente o malintenzionato
+- attraverso copie di riserva insicure
+- attraverso malware installato in alcune applicazioni (browser, lettori PDF,
+  eccetera)
+- attraverso coercizione quando attraversate confini internazionali
+
+Proteggere la vostra chiave con una buona passphare aiuta notevolmente a
+ridurre i rischi elencati qui sopra, ma le passphrase possono essere scoperte
+attraverso i keylogger, il shoulder-surfing, o altri modi. Per questi motivi,
+nella configurazione si raccomanda di rimuove la chiave primaria dalla vostra
+cartella home e la si archivia su un dispositivo disconnesso.
+
+.. warning::
+
+    Per favore, fate riferimento alla sezione precedente e assicuratevi
+    di aver fatto una copia di riserva totale della cartella GnuPG. Quello
+    che stiamo per fare renderà la vostra chiave inutile se non avete delle
+    copie di riserva utilizzabili!
+
+Per prima cosa, identificate il keygrip della vostra chiave primaria::
+
+    $ gpg --with-keygrip --list-key [fpr]
+
+L'output assomiglierà a questo::
+
+    pub   rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+          000000000000000000000000AAAABBBBCCCCDDDD
+          Keygrip = 1111000000000000000000000000000000000000
+    uid           [ultimate] Alice Dev <adev@kernel.org>
+    sub   rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+          Keygrip = 2222000000000000000000000000000000000000
+    sub   ed25519 2018-01-24 [S]
+          Keygrip = 3333000000000000000000000000000000000000
+
+Trovate la voce keygrid che si trova sotto alla riga ``pub`` (appena sotto
+all'impronta digitale della chiave primaria). Questo corrisponderà direttamente
+ad un file nella cartella ``~/.gnupg``::
+
+    $ cd ~/.gnupg/private-keys-v1.d
+    $ ls
+    1111000000000000000000000000000000000000.key
+    2222000000000000000000000000000000000000.key
+    3333000000000000000000000000000000000000.key
+
+Quello che dovrete fare è rimuovere il file .key che corrisponde al keygrip
+della chiave primaria::
+
+    $ cd ~/.gnupg/private-keys-v1.d
+    $ rm 1111000000000000000000000000000000000000.key
+
+Ora, se eseguite il comando ``--list-secret-keys``, vedrete che la chiave
+primaria non compare più (il simbolo ``#`` indica che non è disponibile)::
+
+    $ gpg --list-secret-keys
+    sec#  rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+          000000000000000000000000AAAABBBBCCCCDDDD
+    uid           [ultimate] Alice Dev <adev@kernel.org>
+    ssb   rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+    ssb   ed25519 2018-01-24 [S]
+
+Dovreste rimuovere anche i file ``secring.gpg`` che si trovano nella cartella
+``~/.gnupg``, in quanto rimasugli delle versioni precedenti di GnuPG.
+
+Se non avete la cartella "private-keys-v1.d"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Se non avete la cartella ``~/.gnupg/private-keys-v1.d``, allora le vostre
+chiavi segrete sono ancora salvate nel vecchio file ``secring.gpg`` usato
+da GnuPG v1. Effettuare una qualsiasi modifica alla vostra chiave, come
+cambiare la passphare o aggiungere una sottochiave, dovrebbe convertire
+automaticamente il vecchio formato ``secring.gpg``nel nuovo
+``private-keys-v1.d``.
+
+Una volta che l'avete fatto, assicuratevi di rimuovere il file ``secring.gpg``,
+che continua a contenere la vostra chiave privata.
+
+.. _it_smartcards:
+
+Spostare le sottochiavi in un apposito dispositivo criptato
+===========================================================
+
+Nonostante la chiave primaria sia ora al riparo da occhi e mani indiscrete,
+le sottochiavi si trovano ancora nella vostra cartella home. Chiunque riesca
+a mettere le sue mani su quelle chiavi riuscirà a decriptare le vostre
+comunicazioni o a falsificare le vostre firme (se conoscono la passphrase).
+Inoltre, ogni volta che viene fatta un'operazione con GnuPG, le chiavi vengono
+caricate nella memoria di sistema e potrebbero essere rubate con l'uso di
+malware sofisticati (pensate a Meltdown e a Spectre).
+
+Il miglior modo per proteggere le proprie chiave è di spostarle su un
+dispositivo specializzato in grado di effettuare operazioni smartcard.
+
+I benefici di una smartcard
+---------------------------
+
+Una smartcard contiene un chip crittografico che è capace di immagazzinare
+le chiavi private ed effettuare operazioni crittografiche direttamente sulla
+carta stessa. Dato che la chiave non lascia mai la smartcard, il sistema
+operativo usato sul computer non sarà in grado di accedere alle chiavi.
+Questo è molto diverso dai dischi USB criptati che abbiamo usato allo scopo di
+avere una copia di riserva sicura -- quando il dispositivo USB è connesso e
+montato, il sistema operativo potrà accedere al contenuto delle chiavi private.
+
+L'uso di un disco USB criptato non può sostituire le funzioni di un dispositivo
+capace di operazioni di tipo smartcard.
+
+Dispositivi smartcard disponibili
+---------------------------------
+
+A meno che tutti i vostri computer dispongano di lettori smartcard, il modo
+più semplice è equipaggiarsi di un dispositivo USB specializzato che
+implementi le funzionalità delle smartcard.  Sul mercato ci sono diverse
+soluzioni disponibili:
+
+- `Nitrokey Start`_: è Open hardware e Free Software, è basata sul progetto
+  `GnuK`_ della FSIJ. Ha il supporto per chiavi ECC, ma meno funzionalità di
+  sicurezza (come la resistenza alla manomissione o alcuni attacchi ad un
+  canale laterale).
+- `Nitrokey Pro`_: è simile alla Nitrokey Start, ma è più resistente alla
+  manomissione e offre più funzionalità di sicurezza, ma l'ECC.
+- `Yubikey 4`_: l'hardware e il software sono proprietari, ma è più economica
+  della  Nitrokey Pro ed è venduta anche con porta USB-C il che è utile con i
+  computer portatili più recenti. In aggiunta, offre altre funzionalità di
+  sicurezza come FIDO, U2F, ma non l'ECC
+
+`Su LWN c'è una buona recensione`_ dei modelli elencati qui sopra e altri.
+Se volete usare chiavi ECC, la vostra migliore scelta sul mercato è la
+Nitrokey Start.

+
+Configurare il vostro dispositivo smartcard
+-------------------------------------------
+
+Il vostro dispositivo smartcard dovrebbe iniziare a funzionare non appena
+lo collegate ad un qualsiasi computer Linux moderno. Potete verificarlo
+eseguendo::
+
+    $ gpg --card-status
+
+Se vedete tutti i dettagli della smartcard, allora ci siamo. Sfortunatamente,
+affrontare tutti i possibili motivi per cui le cose potrebbero non funzionare
+non è lo scopo di questa guida. Se avete problemi nel far funzionare la carta
+con GnuPG, cercate aiuto attraverso i soliti canali di supporto.
+
+Per configurare la vostra smartcard, dato che non c'è una via facile dalla
+riga di comando, dovrete usate il menu di GnuPG::
+
+    $ gpg --card-edit
+    [...omitted...]
+    gpg/card> admin
+    Admin commands are allowed
+    gpg/card> passwd
+
+Dovreste impostare il PIN dell'utente (1), quello dell'amministratore (3) e il
+codice di reset (4). Assicuratevi di annotare e salvare questi codici in un
+posto sicuro -- specialmente il PIN dell'amministratore e il codice di reset
+(che vi permetterà di azzerare completamente la smartcard).  Il PIN
+dell'amministratore viene usato così raramente che è inevitabile dimenticarselo
+se non lo si annota.
+
+Tornando al nostro menu, potete impostare anche altri valori (come il nome,
+il sesso, informazioni d'accesso, eccetera), ma non sono necessari e aggiunge
+altre informazioni sulla carta che potrebbero trapelare in caso di smarrimento.
+
+.. note::
+
+    A dispetto del nome "PIN", né il PIN utente né quello dell'amministratore
+    devono essere esclusivamente numerici.
+
+Spostare le sottochiavi sulla smartcard
+---------------------------------------
+
+Uscite dal menu (usando "q") e salverete tutte le modifiche. Poi, spostiamo
+tutte le sottochiavi sulla smartcard. Per la maggior parte delle operazioni
+vi serviranno sia la passphrase della chiave PGP che il PIN
+dell'amministratore::
+
+    $ gpg --edit-key [fpr]
+
+    Secret subkeys are available.
+
+    pub  rsa2048/AAAABBBBCCCCDDDD
+         created: 2018-01-23  expires: 2020-01-23  usage: SC
+         trust: ultimate      validity: ultimate
+    ssb  rsa2048/1111222233334444
+         created: 2018-01-23  expires: never       usage: E
+    ssb  ed25519/5555666677778888
+         created: 2017-12-07  expires: never       usage: S
+    [ultimate] (1). Alice Dev <adev@kernel.org>
+
+    gpg>
+
+Usando ``--edit-key`` si tornerà alla modalità menu e noterete che
+la lista delle chiavi è leggermente diversa. Da questo momento in poi,
+tutti i comandi saranno eseguiti nella modalità menu, come indicato
+da ``gpg>``.
+
+Per prima cosa, selezioniamo la chiave che verrà messa sulla carta --
+potete farlo digitando ``key 1`` (è la prima della lista, la sottochiave
+**[E]**)::
+
+    gpg> key 1
+
+Nel'output dovreste vedere ``ssb*`` associato alla chiave **[E]**. Il simbolo
+``*`` indica che la chiave è stata "selezionata". Funziona come un
+interruttore, ovvero se scrivete nuovamente ``key 1``, il simbolo ``*`` sparirà
+e la chiave non sarà più selezionata.
+
+Ora, spostiamo la chiave sulla smartcard::
+
+    gpg> keytocard
+    Please select where to store the key:
+       (2) Encryption key
+    Your selection? 2
+
+Dato che è la nostra chiave  **[E]**, ha senso metterla nella sezione criptata.
+Quando confermerete la selezione, vi verrà chiesta la passphrase della vostra
+chiave PGP, e poi il PIN dell'amministratore. Se il comando ritorna senza
+errori, allora la vostra chiave è stata spostata con successo.
+
+**Importante**: digitate nuovamente ``key 1`` per deselezionare la prima chiave
+e selezionate la seconda chiave **[S]** con ``key 2``::
+
+    gpg> key 1
+    gpg> key 2
+    gpg> keytocard
+    Please select where to store the key:
+       (1) Signature key
+       (3) Authentication key
+    Your selection? 1
+
+Potete usare la chiave **[S]** sia per firmare che per autenticare, ma vogliamo
+che sia nella sezione di firma, quindi scegliete (1). Ancora una volta, se il
+comando ritorna senza errori, allora l'operazione è avvenuta con successo::
+
+    gpg> q
+    Save changes? (y/N) y
+
+Salvando le modifiche cancellerete dalla vostra cartella home tutte le chiavi
+che avete spostato sulla carta (ma questo non è un problema, perché abbiamo
+fatto delle copie di sicurezza nel caso in cui dovessimo configurare una
+nuova smartcard).
+
+Verificare che le chiavi siano state spostate
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Ora, se doveste usare l'opzione ``--list-secret-keys``, vedrete una
+sottile differenza nell'output::
+
+    $ gpg --list-secret-keys
+    sec#  rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+          000000000000000000000000AAAABBBBCCCCDDDD
+    uid           [ultimate] Alice Dev <adev@kernel.org>
+    ssb>  rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+    ssb>  ed25519 2018-01-24 [S]
+
+Il simbolo ``>`` in ``ssb>`` indica che la sottochiave è disponibile solo
+nella smartcard. Se tornate nella vostra cartella delle chiavi segrete e
+guardate al suo contenuto, noterete che i file ``.key`` sono stati sostituiti
+con degli stub::
+
+    $ cd ~/.gnupg/private-keys-v1.d
+    $ strings *.key | grep 'private-key'
+
+Per indicare che i file sono solo degli stub e che in realtà il contenuto è
+sulla smartcard, l'output dovrebbe mostrarvi ``shadowed-private-key``.
+
+Verificare che la smartcard funzioni
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Per verificare che la smartcard funzioni come dovuto, potete creare
+una firma::
+
+    $ echo "Hello world" | gpg --clearsign > /tmp/test.asc
+    $ gpg --verify /tmp/test.asc
+
+Col primo comando dovrebbe chiedervi il PIN della smartcard, e poi dovrebbe
+mostrare "Good signature" dopo l'esecuzione di ``gpg --verify``.
+
+Complimenti, siete riusciti a rendere estremamente difficile il furto della
+vostra identità digitale di sviluppatore.
+
+Altre operazioni possibili con GnuPG
+------------------------------------
+
+Segue un breve accenno ad alcune delle operazioni più comuni che dovrete
+fare con le vostre chiavi PGP.
+
+Montare il disco con la chiave primaria
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Vi servirà la vostra chiave principale per tutte le operazioni che seguiranno,
+per cui per prima cosa dovrete accedere ai vostri backup e dire a GnuPG di
+usarli::
+
+    $ export GNUPGHOME=/media/disk/foo/gnupg-backup
+    $ gpg --list-secret-keys
+
+Dovete assicurarvi di vedere ``sec`` e non ``sec#`` nell'output del programma
+(il simbolo ``#`` significa che la chiave non è disponibile e che state ancora
+utilizzando la vostra solita cartella di lavoro).
+
+Estendere la data di scadenza di una chiave
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+La chiave principale ha una data di scadenza di 2 anni dal momento della sua
+creazione. Questo per motivi di sicurezza e per rendere obsolete le chiavi
+che, eventualmente, dovessero sparire dai keyserver.
+
+Per estendere di un anno, dalla data odierna, la scadenza di una vostra chiave,
+eseguite::
+
+    $ gpg --quick-set-expire [fpr] 1y
+
+Se per voi è più facile da memorizzare, potete anche utilizzare una data
+specifica (per esempio, il vostro compleanno o capodanno)::
+
+    $ gpg --quick-set-expire [fpr] 2020-07-01
+
+Ricordatevi di inviare l'aggiornamento ai keyserver::
+
+    $ gpg --send-key [fpr]
+
+Aggiornare la vostra cartella di lavoro dopo ogni modifica
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Dopo aver fatto delle modifiche alle vostre chiavi usando uno spazio a parte,
+dovreste importarle nella vostra cartella di lavoro abituale::
+
+    $ gpg --export | gpg --homedir ~/.gnupg --import
+    $ unset GNUPGHOME
+
+
+Usare PGP con Git
+=================
+
+Una delle caratteristiche fondanti di Git è la sua natura decentralizzata --
+una volta che il repositorio è stato clonato sul vostro sistema, avete la
+storia completa del progetto, inclusi i suoi tag, i commit ed i rami. Tuttavia,
+con i centinaia di repositori clonati che ci sono in giro, come si fa a
+verificare che la loro copia di linux.git non è stata manomessa da qualcuno?
+
+Oppure, cosa succede se viene scoperta una backdoor nel codice e la riga
+"Autore" dice che sei stato tu, mentre tu sei abbastanza sicuro di
+`non averci niente a che fare`_?
+
+Per risolvere entrambi i problemi, Git ha introdotto l'integrazione con PGP.
+I tag firmati dimostrano che il repositorio è integro assicurando che il suo
+contenuto è lo stesso che si trova sulle macchine degli sviluppatori che hanno
+creato il tag; mentre i commit firmati rendono praticamente impossibile
+ad un malintenzionato di impersonarvi senza avere accesso alle vostre chiavi
+PGP.
+
+.. _`non averci niente a che fare`: https://github.com/jayphelps/git-blame-someone-else
+
+Configurare git per usare la vostra chiave PGP
+----------------------------------------------
+
+Se avete solo una chiave segreta nel vostro portachiavi, allora non avete nulla
+da fare in più dato che sarà la vostra chiave di base. Tuttavia, se doveste
+avere più chiavi segrete, potete dire a git quale dovrebbe usare (``[fpg]``
+è la vostra impronta digitale)::
+
+    $ git config --global user.signingKey [fpr]
+
+**IMPORTANTE**: se avete una comando dedicato per ``gpg2``, allora dovreste
+dire a git di usare sempre quello piuttosto che il vecchio comando ``gpg``::
+
+    $ git config --global gpg.program gpg2
+
+Come firmare i tag
+------------------
+
+Per creare un tag firmato, passate l'opzione ``-s`` al comando tag::
+
+    $ git tag -s [tagname]
+
+La nostra raccomandazione è quella di firmare sempre i tag git, perché
+questo permette agli altri sviluppatori di verificare che il repositorio
+git dal quale stanno prendendo il codice non è stato alterato intenzionalmente.
+
+Come verificare i tag firmati
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Per verificare un tag firmato, potete usare il comando ``verify-tag``::
+
+    $ git verify-tag [tagname]
+
+Se state prendendo un tag da un fork del repositorio del progetto, git
+dovrebbe verificare automaticamente la firma di quello che state prendendo
+e vi mostrerà il risultato durante l'operazione di merge::
+
+    $ git pull [url] tags/sometag
+
+Il merge conterrà qualcosa di simile::
+
+    Merge tag 'sometag' of [url]
+
+    [Tag message]
+
+    # gpg: Signature made [...]
+    # gpg: Good signature from [...]
+
+Se state verificando il tag di qualcun altro, allora dovrete importare
+la loro chiave PGP. Fate riferimento alla sezione ":ref:`it_verify_identities`"
+che troverete più avanti.
+
+Configurare git per firmare sempre i tag con annotazione
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Se state creando un tag con annotazione è molto probabile che vogliate
+firmarlo. Per imporre a git di firmare sempre un tag con annotazione,
+dovete impostare la seguente opzione globale::
+
+    $ git config --global tag.forceSignAnnotated true
+
+Come usare commit firmati
+-------------------------
+
+Creare dei commit firmati è facile, ma è molto più difficile utilizzarli
+nello sviluppo del kernel linux per via del fatto che ci si affida alle
+liste di discussione e questo modo di procedere non mantiene le firme PGP
+nei commit. In aggiunta, quando si usa *rebase* nel proprio repositorio
+locale per allinearsi al kernel anche le proprie firme PGP verranno scartate.
+Per questo motivo, la maggior parte degli sviluppatori del kernel non si
+preoccupano troppo di firmare i propri commit ed ignoreranno quelli firmati
+che si trovano in altri repositori usati per il proprio lavoro.
+
+Tuttavia, se avete il vostro repositorio di lavoro disponibile al pubblico
+su un qualche servizio di hosting git (kernel.org, infradead.org, ozlabs.org,
+o altri), allora la raccomandazione è di firmare tutti i vostri commit
+anche se gli sviluppatori non ne beneficeranno direttamente.
+
+Vi raccomandiamo di farlo per i seguenti motivi:
+
+1. Se dovesse mai esserci la necessità di fare delle analisi forensi o
+   tracciare la provenienza di un codice, anche sorgenti mantenuti
+   esternamente che hanno firme PGP sui commit avranno un certo valore a
+   questo scopo.
+2. Se dovesse mai capitarvi di clonare il vostro repositorio locale (per
+   esempio dopo un danneggiamento del disco), la firma vi permetterà di
+   verificare l'integrità del repositorio prima di riprendere il lavoro.
+3. Se qualcuno volesse usare *cherry-pick* sui vostri commit, allora la firma
+   permetterà di verificare l'integrità dei commit prima di applicarli.
+
+Creare commit firmati
+~~~~~~~~~~~~~~~~~~~~~
+
+Per creare un commit firmato, dovete solamente aggiungere l'opzione ``-S``
+al comando ``git commit`` (si usa la lettera maiuscola per evitare
+conflitti con un'altra opzione)::
+
+    $ git commit -S
+
+Configurare git per firmare sempre i commit
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Potete dire a git di firmare sempre i commit::
+
+    git config --global commit.gpgSign true
+
+.. note::
+
+    Assicuratevi di aver configurato ``gpg-agent`` prima di abilitare
+    questa opzione.
+
+.. _it_verify_identities:
+
+Come verificare l'identità degli sviluppatori del kernel
+========================================================
+
+Firmare i tag e i commit è facile, ma come si fa a verificare che la chiave
+usata per firmare qualcosa appartenga davvero allo sviluppatore e non ad un
+impostore?
+
+Configurare l'auto-key-retrieval usando WKD e DANE
+--------------------------------------------------
+
+Se non siete ancora in possesso di una vasta collezione di chiavi pubbliche
+di altri sviluppatori, allora potreste iniziare il vostro portachiavi
+affidandovi ai servizi di auto-scoperta e auto-recupero. GnuPG può affidarsi
+ad altre tecnologie di delega della fiducia, come DNSSEC e TLS, per sostenervi
+nel caso in cui iniziare una propria rete di fiducia da zero sia troppo
+scoraggiante.
+
+Aggiungete il seguente testo al vostro file ``~/.gnupg/gpg.conf``::
+
+    auto-key-locate wkd,dane,local
+    auto-key-retrieve
+
+La *DNS-Based Authentication of Named Entities* ("DANE") è un metodo
+per la pubblicazione di chiavi pubbliche su DNS e per renderle sicure usando
+zone firmate con DNSSEC. Il *Web Key Directory* ("WKD") è un metodo
+alternativo che usa https a scopo di ricerca. Quando si usano DANE o WKD
+per la ricerca di chiavi pubbliche, GnuPG validerà i certificati DNSSEC o TLS
+prima di aggiungere al vostro portachiavi locale le eventuali chiavi trovate.
+
+Kernel.org pubblica la WKD per tutti gli sviluppatori che hanno un account
+kernel.org. Una volta che avete applicato le modifiche al file ``gpg.conf``,
+potrete auto-recuperare le chiavi di Linus Torvalds e Greg Kroah-Hartman
+(se non le avete già)::
+
+    $ gpg --locate-keys torvalds@kernel.org gregkh@kernel.org
+
+Se avete un account kernel.org, al fine di rendere più utile l'uso di WKD
+da parte di altri sviluppatori del kernel, dovreste `aggiungere alla vostra
+chiave lo UID di kernel.org`_.
+
+.. _`aggiungere alla vostra chiave lo UID di kernel.org`: https://korg.wiki.kernel.org/userdoc/mail#adding_a_kernelorg_uid_to_your_pgp_key
+
+Web of Trust (WOT) o Trust on First Use (TOFU)
+----------------------------------------------
+
+PGP incorpora un meccanismo di delega della fiducia conosciuto come
+"Web of Trust". Di base, questo è un tentativo di sostituire la necessità
+di un'autorità certificativa centralizzata tipica del mondo HTTPS/TLS.
+Invece di avere svariati produttori software che decidono chi dovrebbero
+essere le entità di certificazione di cui dovreste fidarvi, PGP lascia
+la responsabilità ad ogni singolo utente.
+
+Sfortunatamente, solo poche persone capiscono come funziona la rete di fiducia.
+Nonostante sia un importante aspetto della specifica OpenPGP, recentemente
+le versioni di GnuPG (2.2 e successive) hanno implementato un meccanisco
+alternativo chiamato "Trust on First Use" (TOFU). Potete pensare a TOFU come
+"ad un approccio all fidicia simile ad SSH". In SSH, la prima volta che vi
+connettete ad un sistema remoto, l'impronta digitale della chiave viene
+registrata e ricordata. Se la chiave dovesse cambiare in futuro, il programma
+SSH vi avviserà e si rifiuterà di connettersi, obbligandovi a prendere una
+decisione circa la fiducia che riponete nella nuova chiave. In modo simile,
+la prima volta che importate la chiave PGP di qualcuno, si assume sia valida.
+Se ad un certo punto GnuPG trova un'altra chiave con la stessa identità,
+entrambe, la vecchia e la nuova, verranno segnate come invalide e dovrete
+verificare manualmente quale tenere.
+
+Vi raccomandiamo di usare il meccanisco TOFU+PGP (che è la nuova configurazione
+di base di GnuPG v2). Per farlo, aggiungete (o modificate) l'impostazione
+``trust-model`` in ``~/.gnupg/gpg.conf``::
+
+    trust-model tofu+pgp
+
+Come usare i keyserver in sicurezza
+-----------------------------------
+Se ottenete l'errore "No public key" quando cercate di validate il tag di
+qualcuno, allora dovreste cercare quella chiave usando un keyserver. È
+importante tenere bene a mente che non c'è alcuna garanzia che la chiave
+che avete recuperato da un keyserver PGP appartenga davvero alla persona
+reale -- è progettato così. Dovreste usare il Web of Trust per assicurarvi
+che la chiave sia valida.
+
+Come mantenere il Web of Trust va oltre gli scopi di questo documento,
+semplicemente perché farlo come si deve richiede sia sforzi che perseveranza
+che tendono ad andare oltre al livello di interesse della maggior parte degli
+esseri umani. Qui di seguito alcuni rapidi suggerimenti per aiutarvi a ridurre
+il rischio di importare chiavi maligne.
+
+Primo, diciamo che avete provato ad eseguire ``git verify-tag`` ma restituisce
+un errore dicendo che la chiave non è stata trovata::
+
+    $ git verify-tag sunxi-fixes-for-4.15-2
+    gpg: Signature made Sun 07 Jan 2018 10:51:55 PM EST
+    gpg:                using RSA key DA73759BF8619E484E5A3B47389A54219C0F2430
+    gpg:                issuer "wens@...org"
+    gpg: Can't check signature: No public key
+
+Cerchiamo nel keyserver per maggiori informazioni sull'impronta digitale
+della chiave (l'impronta digitale, probabilmente, appartiene ad una
+sottochiave, dunque non possiamo usarla direttamente senza trovare prima
+l'ID della chiave primaria associata ad essa)::
+
+    $ gpg --search DA73759BF8619E484E5A3B47389A54219C0F2430
+    gpg: data source: hkp://keys.gnupg.net
+    (1) Chen-Yu Tsai <wens@...org>
+          4096 bit RSA key C94035C21B4F2AEB, created: 2017-03-14, expires: 2019-03-15
+    Keys 1-1 of 1 for "DA73759BF8619E484E5A3B47389A54219C0F2430".  Enter number(s), N)ext, or Q)uit > q
+
+Localizzate l'ID della chiave primaria, nel nostro esempio
+``C94035C21B4F2AEB``. Ora visualizzate le chiavi di Linus Torvalds
+che avete nel vostro portachiavi::
+
+    $ gpg --list-key torvalds@kernel.org
+    pub   rsa2048 2011-09-20 [SC]
+          ABAF11C65A2970B130ABE3C479BE3E4300411886
+    uid           [ unknown] Linus Torvalds <torvalds@kernel.org>
+    sub   rsa2048 2011-09-20 [E]
+
+Poi, aprite il `PGP pathfinder`_. Nel campo "From", incollate l'impronta
+digitale della chiave di Linus Torvalds che si vede nell'output qui sopra.
+Nel campo "to", incollate il key-id della chiave sconosciuta che avete
+trovato con ``gpg --search``, e poi verificare il risultato:
+
+- `Finding paths to Linus`_
+
+Se trovate un paio di percorsi affidabili è un buon segno circa la validità
+della chiave. Ora, potete aggiungerla al vostro portachiavi dal keyserver::
+
+    $ gpg --recv-key C94035C21B4F2AEB
+
+Questa procedura non è perfetta, e ovviamente state riponendo la vostra
+fiducia nell'amministratore del servizio *PGP Pathfinder* sperando che non
+sia malintenzionato (infatti, questo va contro :ref:`it_devs_not_infra`).
+Tuttavia, se mantenete con cura la vostra rete di fiducia sarà un deciso
+miglioramento rispetto alla cieca fiducia nei keyserver.

-    TODO ancora da tradurre
+ - Ovviamente dev'essere corretta e verificata.
+ - Non dev'essere più grande di 100 righe, incluso il contesto.
+ - Deve correggere una cosa sola.

+
+
+Procedura per sottomettere patch per i sorgenti -stable
+-------------------------------------------------------
+
+ - Se la patch contiene modifiche a dei file nelle cartelle net/ o drivers/net,
+   allora seguite le linee guida descritte in
+   :ref:`Documentation/translation/it_IT/networking/netdev-FAQ.rst <it_netdev-FAQ>`;
+   ma solo dopo aver verificato al seguente indirizzo che la patch non sia
+   già in coda:
+   https://patchwork.ozlabs.org/bundle/davem/stable/?series=&submitter=&state=*&q=&archive=
+ - Una patch di sicurezza non dovrebbero essere gestite (solamente) dal processo
+   di revisione -stable, ma dovrebbe seguire le procedure descritte in
+   :ref:`Documentation/translations/it_IT/admin-guide/security-bugs.rst <it_securitybugs>`.
+
+
+Per tutte le altre sottomissioni, scegliere una delle seguenti procedure
+------------------------------------------------------------------------
+
+.. _it_option_1:
+
+Opzione 1
+*********
+
+Per far sì che una patch venga automaticamente inclusa nei sorgenti stabili,
+aggiungete l'etichetta
+
+.. code-block:: none
+
+     Cc: stable@vger.kernel.org
+
+nell'area dedicata alla firme. Una volta che la patch è stata inclusa, verrà
+applicata anche sui sorgenti stabili senza che l'autore o il manutentore
+del sottosistema debba fare qualcosa.
+
+.. _it_option_2:
+
+Opzione 2
+*********
+
+Dopo che la patch è stata inclusa nei sorgenti Linux, inviate una mail a
+stable@vger.kernel.org includendo: il titolo della patch, l'identificativo
+del commit, il perché pensate che debba essere applicata, e in quale versione
+del kernel la vorreste vedere.
+
+.. _it_option_3:
+
+Opzione 3
+*********
+
+Inviata la patch, dopo aver verificato che rispetta le regole descritte in
+precedenza, a stable@vger.kernel.org.  Dovete annotare nel changelog
+l'identificativo del commit nei sorgenti principali, così come la versione
+del kernel nel quale vorreste vedere la patch.
+
+L':ref:`it_option_1` è fortemente raccomandata; è il modo più facile e usato.
+L':ref:`it_option_2` e l':ref:`it_option_3` sono più utili quando, al momento
+dell'inclusione dei sorgenti principali, si ritiene che non debbano essere
+incluse anche in quelli stabili (per esempio, perché si crede che si dovrebbero
+fare più verifiche per eventuali regressioni). L':ref:`it_option_3` è
+particolarmente utile se la patch ha bisogno di qualche modifica per essere
+applicata ad un kernel più vecchio (per esempio, perché nel frattempo l'API è
+cambiata).
+
+Notate che per l':ref:`it_option_3`, se la patch è diversa da quella nei
+sorgenti principali (per esempio perché è stato necessario un lavoro di
+adattamento) allora dev'essere ben documentata e giustificata nella descrizione
+della patch.
+
+L'identificativo del commit nei sorgenti principali dev'essere indicato sopra
+al messaggio della patch, così:
+
+.. code-block:: none
+
+    commit <sha1> upstream.
+
+In aggiunta, alcune patch inviate attraverso l':ref:`it_option_1` potrebbero
+dipendere da altre che devo essere incluse. Questa situazione può essere
+indicata nel seguente modo nell'area dedicata alle firme:
+
+.. code-block:: none
+
+     Cc: <stable@vger.kernel.org> # 3.3.x: a1f84a3: sched: Check for idle
+     Cc: <stable@vger.kernel.org> # 3.3.x: 1b9508f: sched: Rate-limit newidle
+     Cc: <stable@vger.kernel.org> # 3.3.x: fd21073: sched: Fix affinity logic
+     Cc: <stable@vger.kernel.org> # 3.3.x
+     Signed-off-by: Ingo Molnar <mingo@elte.hu>
+
+La sequenza di etichette ha il seguente significato:
+
+.. code-block:: none
+
+     git cherry-pick a1f84a3
+     git cherry-pick 1b9508f
+     git cherry-pick fd21073
+     git cherry-pick <this commit>
+
+Inoltre, alcune patch potrebbero avere dei requisiti circa la versione del
+kernel. Questo può essere indicato usando il seguente formato nell'area
+dedicata alle firme:
+
+.. code-block:: none
+
+     Cc: <stable@vger.kernel.org> # 3.3.x
+
+L'etichetta ha il seguente significato:
+
+.. code-block:: none
+
+     git cherry-pick <this commit>
+
+per ogni sorgente "-stable" che inizia con la versione indicata.
+
+Dopo la sottomissione:
+
+ - Il mittente riceverà un ACK quando la patch è stata accettata e messa in
+   coda, oppure un NAK se la patch è stata rigettata.  A seconda degli impegni
+   degli sviluppatori, questa risposta potrebbe richiedere alcuni giorni.
+ - Se accettata, la patch verrà aggiunta alla coda -stable per essere
+   revisionata dal altri sviluppatori e dal principale manutentore del
+   sottosistema.
+
+
+Ciclo di una revisione
+----------------------
+
+ - Quando i manutentori -stable decidono di fare un ciclo di revisione, le
+   patch vengono mandate al comitato per la revisione, ai manutentori soggetti
+   alle modifiche delle patch (a meno che il mittente non sia anche il
+   manutentore di quell'area del kernel) e in CC: alla lista di discussione
+   linux-kernel.
+ - La commissione per la revisione ha 48 ore per dare il proprio ACK o NACK
+   alle patch.
+ - Se una patch viene rigettata da un membro della commissione, o un membro
+   della lista linux-kernel obietta la bontà della patch, sollevando problemi
+   che i manutentori ed i membri non avevano compreso, allora la patch verrà
+   rimossa dalla coda.
+ - Alla fine del ciclo di revisione tutte le patch che hanno ricevuto l'ACK
+   verranno aggiunte per il prossimo rilascio -stable, e successivamente
+   questo nuovo rilascio verrà fatto.
+ - Le patch di sicurezza verranno accettate nei sorgenti -stable direttamente
+   dalla squadra per la sicurezza del kernel, e non passerà per il normale
+   ciclo di revisione. Contattate la suddetta squadra per maggiori dettagli
+   su questa procedura.
+
+Sorgenti
+--------
+
+ - La coda delle patch, sia quelle già applicate che in fase di revisione,
+   possono essere trovate al seguente indirizzo:
+
+	https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git
+
+ - Il rilascio definitivo, e marchiato, di tutti i kernel stabili può essere
+   trovato in rami distinti per versione al seguente indirizzo:
+
+	https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
+
+
+Comitato per la revisione
+-------------------------
+
+ - Questo comitato è fatto di sviluppatori del kernel che si sono offerti
+   volontari per questo lavoro, e pochi altri che non sono proprio volontari.

-Linux 内核代码风格
-=========================
-
-这是一个简短的文档，描述了 linux 内核的首选代码风格。代码风格是因人而异的，
-而且我不愿意把自己的观点强加给任何人，但这就像我去做任何事情都必须遵循的原则
-那样，我也希望在绝大多数事上保持这种的态度。请 (在写代码时) 至少考虑一下这里
-的代码风格。
-
-首先，我建议你打印一份 GNU 代码规范，然后不要读。烧了它，这是一个具有重大象征
-性意义的动作。
-
-不管怎样，现在我们开始：
-
-
-1) 缩进
---------------
-
-制表符是 8 个字符，所以缩进也是 8 个字符。有些异端运动试图将缩进变为 4 (甚至
-2！) 字符深，这几乎相当于尝试将圆周率的值定义为 3。
-
-理由：缩进的全部意义就在于清楚的定义一个控制块起止于何处。尤其是当你盯着你的
-屏幕连续看了 20 小时之后，你将会发现大一点的缩进会使你更容易分辨缩进。
-
-现在，有些人会抱怨 8 个字符的缩进会使代码向右边移动的太远，在 80 个字符的终端
-屏幕上就很难读这样的代码。这个问题的答案是，如果你需要 3 级以上的缩进，不管用
-何种方式你的代码已经有问题了，应该修正你的程序。
-
-简而言之，8 个字符的缩进可以让代码更容易阅读，还有一个好处是当你的函数嵌套太
-深的时候可以给你警告。留心这个警告。
-
-在 switch 语句中消除多级缩进的首选的方式是让 ``switch`` 和从属于它的 ``case``
-标签对齐于同一列，而不要 ``两次缩进`` ``case`` 标签。比如：
-
-.. code-block:: c
-
-	switch (suffix) {
-	case 'G':
-	case 'g':
-		mem <<= 30;
-		break;
-	case 'M':
-	case 'm':
-		mem <<= 20;
-		break;
-	case 'K':
-	case 'k':
-		mem <<= 10;
-		/* fall through */
-	default:
-		break;
-	}
-
-不要把多个语句放在一行里，除非你有什么东西要隐藏：
-
-.. code-block:: c
-
-	if (condition) do_this;
-	  do_something_everytime;
-
-也不要在一行里放多个赋值语句。内核代码风格超级简单。就是避免可能导致别人误读
-的表达式。
-
-除了注释、文档和 Kconfig 之外，不要使用空格来缩进，前面的例子是例外，是有意为
-之。
-
-选用一个好的编辑器，不要在行尾留空格。
-
-
-2) 把长的行和字符串打散
-------------------------------
-
-代码风格的意义就在于使用平常使用的工具来维持代码的可读性和可维护性。
-
-每一行的长度的限制是 80 列，我们强烈建议您遵守这个惯例。
-
-长于 80 列的语句要打散成有意义的片段。除非超过 80 列能显著增加可读性，并且不
-会隐藏信息。子片段要明显短于母片段，并明显靠右。这同样适用于有着很长参数列表
-的函数头。然而，绝对不要打散对用户可见的字符串，例如 printk 信息，因为这样就
-很难对它们 grep。
-
-
-3) 大括号和空格的放置
-------------------------------
-
-C 语言风格中另外一个常见问题是大括号的放置。和缩进大小不同，选择或弃用某种放
-置策略并没有多少技术上的原因，不过首选的方式，就像 Kernighan 和 Ritchie 展示
-给我们的，是把起始大括号放在行尾，而把结束大括号放在行首，所以：
-
-.. code-block:: c
-
-	if (x is true) {
-		we do y
-	}
-
-这适用于所有的非函数语句块 (if, switch, for, while, do)。比如：
-
-.. code-block:: c
-
-	switch (action) {
-	case KOBJ_ADD:
-		return "add";
-	case KOBJ_REMOVE:
-		return "remove";
-	case KOBJ_CHANGE:
-		return "change";
-	default:
-		return NULL;
-	}
-
-不过，有一个例外，那就是函数：函数的起始大括号放置于下一行的开头，所以：
-
-.. code-block:: c
-
-	int function(int x)
-	{
-		body of function
-	}
-
-全世界的异端可能会抱怨这个不一致性是... 呃... 不一致的，不过所有思维健全的人
-都知道 (a) K&R 是 **正确的** 并且 (b) K&R 是正确的。此外，不管怎样函数都是特
-殊的 (C 函数是不能嵌套的)。
-
-注意结束大括号独自占据一行，除非它后面跟着同一个语句的剩余部分，也就是 do 语
-句中的 "while" 或者 if 语句中的 "else"，像这样：
-
-.. code-block:: c
-
-	do {
-		body of do-loop
-	} while (condition);
-
-和
-
-.. code-block:: c
-
-	if (x == y) {
-		..
-	} else if (x > y) {
-		...
-	} else {
-		....
-	}
-
-理由：K&R。
-
-也请注意这种大括号的放置方式也能使空 (或者差不多空的) 行的数量最小化，同时不
-失可读性。因此，由于你的屏幕上的新行是不可再生资源 (想想 25 行的终端屏幕)，你
-将会有更多的空行来放置注释。
-
-当只有一个单独的语句的时候，不用加不必要的大括号。
-
-.. code-block:: c
-
-	if (condition)
-		action();
-
-和
-
-.. code-block:: c
-
-	if (condition)
-		do_this();
-	else
-		do_that();
-
-这并不适用于只有一个条件分支是单语句的情况；这时所有分支都要使用大括号：
-
-.. code-block:: c
-
-	if (condition) {
-		do_this();
-		do_that();
-	} else {
-		otherwise();
-	}
-
-3.1) 空格
-********************
-
-Linux 内核的空格使用方式 (主要) 取决于它是用于函数还是关键字。(大多数) 关键字
-后要加一个空格。值得注意的例外是 sizeof, typeof, alignof 和 __attribute__，这
-些关键字某些程度上看起来更像函数 (它们在 Linux 里也常常伴随小括号而使用，尽管
-在 C 里这样的小括号不是必需的，就像 ``struct fileinfo info;`` 声明过后的
-``sizeof info``)。
-
-所以在这些关键字之后放一个空格::
-
-	if, switch, case, for, do, while
-
-但是不要在 sizeof, typeof, alignof 或者 __attribute__ 这些关键字之后放空格。
-例如，
-
-.. code-block:: c
-
-	s = sizeof(struct file);
-
-不要在小括号里的表达式两侧加空格。这是一个 **反例** ：
-
-.. code-block:: c
-
-	s = sizeof( struct file );
-
-当声明指针类型或者返回指针类型的函数时， ``*`` 的首选使用方式是使之靠近变量名
-或者函数名，而不是靠近类型名。例子：
-
-.. code-block:: c
-
-	char *linux_banner;
-	unsigned long long memparse(char *ptr, char **retptr);
-	char *match_strdup(substring_t *s);
-
-在大多数二元和三元操作符两侧使用一个空格，例如下面所有这些操作符::
-
-	=  +  -  <  >  *  /  %  |  &  ^  <=  >=  ==  !=  ?  :
-
-但是一元操作符后不要加空格::
-
-	&  *  +  -  ~  !  sizeof  typeof  alignof  __attribute__  defined
-
-后缀自加和自减一元操作符前不加空格::
-
-	++  --
-
-前缀自加和自减一元操作符后不加空格::
-
-	++  --
-
-``.`` 和 ``->`` 结构体成员操作符前后不加空格。
-
-不要在行尾留空白。有些可以自动缩进的编辑器会在新行的行首加入适量的空白，然后
-你就可以直接在那一行输入代码。不过假如你最后没有在那一行输入代码，有些编辑器
-就不会移除已经加入的空白，就像你故意留下一个只有空白的行。包含行尾空白的行就
-这样产生了。
-
-当 git 发现补丁包含了行尾空白的时候会警告你，并且可以应你的要求去掉行尾空白；
-不过如果你是正在打一系列补丁，这样做会导致后面的补丁失败，因为你改变了补丁的
-上下文。
-
-
-4) 命名
-------------------------------
-
-C 是一个简朴的语言，你的命名也应该这样。和 Modula-2 和 Pascal 程序员不同，
-C 程序员不使用类似 ThisVariableIsATemporaryCounter 这样华丽的名字。C 程序员会
-称那个变量为 ``tmp`` ，这样写起来会更容易，而且至少不会令其难于理解。
-
-不过，虽然混用大小写的名字是不提倡使用的，但是全局变量还是需要一个具描述性的
-名字。称一个全局函数为 ``foo`` 是一个难以饶恕的错误。
-
-全局变量 (只有当你 **真正** 需要它们的时候再用它) 需要有一个具描述性的名字，就
-像全局函数。如果你有一个可以计算活动用户数量的函数，你应该叫它
-``count_active_users()`` 或者类似的名字，你不应该叫它 ``cntuser()`` 。
-
-在函数名中包含函数类型 (所谓的匈牙利命名法) 是脑子出了问题——编译器知道那些类
-型而且能够检查那些类型，这样做只能把程序员弄糊涂了。难怪微软总是制造出有问题
-的程序。
-
-本地变量名应该简短，而且能够表达相关的含义。如果你有一些随机的整数型的循环计
-数器，它应该被称为 ``i`` 。叫它 ``loop_counter`` 并无益处，如果它没有被误解的
-可能的话。类似的， ``tmp`` 可以用来称呼任意类型的临时变量。
-
-如果你怕混淆了你的本地变量名，你就遇到另一个问题了，叫做函数增长荷尔蒙失衡综
-合症。请看第六章 (函数)。
-
-
-5) Typedef
------------
-
-不要使用类似 ``vps_t`` 之类的东西。
-
-对结构体和指针使用 typedef 是一个 **错误** 。当你在代码里看到：
-
-.. code-block:: c
-
-	vps_t a;
-
-这代表什么意思呢？
-
-相反，如果是这样
-
-.. code-block:: c
-
-	struct virtual_container *a;
-
-你就知道 ``a`` 是什么了。
-
-很多人认为 typedef ``能提高可读性`` 。实际不是这样的。它们只在下列情况下有用：
-
- (a) 完全不透明的对象 (这种情况下要主动使用 typedef 来 **隐藏** 这个对象实际上
-     是什么)。
-
-     例如： ``pte_t`` 等不透明对象，你只能用合适的访问函数来访问它们。
-
-     .. note::
-
-       不透明性和 "访问函数" 本身是不好的。我们使用 pte_t 等类型的原因在于真
-       的是完全没有任何共用的可访问信息。
-
- (b) 清楚的整数类型，如此，这层抽象就可以 **帮助** 消除到底是 ``int`` 还是
-     ``long`` 的混淆。
-
-     u8/u16/u32 是完全没有问题的 typedef，不过它们更符合类别 (d) 而不是这里。
-
-     .. note::
-
-       要这样做，必须事出有因。如果某个变量是 ``unsigned long`` ，那么没有必要
-
-	typedef unsigned long myflags_t;
-
-     不过如果有一个明确的原因，比如它在某种情况下可能会是一个 ``unsigned int``
-     而在其他情况下可能为 ``unsigned long`` ，那么就不要犹豫，请务必使用
-     typedef。
-
- (c) 当你使用 sparse 按字面的创建一个 **新** 类型来做类型检查的时候。
-
- (d) 和标准 C99 类型相同的类型，在某些例外的情况下。
-
-     虽然让眼睛和脑筋来适应新的标准类型比如 ``uint32_t`` 不需要花很多时间，可
-     是有些人仍然拒绝使用它们。
-
-     因此，Linux 特有的等同于标准类型的 ``u8/u16/u32/u64`` 类型和它们的有符号
-     类型是被允许的——尽管在你自己的新代码中，它们不是强制要求要使用的。
-
-     当编辑已经使用了某个类型集的已有代码时，你应该遵循那些代码中已经做出的选
-     择。
-
- (e) 可以在用户空间安全使用的类型。
-
-     在某些用户空间可见的结构体里，我们不能要求 C99 类型而且不能用上面提到的
-     ``u32`` 类型。因此，我们在与用户空间共享的所有结构体中使用 __u32 和类似
-     的类型。
-
-可能还有其他的情况，不过基本的规则是 **永远不要** 使用 typedef，除非你可以明
-确的应用上述某个规则中的一个。
-
-总的来说，如果一个指针或者一个结构体里的元素可以合理的被直接访问到，那么它们
-就不应该是一个 typedef。
-
-
-6) 函数
-------------------------------
-
-函数应该简短而漂亮，并且只完成一件事情。函数应该可以一屏或者两屏显示完 (我们
-都知道 ISO/ANSI 屏幕大小是 80x24)，只做一件事情，而且把它做好。
-
-一个函数的最大长度是和该函数的复杂度和缩进级数成反比的。所以，如果你有一个理
-论上很简单的只有一个很长 (但是简单) 的 case 语句的函数，而且你需要在每个 case
-里做很多很小的事情，这样的函数尽管很长，但也是可以的。
-
-不过，如果你有一个复杂的函数，而且你怀疑一个天分不是很高的高中一年级学生可能
-甚至搞不清楚这个函数的目的，你应该严格遵守前面提到的长度限制。使用辅助函数，
-并为之取个具描述性的名字 (如果你觉得它们的性能很重要的话，可以让编译器内联它
-们，这样的效果往往会比你写一个复杂函数的效果要好。)
-
-函数的另外一个衡量标准是本地变量的数量。此数量不应超过 5－10 个，否则你的函数
-就有问题了。重新考虑一下你的函数，把它分拆成更小的函数。人的大脑一般可以轻松
-的同时跟踪 7 个不同的事物，如果再增多的话，就会糊涂了。即便你聪颖过人，你也可
-能会记不清你 2 个星期前做过的事情。
-
-在源文件里，使用空行隔开不同的函数。如果该函数需要被导出，它的 **EXPORT** 宏
-应该紧贴在它的结束大括号之下。比如：
-
-.. code-block:: c
-
-	int system_is_up(void)
-	{
-		return system_state == SYSTEM_RUNNING;
-	}
-	EXPORT_SYMBOL(system_is_up);
-
-在函数原型中，包含函数名和它们的数据类型。虽然 C 语言里没有这样的要求，在
-Linux 里这是提倡的做法，因为这样可以很简单的给读者提供更多的有价值的信息。
-
-
-7) 集中的函数退出途径
-------------------------------
-
-虽然被某些人声称已经过时，但是 goto 语句的等价物还是经常被编译器所使用，具体
-形式是无条件跳转指令。
-
-当一个函数从多个位置退出，并且需要做一些类似清理的常见操作时，goto 语句就很方
-便了。如果并不需要清理操作，那么直接 return 即可。
-
-选择一个能够说明 goto 行为或它为何存在的标签名。如果 goto 要释放 ``buffer``,
-一个不错的名字可以是 ``out_free_buffer:`` 。别去使用像 ``err1:`` 和 ``err2:``
-这样的GW_BASIC 名称，因为一旦你添加或删除了 (函数的) 退出路径，你就必须对它们
-重新编号，这样会难以去检验正确性。
-
-使用 goto 的理由是：
-
-- 无条件语句容易理解和跟踪
-- 嵌套程度减小
-- 可以避免由于修改时忘记更新个别的退出点而导致错误
-- 让编译器省去删除冗余代码的工作 ;)
-
-.. code-block:: c
-
-	int fun(int a)
-	{
-		int result = 0;
-		char *buffer;
-
-		buffer = kmalloc(SIZE, GFP_KERNEL);
-		if (!buffer)
-			return -ENOMEM;
-
-		if (condition1) {
-			while (loop1) {
-				...
-			}
-			result = 1;
-			goto out_free_buffer;
-		}
-		...
-	out_free_buffer:
-		kfree(buffer);
-		return result;
-	}
-
-一个需要注意的常见错误是 ``一个 err 错误`` ，就像这样：
-
-.. code-block:: c
-
-	err:
-		kfree(foo->bar);
-		kfree(foo);
-		return ret;
-
-这段代码的错误是，在某些退出路径上 ``foo`` 是 NULL。通常情况下，通过把它分离
-成两个错误标签 ``err_free_bar:`` 和 ``err_free_foo:`` 来修复这个错误：
-
-.. code-block:: c
-
-	 err_free_bar:
-		kfree(foo->bar);
-	 err_free_foo:
-		kfree(foo);
-		return ret;
-
-理想情况下，你应该模拟错误来测试所有退出路径。
-
-
-8) 注释
-------------------------------
-
-注释是好的，不过有过度注释的危险。永远不要在注释里解释你的代码是如何运作的：
-更好的做法是让别人一看你的代码就可以明白，解释写的很差的代码是浪费时间。
-
-一般的，你想要你的注释告诉别人你的代码做了什么，而不是怎么做的。也请你不要把
-注释放在一个函数体内部：如果函数复杂到你需要独立的注释其中的一部分，你很可能
-需要回到第六章看一看。你可以做一些小注释来注明或警告某些很聪明 (或者槽糕) 的
-做法，但不要加太多。你应该做的，是把注释放在函数的头部，告诉人们它做了什么，
-也可以加上它做这些事情的原因。
-
-当注释内核 API 函数时，请使用 kernel-doc 格式。请看
-Documentation/doc-guide/ 和 scripts/kernel-doc 以获得详细信息。
-
-长 (多行) 注释的首选风格是：
-
-.. code-block:: c
-
-	/*
-	 * This is the preferred style for multi-line
-	 * comments in the Linux kernel source code.
-	 * Please use it consistently.
-	 *
-	 * Description:  A column of asterisks on the left side,
-	 * with beginning and ending almost-blank lines.
-	 */
-
-对于在 net/ 和 drivers/net/ 的文件，首选的长 (多行) 注释风格有些不同。
-
-.. code-block:: c
-
-	/* The preferred comment style for files in net/ and drivers/net
-	 * looks like this.
-	 *
-	 * It is nearly the same as the generally preferred comment style,
-	 * but there is no initial almost-blank line.
-	 */
-
-注释数据也是很重要的，不管是基本类型还是衍生类型。为了方便实现这一点，每一行
-应只声明一个数据 (不要使用逗号来一次声明多个数据)。这样你就有空间来为每个数据
-写一段小注释来解释它们的用途了。
-
-
-9) 你已经把事情弄糟了
-------------------------------
-
-这没什么，我们都是这样。可能你的使用了很长时间 Unix 的朋友已经告诉你
-``GNU emacs`` 能自动帮你格式化 C 源代码，而且你也注意到了，确实是这样，不过它
-所使用的默认值和我们想要的相去甚远 (实际上，甚至比随机打的还要差——无数个猴子
-在 GNU emacs 里打字永远不会创造出一个好程序) (译注：Infinite Monkey Theorem)
-
-所以你要么放弃 GNU emacs，要么改变它让它使用更合理的设定。要采用后一个方案，
-你可以把下面这段粘贴到你的 .emacs 文件里。
-
-.. code-block:: none
-
-  (defun c-lineup-arglist-tabs-only (ignored)
-    "Line up argument lists by tabs, not spaces"
-    (let* ((anchor (c-langelem-pos c-syntactic-element))
-           (column (c-langelem-2nd-pos c-syntactic-element))
-           (offset (- (1+ column) anchor))
-           (steps (floor offset c-basic-offset)))
-      (* (max steps 1)
-         c-basic-offset)))
-
-  (dir-locals-set-class-variables
-   'linux-kernel
-   '((c-mode . (
-          (c-basic-offset . 8)
-          (c-label-minimum-indentation . 0)
-          (c-offsets-alist . (
-                  (arglist-close         . c-lineup-arglist-tabs-only)
-                  (arglist-cont-nonempty .
-		      (c-lineup-gcc-asm-reg c-lineup-arglist-tabs-only))
-                  (arglist-intro         . +)
-                  (brace-list-intro      . +)
-                  (c                     . c-lineup-C-comments)
-                  (case-label            . 0)
-                  (comment-intro         . c-lineup-comment)
-                  (cpp-define-intro      . +)
-                  (cpp-macro             . -1000)
-                  (cpp-macro-cont        . +)
-                  (defun-block-intro     . +)
-                  (else-clause           . 0)
-                  (func-decl-cont        . +)
-                  (inclass               . +)
-                  (inher-cont            . c-lineup-multi-inher)
-                  (knr-argdecl-intro     . 0)
-                  (label                 . -1000)
-                  (statement             . 0)
-                  (statement-block-intro . +)
-                  (statement-case-intro  . +)
-                  (statement-cont        . +)
-                  (substatement          . +)
-                  ))
-          (indent-tabs-mode . t)
-          (show-trailing-whitespace . t)
-          ))))
-
-  (dir-locals-set-directory-class
-   (expand-file-name "~/src/linux-trees")
-   'linux-kernel)
-
-这会让 emacs 在 ``~/src/linux-trees`` 下的 C 源文件获得更好的内核代码风格。
-
-不过就算你尝试让 emacs 正确的格式化代码失败了，也并不意味着你失去了一切：还可
-以用 ``indent`` 。
-
-不过，GNU indent 也有和 GNU emacs 一样有问题的设定，所以你需要给它一些命令选
-项。不过，这还不算太糟糕，因为就算是 GNU indent 的作者也认同 K&R 的权威性
-(GNU 的人并不是坏人，他们只是在这个问题上被严重的误导了)，所以你只要给 indent
-指定选项 ``-kr -i8`` (代表 ``K&R，8 字符缩进``)，或使用 ``scripts/Lindent``
-这样就可以以最时髦的方式缩进源代码。
-
-``indent`` 有很多选项，特别是重新格式化注释的时候，你可能需要看一下它的手册。
-不过记住： ``indent`` 不能修正坏的编程习惯。
-
-
-10) Kconfig 配置文件
-------------------------------
-
-对于遍布源码树的所有 Kconfig* 配置文件来说，它们缩进方式有所不同。紧挨着
-``config`` 定义的行，用一个制表符缩进，然而 help 信息的缩进则额外增加 2 个空
-格。举个例子::
-
-  config AUDIT
-	bool "Auditing support"
-	depends on NET
-	help
-	  Enable auditing infrastructure that can be used with another
-	  kernel subsystem, such as SELinux (which requires this for
-	  logging of avc messages output).  Does not do system-call
-	  auditing without CONFIG_AUDITSYSCALL.
-
-而那些危险的功能 (比如某些文件系统的写支持) 应该在它们的提示字符串里显著的声
-明这一点::
-
-  config ADFS_FS_RW
-	bool "ADFS write support (DANGEROUS)"
-	depends on ADFS_FS
-	...
-
-要查看配置文件的完整文档，请看 Documentation/kbuild/kconfig-language.txt。
-
-
-11) 数据结构
-------------------------------
-
-如果一个数据结构，在创建和销毁它的单线执行环境之外可见，那么它必须要有一个引
-用计数器。内核里没有垃圾收集 (并且内核之外的垃圾收集慢且效率低下)，这意味着你
-绝对需要记录你对这种数据结构的使用情况。
-
-引用计数意味着你能够避免上锁，并且允许多个用户并行访问这个数据结构——而不需要
-担心这个数据结构仅仅因为暂时不被使用就消失了，那些用户可能不过是沉睡了一阵或
-者做了一些其他事情而已。
-
-注意上锁 **不能** 取代引用计数。上锁是为了保持数据结构的一致性，而引用计数是一
-个内存管理技巧。通常二者都需要，不要把两个搞混了。
-
-很多数据结构实际上有 2 级引用计数，它们通常有不同 ``类`` 的用户。子类计数器统
-计子类用户的数量，每当子类计数器减至零时，全局计数器减一。
-
-这种 ``多级引用计数`` 的例子可以在内存管理 (``struct mm_struct``: mm_users 和
-mm_count)，和文件系统 (``struct super_block``: s_count 和 s_active) 中找到。
-
-记住：如果另一个执行线索可以找到你的数据结构，但这个数据结构没有引用计数器，
-这里几乎肯定是一个 bug。
-
-
-12) 宏，枚举和RTL
-------------------------------
-
-用于定义常量的宏的名字及枚举里的标签需要大写。
-
-.. code-block:: c
-
-	#define CONSTANT 0x12345
-
-在定义几个相关的常量时，最好用枚举。
-
-宏的名字请用大写字母，不过形如函数的宏的名字可以用小写字母。
-
-一般的，如果能写成内联函数就不要写成像函数的宏。
-
-含有多个语句的宏应该被包含在一个 do-while 代码块里：
-
-.. code-block:: c
-
-	#define macrofun(a, b, c)			\
-		do {					\
-			if (a == 5)			\
-				do_this(b, c);		\
-		} while (0)
-
-使用宏的时候应避免的事情：
-
-1) 影响控制流程的宏：
-
-.. code-block:: c
-
-	#define FOO(x)					\
-		do {					\
-			if (blah(x) < 0)		\
-				return -EBUGGERED;	\
-		} while (0)
-
-**非常** 不好。它看起来像一个函数，不过却能导致 ``调用`` 它的函数退出；不要打
-乱读者大脑里的语法分析器。
-
-2) 依赖于一个固定名字的本地变量的宏：
-
-.. code-block:: c
-
-	#define FOO(val) bar(index, val)
-
-可能看起来像是个不错的东西，不过它非常容易把读代码的人搞糊涂，而且容易导致看起
-来不相关的改动带来错误。
-
-3) 作为左值的带参数的宏： FOO(x) = y；如果有人把 FOO 变成一个内联函数的话，这
-   种用法就会出错了。
-
-4) 忘记了优先级：使用表达式定义常量的宏必须将表达式置于一对小括号之内。带参数
-   的宏也要注意此类问题。
-
-.. code-block:: c
-
-	#define CONSTANT 0x4000
-	#define CONSTEXP (CONSTANT | 3)
-
-5) 在宏里定义类似函数的本地变量时命名冲突：
-
-.. code-block:: c
-
-	#define FOO(x)				\
-	({					\
-		typeof(x) ret;			\
-		ret = calc_ret(x);		\
-		(ret);				\
-	})
-
-ret 是本地变量的通用名字 - __foo_ret 更不容易与一个已存在的变量冲突。
-
-cpp 手册对宏的讲解很详细。gcc internals 手册也详细讲解了 RTL，内核里的汇编语
-言经常用到它。
-
-
-13) 打印内核消息
-------------------------------
-
-内核开发者应该是受过良好教育的。请一定注意内核信息的拼写，以给人以好的印象。
-不要用不规范的单词比如 ``dont``，而要用 ``do not`` 或者 ``don't`` 。保证这些信
-息简单明了,无歧义。
-
-内核信息不必以英文句号结束。
-
-在小括号里打印数字 (%d) 没有任何价值，应该避免这样做。
-
-<linux/device.h> 里有一些驱动模型诊断宏，你应该使用它们，以确保信息对应于正确
-的设备和驱动，并且被标记了正确的消息级别。这些宏有：dev_err(), dev_warn(),
-dev_info() 等等。对于那些不和某个特定设备相关连的信息，<linux/printk.h> 定义
-了 pr_notice(), pr_info(), pr_warn(), pr_err() 和其他。
-
-写出好的调试信息可以是一个很大的挑战；一旦你写出后，这些信息在远程除错时能提
-供极大的帮助。然而打印调试信息的处理方式同打印非调试信息不同。其他 pr_XXX()
-函数能无条件地打印，pr_debug() 却不；默认情况下它不会被编译，除非定义了 DEBUG
-或设定了 CONFIG_DYNAMIC_DEBUG。实际这同样是为了 dev_dbg()，一个相关约定是在一
-个已经开启了 DEBUG 时，使用 VERBOSE_DEBUG 来添加 dev_vdbg()。
-
-许多子系统拥有 Kconfig 调试选项来开启 -DDEBUG 在对应的 Makefile 里面；在其他
-情况下，特殊文件使用 #define DEBUG。当一条调试信息需要被无条件打印时，例如，
-如果已经包含一个调试相关的 #ifdef 条件，printk(KERN_DEBUG ...) 就可被使用。
-
-
-14) 分配内存
-------------------------------
-
-内核提供了下面的一般用途的内存分配函数：
-kmalloc(), kzalloc(), kmalloc_array(), kcalloc(), vmalloc() 和 vzalloc()。
-请参考 API 文档以获取有关它们的详细信息。
-
-传递结构体大小的首选形式是这样的：
-
-.. code-block:: c
-
-	p = kmalloc(sizeof(*p), ...);
-
-另外一种传递方式中，sizeof 的操作数是结构体的名字，这样会降低可读性，并且可能
-会引入 bug。有可能指针变量类型被改变时，而对应的传递给内存分配函数的 sizeof
-的结果不变。
-
-强制转换一个 void 指针返回值是多余的。C 语言本身保证了从 void 指针到其他任何
-指针类型的转换是没有问题的。
-
-分配一个数组的首选形式是这样的：
-
-.. code-block:: c
-
-	p = kmalloc_array(n, sizeof(...), ...);
-
-分配一个零长数组的首选形式是这样的：
-
-.. code-block:: c
-
-	p = kcalloc(n, sizeof(...), ...);
-
-两种形式检查分配大小 n * sizeof(...) 的溢出，如果溢出返回 NULL。
-
-
-15) 内联弊病
-------------------------------
-
-有一个常见的误解是 ``内联`` 是 gcc 提供的可以让代码运行更快的一个选项。虽然使
-用内联函数有时候是恰当的 (比如作为一种替代宏的方式，请看第十二章)，不过很多情
-况下不是这样。inline 的过度使用会使内核变大，从而使整个系统运行速度变慢。
-因为体积大内核会占用更多的指令高速缓存，而且会导致 pagecache 的可用内存减少。
-想象一下，一次 pagecache 未命中就会导致一次磁盘寻址，将耗时 5 毫秒。5 毫秒的
-时间内 CPU 能执行很多很多指令。
-
-一个基本的原则是如果一个函数有 3 行以上，就不要把它变成内联函数。这个原则的一
-个例外是，如果你知道某个参数是一个编译时常量，而且因为这个常量你确定编译器在
-编译时能优化掉你的函数的大部分代码，那仍然可以给它加上 inline 关键字。
-kmalloc() 内联函数就是一个很好的例子。
-
-人们经常主张给 static 的而且只用了一次的函数加上 inline，如此不会有任何损失，
-因为没有什么好权衡的。虽然从技术上说这是正确的，但是实际上这种情况下即使不加
-inline gcc 也可以自动使其内联。而且其他用户可能会要求移除 inline，由此而来的
-争论会抵消 inline 自身的潜在价值，得不偿失。
-
-
-16) 函数返回值及命名
-------------------------------
-
-函数可以返回多种不同类型的值，最常见的一种是表明函数执行成功或者失败的值。这样
-的一个值可以表示为一个错误代码整数 (-Exxx＝失败，0＝成功) 或者一个 ``成功``
-布尔值 (0＝失败，非0＝成功)。
-
-混合使用这两种表达方式是难于发现的 bug 的来源。如果 C 语言本身严格区分整形和
-布尔型变量，那么编译器就能够帮我们发现这些错误... 不过 C 语言不区分。为了避免
-产生这种 bug，请遵循下面的惯例::
-
-	如果函数的名字是一个动作或者强制性的命令，那么这个函数应该返回错误代
-	码整数。如果是一个判断，那么函数应该返回一个 "成功" 布尔值。
-
-比如， ``add work`` 是一个命令，所以 add_work() 在成功时返回 0，在失败时返回
--EBUSY。类似的，因为 ``PCI device present`` 是一个判断，所以 pci_dev_present()
-在成功找到一个匹配的设备时应该返回 1，如果找不到时应该返回 0。
-
-所有 EXPORTed 函数都必须遵守这个惯例，所有的公共函数也都应该如此。私有
-(static) 函数不需要如此，但是我们也推荐这样做。
-
-返回值是实际计算结果而不是计算是否成功的标志的函数不受此惯例的限制。一般的，
-他们通过返回一些正常值范围之外的结果来表示出错。典型的例子是返回指针的函数，
-他们使用 NULL 或者 ERR_PTR 机制来报告错误。
-
-
-17) 不要重新发明内核宏
-------------------------------
-
-头文件 include/linux/kernel.h 包含了一些宏，你应该使用它们，而不要自己写一些
-它们的变种。比如，如果你需要计算一个数组的长度，使用这个宏
-
-.. code-block:: c
-
-	#define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))
-
-类似的，如果你要计算某结构体成员的大小，使用
-
-.. code-block:: c
-
-	#define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f))
-
-还有可以做严格的类型检查的 min() 和 max() 宏，如果你需要可以使用它们。你可以
-自己看看那个头文件里还定义了什么你可以拿来用的东西，如果有定义的话，你就不应
-在你的代码里自己重新定义。
-
-
-18) 编辑器模式行和其他需要罗嗦的事情
---------------------------------------------------
-
-有一些编辑器可以解释嵌入在源文件里的由一些特殊标记标明的配置信息。比如，emacs
-能够解释被标记成这样的行：
-
-.. code-block:: c
-
-	-*- mode: c -*-
-
-或者这样的：
-
-.. code-block:: c
-
-	/*
-	Local Variables:
-	compile-command: "gcc -DMAGIC_DEBUG_FLAG foo.c"
-	End:
-	*/
-
-Vim 能够解释这样的标记：
-
-.. code-block:: c
-
-	/* vim:set sw=8 noet */
-
-不要在源代码中包含任何这样的内容。每个人都有他自己的编辑器配置，你的源文件不
-应该覆盖别人的配置。这包括有关缩进和模式配置的标记。人们可以使用他们自己定制
-的模式，或者使用其他可以产生正确的缩进的巧妙方法。
-
-
-19) 内联汇编
-------------------------------
-
-在特定架构的代码中，你可能需要内联汇编与 CPU 和平台相关功能连接。需要这么做时
-就不要犹豫。然而，当 C 可以完成工作时，不要平白无故地使用内联汇编。在可能的情
-况下，你可以并且应该用 C 和硬件沟通。
-
-请考虑去写捆绑通用位元 (wrap common bits) 的内联汇编的简单辅助函数，别去重复
-地写下只有细微差异内联汇编。记住内联汇编可以使用 C 参数。
-
-大型，有一定复杂度的汇编函数应该放在 .S 文件内，用相应的 C 原型定义在 C 头文
-件中。汇编函数的 C 原型应该使用 ``asmlinkage`` 。
-
-你可能需要把汇编语句标记为 volatile，用来阻止 GCC 在没发现任何副作用后就把它
-移除了。你不必总是这样做，尽管，这不必要的举动会限制优化。
-
-在写一个包含多条指令的单个内联汇编语句时，把每条指令用引号分割而且各占一行，
-除了最后一条指令外，在每个指令结尾加上 \n\t，让汇编输出时可以正确地缩进下一条
-指令：
-
-.. code-block:: c
-
-	asm ("magic %reg1, #42\n\t"
-	     "more_magic %reg2, %reg3"
-	     : /* outputs */ : /* inputs */ : /* clobbers */);
-
-
-20) 条件编译
-------------------------------
-
-只要可能，就不要在 .c 文件里面使用预处理条件 (#if, #ifdef)；这样做让代码更难
-阅读并且更难去跟踪逻辑。替代方案是，在头文件中用预处理条件提供给那些 .c 文件
-使用，再给 #else 提供一个空桩 (no-op stub) 版本，然后在 .c 文件内无条件地调用
-那些 (定义在头文件内的) 函数。这样做，编译器会避免为桩函数 (stub) 的调用生成
-任何代码，产生的结果是相同的，但逻辑将更加清晰。
-
-最好倾向于编译整个函数，而不是函数的一部分或表达式的一部分。与其放一个 ifdef
-在表达式内，不如分解出部分或全部表达式，放进一个单独的辅助函数，并应用预处理
-条件到这个辅助函数内。
-
-如果你有一个在特定配置中，可能变成未使用的函数或变量，编译器会警告它定义了但
-未使用，把它标记为 __maybe_unused 而不是将它包含在一个预处理条件中。(然而，如
-果一个函数或变量总是未使用，就直接删除它。)
-
-在代码中，尽可能地使用 IS_ENABLED 宏来转化某个 Kconfig 标记为 C 的布尔
-表达式，并在一般的 C 条件中使用它：
-
-.. code-block:: c
-
-	if (IS_ENABLED(CONFIG_SOMETHING)) {
-		...
-	}
-
-编译器会做常量折叠，然后就像使用 #ifdef 那样去包含或排除代码块，所以这不会带
-来任何运行时开销。然而，这种方法依旧允许 C 编译器查看块内的代码，并检查它的正
-确性 (语法，类型，符号引用，等等)。因此，如果条件不满足，代码块内的引用符号就
-不存在时，你还是必须去用 #ifdef。
-
-在任何有意义的 #if 或 #ifdef 块的末尾 (超过几行的)，在 #endif 同一行的后面写下
-注解，注释这个条件表达式。例如：
-
-.. code-block:: c
-
-	#ifdef CONFIG_SOMETHING
-	...
-	#endif /* CONFIG_SOMETHING */

-Linux邮件客户端配置信息
-======================================================================
-
-普通配置
-----------------------------------------------------------------------
-Linux内核补丁是通过邮件被提交的，最好把补丁作为邮件体的内嵌文本。有些维护者
-接收附件，但是附件的内容格式应该是"text/plain"。然而，附件一般是不赞成的，
-因为这会使补丁的引用部分在评论过程中变的很困难。
-
-用来发送Linux内核补丁的邮件客户端在发送补丁时应该处于文本的原始状态。例如，
-他们不能改变或者删除制表符或者空格，甚至是在每一行的开头或者结尾。
-
-不要通过"format=flowed"模式发送补丁。这样会引起不可预期以及有害的断行。
-
-不要让你的邮件客户端进行自动换行。这样也会破坏你的补丁。
-
-邮件客户端不能改变文本的字符集编码方式。要发送的补丁只能是ASCII或者UTF-8编码方式，
-如果你使用UTF-8编码方式发送邮件，那么你将会避免一些可能发生的字符集问题。
-
-邮件客户端应该形成并且保持 References: 或者 In-Reply-To: 标题，那么
-邮件话题就不会中断。
-
-复制粘帖(或者剪贴粘帖)通常不能用于补丁，因为制表符会转换为空格。使用xclipboard, xclip
-或者xcutsel也许可以，但是最好测试一下或者避免使用复制粘帖。
-
-不要在使用PGP/GPG署名的邮件中包含补丁。这样会使得很多脚本不能读取和适用于你的补丁。
-（这个问题应该是可以修复的）
-
-在给内核邮件列表发送补丁之前，给自己发送一个补丁是个不错的主意，保存接收到的
-邮件，将补丁用'patch'命令打上，如果成功了，再给内核邮件列表发送。
-
-
-一些邮件客户端提示
-----------------------------------------------------------------------
-这里给出一些详细的MUA配置提示，可以用于给Linux内核发送补丁。这些并不意味是
-所有的软件包配置总结。
-
-说明：
-TUI = 以文本为基础的用户接口
-GUI = 图形界面用户接口
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Alpine (TUI)
-
-配置选项：
-在"Sending Preferences"部分：
-
-- "Do Not Send Flowed Text"必须开启
-- "Strip Whitespace Before Sending"必须关闭
-
-当写邮件时，光标应该放在补丁会出现的地方，然后按下CTRL-R组合键，使指定的
-补丁文件嵌入到邮件中。
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Evolution (GUI)
-
-一些开发者成功的使用它发送补丁
-
-当选择邮件选项：Preformat
-  从Format->Heading->Preformatted (Ctrl-7)或者工具栏
-
-然后使用：
-  Insert->Text File... (Alt-n x)插入补丁文件。
-
-你还可以"diff -Nru old.c new.c | xclip"，选择Preformat，然后使用中间键进行粘帖。
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Kmail (GUI)
-
-一些开发者成功的使用它发送补丁。
-
-默认设置不为HTML格式是合适的；不要启用它。
-
-当书写一封邮件的时候，在选项下面不要选择自动换行。唯一的缺点就是你在邮件中输入的任何文本
-都不会被自动换行，因此你必须在发送补丁之前手动换行。最简单的方法就是启用自动换行来书写邮件，
-然后把它保存为草稿。一旦你在草稿中再次打开它，它已经全部自动换行了，那么你的邮件虽然没有
-选择自动换行，但是还不会失去已有的自动换行。
-
-在邮件的底部，插入补丁之前，放上常用的补丁定界符：三个连字号(---)。
-
-然后在"Message"菜单条目，选择插入文件，接着选取你的补丁文件。还有一个额外的选项，你可以
-通过它配置你的邮件建立工具栏菜单，还可以带上"insert file"图标。
-
-你可以安全地通过GPG标记附件，但是内嵌补丁最好不要使用GPG标记它们。作为内嵌文本的签发补丁，
-当从GPG中提取7位编码时会使他们变的更加复杂。
-
-如果你非要以附件的形式发送补丁，那么就右键点击附件，然后选中属性，突出"Suggest automatic
-display"，这样内嵌附件更容易让读者看到。
-
-当你要保存将要发送的内嵌文本补丁，你可以从消息列表窗格选择包含补丁的邮件，然后右击选择
-"save as"。你可以使用一个没有更改的包含补丁的邮件，如果它是以正确的形式组成。当你正真在它
-自己的窗口之下察看，那时没有选项可以保存邮件--已经有一个这样的bug被汇报到了kmail的bugzilla
-并且希望这将会被处理。邮件是以只针对某个用户可读写的权限被保存的，所以如果你想把邮件复制到其他地方，
-你不得不把他们的权限改为组或者整体可读。
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Lotus Notes (GUI)
-
-不要使用它。
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Mutt (TUI)
-
-很多Linux开发人员使用mutt客户端，所以证明它肯定工作的非常漂亮。
-
-Mutt不自带编辑器，所以不管你使用什么编辑器都不应该带有自动断行。大多数编辑器都带有
-一个"insert file"选项，它可以通过不改变文件内容的方式插入文件。
-
-'vim'作为mutt的编辑器：
-  set editor="vi"
-
-  如果使用xclip，敲入以下命令
-  :set paste
-  按中键之前或者shift-insert或者使用
-  :r filename
-
-如果想要把补丁作为内嵌文本。
-(a)ttach工作的很好，不带有"set paste"。
-
-配置选项：
-它应该以默认设置的形式工作。
-然而，把"send_charset"设置为"us-ascii::utf-8"也是一个不错的主意。
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Pine (TUI)
-
-Pine过去有一些空格删减问题，但是这些现在应该都被修复了。
-
-如果可以，请使用alpine(pine的继承者)
-
-配置选项：
-- 最近的版本需要消除流程文本
-- "no-strip-whitespace-before-send"选项也是需要的。
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Sylpheed (GUI)
-
-- 内嵌文本可以很好的工作（或者使用附件）。
-- 允许使用外部的编辑器。
-- 对于目录较多时非常慢。
-- 如果通过non-SSL连接，无法使用TLS SMTP授权。
-- 在组成窗口中有一个很有用的ruler bar。
-- 给地址本中添加地址就不会正确的了解显示名。
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Thunderbird (GUI)
-
-默认情况下，thunderbird很容易损坏文本，但是还有一些方法可以强制它变得更好。
-
-- 在用户帐号设置里，组成和寻址，不要选择"Compose messages in HTML format"。
-
-- 编辑你的Thunderbird配置设置来使它不要拆行使用：user_pref("mailnews.wraplength", 0);
-
-- 编辑你的Thunderbird配置设置，使它不要使用"format=flowed"格式：user_pref("mailnews.
-  send_plaintext_flowed", false);
-
-- 你需要使Thunderbird变为预先格式方式：
-  如果默认情况下你书写的是HTML格式，那不是很难。仅仅从标题栏的下拉框中选择"Preformat"格式。
-  如果默认情况下你书写的是文本格式，你不得把它改为HTML格式（仅仅作为一次性的）来书写新的消息，
-  然后强制使它回到文本格式，否则它就会拆行。要实现它，在写信的图标上使用shift键来使它变为HTML
-  格式，然后标题栏的下拉框中选择"Preformat"格式。
-
-- 允许使用外部的编辑器：
-  针对Thunderbird打补丁最简单的方法就是使用一个"external editor"扩展，然后使用你最喜欢的
-  $EDITOR来读取或者合并补丁到文本中。要实现它，可以下载并且安装这个扩展，然后添加一个使用它的
-  按键View->Toolbars->Customize...最后当你书写信息的时候仅仅点击它就可以了。
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-TkRat (GUI)
-
-可以使用它。使用"Insert file..."或者外部的编辑器。
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Gmail (Web GUI)
-
-不要使用它发送补丁。
-
-Gmail网页客户端自动地把制表符转换为空格。
-
-虽然制表符转换为空格问题可以被外部编辑器解决，同时它还会使用回车换行把每行拆分为78个字符。
-
-另一个问题是Gmail还会把任何不是ASCII的字符的信息改为base64编码。它把东西变的像欧洲人的名字。
-
-                                ###

-如何参与Linux内核开发
----------------------
-
-这是一篇将如何参与Linux内核开发的相关问题一网打尽的终极秘笈。它将指导你
-成为一名Linux内核开发者，并且学会如何同Linux内核开发社区合作。它尽可能不
-包括任何关于内核编程的技术细节，但会给你指引一条获得这些知识的正确途径。
-
-如果这篇文章中的任何内容不再适用，请给文末列出的文件维护者发送补丁。
-
-
-入门
-----
-
-你想了解如何成为一名Linux内核开发者？或者老板吩咐你“给这个设备写个Linux
-驱动程序”？这篇文章的目的就是教会你达成这些目标的全部诀窍，它将描述你需
-要经过的流程以及给出如何同内核社区合作的一些提示。它还将试图解释内核社区
-为何这样运作。
-
-Linux内核大部分是由C语言写成的，一些体系结构相关的代码用到了汇编语言。要
-参与内核开发，你必须精通C语言。除非你想为某个架构开发底层代码，否则你并
-不需要了解（任何体系结构的）汇编语言。下面列举的书籍虽然不能替代扎实的C
-语言教育和多年的开发经验，但如果需要的话，做为参考还是不错的：
- - "The C Programming Language" by Kernighan and Ritchie [Prentice Hall]
-   《C程序设计语言（第2版·新版）》（徐宝文 李志 译）[机械工业出版社]
- - "Practical C Programming" by Steve Oualline [O'Reilly]
-   《实用C语言编程（第三版）》（郭大海 译）[中国电力出版社]
- - "C:  A Reference Manual" by Harbison and Steele [Prentice Hall]
-   《C语言参考手册（原书第5版）》（邱仲潘 等译）[机械工业出版社]
-
-Linux内核使用GNU C和GNU工具链开发。虽然它遵循ISO C89标准，但也用到了一些
-标准中没有定义的扩展。内核是自给自足的C环境，不依赖于标准C库的支持，所以
-并不支持C标准中的部分定义。比如long long类型的大数除法和浮点运算就不允许
-使用。有时候确实很难弄清楚内核对工具链的要求和它所使用的扩展，不幸的是目
-前还没有明确的参考资料可以解释它们。请查阅gcc信息页（使用“info gcc”命令
-显示）获得一些这方面信息。
-
-请记住你是在学习怎么和已经存在的开发社区打交道。它由一群形形色色的人组成，
-他们对代码、风格和过程有着很高的标准。这些标准是在长期实践中总结出来的，
-适应于地理上分散的大型开发团队。它们已经被很好得整理成档，建议你在开发
-之前尽可能多的学习这些标准，而不要期望别人来适应你或者你公司的行为方式。
-
-
-法律问题
---------
-
-Linux内核源代码都是在GPL（通用公共许可证）的保护下发布的。要了解这种许可
-的细节请查看源代码主目录下的COPYING文件。如果你对它还有更深入问题请联系
-律师，而不要在Linux内核邮件组上提问。因为邮件组里的人并不是律师，不要期
-望他们的话有法律效力。
-
-对于GPL的常见问题和解答，请访问以下链接：
-	http://www.gnu.org/licenses/gpl-faq.html
-
-
-文档
-----
-
-Linux内核代码中包含有大量的文档。这些文档对于学习如何与内核社区互动有着
-不可估量的价值。当一个新的功能被加入内核，最好把解释如何使用这个功能的文
-档也放进内核。当内核的改动导致面向用户空间的接口发生变化时，最好将相关信
-息或手册页(manpages)的补丁发到mtk.manpages@gmail.com，以向手册页(manpages)
-的维护者解释这些变化。
-
-以下是内核代码中需要阅读的文档：
-  README
-    文件简要介绍了Linux内核的背景，并且描述了如何配置和编译内核。内核的
-    新用户应该从这里开始。
-
-  Documentation/process/changes.rst
-    文件给出了用来编译和使用内核所需要的最小软件包列表。
-
-  Documentation/process/coding-style.rst
-    描述Linux内核的代码风格和理由。所有新代码需要遵守这篇文档中定义的规
-    范。大多数维护者只会接收符合规定的补丁，很多人也只会帮忙检查符合风格
-    的代码。
-
-  Documentation/process/submitting-patches.rst
-  Documentation/process/submitting-drivers.rst
-    这两份文档明确描述如何创建和发送补丁，其中包括（但不仅限于)：
-       - 邮件内容
-       - 邮件格式
-       - 选择收件人
-    遵守这些规定并不能保证提交成功（因为所有补丁需要通过严格的内容和风格
-    审查），但是忽视他们几乎就意味着失败。
-
-    其他关于如何正确地生成补丁的优秀文档包括：
-    "The Perfect Patch"
-        http://www.ozlabs.org/~akpm/stuff/tpp.txt
-    "Linux kernel patch submission format"
-        http://linux.yyz.us/patch-format.html
-
-  Documentation/process/stable-api-nonsense.rst
-    论证内核为什么特意不包括稳定的内核内部API，也就是说不包括像这样的特
-    性：
-       - 子系统中间层（为了兼容性？）
-       - 在不同操作系统间易于移植的驱动程序
-       - 减缓（甚至阻止）内核代码的快速变化
-    这篇文档对于理解Linux的开发哲学至关重要。对于将开发平台从其他操作系
-    统转移到Linux的人来说也很重要。
-
-  Documentation/admin-guide/security-bugs.rst
-    如果你认为自己发现了Linux内核的安全性问题，请根据这篇文档中的步骤来
-    提醒其他内核开发者并帮助解决这个问题。
-
-  Documentation/process/management-style.rst
-    描述内核维护者的工作方法及其共有特点。这对于刚刚接触内核开发（或者对
-    它感到好奇）的人来说很重要，因为它解释了很多对于内核维护者独特行为的
-    普遍误解与迷惑。
-
-  Documentation/process/stable-kernel-rules.rst
-    解释了稳定版内核发布的规则，以及如何将改动放入这些版本的步骤。
-
-  Documentation/process/kernel-docs.rst
-    有助于内核开发的外部文档列表。如果你在内核自带的文档中没有找到你想找
-    的内容，可以查看这些文档。
-
-  Documentation/process/applying-patches.rst
-    关于补丁是什么以及如何将它打在不同内核开发分支上的好介绍
-
-内核还拥有大量从代码自动生成的文档。它包含内核内部API的全面介绍以及如何
-妥善处理加锁的规则。生成的文档会放在 Documentation/DocBook/目录下。在内
-核源码的主目录中使用以下不同命令将会分别生成PDF、Postscript、HTML和手册
-页等不同格式的文档：
-    make pdfdocs
-    make htmldocs
-
-
-如何成为内核开发者
-------------------
-如果你对Linux内核开发一无所知，你应该访问“Linux内核新手”计划：
-	http://kernelnewbies.org
-它拥有一个可以问各种最基本的内核开发问题的邮件列表（在提问之前一定要记得
-查找已往的邮件，确认是否有人已经回答过相同的问题）。它还拥有一个可以获得
-实时反馈的IRC聊天频道，以及大量对于学习Linux内核开发相当有帮助的文档。
-
-网站简要介绍了源代码组织结构、子系统划分以及目前正在进行的项目（包括内核
-中的和单独维护的）。它还提供了一些基本的帮助信息，比如如何编译内核和打补
-丁。
-
-如果你想加入内核开发社区并协助完成一些任务，却找不到从哪里开始，可以访问
-“Linux内核房管员”计划：
-	http://kernelnewbies.org/KernelJanitors
-这是极佳的起点。它提供一个相对简单的任务列表，列出内核代码中需要被重新
-整理或者改正的地方。通过和负责这个计划的开发者们一同工作，你会学到将补丁
-集成进内核的基本原理。如果还没有决定下一步要做什么的话，你还可能会得到方
-向性的指点。
-
-如果你已经有一些现成的代码想要放到内核中，但是需要一些帮助来使它们拥有正
-确的格式。请访问“内核导师”计划。这个计划就是用来帮助你完成这个目标的。它
-是一个邮件列表，地址如下：
-	http://selenic.com/mailman/listinfo/kernel-mentors
-
-在真正动手修改内核代码之前，理解要修改的代码如何运作是必需的。要达到这个
-目的，没什么办法比直接读代码更有效了（大多数花招都会有相应的注释），而且
-一些特制的工具还可以提供帮助。例如，“Linux代码交叉引用”项目就是一个值得
-特别推荐的帮助工具，它将源代码显示在有编目和索引的网页上。其中一个更新及
-时的内核源码库，可以通过以下地址访问：
-	http://sosdg.org/~coywolf/lxr/
-
-
-开发流程
---------
-
-目前Linux内核开发流程包括几个“主内核分支”和很多子系统相关的内核分支。这
-些分支包括：
-  - 2.6.x主内核源码树
-  - 2.6.x.y -stable内核源码树
-  - 2.6.x -mm内核补丁集
-  - 子系统相关的内核源码树和补丁集
-
-
-2.6.x内核主源码树
------------------
-2.6.x内核是由Linus Torvalds（Linux的创造者）亲自维护的。你可以在
-kernel.org网站的pub/linux/kernel/v2.6/目录下找到它。它的开发遵循以下步
-骤：
-  - 每当一个新版本的内核被发布，为期两周的集成窗口将被打开。在这段时间里
-    维护者可以向Linus提交大段的修改，通常这些修改已经被放到-mm内核中几个
-    星期了。提交大量修改的首选方式是使用git工具（内核的代码版本管理工具
-    ，更多的信息可以在http://git-scm.com/获取），不过使用普通补丁也是可以
-    的。
-  - 两个星期以后-rc1版本内核发布。之后只有不包含可能影响整个内核稳定性的
-    新功能的补丁才可能被接受。请注意一个全新的驱动程序（或者文件系统）有
-    可能在-rc1后被接受是因为这样的修改完全独立，不会影响其他的代码，所以
-    没有造成内核退步的风险。在-rc1以后也可以用git向Linus提交补丁，不过所
-    有的补丁需要同时被发送到相应的公众邮件列表以征询意见。
-  - 当Linus认为当前的git源码树已经达到一个合理健全的状态足以发布供人测试
-    时，一个新的-rc版本就会被发布。计划是每周都发布新的-rc版本。
-  - 这个过程一直持续下去直到内核被认为达到足够稳定的状态，持续时间大概是
-    6个星期。
-
-关于内核发布，值得一提的是Andrew Morton在linux-kernel邮件列表中如是说：
-	“没有人知道新内核何时会被发布，因为发布是根据已知bug的情况来决定
-	的，而不是根据一个事先制定好的时间表。”
-
-
-2.6.x.y -stable（稳定版）内核源码树
------------------------------------
-由4个数字组成的内核版本号说明此内核是-stable版本。它们包含基于2.6.x版本
-内核的相对较小且至关重要的修补，这些修补针对安全性问题或者严重的内核退步。
-
-这种版本的内核适用于那些期望获得最新的稳定版内核并且不想参与测试开发版或
-者实验版的用户。
-
-如果没有2.6.x.y版本内核存在，那么最新的2.6.x版本内核就相当于是当前的稳定
-版内核。
-
-2.6.x.y版本由“稳定版”小组（邮件地址<stable@vger.kernel.org>）维护，一般隔周发
-布新版本。
-
-内核源码中的Documentation/process/stable-kernel-rules.rst文件具体描述了可被稳定
-版内核接受的修改类型以及发布的流程。
-
-
-2.6.x -mm补丁集
----------------
-这是由Andrew Morton维护的试验性内核补丁集。Andrew将所有子系统的内核源码
-和补丁拼凑到一起，并且加入了大量从linux-kernel邮件列表中采集的补丁。这个
-源码树是新功能和补丁的试炼场。当补丁在-mm补丁集里证明了其价值以后Andrew
-或者相应子系统的维护者会将补丁发给Linus以便集成进主内核源码树。
-
-在将所有新补丁发给Linus以集成到主内核源码树之前，我们非常鼓励先把这些补
-丁放在-mm版内核源码树中进行测试。
-
-这些内核版本不适合在需要稳定运行的系统上运行，因为运行它们比运行任何其他
-内核分支都更具有风险。
-
-如果你想为内核开发进程提供帮助，请尝试并使用这些内核版本，并在
-linux-kernel邮件列表中提供反馈，告诉大家你遇到了问题还是一切正常。
-
-通常-mm版补丁集不光包括这些额外的试验性补丁，还包括发布时-git版主源码树
-中的改动。
-
--mm版内核没有固定的发布周期，但是通常在每两个-rc版内核发布之间都会有若干
-个-mm版内核发布（一般是1至3个）。
-
-
-子系统相关内核源码树和补丁集
-----------------------------
-相当一部分内核子系统开发者会公开他们自己的开发源码树，以便其他人能了解内
-核的不同领域正在发生的事情。如上所述，这些源码树会被集成到-mm版本内核中。
-
-下面是目前可用的一些内核源码树的列表：

-
-报告bug
--------
-
-bugzilla.kernel.org是Linux内核开发者们用来跟踪内核Bug的网站。我们鼓励用
-户在这个工具中报告找到的所有bug。如何使用内核bugzilla的细节请访问：
-	http://test.kernel.org/bugzilla/faq.html
-
-内核源码主目录中的admin-guide/reporting-bugs.rst文件里有一个很好的模板。它指导用户如何报
-告可能的内核bug以及需要提供哪些信息来帮助内核开发者们找到问题的根源。
-
-
-利用bug报告
------------
-
-练习内核开发技能的最好办法就是修改其他人报告的bug。你不光可以帮助内核变
-得更加稳定，还可以学会如何解决实际问题从而提高自己的技能，并且让其他开发
-者感受到你的存在。修改bug是赢得其他开发者赞誉的最好办法，因为并不是很多
-人都喜欢浪费时间去修改别人报告的bug。
-
-要尝试修改已知的bug，请访问http://bugzilla.kernel.org网址。如果你想获得
-最新bug的通知，可以订阅bugme-new邮件列表（只有新的bug报告会被寄到这里）
-或者订阅bugme-janitor邮件列表（所有bugzilla的变动都会被寄到这里）。
-
-	https://lists.linux-foundation.org/mailman/listinfo/bugme-new
-	https://lists.linux-foundation.org/mailman/listinfo/bugme-janitors
-
-
-邮件列表
---------
-
-正如上面的文档所描述，大多数的骨干内核开发者都加入了Linux Kernel邮件列
-表。如何订阅和退订列表的细节可以在这里找到：
-	http://vger.kernel.org/vger-lists.html#linux-kernel
-网上很多地方都有这个邮件列表的存档(archive)。可以使用搜索引擎来找到这些
-存档。比如：
-	http://dir.gmane.org/gmane.linux.kernel
-在发信之前，我们强烈建议你先在存档中搜索你想要讨论的问题。很多已经被详细
-讨论过的问题只在邮件列表的存档中可以找到。
-
-大多数内核子系统也有自己独立的邮件列表来协调各自的开发工作。从
-MAINTAINERS文件中可以找到不同话题对应的邮件列表。
-
-很多邮件列表架设在kernel.org服务器上。这些列表的信息可以在这里找到：
-	http://vger.kernel.org/vger-lists.html
-
-在使用这些邮件列表时，请记住保持良好的行为习惯。下面的链接提供了与这些列
-表（或任何其它邮件列表）交流的一些简单规则，虽然内容有点滥竽充数。
-	http://www.albion.com/netiquette/
-
-当有很多人回复你的邮件时，邮件的抄送列表会变得很长。请不要将任何人从抄送
-列表中删除，除非你有足够的理由这么做。也不要只回复到邮件列表。请习惯于同
-一封邮件接收两次（一封来自发送者一封来自邮件列表），而不要试图通过添加一
-些奇特的邮件头来解决这个问题，人们不会喜欢的。
-
-记住保留你所回复内容的上下文和源头。在你回复邮件的顶部保留“某某某说到……”
-这几行。将你的评论加在被引用的段落之间而不要放在邮件的顶部。
-
-如果你在邮件中附带补丁，请确认它们是可以直接阅读的纯文本（如
-Documentation/process/submitting-patches.rst文档中所述）。内核开发者们不希望遇到附件
-或者被压缩了的补丁。只有这样才能保证他们可以直接评论你的每行代码。请确保
-你使用的邮件发送程序不会修改空格和制表符。一个防范性的测试方法是先将邮件
-发送给自己，然后自己尝试是否可以顺利地打上收到的补丁。如果测试不成功，请
-调整或者更换你的邮件发送程序直到它正确工作为止。
-
-总而言之，请尊重其他的邮件列表订阅者。
-
-
-同内核社区合作
-----------------
-
-内核社区的目标就是提供尽善尽美的内核。所以当你提交补丁期望被接受进内核的
-时候，它的技术价值以及其他方面都将被评审。那么你可能会得到什么呢？
-  - 批评
-  - 评论
-  - 要求修改
-  - 要求证明修改的必要性
-  - 沉默
-
-要记住，这些是把补丁放进内核的正常情况。你必须学会听取对补丁的批评和评论，
-从技术层面评估它们，然后要么重写你的补丁要么简明扼要地论证修改是不必要
-的。如果你发的邮件没有得到任何回应，请过几天后再试一次，因为有时信件会湮
-没在茫茫信海中。
-
-你不应该做的事情：
-  - 期望自己的补丁不受任何质疑就直接被接受
-  - 翻脸
-  - 忽略别人的评论
-  - 没有按照别人的要求做任何修改就重新提交
-
-在一个努力追寻最好技术方案的社区里，对于一个补丁有多少好处总会有不同的见
-解。你必须要抱着合作的态度，愿意改变自己的观点来适应内核的风格。或者至少
-愿意去证明你的想法是有价值的。记住，犯错误是允许的，只要你愿意朝着正确的
-方案去努力。
-
-如果你的第一个补丁换来的是一堆修改建议，这是很正常的。这并不代表你的补丁
-不会被接受，也不意味着有人和你作对。你只需要改正所有提出的问题然后重新发
-送你的补丁。
-
-内核社区和公司文化的差异
-------------------------
-
-内核社区的工作模式同大多数传统公司开发队伍的工作模式并不相同。下面这些例
-子，可以帮助你避免某些可能发生问题：
-  用这些话介绍你的修改提案会有好处：
-    - 它同时解决了多个问题
-    - 它删除了2000行代码
-    - 这是补丁，它已经解释了我想要说明的
-    - 我在5种不同的体系结构上测试过它……
-    - 这是一系列小补丁用来……
-    - 这个修改提高了普通机器的性能……
-
-  应该避免如下的说法：
-    - 我们在AIX/ptx/Solaris就是这么做的，所以这么做肯定是好的……
-    - 我做这行已经20年了，所以……
-    - 为了我们公司赚钱考虑必须这么做
-    - 这是我们的企业产品线所需要的
-    - 这里是描述我观点的1000页设计文档
-    - 这是一个5000行的补丁用来……
-    - 我重写了现在乱七八糟的代码，这就是……
-    - 我被规定了最后期限，所以这个补丁需要立刻被接受
-
-另外一个内核社区与大部分传统公司的软件开发队伍不同的地方是无法面对面地交
-流。使用电子邮件和IRC聊天工具做为主要沟通工具的一个好处是性别和种族歧视
-将会更少。Linux内核的工作环境更能接受妇女和少数族群，因为每个人在别人眼
-里只是一个邮件地址。国际化也帮助了公平的实现，因为你无法通过姓名来判断人
-的性别。男人有可能叫李丽，女人也有可能叫王刚。大多数在Linux内核上工作过
-并表达过看法的女性对在linux上工作的经历都给出了正面的评价。
-
-对于一些不习惯使用英语的人来说，语言可能是一个引起问题的障碍。在邮件列表
-中要正确地表达想法必需良好地掌握语言，所以建议你在发送邮件之前最好检查一
-下英文写得是否正确。
-
-
-拆分修改
---------
-
-Linux内核社区并不喜欢一下接收大段的代码。修改需要被恰当地介绍、讨论并且
-拆分成独立的小段。这几乎完全和公司中的习惯背道而驰。你的想法应该在开发最
-开始的阶段就让大家知道，这样你就可以及时获得对你正在进行的开发的反馈。这
-样也会让社区觉得你是在和他们协作，而不是仅仅把他们当作倾销新功能的对象。
-无论如何，你不要一次性地向邮件列表发送50封信，你的补丁序列应该永远用不到
-这么多。
-
-将补丁拆开的原因如下：
-
-1) 小的补丁更有可能被接受，因为它们不需要太多的时间和精力去验证其正确性。
-   一个5行的补丁，可能在维护者看了一眼以后就会被接受。而500行的补丁则
-   需要数个小时来审查其正确性（所需时间随补丁大小增加大约呈指数级增长）。
-
-   当出了问题的时候，小的补丁也会让调试变得非常容易。一个一个补丁地回溯
-   将会比仔细剖析一个被打上的大补丁（这个补丁破坏了其他东西）容易得多。
-
-2）不光发送小的补丁很重要，在提交之前重新编排、化简（或者仅仅重新排列）
-   补丁也是很重要的。
-
-这里有内核开发者Al Viro打的一个比方：
-	“想象一个老师正在给学生批改数学作业。老师并不希望看到学生为了得
-	到正确解法所进行的尝试和产生的错误。他希望看到的是最干净最优雅的
-	解答。好学生了解这点，绝不会把最终解决之前的中间方案提交上去。”
-
-	内核开发也是这样。维护者和评审者不希望看到一个人在解决问题时的思
-	考过程。他们只希望看到简单和优雅的解决方案。
-
-直接给出一流的解决方案，和社区一起协作讨论尚未完成的工作，这两者之间似乎
-很难找到一个平衡点。所以最好尽早开始收集有利于你进行改进的反馈；同时也要
-保证修改分成很多小块，这样在整个项目都准备好被包含进内核之前，其中的一部
-分可能会先被接收。
-
-必须了解这样做是不可接受的：试图将未完成的工作提交进内核，然后再找时间修
-复。
-
-
-证明修改的必要性
-----------------
-除了将补丁拆成小块，很重要的一点是让Linux社区了解他们为什么需要这样修改。
-你必须证明新功能是有人需要的并且是有用的。
-
-
-记录修改
---------
-
-当你发送补丁的时候，需要特别留意邮件正文的内容。因为这里的信息将会做为补
-丁的修改记录(ChangeLog)，会被一直保留以备大家查阅。它需要完全地描述补丁，
-包括：
-  - 为什么需要这个修改
-  - 补丁的总体设计
-  - 实现细节
-  - 测试结果
-
-想了解它具体应该看起来像什么，请查阅以下文档中的“ChangeLog”章节：
-  “The Perfect Patch”
-  	 http://www.ozlabs.org/~akpm/stuff/tpp.txt
-
-
-这些事情有时候做起来很难。要在任何方面都做到完美可能需要好几年时间。这是
-一个持续提高的过程，它需要大量的耐心和决心。只要不放弃，你一定可以做到。
-很多人已经做到了，而他们都曾经和现在的你站在同样的起点上。

-以下为正文
----------------------------------------------------------------------
-这个文件是有关当前使用的魔术值注册表。当你给一个结构添加了一个魔术值，你也应该把这个魔术值添加到这个文件，因为我们最好把用于各种结构的魔术值统一起来。
-
-使用魔术值来保护内核数据结构是一个非常好的主意。这就允许你在运行期检查(a)一个结构是否已经被攻击，或者(b)你已经给一个例行程序通过了一个错误的结构。后一种情况特别地有用---特别是当你通过一个空指针指向结构体的时候。tty源码，例如，经常通过特定驱动使用这种方法并且反复地排列特定方面的结构。
-
-使用魔术值的方法是在结构的开始处声明的，如下：
-
-struct tty_ldisc {
-	int	magic;
-	...
-};
-
-当你以后给内核添加增强功能的时候，请遵守这条规则！这样就会节省数不清的调试时间，特别是一些古怪的情况，例如，数组超出范围并且重新写了超出部分。遵守这个规则，‪这些情况可以被快速地，安全地避免。

+
+这个文件是关于什么的
+--------------------
+
+Linux内核有超过800万行代码，每个版本的贡献者超过1000人，是现存最大、最活跃
+的免费软件项目之一。从1991年开始，这个内核已经发展成为一个最好的操作系统
+组件，运行在袖珍数字音乐播放器、台式PC、现存最大的超级计算机以及所有类型的
+系统上。它是一种适用于几乎任何情况的健壮、高效和可扩展的解决方案。
+
+随着Linux的发展，希望参与其开发的开发人员（和公司）的数量也在增加。硬件供应商
+希望确保Linux能够很好地支持他们的产品，使这些产品对Linux用户具有吸引力。嵌入
+式系统供应商使用Linux作为集成产品的组件，希望Linux能够尽可能地胜任手头的任务。
+分销商和其他基于Linux的软件供应商对Linux内核的功能、性能和可靠性有着明确的
+兴趣。最终用户也常常希望修改Linux，使之更好地满足他们的需求。
+
+Linux最引人注目的特性之一是这些开发人员可以访问它；任何具备必要技能的人都可以
+改进Linux并影响其开发方向。专有产品不能提供这种开放性，这是自由软件的一个特点。
+但是，如果有什么不同的话，内核比大多数其他自由软件项目更开放。一个典型的三个月
+内核开发周期可以涉及1000多个开发人员，他们为100多个不同的公司
+（或者根本没有公司）工作。
+
+与内核开发社区合作并不是特别困难。但是，尽管如此，许多潜在的贡献者在尝试做
+内核工作时遇到了困难。内核社区已经发展了自己独特的操作方式，使其能够在每天
+都要更改数千行代码的环境中顺利运行（并生成高质量的产品）。因此，Linux内核开发
+过程与专有的开发方法有很大的不同也就不足为奇了。
+
+对于新开发人员来说，内核的开发过程可能会让人感到奇怪和恐惧，但这个背后有充分的
+理由和坚实的经验。一个不了解内核社区的方式的开发人员（或者更糟的是，他们试图
+抛弃或规避内核社区的方式）会有一个令人沮丧的体验。开发社区, 在帮助那些试图学习
+的人的同时，没有时间帮助那些不愿意倾听或不关心开发过程的人。
+
+希望阅读本文的人能够避免这种令人沮丧的经历。这里有很多材料，但阅读时所做的
+努力会在短时间内得到回报。开发社区总是需要能让内核变更好的开发人员；下面的
+文本应该帮助您或为您工作的人员加入我们的社区。

+
+代码进入主线的重要性
+--------------------
+
+有些公司和开发人员偶尔会想，为什么他们要费心学习如何与内核社区合作，并将代码
+放入主线内核（“主线”是由Linus Torvalds维护的内核，Linux发行商将其用作基础）。
+在短期内，贡献代码看起来像是一种可以避免的开销；仅仅将代码分开并直接支持用户
+似乎更容易。事实上，保持代码独立（“树外”）是在经济上是错误的。
+
+作为说明树外代码成本的一种方法，下面是内核开发过程的一些相关方面；本文稍后将
+更详细地讨论其中的大部分内容。考虑：
+
+- 所有Linux用户都可以使用合并到主线内核中的代码。它将自动出现在所有启用它的
+  发行版上。不需要驱动程序磁盘、下载，也不需要为多个发行版的多个版本提供支持；
+  对于开发人员和用户来说，这一切都是可行的。并入主线解决了大量的分布和支持问题
+
+- 当内核开发人员努力维护一个稳定的用户空间接口时，内部内核API处于不断变化之中.
+  缺乏一个稳定的内部接口是一个深思熟虑的设计决策；它允许在任何时候进行基本的改
+  进，并产生更高质量的代码。但该策略的一个结果是，如果要使用新的内核，任何树外
+  代码都需要持续的维护。维护树外代码需要大量的工作才能使代码保持工作状态。
+
+  相反，位于主线中的代码不需要这样做，因为一个简单的规则要求进行API更改的任何
+  开发人员也必须修复由于该更改而破坏的任何代码。因此，合并到主线中的代码大大
+  降低了维护成本。
+
+- 除此之外，内核中的代码通常会被其他开发人员改进。令人惊讶的结果可能来自授权
+  您的用户社区和客户改进您的产品。
+
+- 内核代码在合并到主线之前和之后都要经过审查。不管原始开发人员的技能有多强，
+  这个审查过程总是能找到改进代码的方法。审查经常发现严重的错误和安全问题。
+  这对于在封闭环境中开发的代码尤其如此；这种代码从外部开发人员的审查中获益
+  匪浅。树外代码是低质量代码。
+
+- 参与开发过程是您影响内核开发方向的方式。旁观者的抱怨会被听到，但是活跃的
+  开发人员有更强的声音——并且能够实现使内核更好地满足其需求的更改。
+
+- 当单独维护代码时，总是存在第三方为类似功能提供不同实现的可能性。如果发生
+  这种情况，合并代码将变得更加困难——甚至到了不可能的地步。然后，您将面临以下
+  令人不快的选择：（1）无限期地维护树外的非标准特性，或（2）放弃代码并将用户
+  迁移到树内版本。
+
+- 代码的贡献是使整个过程工作的根本。通过贡献代码，您可以向内核添加新功能，并
+  提供其他内核开发人员使用的功能和示例。如果您已经为Linux开发了代码（或者
+  正在考虑这样做），那么您显然对这个平台的持续成功感兴趣；贡献代码是确保成功
+  的最好方法之一。
+
+上述所有理由都适用于任何树外内核代码，包括以专有的、仅二进制形式分发的代码。
+然而，在考虑任何类型的纯二进制内核代码分布之前，还需要考虑其他因素。这些包括：
+
+- 围绕专有内核模块分发的法律问题充其量是模糊的；相当多的内核版权所有者认为，
+  大多数仅限二进制的模块是内核的派生产品，因此，它们的分发违反了GNU通用公共
+  许可证（下面将详细介绍）。您的作者不是律师，本文档中的任何内容都不可能被
+  视为法律建议。封闭源代码模块的真实法律地位只能由法院决定。但不管怎样，困扰
+  这些模块的不确定性仍然存在。
+
+- 二进制模块大大增加了调试内核问题的难度，以至于大多数内核开发人员甚至都不会
+  尝试。因此，只分发二进制模块将使您的用户更难从社区获得支持。
+
+- 对于只支持二进制的模块的发行者来说，支持也更加困难，他们必须为他们希望支持
+  的每个发行版和每个内核版本提供一个版本的模块。为了提供相当全面的覆盖范围，
+  可能需要一个模块的几十个构建，并且每次升级内核时，您的用户都必须单独升级
+  您的模块。
+
+- 上面提到的关于代码评审的所有问题都更加存在于封闭源代码。由于该代码根本不可
+  用，因此社区无法对其进行审查，毫无疑问，它将存在严重问题。
+
+尤其是嵌入式系统的制造商，可能会倾向于忽视本节中所说的大部分内容，因为他们
+相信自己正在商用一种使用冻结内核版本的独立产品，在发布后不需要再进行开发。
+这个论点忽略了广泛的代码审查的价值以及允许用户向产品添加功能的价值。但这些
+产品也有有限的商业寿命，之后必须发布新版本的产品。在这一点上，代码在主线上
+并得到良好维护的供应商将能够更好地占位，以使新产品快速上市。
+
+许可
+----
+
+代码是根据一些许可证提供给Linux内核的，但是所有代码都必须与GNU通用公共许可
+证（GPLV2）的版本2兼容，该版本是覆盖整个内核分发的许可证。在实践中，这意味
+着所有代码贡献都由GPLv2（可选地，语言允许在更高版本的GPL下分发）或3子句BSD
+许可（New BSD License, 译者注）覆盖。任何不包含在兼容许可证中的贡献都不会
+被接受到内核中。
+
+贡献给内核的代码不需要（或请求）版权分配。合并到主线内核中的所有代码都保留
+其原始所有权；因此，内核现在拥有数千个所有者。
+
+这种所有权结构的一个暗示是，任何改变内核许可的尝试都注定会失败。很少有实际
+的场景可以获得所有版权所有者的同意（或者从内核中删除他们的代码）。因此，特
+别是，在可预见的将来，不可能迁移到GPL的版本3。
+
+所有贡献给内核的代码都必须是合法的免费软件。因此，不接受匿名（或匿名）贡献
+者的代码。所有贡献者都需要在他们的代码上“sign off”，声明代码可以在GPL下与内
+核一起分发。无法提供未被其所有者许可为免费软件的代码，或可能为内核造成版权
+相关问题的代码（例如，由缺乏适当保护的反向工程工作派生的代码）不能被接受。
+
+有关版权相关问题的问题在Linux开发邮件列表中很常见。这样的问题通常会得到不少
+答案，但要记住，回答这些问题的人不是律师，不能提供法律咨询。如果您有关于
+Linux源代码的法律问题，那么与了解该领域的律师交流是无法替代的。依靠从技术
+邮件列表中获得的答案是一件冒险的事情。

+
+开发流程如何工作
+================
+
+90年代早期的Linux内核开发是一件相当松散的事情，涉及的用户和开发人员相对较
+少。由于拥有数以百万计的用户群，并且在一年的时间里有大约2000名开发人员参与
+进来，内核因此必须发展许多流程来保持开发的顺利进行。要成为流程的有效组成
+部分，需要对流程的工作方式有一个扎实的理解。
+
+总览
+----
+
+内核开发人员使用一个松散的基于时间的发布过程，每两到三个月发布一次新的主要
+内核版本。最近的发布历史记录如下：
+
+	======  =================
+	4.11	四月 30, 2017
+	4.12	七月 2, 2017
+	4.13	九月 3, 2017
+	4.14	十一月 12, 2017
+	4.15	一月 28, 2018
+	4.16	四月 1, 2018
+	======  =================
+
+每4.x版本都是一个主要的内核版本，具有新特性、内部API更改等等。一个典型的4.x
+版本包含大约13000个变更集，变更了几十万行代码。因此，4.x是Linux内核开发的前
+沿；内核使用滚动开发模型，不断集成重大变化。
+
+对于每个版本的补丁合并，遵循一个相对简单的规则。在每个开发周期的开始，“合并
+窗口”被打开。当时，被认为足够稳定（并且被开发社区接受）的代码被合并到主线内
+核中。在这段时间内，新开发周期的大部分变更（以及所有主要变更）将以接近每天
+1000次变更（“补丁”或“变更集”）的速度合并。
+
+（顺便说一句，值得注意的是，合并窗口期间集成的更改并不是凭空产生的；它们是
+提前收集、测试和分级的。稍后将详细描述该过程的工作方式）。
+
+合并窗口持续大约两周。在这段时间结束时，LinusTorvalds将声明窗口已关闭，并
+释放第一个“rc”内核。例如，对于目标为4.14的内核，在合并窗口结束时发生的释放
+将被称为4.14-rc1。RC1版本是一个信号，表示合并新特性的时间已经过去，稳定下一
+个内核的时间已经开始。
+
+在接下来的6到10周内，只有修复问题的补丁才应该提交给主线。有时会允许更大的
+更改，但这种情况很少发生；试图在合并窗口外合并新功能的开发人员往往会受到不
+友好的接待。一般来说，如果您错过了给定特性的合并窗口，最好的做法是等待下一
+个开发周期。（对于以前不支持的硬件，偶尔会对驱动程序进行例外；如果它们不
+改变已有代码，则不会导致回归，并且应该可以随时安全地添加）。
+
+随着修复程序进入主线，补丁速度将随着时间的推移而变慢。Linus大约每周发布一次
+新的-rc内核；一个正常的系列将在-rc6和-rc9之间，内核被认为足够稳定并最终发布。
+然后，整个过程又重新开始了。
+
+例如，这里是4.16的开发周期进行情况（2018年的所有日期）:
+
+	==============  ==============================
+	一月 28	        4.15 稳定版发布
+	二月 11	        4.16-rc1, 合并窗口关闭
+	二月 18	        4.16-rc2
+	二月 25	        4.16-rc3
+	三月 4		4.16-rc4
+	三月 11	        4.16-rc5
+	三月 18	        4.16-rc6
+	三月 25	        4.16-rc7
+	四月 1		4.16 稳定版发布
+	==============  ==============================
+
+开发人员如何决定何时结束开发周期并创建稳定的版本？使用的最重要的指标是以前
+版本的回归列表。不欢迎出现任何错误，但是那些破坏了以前能工作的系统的错误被
+认为是特别严重的。因此，导致回归的补丁是不受欢迎的，很可能在稳定期内删除。
+
+开发人员的目标是在稳定发布之前修复所有已知的回归。在现实世界中，这种完美是
+很难实现的；在这种规模的项目中，变量太多了。有一点，延迟最终版本只会使问题
+变得更糟；等待下一个合并窗口的一堆更改将变大，从而在下次创建更多的回归错误。
+因此，大多数4.x内核都有一些已知的回归错误，不过，希望没有一个是严重的。
+
+一旦一个稳定的版本发布，它正在进行的维护工作就被移交给“稳定团队”，目前由
+Greg Kroah-Hartman组成。稳定团队将使用4.x.y编号方案不定期的发布稳定版本的更
+新。要加入更新版本，补丁程序必须（1）修复一个重要的bug，（2）已经合并到
+下一个开发主线中。内核通常会在超过其初始版本的一个以上的开发周期内接收稳定
+的更新。例如，4.13内核的历史如下
+
+	==============  ===============================
+        九月 3 	        4.13 稳定版发布
+	九月 13	        4.13.1
+	九月 20	        4.13.2
+	九月 27	        4.13.3
+	十月 5	        4.13.4
+	十月 12         4.13.5
+	...	        ...
+	十一月 24       4.13.16
+	==============  ===============================
+
+4.13.16是4.13版本的最终稳定更新。
+
+有些内核被指定为“长期”内核；它们将得到更长时间的支持。在本文中，当前的长期
+内核及其维护者是：
+
+	======  ======================  ==============================
+	3.16	Ben Hutchings		(长期稳定内核)
+	4.1	Sasha Levin
+	4.4	Greg Kroah-Hartman	(长期稳定内核)
+	4.9	Greg Kroah-Hartman
+	4.14	Greg Kroah-Hartman
+	======  ======================  ==============================
+
+为长期支持选择内核纯粹是维护人员有必要和时间来维护该版本的问题。目前还没有
+为即将发布的任何特定版本提供长期支持的已知计划。
+
+补丁的生命周期
+--------------
+
+补丁不会直接从开发人员的键盘进入主线内核。相反，有一个稍微复杂（如果有些非
+正式）的过程，旨在确保对每个补丁进行质量审查，并确保每个补丁实现了一个在主线
+中需要的更改。对于小的修复，这个过程可能会很快发生，或者，在大的和有争议的
+变更的情况下，会持续数年。许多开发人员的挫折来自于对这个过程缺乏理解或者
+试图绕过它。
+
+为了减少这种挫折感，本文将描述补丁如何进入内核。下面是一个介绍，它以某种
+理想化的方式描述了这个过程。更详细的过程将在后面的章节中介绍。
+
+补丁程序经历的阶段通常是：
+
+- 设计。这就是补丁的真正需求——以及满足这些需求的方式——的所在。设计工作通常
+  是在不涉及社区的情况下完成的，但是如果可能的话，最好是在公开的情况下完成
+  这项工作；这样可以节省很多稍后再重新设计的时间。
+
+- 早期评审。补丁被发布到相关的邮件列表中，列表中的开发人员会回复他们可能有
+  的任何评论。如果一切顺利的话，这个过程应该会发现补丁的任何主要问题。
+
+- 更广泛的评审。当补丁接近准备好纳入主线时，它应该被相关的子系统维护人员
+  接受——尽管这种接受并不能保证补丁会一直延伸到主线。补丁将出现在维护人员的
+  子系统树中，并进入 -next 树（如下所述）。当流程工作时，此步骤将导致对补丁
+  进行更广泛的审查，并发现由于将此补丁与其他人所做的工作集成而导致的任何
+  问题。
+
+- 请注意，大多数维护人员也有日常工作，因此合并补丁可能不是他们的最高优先级。
+  如果您的补丁程序得到了关于所需更改的反馈，那么您应该进行这些更改，或者为
+  不应该进行这些更改的原因辩护。如果您的补丁没有评审意见，但没有被其相应的
+  子系统或驱动程序维护者接受，那么您应该坚持不懈地将补丁更新到当前内核，使
+  其干净地应用，并不断地将其发送以供审查和合并。
+
+- 合并到主线。最终，一个成功的补丁将被合并到由LinusTorvalds管理的主线存储库
+  中。此时可能会出现更多的评论和/或问题；开发人员应对这些问题并解决出现的
+  任何问题很重要。
+
+- 稳定版发布。可能受补丁影响的用户数量现在很大，因此可能再次出现新的问题。
+
+- 长期维护。虽然开发人员在合并代码后可能会忘记代码，但这种行为往往会给开发
+  社区留下不良印象。合并代码消除了一些维护负担，因为其他代码将修复由API
+  更改引起的问题。但是，如果代码要长期保持有用，原始开发人员应该继续为
+  代码负责。
+
+内核开发人员（或他们的雇主）犯的最大错误之一是试图将流程简化为一个
+“合并到主线”步骤。这种方法总是会让所有相关人员感到沮丧。
+
+补丁如何进入内核
+----------------
+
+只有一个人可以将补丁合并到主线内核存储库中：LinusTorvalds。但是，在进入
+2.6.38内核的9500多个补丁中，只有112个（大约1.3%）是由Linus自己直接选择的。
+内核项目已经发展到一个规模，没有一个开发人员可以在没有支持的情况下检查和
+选择每个补丁。内核开发人员处理这种增长的方式是通过使用围绕信任链构建的
+助理系统。
+
+内核代码库在逻辑上被分解为一组子系统：网络、特定的体系结构支持、内存管理、
+视频设备等。大多数子系统都有一个指定的维护人员，开发人员对该子系统中的代码
+负有全部责任。这些子系统维护者（松散地）是他们所管理的内核部分的守护者；
+他们（通常）会接受一个补丁以包含到主线内核中。
+
+子系统维护人员每个人都使用git源代码管理工具管理自己版本的内核源代码树。Git
+等工具（以及Quilt或Mercurial等相关工具）允许维护人员跟踪补丁列表，包括作者
+信息和其他元数据。在任何给定的时间，维护人员都可以确定他或她的存储库中的哪
+些补丁在主线中找不到。
+
+当合并窗口打开时，顶级维护人员将要求Linus从其存储库中“拉出”他们为合并选择
+的补丁。如果Linus同意，补丁流将流向他的存储库，成为主线内核的一部分。
+Linus对拉操作中接收到的特定补丁的关注程度各不相同。很明显，有时他看起来很
+关注。但是，作为一般规则，Linus相信子系统维护人员不会向上游发送坏补丁。
+
+子系统维护人员反过来也可以从其他维护人员那里获取补丁。例如，网络树是由首先
+在专用于网络设备驱动程序、无线网络等的树中积累的补丁构建的。此存储链可以
+任意长，但很少超过两个或三个链接。由于链中的每个维护者都信任那些管理较低
+级别树的维护者，所以这个过程称为“信任链”。
+
+显然，在这样的系统中，获取内核补丁取决于找到正确的维护者。直接向Linus发送
+补丁通常不是正确的方法。
+
+Next 树
+-------
+
+子系统树链引导补丁流到内核，但它也提出了一个有趣的问题：如果有人想查看为
+下一个合并窗口准备的所有补丁怎么办？开发人员将感兴趣的是，还有什么其他的
+更改有待解决，以查看是否存在需要担心的冲突；例如，更改核心内核函数原型的
+修补程序将与使用该函数旧形式的任何其他修补程序冲突。审查人员和测试人员希望
+在所有这些变更到达主线内核之前，能够访问它们的集成形式中的变更。您可以从所有
+有趣的子系统树中提取更改，但这将是一项大型且容易出错的工作。
+
+答案以-next树的形式出现，在这里子系统树被收集以供测试和审查。Andrew Morton
+维护的这些旧树被称为“-mm”（用于内存管理，这就是它的启动名字）。-mm 树集成了
+一长串子系统树中的补丁；它还包含一些旨在帮助调试的补丁。
+
+除此之外，-mm 还包含大量由Andrew直接选择的补丁。这些补丁可能已经发布在邮件
+列表上，或者它们可能应用于内核中没有指定子系统树的部分。结果，-mm 作为一种
+最后手段的子系统树运行；如果没有其他明显的路径可以让补丁进入主线，那么它很
+可能以-mm 结束。累积在-mm 中的各种补丁最终将被转发到适当的子系统树，或者直接
+发送到Linus。在典型的开发周期中，大约5-10%的补丁通过-mm 进入主线。
+
+当前-mm 补丁可在“mmotm”（-mm of the moment）目录中找到，地址：
+
+        http://www.ozlabs.org/~akpm/mmotm/
+
+然而，使用mmotm树可能是一种令人沮丧的体验；它甚至可能无法编译。
+
+下一个周期补丁合并的主要树是linux-next，由Stephen Rothwell 维护。根据设计
+linux-next 是下一个合并窗口关闭后主线的快照。linux-next树在Linux-kernel 和
+Linux-next 邮件列表中发布，可从以下位置下载：
+
+        http://www.kernel.org/pub/linux/kernel/next/
+
+Linux-next 已经成为内核开发过程中不可或缺的一部分；在一个给定的合并窗口中合并
+的所有补丁都应该在合并窗口打开之前的一段时间内找到进入Linux-next 的方法。
+
+Staging 树
+----------
+
+内核源代码树包含drivers/staging/directory，其中有许多驱动程序或文件系统的
+子目录正在被添加到内核树中。它们然需要更多的工作的时候可以保留在
+driver/staging目录中；一旦完成，就可以将它们移到内核中。这是一种跟踪不符合
+Linux内核编码或质量标准的驱动程序的方法，但人们可能希望使用它们并跟踪开发。
+
+Greg Kroah Hartman 目前负责维护staging 树。仍需要工作的驱动程序将发送给他，
+每个驱动程序在drivers/staging/中都有自己的子目录。除了驱动程序源文件之外，
+目录中还应该有一个TODO文件。todo文件列出了驱动程序需要接受的挂起的工作，
+以及驱动程序的任何补丁都应该抄送的人员列表。当前的规则要求，staging的驱动
+程序必须至少正确编译。
+
+Staging 是一种相对容易的方法，可以让新的驱动程序进入主线，幸运的是，他们会
+引起其他开发人员的注意，并迅速改进。然而，进入staging并不是故事的结尾；
+staging中没有看到常规进展的代码最终将被删除。经销商也倾向于相对不愿意使用
+staging驱动程序。因此，在成为一名合适的主线驱动的路上，staging 充其量只是
+一个停留。
+
+工具
+----
+
+从上面的文本可以看出，内核开发过程在很大程度上依赖于在不同方向上聚集补丁的
+能力。如果没有适当强大的工具，整个系统将无法在任何地方正常工作。关于如何使用
+这些工具的教程远远超出了本文档的范围，但是还是有一些指南的空间。
+
+到目前为止，内核社区使用的主要源代码管理系统是git。Git是在自由软件社区中开发
+的许多分布式版本控制系统之一。它非常适合内核开发，因为它在处理大型存储库和
+大量补丁时性能非常好。它还有一个难以学习和使用的名声，尽管随着时间的推移它
+变得更好了。对于内核开发人员来说，对Git的某种熟悉几乎是一种要求；即使他们不
+将它用于自己的工作，他们也需要Git来跟上其他开发人员（以及主线）正在做的事情。
+
+现在几乎所有的Linux发行版都打包了Git。主页位于：
+
+        http://git-scm.com/
+
+那个页面有指向文档和教程的指针。
+
+在不使用git的内核开发人员中，最流行的选择几乎肯定是mercurial：
+
+        http://www.seleric.com/mercurial/
+
+Mercurial与Git共享许多特性，但它提供了一个界面，许多人觉得它更易于使用。
+
+另一个值得了解的工具是quilt:
+
+        http://savannah.nongnu.org/projects/quilt
+
+Quilt 是一个补丁管理系统，而不是源代码管理系统。它不会随着时间的推移跟踪历史；
+相反，它面向根据不断发展的代码库跟踪一组特定的更改。一些主要的子系统维护人员
+使用Quilt来管理打算向上游移动的补丁。对于某些树的管理（例如-mm），quilt 是
+最好的工具。
+
+邮件列表
+--------
+
+大量的Linux内核开发工作是通过邮件列表完成的。如果不在某个地方加入至少一个列表，
+就很难成为社区中一个功能完备的成员。但是，Linux邮件列表对开发人员来说也是一个
+潜在的危险，他们可能会被一堆电子邮件淹没，违反Linux列表上使用的约定，或者
+两者兼而有之。
+
+大多数内核邮件列表都在vger.kernel.org上运行；主列表位于：
+
+        http://vger.kernel.org/vger-lists.html
+
+不过，也有一些列表托管在别处；其中一些列表位于lists.redhat.com。
+
+当然，内核开发的核心邮件列表是linux-kernel。这个名单是一个令人生畏的地方；
+每天的信息量可以达到500条，噪音很高，谈话技术性很强，参与者并不总是表现出
+高度的礼貌。但是，没有其他地方可以让内核开发社区作为一个整体聚集在一起；
+避免使用此列表的开发人员将错过重要信息。
+
+有一些提示可以帮助在linux-kernel生存：
+
+- 将邮件转移到单独的文件夹，而不是主邮箱。我们必须能够持续地忽略洪流。
+
+- 不要试图跟踪每一次谈话-其他人都不会。重要的是要对感兴趣的主题（尽管请
+  注意，长时间的对话可以在不更改电子邮件主题行的情况下偏离原始主题）和参与
+  的人进行筛选。
+
+- 不要挑事。如果有人试图激起愤怒的反应，忽略他们。
+
+- 当响应Linux内核电子邮件（或其他列表上的电子邮件）时，请为所有相关人员保留
+  cc:header。如果没有强有力的理由（如明确的请求），则不应删除收件人。一定要
+  确保你要回复的人在cc:list中。这个惯例也使你不必在回复邮件时明确要求被抄送。
+
+- 在提出问题之前，搜索列表档案（和整个网络）。有些开发人员可能会对那些显然
+  没有完成家庭作业的人感到不耐烦。
+
+- 避免贴顶帖（把你的答案放在你要回复的引文上面的做法）。这会让你的回答更难
+  理解，印象也很差。
+
+- 询问正确的邮件列表。linux-kernel 可能是通用的讨论点，但它不是从所有子系统
+  中寻找开发人员的最佳场所。
+
+最后一点——找到正确的邮件列表——是开发人员出错的常见地方。在Linux内核上提出与
+网络相关的问题的人几乎肯定会收到一个礼貌的建议，转而在netdev列表上提出，
+因为这是大多数网络开发人员经常出现的列表。还有其他列表可用于scsi、
+video4linux、ide、filesystem等子系统。查找邮件列表的最佳位置是与内核源代码
+一起打包的MAINTAINERS文件。
+
+开始内核开发
+------------
+
+关于如何开始内核开发过程的问题很常见——来自个人和公司。同样常见的是错误，这
+使得关系的开始比必须的更困难。
+
+公司通常希望聘请知名的开发人员来启动开发团队。实际上，这是一种有效的技术。
+但它也往往是昂贵的，而且没有增长经验丰富的内核开发人员储备。考虑到时间的
+投入，可以让内部开发人员加快Linux内核的开发速度。花这个时间可以让雇主拥有
+一批了解内核和公司的开发人员，他们也可以帮助培训其他人。从中期来看，这往往
+是更有利可图的方法。
+
+可以理解的是，单个开发人员往往对起步感到茫然。从一个大型项目开始可能会很
+吓人；人们往往想先用一些较小的东西来测试水域。这是一些开发人员开始创建修补
+拼写错误或轻微编码风格问题的补丁的地方。不幸的是，这样的补丁会产生一定程度
+的噪音，这会分散整个开发社区的注意力，因此，越来越多的人看不起它们。希望向
+社区介绍自己的新开发人员将无法通过这些方式获得他们想要的那种接待。
+
+Andrew Morton 为有抱负的内核开发人员提供了这个建议
+
+::
+
+        所有内核初学者的No.1项目肯定是“确保内核在所有的机器上，你可以触摸
+        到的，始终运行良好" 通常这样做的方法是与其他人一起解决问题（这
+        可能需要坚持！）但这很好——这是内核开发的一部分
+
+(http://lwn.net/articles/283982/)
+
+在没有明显问题需要解决的情况下，建议开发人员查看当前的回归和开放式错误列表.
+解决需要修复的问题没有任何缺点；通过解决这些问题，开发人员将获得处理过程的
+经验，同时与开发社区的其他人建立尊重。

+
+早期规划
+========
+
+当考虑一个Linux内核开发项目时，很可能会直接跳进去开始编码。然而，与任何重要
+的项目一样，成功的许多基础最好是在第一行代码编写之前就做好了。在早期计划和
+沟通中花费一些时间可以节省更多的时间。
+
+详述问题
+--------
+
+与任何工程项目一样，成功的内核增强从要解决的问题的清晰描述开始。在某些情况
+下，这个步骤很容易：例如，当某个特定硬件需要驱动程序时。不过，在其他方面，
+将实际问题与建议的解决方案混淆是很有诱惑力的，这可能会导致困难。
+
+举个例子：几年前，使用Linux音频的开发人员寻求一种方法来运行应用程序，而不因
+系统延迟过大而导致退出或其他工件。他们得到的解决方案是一个内核模块，旨在连
+接到Linux安全模块（LSM）框架中；这个模块可以配置为允许特定的应用程序访问
+实时调度程序。这个模块被实现并发送到Linux内核邮件列表，在那里它立即遇到问题。
+
+对于音频开发人员来说，这个安全模块足以解决他们当前的问题。但是，对于更广泛的
+内核社区来说，这被视为对LSM框架的滥用（LSM框架并不打算授予他们原本不具备的
+进程特权），并对系统稳定性造成风险。他们首选的解决方案包括短期的通过rlimit
+机制进行实时调度访问，以及长期的减少延迟的工作。
+
+然而，音频社区看不到他们实施的特定解决方案的过去；他们不愿意接受替代方案。
+由此产生的分歧使这些开发人员对整个内核开发过程感到失望；其中一个开发人员返回
+到音频列表并发布了以下内容：
+
+        有很多非常好的Linux内核开发人员，但他们往往会被一群傲慢的傻瓜所压倒。
+        试图向这些人传达用户需求是浪费时间。他们太“聪明”了，根本听不到少数人
+        的话。
+
+（http://lwn.net/articles/131776/）
+
+实际情况不同；与特定模块相比，内核开发人员更关心系统稳定性、长期维护以及找到
+正确的问题解决方案。这个故事的寓意是把重点放在问题上——而不是具体的解决方案
+上——并在投入创建代码之前与开发社区讨论这个问题。
+
+因此，在考虑一个内核开发项目时，我们应该得到一组简短问题的答案：
+
+ - 究竟需要解决的问题是什么？
+
+ - 受此问题影响的用户是谁？解决方案应该解决哪些用例？
+
+ - 内核现在为何没能解决这个问题？
+
+只有这样，才能开始考虑可能的解决方案。
+
+
+早期讨论
+--------
+
+在计划内核开发项目时，在开始实施之前与社区进行讨论是很有意义的。早期沟通可以
+通过多种方式节省时间和麻烦：
+
+ - 很可能问题是由内核以您不理解的方式解决的。Linux内核很大，具有许多不明显
+   的特性和功能。并不是所有的内核功能都像人们所希望的那样有文档记录，而且很
+   容易遗漏一些东西。你的作者发出了一个完整的驱动程序，复制了一个新作者不
+   知道的现有驱动程序。重新设计现有轮子的代码不仅浪费，而且不会被接受到主线
+   内核中。
+
+ - 建议的解决方案中可能有一些元素不适用于主线合并。在编写代码之前，最好先
+   了解这样的问题。
+
+ - 其他开发人员完全有可能考虑过这个问题；他们可能有更好的解决方案的想法，并且
+   可能愿意帮助创建这个解决方案。
+
+在内核开发社区的多年经验给了我们一个明确的教训：闭门设计和开发的内核代码总是
+有一些问题，这些问题只有在代码发布到社区中时才会被发现。有时这些问题很严重，
+需要数月或数年的努力才能使代码达到内核社区的标准。一些例子包括：
+
+ - 设计并实现了单处理器系统的DeviceScape网络栈。只有使其适合于多处理器系统，
+   才能将其合并到主线中。在代码中改装锁等等是一项困难的任务；因此，这段代码
+   （现在称为mac80211）的合并被推迟了一年多。
+
+ - Reiser4文件系统包含许多功能，核心内核开发人员认为这些功能应该在虚拟文件
+   系统层中实现。它还包括一些特性，这些特性在不将系统暴露于用户引起的死锁的
+   情况下是不容易实现的。这些问题的最新发现——以及对其中一些问题的拒绝——已经
+   导致Reiser4远离了主线内核。
+
+ - Apparmor安全模块以被认为不安全和不可靠的方式使用内部虚拟文件系统数据结构。
+   这种担心（包括其他）使Apparmor多年不在主线上。
+
+在每一种情况下，通过与内核开发人员的早期讨论，可以避免大量的痛苦和额外的工作。
+
+找谁交流
+--------
+
+当开发人员决定公开他们的计划时，下一个问题是：我们从哪里开始？答案是找到正确
+的邮件列表和正确的维护者。对于邮件列表，最好的方法是在维护者(MAINTAINERS)文件
+中查找要发布的相关位置。如果有一个合适的子系统列表，那么发布它通常比在Linux
+内核上发布更可取；您更有可能接触到在相关子系统中具有专业知识的开发人员，并且
+环境可能具支持性。
+
+找到维护人员可能会有点困难。同样，维护者文件是开始的地方。但是，该文件往往不总
+是最新的，并且并非所有子系统都在那里表示。实际上，维护者文件中列出的人员可能
+不是当前实际担任该角色的人员。因此，当对联系谁有疑问时，一个有用的技巧是使用
+git（尤其是“git-log”）查看感兴趣的子系统中当前活动的用户。看看谁在写补丁，
+如果有人的话，谁会在这些补丁上加上用线签名的。这些人将是帮助新开发项目的最佳
+人选。
+
+找到合适的维护者的任务有时是非常具有挑战性的，以至于内核开发人员添加了一个
+脚本来简化过程：
+
+::
+
+	.../scripts/get_maintainer.pl
+
+当给定“-f”选项时，此脚本将返回给定文件或目录的当前维护者。如果在命令行上传递
+了一个补丁，它将列出可能接收补丁副本的维护人员。有许多选项可以调节
+get_maintainer.pl搜索维护者的难易程度；请小心使用更具攻击性的选项，因为最终
+可能会包括对您正在修改的代码没有真正兴趣的开发人员。
+
+如果所有其他方法都失败了，那么与Andrew Morton交谈可以成为一种有效的方法来跟踪
+特定代码段的维护人员。
+
+何时邮寄？
+----------
+
+如果可能的话，在早期阶段发布你的计划只会有帮助。描述正在解决的问题以及已经
+制定的关于如何实施的任何计划。您可以提供的任何信息都可以帮助开发社区为项目
+提供有用的输入。
+
+在这个阶段可能发生的一件令人沮丧的事情不是敌对的反应，而是很少或根本没有
+反应。可悲的事实是：（1）内核开发人员往往很忙；（2）不缺少有宏伟计划和很少
+代码（甚至代码前景）支持他们的人；（3）没有人有义务审查或评论别人发表的
+想法。除此之外，高级设计常常隐藏一些问题，这些问题只有在有人真正尝试实现
+这些设计时才会被发现；因此，内核开发人员宁愿看到代码。
+
+如果发表评论的请求在评论的方式上没有什么效果，不要假设这意味着对项目没有
+兴趣。不幸的是，你也不能假设你的想法没有问题。在这种情况下，最好的做法是
+继续进行，把你的进展随时通知社区。
+
+获得官方认可
+-----------------------
+
+如果您的工作是在公司环境中完成的，就像大多数Linux内核工作一样，显然，在您将
+公司的计划或代码发布到公共邮件列表之前，必须获得适当授权的经理的许可。发布
+不确定是否兼容GPL的代码可能是有特别问题的；公司的管理层和法律人员越早能够就
+发布内核开发项目达成一致，对参与的每个人都越好。
+
+一些读者可能会认为他们的核心工作是为了支持还没有正式承认存在的产品。将雇主
+的计划公布在公共邮件列表上可能不是一个可行的选择。在这种情况下，有必要考虑
+保密是否真的是必要的；通常不需要把开发计划关在门内。
+
+也就是说，有些情况下，一家公司在开发过程的早期就不能合法地披露其计划。拥有
+经验丰富的内核开发人员的公司可以选择以开环的方式进行，前提是他们以后能够避免
+严重的集成问题。对于没有这种内部专业知识的公司，最好的选择往往是聘请外部
+开发商根据保密协议审查计划。Linux基金会运行了一个NDA程序，旨在帮助解决这种
+情况；
+
+    http://www.linuxfoundation.org/en/NDA_program
+
+这种审查通常足以避免以后出现严重问题，而无需公开披露项目。

+
+使代码正确
+======================
+
+虽然对于一个坚实的、面向社区的设计过程有很多话要说，但是任何内核开发项目的
+证明都在生成的代码中。它是将由其他开发人员检查并合并（或不合并）到主线树中
+的代码。所以这段代码的质量决定了项目的最终成功。
+
+本节将检查编码过程。我们将从内核开发人员出错的几种方式开始。然后重点将转移
+到正确的事情和可以帮助这个任务的工具上。
+
+陷阱
+----
+
+编码风格
+********
+
+内核长期以来都有一种标准的编码风格，如
+:ref:`Documentation/translations/zh_CN/process/coding-style.rst <cn_codingstyle>`
+中所述。在大部分时间里，该文件中描述的政策被认为至多是建议性的。因此，内核
+中存在大量不符合编码风格准则的代码。代码的存在会给内核开发人员带来两个独立
+的危害。
+
+首先，要相信内核编码标准并不重要，也不强制执行。事实上，如果没有按照标准对代
+码进行编码，那么向内核添加新代码是非常困难的；许多开发人员甚至会在审查代码之
+前要求对代码进行重新格式化。一个与内核一样大的代码库需要一些统一的代码，以使
+开发人员能够快速理解其中的任何部分。所以已经没有空间来存放奇怪的格式化代码了。
+
+偶尔，内核的编码风格会与雇主的强制风格发生冲突。在这种情况下，内核的风格必须
+在代码合并之前获胜。将代码放入内核意味着以多种方式放弃一定程度的控制权——包括
+控制代码的格式化方式。
+
+另一个陷阱是假定已经在内核中的代码迫切需要编码样式的修复。开发人员可能会开始
+生成重新格式化补丁，作为熟悉过程的一种方式，或者作为将其名称写入内核变更日志
+的一种方式，或者两者兼而有之。但是纯编码风格的修复被开发社区视为噪音；它们往
+往受到冷遇。因此，最好避免使用这种类型的补丁。由于其他原因，在处理一段代码的
+同时修复它的样式是很自然的，但是编码样式的更改不应该仅为了更改而进行。
+
+编码风格的文档也不应该被视为绝对的法律，这是永远不会被违反的。如果有一个很好
+的理由反对这种样式（例如，如果拆分为适合80列限制的行，那么它的可读性就会大大
+降低），那么就这样做。
+
+请注意，您还可以使用 ``clang-format`` 工具来帮助您处理这些规则，自动重新格式
+化部分代码，并查看完整的文件，以发现编码样式错误、拼写错误和可能的改进。它还
+可以方便地进行排序，包括对齐变量/宏、回流文本和其他类似任务。有关详细信息，请
+参阅文件 :ref:`Documentation/process/clang-format.rst <clangformat>`
+
+抽象层
+******
+
+计算机科学教授教学生以灵活性和信息隐藏的名义广泛使用抽象层。当然，内核广泛
+地使用了抽象；任何涉及数百万行代码的项目都不能做到这一点并存活下来。但经验
+表明，过度或过早的抽象可能和过早的优化一样有害。抽象应用于所需的级别，
+不要过度。
+
+在一个简单的级别上，考虑一个函数的参数，该参数总是由所有调用方作为零传递。
+我们可以保留这个论点: 以防有人最终需要使用它提供的额外灵活性。不过，到那时，
+实现这个额外参数的代码很有可能以某种从未被注意到的微妙方式被破坏——因为它从
+未被使用过。或者，当需要额外的灵活性时，它不会以符合程序员早期期望的方式来
+这样做。内核开发人员通常会提交补丁来删除未使用的参数；一般来说，首先不应该
+添加这些参数。
+
+隐藏硬件访问的抽象层——通常允许大量的驱动程序在多个操作系统中使用——尤其不受
+欢迎。这样的层使代码变得模糊，可能会造成性能损失；它们不属于Linux内核。
+
+另一方面，如果您发现自己从另一个内核子系统复制了大量的代码，那么现在是时候
+问一下，事实上，将这些代码中的一些提取到单独的库中，或者在更高的层次上实现
+这些功能是否有意义。在整个内核中复制相同的代码没有价值。
+
+#ifdef 和预处理
+***************
+
+C预处理器似乎给一些C程序员带来了强大的诱惑，他们认为它是一种有效地将大量灵
+活性编码到源文件中的方法。但是预处理器不是C，大量使用它会导致代码对其他人来
+说更难读取，对编译器来说更难检查正确性。大量的预处理器几乎总是代码需要一些
+清理工作的标志。
+
+使用ifdef的条件编译实际上是一个强大的功能，它在内核中使用。但是很少有人希望
+看到代码被大量地撒上ifdef块。作为一般规则，ifdef的使用应尽可能限制在头文件
+中。有条件编译的代码可以限制函数，如果代码不存在，这些函数就会变成空的。然后
+编译器将悄悄地优化对空函数的调用。结果是代码更加清晰，更容易理解。
+
+C预处理器宏存在许多危险，包括可能对具有副作用且没有类型安全性的表达式进行多
+重评估。如果您试图定义宏，请考虑创建一个内联函数。结果相同的代码，但是内联
+函数更容易读取，不会多次计算其参数，并且允许编译器对参数和返回值执行类型检查。
+
+内联函数
+********
+
+不过，内联函数本身也存在风险。程序员可以倾心于避免函数调用和用内联函数填充源
+文件所固有的效率。然而，这些功能实际上会降低性能。因为它们的代码在每个调用站
+点都被复制，所以它们最终会增加编译内核的大小。反过来，这会对处理器的内存缓存
+造成压力，从而大大降低执行速度。通常，内联函数应该非常小，而且相对较少。毕竟，
+函数调用的成本并不高；大量内联函数的创建是过早优化的典型例子。
+
+一般来说，内核程序员会忽略缓存效果，这会带来危险。在开始的数据结构课程中，经
+典的时间/空间权衡通常不适用于当代硬件。空间就是时间，因为一个大的程序比一个
+更紧凑的程序运行得慢。
+
+最近的编译器在决定一个给定函数是否应该被内联方面扮演着越来越积极的角色。
+因此，“inline”关键字的自由放置可能不仅仅是过度的，它也可能是无关的。
+
+锁
+**
+
+2006年5月，“deviceescape”网络堆栈在GPL下发布，并被纳入主线内核。这是一个受
+欢迎的消息；对Linux中无线网络的支持充其量被认为是不合格的，而deviceescape
+堆栈提供了修复这种情况的承诺。然而，直到2007年6月（2.6.22），这段代码才真
+正进入主线。发生了什么？
+
+这段代码显示了许多闭门造车的迹象。但一个特别大的问题是，它并不是设计用于多
+处理器系统。在合并这个网络堆栈（现在称为mac80211）之前，需要对其进行一个锁
+方案的改造。
+
+曾经，Linux内核代码可以在不考虑多处理器系统所带来的并发性问题的情况下进行
+开发。然而，现在，这个文件是写在双核笔记本电脑上的。即使在单处理器系统上，
+为提高响应能力所做的工作也会提高内核内的并发性水平。编写内核代码而不考虑锁
+的日子已经过去很长了。
+
+可以由多个线程并发访问的任何资源（数据结构、硬件寄存器等）必须由锁保护。新
+的代码应该记住这一要求；事后改装锁是一项相当困难的任务。内核开发人员应该花
+时间充分了解可用的锁原语，以便为作业选择正确的工具。显示对并发性缺乏关注的
+代码进入主线将很困难。
+
+回归
+****
+
+最后一个值得一提的危险是：它可能会引起改变（这可能会带来很大的改进），从而
+导致现有用户的某些东西中断。这种变化被称为“回归”，回归已经成为主线内核最不
+受欢迎的。除少数例外情况外，如果回归不能及时修正，会导致回归的变化将被取消。
+最好首先避免回归。
+
+人们常常争论，如果回归让更多人可以工作，远超过产生问题，那么回归是合理的。
+如果它破坏的一个系统却为十个系统带来新的功能，为什么不进行更改呢？2007年7月，
+Linus对这个问题给出了最佳答案:
+
+::
+        所以我们不会通过引入新问题来修复错误。那样的谎言很疯狂，没有人知道
+        你是否真的有进展。是前进两步，后退一步，还是向前一步，向后两步？
+
+（http://lwn.net/articles/243460/）
+
+一种特别不受欢迎的回归类型是用户空间ABI的任何变化。一旦接口被导出到用户空间，
+就必须无限期地支持它。这一事实使得用户空间接口的创建特别具有挑战性：因为它们
+不能以不兼容的方式进行更改，所以必须第一次正确地进行更改。因此，用户空间界面
+总是需要大量的思考、清晰的文档和广泛的审查。
+
+
+代码检查工具
+------------
+
+至少目前，编写无错误代码仍然是我们中很少人能达到的理想状态。不过，我们希望做
+的是，在代码进入主线内核之前，尽可能多地捕获并修复这些错误。为此，内核开发人
+员已经组装了一系列令人印象深刻的工具，可以自动捕获各种各样的模糊问题。计算机
+发现的任何问题都是一个以后不会困扰用户的问题，因此，只要有可能，就应该使用
+自动化工具。
+
+第一步只是注意编译器产生的警告。当代版本的GCC可以检测（并警告）大量潜在错误。
+通常，这些警告都指向真正的问题。提交以供审阅的代码通常不会产生任何编译器警告。
+在消除警告时，注意了解真正的原因，并尽量避免“修复”，使警告消失而不解决其原因。
+
+请注意，并非所有编译器警告都默认启用。使用“make EXTRA_CFLAGS=-W”构建内核以
+获得完整集合。
+
+内核提供了几个配置选项，可以打开调试功能；大多数配置选项位于“kernel hacking”
+子菜单中。对于任何用于开发或测试目的的内核，都应该启用其中几个选项。特别是，
+您应该打开：
+
+ - 启用 ENABLE_MUST_CHECK and FRAME_WARN 以获得一组额外的警告，以解决使用不
+   推荐使用的接口或忽略函数的重要返回值等问题。这些警告生成的输出可能是冗长
+   的，但您不必担心来自内核其他部分的警告。
+
+ - DEBUG_OBJECTS 将添加代码，以跟踪内核创建的各种对象的生存期，并在出现问题时
+   发出警告。如果要添加创建（和导出）自己的复杂对象的子系统，请考虑添加对对象
+   调试基础结构的支持。
+
+ - DEBUG_SLAB 可以发现各种内存分配和使用错误；它应该用于大多数开发内核。
+
+ - DEBUG_SPINLOCK, DEBUG_ATOMIC_SLEEP and DEBUG_MUTEXES 会发现许多常见的
+   锁定错误.
+
+还有很多其他调试选项，其中一些将在下面讨论。其中一些具有显著的性能影响，不应
+一直使用。但是，在学习可用选项上花费的一些时间可能会在短期内得到多次回报。
+
+其中一个较重的调试工具是锁定检查器或“lockdep”。该工具将跟踪系统中每个锁
+（spinlock或mutex）的获取和释放、获取锁的相对顺序、当前中断环境等等。然后，
+它可以确保总是以相同的顺序获取锁，相同的中断假设适用于所有情况，等等。换句话
+说，lockdep可以找到许多场景，在这些场景中，系统很少会死锁。在部署的系统中，
+这种问题可能会很痛苦（对于开发人员和用户而言）；LockDep允许提前以自动方式
+发现问题。具有任何类型的非普通锁定的代码在提交包含前应在启用lockdep的情况
+下运行。
+
+作为一个勤奋的内核程序员，毫无疑问，您将检查任何可能失败的操作（如内存分配）
+的返回状态。然而，事实上，最终的故障恢复路径可能完全没有经过测试。未测试的
+代码往往会被破坏；如果所有这些错误处理路径都被执行了几次，那么您可能对代码
+更有信心。
+
+内核提供了一个可以做到这一点的错误注入框架，特别是在涉及内存分配的情况下。
+启用故障注入后，内存分配的可配置百分比将失败；这些失败可以限制在特定的代码
+范围内。在启用了故障注入的情况下运行，程序员可以看到当情况恶化时代码如何响
+应。有关如何使用此工具的详细信息，请参阅
+Documentation/fault-injection/fault-injection.txt。
+
+使用“sparse”静态分析工具可以发现其他类型的错误。对于sparse，可以警告程序员
+用户空间和内核空间地址之间的混淆、big endian和small endian数量的混合、在需
+要一组位标志的地方传递整数值等等。sparse必须单独安装(如果您的分发服务器没
+有将其打包，可以在 https://sparse.wiki.kernel.org/index.php/Main_page)找到,
+然后可以通过在make命令中添加“C=1”在代码上运行它。
+
+“Coccinelle”工具 :ref:`http://coccinelle.lip6.fr/ <devtools_coccinelle>`
+能够发现各种潜在的编码问题；它还可以为这些问题提出修复方案。在
+scripts/coccinelle目录下已经打包了相当多的内核“语义补丁”；运行
+“make coccicheck”将运行这些语义补丁并报告发现的任何问题。有关详细信息，请参阅
+:ref:`Documentation/dev-tools/coccinelle.rst <devtools_coccinelle>`
+
+
+其他类型的可移植性错误最好通过为其他体系结构编译代码来发现。如果没有S/390系统
+或Blackfin开发板，您仍然可以执行编译步骤。可以在以下位置找到一组用于x86系统的
+大型交叉编译器：
+
+        http://www.kernel.org/pub/tools/crosstool/
+
+花一些时间安装和使用这些编译器将有助于避免以后的尴尬。
+
+文档
+----
+
+文档通常比内核开发规则更为例外。即便如此，足够的文档将有助于简化将新代码合并
+到内核中的过程，使其他开发人员的生活更轻松，并对您的用户有所帮助。在许多情况
+下，文件的添加已基本上成为强制性的。
+
+任何补丁的第一个文档是其关联的变更日志。日志条目应该描述正在解决的问题、解决
+方案的形式、处理补丁的人员、对性能的任何相关影响，以及理解补丁可能需要的任何
+其他内容。确保changelog说明了为什么补丁值得应用；大量开发人员未能提供这些信息。
+
+任何添加新用户空间界面的代码（包括新的sysfs或/proc文件）都应该包含该界面的
+文档，该文档使用户空间开发人员能够知道他们在使用什么。请参阅
+Documentation/abi/readme，了解如何格式化此文档以及需要提供哪些信息。
+
+文件 :ref:`Documentation/admin-guide/kernel-parameters.rst <kernelparameters>`
+描述了内核的所有引导时间参数。任何添加新参数的补丁都应该向该文件添加适当的
+条目。
+
+任何新的配置选项都必须附有帮助文本，帮助文本清楚地解释了这些选项以及用户可能
+希望何时选择它们。
+
+许多子系统的内部API信息通过专门格式化的注释进行记录；这些注释可以通过
+“kernel-doc”脚本以多种方式提取和格式化。如果您在具有kerneldoc注释的子系统中
+工作，则应该维护它们，并根据需要为外部可用的功能添加它们。即使在没有如此记录
+的领域中，为将来添加kerneldoc注释也没有坏处；实际上，这对于刚开始开发内核的人
+来说是一个有用的活动。这些注释的格式以及如何创建kerneldoc模板的一些信息可以在
+:ref:`Documentation/doc-guide/ <doc_guide>` 上找到。
+
+任何阅读大量现有内核代码的人都会注意到，注释的缺失往往是最值得注意的。再一次，
+对新代码的期望比过去更高；合并未注释的代码将更加困难。这就是说，人们几乎不希望
+用语言注释代码。代码本身应该是可读的，注释解释了更微妙的方面。
+
+某些事情应该总是被注释。使用内存屏障时，应附上一行文字，解释为什么需要设置内存
+屏障。数据结构的锁定规则通常需要在某个地方解释。一般来说，主要数据结构需要全面
+的文档。应该指出单独代码位之间不明显的依赖性。任何可能诱使代码看门人进行错误的
+“清理”的事情都需要一个注释来说明为什么要这样做。等等。
+
+
+内部API更改
+-----------
+
+内核提供给用户空间的二进制接口不能被破坏，除非在最严重的情况下。相反，内核的
+内部编程接口是高度流动的，当需要时可以更改。如果你发现自己不得不处理一个内核
+API，或者仅仅因为它不满足你的需求而不使用特定的功能，这可能是API需要改变的一
+个标志。作为内核开发人员，您有权进行此类更改。
+
+当然, 可以进行API更改，但它们必须是合理的。因此，任何进行内部API更改的补丁都
+应该附带一个关于更改内容和必要原因的描述。这种变化也应该分解成一个单独的补丁，
+而不是埋在一个更大的补丁中。
+
+另一个要点是，更改内部API的开发人员通常要负责修复内核树中被更改破坏的任何代码。
+对于一个广泛使用的函数，这个职责可以导致成百上千的变化，其中许多变化可能与其他
+开发人员正在做的工作相冲突。不用说，这可能是一项大工作，所以最好确保理由是
+可靠的。请注意，coccinelle工具可以帮助进行广泛的API更改。
+
+在进行不兼容的API更改时，应尽可能确保编译器捕获未更新的代码。这将帮助您确保找
+到该接口的树内用处。它还将警告开发人员树外代码存在他们需要响应的更改。支持树外
+代码不是内核开发人员需要担心的事情，但是我们也不必使树外开发人员的生活有不必要
+的困难。

+
+发送补丁
+========
+
+迟早，当您的工作准备好提交给社区进行审查，并最终包含到主线内核中时。不出所料，
+内核开发社区已经发展出一套用于发布补丁的约定和过程；遵循这些约定和过程将使
+参与其中的每个人的生活更加轻松。本文件将试图合理详细地涵盖这些期望；更多信息
+也可在以下文件中找到
+:ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`,
+:ref:`Documentation/process/submitting-drivers.rst  <submittingdrivers>`
+和 :ref:`Documentation/translations/zh_CN/process/submit-checklist.rst <cn_submitchecklist>`.
+
+何时邮寄
+--------
+
+在补丁完全“准备好”之前，有一个不断的诱惑来避免发布补丁。对于简单的补丁，
+这不是问题。但是，如果正在完成的工作很复杂，那么在工作完成之前从社区获得
+反馈就可以获得很多好处。因此，您应该考虑发布正在进行的工作，甚至使Git树
+可用，以便感兴趣的开发人员可以随时赶上您的工作。
+
+当发布还没有准备好包含的代码时，最好在发布本身中这样说。还应提及任何有待完成
+的主要工作和任何已知问题。很少有人会看到那些被认为是半生不熟的补丁，但是那些
+人会想到他们可以帮助你把工作推向正确的方向。
+
+创建补丁之前
+------------
+
+在考虑将补丁发送到开发社区之前，有许多事情应该做。这些包括：
+
+ - 尽可能地测试代码。利用内核的调试工具，确保内核使用所有合理的配置选项组合
+   进行构建，使用跨编译器为不同的体系结构进行构建等。
+
+ - 确保您的代码符合内核编码风格指南。
+
+ - 您的更改是否具有性能影响？如果是这样，您应该运行基准测试来显示您的变更的
+   影响（或好处）；结果的摘要应该包含在补丁中。
+
+ - 确保您有权发布代码。如果这项工作是为雇主完成的，雇主对这项工作具有所有权，
+   并且必须同意根据GPL对其进行放行。
+
+一般来说，在发布代码之前进行一些额外的思考，几乎总是能在短时间内得到回报。
+
+补丁准备
+--------
+
+准备发布补丁可能是一个惊人的工作量，但再次尝试节省时间在这里通常是不明智的，
+即使在短期内。
+
+必须针对内核的特定版本准备补丁。作为一般规则，补丁程序应该基于Linus的Git树中
+的当前主线。当以主线为基础时，从一个众所周知的发布点开始——一个稳定的或RC的
+发布——而不是在一个主线分支任意点。
+
+但是，可能需要针对-mm、linux-next或子系统树生成版本，以便于更广泛的测试和审查。
+根据补丁的区域以及其他地方的情况，针对这些其他树建立补丁可能需要大量的工作来
+解决冲突和处理API更改。
+
+只有最简单的更改才应格式化为单个补丁；其他所有更改都应作为一系列逻辑更改进行。
+分割补丁是一门艺术；一些开发人员花了很长时间来弄清楚如何按照社区期望的方式来
+做。然而，有一些经验法则可以大大帮助：
+
+ - 您发布的补丁程序系列几乎肯定不会是工作系统中的一系列更改。相反，您所做的
+   更改需要在最终形式中加以考虑，然后以有意义的方式进行拆分。开发人员对离散的、
+   自包含的更改感兴趣，而不是您获取这些更改的路径。
+
+ - 每个逻辑上独立的变更都应该格式化为单独的补丁。这些更改可以是小的（“向此
+   结构添加字段”）或大的（例如，添加一个重要的新驱动程序），但它们在概念上
+   应该是小的，并且可以接受一行描述。每个补丁都应该做一个特定的更改，可以单独
+   检查并验证它所做的事情。
+
+ - 作为重申上述准则的一种方法：不要在同一补丁中混合不同类型的更改。如果一个
+   补丁修复了一个关键的安全漏洞，重新排列了一些结构，并重新格式化了代码，那么
+   很有可能它会被忽略，而重要的修复将丢失。
+
+ - 每个补丁都应该产生一个内核，它可以正确地构建和运行；如果补丁系列在中间被
+   中断，那么结果应该仍然是一个工作的内核。补丁系列的部分应用是使用
+   “git bisct”工具查找回归的一个常见场景；如果结果是一个损坏的内核，那么对于
+   那些从事追踪问题的高尚工作的开发人员和用户来说，将使他们的生活更加艰难。
+
+ - 不过，不要过分。一位开发人员曾经将一组编辑内容作为500个单独的补丁发布到一个
+   文件中，这并没有使他成为内核邮件列表中最受欢迎的人。一个补丁可以相当大，
+   只要它仍然包含一个单一的逻辑变更。
+
+ - 用一系列补丁添加一个全新的基础设施是很有诱惑力的，但是在系列中的最后一个
+   补丁启用整个补丁之前，该基础设施是不使用的。如果可能的话，应该避免这种
+   诱惑；如果这个系列增加了回归，那么二分法将指出最后一个补丁是导致问题的
+   补丁，即使真正的bug在其他地方。只要有可能，添加新代码的补丁程序应该立即
+   激活该代码。
+
+创建完美补丁系列的工作可能是一个令人沮丧的过程，在完成“真正的工作”之后需要花费
+大量的时间和思考。但是，如果做得好，这是一段很好的时间。
+
+补丁格式和更改日志
+------------------
+
+所以现在你有了一系列完美的补丁可以发布，但是这项工作还没有完成。每个补丁都
+需要被格式化成一条消息，它可以快速而清晰地将其目的传达给世界其他地方。为此，
+每个补丁将由以下部分组成：
+
+ - 命名补丁作者的可选“from”行。只有当你通过电子邮件传递别人的补丁时，这一行
+   才是必要的，但是如果有疑问，添加它不会有任何伤害。
+
+ - 一行描述补丁的作用。对于没有其他上下文的读者来说，此消息应该足够了解补丁
+   的范围；这是将在“短格式”变更日志中显示的行。此消息通常首先用相关的子系统
+   名称格式化，然后是补丁的目的。例如：
+
+    ::
+
+	gpio: fix build on CONFIG_GPIO_SYSFS=n
+
+ - 一个空白行，后面是补丁内容的详细描述。这个描述可以是必需的；它应该说明补丁
+   的作用以及为什么它应该应用于内核。
+
+ - 一个或多个标记行，至少有一个由补丁作者的：signed-off-by 签名。签名将在下面
+   更详细地描述。
+
+上面的项目一起构成补丁的变更日志。写一篇好的变更日志是一门至关重要但常常被
+忽视的艺术；值得花一点时间来讨论这个问题。当你写一个变更日志时，你应该记住
+有很多不同的人会读你的话。其中包括子系统维护人员和审查人员，他们需要决定是否
+应该包括补丁，分销商和其他维护人员试图决定是否应该将补丁反向移植到其他内核，
+bug搜寻人员想知道补丁是否负责他们正在追查的问题，想知道内核如何变化的用户。
+等等。一个好的变更日志以最直接和最简洁的方式向所有这些人传达所需的信息。
+
+为此，总结行应该描述变更的影响和动机，以及在一行约束条件下可能发生的变化。
+然后，详细的描述可以详述这些主题，并提供任何需要的附加信息。如果补丁修复了
+一个bug，请引用引入该bug的commit（如果可能，请在引用commits时同时提供commit id
+和标题）。如果某个问题与特定的日志或编译器输出相关联，请包含该输出以帮助其他
+人搜索同一问题的解决方案。如果更改是为了支持以后补丁中的其他更改，那么就这么
+说。如果更改了内部API，请详细说明这些更改以及其他开发人员应该如何响应。一般
+来说，你越能把自己放在每个阅读你的changelog的人的位置上，changelog（和内核
+作为一个整体）就越好。
+
+不用说，变更日志应该是将变更提交到修订控制系统时使用的文本。接下来是：
+
+ - 补丁本身，采用统一的（“-u”）补丁格式。将“-p”选项用于diff将使函数名与更改
+   相关联，从而使结果补丁更容易被其他人读取。
+
+您应该避免在补丁中包括对不相关文件（例如，由构建过程生成的文件或编辑器
+备份文件）的更改。文档目录中的文件“dontdiff”在这方面有帮助；使用“-X”选项将
+其传递给diff。
+
+上面提到的标签用于描述各种开发人员如何与这个补丁的开发相关联。
+:ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`
+文档中对它们进行了详细描述；下面是一个简短的总结。每一行的格式如下：
+
+::
+
+	tag: Full Name <email address>  optional-other-stuff
+
+常用的标签有：
+
+ - Signed-off-by: 这是一个开发人员的证明，他或她有权提交补丁以包含到内核中。
+   这是开发来源认证协议，其全文可在
+   :ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`
+   中找到，如果没有适当的签字，则不能合并到主线中。
+
+ - Co-developed-by: 声明补丁是由多个开发人员共同创建的；当几个人在一个补丁上
+   工作时，它用于将属性赋予共同作者（除了 From: 所赋予的作者之外）。因为
+   Co-developed-by: 表示作者身份，所以每个共同开发人, 必须紧跟在相关合作作者
+   的签名之后。具体内容和示例可以在以下文件中找到
+   :ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`
+
+ - Acked-by: 表示另一个开发人员（通常是相关代码的维护人员）同意补丁适合包含
+   在内核中。
+
+ - Tested-by: 声明指定的人已经测试了补丁并发现它可以工作。
+
+ - Reviewed-by: 指定的开发人员已经审查了补丁的正确性；有关详细信息，请参阅
+   :ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`
+
+ - Reported-by: 指定报告此补丁修复的问题的用户；此标记用于提供感谢。
+
+ - Cc：指定的人收到了补丁的副本，并有机会对此发表评论。
+
+在补丁中添加标签时要小心：只有cc:才适合在没有指定人员明确许可的情况下添加。
+
+发送补丁
+--------
+
+在邮寄补丁之前，您还需要注意以下几点：
+
+ - 您确定您的邮件发送程序不会损坏补丁吗？有免费的空白更改或由邮件客户端
+   执行的行包装的补丁不会在另一端复原，并且通常不会进行任何详细检查。如果有
+   任何疑问，把补丁寄给你自己，让你自己相信它是完好无损的。
+
+   :ref:`Documentation/translations/zh_CN/process/email-clients.rst <cn_email_clients>`
+   提供了一些有用的提示，可以让特定的邮件客户机工作以发送补丁。
+
+ - 你确定你的补丁没有愚蠢的错误吗？您应该始终通过scripts/checkpatch.pl运行
+   补丁程序，并解决它提出的投诉。请记住，checkpatch.pl虽然是大量思考内核
+   补丁应该是什么样子的体现，但它并不比您聪明。如果修复checkpatch.pl投诉会
+   使代码变得更糟，请不要这样做。
+
+补丁应始终以纯文本形式发送。请不要将它们作为附件发送；这使得审阅者在答复中更难
+引用补丁的部分。相反，只需将补丁直接放到您的消息中。
+
+邮寄补丁时，重要的是将副本发送给任何可能感兴趣的人。与其他一些项目不同，内核
+鼓励人们错误地发送过多的副本；不要假定相关人员会看到您在邮件列表中的发布。
+尤其是，副本应发送至：
+
+ - 受影响子系统的维护人员。如前所述，维护人员文件是查找这些人员的第一个地方。
+
+ - 其他在同一领域工作的开发人员，尤其是那些现在可能在那里工作的开发人员。使用
+   git查看还有谁修改了您正在处理的文件，这很有帮助。
+
+ - 如果您对错误报告或功能请求做出响应，也可以抄送原始发送人。
+
+ - 将副本发送到相关邮件列表，或者，如果没有其他应用，则发送到Linux内核列表。
+
+ - 如果您正在修复一个bug，请考虑该修复是否应进入下一个稳定更新。如果是这样，
+   stable@vger.kernel.org 应该得到补丁的副本。另外，在补丁本身的标签中添加
+   一个“cc:stable@vger.kernel.org”；这将使稳定团队在修复进入主线时收到通知。
+
+当为一个补丁选择接收者时，最好知道你认为谁最终会接受这个补丁并将其合并。虽然
+可以将补丁直接发送给LinusTorvalds并让他合并，但通常情况下不会这样做。Linus
+很忙，并且有子系统维护人员负责监视内核的特定部分。通常您会希望维护人员合并您
+的补丁。如果没有明显的维护人员，Andrew Morton通常是最后的补丁目标。
+
+补丁需要好的主题行。补丁程序行的规范格式如下：
+
+::
+
+	[PATCH nn/mm] subsys: one-line description of the patch
+
+其中“nn”是补丁的序号，“mm”是系列中补丁的总数，“subsys”是受影响子系统的名称。
+显然，一个单独的补丁可以省略nn/mm。
+
+如果您有一系列重要的补丁，那么通常将介绍性描述作为零部分发送。不过，这种约定
+并没有得到普遍遵循；如果您使用它，请记住简介中的信息不会使它进入内核变更日志。
+因此，请确保补丁本身具有完整的变更日志信息。
+
+一般来说，多部分补丁的第二部分和后续部分应作为对第一部分的回复发送，以便它们
+在接收端都连接在一起。像git和coilt这样的工具有命令，可以通过适当的线程发送
+一组补丁。但是，如果您有一个长系列，并且正在使用git，请远离–chain reply-to
+选项，以避免创建异常深的嵌套。

+
+跟进
+====
+
+在这一点上，您已经遵循了到目前为止给出的指导方针，并且，随着您自己的工程技能
+的增加，已经发布了一系列完美的补丁。即使是经验丰富的内核开发人员也能犯的最大
+错误之一是，认为他们的工作现在已经完成了。事实上，发布补丁意味着进入流程的下
+一个阶段，可能还需要做很多工作。
+
+一个补丁在第一次发布时就非常出色，没有改进的余地,这是很罕见的。内核开发流程
+认识到这一事实，因此，它非常注重对已发布代码的改进。作为代码的作者，您应该与
+内核社区合作，以确保您的代码符合内核的质量标准。如果不参与这个过程，很可能会
+阻止将补丁包含到主线中。
+
+与审阅者合作
+------------
+
+任何意义上的补丁都会导致其他开发人员在审查代码时发表大量评论。对于许多开发
+人员来说，与审查人员合作可能是内核开发过程中最令人生畏的部分。但是，如果你
+记住一些事情，生活会变得容易得多：
+
+ - 如果你已经很好地解释了你的补丁，评论人员会理解它的价值，以及为什么你会
+   费尽心思去写它。但是这个并不能阻止他们提出一个基本的问题：五年或十年后
+   用这个代码维护一个内核会是什么感觉？你可能被要求做出的许多改变——从编码风格
+   的调整到大量的重写——都来自于对Linux的理解，即从现在起十年后，Linux仍将在
+   开发中。
+
+ - 代码审查是一项艰苦的工作，这是一项相对吃力不讨好的工作；人们记得谁编写了
+   内核代码，但对于那些审查它的人来说，几乎没有什么持久的名声。因此，评论
+   人员可能会变得暴躁，尤其是当他们看到同样的错误被一遍又一遍地犯下时。如果
+   你得到了一个看起来愤怒、侮辱或完全冒犯你的评论，抵制以同样方式回应的冲动。
+   代码审查是关于代码的，而不是关于人的，代码审查人员不会亲自攻击您。
+
+ - 同样，代码审查人员也不想以牺牲你雇主的利益为代价来宣传他们雇主的议程。
+   内核开发人员通常希望今后几年能在内核上工作，但他们明白他们的雇主可能会改
+   变。他们真的，几乎毫无例外地，致力于创造他们所能做到的最好的内核；他们并
+   没有试图给雇主的竞争对手造成不适。
+
+所有这些归根结底都是，当审阅者向您发送评论时，您需要注意他们正在进行的技术
+观察。不要让他们的表达方式或你自己的骄傲阻止这种事情的发生。当你在一个补丁
+上得到评论时，花点时间去理解评论人想说什么。如果可能的话，请修复审阅者要求
+您修复的内容。然后回复审稿人：谢谢他们，并描述你将如何回答他们的问题。
+
+请注意，您不必同意审阅者建议的每个更改。如果您认为审阅者误解了您的代码，请
+解释到底发生了什么。如果您对建议的更改有技术上的异议，请描述它并证明您对该
+问题的解决方案是正确的。如果你的解释有道理，审稿人会接受的。不过，如果你的
+解释不能证明是有说服力的，尤其是当其他人开始同意审稿人的观点时，请花些时间
+重新考虑一下。你很容易对自己解决问题的方法视而不见，以至于你没有意识到某个
+问题根本是错误的，或者你甚至没有解决正确的问题。
+
+Andrew Morton建议，每一条不会导致代码更改的评论都应该导致额外的代码注释；
+这可以帮助未来的评论人员避免出现第一次出现的问题。
+
+一个致命的错误是忽视评论，希望它们会消失。他们不会走的。如果您在没有对之前
+收到的注释做出响应的情况下重新发布代码，那么很可能会发现补丁毫无用处。
+
+说到重新发布代码：请记住，审阅者不会记住您上次发布的代码的所有细节。因此，
+提醒审查人员以前提出的问题以及您如何处理这些问题总是一个好主意；补丁变更
+日志是提供此类信息的好地方。审阅者不必搜索列表档案来熟悉上次所说的内容；
+如果您帮助他们开始运行，当他们重新访问您的代码时，他们的心情会更好。
+
+如果你已经试着做正确的事情，但事情仍然没有进展呢？大多数技术上的分歧都可以
+通过讨论来解决，但有时人们只需要做出决定。如果你真的认为这个决定对你不利，
+你可以试着向更高的权力上诉。在这篇文章中，更高的权力倾向于Andrew Morton。
+Andrew在内核开发社区中受i很大的尊重；他经常为似乎被绝望地阻塞事情清障。
+尽管如此，对Andrew的呼吁不应轻而易举，也不应在所有其他替代方案都被探索之前
+使用。当然，记住，他也可能不同意你的意见。
+
+接下来会发生什么
+----------------
+
+如果一个补丁被认为是添加到内核中的一件好事，并且一旦大多数审查问题得到解决，
+下一步通常是进入子系统维护人员的树中。工作方式因子系统而异；每个维护人员都
+有自己的工作方式。特别是，可能有不止一棵树——一棵树，也许，专门用于计划下一
+个合并窗口的补丁，另一棵树用于长期工作。
+
+对于应用于没有明显子系统树（例如内存管理修补程序）的区域的修补程序，默认树
+通常以-mm结尾。影响多个子系统的补丁也可以最终通过-mm树。
+
+包含在子系统树中可以提高补丁的可见性。现在，使用该树的其他开发人员将默认获
+得补丁。子系统树通常也为Linux提供支持，使其内容对整个开发社区可见。在这一点
+上，您很可能会从一组新的审阅者那里得到更多的评论；这些评论需要像上一轮那样
+得到回答。
+
+在这一点上也会发生什么，这取决于你的补丁的性质，是与其他人正在做的工作发生
+冲突。在最坏的情况下，严重的补丁冲突可能会导致一些工作被搁置，以便剩余的补丁
+可以成形并合并。另一些时候，冲突解决将涉及到与其他开发人员合作，可能还会
+在树之间移动一些补丁，以确保所有的应用都是干净的。这项工作可能是一件痛苦的
+事情，但要计算您的福祉：在Linux下一棵树出现之前，这些冲突通常只在合并窗口
+中出现，必须迅速解决。现在可以在合并窗口打开之前，在空闲时解决这些问题。
+
+有朝一日，如果一切顺利，您将登录并看到您的补丁已经合并到主线内核中。祝贺你！
+然而，一旦庆祝活动完成（并且您已经将自己添加到维护人员文件中），就值得记住
+一个重要的小事实：工作仍然没有完成。并入主线带来了自身的挑战。
+
+首先，补丁的可见性再次提高。可能会有新一轮的开发者评论，他们以前不知道这
+个补丁。忽略它们可能很有诱惑力，因为您的代码不再存在任何被合并的问题。但是，
+要抵制这种诱惑，您仍然需要对有问题或建议的开发人员作出响应。
+
+不过，更重要的是：将代码包含在主线中会将代码交给更大的一组测试人员。即使您
+为尚未提供的硬件提供了驱动程序，您也会惊讶于有多少人会将您的代码构建到内核
+中。当然，如果有测试人员，也会有错误报告。
+
+最糟糕的错误报告是回归。如果你的补丁导致回归，你会发现很多不舒服的眼睛盯着
+你；回归需要尽快修复。如果您不愿意或无法修复回归（其他人都不会为您修复），
+那么在稳定期内，您的补丁几乎肯定会被移除。除了否定您为使补丁进入主线所做的
+所有工作之外，如果由于未能修复回归而取消补丁，很可能会使将来的工作更难合并。
+
+在处理完任何回归之后，可能还有其他普通的bug需要处理。稳定期是修复这些错误并
+确保代码在主线内核版本中的首次发布尽可能可靠的最好机会。所以，请回答错误
+报告，并尽可能解决问题。这就是稳定期的目的；一旦解决了旧补丁的任何问题，就
+可以开始创建酷的新补丁。
+
+别忘了，还有其他里程碑也可能会创建bug报告：下一个主线稳定版本，当著名的发行
+商选择包含补丁的内核版本时，等等。继续响应这些报告是您工作的基本骄傲。但是，
+如果这不是足够的动机，那么也值得考虑的是，开发社区会记住那些在合并后对代码
+失去兴趣的开发人员。下一次你发布补丁时，他们会以你以后不会在身边维护它为假
+设来评估它。
+
+其他可能发生的事情
+------------------
+
+有一天，你可以打开你的邮件客户端，看到有人给你寄了一个代码补丁。毕竟，这是
+让您的代码公开存在的好处之一。如果您同意这个补丁，您可以将它转发给子系统
+维护人员（确保包含一个正确的From:行，这样属性是正确的，并添加一个您自己
+的签准），或者回复一个Acked-by，让原始发送者向上发送它。
+
+如果您不同意补丁，请发送一个礼貌的回复，解释原因。如果可能的话，告诉作者需要
+做哪些更改才能让您接受补丁。对于代码的编写者和维护者所反对的合并补丁，存在着
+一定的阻力，但仅此而已。如果你被认为不必要的阻碍了好的工作，那么这些补丁最
+终会经过你身边并进入主线。在Linux内核中，没有人对任何代码拥有绝对的否决权。
+除了Linus。
+
+在非常罕见的情况下，您可能会看到完全不同的东西：另一个开发人员发布了针对您
+的问题的不同解决方案。在这一点上，两个补丁中的一个可能不会合并，“我的在这里
+是第一个”不被认为是一个令人信服的技术论据。如果有人的补丁取代了你的补丁而进
+入了主线，那么只有一种方法可以回应你：高兴你的问题得到解决，继续你的工作。
+以这种方式把一个人的工作推到一边可能会伤害和气馁，但是在他们忘记了谁的补丁
+真正被合并很久之后，社区会记住你的反应。

+
+高级主题
+========
+
+现在，希望您能够掌握开发流程的工作方式。然而，还有更多的东西要学！本节将介绍
+一些主题，这些主题对希望成为Linux内核开发过程常规部分的开发人员有帮助。
+
+使用Git管理补丁
+---------------
+
+内核使用分布式版本控制始于2002年初，当时Linus首次开始使用专有的Bitkeeper应用
+程序。虽然bitkeeper存在争议，但它所体现的软件版本管理方法却肯定不是。分布式
+版本控制可以立即加速内核开发项目。在当前的时代，有几种免费的比特保持器替代品。
+无论好坏，内核项目都将Git作为其选择的工具。
+
+使用Git管理补丁可以使开发人员的生活更加轻松，尤其是随着补丁数量的增加。Git
+也有其粗糙的边缘和一定的危险，它是一个年轻和强大的工具，仍然在其开发人员完善
+中。本文档不会试图教会读者如何使用git；这会是个巨长的文档。相反，这里的重点
+将是Git如何特别适合内核开发过程。想要加快Git的开发人员可以在以下网站上找到
+更多信息：
+
+	http://git-scm.com/
+
+	http://www.kernel.org/pub/software/scm/git/docs/user-manual.html
+
+在尝试使用它使补丁可供其他人使用之前，第一要务是阅读上述站点，对Git的工作
+方式有一个扎实的了解。使用Git的开发人员应该能够获得主线存储库的副本，探索
+修订历史，提交对树的更改，使用分支等。了解Git用于重写历史的工具（如Rebase）
+也很有用。Git有自己的术语和概念；Git的新用户应该了解refs、远程分支、索引、
+快进合并、推拉、分离头等。一开始可能有点吓人，但这些概念不难通过一点学习来
+理解。
+
+使用git生成通过电子邮件提交的补丁是提高速度的一个很好的练习。
+
+当您准备好开始安装Git树供其他人查看时，您当然需要一个可以从中提取的服务器。
+如果您有一个可以访问Internet的系统，那么使用git守护进程设置这样的服务器相
+对简单。否则，免费的公共托管网站（例如github）开始出现在网络上。成熟的开发
+人员可以在kernel.org上获得一个帐户，但这些帐户并不容易找到；有关更多信息，
+请参阅 http://kernel.org/faq/
+
+正常的Git工作流程涉及到许多分支的使用。每一条开发线都可以分为单独的“主题
+分支”，并独立维护。Git的分支机构很便宜，没有理由不免费使用它们。而且，在
+任何情况下，您都不应该在任何您打算让其他人从中受益的分支中进行开发。应该
+小心地创建公开可用的分支；当它们处于完整的形式并准备好运行时(而不是之前），
+合并开发分支的补丁。
+
+Git提供了一些强大的工具，可以让您重写开发历史。一个不方便的补丁（比如说，
+一个打破二分法的补丁，或者有其他一些明显的缺陷）可以在适当的位置修复，或者
+完全从历史中消失。一个补丁系列可以被重写，就好像它是在今天的主线之上写的
+一样，即使你已经花了几个月的时间在写它。可以透明地将更改从一个分支转移到另
+一个分支。等等。明智地使用git修改历史的能力可以帮助创建问题更少的干净补丁集。
+
+然而，过度使用这种能力可能会导致其他问题，而不仅仅是对创建完美项目历史的
+简单痴迷。重写历史将重写该历史中包含的更改，将经过测试（希望）的内核树变
+为未经测试的内核树。但是，除此之外，如果开发人员没有对项目历史的共享视图，
+他们就无法轻松地协作；如果您重写了其他开发人员拉入他们存储库的历史，您将
+使这些开发人员的生活更加困难。因此，这里有一个简单的经验法则：被导出到其他
+人的历史在此后通常被认为是不可变的。
+
+因此，一旦将一组更改推送到公开可用的服务器上，就不应该重写这些更改。如果您
+尝试强制进行不会导致快进合并（即不共享同一历史记录的更改）的更改，Git将尝
+试强制执行此规则。可以重写此检查，有时可能需要重写导出的树。在树之间移动变
+更集以避免Linux-next中的冲突就是一个例子。但这种行为应该是罕见的。这就是为
+什么开发应该在私有分支中进行（必要时可以重写）并且只有在公共分支处于合理的
+高级状态时才转移到公共分支中的原因之一。
+
+当主线（或其他一组变更所基于的树）前进时，很容易与该树合并以保持领先地位。
+对于一个私有的分支，rebasing 可能是一个很容易跟上另一棵树的方法，但是一旦
+一棵树被导出到全世界，rebasing就不是一个选项。一旦发生这种情况，就必须进行
+完全合并（merge）。合并有时是很有意义的，但是过于频繁的合并会不必要地扰乱
+历史。在这种情况下，建议的技术是不经常合并，通常只在特定的发布点（如主线-rc
+发布）合并。如果您对特定的更改感到紧张，则可以始终在私有分支中执行测试合并。
+在这种情况下，git rerere 工具很有用；它记住合并冲突是如何解决的，这样您就
+不必重复相同的工作。
+
+关于Git这样的工具的一个最大的反复抱怨是：补丁从一个存储库到另一个存储库的
+大量移动使得很容易陷入错误建议的变更中，这些变更避开审查雷达进入主线。当内
+核开发人员看到这种情况发生时，他们往往会感到不高兴；在Git树上放置未查看或
+主题外的补丁可能会影响您将来获取树的能力。引用Linus:
+
+::
+
+        你可以给我发补丁，但要我从你哪里取一个Git补丁，我需要知道你知道
+        你在做什么，我需要能够相信事情而不去检查每个个人改变。
+
+（http://lwn.net/articles/224135/）。
+
+为了避免这种情况，请确保给定分支中的所有补丁都与相关主题紧密相关；“驱动程序
+修复”分支不应更改核心内存管理代码。而且，最重要的是，不要使用Git树来绕过
+审查过程。不时的将树的摘要发布到相关的列表中，当时间合适时，请求
+Linux-next 中包含该树。
+
+如果其他人开始发送补丁以包含到您的树中，不要忘记查看它们。还要确保您维护正确
+的作者信息； ``git am`` 工具在这方面做得最好，但是如果它通过第三方转发给您，
+您可能需要在补丁中添加“From：”行。
+
+请求pull操作时，请务必提供所有相关信息：树的位置、要拉的分支以及拉操作将导致
+的更改。在这方面，git request pull 命令非常有用；它将按照其他开发人员的预期
+格式化请求，并检查以确保您记住了将这些更改推送到公共服务器。
+
+审查补丁
+--------
+
+一些读者当然会反对将本节与“高级主题”放在一起，因为即使是刚开始的内核开发人员
+也应该检查补丁。当然，学习如何在内核环境中编程没有比查看其他人发布的代码更好
+的方法了。此外，审阅者永远供不应求；通过查看代码，您可以对整个流程做出重大贡献。
+
+审查代码可能是一个令人生畏的前景，特别是对于一个新的内核开发人员来说，他们
+可能会对公开询问代码感到紧张，而这些代码是由那些有更多经验的人发布的。不过，
+即使是最有经验的开发人员编写的代码也可以得到改进。也许对评审员（所有评审员）
+最好的建议是：把评审评论当成问题而不是批评。询问“在这条路径中如何释放锁？”
+总是比说“这里的锁是错误的”更好。
+
+不同的开发人员将从不同的角度审查代码。一些主要关注的是编码样式以及代码行是
+否有尾随空格。其他人将主要关注补丁作为一个整体实现的变更是否对内核有好处。
+然而，其他人会检查是否存在锁定问题、堆栈使用过度、可能的安全问题、在其他
+地方发现的代码重复、足够的文档、对性能的不利影响、用户空间ABI更改等。所有
+类型的检查，如果它们导致更好的代码进入内核，都是受欢迎和值得的。

+更多信息
+========
+
+关于Linux内核开发和相关主题的信息来源很多。首先是在内核源代码分发中找到的
+文档目录。顶级 :ref:`Documentation/translations/zh_CN/process/howto.rst <cn_process_howto>`
+文件是一个重要的起点
+:ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`
+和 :ref:`process/submitting-drivers.rst <submittingdrivers>`
+也是所有内核开发人员都应该阅读的内容。许多内部内核API都是使用kerneldoc机制
+记录的；“make htmldocs”或“make pdfdocs”可用于以HTML或PDF格式生成这些文档（
+尽管某些发行版提供的tex版本会遇到内部限制，无法正确处理文档）。
+
+不同的网站在各个细节层次上讨论内核开发。您的作者想谦虚地建议用 http://lwn.net/
+作为来源；有关许多特定内核主题的信息可以通过以下网址的lwn内核索引找到：
+
+        http://lwn.net/kernel/index/
+
+除此之外，内核开发人员的一个宝贵资源是：
+
+        http://kernelnewbies.org/
+
+当然，我们不应该忘记 http://kernel.org/ 这是内核发布信息的最终位置。
+
+关于内核开发有很多书：
+
+        Linux设备驱动程序，第三版（Jonathan Corbet、Alessandro Rubini和Greg Kroah Hartman）。
+        在线：http://lwn.net/kernel/ldd3/
+
+        Linux内核开发（Robert Love）。
+
+        了解Linux内核（Daniel Bovet和Marco Cesati）。
+
+然而，所有这些书都有一个共同的缺点：当它们上架时，它们往往有些过时，而且它们
+已经上架一段时间了。不过，在那里还可以找到相当多的好信息。
+
+有关git的文档，请访问：
+
+        http://www.kernel.org/pub/software/scm/git/docs/
+
+        http://www.kernel.org/pub/software/scm/git/docs/user-manual.html
+
+结论
+====
+
+祝贺所有通过这篇冗长的文件的人。希望它能够帮助您理解Linux内核是如何开发的，
+以及您如何参与这个过程。
+
+最后，重要的是参与。任何开源软件项目都不超过其贡献者投入其中的总和。Linux内核
+的发展速度和以前一样快，因为它得到了大量开发人员的帮助，他们都在努力使它变得
+更好。内核是一个主要的例子，说明当成千上万的人为了一个共同的目标一起工作时，
+可以做些什么。
+
+不过，内核总是可以从更大的开发人员基础中获益。总有更多的工作要做。但是，同样
+重要的是，Linux生态系统中的大多数其他参与者可以通过为内核做出贡献而受益。使
+代码进入主线是提高代码质量、降低维护和分发成本、提高对内核开发方向的影响程度
+等的关键。这是一种人人都赢的局面。踢开你的编辑，来加入我们吧，你会非常受
+欢迎的。

+Linux内核贡献者契约行为准则解释
+===============================
+
+:ref:`cn_code_of_conduct` 准则是一个通用文档，旨在为几乎所有开源社区提供一套规则。
+每个开源社区都是独一无二的，Linux内核也不例外。因此，本文描述了Linux内核社区中
+如何解释它。我们也不希望这种解释随着时间的推移是静态的，并将根据需要进行调整。
+
+与开发软件的“传统”方法相比，Linux内核开发工作是一个非常个人化的过程。你的贡献
+和背后的想法将被仔细审查，往往导致批判和批评。审查将几乎总是需要改进，材料才
+能包括在内核中。要知道这是因为所有相关人员都希望看到Linux整体成功的最佳解决方
+案。这个开发过程已经被证明可以创建有史以来最健壮的操作系统内核，我们不想做任何
+事情来导致提交质量和最终结果的下降。
+
+维护者
+------
+
+行为准则多次使用“维护者”一词。在内核社区中，“维护者”是负责子系统、驱动程序或
+文件的任何人，并在内核源代码树的维护者文件中列出。
+
+责任
+----
+
+《行为准则》提到了维护人员的权利和责任，这需要进一步澄清。
+
+首先，最重要的是，有一个合理的期望是由维护人员通过实例来领导。
+
+也就是说，我们的社区是广阔的，对维护者没有新的要求，他们单方面处理其他人在
+他们活跃的社区的行为。这一责任由我们所有人承担，最终《行为准则》记录了最终的
+上诉路径，以防有关行为问题的问题悬而未决。
+
+维护人员应该愿意在出现问题时提供帮助，并在需要时与社区中的其他人合作。如果您
+不确定如何处理出现的情况，请不要害怕联系技术咨询委员会（TAB）或其他维护人员。
+除非您愿意，否则不会将其视为违规报告。如果您不确定是否该联系TAB 或任何其他维
+护人员，请联系我们的冲突调解人 Mishi Choudhary <mishi@linux.com>。
+
+最后，“善待对方”才是每个人的最终目标。我们知道每个人都是人，有时我们都会失败，
+但我们所有人的首要目标应该是努力友好地解决问题。执行行为准则将是最后的选择。
+
+我们的目标是创建一个强大的、技术先进的操作系统，以及所涉及的技术复杂性，这自
+然需要专业知识和决策。
+
+所需的专业知识因贡献领域而异。它主要由上下文和技术复杂性决定，其次由贡献者和
+维护者的期望决定。
+
+专家的期望和决策都要经过讨论，但在最后，为了取得进展，必须能够做出决策。这一
+特权掌握在维护人员和项目领导的手中，预计将善意使用。
+
+因此，设定专业知识期望、作出决定和拒绝不适当的贡献不被视为违反行为准则。
+
+虽然维护人员一般都欢迎新来者，但他们帮助（新）贡献者克服障碍的能力有限，因此
+他们必须确定优先事项。这也不应被视为违反了行为准则。内核社区意识到这一点，并
+以各种形式提供入门级节目，如 kernelnewbies.org 。
+
+范围
+----
+
+Linux内核社区主要在一组公共电子邮件列表上进行交互，这些列表分布在由多个不同
+公司或个人控制的多个不同服务器上。所有这些列表都在内核源代码树中的
+MAINTAINERS 文件中定义。发送到这些邮件列表的任何电子邮件都被视为包含在行为
+准则中。
+
+使用 kernel.org bugzilla和其他子系统bugzilla 或bug跟踪工具的开发人员应该遵循
+行为准则的指导原则。Linux内核社区没有“官方”项目电子邮件地址或“官方”社交媒体
+地址。使用kernel.org电子邮件帐户执行的任何活动必须遵循为kernel.org发布的行为
+准则，就像任何使用公司电子邮件帐户的个人必须遵循该公司的特定规则一样。
+
+行为准则并不禁止在邮件列表消息、内核更改日志消息或代码注释中继续包含名称、
+电子邮件地址和相关注释。
+
+其他论坛中的互动包括在适用于上述论坛的任何规则中，通常不包括在行为准则中。
+除了在极端情况下可考虑的例外情况。
+
+提交给内核的贡献应该使用适当的语言。在行为准则之前已经存在的内容现在不会被
+视为违反。然而，不适当的语言可以被视为一个bug；如果任何相关方提交补丁，
+这样的bug将被更快地修复。当前属于用户/内核API的一部分的表达式，或者反映已
+发布标准或规范中使用的术语的表达式，不被视为bug。
+
+执行
+----
+
+行为准则中列出的地址属于行为准则委员会。https://kernel.org/code-of-conduct.html
+列出了在任何给定时间接收这些电子邮件的确切成员。成员不能访问在加入委员会之前
+或离开委员会之后所做的报告。
+
+最初的行为准则委员会由TAB的志愿者以及作为中立第三方的专业调解人组成。委员会
+的首要任务是建立文件化的流程，并将其公开。
+
+如果报告人不希望将整个委员会纳入投诉或关切，可直接联系委员会的任何成员，包括
+调解人。
+
+行为准则委员会根据流程审查案例（见上文），并根据需要和适当与TAB协商，例如请求
+和接收有关内核社区的信息。
+
+委员会做出的任何决定都将提交到表中，以便在必要时与相关维护人员一起执行。行为
+准则委员会的决定可以通过三分之二的投票推翻。
+
+每季度，行为准则委员会和标签将提供一份报告，概述行为准则委员会收到的匿名报告
+及其状态，以及任何否决决定的细节，包括完整和可识别的投票细节。
+
+我们希望在启动期之后为行为准则委员会人员配备建立一个不同的流程。发生此情况时，
+将使用该信息更新此文档。

+Linux 内核代码风格
+=========================
+
+这是一个简短的文档，描述了 linux 内核的首选代码风格。代码风格是因人而异的，
+而且我不愿意把自己的观点强加给任何人，但这就像我去做任何事情都必须遵循的原则
+那样，我也希望在绝大多数事上保持这种的态度。请 (在写代码时) 至少考虑一下这里
+的代码风格。
+
+首先，我建议你打印一份 GNU 代码规范，然后不要读。烧了它，这是一个具有重大象征
+性意义的动作。
+
+不管怎样，现在我们开始：
+
+
+1) 缩进
+--------------
+
+制表符是 8 个字符，所以缩进也是 8 个字符。有些异端运动试图将缩进变为 4 (甚至
+2！) 字符深，这几乎相当于尝试将圆周率的值定义为 3。
+
+理由：缩进的全部意义就在于清楚的定义一个控制块起止于何处。尤其是当你盯着你的
+屏幕连续看了 20 小时之后，你将会发现大一点的缩进会使你更容易分辨缩进。
+
+现在，有些人会抱怨 8 个字符的缩进会使代码向右边移动的太远，在 80 个字符的终端
+屏幕上就很难读这样的代码。这个问题的答案是，如果你需要 3 级以上的缩进，不管用
+何种方式你的代码已经有问题了，应该修正你的程序。
+
+简而言之，8 个字符的缩进可以让代码更容易阅读，还有一个好处是当你的函数嵌套太
+深的时候可以给你警告。留心这个警告。
+
+在 switch 语句中消除多级缩进的首选的方式是让 ``switch`` 和从属于它的 ``case``
+标签对齐于同一列，而不要 ``两次缩进`` ``case`` 标签。比如：
+
+.. code-block:: c
+
+	switch (suffix) {
+	case 'G':
+	case 'g':
+		mem <<= 30;
+		break;
+	case 'M':
+	case 'm':
+		mem <<= 20;
+		break;
+	case 'K':
+	case 'k':
+		mem <<= 10;
+		/* fall through */
+	default:
+		break;
+	}
+
+不要把多个语句放在一行里，除非你有什么东西要隐藏：
+
+.. code-block:: c
+
+	if (condition) do_this;
+	  do_something_everytime;
+
+也不要在一行里放多个赋值语句。内核代码风格超级简单。就是避免可能导致别人误读
+的表达式。
+
+除了注释、文档和 Kconfig 之外，不要使用空格来缩进，前面的例子是例外，是有意为
+之。
+
+选用一个好的编辑器，不要在行尾留空格。
+
+
+2) 把长的行和字符串打散
+------------------------------
+
+代码风格的意义就在于使用平常使用的工具来维持代码的可读性和可维护性。
+
+每一行的长度的限制是 80 列，我们强烈建议您遵守这个惯例。
+
+长于 80 列的语句要打散成有意义的片段。除非超过 80 列能显著增加可读性，并且不
+会隐藏信息。子片段要明显短于母片段，并明显靠右。这同样适用于有着很长参数列表
+的函数头。然而，绝对不要打散对用户可见的字符串，例如 printk 信息，因为这样就
+很难对它们 grep。
+
+
+3) 大括号和空格的放置
+------------------------------
+
+C 语言风格中另外一个常见问题是大括号的放置。和缩进大小不同，选择或弃用某种放
+置策略并没有多少技术上的原因，不过首选的方式，就像 Kernighan 和 Ritchie 展示
+给我们的，是把起始大括号放在行尾，而把结束大括号放在行首，所以：
+
+.. code-block:: c
+
+	if (x is true) {
+		we do y
+	}
+
+这适用于所有的非函数语句块 (if, switch, for, while, do)。比如：
+
+.. code-block:: c
+
+	switch (action) {
+	case KOBJ_ADD:
+		return "add";
+	case KOBJ_REMOVE:
+		return "remove";
+	case KOBJ_CHANGE:
+		return "change";
+	default:
+		return NULL;
+	}
+
+不过，有一个例外，那就是函数：函数的起始大括号放置于下一行的开头，所以：
+
+.. code-block:: c
+
+	int function(int x)
+	{
+		body of function
+	}
+
+全世界的异端可能会抱怨这个不一致性是... 呃... 不一致的，不过所有思维健全的人
+都知道 (a) K&R 是 **正确的** 并且 (b) K&R 是正确的。此外，不管怎样函数都是特
+殊的 (C 函数是不能嵌套的)。
+
+注意结束大括号独自占据一行，除非它后面跟着同一个语句的剩余部分，也就是 do 语
+句中的 "while" 或者 if 语句中的 "else"，像这样：
+
+.. code-block:: c
+
+	do {
+		body of do-loop
+	} while (condition);
+
+和
+
+.. code-block:: c
+
+	if (x == y) {
+		..
+	} else if (x > y) {
+		...
+	} else {
+		....
+	}
+
+理由：K&R。
+
+也请注意这种大括号的放置方式也能使空 (或者差不多空的) 行的数量最小化，同时不
+失可读性。因此，由于你的屏幕上的新行是不可再生资源 (想想 25 行的终端屏幕)，你
+将会有更多的空行来放置注释。
+
+当只有一个单独的语句的时候，不用加不必要的大括号。
+
+.. code-block:: c
+
+	if (condition)
+		action();
+
+和
+
+.. code-block:: c
+
+	if (condition)
+		do_this();
+	else
+		do_that();
+
+这并不适用于只有一个条件分支是单语句的情况；这时所有分支都要使用大括号：
+
+.. code-block:: c
+
+	if (condition) {
+		do_this();
+		do_that();
+	} else {
+		otherwise();
+	}
+
+3.1) 空格
+********************
+
+Linux 内核的空格使用方式 (主要) 取决于它是用于函数还是关键字。(大多数) 关键字
+后要加一个空格。值得注意的例外是 sizeof, typeof, alignof 和 __attribute__，这
+些关键字某些程度上看起来更像函数 (它们在 Linux 里也常常伴随小括号而使用，尽管
+在 C 里这样的小括号不是必需的，就像 ``struct fileinfo info;`` 声明过后的
+``sizeof info``)。
+
+所以在这些关键字之后放一个空格::
+
+	if, switch, case, for, do, while
+
+但是不要在 sizeof, typeof, alignof 或者 __attribute__ 这些关键字之后放空格。
+例如，
+
+.. code-block:: c
+
+	s = sizeof(struct file);
+
+不要在小括号里的表达式两侧加空格。这是一个 **反例** ：
+
+.. code-block:: c
+
+	s = sizeof( struct file );
+
+当声明指针类型或者返回指针类型的函数时， ``*`` 的首选使用方式是使之靠近变量名
+或者函数名，而不是靠近类型名。例子：
+
+.. code-block:: c
+
+	char *linux_banner;
+	unsigned long long memparse(char *ptr, char **retptr);
+	char *match_strdup(substring_t *s);
+
+在大多数二元和三元操作符两侧使用一个空格，例如下面所有这些操作符::
+
+	=  +  -  <  >  *  /  %  |  &  ^  <=  >=  ==  !=  ?  :
+
+但是一元操作符后不要加空格::
+
+	&  *  +  -  ~  !  sizeof  typeof  alignof  __attribute__  defined
+
+后缀自加和自减一元操作符前不加空格::
+
+	++  --
+
+前缀自加和自减一元操作符后不加空格::
+
+	++  --
+
+``.`` 和 ``->`` 结构体成员操作符前后不加空格。
+
+不要在行尾留空白。有些可以自动缩进的编辑器会在新行的行首加入适量的空白，然后
+你就可以直接在那一行输入代码。不过假如你最后没有在那一行输入代码，有些编辑器
+就不会移除已经加入的空白，就像你故意留下一个只有空白的行。包含行尾空白的行就
+这样产生了。
+
+当 git 发现补丁包含了行尾空白的时候会警告你，并且可以应你的要求去掉行尾空白；
+不过如果你是正在打一系列补丁，这样做会导致后面的补丁失败，因为你改变了补丁的
+上下文。
+
+
+4) 命名
+------------------------------
+
+C 是一个简朴的语言，你的命名也应该这样。和 Modula-2 和 Pascal 程序员不同，
+C 程序员不使用类似 ThisVariableIsATemporaryCounter 这样华丽的名字。C 程序员会
+称那个变量为 ``tmp`` ，这样写起来会更容易，而且至少不会令其难于理解。
+
+不过，虽然混用大小写的名字是不提倡使用的，但是全局变量还是需要一个具描述性的
+名字。称一个全局函数为 ``foo`` 是一个难以饶恕的错误。
+
+全局变量 (只有当你 **真正** 需要它们的时候再用它) 需要有一个具描述性的名字，就
+像全局函数。如果你有一个可以计算活动用户数量的函数，你应该叫它
+``count_active_users()`` 或者类似的名字，你不应该叫它 ``cntuser()`` 。
+
+在函数名中包含函数类型 (所谓的匈牙利命名法) 是脑子出了问题——编译器知道那些类
+型而且能够检查那些类型，这样做只能把程序员弄糊涂了。难怪微软总是制造出有问题
+的程序。
+
+本地变量名应该简短，而且能够表达相关的含义。如果你有一些随机的整数型的循环计
+数器，它应该被称为 ``i`` 。叫它 ``loop_counter`` 并无益处，如果它没有被误解的
+可能的话。类似的， ``tmp`` 可以用来称呼任意类型的临时变量。
+
+如果你怕混淆了你的本地变量名，你就遇到另一个问题了，叫做函数增长荷尔蒙失衡综
+合症。请看第六章 (函数)。
+
+
+5) Typedef
+-----------
+
+不要使用类似 ``vps_t`` 之类的东西。
+
+对结构体和指针使用 typedef 是一个 **错误** 。当你在代码里看到：
+
+.. code-block:: c
+
+	vps_t a;
+
+这代表什么意思呢？
+
+相反，如果是这样
+
+.. code-block:: c
+
+	struct virtual_container *a;
+
+你就知道 ``a`` 是什么了。
+
+很多人认为 typedef ``能提高可读性`` 。实际不是这样的。它们只在下列情况下有用：
+
+ (a) 完全不透明的对象 (这种情况下要主动使用 typedef 来 **隐藏** 这个对象实际上
+     是什么)。
+
+     例如： ``pte_t`` 等不透明对象，你只能用合适的访问函数来访问它们。
+
+     .. note::
+
+       不透明性和 "访问函数" 本身是不好的。我们使用 pte_t 等类型的原因在于真
+       的是完全没有任何共用的可访问信息。
+
+ (b) 清楚的整数类型，如此，这层抽象就可以 **帮助** 消除到底是 ``int`` 还是
+     ``long`` 的混淆。
+
+     u8/u16/u32 是完全没有问题的 typedef，不过它们更符合类别 (d) 而不是这里。
+
+     .. note::
+
+       要这样做，必须事出有因。如果某个变量是 ``unsigned long`` ，那么没有必要
+
+	typedef unsigned long myflags_t;
+
+     不过如果有一个明确的原因，比如它在某种情况下可能会是一个 ``unsigned int``
+     而在其他情况下可能为 ``unsigned long`` ，那么就不要犹豫，请务必使用
+     typedef。
+
+ (c) 当你使用 sparse 按字面的创建一个 **新** 类型来做类型检查的时候。
+
+ (d) 和标准 C99 类型相同的类型，在某些例外的情况下。
+
+     虽然让眼睛和脑筋来适应新的标准类型比如 ``uint32_t`` 不需要花很多时间，可
+     是有些人仍然拒绝使用它们。
+
+     因此，Linux 特有的等同于标准类型的 ``u8/u16/u32/u64`` 类型和它们的有符号
+     类型是被允许的——尽管在你自己的新代码中，它们不是强制要求要使用的。
+
+     当编辑已经使用了某个类型集的已有代码时，你应该遵循那些代码中已经做出的选
+     择。
+
+ (e) 可以在用户空间安全使用的类型。
+
+     在某些用户空间可见的结构体里，我们不能要求 C99 类型而且不能用上面提到的
+     ``u32`` 类型。因此，我们在与用户空间共享的所有结构体中使用 __u32 和类似
+     的类型。
+
+可能还有其他的情况，不过基本的规则是 **永远不要** 使用 typedef，除非你可以明
+确的应用上述某个规则中的一个。
+
+总的来说，如果一个指针或者一个结构体里的元素可以合理的被直接访问到，那么它们
+就不应该是一个 typedef。
+
+
+6) 函数
+------------------------------
+
+函数应该简短而漂亮，并且只完成一件事情。函数应该可以一屏或者两屏显示完 (我们
+都知道 ISO/ANSI 屏幕大小是 80x24)，只做一件事情，而且把它做好。
+
+一个函数的最大长度是和该函数的复杂度和缩进级数成反比的。所以，如果你有一个理
+论上很简单的只有一个很长 (但是简单) 的 case 语句的函数，而且你需要在每个 case
+里做很多很小的事情，这样的函数尽管很长，但也是可以的。
+
+不过，如果你有一个复杂的函数，而且你怀疑一个天分不是很高的高中一年级学生可能
+甚至搞不清楚这个函数的目的，你应该严格遵守前面提到的长度限制。使用辅助函数，
+并为之取个具描述性的名字 (如果你觉得它们的性能很重要的话，可以让编译器内联它
+们，这样的效果往往会比你写一个复杂函数的效果要好。)
+
+函数的另外一个衡量标准是本地变量的数量。此数量不应超过 5－10 个，否则你的函数
+就有问题了。重新考虑一下你的函数，把它分拆成更小的函数。人的大脑一般可以轻松
+的同时跟踪 7 个不同的事物，如果再增多的话，就会糊涂了。即便你聪颖过人，你也可
+能会记不清你 2 个星期前做过的事情。
+
+在源文件里，使用空行隔开不同的函数。如果该函数需要被导出，它的 **EXPORT** 宏
+应该紧贴在它的结束大括号之下。比如：
+
+.. code-block:: c
+
+	int system_is_up(void)
+	{
+		return system_state == SYSTEM_RUNNING;
+	}
+	EXPORT_SYMBOL(system_is_up);
+
+在函数原型中，包含函数名和它们的数据类型。虽然 C 语言里没有这样的要求，在
+Linux 里这是提倡的做法，因为这样可以很简单的给读者提供更多的有价值的信息。
+
+
+7) 集中的函数退出途径
+------------------------------
+
+虽然被某些人声称已经过时，但是 goto 语句的等价物还是经常被编译器所使用，具体
+形式是无条件跳转指令。
+
+当一个函数从多个位置退出，并且需要做一些类似清理的常见操作时，goto 语句就很方
+便了。如果并不需要清理操作，那么直接 return 即可。
+
+选择一个能够说明 goto 行为或它为何存在的标签名。如果 goto 要释放 ``buffer``,
+一个不错的名字可以是 ``out_free_buffer:`` 。别去使用像 ``err1:`` 和 ``err2:``
+这样的GW_BASIC 名称，因为一旦你添加或删除了 (函数的) 退出路径，你就必须对它们
+重新编号，这样会难以去检验正确性。
+
+使用 goto 的理由是：
+
+- 无条件语句容易理解和跟踪
+- 嵌套程度减小
+- 可以避免由于修改时忘记更新个别的退出点而导致错误
+- 让编译器省去删除冗余代码的工作 ;)
+
+.. code-block:: c
+
+	int fun(int a)
+	{
+		int result = 0;
+		char *buffer;
+
+		buffer = kmalloc(SIZE, GFP_KERNEL);
+		if (!buffer)
+			return -ENOMEM;
+
+		if (condition1) {
+			while (loop1) {
+				...
+			}
+			result = 1;
+			goto out_free_buffer;
+		}
+		...
+	out_free_buffer:
+		kfree(buffer);
+		return result;
+	}
+
+一个需要注意的常见错误是 ``一个 err 错误`` ，就像这样：
+
+.. code-block:: c
+
+	err:
+		kfree(foo->bar);
+		kfree(foo);
+		return ret;
+
+这段代码的错误是，在某些退出路径上 ``foo`` 是 NULL。通常情况下，通过把它分离
+成两个错误标签 ``err_free_bar:`` 和 ``err_free_foo:`` 来修复这个错误：
+
+.. code-block:: c
+
+	 err_free_bar:
+		kfree(foo->bar);
+	 err_free_foo:
+		kfree(foo);
+		return ret;
+
+理想情况下，你应该模拟错误来测试所有退出路径。
+
+
+8) 注释
+------------------------------
+
+注释是好的，不过有过度注释的危险。永远不要在注释里解释你的代码是如何运作的：
+更好的做法是让别人一看你的代码就可以明白，解释写的很差的代码是浪费时间。
+
+一般的，你想要你的注释告诉别人你的代码做了什么，而不是怎么做的。也请你不要把
+注释放在一个函数体内部：如果函数复杂到你需要独立的注释其中的一部分，你很可能
+需要回到第六章看一看。你可以做一些小注释来注明或警告某些很聪明 (或者槽糕) 的
+做法，但不要加太多。你应该做的，是把注释放在函数的头部，告诉人们它做了什么，
+也可以加上它做这些事情的原因。
+
+当注释内核 API 函数时，请使用 kernel-doc 格式。请看
+Documentation/doc-guide/ 和 scripts/kernel-doc 以获得详细信息。
+
+长 (多行) 注释的首选风格是：
+
+.. code-block:: c
+
+	/*
+	 * This is the preferred style for multi-line
+	 * comments in the Linux kernel source code.
+	 * Please use it consistently.
+	 *
+	 * Description:  A column of asterisks on the left side,
+	 * with beginning and ending almost-blank lines.
+	 */
+
+对于在 net/ 和 drivers/net/ 的文件，首选的长 (多行) 注释风格有些不同。
+
+.. code-block:: c
+
+	/* The preferred comment style for files in net/ and drivers/net
+	 * looks like this.
+	 *
+	 * It is nearly the same as the generally preferred comment style,
+	 * but there is no initial almost-blank line.
+	 */
+
+注释数据也是很重要的，不管是基本类型还是衍生类型。为了方便实现这一点，每一行
+应只声明一个数据 (不要使用逗号来一次声明多个数据)。这样你就有空间来为每个数据
+写一段小注释来解释它们的用途了。
+
+
+9) 你已经把事情弄糟了
+------------------------------
+
+这没什么，我们都是这样。可能你的使用了很长时间 Unix 的朋友已经告诉你
+``GNU emacs`` 能自动帮你格式化 C 源代码，而且你也注意到了，确实是这样，不过它
+所使用的默认值和我们想要的相去甚远 (实际上，甚至比随机打的还要差——无数个猴子
+在 GNU emacs 里打字永远不会创造出一个好程序) (译注：Infinite Monkey Theorem)
+
+所以你要么放弃 GNU emacs，要么改变它让它使用更合理的设定。要采用后一个方案，
+你可以把下面这段粘贴到你的 .emacs 文件里。
+
+.. code-block:: none
+
+  (defun c-lineup-arglist-tabs-only (ignored)
+    "Line up argument lists by tabs, not spaces"
+    (let* ((anchor (c-langelem-pos c-syntactic-element))
+           (column (c-langelem-2nd-pos c-syntactic-element))
+           (offset (- (1+ column) anchor))
+           (steps (floor offset c-basic-offset)))
+      (* (max steps 1)
+         c-basic-offset)))
+
+  (dir-locals-set-class-variables
+   'linux-kernel
+   '((c-mode . (
+          (c-basic-offset . 8)
+          (c-label-minimum-indentation . 0)
+          (c-offsets-alist . (
+                  (arglist-close         . c-lineup-arglist-tabs-only)
+                  (arglist-cont-nonempty .
+		      (c-lineup-gcc-asm-reg c-lineup-arglist-tabs-only))
+                  (arglist-intro         . +)
+                  (brace-list-intro      . +)
+                  (c                     . c-lineup-C-comments)
+                  (case-label            . 0)
+                  (comment-intro         . c-lineup-comment)
+                  (cpp-define-intro      . +)
+                  (cpp-macro             . -1000)
+                  (cpp-macro-cont        . +)
+                  (defun-block-intro     . +)
+                  (else-clause           . 0)
+                  (func-decl-cont        . +)
+                  (inclass               . +)
+                  (inher-cont            . c-lineup-multi-inher)
+                  (knr-argdecl-intro     . 0)
+                  (label                 . -1000)
+                  (statement             . 0)
+                  (statement-block-intro . +)
+                  (statement-case-intro  . +)
+                  (statement-cont        . +)
+                  (substatement          . +)
+                  ))
+          (indent-tabs-mode . t)
+          (show-trailing-whitespace . t)
+          ))))
+
+  (dir-locals-set-directory-class
+   (expand-file-name "~/src/linux-trees")
+   'linux-kernel)
+
+这会让 emacs 在 ``~/src/linux-trees`` 下的 C 源文件获得更好的内核代码风格。
+
+不过就算你尝试让 emacs 正确的格式化代码失败了，也并不意味着你失去了一切：还可
+以用 ``indent`` 。
+
+不过，GNU indent 也有和 GNU emacs 一样有问题的设定，所以你需要给它一些命令选
+项。不过，这还不算太糟糕，因为就算是 GNU indent 的作者也认同 K&R 的权威性
+(GNU 的人并不是坏人，他们只是在这个问题上被严重的误导了)，所以你只要给 indent
+指定选项 ``-kr -i8`` (代表 ``K&R，8 字符缩进``)，或使用 ``scripts/Lindent``
+这样就可以以最时髦的方式缩进源代码。
+
+``indent`` 有很多选项，特别是重新格式化注释的时候，你可能需要看一下它的手册。
+不过记住： ``indent`` 不能修正坏的编程习惯。
+
+
+10) Kconfig 配置文件
+------------------------------
+
+对于遍布源码树的所有 Kconfig* 配置文件来说，它们缩进方式有所不同。紧挨着
+``config`` 定义的行，用一个制表符缩进，然而 help 信息的缩进则额外增加 2 个空
+格。举个例子::
+
+  config AUDIT
+	bool "Auditing support"
+	depends on NET
+	help
+	  Enable auditing infrastructure that can be used with another
+	  kernel subsystem, such as SELinux (which requires this for
+	  logging of avc messages output).  Does not do system-call
+	  auditing without CONFIG_AUDITSYSCALL.
+
+而那些危险的功能 (比如某些文件系统的写支持) 应该在它们的提示字符串里显著的声
+明这一点::
+
+  config ADFS_FS_RW
+	bool "ADFS write support (DANGEROUS)"
+	depends on ADFS_FS
+	...
+
+要查看配置文件的完整文档，请看 Documentation/kbuild/kconfig-language.txt。
+
+
+11) 数据结构
+------------------------------
+
+如果一个数据结构，在创建和销毁它的单线执行环境之外可见，那么它必须要有一个引
+用计数器。内核里没有垃圾收集 (并且内核之外的垃圾收集慢且效率低下)，这意味着你
+绝对需要记录你对这种数据结构的使用情况。
+
+引用计数意味着你能够避免上锁，并且允许多个用户并行访问这个数据结构——而不需要
+担心这个数据结构仅仅因为暂时不被使用就消失了，那些用户可能不过是沉睡了一阵或
+者做了一些其他事情而已。
+
+注意上锁 **不能** 取代引用计数。上锁是为了保持数据结构的一致性，而引用计数是一
+个内存管理技巧。通常二者都需要，不要把两个搞混了。
+
+很多数据结构实际上有 2 级引用计数，它们通常有不同 ``类`` 的用户。子类计数器统
+计子类用户的数量，每当子类计数器减至零时，全局计数器减一。
+
+这种 ``多级引用计数`` 的例子可以在内存管理 (``struct mm_struct``: mm_users 和
+mm_count)，和文件系统 (``struct super_block``: s_count 和 s_active) 中找到。
+
+记住：如果另一个执行线索可以找到你的数据结构，但这个数据结构没有引用计数器，
+这里几乎肯定是一个 bug。
+
+
+12) 宏，枚举和RTL
+------------------------------
+
+用于定义常量的宏的名字及枚举里的标签需要大写。
+
+.. code-block:: c
+
+	#define CONSTANT 0x12345
+
+在定义几个相关的常量时，最好用枚举。
+
+宏的名字请用大写字母，不过形如函数的宏的名字可以用小写字母。
+
+一般的，如果能写成内联函数就不要写成像函数的宏。
+
+含有多个语句的宏应该被包含在一个 do-while 代码块里：
+
+.. code-block:: c
+
+	#define macrofun(a, b, c)			\
+		do {					\
+			if (a == 5)			\
+				do_this(b, c);		\
+		} while (0)
+
+使用宏的时候应避免的事情：
+
+1) 影响控制流程的宏：
+
+.. code-block:: c
+
+	#define FOO(x)					\
+		do {					\
+			if (blah(x) < 0)		\
+				return -EBUGGERED;	\
+		} while (0)
+
+**非常** 不好。它看起来像一个函数，不过却能导致 ``调用`` 它的函数退出；不要打
+乱读者大脑里的语法分析器。
+
+2) 依赖于一个固定名字的本地变量的宏：
+
+.. code-block:: c
+
+	#define FOO(val) bar(index, val)
+
+可能看起来像是个不错的东西，不过它非常容易把读代码的人搞糊涂，而且容易导致看起
+来不相关的改动带来错误。
+
+3) 作为左值的带参数的宏： FOO(x) = y；如果有人把 FOO 变成一个内联函数的话，这
+   种用法就会出错了。
+
+4) 忘记了优先级：使用表达式定义常量的宏必须将表达式置于一对小括号之内。带参数
+   的宏也要注意此类问题。
+
+.. code-block:: c
+
+	#define CONSTANT 0x4000
+	#define CONSTEXP (CONSTANT | 3)
+
+5) 在宏里定义类似函数的本地变量时命名冲突：
+
+.. code-block:: c
+
+	#define FOO(x)				\
+	({					\
+		typeof(x) ret;			\
+		ret = calc_ret(x);		\
+		(ret);				\
+	})
+
+ret 是本地变量的通用名字 - __foo_ret 更不容易与一个已存在的变量冲突。
+
+cpp 手册对宏的讲解很详细。gcc internals 手册也详细讲解了 RTL，内核里的汇编语
+言经常用到它。
+
+
+13) 打印内核消息
+------------------------------
+
+内核开发者应该是受过良好教育的。请一定注意内核信息的拼写，以给人以好的印象。
+不要用不规范的单词比如 ``dont``，而要用 ``do not`` 或者 ``don't`` 。保证这些信
+息简单明了,无歧义。
+
+内核信息不必以英文句号结束。
+
+在小括号里打印数字 (%d) 没有任何价值，应该避免这样做。
+
+<linux/device.h> 里有一些驱动模型诊断宏，你应该使用它们，以确保信息对应于正确
+的设备和驱动，并且被标记了正确的消息级别。这些宏有：dev_err(), dev_warn(),
+dev_info() 等等。对于那些不和某个特定设备相关连的信息，<linux/printk.h> 定义
+了 pr_notice(), pr_info(), pr_warn(), pr_err() 和其他。
+
+写出好的调试信息可以是一个很大的挑战；一旦你写出后，这些信息在远程除错时能提
+供极大的帮助。然而打印调试信息的处理方式同打印非调试信息不同。其他 pr_XXX()
+函数能无条件地打印，pr_debug() 却不；默认情况下它不会被编译，除非定义了 DEBUG
+或设定了 CONFIG_DYNAMIC_DEBUG。实际这同样是为了 dev_dbg()，一个相关约定是在一
+个已经开启了 DEBUG 时，使用 VERBOSE_DEBUG 来添加 dev_vdbg()。
+
+许多子系统拥有 Kconfig 调试选项来开启 -DDEBUG 在对应的 Makefile 里面；在其他
+情况下，特殊文件使用 #define DEBUG。当一条调试信息需要被无条件打印时，例如，
+如果已经包含一个调试相关的 #ifdef 条件，printk(KERN_DEBUG ...) 就可被使用。
+
+
+14) 分配内存
+------------------------------
+
+内核提供了下面的一般用途的内存分配函数：
+kmalloc(), kzalloc(), kmalloc_array(), kcalloc(), vmalloc() 和 vzalloc()。
+请参考 API 文档以获取有关它们的详细信息。
+
+传递结构体大小的首选形式是这样的：
+
+.. code-block:: c
+
+	p = kmalloc(sizeof(*p), ...);
+
+另外一种传递方式中，sizeof 的操作数是结构体的名字，这样会降低可读性，并且可能
+会引入 bug。有可能指针变量类型被改变时，而对应的传递给内存分配函数的 sizeof
+的结果不变。
+
+强制转换一个 void 指针返回值是多余的。C 语言本身保证了从 void 指针到其他任何
+指针类型的转换是没有问题的。
+
+分配一个数组的首选形式是这样的：
+
+.. code-block:: c
+
+	p = kmalloc_array(n, sizeof(...), ...);
+
+分配一个零长数组的首选形式是这样的：
+
+.. code-block:: c
+
+	p = kcalloc(n, sizeof(...), ...);
+
+两种形式检查分配大小 n * sizeof(...) 的溢出，如果溢出返回 NULL。
+
+
+15) 内联弊病
+------------------------------
+
+有一个常见的误解是 ``内联`` 是 gcc 提供的可以让代码运行更快的一个选项。虽然使
+用内联函数有时候是恰当的 (比如作为一种替代宏的方式，请看第十二章)，不过很多情
+况下不是这样。inline 的过度使用会使内核变大，从而使整个系统运行速度变慢。
+因为体积大内核会占用更多的指令高速缓存，而且会导致 pagecache 的可用内存减少。
+想象一下，一次 pagecache 未命中就会导致一次磁盘寻址，将耗时 5 毫秒。5 毫秒的
+时间内 CPU 能执行很多很多指令。
+
+一个基本的原则是如果一个函数有 3 行以上，就不要把它变成内联函数。这个原则的一
+个例外是，如果你知道某个参数是一个编译时常量，而且因为这个常量你确定编译器在
+编译时能优化掉你的函数的大部分代码，那仍然可以给它加上 inline 关键字。
+kmalloc() 内联函数就是一个很好的例子。
+
+人们经常主张给 static 的而且只用了一次的函数加上 inline，如此不会有任何损失，
+因为没有什么好权衡的。虽然从技术上说这是正确的，但是实际上这种情况下即使不加
+inline gcc 也可以自动使其内联。而且其他用户可能会要求移除 inline，由此而来的
+争论会抵消 inline 自身的潜在价值，得不偿失。
+
+
+16) 函数返回值及命名
+------------------------------
+
+函数可以返回多种不同类型的值，最常见的一种是表明函数执行成功或者失败的值。这样
+的一个值可以表示为一个错误代码整数 (-Exxx＝失败，0＝成功) 或者一个 ``成功``
+布尔值 (0＝失败，非0＝成功)。
+
+混合使用这两种表达方式是难于发现的 bug 的来源。如果 C 语言本身严格区分整形和
+布尔型变量，那么编译器就能够帮我们发现这些错误... 不过 C 语言不区分。为了避免
+产生这种 bug，请遵循下面的惯例::
+
+	如果函数的名字是一个动作或者强制性的命令，那么这个函数应该返回错误代
+	码整数。如果是一个判断，那么函数应该返回一个 "成功" 布尔值。
+
+比如， ``add work`` 是一个命令，所以 add_work() 在成功时返回 0，在失败时返回
+-EBUSY。类似的，因为 ``PCI device present`` 是一个判断，所以 pci_dev_present()
+在成功找到一个匹配的设备时应该返回 1，如果找不到时应该返回 0。
+
+所有 EXPORTed 函数都必须遵守这个惯例，所有的公共函数也都应该如此。私有
+(static) 函数不需要如此，但是我们也推荐这样做。
+
+返回值是实际计算结果而不是计算是否成功的标志的函数不受此惯例的限制。一般的，
+他们通过返回一些正常值范围之外的结果来表示出错。典型的例子是返回指针的函数，
+他们使用 NULL 或者 ERR_PTR 机制来报告错误。
+
+
+17) 不要重新发明内核宏
+------------------------------
+
+头文件 include/linux/kernel.h 包含了一些宏，你应该使用它们，而不要自己写一些
+它们的变种。比如，如果你需要计算一个数组的长度，使用这个宏
+
+.. code-block:: c
+
+	#define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))
+
+类似的，如果你要计算某结构体成员的大小，使用
+
+.. code-block:: c
+
+	#define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f))
+
+还有可以做严格的类型检查的 min() 和 max() 宏，如果你需要可以使用它们。你可以
+自己看看那个头文件里还定义了什么你可以拿来用的东西，如果有定义的话，你就不应
+在你的代码里自己重新定义。
+
+
+18) 编辑器模式行和其他需要罗嗦的事情
+--------------------------------------------------
+
+有一些编辑器可以解释嵌入在源文件里的由一些特殊标记标明的配置信息。比如，emacs
+能够解释被标记成这样的行：
+
+.. code-block:: c
+
+	-*- mode: c -*-
+
+或者这样的：
+
+.. code-block:: c
+
+	/*
+	Local Variables:
+	compile-command: "gcc -DMAGIC_DEBUG_FLAG foo.c"
+	End:
+	*/
+
+Vim 能够解释这样的标记：
+
+.. code-block:: c
+
+	/* vim:set sw=8 noet */
+
+不要在源代码中包含任何这样的内容。每个人都有他自己的编辑器配置，你的源文件不
+应该覆盖别人的配置。这包括有关缩进和模式配置的标记。人们可以使用他们自己定制
+的模式，或者使用其他可以产生正确的缩进的巧妙方法。
+
+
+19) 内联汇编
+------------------------------
+
+在特定架构的代码中，你可能需要内联汇编与 CPU 和平台相关功能连接。需要这么做时
+就不要犹豫。然而，当 C 可以完成工作时，不要平白无故地使用内联汇编。在可能的情
+况下，你可以并且应该用 C 和硬件沟通。
+
+请考虑去写捆绑通用位元 (wrap common bits) 的内联汇编的简单辅助函数，别去重复
+地写下只有细微差异内联汇编。记住内联汇编可以使用 C 参数。
+
+大型，有一定复杂度的汇编函数应该放在 .S 文件内，用相应的 C 原型定义在 C 头文
+件中。汇编函数的 C 原型应该使用 ``asmlinkage`` 。
+
+你可能需要把汇编语句标记为 volatile，用来阻止 GCC 在没发现任何副作用后就把它
+移除了。你不必总是这样做，尽管，这不必要的举动会限制优化。
+
+在写一个包含多条指令的单个内联汇编语句时，把每条指令用引号分割而且各占一行，
+除了最后一条指令外，在每个指令结尾加上 \n\t，让汇编输出时可以正确地缩进下一条
+指令：
+
+.. code-block:: c
+
+	asm ("magic %reg1, #42\n\t"
+	     "more_magic %reg2, %reg3"
+	     : /* outputs */ : /* inputs */ : /* clobbers */);
+
+
+20) 条件编译
+------------------------------
+
+只要可能，就不要在 .c 文件里面使用预处理条件 (#if, #ifdef)；这样做让代码更难
+阅读并且更难去跟踪逻辑。替代方案是，在头文件中用预处理条件提供给那些 .c 文件
+使用，再给 #else 提供一个空桩 (no-op stub) 版本，然后在 .c 文件内无条件地调用
+那些 (定义在头文件内的) 函数。这样做，编译器会避免为桩函数 (stub) 的调用生成
+任何代码，产生的结果是相同的，但逻辑将更加清晰。
+
+最好倾向于编译整个函数，而不是函数的一部分或表达式的一部分。与其放一个 ifdef
+在表达式内，不如分解出部分或全部表达式，放进一个单独的辅助函数，并应用预处理
+条件到这个辅助函数内。
+
+如果你有一个在特定配置中，可能变成未使用的函数或变量，编译器会警告它定义了但
+未使用，把它标记为 __maybe_unused 而不是将它包含在一个预处理条件中。(然而，如
+果一个函数或变量总是未使用，就直接删除它。)
+
+在代码中，尽可能地使用 IS_ENABLED 宏来转化某个 Kconfig 标记为 C 的布尔
+表达式，并在一般的 C 条件中使用它：
+
+.. code-block:: c
+
+	if (IS_ENABLED(CONFIG_SOMETHING)) {
+		...
+	}
+
+编译器会做常量折叠，然后就像使用 #ifdef 那样去包含或排除代码块，所以这不会带
+来任何运行时开销。然而，这种方法依旧允许 C 编译器查看块内的代码，并检查它的正
+确性 (语法，类型，符号引用，等等)。因此，如果条件不满足，代码块内的引用符号就
+不存在时，你还是必须去用 #ifdef。
+
+在任何有意义的 #if 或 #ifdef 块的末尾 (超过几行的)，在 #endif 同一行的后面写下
+注解，注释这个条件表达式。例如：
+
+.. code-block:: c
+
+	#ifdef CONFIG_SOMETHING
+	...
+	#endif /* CONFIG_SOMETHING */

+
+Linux邮件客户端配置信息
+=======================
+
+Git
+---
+
+现在大多数开发人员使用 ``git send-email`` 而不是常规的电子邮件客户端。这方面
+的手册非常好。在接收端，维护人员使用 ``git am`` 加载补丁。
+
+如果你是 ``git`` 新手，那么把你的第一个补丁发送给你自己。将其保存为包含所有
+标题的原始文本。运行 ``git am raw_email.txt`` ，然后使用 ``git log`` 查看更
+改日志。如果工作正常，再将补丁发送到相应的邮件列表。
+
+
+普通配置
+--------
+Linux内核补丁是通过邮件被提交的，最好把补丁作为邮件体的内嵌文本。有些维护者
+接收附件，但是附件的内容格式应该是"text/plain"。然而，附件一般是不赞成的，
+因为这会使补丁的引用部分在评论过程中变的很困难。
+
+用来发送Linux内核补丁的邮件客户端在发送补丁时应该处于文本的原始状态。例如，
+他们不能改变或者删除制表符或者空格，甚至是在每一行的开头或者结尾。
+
+不要通过"format=flowed"模式发送补丁。这样会引起不可预期以及有害的断行。
+
+不要让你的邮件客户端进行自动换行。这样也会破坏你的补丁。
+
+邮件客户端不能改变文本的字符集编码方式。要发送的补丁只能是ASCII或者UTF-8编码方式，
+如果你使用UTF-8编码方式发送邮件，那么你将会避免一些可能发生的字符集问题。
+
+邮件客户端应该形成并且保持 References: 或者 In-Reply-To: 标题，那么
+邮件话题就不会中断。
+
+复制粘帖(或者剪贴粘帖)通常不能用于补丁，因为制表符会转换为空格。使用xclipboard, xclip
+或者xcutsel也许可以，但是最好测试一下或者避免使用复制粘帖。
+
+不要在使用PGP/GPG署名的邮件中包含补丁。这样会使得很多脚本不能读取和适用于你的补丁。
+（这个问题应该是可以修复的）
+
+在给内核邮件列表发送补丁之前，给自己发送一个补丁是个不错的主意，保存接收到的
+邮件，将补丁用'patch'命令打上，如果成功了，再给内核邮件列表发送。
+
+
+一些邮件客户端提示
+------------------
+这里给出一些详细的MUA配置提示，可以用于给Linux内核发送补丁。这些并不意味是
+所有的软件包配置总结。
+
+说明：
+TUI = 以文本为基础的用户接口
+GUI = 图形界面用户接口
+
+Alpine (TUI)
+~~~~~~~~~~~~
+
+配置选项：
+在"Sending Preferences"部分：
+
+- "Do Not Send Flowed Text"必须开启
+- "Strip Whitespace Before Sending"必须关闭
+
+当写邮件时，光标应该放在补丁会出现的地方，然后按下CTRL-R组合键，使指定的
+补丁文件嵌入到邮件中。
+
+Evolution (GUI)
+~~~~~~~~~~~~~~~
+
+一些开发者成功的使用它发送补丁
+
+当选择邮件选项：Preformat
+  从Format->Heading->Preformatted (Ctrl-7)或者工具栏
+
+然后使用：
+  Insert->Text File... (Alt-n x)插入补丁文件。
+
+你还可以"diff -Nru old.c new.c | xclip"，选择Preformat，然后使用中间键进行粘帖。
+
+Kmail (GUI)
+~~~~~~~~~~~
+
+一些开发者成功的使用它发送补丁。
+
+默认设置不为HTML格式是合适的；不要启用它。
+
+当书写一封邮件的时候，在选项下面不要选择自动换行。唯一的缺点就是你在邮件中输入的任何文本
+都不会被自动换行，因此你必须在发送补丁之前手动换行。最简单的方法就是启用自动换行来书写邮件，
+然后把它保存为草稿。一旦你在草稿中再次打开它，它已经全部自动换行了，那么你的邮件虽然没有
+选择自动换行，但是还不会失去已有的自动换行。
+
+在邮件的底部，插入补丁之前，放上常用的补丁定界符：三个连字号(---)。
+
+然后在"Message"菜单条目，选择插入文件，接着选取你的补丁文件。还有一个额外的选项，你可以
+通过它配置你的邮件建立工具栏菜单，还可以带上"insert file"图标。
+
+你可以安全地通过GPG标记附件，但是内嵌补丁最好不要使用GPG标记它们。作为内嵌文本的签发补丁，
+当从GPG中提取7位编码时会使他们变的更加复杂。
+
+如果你非要以附件的形式发送补丁，那么就右键点击附件，然后选中属性，突出"Suggest automatic
+display"，这样内嵌附件更容易让读者看到。
+
+当你要保存将要发送的内嵌文本补丁，你可以从消息列表窗格选择包含补丁的邮件，然后右击选择
+"save as"。你可以使用一个没有更改的包含补丁的邮件，如果它是以正确的形式组成。当你正真在它
+自己的窗口之下察看，那时没有选项可以保存邮件--已经有一个这样的bug被汇报到了kmail的bugzilla
+并且希望这将会被处理。邮件是以只针对某个用户可读写的权限被保存的，所以如果你想把邮件复制到其他地方，
+你不得不把他们的权限改为组或者整体可读。
+
+Lotus Notes (GUI)
+~~~~~~~~~~~~~~~~~
+
+不要使用它。
+
+Mutt (TUI)
+~~~~~~~~~~
+
+很多Linux开发人员使用mutt客户端，所以证明它肯定工作的非常漂亮。
+
+Mutt不自带编辑器，所以不管你使用什么编辑器都不应该带有自动断行。大多数编辑器都带有
+一个"insert file"选项，它可以通过不改变文件内容的方式插入文件。
+
+'vim'作为mutt的编辑器：
+  set editor="vi"
+
+  如果使用xclip，敲入以下命令
+  :set paste
+  按中键之前或者shift-insert或者使用
+  :r filename
+
+如果想要把补丁作为内嵌文本。
+(a)ttach工作的很好，不带有"set paste"。
+
+你可以通过 ``git format-patch`` 生成补丁，然后用 Mutt发送它们::
+
+        $ mutt -H 0001-some-bug-fix.patch
+
+配置选项：
+它应该以默认设置的形式工作。
+然而，把"send_charset"设置为"us-ascii::utf-8"也是一个不错的主意。
+
+Mutt 是高度可配置的。 这里是个使用mutt通过 Gmail 发送的补丁的最小配置::
+
+  # .muttrc
+  # ================  IMAP ====================
+  set imap_user = 'yourusername@gmail.com'
+  set imap_pass = 'yourpassword'
+  set spoolfile = imaps://imap.gmail.com/INBOX
+  set folder = imaps://imap.gmail.com/
+  set record="imaps://imap.gmail.com/[Gmail]/Sent Mail"
+  set postponed="imaps://imap.gmail.com/[Gmail]/Drafts"
+  set mbox="imaps://imap.gmail.com/[Gmail]/All Mail"
+
+  # ================  SMTP  ====================
+  set smtp_url = "smtp://username@smtp.gmail.com:587/"
+  set smtp_pass = $imap_pass
+  set ssl_force_tls = yes # Require encrypted connection
+
+  # ================  Composition  ====================
+  set editor = `echo \$EDITOR`
+  set edit_headers = yes  # See the headers when editing
+  set charset = UTF-8     # value of $LANG; also fallback for send_charset
+  # Sender, email address, and sign-off line must match
+  unset use_domain        # because joe@localhost is just embarrassing
+  set realname = "YOUR NAME"
+  set from = "username@gmail.com"
+  set use_from = yes
+
+Mutt文档含有更多信息:
+
+    http://dev.mutt.org/trac/wiki/UseCases/Gmail
+
+    http://dev.mutt.org/doc/manual.html
+
+Pine (TUI)
+~~~~~~~~~~
+
+Pine过去有一些空格删减问题，但是这些现在应该都被修复了。
+
+如果可以，请使用alpine(pine的继承者)
+
+配置选项：
+- 最近的版本需要消除流程文本
+- "no-strip-whitespace-before-send"选项也是需要的。
+
+
+Sylpheed (GUI)
+~~~~~~~~~~~~~~
+
+- 内嵌文本可以很好的工作（或者使用附件）。
+- 允许使用外部的编辑器。
+- 对于目录较多时非常慢。
+- 如果通过non-SSL连接，无法使用TLS SMTP授权。
+- 在组成窗口中有一个很有用的ruler bar。
+- 给地址本中添加地址就不会正确的了解显示名。
+
+Thunderbird (GUI)
+~~~~~~~~~~~~~~~~~
+
+默认情况下，thunderbird很容易损坏文本，但是还有一些方法可以强制它变得更好。
+
+- 在用户帐号设置里，组成和寻址，不要选择"Compose messages in HTML format"。
+
+- 编辑你的Thunderbird配置设置来使它不要拆行使用：user_pref("mailnews.wraplength", 0);
+
+- 编辑你的Thunderbird配置设置，使它不要使用"format=flowed"格式：user_pref("mailnews.
+  send_plaintext_flowed", false);
+
+- 你需要使Thunderbird变为预先格式方式：
+  如果默认情况下你书写的是HTML格式，那不是很难。仅仅从标题栏的下拉框中选择"Preformat"格式。
+  如果默认情况下你书写的是文本格式，你不得把它改为HTML格式（仅仅作为一次性的）来书写新的消息，
+  然后强制使它回到文本格式，否则它就会拆行。要实现它，在写信的图标上使用shift键来使它变为HTML
+  格式，然后标题栏的下拉框中选择"Preformat"格式。
+
+- 允许使用外部的编辑器：
+  针对Thunderbird打补丁最简单的方法就是使用一个"external editor"扩展，然后使用你最喜欢的
+  $EDITOR来读取或者合并补丁到文本中。要实现它，可以下载并且安装这个扩展，然后添加一个使用它的
+  按键View->Toolbars->Customize...最后当你书写信息的时候仅仅点击它就可以了。
+
+TkRat (GUI)
+~~~~~~~~~~~
+
+可以使用它。使用"Insert file..."或者外部的编辑器。
+
+Gmail (Web GUI)
+~~~~~~~~~~~~~~~
+
+不要使用它发送补丁。
+
+Gmail网页客户端自动地把制表符转换为空格。
+
+虽然制表符转换为空格问题可以被外部编辑器解决，同时它还会使用回车换行把每行拆分为78个字符。
+
+另一个问题是Gmail还会把任何不是ASCII的字符的信息改为base64编码。它把东西变的像欧洲人的名字。
+
+                                ###

+如何参与Linux内核开发
+=====================
+
+这是一篇将如何参与Linux内核开发的相关问题一网打尽的终极秘笈。它将指导你
+成为一名Linux内核开发者，并且学会如何同Linux内核开发社区合作。它尽可能不
+包括任何关于内核编程的技术细节，但会给你指引一条获得这些知识的正确途径。
+
+如果这篇文章中的任何内容不再适用，请给文末列出的文件维护者发送补丁。
+
+
+入门
+----
+
+你想了解如何成为一名Linux内核开发者？或者老板吩咐你“给这个设备写个Linux
+驱动程序”？这篇文章的目的就是教会你达成这些目标的全部诀窍，它将描述你需
+要经过的流程以及给出如何同内核社区合作的一些提示。它还将试图解释内核社区
+为何这样运作。
+
+Linux内核大部分是由C语言写成的，一些体系结构相关的代码用到了汇编语言。要
+参与内核开发，你必须精通C语言。除非你想为某个架构开发底层代码，否则你并
+不需要了解（任何体系结构的）汇编语言。下面列举的书籍虽然不能替代扎实的C
+语言教育和多年的开发经验，但如果需要的话，做为参考还是不错的：
+
+ - "The C Programming Language" by Kernighan and Ritchie [Prentice Hall]
+   《C程序设计语言（第2版·新版）》（徐宝文 李志 译）[机械工业出版社]

+Linux内核使用GNU C和GNU工具链开发。虽然它遵循ISO C89标准，但也用到了一些
+标准中没有定义的扩展。内核是自给自足的C环境，不依赖于标准C库的支持，所以
+并不支持C标准中的部分定义。比如long long类型的大数除法和浮点运算就不允许
+使用。有时候确实很难弄清楚内核对工具链的要求和它所使用的扩展，不幸的是目
+前还没有明确的参考资料可以解释它们。请查阅gcc信息页（使用“info gcc”命令
+显示）获得一些这方面信息。
+
+请记住你是在学习怎么和已经存在的开发社区打交道。它由一群形形色色的人组成，
+他们对代码、风格和过程有着很高的标准。这些标准是在长期实践中总结出来的，
+适应于地理上分散的大型开发团队。它们已经被很好得整理成档，建议你在开发
+之前尽可能多的学习这些标准，而不要期望别人来适应你或者你公司的行为方式。

+
+法律问题
+--------
+
+Linux内核源代码都是在GPL（通用公共许可证）的保护下发布的。要了解这种许可
+的细节请查看源代码主目录下的COPYING文件。Linux内核许可准则和如何使用
+`SPDX <https://spdx.org/>` 标志符说明在这个文件中
+:ref:`Documentation/translations/zh_CN/process/license-rules.rst <cn_kernel_licensing>`
+如果你对它还有更深入问题请联系律师，而不要在Linux内核邮件组上提问。因为
+邮件组里的人并不是律师，不要期望他们的话有法律效力。

+
+文档
+----
+
+Linux内核代码中包含有大量的文档。这些文档对于学习如何与内核社区互动有着
+不可估量的价值。当一个新的功能被加入内核，最好把解释如何使用这个功能的文
+档也放进内核。当内核的改动导致面向用户空间的接口发生变化时，最好将相关信
+息或手册页(manpages)的补丁发到mtk.manpages@gmail.com，以向手册页(manpages)
+的维护者解释这些变化。
+
+以下是内核代码中需要阅读的文档：
+  :ref:`Documentation/admin-guide/README.rst <readme>`
+    文件简要介绍了Linux内核的背景，并且描述了如何配置和编译内核。内核的
+    新用户应该从这里开始。
+
+
+  :ref:`Documentation/process/changes.rst <changes>`
+    文件给出了用来编译和使用内核所需要的最小软件包列表。
+
+  :ref:`Documentation/translations/zh_CN/process/coding-style.rst <cn_codingstyle>`
+    描述Linux内核的代码风格和理由。所有新代码需要遵守这篇文档中定义的规
+    范。大多数维护者只会接收符合规定的补丁，很多人也只会帮忙检查符合风格
+    的代码。
+
+  :ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`
+  :ref:`Documentation/process/submitting-drivers.rst <submittingdrivers>`
+
+    这两份文档明确描述如何创建和发送补丁，其中包括（但不仅限于)：
+       - 邮件内容
+       - 邮件格式
+       - 选择收件人
+
+    遵守这些规定并不能保证提交成功（因为所有补丁需要通过严格的内容和风格
+    审查），但是忽视他们几乎就意味着失败。
+
+    其他关于如何正确地生成补丁的优秀文档包括：
+    "The Perfect Patch"
+
+        http://www.ozlabs.org/~akpm/stuff/tpp.txt
+
+    "Linux kernel patch submission format"
+
+        http://linux.yyz.us/patch-format.html
+
+  :ref:`Documentation/translations/zh_CN/process/stable-api-nonsense.rst <cn_stable_api_nonsense>`
+    论证内核为什么特意不包括稳定的内核内部API，也就是说不包括像这样的特
+    性：
+
+       - 子系统中间层（为了兼容性？）
+       - 在不同操作系统间易于移植的驱动程序
+       - 减缓（甚至阻止）内核代码的快速变化
+
+    这篇文档对于理解Linux的开发哲学至关重要。对于将开发平台从其他操作系
+    统转移到Linux的人来说也很重要。
+
+  :ref:`Documentation/admin-guide/security-bugs.rst <securitybugs>`
+    如果你认为自己发现了Linux内核的安全性问题，请根据这篇文档中的步骤来
+    提醒其他内核开发者并帮助解决这个问题。
+
+  :ref:`Documentation/translations/zh_CN/process/management-style.rst <cn_managementstyle>`
+
+    描述内核维护者的工作方法及其共有特点。这对于刚刚接触内核开发（或者对
+    它感到好奇）的人来说很重要，因为它解释了很多对于内核维护者独特行为的
+    普遍误解与迷惑。
+
+  :ref:`Documentation/process/stable-kernel-rules.rst <stable_kernel_rules>`
+    解释了稳定版内核发布的规则，以及如何将改动放入这些版本的步骤。
+
+  :ref:`Documentation/process/kernel-docs.rst <kernel_docs>`
+    有助于内核开发的外部文档列表。如果你在内核自带的文档中没有找到你想找
+    的内容，可以查看这些文档。
+
+  :ref:`Documentation/process/applying-patches.rst <applying_patches>`
+    关于补丁是什么以及如何将它打在不同内核开发分支上的好介绍
+
+内核还拥有大量从代码自动生成的文档。它包含内核内部API的全面介绍以及如何
+妥善处理加锁的规则。生成的文档会放在 Documentation/DocBook/目录下。在内
+核源码的主目录中使用以下不同命令将会分别生成PDF、Postscript、HTML和手册
+页等不同格式的文档::
+
+    make pdfdocs
+    make htmldocs
+
+
+如何成为内核开发者
+------------------
+如果你对Linux内核开发一无所知，你应该访问“Linux内核新手”计划：
+
+	http://kernelnewbies.org
+
+它拥有一个可以问各种最基本的内核开发问题的邮件列表（在提问之前一定要记得
+查找已往的邮件，确认是否有人已经回答过相同的问题）。它还拥有一个可以获得
+实时反馈的IRC聊天频道，以及大量对于学习Linux内核开发相当有帮助的文档。
+
+网站简要介绍了源代码组织结构、子系统划分以及目前正在进行的项目（包括内核
+中的和单独维护的）。它还提供了一些基本的帮助信息，比如如何编译内核和打补
+丁。
+
+如果你想加入内核开发社区并协助完成一些任务，却找不到从哪里开始，可以访问
+“Linux内核房管员”计划：
+
+	http://kernelnewbies.org/KernelJanitors
+
+这是极佳的起点。它提供一个相对简单的任务列表，列出内核代码中需要被重新
+整理或者改正的地方。通过和负责这个计划的开发者们一同工作，你会学到将补丁
+集成进内核的基本原理。如果还没有决定下一步要做什么的话，你还可能会得到方
+向性的指点。
+
+在真正动手修改内核代码之前，理解要修改的代码如何运作是必需的。要达到这个
+目的，没什么办法比直接读代码更有效了（大多数花招都会有相应的注释），而且
+一些特制的工具还可以提供帮助。例如，“Linux代码交叉引用”项目就是一个值得
+特别推荐的帮助工具，它将源代码显示在有编目和索引的网页上。其中一个更新及
+时的内核源码库，可以通过以下地址访问：
+
+        https://elixir.bootlin.com/
+
+
+开发流程
+--------
+
+目前Linux内核开发流程包括几个“主内核分支”和很多子系统相关的内核分支。这
+些分支包括：
+
+  - Linus 的内核源码树
+  - 多个主要版本的稳定版内核树
+  - 子系统相关的内核树
+  - linux-next 集成测试树
+
+
+主线树
+------
+主线树是由Linus Torvalds 维护的。你可以在https://kernel.org 网站或者代码
+库中下找到它。它的开发遵循以下步骤：
+
+  - 每当一个新版本的内核被发布，为期两周的集成窗口将被打开。在这段时间里
+    维护者可以向Linus提交大段的修改，通常这些修改已经被放到-mm内核中几个
+    星期了。提交大量修改的首选方式是使用git工具（内核的代码版本管理工具
+    ，更多的信息可以在 http://git-scm.com/ 获取），不过使用普通补丁也是
+    可以的。
+  - 两个星期以后-rc1版本内核发布。之后只有不包含可能影响整个内核稳定性的
+    新功能的补丁才可能被接受。请注意一个全新的驱动程序（或者文件系统）有
+    可能在-rc1后被接受是因为这样的修改完全独立，不会影响其他的代码，所以
+    没有造成内核退步的风险。在-rc1以后也可以用git向Linus提交补丁，不过所
+    有的补丁需要同时被发送到相应的公众邮件列表以征询意见。
+  - 当Linus认为当前的git源码树已经达到一个合理健全的状态足以发布供人测试
+    时，一个新的-rc版本就会被发布。计划是每周都发布新的-rc版本。
+  - 这个过程一直持续下去直到内核被认为达到足够稳定的状态，持续时间大概是
+    6个星期。
+
+关于内核发布，值得一提的是Andrew Morton在linux-kernel邮件列表中如是说：
+	“没有人知道新内核何时会被发布，因为发布是根据已知bug的情况来决定
+	的，而不是根据一个事先制定好的时间表。”
+
+子系统特定树
+------------
+
+各种内核子系统的维护者——以及许多内核子系统开发人员——在源代码库中公开了他们
+当前的开发状态。这样，其他人就可以看到内核的不同区域发生了什么。在开发速度
+很快的领域，可能会要求开发人员将提交的内容建立在这样的子系统内核树上，这样
+就避免了提交与其他已经进行的工作之间的冲突。
+
+这些存储库中的大多数都是Git树，但是也有其他的scm在使用，或者补丁队列被发布
+为Quilt系列。这些子系统存储库的地址列在MAINTAINERS文件中。其中许多可以在
+https://git.kernel.org/上浏览。
+
+在将一个建议的补丁提交到这样的子系统树之前，需要对它进行审查，审查主要发生
+在邮件列表上（请参见下面相应的部分）。对于几个内核子系统，这个审查过程是通
+过工具补丁跟踪的。Patchwork提供了一个Web界面，显示补丁发布、对补丁的任何评
+论或修订，维护人员可以将补丁标记为正在审查、接受或拒绝。大多数补丁网站都列
+在 https://patchwork.kernel.org/
+
+Linux-next 集成测试树
+---------------------
+
+在将子系统树的更新合并到主线树之前，需要对它们进行集成测试。为此，存在一个
+特殊的测试存储库，其中几乎每天都会提取所有子系统树：
+
+        https://git.kernel.org/？p=linux/kernel/git/next/linux-next.git
+
+通过这种方式，Linux-next 对下一个合并阶段将进入主线内核的内容给出了一个概要
+展望。非常欢冒险的测试者运行测试Linux-next。
+
+多个主要版本的稳定版内核树
+-----------------------------------
+由3个数字组成的内核版本号说明此内核是-stable版本。它们包含内核的相对较小且
+至关重要的修补，这些修补针对安全性问题或者严重的内核退步。
+
+这种版本的内核适用于那些期望获得最新的稳定版内核并且不想参与测试开发版或
+者实验版的用户。
+
+稳定版内核树版本由“稳定版”小组（邮件地址<stable@vger.kernel.org>）维护，一般
+隔周发布新版本。
+
+内核源码中的 :ref:`Documentation/process/stable-kernel-rules.rst <stable_kernel_rules>`
+文件具体描述了可被稳定版内核接受的修改类型以及发布的流程。
+
+
+报告bug
+-------
+
+bugzilla.kernel.org是Linux内核开发者们用来跟踪内核Bug的网站。我们鼓励用
+户在这个工具中报告找到的所有bug。如何使用内核bugzilla的细节请访问：
+
+	http://test.kernel.org/bugzilla/faq.html
+
+内核源码主目录中的:ref:`admin-guide/reporting-bugs.rst <reportingbugs>`
+文件里有一个很好的模板。它指导用户如何报告可能的内核bug以及需要提供哪些信息
+来帮助内核开发者们找到问题的根源。
+
+
+利用bug报告
+-----------
+
+练习内核开发技能的最好办法就是修改其他人报告的bug。你不光可以帮助内核变
+得更加稳定，还可以学会如何解决实际问题从而提高自己的技能，并且让其他开发
+者感受到你的存在。修改bug是赢得其他开发者赞誉的最好办法，因为并不是很多
+人都喜欢浪费时间去修改别人报告的bug。
+
+要尝试修改已知的bug，请访问 http://bugzilla.kernel.org 网址。
+
+
+邮件列表
+--------
+
+正如上面的文档所描述，大多数的骨干内核开发者都加入了Linux Kernel邮件列
+表。如何订阅和退订列表的细节可以在这里找到：
+
+	http://vger.kernel.org/vger-lists.html#linux-kernel
+
+网上很多地方都有这个邮件列表的存档(archive)。可以使用搜索引擎来找到这些
+存档。比如：
+
+	http://dir.gmane.org/gmane.linux.kernel
+
+在发信之前，我们强烈建议你先在存档中搜索你想要讨论的问题。很多已经被详细
+讨论过的问题只在邮件列表的存档中可以找到。
+
+大多数内核子系统也有自己独立的邮件列表来协调各自的开发工作。从
+MAINTAINERS文件中可以找到不同话题对应的邮件列表。
+
+很多邮件列表架设在kernel.org服务器上。这些列表的信息可以在这里找到：
+
+	http://vger.kernel.org/vger-lists.html
+
+在使用这些邮件列表时，请记住保持良好的行为习惯。下面的链接提供了与这些列
+表（或任何其它邮件列表）交流的一些简单规则，虽然内容有点滥竽充数。
+
+	http://www.albion.com/netiquette/
+
+当有很多人回复你的邮件时，邮件的抄送列表会变得很长。请不要将任何人从抄送
+列表中删除，除非你有足够的理由这么做。也不要只回复到邮件列表。请习惯于同
+一封邮件接收两次（一封来自发送者一封来自邮件列表），而不要试图通过添加一
+些奇特的邮件头来解决这个问题，人们不会喜欢的。
+
+记住保留你所回复内容的上下文和源头。在你回复邮件的顶部保留“某某某说到……”
+这几行。将你的评论加在被引用的段落之间而不要放在邮件的顶部。
+
+如果你在邮件中附带补丁，请确认它们是可以直接阅读的纯文本（如
+:ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`
+文档中所述）。内核开发者们不希望遇到附件或者被压缩了的补丁。只有这样才能
+保证他们可以直接评论你的每行代码。请确保你使用的邮件发送程序不会修改空格
+和制表符。一个防范性的测试方法是先将邮件发送给自己，然后自己尝试是否可以
+顺利地打上收到的补丁。如果测试不成功，请调整或者更换你的邮件发送程序直到
+它正确工作为止。
+
+总而言之，请尊重其他的邮件列表订阅者。
+
+
+同内核社区合作
+----------------
+
+内核社区的目标就是提供尽善尽美的内核。所以当你提交补丁期望被接受进内核的
+时候，它的技术价值以及其他方面都将被评审。那么你可能会得到什么呢？
+
+  - 批评
+  - 评论
+  - 要求修改
+  - 要求证明修改的必要性
+  - 沉默
+
+要记住，这些是把补丁放进内核的正常情况。你必须学会听取对补丁的批评和评论，
+从技术层面评估它们，然后要么重写你的补丁要么简明扼要地论证修改是不必要
+的。如果你发的邮件没有得到任何回应，请过几天后再试一次，因为有时信件会湮
+没在茫茫信海中。
+
+你不应该做的事情：
+
+  - 期望自己的补丁不受任何质疑就直接被接受
+  - 翻脸
+  - 忽略别人的评论
+  - 没有按照别人的要求做任何修改就重新提交
+
+在一个努力追寻最好技术方案的社区里，对于一个补丁有多少好处总会有不同的见
+解。你必须要抱着合作的态度，愿意改变自己的观点来适应内核的风格。或者至少
+愿意去证明你的想法是有价值的。记住，犯错误是允许的，只要你愿意朝着正确的
+方案去努力。
+
+如果你的第一个补丁换来的是一堆修改建议，这是很正常的。这并不代表你的补丁
+不会被接受，也不意味着有人和你作对。你只需要改正所有提出的问题然后重新发
+送你的补丁。
+
+内核社区和公司文化的差异
+------------------------
+
+内核社区的工作模式同大多数传统公司开发队伍的工作模式并不相同。下面这些例
+子，可以帮助你避免某些可能发生问题：
+用这些话介绍你的修改提案会有好处：
+
+    - 它同时解决了多个问题
+    - 它删除了2000行代码
+    - 这是补丁，它已经解释了我想要说明的
+    - 我在5种不同的体系结构上测试过它……
+    - 这是一系列小补丁用来……
+    - 这个修改提高了普通机器的性能……
+
+应该避免如下的说法：
+
+    - 我们在AIX/ptx/Solaris就是这么做的，所以这么做肯定是好的……
+    - 我做这行已经20年了，所以……
+    - 为了我们公司赚钱考虑必须这么做
+    - 这是我们的企业产品线所需要的
+    - 这里是描述我观点的1000页设计文档
+    - 这是一个5000行的补丁用来……
+    - 我重写了现在乱七八糟的代码，这就是……
+    - 我被规定了最后期限，所以这个补丁需要立刻被接受
+
+另外一个内核社区与大部分传统公司的软件开发队伍不同的地方是无法面对面地交
+流。使用电子邮件和IRC聊天工具做为主要沟通工具的一个好处是性别和种族歧视
+将会更少。Linux内核的工作环境更能接受妇女和少数族群，因为每个人在别人眼
+里只是一个邮件地址。国际化也帮助了公平的实现，因为你无法通过姓名来判断人
+的性别。男人有可能叫李丽，女人也有可能叫王刚。大多数在Linux内核上工作过
+并表达过看法的女性对在linux上工作的经历都给出了正面的评价。
+
+对于一些不习惯使用英语的人来说，语言可能是一个引起问题的障碍。在邮件列表
+中要正确地表达想法必需良好地掌握语言，所以建议你在发送邮件之前最好检查一
+下英文写得是否正确。
+
+
+拆分修改
+--------
+
+Linux内核社区并不喜欢一下接收大段的代码。修改需要被恰当地介绍、讨论并且
+拆分成独立的小段。这几乎完全和公司中的习惯背道而驰。你的想法应该在开发最
+开始的阶段就让大家知道，这样你就可以及时获得对你正在进行的开发的反馈。这
+样也会让社区觉得你是在和他们协作，而不是仅仅把他们当作倾销新功能的对象。
+无论如何，你不要一次性地向邮件列表发送50封信，你的补丁序列应该永远用不到
+这么多。
+
+将补丁拆开的原因如下：
+
+1) 小的补丁更有可能被接受，因为它们不需要太多的时间和精力去验证其正确性。
+   一个5行的补丁，可能在维护者看了一眼以后就会被接受。而500行的补丁则
+   需要数个小时来审查其正确性（所需时间随补丁大小增加大约呈指数级增长）。
+
+   当出了问题的时候，小的补丁也会让调试变得非常容易。一个一个补丁地回溯
+   将会比仔细剖析一个被打上的大补丁（这个补丁破坏了其他东西）容易得多。
+
+2）不光发送小的补丁很重要，在提交之前重新编排、化简（或者仅仅重新排列）
+   补丁也是很重要的。
+
+这里有内核开发者Al Viro打的一个比方：
+	“想象一个老师正在给学生批改数学作业。老师并不希望看到学生为了得
+	到正确解法所进行的尝试和产生的错误。他希望看到的是最干净最优雅的
+	解答。好学生了解这点，绝不会把最终解决之前的中间方案提交上去。”
+
+	内核开发也是这样。维护者和评审者不希望看到一个人在解决问题时的思
+	考过程。他们只希望看到简单和优雅的解决方案。
+
+直接给出一流的解决方案，和社区一起协作讨论尚未完成的工作，这两者之间似乎
+很难找到一个平衡点。所以最好尽早开始收集有利于你进行改进的反馈；同时也要
+保证修改分成很多小块，这样在整个项目都准备好被包含进内核之前，其中的一部
+分可能会先被接收。
+
+必须了解这样做是不可接受的：试图将未完成的工作提交进内核，然后再找时间修
+复。
+
+
+证明修改的必要性
+----------------
+除了将补丁拆成小块，很重要的一点是让Linux社区了解他们为什么需要这样修改。
+你必须证明新功能是有人需要的并且是有用的。
+
+
+记录修改
+--------
+
+当你发送补丁的时候，需要特别留意邮件正文的内容。因为这里的信息将会做为补
+丁的修改记录(ChangeLog)，会被一直保留以备大家查阅。它需要完全地描述补丁，
+包括：
+
+  - 为什么需要这个修改
+  - 补丁的总体设计
+  - 实现细节
+  - 测试结果
+
+想了解它具体应该看起来像什么，请查阅以下文档中的“ChangeLog”章节：
+  “The Perfect Patch”
+  	 http://www.ozlabs.org/~akpm/stuff/tpp.txt
+
+
+这些事情有时候做起来很难。要在任何方面都做到完美可能需要好几年时间。这是
+一个持续提高的过程，它需要大量的耐心和决心。只要不放弃，你一定可以做到。
+很多人已经做到了，而他们都曾经和现在的你站在同样的起点上。

+Linux内核许可规则
+=================
+
+Linux内核根据LICENSES/preferred/GPL-2.0中提供的GNU通用公共许可证版本2
+（GPL-2.0）的条款提供，并在LICENSES/exceptions/Linux-syscall-note中显式
+描述了例外的系统调用，如COPYING文件中所述。
+
+此文档文件提供了如何对每个源文件进行注释以使其许可证清晰明确的说明。
+它不会取代内核的许可证。
+
+内核源代码作为一个整体适用于COPYING文件中描述的许可证，但是单个源文件可以
+具有不同的与GPL-20兼容的许可证::
+
+    GPL-1.0+ : GNU通用公共许可证v1.0或更高版本
+    GPL-2.0+ : GNU通用公共许可证v2.0或更高版本
+    LGPL-2.0 : 仅限GNU库通用公共许可证v2
+    LGPL-2.0+: GNU 库通用公共许可证v2或更高版本
+    LGPL-2.1 : 仅限GNU宽通用公共许可证v2.1
+    LGPL-2.1+: GNU宽通用公共许可证v2.1或更高版本
+
+除此之外，个人文件可以在双重许可下提供，例如一个兼容的GPL变体，或者BSD，
+MIT等许可。
+
+用户空间API（UAPI）头文件描述了用户空间程序与内核的接口，这是一种特殊情况。
+根据内核COPYING文件中的注释，syscall接口是一个明确的边界，它不会将GPL要求
+扩展到任何使用它与内核通信的软件。由于UAPI头文件必须包含在创建在Linux内核
+上运行的可执行文件的任何源文件中，因此此例外必须记录在特别的许可证表述中。
+
+表达源文件许可证的常用方法是将匹配的样板文本添加到文件的顶部注释中。由于
+格式，拼写错误等，这些“样板”很难通过那些在上下文中使用的验证许可证合规性
+的工具。
+
+样板文本的替代方法是在每个源文件中使用软件包数据交换（SPDX）许可证标识符。
+SPDX许可证标识符是机器可解析的，并且是用于提供文件内容的许可证的精确缩写。
+SPDX许可证标识符由Linux 基金会的SPDX 工作组管理，并得到了整个行业，工具
+供应商和法律团队的合作伙伴的一致同意。有关详细信息，请参阅
+https://spdx.org/
+
+Linux内核需要所有源文件中的精确SPDX标识符。内核中使用的有效标识符在
+`许可标识符`_ 一节中进行了解释，并且已可以在
+https://spdx.org/licenses/ 上的官方SPDX许可证列表中检索，并附带许可证
+文本。

+许可标识符语法
+--------------
+
+1.安置:
+
+   内核文件中的SPDX许可证标识符应添加到可包含注释的文件中的第一行。对于大多
+   数文件，这是第一行，除了那些在第一行中需要'#!PATH_TO_INTERPRETER'的脚本。
+   对于这些脚本，SPDX标识符进入第二行。
+
+|
+
+2. 风格:
+
+   SPDX许可证标识符以注释的形式添加。注释样式取决于文件类型::
+
+      C source:	// SPDX-License-Identifier: <SPDX License Expression>
+      C header:	/* SPDX-License-Identifier: <SPDX License Expression> */
+      ASM:	/* SPDX-License-Identifier: <SPDX License Expression> */
+      scripts:	# SPDX-License-Identifier: <SPDX License Expression>
+      .rst:	.. SPDX-License-Identifier: <SPDX License Expression>
+      .dts{i}:	// SPDX-License-Identifier: <SPDX License Expression>
+
+   如果特定工具无法处理标准注释样式，则应使用工具接受的相应注释机制。这是在
+   C 头文件中使用“/\*\*/”样式注释的原因。过去在使用生成的.lds文件中观察到
+   构建被破坏，其中'ld'无法解析C++注释。现在已经解决了这个问题，但仍然有较
+   旧的汇编程序工具无法处理C++样式的注释。
+
+|
+
+3. 句法:
+
+   <SPDX许可证表达式>是SPDX许可证列表中的SPDX短格式许可证标识符，或者在许可
+   证例外适用时由“WITH”分隔的两个SPDX短格式许可证标识符的组合。当应用多个许
+   可证时，表达式由分隔子表达式的关键字“AND”，“OR”组成，并由“（”，“）”包围。
+
+   带有“或更高”选项的[L]GPL等许可证的许可证标识符通过使用“+”来表示“或更高”
+   选项来构建。::
+
+      // SPDX-License-Identifier: GPL-2.0+
+      // SPDX-License-Identifier: LGPL-2.1+
+
+   当需要修正的许可证时，应使用WITH。 例如，linux内核UAPI文件使用表达式::
+
+      // SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
+      // SPDX-License-Identifier: GPL-2.0+ WITH Linux-syscall-note
+
+   其它在内核中使用WITH例外的事例如下::
+
+      // SPDX-License-Identifier: GPL-2.0 WITH mif-exception
+      // SPDX-License-Identifier: GPL-2.0+ WITH GCC-exception-2.0
+
+   例外只能与特定的许可证标识符一起使用。有效的许可证标识符列在异常文本文件
+   的标记中。有关详细信息，请参阅 `许可标识符`_ 一章中的 `例外`_ 。
+
+   如果文件是双重许可且只选择一个许可证，则应使用OR。例如，一些dtsi文件在双
+   许可下可用::
+
+      // SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause
+
+   内核中双许可文件中许可表达式的示例::
+
+      // SPDX-License-Identifier: GPL-2.0 OR MIT
+      // SPDX-License-Identifier: GPL-2.0 OR BSD-2-Clause
+      // SPDX-License-Identifier: GPL-2.0 OR Apache-2.0
+      // SPDX-License-Identifier: GPL-2.0 OR MPL-1.1
+      // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) OR MIT
+      // SPDX-License-Identifier: GPL-1.0+ OR BSD-3-Clause OR OpenSSL
+
+   如果文件具有多个许可证，其条款全部适用于使用该文件，则应使用AND。例如，
+   如果代码是从另一个项目继承的，并且已经授予了将其放入内核的权限，但原始
+   许可条款需要保持有效::
+
+      // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) AND MIT
+
+   另一个需要遵守两套许可条款的例子是::
+
+      // SPDX-License-Identifier: GPL-1.0+ AND LGPL-2.1+
+
+许可标识符
+----------
+
+当前使用的许可证以及添加到内核的代码许可证可以分解为：
+
+1. _`优先许可`:
+
+   应尽可能使用这些许可证，因为它们已知完全兼容并广泛使用。这些许可证在内核
+   目录::
+
+      LICENSES/preferred/
+
+   此目录中的文件包含完整的许可证文本和 `元标记`_ 。文件名与SPDX许可证标识
+   符相同，后者应用于源文件中的许可证。
+
+   例如::
+
+      LICENSES/preferred/GPL-2.0
+
+   包含GPLv2许可证文本和所需的元标签::
+
+      LICENSES/preferred/MIT
+
+   包含MIT许可证文本和所需的元标记
+
+   _`元标记`:
+
+   许可证文件中必须包含以下元标记：
+
+   - Valid-License-Identifier:
+
+     一行或多行, 声明那些许可标识符在项目内有效, 以引用此特定许可的文本。通
+     常这是一个有效的标识符，但是例如对于带有'或更高'选项的许可证，两个标识
+     符都有效。
+
+   - SPDX-URL:
+
+     SPDX页面的URL，其中包含与许可证相关的其他信息.
+
+   - Usage-Guidance:
+
+     使用建议的自由格式文本。该文本必须包含SPDX许可证标识符的正确示例，因为
+     它们应根据 `许可标识符语法`_ 指南放入源文件中。
+
+   - License-Text:
+
+     此标记之后的所有文本都被视为原始许可文本
+
+   文件格式示例::
+
+      Valid-License-Identifier: GPL-2.0
+      Valid-License-Identifier: GPL-2.0+
+      SPDX-URL: https://spdx.org/licenses/GPL-2.0.html
+      Usage-Guide:
+        To use this license in source code, put one of the following SPDX
+	tag/value pairs into a comment according to the placement
+	guidelines in the licensing rules documentation.
+	For 'GNU General Public License (GPL) version 2 only' use:
+	  SPDX-License-Identifier: GPL-2.0
+	For 'GNU General Public License (GPL) version 2 or any later version' use:
+	  SPDX-License-Identifier: GPL-2.0+
+      License-Text:
+        Full license text
+
+   ::
+
+      SPDX-License-Identifier: MIT

+	guidelines in the licensing rules documentation.
+	  SPDX-License-Identifier: MIT
+      License-Text:
+        Full license text
+
+|
+
+2. 不推荐的许可证:
+
+   这些许可证只应用于现有代码或从其他项目导入代码。这些许可证在内核目录::
+
+      LICENSES/other/
+
+   此目录中的文件包含完整的许可证文本和 `元标记`_ 。文件名与SPDX许可证标识
+   符相同，后者应用于源文件中的许可证。
+
+   例如::
+
+      LICENSES/other/ISC
+
+   包含国际系统联合许可文本和所需的元标签::
+
+      LICENSES/other/ZLib
+
+   包含ZLIB许可文本和所需的元标签.
+
+   元标签:
+
+   “其他”许可证的元标签要求与 `优先许可`_ 的要求相同。
+
+   文件格式示例::
+
+      Valid-License-Identifier: ISC
+      SPDX-URL: https://spdx.org/licenses/ISC.html
+      Usage-Guide:
+        Usage of this license in the kernel for new code is discouraged
+	and it should solely be used for importing code from an already
+	existing project.
+        To use this license in source code, put the following SPDX
+	tag/value pair into a comment according to the placement
+	guidelines in the licensing rules documentation.
+	  SPDX-License-Identifier: ISC
+      License-Text:
+        Full license text
+
+|
+
+3. _`例外`:
+
+   某些许可证可以修改，并允许原始许可证不具有的某些例外权利。这些例外在
+   内核目录::
+
+      LICENSES/exceptions/
+
+   此目录中的文件包含完整的例外文本和所需的 `例外元标记`_ 。
+
+   例如::
+
+      LICENSES/exceptions/Linux-syscall-note
+
+   包含Linux内核的COPYING文件中记录的Linux系统调用例外，该文件用于UAPI
+   头文件。例如::
+
+      LICENSES/exceptions/GCC-exception-2.0
+
+   包含GCC'链接例外'，它允许独立于其许可证的任何二进制文件与标记有此例外的
+   文件的编译版本链接。这是从GPL不兼容源代码创建可运行的可执行文件所必需的。
+
+   _`例外元标记`:
+
+   以下元标记必须在例外文件中可用：
+
+   - SPDX-Exception-Identifier:
+
+     一个可与SPDX许可证标识符一起使用的例外标识符。
+
+   - SPDX-URL:
+
+     SPDX页面的URL，其中包含与例外相关的其他信息。
+
+   - SPDX-Licenses:
+
+     以逗号分隔的例外可用的SPDX许可证标识符列表。
+
+   - Usage-Guidance:
+
+     使用建议的自由格式文本。必须在文本后面加上SPDX许可证标识符的正确示例，
+     因为它们应根据 `许可标识符语法`_ 指南放入源文件中。
+
+   - Exception-Text:
+
+     此标记之后的所有文本都被视为原始异常文本
+
+   文件格式示例::
+
+      SPDX-Exception-Identifier: Linux-syscall-note
+      SPDX-URL: https://spdx.org/licenses/Linux-syscall-note.html
+      SPDX-Licenses: GPL-2.0, GPL-2.0+, GPL-1.0+, LGPL-2.0, LGPL-2.0+, LGPL-2.1, LGPL-2.1+
+      Usage-Guidance:
+        This exception is used together with one of the above SPDX-Licenses
+	to mark user-space API (uapi) header files so they can be included
+	into non GPL compliant user-space application code.
+        To use this exception add it with the keyword WITH to one of the
+	identifiers in the SPDX-Licenses tag:
+	  SPDX-License-Identifier: <SPDX-License> WITH Linux-syscall-note
+      Exception-Text:
+        Full exception text
+
+   ::
+
+      SPDX-Exception-Identifier: GCC-exception-2.0
+      SPDX-URL: https://spdx.org/licenses/GCC-exception-2.0.html
+      SPDX-Licenses: GPL-2.0, GPL-2.0+
+      Usage-Guidance:
+        The "GCC Runtime Library exception 2.0" is used together with one
+	of the above SPDX-Licenses for code imported from the GCC runtime
+	library.
+        To use this exception add it with the keyword WITH to one of the
+	identifiers in the SPDX-Licenses tag:
+	  SPDX-License-Identifier: <SPDX-License> WITH GCC-exception-2.0
+      Exception-Text:
+        Full exception text
+
+
+所有SPDX许可证标识符和例外都必须在LICENSES子目录中具有相应的文件。这是允许
+工具验证（例如checkpatch.pl）以及准备好从源读取和提取许可证所必需的, 这是
+各种FOSS组织推荐的，例如 `FSFE REUSE initiative <https://reuse.software/>`_.
+
+_`模块许可`
+-----------------
+
+   可加载内核模块还需要MODULE_LICENSE（）标记。此标记既不替代正确的源代码
+   许可证信息（SPDX-License-Identifier），也不以任何方式表示或确定提供模块
+   源代码的确切许可证。
+
+   此标记的唯一目的是提供足够的信息，该模块是否是自由软件或者是内核模块加
+   载器和用户空间工具的专有模块。
+
+   MODULE_LICENSE（）的有效许可证字符串是:
+
+    ============================= =============================================
+    "GPL"			  模块是根据GPL版本2许可的。这并不表示仅限于
+                                  GPL-2.0或GPL-2.0或更高版本之间的任何区别。
+                                  最正确许可证信息只能通过相应源文件中的许可证
+                                  信息来确定
+
+    "GPL v2"			  和"GPL"相同，它的存在是因为历史原因。
+
+    "GPL and additional rights"   表示模块源在GPL v2变体和MIT许可下双重许可的
+                                  历史变体。请不要在新代码中使用。
+
+    "Dual MIT/GPL"		  表达该模块在GPL v2变体或MIT许可证选择下双重
+                                  许可的正确方式。
+
+    "Dual BSD/GPL"		  该模块根据GPL v2变体或BSD许可证选择进行双重
+                                  许可。 BSD许可证的确切变体只能通过相应源文件
+                                  中的许可证信息来确定。
+
+    "Dual MPL/GPL"		  该模块根据GPL v2变体或Mozilla Public License
+                                  （MPL）选项进行双重许可。 MPL许可证的确切变体
+                                  只能通过相应的源文件中的许可证信息来确定。
+
+    "Proprietary"		  该模块属于专有许可。此字符串仅用于专有的第三
+                                  方模块，不能用于在内核树中具有源代码的模块。
+                                  以这种方式标记的模块在加载时会使用'P'标记污
+                                  染内核，并且内核模块加载器拒绝将这些模块链接
+                                  到使用EXPORT_SYMBOL_GPL（）导出的符号。
+    ============================= =============================================

+Linux 魔术数
+============
+
+这个文件是有关当前使用的魔术值注册表。当你给一个结构添加了一个魔术值，你也应该把这个魔术值添加到这个文件，因为我们最好把用于各种结构的魔术值统一起来。
+
+使用魔术值来保护内核数据结构是一个非常好的主意。这就允许你在运行期检查(a)一个结构是否已经被攻击，或者(b)你已经给一个例行程序通过了一个错误的结构。后一种情况特别地有用---特别是当你通过一个空指针指向结构体的时候。tty源码，例如，经常通过特定驱动使用这种方法并且反复地排列特定方面的结构。
+
+使用魔术值的方法是在结构的开始处声明的，如下::
+
+        struct tty_ldisc {
+	        int	magic;
+        	...
+        };
+
+当你以后给内核添加增强功能的时候，请遵守这条规则！这样就会节省数不清的调试时间，特别是一些古怪的情况，例如，数组超出范围并且重新写了超出部分。遵守这个规则，‪这些情况可以被快速地，安全地避免。

+
+Linux内核管理风格
+=================
+
+这是一个简短的文档，描述了Linux内核首选的（或胡编的，取决于您问谁）管理风格。
+它的目的是在某种程度上参照 :ref:`process/coding-style.rst <codingstyle>`
+主要是为了避免反复回答 [#cnf1]_ 相同（或类似）的问题。
+
+管理风格是非常个人化的，比简单的编码风格规则更难以量化，因此本文档可能与实
+际情况有关，也可能与实际情况无关。起初它是一个玩笑，但这并不意味着它可能不
+是真的。你得自己决定。
+
+顺便说一句，在谈到“核心管理者”时，主要是技术负责人，而不是在公司内部进行传
+统管理的人。如果你签署了采购订单或者对你的团队的预算有任何了解，你几乎肯定
+不是一个核心管理者。这些建议可能适用于您，也可能不适用于您。
+
+首先，我建议你购买“高效人的七个习惯”，而不是阅读它。烧了它，这是一个伟大的
+象征性姿态。
+
+.. [#cnf1] 本文件并不是通过回答问题，而是通过让提问者痛苦地明白，我们不知道
+   答案是什么。
+
+不管怎样，这里是：
+
+.. _decisions:
+
+1）决策
+-------
+
+每个人都认为管理者做决定，而且决策很重要。决定越大越痛苦，管理者就必须越高级。
+这很明显，但事实并非如此。
+
+游戏的名字是 **避免** 做出决定。尤其是，如果有人告诉你“选择（a）或（b），
+我们真的需要你来做决定”，你就是陷入麻烦的管理者。你管理的人比你更了解细节，
+所以如果他们来找你做技术决策，你完蛋了。你显然没有能力为他们做这个决定。
+
+（推论：如果你管理的人不比你更了解细节，你也会被搞砸，尽管原因完全不同。
+也就是说，你的工作是错的，他们应该管理你的才智）
+
+所以游戏的名字是 **避免** 做出决定，至少是那些大而痛苦的决定。做一些小的
+和非结果性的决定是很好的，并且使您看起来好像知道自己在做什么，所以内核管理者
+需要做的是将那些大的和痛苦的决定变成那些没有人真正关心的小事情。
+
+这有助于认识到一个大的决定和一个小的决定之间的关键区别是你是否可以在事后修正
+你的决定。任何决定都可以通过始终确保如果你错了（而且你一定会错），你以后总是
+可以通过回溯来弥补损失。突然间，你就要做两个无关紧要的决定，一个是错误的，另
+一个是正确的。
+
+人们甚至会认为这是真正的领导能力（咳，胡说，咳）。
+
+因此，避免重大决策的关键在于避免做那些无法挽回的事情。不要被引导到一个你无法
+逃离的角落。走投无路的老鼠可能很危险——走投无路的管理者真可怜。
+
+事实证明，由于没有人会愚蠢到让内核管理者承担巨大的财政责任，所以通常很容易
+回溯。既然你不可能浪费掉你无法偿还的巨额资金，你唯一可以回溯的就是技术决策，
+而回溯很容易：只要告诉大家你是个不称职的傻瓜，说对不起，然后撤销你去年让别
+人所做的毫无价值的工作。突然间，你一年前做的决定不在是一个重大的决定，因为
+它很容易被推翻。
+
+事实证明，有些人对接受这种方法有困难，原因有两个：
+
+ - 承认你是个白痴比看起来更难。我们都喜欢保持形象，在公共场合说你错了有时
+   确实很难。
+ - 如果有人告诉你，你去年所做的工作终究是不值得的，那么对那些可怜的低级工
+   程师来说也是很困难的，虽然实际的 **工作** 很容易删除，但你可能已经不可
+   挽回地失去了工程师的信任。记住：“不可撤销”是我们一开始就试图避免的，
+   而你的决定终究是一个重大的决定。
+
+令人欣慰的是，这两个原因都可以通过预先承认你没有任何线索，提前告诉人们你的
+决定完全是初步的，而且可能是错误的事情来有效地缓解。你应该始终保留改变主意
+的权利，并让人们 **意识** 到这一点。当你 **还没有** 做过真正愚蠢的事情的时
+候，承认自己是愚蠢的要容易得多。
+
+然后，当它真的被证明是愚蠢的时候，人们就转动他们的眼珠说“哎呀，下次不要了”。
+
+这种对不称职的先发制人的承认，也可能使真正做这项工作的人也会三思是否值得做。
+毕竟，如果他们不确定这是否是一个好主意，你肯定不应该通过向他们保证他们所做
+的工作将会进入（内核）鼓励他们。在他们开始一项巨大的努力之前，至少让他们三
+思而后行。
+
+记住：他们最好比你更了解细节，而且他们通常认为他们对每件事都有答案。作为一
+个管理者，你能做的最好的事情不是灌输自信，而是对他们所做的事情进行健康的批
+判性思考。
+
+顺便说一句，另一种避免做出决定的方法是看起来很可怜的抱怨 “我们不能两者兼
+得吗？” 相信我，它是有效的。如果不清楚哪种方法更好，他们最终会弄清楚的。
+最终的答案可能是两个团队都会因为这种情况而感到沮丧，以至于他们放弃了。
+
+这听起来像是一个失败，但这通常是一个迹象，表明两个项目都有问题，而参与其中
+的人不能做决定的原因是他们都是错误的。你最终会闻到玫瑰的味道，你避免了另一
+个你本可以搞砸的决定。
+
+2）人
+-----
+
+大多数人都是白痴，做一名管理者意味着你必须处理好这件事，也许更重要的是,
+**他们** 必须处理好你。
+
+事实证明，虽然很容易纠正技术错误，但不容易纠正人格障碍。你只能和他们的和
+你的（人格障碍）共处。
+
+但是，为了做好作为内核管理者的准备，最好记住不要烧掉任何桥梁，不要轰炸任何
+无辜的村民，也不要疏远太多的内核开发人员。事实证明，疏远人是相当容易的，而
+亲近一个疏远的人是很难的。因此，“疏远”立即属于“不可逆”的范畴，并根据
+:ref:`decisions` 成为绝不可以做的事情。
+
+这里只有几个简单的规则：
+
+ (1) 不要叫人笨蛋（至少不要在公共场合）
+ (2) 学习如何在忘记规则(1)时道歉
+
+问题在于 #1 很容易去做，因为你可以用数百万种不同的方式说“你是一个笨蛋” [#cnf2]_
+有时甚至没有意识到，而且几乎总是带着一种白热化的信念，认为你是对的。
+
+你越确信自己是对的（让我们面对现实吧，你可以把几乎所有人都称为坏人，而且你
+经常是对的），事后道歉就越难。
+
+要解决此问题，您实际上只有两个选项：
+
+ - 非常擅长道歉
+ - 把“爱”均匀地散开，没有人会真正感觉到自己被不公平地瞄准了。让它有足够的
+   创造性，他们甚至可能会觉得好笑。
+
+选择永远保持礼貌是不存在的。没有人会相信一个如此明显地隐藏了他们真实性格的人。
+
+.. [#cnf2] 保罗·西蒙演唱了“离开爱人的50种方法”，因为坦率地说，“告诉开发者
+   他们是D*CKHEAD" 的100万种方法都无法确认。但我确信他已经这么想了。
+
+3）人2 - 好人
+-------------
+
+虽然大多数人都是白痴，但不幸的是，据此推论你也是白痴，尽管我们都自我感觉良
+好，我们比普通人更好（让我们面对现实吧，没有人相信他们是普通人或低于普通人），
+我们也应该承认我们不是最锋利的刀，而且会有其他人比你更不像白痴。
+
+有些人对聪明人反应不好。其他人利用它们。
+
+作为内核维护人员，确保您在第二组中。接受他们，因为他们会让你的工作更容易。
+特别是，他们能够为你做决定，这就是游戏的全部内容。
+
+所以当你发现一个比你聪明的人时，就顺其自然吧。你的管理职责在很大程度上变成
+了“听起来像是个好主意——去尝试吧”，或者“听起来不错，但是XXX呢？”“。第二个版
+本尤其是一个很好的方法，要么学习一些关于“XXX”的新东西，要么通过指出一些聪明
+人没有想到的东西来显得更具管理性。无论哪种情况，你都会赢。
+
+要注意的一件事是认识到一个领域的伟大不一定会转化为其他领域。所以你可能会向
+特定的方向刺激人们，但让我们面对现实吧，他们可能擅长他们所做的事情，而且对
+其他事情都很差劲。好消息是，人们往往会自然而然地重拾他们擅长的东西，所以当
+你向某个方向刺激他们时，你并不是在做不可逆转的事情，只是不要用力推。
+
+4）责备
+-------
+
+事情会出问题的，人们希望去责备人。贴标签，你就是受责备的人。
+
+事实上，接受责备并不难，尤其是当人们意识到这不 **全是** 你的过错时。这让我
+们找到了承担责任的最佳方式：为别人承担这件事。你会感觉很好，他们会感觉很好，
+没有受到指责. 那谁，失去了他们的全部36GB色情收藏的人，因为你的无能将勉强承
+认，你至少没有试图逃避责任。
+
+然后让真正搞砸了的开发人员（如果你能找到他们）私下知道他们搞砸了。不仅是为
+了将来可以避免，而且为了让他们知道他们欠你一个人情。而且，也许更重要的是，
+他们也可能是能够解决问题的人。因为，让我们面对现实吧，肯定不是你。
+
+承担责任也是你首先成为管理者的原因。这是让人们信任你，让你获得潜在的荣耀的
+一部分，因为你就是那个会说“我搞砸了”的人。如果你已经遵循了以前的规则，你现
+在已经很擅长说了。
+
+5）应避免的事情
+---------------
+
+有一件事人们甚至比被称为“笨蛋”更讨厌，那就是在一个神圣的声音中被称为“笨蛋”。
+第一个你可以道歉，第二个你不会真正得到机会。即使你做得很好，他们也可能不再
+倾听。
+
+我们都认为自己比别人强，这意味着当别人装腔作势时，这会让我们很恼火。你也许
+在道德和智力上比你周围的每个人都优越，但不要试图太明显，除非你真的打算激怒
+某人 [#cnf3]_
+
+同样，不要对事情太客气或太微妙。礼貌很容易落得落花流水，把问题隐藏起来，
+正如他们所说，“在互联网上，没人能听到你的含蓄。”用一个钝器把这一点锤进去，
+因为你不能真的依靠别人来获得你的观点。
+
+一些幽默可以帮助缓和直率和道德化。过度到荒谬的地步，可以灌输一个观点，而不
+会让接受者感到痛苦，他们只是认为你是愚蠢的。因此，它可以帮助我们摆脱对批评
+的个人心理障碍。
+
+.. [#cnf3] 提示：与你的工作没有直接关系的网络新闻组是消除你对他人不满的好
+   方法。偶尔写些侮辱性的帖子，打个喷嚏，让你的情绪得到净化。别把牢骚带回家
+
+6）为什么是我？
+---------------
+
+既然你的主要责任似乎是为别人的错误承担责任，并且让别人痛苦地明白你是不称职
+的，那么显而易见的问题之一就变成了为什么首先要这样做。
+
+首先，虽然你可能会或可能不会听到十几岁女孩（或男孩，让我们不要在这里评判或
+性别歧视）敲你的更衣室门，你会得到一个巨大的个人成就感为“负责”。别介意你真
+的在领导别人，你要跟上别人，尽可能快地追赶他们。每个人都会认为你是负责人。
+
+如果你可以做到这个， 这是个伟大的工作！

+程序设计语言
+============
+
+内核是用C语言 [c-language]_ 编写的。更准确地说，内核通常是用 ``gcc`` [gcc]_
+在 ``-std=gnu89`` [gcc-c-dialect-options]_ 下编译的：ISO C90的 GNU 方言（
+包括一些C99特性）
+
+这种方言包含对语言 [gnu-extensions]_ 的许多扩展，当然，它们许多都在内核中使用。
+
+对于一些体系结构，有一些使用 ``clang`` [clang]_ 和 ``icc`` [icc]_ 编译内核
+的支持，尽管在编写此文档时还没有完成，仍需要第三方补丁。
+
+属性
+----
+
+在整个内核中使用的一个常见扩展是属性（attributes） [gcc-attribute-syntax]_
+属性允许将实现定义的语义引入语言实体（如变量、函数或类型），而无需对语言进行
+重大的语法更改（例如添加新关键字） [n2049]_
+
+在某些情况下，属性是可选的（即不支持这些属性的编译器仍然应该生成正确的代码，
+即使其速度较慢或执行的编译时检查/诊断次数不够）
+
+内核定义了伪关键字（例如， ``pure`` ），而不是直接使用GNU属性语法（例如,
+``__attribute__((__pure__))`` ），以检测可以使用哪些关键字和/或缩短代码, 具体

+Linux 内核驱动接口
+==================
+
+写作本文档的目的，是为了解释为什么Linux既没有二进制内核接口，也没有稳定
+的内核接口。这里所说的内核接口，是指内核里的接口，而不是内核和用户空间
+的接口。内核到用户空间的接口，是提供给应用程序使用的系统调用，系统调用
+在历史上几乎没有过变化，将来也不会有变化。我有一些老应用程序是在0.9版本
+或者更早版本的内核上编译的，在使用2.6版本内核的Linux发布上依然用得很好
+。用户和应用程序作者可以将这个接口看成是稳定的。
+
+
+执行纲要
+--------
+
+你也许以为自己想要稳定的内核接口，但是你不清楚你要的实际上不是它。你需
+要的其实是稳定的驱动程序，而你只有将驱动程序放到公版内核的源代码树里，
+才有可能达到这个目的。而且这样做还有很多其它好处，正是因为这些好处使得
+Linux能成为强壮，稳定，成熟的操作系统，这也是你最开始选择Linux的原因。
+
+
+入门
+-----
+
+只有那些写驱动程序的“怪人”才会担心内核接口的改变，对广大用户来说，既
+看不到内核接口，也不需要去关心它。
+
+首先，我不打算讨论关于任何非GPL许可的内核驱动的法律问题，这些非GPL许可
+的驱动程序包括不公开源代码，隐藏源代码，二进制或者是用源代码包装，或者
+是其它任何形式的不能以GPL许可公开源代码的驱动程序。如果有法律问题，请咨
+询律师，我只是一个程序员，所以我只打算探讨技术问题（不是小看法律问题，
+法律问题很实际，并且需要一直关注）。
+
+既然只谈技术问题，我们就有了下面两个主题：二进制内核接口和稳定的内核源
+代码接口。这两个问题是互相关联的，让我们先解决掉二进制接口的问题。
+
+
+二进制内核接口
+--------------
+假如我们有一个稳定的内核源代码接口，那么自然而然的，我们就拥有了稳定的
+二进制接口，是这样的吗？错。让我们看看关于Linux内核的几点事实：
+
+    - 取决于所用的C编译器的版本，不同的内核数据结构里的结构体的对齐方
+      式会有差别，代码中不同函数的表现形式也不一样（函数是不是被inline
+      编译取决于编译器行为）。不同的函数的表现形式并不重要，但是数据
+      结构内部的对齐方式很关键。
+
+    - 取决于内核的配置选项，不同的选项会让内核的很多东西发生改变：
+
+      - 同一个结构体可能包含不同的成员变量
+      - 有的函数可能根本不会被实现（比如编译的时候没有选择SMP支持
+        一些锁函数就会被定义成空函数）。
+      - 内核使用的内存会以不同的方式对齐，这取决于不同的内核配置选
+        项。
+
+    - Linux可以在很多的不同体系结构的处理器上运行。在某个体系结构上编
+      译好的二进制驱动程序，不可能在另外一个体系结构上正确的运行。
+
+对于一个特定的内核，满足这些条件并不难，使用同一个C编译器和同样的内核配
+置选项来编译驱动程序模块就可以了。这对于给一个特定Linux发布的特定版本提
+供驱动程序，是完全可以满足需求的。但是如果你要给不同发布的不同版本都发
+布一个驱动程序，就需要在每个发布上用不同的内核设置参数都编译一次内核，
+这简直跟噩梦一样。而且还要注意到，每个Linux发布还提供不同的Linux内核，
+这些内核都针对不同的硬件类型进行了优化（有很多种不同的处理器，还有不同
+的内核设置选项）。所以每发布一次驱动程序，都需要提供很多不同版本的内核
+模块。
+
+相信我，如果你真的要采取这种发布方式，一定会慢慢疯掉，我很久以前就有过
+深刻的教训...
+
+
+稳定的内核源代码接口
+--------------------
+
+如果有人不将他的内核驱动程序，放入公版内核的源代码树，而又想让驱动程序
+一直保持在最新的内核中可用，那么这个话题将会变得没完没了。
+内核开发是持续而且快节奏的，从来都不会慢下来。内核开发人员在当前接口中
+找到bug，或者找到更好的实现方式。一旦发现这些，他们就很快会去修改当前的
+接口。修改接口意味着，函数名可能会改变，结构体可能被扩充或者删减，函数
+的参数也可能发生改变。一旦接口被修改，内核中使用这些接口的地方需要同时
+修正，这样才能保证所有的东西继续工作。
+
+举一个例子，内核的USB驱动程序接口在USB子系统的整个生命周期中，至少经历
+了三次重写。这些重写解决以下问题：
+
+    - 把数据流从同步模式改成非同步模式，这个改动减少了一些驱动程序的
+      复杂度，提高了所有USB驱动程序的吞吐率，这样几乎所有的USB设备都
+      能以最大速率工作了。
+    - 修改了USB核心代码中为USB驱动分配数据包内存的方式，所有的驱动都
+      需要提供更多的参数给USB核心，以修正了很多已经被记录在案的死锁。
+
+这和一些封闭源代码的操作系统形成鲜明的对比，在那些操作系统上，不得不额
+外的维护旧的USB接口。这导致了一个可能性，新的开发者依然会不小心使用旧的
+接口，以不恰当的方式编写代码，进而影响到操作系统的稳定性。
+在上面的例子中，所有的开发者都同意这些重要的改动，在这样的情况下修改代
+价很低。如果Linux保持一个稳定的内核源代码接口，那么就得创建一个新的接口
+；旧的，有问题的接口必须一直维护，给Linux USB开发者带来额外的工作。既然
+所有的Linux USB驱动的作者都是利用自己的时间工作，那么要求他们去做毫无意
+义的免费额外工作，是不可能的。
+安全问题对Linux来说十分重要。一个安全问题被发现，就会在短时间内得到修
+正。在很多情况下，这将导致Linux内核中的一些接口被重写，以从根本上避免安
+全问题。一旦接口被重写，所有使用这些接口的驱动程序，必须同时得到修正，
+以确定安全问题已经得到修复并且不可能在未来还有同样的安全问题。如果内核
+内部接口不允许改变，那么就不可能修复这样的安全问题，也不可能确认这样的
+安全问题以后不会发生。
+开发者一直在清理内核接口。如果一个接口没有人在使用了，它就会被删除。这
+样可以确保内核尽可能的小，而且所有潜在的接口都会得到尽可能完整的测试
+（没有人使用的接口是不可能得到良好的测试的）。
+
+
+要做什么
+--------
+
+如果你写了一个Linux内核驱动，但是它还不在Linux源代码树里，作为一个开发
+者，你应该怎么做？为每个发布的每个版本提供一个二进制驱动，那简直是一个
+噩梦，要跟上永远处于变化之中的内核接口，也是一件辛苦活。
+很简单，让你的驱动进入内核源代码树（要记得我们在谈论的是以GPL许可发行
+的驱动，如果你的代码不符合GPL，那么祝你好运，你只能自己解决这个问题了，
+你这个吸血鬼<把Andrew和Linus对吸血鬼的定义链接到这里>）。当你的代码加入
+公版内核源代码树之后，如果一个内核接口改变，你的驱动会直接被修改接口的
+那个人修改。保证你的驱动永远都可以编译通过，并且一直工作，你几乎不需要
+做什么事情。
+
+把驱动放到内核源代码树里会有很多的好处：
+
+    - 驱动的质量会提升，而维护成本（对原始作者来说）会下降。
+    - 其他人会给驱动添加新特性。
+    - 其他人会找到驱动中的bug并修复。
+    - 其他人会在驱动中找到性能优化的机会。
+    - 当外部的接口的改变需要修改驱动程序的时候，其他人会修改驱动程序
+    - 不需要联系任何发行商，这个驱动会自动的随着所有的Linux发布一起发
+      布。
+
+和别的操作系统相比，Linux为更多不同的设备提供现成的驱动，而且能在更多不
+同体系结构的处理器上支持这些设备。这个经过考验的开发模式，必然是错不了
+的 :)

+所有你想知道的事情 - 关于linux稳定版发布
+========================================
+
+关于Linux 2.6稳定版发布，所有你想知道的事情。
+
+关于哪些类型的补丁可以被接收进入稳定版代码树，哪些不可以的规则：
+----------------------------------------------------------------
+
+  - 必须是显而易见的正确，并且经过测试的。
+  - 连同上下文，不能大于100行。
+  - 必须只修正一件事情。
+  - 必须修正了一个给大家带来麻烦的真正的bug（不是“这也许是一个问题...”
+    那样的东西）。
+  - 必须修正带来如下后果的问题：编译错误（对被标记为CONFIG_BROKEN的例外），
+    内核崩溃，挂起，数据损坏，真正的安全问题，或者一些类似“哦，这不
+    好”的问题。简短的说，就是一些致命的问题。
+  - 没有“理论上的竞争条件”，除非能给出竞争条件如何被利用的解释。
+  - 不能存在任何的“琐碎的”修正（拼写修正，去掉多余空格之类的）。
+  - 必须被相关子系统的维护者接受。
+  - 必须遵循Documentation/translations/zh_CN/process/submitting-patches.rst里的规则。
+
+向稳定版代码树提交补丁的过程：
+------------------------------
+
+  - 在确认了补丁符合以上的规则后，将补丁发送到stable@vger.kernel.org。
+  - 如果补丁被接受到队列里，发送者会收到一个ACK回复，如果没有被接受，收
+    到的是NAK回复。回复需要几天的时间，这取决于开发者的时间安排。
+  - 被接受的补丁会被加到稳定版本队列里，等待其他开发者的审查。
+  - 安全方面的补丁不要发到这个列表，应该发送到security@kernel.org。
+
+审查周期：
+----------
+
+  - 当稳定版的维护者决定开始一个审查周期，补丁将被发送到审查委员会，以
+    及被补丁影响的领域的维护者（除非提交者就是该领域的维护者）并且抄送
+    到linux-kernel邮件列表。
+  - 审查委员会有48小时的时间，用来决定给该补丁回复ACK还是NAK。
+  - 如果委员会中有成员拒绝这个补丁，或者linux-kernel列表上有人反对这个
+    补丁，并提出维护者和审查委员会之前没有意识到的问题，补丁会从队列中
+    丢弃。
+  - 在审查周期结束的时候，那些得到ACK回应的补丁将会被加入到最新的稳定版
+    发布中，一个新的稳定版发布就此产生。
+  - 安全性补丁将从内核安全小组那里直接接收到稳定版代码树中，而不是通过
+    通常的审查周期。请联系内核安全小组以获得关于这个过程的更多细节。
+
+审查委员会：
+------------
+  - 由一些自愿承担这项任务的内核开发者，和几个非志愿的组成。

+
+Linux内核补丁提交清单
+~~~~~~~~~~~~~~~~~~~~~
+
+如果开发人员希望看到他们的内核补丁提交更快地被接受，那么他们应该做一些基本
+的事情。
+
+这些都是在
+:ref:`Documentation/translations/zh_CN/process/submitting-patches.rst <cn_submittingpatches>`
+和其他有关提交Linux内核补丁的文档中提供的。
+
+1) 如果使用工具，则包括定义/声明该工具的文件。不要依赖于其他头文件拉入您使用
+   的头文件。
+
+2) 干净的编译：
+
+   a) 使用适用或修改的 ``CONFIG`` 选项 ``=y``、``=m`` 和 ``=n`` 。没有GCC
+      警告/错误，没有链接器警告/错误。
+
+   b) 通过allnoconfig、allmodconfig
+
+   c) 使用 ``O=builddir`` 时可以成功编译
+
+3) 通过使用本地交叉编译工具或其他一些构建场在多个CPU体系结构上构建。
+
+4) PPC64是一种很好的交叉编译检查体系结构，因为它倾向于对64位的数使用无符号
+   长整型。
+
+5) 如下所述 :ref:`Documentation/translations/zh_CN/process/coding-style.rst <cn_codingstyle>`.
+   检查您的补丁是否为常规样式。在提交（ ``scripts/check patch.pl`` ）之前，
+   使用补丁样式检查器检查是否有轻微的冲突。您应该能够处理您的补丁中存在的所有
+   违规行为。
+
+6) 任何新的或修改过的 ``CONFIG`` 选项都不会弄脏配置菜单，并默认为关闭，除非
+   它们符合 ``Documentation/kbuild/kconfig-language.txt`` 中记录的异常条件,
+   菜单属性：默认值.
+
+7) 所有新的 ``kconfig`` 选项都有帮助文本。
+
+8) 已仔细审查了相关的 ``Kconfig`` 组合。这很难用测试来纠正——脑力在这里是有
+   回报的。
+
+9) 用 sparse 检查干净。
+
+10) 使用 ``make checkstack`` 和 ``make namespacecheck`` 并修复他们发现的任何
+    问题。
+
+    .. note::
+
+        ``checkstack`` 并没有明确指出问题，但是任何一个在堆栈上使用超过512
+        字节的函数都可以进行更改。
+
+11) 包括 :ref:`kernel-doc <kernel_doc>` 内核文档以记录全局内核API。（静态函数
+    不需要，但也可以。）使用 ``make htmldocs`` 或 ``make pdfdocs`` 检查
+    :ref:`kernel-doc <kernel_doc>` 并修复任何问题。
+
+12) 通过以下选项同时启用的测试 ``CONFIG_PREEMPT``, ``CONFIG_DEBUG_PREEMPT``,
+    ``CONFIG_DEBUG_SLAB``, ``CONFIG_DEBUG_PAGEALLOC``, ``CONFIG_DEBUG_MUTEXES``,
+    ``CONFIG_DEBUG_SPINLOCK``, ``CONFIG_DEBUG_ATOMIC_SLEEP``,
+    ``CONFIG_PROVE_RCU`` and ``CONFIG_DEBUG_OBJECTS_RCU_HEAD``
+
+13) 已经过构建和运行时测试，包括有或没有 ``CONFIG_SMP``, ``CONFIG_PREEMPT``.
+
+14) 如果补丁程序影响IO/磁盘等：使用或不使用 ``CONFIG_LBDAF`` 进行测试。
+
+15) 所有代码路径都已在启用所有lockdep功能的情况下运行。
+
+16) 所有新的/proc条目都记录在 ``Documentation/``
+
+17) 所有新的内核引导参数都记录在
+    Documentation/admin-guide/kernel-parameters.rst 中。
+
+18) 所有新的模块参数都记录在 ``MODULE_PARM_DESC()``
+
+19) 所有新的用户空间接口都记录在 ``Documentation/ABI/`` 中。有关详细信息，
+    请参阅 ``Documentation/ABI/README`` 。更改用户空间接口的补丁应该抄送
+    linux-api@vger.kernel.org。
+
+20) 检查是否全部通过 ``make headers_check`` 。
+
+21) 已通过至少注入slab和page分配失败进行检查。请参阅 ``Documentation/fault-injection/``
+    如果新代码是实质性的，那么添加子系统特定的故障注入可能是合适的。
+
+22) 新添加的代码已经用 ``gcc -W`` 编译（使用 ``make EXTRA-CFLAGS=-W`` ）。这
+    将产生大量噪声，但对于查找诸如“警告：有符号和无符号之间的比较”之类的错误
+    很有用。
+
+23) 在它被合并到-mm补丁集中之后进行测试，以确保它仍然与所有其他排队的补丁以
+    及VM、VFS和其他子系统中的各种更改一起工作。
+
+24) 所有内存屏障例如 ``barrier()``, ``rmb()``, ``wmb()`` 都需要源代码中的注
+    释来解释它们正在执行的操作及其原因的逻辑。
+
+25) 如果补丁添加了任何ioctl，那么也要更新 ``Documentation/ioctl/ioctl-number.txt``
+
+26) 如果修改后的源代码依赖或使用与以下 ``Kconfig`` 符号相关的任何内核API或
+    功能，则在禁用相关 ``Kconfig`` 符号和/或 ``=m`` （如果该选项可用）的情况
+    下测试以下多个构建[并非所有这些都同时存在，只是它们的各种/随机组合]：
+
+    ``CONFIG_SMP``, ``CONFIG_SYSFS``, ``CONFIG_PROC_FS``, ``CONFIG_INPUT``, ``CONFIG_PCI``, ``CONFIG_BLOCK``, ``CONFIG_PM``, ``CONFIG_MAGIC_SYSRQ``,
+    ``CONFIG_NET``, ``CONFIG_INET=n`` (但是后者伴随 ``CONFIG_NET=y``).

+
+如何向 Linux 内核提交驱动程序
+=============================
+
+这篇文档将会解释如何向不同的内核源码树提交设备驱动程序。请注意，如果你感
+兴趣的是显卡驱动程序，你也许应该访问 XFree86 项目(http://www.xfree86.org/)
+和／或 X.org 项目 (http://x.org)。
+
+另请参阅 Documentation/Documentation/translations/zh_CN/process/submitting-patches.rst 文档。
+
+
+分配设备号
+----------
+
+块设备和字符设备的主设备号与从设备号是由 Linux 命名编号分配权威 LANANA（
+现在是 Torben Mathiasen）负责分配。申请的网址是 http://www.lanana.org/。
+即使不准备提交到主流内核的设备驱动也需要在这里分配设备号。有关详细信息，
+请参阅 Documentation/admin-guide/devices.rst。
+
+如果你使用的不是已经分配的设备号，那么当你提交设备驱动的时候，它将会被强
+制分配一个新的设备号，即便这个设备号和你之前发给客户的截然不同。
+
+设备驱动的提交对象
+------------------
+
+Linux 2.0:
+	此内核源码树不接受新的驱动程序。
+
+Linux 2.2:
+	此内核源码树不接受新的驱动程序。
+
+Linux 2.4:
+	如果所属的代码领域在内核的 MAINTAINERS 文件中列有一个总维护者，
+	那么请将驱动程序提交给他。如果此维护者没有回应或者你找不到恰当的
+	维护者，那么请联系 Willy Tarreau <w@1wt.eu>。
+
+Linux 2.6:
+	除了遵循和 2.4 版内核同样的规则外，你还需要在 linux-kernel 邮件
+	列表上跟踪最新的 API 变化。向 Linux 2.6 内核提交驱动的顶级联系人
+	是 Andrew Morton <akpm@linux-foundation.org>。
+
+决定设备驱动能否被接受的条件
+----------------------------
+
+许可：		代码必须使用 GNU 通用公开许可证 (GPL) 提交给 Linux，但是
+		我们并不要求 GPL 是唯一的许可。你或许会希望同时使用多种
+		许可证发布，如果希望驱动程序可以被其他开源社区（比如BSD）
+		使用。请参考 include/linux/module.h 文件中所列出的可被
+		接受共存的许可。
+
+版权：		版权所有者必须同意使用 GPL 许可。最好提交者和版权所有者
+		是相同个人或实体。否则，必需列出授权使用 GPL 的版权所有
+		人或实体，以备验证之需。
+
+接口：		如果你的驱动程序使用现成的接口并且和其他同类的驱动程序行
+		为相似，而不是去发明无谓的新接口，那么它将会更容易被接受。
+		如果你需要一个 Linux 和 NT 的通用驱动接口，那么请在用
+		户空间实现它。
+
+代码：		请使用 Documentation/process/coding-style.rst 中所描述的 Linux 代码风
+		格。如果你的某些代码段（例如那些与 Windows 驱动程序包共
+		享的代码段）需要使用其他格式，而你却只希望维护一份代码，
+		那么请将它们很好地区分出来，并且注明原因。
+
+可移植性：	请注意，指针并不永远是 32 位的，不是所有的计算机都使用小
+		尾模式 (little endian) 存储数据，不是所有的人都拥有浮点
+		单元，不要随便在你的驱动程序里嵌入 x86 汇编指令。只能在
+		x86 上运行的驱动程序一般是不受欢迎的。虽然你可能只有 x86
+		硬件，很难测试驱动程序在其他平台上是否可用，但是确保代码
+		可以被轻松地移植却是很简单的。
+
+清晰度：	做到所有人都能修补这个驱动程序将会很有好处，因为这样你将
+		会直接收到修复的补丁而不是 bug 报告。如果你提交一个试图
+		隐藏硬件工作机理的驱动程序，那么它将会被扔进废纸篓。
+
+电源管理：	因为 Linux 正在被很多移动设备和桌面系统使用，所以你的驱
+		动程序也很有可能被使用在这些设备上。它应该支持最基本的电
+		源管理，即在需要的情况下实现系统级休眠和唤醒要用到的
+		.suspend 和 .resume 函数。你应该检查你的驱动程序是否能正
+		确地处理休眠与唤醒，如果实在无法确认，请至少把 .suspend
+		函数定义成返回 -ENOSYS（功能未实现）错误。你还应该尝试确
+		保你的驱动在什么都不干的情况下将耗电降到最低。要获得驱动
+		程序测试的指导，请参阅
+		Documentation/power/drivers-testing.txt。有关驱动程序电
+		源管理问题相对全面的概述，请参阅
+		Documentation/driver-api/pm/devices.rst。
+
+管理：		如果一个驱动程序的作者还在进行有效的维护，那么通常除了那
+		些明显正确且不需要任何检查的补丁以外，其他所有的补丁都会
+		被转发给作者。如果你希望成为驱动程序的联系人和更新者，最
+		好在代码注释中写明并且在 MAINTAINERS 文件中加入这个驱动
+		程序的条目。
+
+不影响设备驱动能否被接受的条件
+------------------------------
+
+供应商：	由硬件供应商来维护驱动程序通常是一件好事。不过，如果源码
+		树里已经有其他人提供了可稳定工作的驱动程序，那么请不要期
+		望“我是供应商”会成为内核改用你的驱动程序的理由。理想的情
+		况是：供应商与现有驱动程序的作者合作，构建一个统一完美的
+		驱动程序。
+
+作者：		驱动程序是由大的 Linux 公司研发还是由你个人编写，并不影
+		响其是否能被内核接受。没有人对内核源码树享有特权。只要你
+		充分了解内核社区，你就会发现这一点。

+同样，:ref:`Documentation/translations/zh_CN/process/submit-checklist.rst <cn_submitchecklist>`
+给出在提交代码前需要检查的项目的列表。如果你在提交一个驱动程序，那么
+同时阅读一下:
+:ref:`Documentation/process/submitting-drivers.rst <submittingdrivers>`
+
+其中许多步骤描述了Git版本控制系统的默认行为；如果您使用Git来准备补丁，
+您将发现它为您完成的大部分机械工作，尽管您仍然需要准备和记录一组合理的
+补丁。一般来说，使用git将使您作为内核开发人员的生活更轻松。
+
+
+0) 获取当前源码树
+-----------------
+
+如果您没有一个可以使用当前内核源代码的存储库，请使用git获取一个。您将要
+从主线存储库开始，它可以通过以下方式获取::
+
+        git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+
+但是，请注意，您可能不希望直接针对主线树进行开发。大多数子系统维护人员运
+行自己的树，并希望看到针对这些树准备的补丁。请参见MAINTAINERS文件中子系
+统的 **T:** 项以查找该树，或者简单地询问维护者该树是否未在其中列出。
+
+仍然可以通过tarballs下载内核版本（如下一节所述），但这是进行内核开发的
+一种困难的方式。
+
+1) "diff -up"
+-------------
+
+使用 "diff -up" 或者 "diff -uprN" 来创建补丁。
+
+所有内核的改动，都是以补丁的形式呈现的，补丁由 diff(1) 生成。创建补丁的
+时候，要确认它是以 "unified diff" 格式创建的，这种格式由 diff(1) 的 '-u'
+参数生成。而且，请使用 '-p' 参数，那样会显示每个改动所在的C函数，使得
+产生的补丁容易读得多。补丁应该基于内核源代码树的根目录，而不是里边的任
+何子目录。
+
+为一个单独的文件创建补丁，一般来说这样做就够了::
+
+        SRCTREE=linux
+        MYFILE=drivers/net/mydriver.c
+
+        cd $SRCTREE
+        cp $MYFILE $MYFILE.orig
+        vi $MYFILE      # make your change
+        cd ..
+        diff -up $SRCTREE/$MYFILE{.orig,} > /tmp/patch
+
+为多个文件创建补丁，你可以解开一个没有修改过的内核源代码树，然后和你自
+己的代码树之间做 diff 。例如::
+
+        MYSRC=/devel/linux
+
+        tar xvfz linux-3.19.tar.gz
+        mv linux-3.19 linux-3.19-vanilla
+        diff -uprN -X linux-3.19-vanilla/Documentation/dontdiff \
+                linux-3.19-vanilla $MYSRC > /tmp/patch
+
+"dontdiff" 是内核在编译的时候产生的文件的列表，列表中的文件在 diff(1)
+产生的补丁里会被跳过。
+
+确定你的补丁里没有包含任何不属于这次补丁提交的额外文件。记得在用diff(1)
+生成补丁之后，审阅一次补丁，以确保准确。
+
+如果你的改动很散乱，你应该研究一下如何将补丁分割成独立的部分，将改动分
+割成一系列合乎逻辑的步骤。这样更容易让其他内核开发者审核，如果你想你的
+补丁被接受，这是很重要的。请参阅：
+:ref:`cn_split_changes`
+
+如果你用 ``git`` , ``git rebase -i`` 可以帮助你这一点。如果你不用 ``git``,
+``quilt`` <http://savannah.nongnu.org/projects/quilt> 另外一个流行的选择。
+
+.. _cn_describe_changes:
+
+2) 描述你的改动
+---------------
+
+描述你的问题。无论您的补丁是一行错误修复还是5000行新功能，都必须有一个潜在
+的问题激励您完成这项工作。让审稿人相信有一个问题值得解决，让他们读完第一段
+是有意义的。
+
+描述用户可见的影响。直接崩溃和锁定是相当有说服力的，但并不是所有的错误都那么
+明目张胆。即使在代码审查期间发现了这个问题，也要描述一下您认为它可能对用户产
+生的影响。请记住，大多数Linux安装运行的内核来自二级稳定树或特定于供应商/产品
+的树，只从上游精选特定的补丁，因此请包含任何可以帮助您将更改定位到下游的内容：
+触发的场景、DMESG的摘录、崩溃描述、性能回归、延迟尖峰、锁定等。
+
+量化优化和权衡。如果您声称在性能、内存消耗、堆栈占用空间或二进制大小方面有所
+改进，请包括支持它们的数字。但也要描述不明显的成本。优化通常不是免费的，而是
+在CPU、内存和可读性之间进行权衡；或者，探索性的工作，在不同的工作负载之间进
+行权衡。请描述优化的预期缺点，以便审阅者可以权衡成本和收益。
+
+一旦问题建立起来，就要详细地描述一下您实际在做什么。对于审阅者来说，用简单的
+英语描述代码的变化是很重要的，以验证代码的行为是否符合您的意愿。
+
+如果您将补丁描述写在一个表单中，这个表单可以很容易地作为“提交日志”放入Linux
+的源代码管理系统git中，那么维护人员将非常感谢您。见 :ref:`cn_explicit_in_reply_to`.
+
+每个补丁只解决一个问题。如果你的描述开始变长，这就表明你可能需要拆分你的补丁。
+请见 :ref:`cn_split_changes`
+
+提交或重新提交修补程序或修补程序系列时，请包括完整的修补程序说明和理由。不要
+只说这是补丁（系列）的第几版。不要期望子系统维护人员引用更早的补丁版本或引用
+URL来查找补丁描述并将其放入补丁中。也就是说，补丁（系列）及其描述应该是独立的。
+这对维护人员和审查人员都有好处。一些评审者可能甚至没有收到补丁的早期版本。
+
+描述你在命令语气中的变化，例如“make xyzzy do frotz”而不是“[这个补丁]make
+xyzzy do frotz”或“[我]changed xyzzy to do frotz”，就好像你在命令代码库改变
+它的行为一样。
+
+如果修补程序修复了一个记录的bug条目，请按编号和URL引用该bug条目。如果补丁来
+自邮件列表讨论，请给出邮件列表存档的URL；使用带有 ``Message-ID`` 的
+https://lkml.kernel.org/ 重定向，以确保链接不会过时。
+
+但是，在没有外部资源的情况下，尽量让你的解释可理解。除了提供邮件列表存档或
+bug的URL之外，还要总结需要提交补丁的相关讨论要点。
+
+如果您想要引用一个特定的提交，不要只引用提交的 SHA-1 ID。还请包括提交的一行
+摘要，以便于审阅者了解它是关于什么的。例如::
+
+        Commit e21d2170f36602ae2708 ("video: remove unnecessary
+        platform_set_drvdata()") removed the unnecessary
+        platform_set_drvdata(), but left the variable "dev" unused,
+        delete it.
+
+您还应该确保至少使用前12位 SHA-1 ID. 内核存储库包含*许多*对象，使与较短的ID
+发生冲突的可能性很大。记住，即使现在不会与您的六个字符ID发生冲突，这种情况
+可能五年后改变。
+
+如果修补程序修复了特定提交中的错误，例如，使用 ``git bisct`` ，请使用带有前
+12个字符SHA-1 ID 的"Fixes:"标记和单行摘要。为了简化不要将标记拆分为多个，
+行、标记不受分析脚本“75列换行”规则的限制。例如::
+
+        Fixes: 54a4f0239f2e ("KVM: MMU: make kvm_mmu_zap_page() return the number of pages it actually freed")
+
+下列 ``git config`` 设置可以添加让 ``git log``, ``git show`` 漂亮的显示格式::
+
+	[core]
+		abbrev = 12
+	[pretty]
+		fixes = Fixes: %h (\"%s\")
+
+.. _cn_split_changes:
+
+3) 拆分你的改动
+---------------
+
+将每个逻辑更改分隔成一个单独的补丁。
+
+例如，如果你的改动里同时有bug修正和性能优化，那么把这些改动拆分到两个或
+者更多的补丁文件中。如果你的改动包含对API的修改，并且修改了驱动程序来适
+应这些新的API，那么把这些修改分成两个补丁。
+
+另一方面，如果你将一个单独的改动做成多个补丁文件，那么将它们合并成一个
+单独的补丁文件。这样一个逻辑上单独的改动只被包含在一个补丁文件里。
+
+如果有一个补丁依赖另外一个补丁来完成它的改动，那没问题。简单的在你的补
+丁描述里指出“这个补丁依赖某补丁”就好了。
+
+在将您的更改划分为一系列补丁时，要特别注意确保内核在系列中的每个补丁之后
+都能正常构建和运行。使用 ``git bisect`` 来追踪问题的开发者可能会在任何时
+候分割你的补丁系列；如果你在中间引入错误，他们不会感谢你。
+
+如果你不能将补丁浓缩成更少的文件，那么每次大约发送出15个，然后等待审查
+和集成。
+
+4) 检查你的更改风格
+-------------------
+
+检查您的补丁是否存在基本样式冲突，详细信息可在
+:ref:`Documentation/translations/zh_CN/process/coding-style.rst <cn_codingstyle>`
+中找到。如果不这样做，只会浪费审稿人的时间，并且会导致你的补丁被拒绝，甚至
+可能没有被阅读。
+
+一个重要的例外是在将代码从一个文件移动到另一个文件时——在这种情况下，您不应
+该在移动代码的同一个补丁中修改移动的代码。这清楚地描述了移动代码和您的更改
+的行为。这大大有助于审查实际差异，并允许工具更好地跟踪代码本身的历史。
+
+在提交之前，使用补丁样式检查程序检查补丁（scripts/check patch.pl）。不过，
+请注意，样式检查程序应该被视为一个指南，而不是作为人类判断的替代品。如果您
+的代码看起来更好，但有违规行为，那么最好不要使用它。
+
+检查者报告三个级别：
+
+ - ERROR：很可能出错的事情
+ - WARNING：需要仔细审查的事项
+ - CHECK：需要思考的事情
+
+您应该能够判断您的补丁中存在的所有违规行为。
+
+5) 选择补丁收件人
+-----------------
+
+您应该总是在任何补丁上复制相应的子系统维护人员，以获得他们维护的代码；查看
+维护人员文件和源代码修订历史记录，以了解这些维护人员是谁。脚本
+scripts/get_Maintainer.pl在这个步骤中非常有用。如果您找不到正在工作的子系统
+的维护人员，那么Andrew Morton（akpm@linux-foundation.org）将充当最后的维护
+人员。
+
+您通常还应该选择至少一个邮件列表来接收补丁集的。linux-kernel@vger.kernel.org
+作为最后一个解决办法的列表，但是这个列表上的体积已经引起了许多开发人员的拒绝。
+在MAINTAINERS文件中查找子系统特定的列表；您的补丁可能会在那里得到更多的关注。
+不过，请不要发送垃圾邮件到无关的列表。
+
+许多与内核相关的列表托管在vger.kernel.org上；您可以在
+http://vger.kernel.org/vger-lists.html 上找到它们的列表。不过，也有与内核相关
+的列表托管在其他地方。
+
+不要一次发送超过15个补丁到vger邮件列表！！！！
+
+Linus Torvalds 是决定改动能否进入 Linux 内核的最终裁决者。他的 e-mail
+地址是 <torvalds@linux-foundation.org> 。他收到的 e-mail 很多，所以一般
+的说，最好别给他发 e-mail。
+
+如果您有修复可利用安全漏洞的补丁，请将该补丁发送到 security@kernel.org。对于
+严重的bug，可以考虑短期暂停以允许分销商向用户发布补丁；在这种情况下，显然不应
+将补丁发送到任何公共列表。
+
+修复已发布内核中严重错误的补丁程序应该指向稳定版维护人员，方法是放这样的一行::
+
+        Cc: stable@vger.kernel.org
+
+进入补丁的签准区（注意，不是电子邮件收件人）。除了这个文件之外，您还应该阅读
+:ref:`Documentation/process/stable-kernel-rules.rst <stable_kernel_rules>`
+
+但是，请注意，一些子系统维护人员希望得出他们自己的结论，即哪些补丁应该被放到
+稳定的树上。尤其是网络维护人员，不希望看到单个开发人员在补丁中添加像上面这样
+的行。
+
+如果更改影响到用户和内核接口，请向手册页维护人员（如维护人员文件中所列）发送
+手册页补丁，或至少发送更改通知，以便一些信息进入手册页。还应将用户空间API
+更改复制到 linux-api@vger.kernel.org。
+
+对于小的补丁，你也许会CC到搜集琐碎补丁的邮件列表(Trivial Patch Monkey)
+trivial@kernel.org，那里专门收集琐碎的补丁。下面这样的补丁会被看作“琐碎的”
+补丁：
+
+ - 文档的拼写修正。
+ - 修正会影响到 grep(1) 的拼写。
+ - 警告信息修正(频繁的打印无用的警告是不好的。)
+ - 编译错误修正（代码逻辑的确是对的，只是编译有问题。）
+ - 运行时修正（只要真的修正了错误。）
+ - 移除使用了被废弃的函数/宏的代码(例如 check_region。)
+ - 联系方式和文档修正。
+ - 用可移植的代码替换不可移植的代码（即使在体系结构相关的代码中，既然有
+ - 人拷贝，只要它是琐碎的）
+ - 任何文件的作者/维护者对该文件的改动（例如 patch monkey 在重传模式下）
+
+(译注，关于“琐碎补丁”的一些说明：因为原文的这一部分写得比较简单，所以不得不
+违例写一下译注。"trivial"这个英文单词的本意是“琐碎的，不重要的。”但是在这里
+有稍微有一些变化，例如对一些明显的NULL指针的修正，属于运行时修正，会被归类
+到琐碎补丁里。虽然NULL指针的修正很重要，但是这样的修正往往很小而且很容易得到
+检验，所以也被归入琐碎补丁。琐碎补丁更精确的归类应该是
+“simple, localized & easy to verify”，也就是说简单的，局部的和易于检验的。
+trivial@kernel.org邮件列表的目的是针对这样的补丁，为提交者提供一个中心，来
+降低提交的门槛。)
+
+6) 没有 MIME 编码，没有链接，没有压缩，没有附件，只有纯文本
+-----------------------------------------------------------
+
+Linus 和其他的内核开发者需要阅读和评论你提交的改动。对于内核开发者来说
+，可以“引用”你的改动很重要，使用一般的 e-mail 工具，他们就可以在你的
+代码的任何位置添加评论。
+
+因为这个原因，所有的提交的补丁都是 e-mail 中“内嵌”的。
+
+.. warning::
+   如果你使用剪切-粘贴你的补丁，小心你的编辑器的自动换行功能破坏你的补丁
+
+不要将补丁作为 MIME 编码的附件，不管是否压缩。很多流行的 e-mail 软件不
+是任何时候都将 MIME 编码的附件当作纯文本发送的，这会使得别人无法在你的
+代码中加评论。另外，MIME 编码的附件会让 Linus 多花一点时间来处理，这就
+降低了你的改动被接受的可能性。
+
+例外：如果你的邮递员弄坏了补丁，那么有人可能会要求你使用mime重新发送补丁
+
+请参阅 :ref:`Documentation/translations/zh_CN/process/email-clients.rst <cn_email_clients>`
+以获取有关配置电子邮件客户端以使其不受影响地发送修补程序的提示。
+
+7) e-mail 的大小
+----------------
+
+大的改动对邮件列表不合适，对某些维护者也不合适。如果你的补丁，在不压缩
+的情况下，超过了300kB，那么你最好将补丁放在一个能通过 internet 访问的服
+务器上，然后用指向你的补丁的 URL 替代。但是请注意，如果您的补丁超过了
+300kb，那么它几乎肯定需要被破坏。
+
+8）回复评审意见
+---------------
+
+你的补丁几乎肯定会得到评审者对补丁改进方法的评论。您必须对这些评论作出
+回应；让补丁被忽略的一个好办法就是忽略审阅者的意见。不会导致代码更改的
+意见或问题几乎肯定会带来注释或变更日志的改变，以便下一个评审者更好地了解
+正在发生的事情。
+
+一定要告诉审稿人你在做什么改变，并感谢他们的时间。代码审查是一个累人且
+耗时的过程，审查人员有时会变得暴躁。即使在这种情况下，也要礼貌地回应并
+解决他们指出的问题。
+
+9）不要泄气或不耐烦
+-------------------
+
+提交更改后，请耐心等待。审阅者是忙碌的人，可能无法立即访问您的修补程序。
+
+曾几何时，补丁曾在没有评论的情况下消失在空白中，但开发过程比现在更加顺利。
+您应该在一周左右的时间内收到评论；如果没有收到评论，请确保您已将补丁发送
+到正确的位置。在重新提交或联系审阅者之前至少等待一周-在诸如合并窗口之类的
+繁忙时间可能更长。
+
+10）主题中包含 PATCH
+--------------------
+
+由于到linus和linux内核的电子邮件流量很高，通常会在主题行前面加上[PATCH]
+前缀. 这使Linus和其他内核开发人员更容易将补丁与其他电子邮件讨论区分开。
+
+11）签署你的作品-开发者原始认证
+-------------------------------
+
+为了加强对谁做了何事的追踪，尤其是对那些透过好几层的维护者的补丁，我们
+建议在发送出去的补丁上加一个 “sign-off” 的过程。
+
+"sign-off" 是在补丁的注释的最后的简单的一行文字，认证你编写了它或者其他
+人有权力将它作为开放源代码的补丁传递。规则很简单：如果你能认证如下信息:
+
+开发者来源证书 1.1
+^^^^^^^^^^^^^^^^^^
+
+对于本项目的贡献，我认证如下信息：
+
+      （a）这些贡献是完全或者部分的由我创建，我有权利以文件中指出
+           的开放源代码许可证提交它；或者
+      （b）这些贡献基于以前的工作，据我所知，这些以前的工作受恰当的开放
+           源代码许可证保护，而且，根据许可证，我有权提交修改后的贡献，
+           无论是完全还是部分由我创造，这些贡献都使用同一个开放源代码许可证
+           （除非我被允许用其它的许可证），正如文件中指出的；或者
+      （c）这些贡献由认证（a），（b）或者（c）的人直接提供给我，而
+           且我没有修改它。
+      （d）我理解并同意这个项目和贡献是公开的，贡献的记录（包括我
+           一起提交的个人记录，包括 sign-off ）被永久维护并且可以和这个项目
+           或者开放源代码的许可证同步地再发行。
+
+那么加入这样一行::
+
+       Signed-off-by: Random J Developer <random@developer.example.org>
+
+使用你的真名（抱歉，不能使用假名或者匿名。）
+
+有人在最后加上标签。现在这些东西会被忽略，但是你可以这样做，来标记公司
+内部的过程，或者只是指出关于 sign-off 的一些特殊细节。
+
+如果您是子系统或分支维护人员，有时需要稍微修改收到的补丁，以便合并它们，
+因为树和提交者中的代码不完全相同。如果你严格遵守规则（c），你应该要求提交者
+重新发布，但这完全是在浪费时间和精力。规则（b）允许您调整代码，但是更改一个
+提交者的代码并让他认可您的错误是非常不礼貌的。要解决此问题，建议在最后一个
+由签名行和您的行之间添加一行，指示更改的性质。虽然这并不是强制性的，但似乎
+在描述前加上您的邮件和/或姓名（全部用方括号括起来），这足以让人注意到您对最
+后一分钟的更改负有责任。例如::
+
+	Signed-off-by: Random J Developer <random@developer.example.org>
+	[lucky@maintainer.example.org: struct foo moved from foo.c to foo.h]
+	Signed-off-by: Lucky K Maintainer <lucky@maintainer.example.org>
+
+如果您维护一个稳定的分支机构，同时希望对作者进行致谢、跟踪更改、合并修复并
+保护提交者不受投诉，那么这种做法尤其有用。请注意，在任何情况下都不能更改作者
+的ID（From 头），因为它是出现在更改日志中的标识。
+
+对回合（back-porters）的特别说明：在提交消息的顶部（主题行之后）插入一个补丁
+的起源指示似乎是一种常见且有用的实践，以便于跟踪。例如，下面是我们在3.x稳定
+版本中看到的内容::
+
+  Date:   Tue Oct 7 07:26:38 2014 -0400
+
+    libata: Un-break ATA blacklist
+
+    commit 1c40279960bcd7d52dbdf1d466b20d24b99176c8 upstream.
+
+还有， 这里是一个旧版内核中的一个回合补丁::
+
+    Date:   Tue May 13 22:12:27 2008 +0200
+
+        wireless, airo: waitbusy() won't delay
+
+        [backport of 2.6 commit b7acbdfbd1f277c1eb23f344f899cfa4cd0bf36a]
+
+12）何时使用Acked-by:，CC:，和Co-Developed by:
+----------------------------------------------
+
+Singed-off-by: 标记表示签名者参与了补丁的开发，或者他/她在补丁的传递路径中。
+
+如果一个人没有直接参与补丁的准备或处理，但希望表示并记录他们对补丁的批准，
+那么他们可以要求在补丁的变更日志中添加一个 Acked-by:
+
+Acked-by：通常由受影响代码的维护者使用，当该维护者既没有贡献也没有转发补丁时。
+
+Acked-by: 不像签字人那样正式。这是一个记录，确认人至少审查了补丁，并表示接受。
+因此，补丁合并有时会手动将Acker的“Yep，looks good to me”转换为 Acked-By：（但
+请注意，通常最好要求一个明确的Ack）。
+
+Acked-by：不一定表示对整个补丁的确认。例如，如果一个补丁影响多个子系统，并且
+有一个：来自一个子系统维护者，那么这通常表示只确认影响维护者代码的部分。这里
+应该仔细判断。如有疑问，应参考邮件列表档案中的原始讨论。
+
+如果某人有机会对补丁进行评论，但没有提供此类评论，您可以选择在补丁中添加 ``Cc:``
+这是唯一一个标签，它可以在没有被它命名的人显式操作的情况下添加，但它应该表明
+这个人是在补丁上抄送的。讨论中包含了潜在利益相关方。
+
+Co-developed-by: 声明补丁是由多个开发人员共同创建的；当几个人在一个补丁上工
+作时，它用于将属性赋予共同作者（除了 From: 所赋予的作者之外）。因为
+Co-developed-by: 表示作者身份，所以每个共同开发人：必须紧跟在相关合作作者的
+签名之后。标准的签核程序要求：标记的签核顺序应尽可能反映补丁的时间历史，而不
+管作者是通过 From ：还是由 Co-developed-by: 共同开发的。值得注意的是，最后一
+个签字人：必须始终是提交补丁的开发人员。
+
+注意，当作者也是电子邮件标题“发件人：”行中列出的人时，“From: ” 标记是可选的。
+
+作者提交的补丁程序示例::
+
+	<changelog>
+
+	Co-developed-by: First Co-Author <first@coauthor.example.org>
+	Signed-off-by: First Co-Author <first@coauthor.example.org>
+	Co-developed-by: Second Co-Author <second@coauthor.example.org>
+	Signed-off-by: Second Co-Author <second@coauthor.example.org>
+	Signed-off-by: From Author <from@author.example.org>
+
+合作开发者提交的补丁示例::
+
+	From: From Author <from@author.example.org>
+
+	<changelog>
+
+	Co-developed-by: Random Co-Author <random@coauthor.example.org>
+	Signed-off-by: Random Co-Author <random@coauthor.example.org>
+	Signed-off-by: From Author <from@author.example.org>
+	Co-developed-by: Submitting Co-Author <sub@coauthor.example.org>
+	Signed-off-by: Submitting Co-Author <sub@coauthor.example.org>
+
+
+13）使用报告人：、测试人：、审核人：、建议人：、修复人：
+--------------------------------------------------------
+
+Reported-by: 给那些发现错误并报告错误的人致谢，它希望激励他们在将来再次帮助
+我们。请注意，如果bug是以私有方式报告的，那么在使用Reported-by标记之前，请
+先请求权限。
+
+Tested-by: 标记表示补丁已由指定的人（在某些环境中）成功测试。这个标签通知
+维护人员已经执行了一些测试，为将来的补丁提供了一种定位测试人员的方法，并确
+保测试人员的信誉。
+
+Reviewed-by：相反，根据审查人的声明，表明该补丁已被审查并被认为是可接受的：
+
+
+审查人的监督声明
+^^^^^^^^^^^^^^^^
+
+通过提供我的 Reviewed-by，我声明：
+
+        (a) 我已经对这个补丁进行了一次技术审查，以评估它是否适合被包含到
+            主线内核中。
+
+        (b) 与补丁相关的任何问题、顾虑或问题都已反馈给提交者。我对提交者对
+            我的评论的回应感到满意。
+
+        (c) 虽然这一提交可能会改进一些东西，但我相信，此时，（1）对内核
+            进行了有价值的修改，（2）没有包含争论中涉及的已知问题。
+
+        (d) 虽然我已经审查了补丁并认为它是健全的，但我不会（除非另有明确
+            说明）作出任何保证或保证它将在任何给定情况下实现其规定的目的
+            或正常运行。
+
+Reviewed-by 是一种观点声明，即补丁是对内核的适当修改，没有任何遗留的严重技术
+问题。任何感兴趣的审阅者（完成工作的人）都可以为一个补丁提供一个 Review-by
+标签。此标签用于向审阅者提供致谢，并通知维护者已在修补程序上完成的审阅程度。
+Reviewed-by: 当由已知了解主题区域并执行彻底检查的审阅者提供时，通常会增加
+补丁进入内核的可能性。
+
+Suggested-by: 表示补丁的想法是由指定的人提出的，并确保将此想法归功于指定的
+人。请注意，未经许可，不得添加此标签，特别是如果该想法未在公共论坛上发布。
+这就是说，如果我们勤快地致谢我们的创意者，他们很有希望在未来得到鼓舞，再次
+帮助我们。
+
+Fixes: 指示补丁在以前的提交中修复了一个问题。它可以很容易地确定错误的来源，
+这有助于检查错误修复。这个标记还帮助稳定内核团队确定应该接收修复的稳定内核
+版本。这是指示补丁修复的错误的首选方法。请参阅 :ref:`cn_describe_changes`
+描述您的更改以了解更多详细信息。
+
+.. _cn_the_canonical_patch_format:
+
+12）标准补丁格式
+----------------
+
+本节描述如何格式化补丁本身。请注意，如果您的补丁存储在 ``Git`` 存储库中，则
+可以使用 ``git format-patch`` 进行正确的补丁格式设置。但是，这些工具无法创建
+必要的文本，因此请务必阅读下面的说明。
+
+标准的补丁，标题行是::
+
+    Subject: [PATCH 001/123] 子系统:一句话概述
+
+标准补丁的信体存在如下部分：
+
+  - 一个 "from" 行指出补丁作者。后跟空行（仅当发送修补程序的人不是作者时才需要）。
+
+  - 解释的正文，行以75列包装，这将被复制到永久变更日志来描述这个补丁。
+
+  - 一个空行
+
+  - 上面描述的“Signed-off-by” 行，也将出现在更改日志中。
+
+  - 只包含 ``---`` 的标记线。
+
+  - 任何其他不适合放在变更日志的注释。
+
+  - 实际补丁（ ``diff`` 输出）。
+
+标题行的格式，使得对标题行按字母序排序非常的容易 - 很多 e-mail 客户端都
+可以支持 - 因为序列号是用零填充的，所以按数字排序和按字母排序是一样的。
+
+e-mail 标题中的“子系统”标识哪个内核子系统将被打补丁。
+
+e-mail 标题中的“一句话概述”扼要的描述 e-mail 中的补丁。“一句话概述”
+不应该是一个文件名。对于一个补丁系列（“补丁系列”指一系列的多个相关补
+丁），不要对每个补丁都使用同样的“一句话概述”。
+
+记住 e-mail 的“一句话概述”会成为该补丁的全局唯一标识。它会蔓延到 git
+的改动记录里。然后“一句话概述”会被用在开发者的讨论里，用来指代这个补
+丁。用户将希望通过 google 来搜索"一句话概述"来找到那些讨论这个补丁的文
+章。当人们在两三个月后使用诸如 ``gitk`` 或 ``git log --oneline`` 之类
+的工具查看数千个补丁时，也会很快看到它。
+
+出于这些原因，概述必须不超过70-75个字符，并且必须描述补丁的更改以及为
+什么需要补丁。既要简洁又要描述性很有挑战性，但写得好的概述应该这样做。
+
+概述的前缀可以用方括号括起来：“Subject: [PATCH <tag>...] <概述>”。标记
+不被视为概述的一部分，而是描述应该如何处理补丁。如果补丁的多个版本已发
+送出来以响应评审（即“v1，v2，v3”）或“rfc”，以指示评审请求，那么通用标记
+可能包括版本描述符。如果一个补丁系列中有四个补丁，那么各个补丁可以这样
+编号：1/4、2/4、3/4、4/4。这可以确保开发人员了解补丁应用的顺序，并且他们
+已经查看或应用了补丁系列中的所有补丁。
+
+一些标题的例子::
+
+    Subject: [patch 2/5] ext2: improve scalability of bitmap searching
+    Subject: [PATCHv2 001/207] x86: fix eflags tracking
+
+"From" 行是信体里的最上面一行，具有如下格式：
+        From: Patch Author <author@example.com>
+
+"From" 行指明在永久改动日志里，谁会被确认为作者。如果没有 "From" 行，那
+么邮件头里的 "From: " 行会被用来决定改动日志中的作者。
+
+说明的主题将会被提交到永久的源代码改动日志里，因此对那些早已经不记得和
+这个补丁相关的讨论细节的有能力的读者来说，是有意义的。包括补丁程序定位
+错误的（内核日志消息、OOPS消息等）症状，对于搜索提交日志以寻找适用补丁的人
+尤其有用。如果一个补丁修复了一个编译失败，那么可能不需要包含所有编译失败；
+只要足够让搜索补丁的人能够找到它就行了。与概述一样，既要简洁又要描述性。
+
+"---" 标记行对于补丁处理工具要找到哪里是改动日志信息的结束，是不可缺少
+的。
+
+对于 "---" 标记之后的额外注解，一个好的用途就是用来写 diffstat，用来显
+示修改了什么文件和每个文件都增加和删除了多少行。diffstat 对于比较大的补
+丁特别有用。其余那些只是和时刻或者开发者相关的注解，不合适放到永久的改
+动日志里的，也应该放这里。
+使用 diffstat的选项 "-p 1 -w 70" 这样文件名就会从内核源代码树的目录开始
+，不会占用太宽的空间（很容易适合80列的宽度，也许会有一些缩进。）
+
+在后面的参考资料中能看到适当的补丁格式的更多细节。
+
+.. _cn_explicit_in_reply_to:
+
+15) 明确回复邮件头(In-Reply-To)
+-------------------------------
+
+手动添加回复补丁的的标题头(In-Reply_To:) 是有帮助的（例如，使用 ``git send-email`` ）
+将补丁与以前的相关讨论关联起来，例如，将bug修复程序链接到电子邮件和bug报告。
+但是，对于多补丁系列，最好避免在回复时使用链接到该系列的旧版本。这样，
+补丁的多个版本就不会成为电子邮件客户端中无法管理的引用序列。如果链接有用，
+可以使用 https://lkml.kernel.org/ 重定向器（例如，在封面电子邮件文本中）
+链接到补丁系列的早期版本。
+
+16) 发送git pull请求
+--------------------
+
+如果您有一系列补丁，那么让维护人员通过git pull操作将它们直接拉入子系统存储
+库可能是最方便的。但是，请注意，从开发人员那里获取补丁比从邮件列表中获取补
+丁需要更高的信任度。因此，许多子系统维护人员不愿意接受请求，特别是来自新的
+未知开发人员的请求。如果有疑问，您可以在封面邮件中使用pull 请求作为补丁系列
+正常发布的一个选项，让维护人员可以选择使用其中之一。
+
+pull 请求的主题行中应该有[Git Pull]。请求本身应该在一行中包含存储库名称和
+感兴趣的分支；它应该看起来像::
+
+  Please pull from
+
+      git://jdelvare.pck.nerim.net/jdelvare-2.6 i2c-for-linus
+
+  to get these changes:
+
+
+pull 请求还应该包含一条整体消息，说明请求中将包含什么，一个补丁本身的 ``Git shortlog``
+以及一个显示补丁系列整体效果的 ``diffstat`` 。当然，将所有这些信息收集在一起
+的最简单方法是让 ``git`` 使用 ``git request-pull`` 命令为您完成这些工作。
+
+一些维护人员（包括Linus）希望看到来自已签名提交的请求；这增加了他们对你的
+请求信心。特别是，在没有签名标签的情况下，Linus 不会从像 Github 这样的公共
+托管站点拉请求。
+
+创建此类签名的第一步是生成一个 GNRPG 密钥，并由一个或多个核心内核开发人员对
+其进行签名。这一步对新开发人员来说可能很困难，但没有办法绕过它。参加会议是
+找到可以签署您的密钥的开发人员的好方法。
+
+一旦您在Git 中准备了一个您希望有人拉的补丁系列，就用 ``git tag -s`` 创建一
+个签名标记。这将创建一个新标记，标识该系列中的最后一次提交，并包含用您的私
+钥创建的签名。您还可以将changelog样式的消息添加到标记中；这是一个描述拉请求
+整体效果的理想位置。
+
+如果维护人员将要从中提取的树不是您正在使用的存储库，请不要忘记将已签名的标记
+显式推送到公共树。
+
+生成拉请求时，请使用已签名的标记作为目标。这样的命令可以实现::
+
+  git request-pull master git://my.public.tree/linux.git my-signed-tag

+
+为什么不应该使用“volatile”类型
+==============================
+
+C程序员通常认为volatile表示某个变量可以在当前执行的线程之外被改变；因此，在内核
+中用到共享数据结构时，常常会有C程序员喜欢使用volatile这类变量。换句话说，他们经
+常会把volatile类型看成某种简易的原子变量，当然它们不是。在内核中使用volatile几
+乎总是错误的；本文档将解释为什么这样。
+
+理解volatile的关键是知道它的目的是用来消除优化，实际上很少有人真正需要这样的应
+用。在内核中，程序员必须防止意外的并发访问破坏共享的数据结构，这其实是一个完全
+不同的任务。用来防止意外并发访问的保护措施，可以更加高效的避免大多数优化相关的
+问题。
+
+像volatile一样，内核提供了很多原语来保证并发访问时的数据安全（自旋锁, 互斥量,内
+存屏障等等），同样可以防止意外的优化。如果可以正确使用这些内核原语，那么就没有
+必要再使用volatile。如果仍然必须使用volatile，那么几乎可以肯定在代码的某处有一
+个bug。在正确设计的内核代码中，volatile能带来的仅仅是使事情变慢。
+
+思考一下这段典型的内核代码::
+
+    spin_lock(&the_lock);
+    do_something_on(&shared_data);
+    do_something_else_with(&shared_data);
+    spin_unlock(&the_lock);
+
+如果所有的代码都遵循加锁规则，当持有the_lock的时候，不可能意外的改变shared_data的
+值。任何可能访问该数据的其他代码都会在这个锁上等待。自旋锁原语跟内存屏障一样—— 它
+们显式的用来书写成这样 —— 意味着数据访问不会跨越它们而被优化。所以本来编译器认为
+它知道在shared_data里面将有什么，但是因为spin_lock()调用跟内存屏障一样，会强制编
+译器忘记它所知道的一切。那么在访问这些数据时不会有优化的问题。
+
+如果shared_data被声名为volatile，锁操作将仍然是必须的。就算我们知道没有其他人正在
+使用它，编译器也将被阻止优化对临界区内shared_data的访问。在锁有效的同时，
+shared_data不是volatile的。在处理共享数据的时候，适当的锁操作可以不再需要
+volatile —— 并且是有潜在危害的。
+
+volatile的存储类型最初是为那些内存映射的I/O寄存器而定义。在内核里，寄存器访问也应
+该被锁保护，但是人们也不希望编译器“优化”临界区内的寄存器访问。内核里I/O的内存访问
+是通过访问函数完成的；不赞成通过指针对I/O内存的直接访问，并且不是在所有体系架构上
+都能工作。那些访问函数正是为了防止意外优化而写的，因此，再说一次，volatile类型不
+是必需的。
+
+另一种引起用户可能使用volatile的情况是当处理器正忙着等待一个变量的值。正确执行一
+个忙等待的方法是::
+
+    while (my_variable != what_i_want)
+        cpu_relax();
+
+cpu_relax()调用会降低CPU的能量消耗或者让位于超线程双处理器；它也作为内存屏障一样出
+现，所以，再一次，volatile不是必需的。当然，忙等待一开始就是一种反常规的做法。
+
+在内核中，一些稀少的情况下volatile仍然是有意义的：
+
+  - 在一些体系架构的系统上，允许直接的I/0内存访问，那么前面提到的访问函数可以使用
+    volatile。基本上，每一个访问函数调用它自己都是一个小的临界区域并且保证了按照
+    程序员期望的那样发生访问操作。
+
+  - 某些会改变内存的内联汇编代码虽然没有什么其他明显的附作用，但是有被GCC删除的可
+    能性。在汇编声明中加上volatile关键字可以防止这种删除操作。
+
+  - Jiffies变量是一种特殊情况，虽然每次引用它的时候都可以有不同的值，但读jiffies
+    变量时不需要任何特殊的加锁保护。所以jiffies变量可以使用volatile，但是不赞成
+    其他跟jiffies相同类型变量使用volatile。Jiffies被认为是一种“愚蠢的遗留物"
+    （Linus的话）因为解决这个问题比保持现状要麻烦的多。
+
+  - 由于某些I/0设备可能会修改连续一致的内存,所以有时,指向连续一致内存的数据结构
+    的指针需要正确的使用volatile。网络适配器使用的环状缓存区正是这类情形的一个例
+    子，其中适配器用改变指针来表示哪些描述符已经处理过了。
+
+对于大多代码，上述几种可以使用volatile的情况都不适用。所以，使用volatile是一种
+bug并且需要对这样的代码额外仔细检查。那些试图使用volatile的开发人员需要退一步想想
+他们真正想实现的是什么。
+
+非常欢迎删除volatile变量的补丁 － 只要证明这些补丁完整的考虑了并发问题。

-以下为正文
----------------------------------------------------------------------
-
-写作本文档的目的，是为了解释为什么Linux既没有二进制内核接口，也没有稳定
-的内核接口。这里所说的内核接口，是指内核里的接口，而不是内核和用户空间
-的接口。内核到用户空间的接口，是提供给应用程序使用的系统调用，系统调用
-在历史上几乎没有过变化，将来也不会有变化。我有一些老应用程序是在0.9版本
-或者更早版本的内核上编译的，在使用2.6版本内核的Linux发布上依然用得很好
-。用户和应用程序作者可以将这个接口看成是稳定的。
-
-
-执行纲要
---------
-
-你也许以为自己想要稳定的内核接口，但是你不清楚你要的实际上不是它。你需
-要的其实是稳定的驱动程序，而你只有将驱动程序放到公版内核的源代码树里，
-才有可能达到这个目的。而且这样做还有很多其它好处，正是因为这些好处使得
-Linux能成为强壮，稳定，成熟的操作系统，这也是你最开始选择Linux的原因。
-
-
-入门
------
-
-只有那些写驱动程序的“怪人”才会担心内核接口的改变，对广大用户来说，既
-看不到内核接口，也不需要去关心它。
-
-首先，我不打算讨论关于任何非GPL许可的内核驱动的法律问题，这些非GPL许可
-的驱动程序包括不公开源代码，隐藏源代码，二进制或者是用源代码包装，或者
-是其它任何形式的不能以GPL许可公开源代码的驱动程序。如果有法律问题，请咨
-询律师，我只是一个程序员，所以我只打算探讨技术问题（不是小看法律问题，
-法律问题很实际，并且需要一直关注）。
-
-既然只谈技术问题，我们就有了下面两个主题：二进制内核接口和稳定的内核源
-代码接口。这两个问题是互相关联的，让我们先解决掉二进制接口的问题。
-
-
-二进制内核接口
---------------
-假如我们有一个稳定的内核源代码接口，那么自然而然的，我们就拥有了稳定的
-二进制接口，是这样的吗？错。让我们看看关于Linux内核的几点事实：
-    - 取决于所用的C编译器的版本，不同的内核数据结构里的结构体的对齐方
-式会有差别，代码中不同函数的表现形式也不一样（函数是不是被inline编译取
-决于编译器行为）。不同的函数的表现形式并不重要，但是数据结构内部的对齐
-方式很关键。
-    - 取决于内核的配置选项，不同的选项会让内核的很多东西发生改变：
-      - 同一个结构体可能包含不同的成员变量
-      - 有的函数可能根本不会被实现（比如编译的时候没有选择SMP支持
-，一些锁函数就会被定义成空函数）。
-      - 内核使用的内存会以不同的方式对齐，这取决于不同的内核配置选
-项。
-    - Linux可以在很多的不同体系结构的处理器上运行。在某个体系结构上编
-译好的二进制驱动程序，不可能在另外一个体系结构上正确的运行。
-
-对于一个特定的内核，满足这些条件并不难，使用同一个C编译器和同样的内核配
-置选项来编译驱动程序模块就可以了。这对于给一个特定Linux发布的特定版本提
-供驱动程序，是完全可以满足需求的。但是如果你要给不同发布的不同版本都发
-布一个驱动程序，就需要在每个发布上用不同的内核设置参数都编译一次内核，
-这简直跟噩梦一样。而且还要注意到，每个Linux发布还提供不同的Linux内核，
-这些内核都针对不同的硬件类型进行了优化（有很多种不同的处理器，还有不同
-的内核设置选项）。所以每发布一次驱动程序，都需要提供很多不同版本的内核
-模块。
-
-相信我，如果你真的要采取这种发布方式，一定会慢慢疯掉，我很久以前就有过
-深刻的教训...
-
-
-稳定的内核源代码接口
---------------------
-
-如果有人不将他的内核驱动程序，放入公版内核的源代码树，而又想让驱动程序
-一直保持在最新的内核中可用，那么这个话题将会变得没完没了。
- 内核开发是持续而且快节奏的，从来都不会慢下来。内核开发人员在当前接口中
-找到bug，或者找到更好的实现方式。一旦发现这些，他们就很快会去修改当前的
-接口。修改接口意味着，函数名可能会改变，结构体可能被扩充或者删减，函数
-的参数也可能发生改变。一旦接口被修改，内核中使用这些接口的地方需要同时
-修正，这样才能保证所有的东西继续工作。
-
-举一个例子，内核的USB驱动程序接口在USB子系统的整个生命周期中，至少经历
-了三次重写。这些重写解决以下问题：
-    - 把数据流从同步模式改成非同步模式，这个改动减少了一些驱动程序的
-复杂度，提高了所有USB驱动程序的吞吐率，这样几乎所有的USB设备都能以最大
-速率工作了。
-    - 修改了USB核心代码中为USB驱动分配数据包内存的方式，所有的驱动都
-需要提供更多的参数给USB核心，以修正了很多已经被记录在案的死锁。
-
-这和一些封闭源代码的操作系统形成鲜明的对比，在那些操作系统上，不得不额
-外的维护旧的USB接口。这导致了一个可能性，新的开发者依然会不小心使用旧的
-接口，以不恰当的方式编写代码，进而影响到操作系统的稳定性。
- 在上面的例子中，所有的开发者都同意这些重要的改动，在这样的情况下修改代
-价很低。如果Linux保持一个稳定的内核源代码接口，那么就得创建一个新的接口
-；旧的，有问题的接口必须一直维护，给Linux USB开发者带来额外的工作。既然
-所有的Linux USB驱动的作者都是利用自己的时间工作，那么要求他们去做毫无意
-义的免费额外工作，是不可能的。
- 安全问题对Linux来说十分重要。一个安全问题被发现，就会在短时间内得到修
-正。在很多情况下，这将导致Linux内核中的一些接口被重写，以从根本上避免安
-全问题。一旦接口被重写，所有使用这些接口的驱动程序，必须同时得到修正，
-以确定安全问题已经得到修复并且不可能在未来还有同样的安全问题。如果内核
-内部接口不允许改变，那么就不可能修复这样的安全问题，也不可能确认这样的
-安全问题以后不会发生。
-开发者一直在清理内核接口。如果一个接口没有人在使用了，它就会被删除。这
-样可以确保内核尽可能的小，而且所有潜在的接口都会得到尽可能完整的测试
-（没有人使用的接口是不可能得到良好的测试的）。
-
-
-要做什么
--------
-
-如果你写了一个Linux内核驱动，但是它还不在Linux源代码树里，作为一个开发
-者，你应该怎么做？为每个发布的每个版本提供一个二进制驱动，那简直是一个
-噩梦，要跟上永远处于变化之中的内核接口，也是一件辛苦活。
-很简单，让你的驱动进入内核源代码树（要记得我们在谈论的是以GPL许可发行
-的驱动，如果你的代码不符合GPL，那么祝你好运，你只能自己解决这个问题了，
-你这个吸血鬼<把Andrew和Linus对吸血鬼的定义链接到这里>）。当你的代码加入
-公版内核源代码树之后，如果一个内核接口改变，你的驱动会直接被修改接口的
-那个人修改。保证你的驱动永远都可以编译通过，并且一直工作，你几乎不需要
-做什么事情。
-
-把驱动放到内核源代码树里会有很多的好处：
-    - 驱动的质量会提升，而维护成本（对原始作者来说）会下降。
-    - 其他人会给驱动添加新特性。
-    - 其他人会找到驱动中的bug并修复。
-    - 其他人会在驱动中找到性能优化的机会。
-    - 当外部的接口的改变需要修改驱动程序的时候，其他人会修改驱动程序
-。
-    - 不需要联系任何发行商，这个驱动会自动的随着所有的Linux发布一起发
-布。
-
-和别的操作系统相比，Linux为更多不同的设备提供现成的驱动，而且能在更多不
-同体系结构的处理器上支持这些设备。这个经过考验的开发模式，必然是错不了
-的 :)

-关于Linux 2.6稳定版发布，所有你想知道的事情。
-
-关于哪些类型的补丁可以被接收进入稳定版代码树，哪些不可以的规则：
-
-  - 必须是显而易见的正确，并且经过测试的。
-  - 连同上下文，不能大于100行。
-  - 必须只修正一件事情。
-  - 必须修正了一个给大家带来麻烦的真正的bug（不是“这也许是一个问题...”
-    那样的东西）。
-  - 必须修正带来如下后果的问题：编译错误（对被标记为CONFIG_BROKEN的例外），

-  - 被接受的补丁会被加到稳定版本队列里，等待其他开发者的审查。
-  - 安全方面的补丁不要发到这个列表，应该发送到security@kernel.org。
-
-审查周期：
-
-  - 当稳定版的维护者决定开始一个审查周期，补丁将被发送到审查委员会，以

-  - 审查委员会有48小时的时间，用来决定给该补丁回复ACK还是NAK。
-  - 如果委员会中有成员拒绝这个补丁，或者linux-kernel列表上有人反对这个
-    补丁，并提出维护者和审查委员会之前没有意识到的问题，补丁会从队列中
-    丢弃。
-  - 在审查周期结束的时候，那些得到ACK回应的补丁将会被加入到最新的稳定版
-    发布中，一个新的稳定版发布就此产生。
-  - 安全性补丁将从内核安全小组那里直接接收到稳定版代码树中，而不是通过
-    通常的审查周期。请联系内核安全小组以获得关于这个过程的更多细节。
-
-审查委员会：
-  - 由一些自愿承担这项任务的内核开发者，和几个非志愿的组成。

-如何向 Linux 内核提交驱动程序
------------------------------
-
-这篇文档将会解释如何向不同的内核源码树提交设备驱动程序。请注意，如果你感
-兴趣的是显卡驱动程序，你也许应该访问 XFree86 项目(http://www.xfree86.org/)
-和／或 X.org 项目 (http://x.org)。
-
-另请参阅 Documentation/process/submitting-patches.rst 文档。
-
-
-分配设备号
-----------
-
-块设备和字符设备的主设备号与从设备号是由 Linux 命名编号分配权威 LANANA（
-现在是 Torben Mathiasen）负责分配。申请的网址是 http://www.lanana.org/。
-即使不准备提交到主流内核的设备驱动也需要在这里分配设备号。有关详细信息，
-请参阅 Documentation/admin-guide/devices.rst。
-
-如果你使用的不是已经分配的设备号，那么当你提交设备驱动的时候，它将会被强
-制分配一个新的设备号，即便这个设备号和你之前发给客户的截然不同。
-
-设备驱动的提交对象
-------------------
-
-Linux 2.0:
-	此内核源码树不接受新的驱动程序。
-
-Linux 2.2:
-	此内核源码树不接受新的驱动程序。
-
-Linux 2.4:
-	如果所属的代码领域在内核的 MAINTAINERS 文件中列有一个总维护者，
-	那么请将驱动程序提交给他。如果此维护者没有回应或者你找不到恰当的
-	维护者，那么请联系 Willy Tarreau <w@1wt.eu>。
-
-Linux 2.6:
-	除了遵循和 2.4 版内核同样的规则外，你还需要在 linux-kernel 邮件
-	列表上跟踪最新的 API 变化。向 Linux 2.6 内核提交驱动的顶级联系人
-	是 Andrew Morton <akpm@linux-foundation.org>。
-
-决定设备驱动能否被接受的条件
-----------------------------
-
-许可：		代码必须使用 GNU 通用公开许可证 (GPL) 提交给 Linux，但是
-		我们并不要求 GPL 是唯一的许可。你或许会希望同时使用多种
-		许可证发布，如果希望驱动程序可以被其他开源社区（比如BSD）
-		使用。请参考 include/linux/module.h 文件中所列出的可被
-		接受共存的许可。
-
-版权：		版权所有者必须同意使用 GPL 许可。最好提交者和版权所有者
-		是相同个人或实体。否则，必需列出授权使用 GPL 的版权所有
-		人或实体，以备验证之需。
-
-接口：		如果你的驱动程序使用现成的接口并且和其他同类的驱动程序行
-		为相似，而不是去发明无谓的新接口，那么它将会更容易被接受。
-		如果你需要一个 Linux 和 NT 的通用驱动接口，那么请在用
-		户空间实现它。
-
-代码：		请使用 Documentation/process/coding-style.rst 中所描述的 Linux 代码风
-		格。如果你的某些代码段（例如那些与 Windows 驱动程序包共
-		享的代码段）需要使用其他格式，而你却只希望维护一份代码，
-		那么请将它们很好地区分出来，并且注明原因。
-
-可移植性：	请注意，指针并不永远是 32 位的，不是所有的计算机都使用小
-		尾模式 (little endian) 存储数据，不是所有的人都拥有浮点
-		单元，不要随便在你的驱动程序里嵌入 x86 汇编指令。只能在
-		x86 上运行的驱动程序一般是不受欢迎的。虽然你可能只有 x86
-		硬件，很难测试驱动程序在其他平台上是否可用，但是确保代码
-		可以被轻松地移植却是很简单的。
-
-清晰度：	做到所有人都能修补这个驱动程序将会很有好处，因为这样你将
-		会直接收到修复的补丁而不是 bug 报告。如果你提交一个试图
-		隐藏硬件工作机理的驱动程序，那么它将会被扔进废纸篓。
-
-电源管理：	因为 Linux 正在被很多移动设备和桌面系统使用，所以你的驱
-		动程序也很有可能被使用在这些设备上。它应该支持最基本的电
-		源管理，即在需要的情况下实现系统级休眠和唤醒要用到的
-		.suspend 和 .resume 函数。你应该检查你的驱动程序是否能正
-		确地处理休眠与唤醒，如果实在无法确认，请至少把 .suspend
-		函数定义成返回 -ENOSYS（功能未实现）错误。你还应该尝试确
-		保你的驱动在什么都不干的情况下将耗电降到最低。要获得驱动
-		程序测试的指导，请参阅
-		Documentation/power/drivers-testing.txt。有关驱动程序电
-		源管理问题相对全面的概述，请参阅
-		Documentation/driver-api/pm/devices.rst。
-
-管理：		如果一个驱动程序的作者还在进行有效的维护，那么通常除了那
-		些明显正确且不需要任何检查的补丁以外，其他所有的补丁都会
-		被转发给作者。如果你希望成为驱动程序的联系人和更新者，最
-		好在代码注释中写明并且在 MAINTAINERS 文件中加入这个驱动
-		程序的条目。
-
-不影响设备驱动能否被接受的条件
-------------------------------
-
-供应商：	由硬件供应商来维护驱动程序通常是一件好事。不过，如果源码
-		树里已经有其他人提供了可稳定工作的驱动程序，那么请不要期
-		望“我是供应商”会成为内核改用你的驱动程序的理由。理想的情
-		况是：供应商与现有驱动程序的作者合作，构建一个统一完美的
-		驱动程序。
-
-作者：		驱动程序是由大的 Linux 公司研发还是由你个人编写，并不影
-		响其是否能被内核接受。没有人对内核源码树享有特权。只要你
-		充分了解内核社区，你就会发现这一点。

-以下为正文
----------------------------------------------------------------------
-
-   如何让你的改动进入内核
-     或者
-  获得亲爱的 Linus Torvalds 的关注和处理
-----------------------------------
-
-对于想要将改动提交到 Linux 内核的个人或者公司来说，如果不熟悉“规矩”，
-提交的流程会让人畏惧。本文档收集了一系列建议，这些建议可以大大的提高你
-的改动被接受的机会。
-阅读 Documentation/process/submit-checklist.rst 来获得在提交代码前需要检查的项目的列
-表。如果你在提交一个驱动程序，那么同时阅读一下
-Documentation/process/submitting-drivers.rst 。
-
-
---------------------------
-第一节 - 创建并发送你的改动
---------------------------
-
-1) "diff -up"
------------
-
-使用 "diff -up" 或者 "diff -uprN" 来创建补丁。
-
-所有内核的改动，都是以补丁的形式呈现的，补丁由 diff(1) 生成。创建补丁的
-时候，要确认它是以 "unified diff" 格式创建的，这种格式由 diff(1) 的 '-u'
-参数生成。而且，请使用 '-p' 参数，那样会显示每个改动所在的C函数，使得
-产生的补丁容易读得多。补丁应该基于内核源代码树的根目录，而不是里边的任
-何子目录。
-为一个单独的文件创建补丁，一般来说这样做就够了：
-
-        SRCTREE= linux-2.6
-        MYFILE=  drivers/net/mydriver.c
-
-        cd $SRCTREE
-        cp $MYFILE $MYFILE.orig
-        vi $MYFILE      # make your change
-        cd ..
-        diff -up $SRCTREE/$MYFILE{.orig,} > /tmp/patch
-
-为多个文件创建补丁，你可以解开一个没有修改过的内核源代码树，然后和你自
-己的代码树之间做 diff 。例如：
-
-        MYSRC= /devel/linux-2.6
-
-        tar xvfz linux-2.6.12.tar.gz
-        mv linux-2.6.12 linux-2.6.12-vanilla
-        diff -uprN -X linux-2.6.12-vanilla/Documentation/dontdiff \
-                linux-2.6.12-vanilla $MYSRC > /tmp/patch
-
-"dontdiff" 是内核在编译的时候产生的文件的列表，列表中的文件在 diff(1)
-产生的补丁里会被跳过。"dontdiff" 文件被包含在2.6.12和之后版本的内核源代
-码树中。对于更早的内核版本，你可以从
-<http://www.xenotime.net/linux/doc/dontdiff> 获取它。
-确定你的补丁里没有包含任何不属于这次补丁提交的额外文件。记得在用diff(1)
-生成补丁之后，审阅一次补丁，以确保准确。
-如果你的改动很散乱，你应该研究一下如何将补丁分割成独立的部分，将改动分
-割成一系列合乎逻辑的步骤。这样更容易让其他内核开发者审核，如果你想你的
-补丁被接受，这是很重要的。下面这些脚本能够帮助你做这件事情：
-Quilt:
-http://savannah.nongnu.org/projects/quilt
-
-2)描述你的改动。
-描述你的改动包含的技术细节。
-
-要多具体就写多具体。最糟糕的描述可能是像下面这些语句：“更新了某驱动程
-序”，“修正了某驱动程序的bug”，或者“这个补丁包含了某子系统的修改，请
-使用。”
-
-如果你的描述开始变长，这表示你也许需要拆分你的补丁了，请看第3小节，
-继续。
-
-3)拆分你的改动
-
-将改动拆分，逻辑类似的放到同一个补丁文件里。
-
-例如，如果你的改动里同时有bug修正和性能优化，那么把这些改动拆分到两个或
-者更多的补丁文件中。如果你的改动包含对API的修改，并且修改了驱动程序来适
-应这些新的API，那么把这些修改分成两个补丁。
-
-另一方面，如果你将一个单独的改动做成多个补丁文件，那么将它们合并成一个
-单独的补丁文件。这样一个逻辑上单独的改动只被包含在一个补丁文件里。
-
-如果有一个补丁依赖另外一个补丁来完成它的改动，那没问题。简单的在你的补
-丁描述里指出“这个补丁依赖某补丁”就好了。
-
-如果你不能将补丁浓缩成更少的文件，那么每次大约发送出15个，然后等待审查
-和整合。
-
-4)选择 e-mail 的收件人
-
-看一遍 MAINTAINERS 文件和源代码，看看你所的改动所在的内核子系统有没有指
-定的维护者。如果有，给他们发e-mail。
-
-如果没有找到维护者，或者维护者没有反馈，将你的补丁发送到内核开发者主邮
-件列表 linux-kernel@vger.kernel.org。大部分的内核开发者都跟踪这个邮件列
-表，可以评价你的改动。
-
-每次不要发送超过15个补丁到 vger 邮件列表！！！
-
-Linus Torvalds 是决定改动能否进入 Linux 内核的最终裁决者。他的 e-mail
-地址是 <torvalds@linux-foundation.org> 。他收到的 e-mail 很多，所以一般
-的说，最好别给他发 e-mail。
-
-那些修正bug，“显而易见”的修改或者是类似的只需要很少讨论的补丁可以直接
-发送或者CC给Linus。那些需要讨论或者没有很清楚的好处的补丁，一般先发送到
-linux-kernel邮件列表。只有当补丁被讨论得差不多了，才提交给Linus。
-
-5)选择CC( e-mail 抄送)列表
-
-除非你有理由不这样做，否则CC linux-kernel@vger.kernel.org。
-
-除了 Linus 之外，其他内核开发者也需要注意到你的改动，这样他们才能评论你
-的改动并提供代码审查和建议。linux-kernel 是 Linux 内核开发者主邮件列表
-。其它的邮件列表为特定的子系统提供服务，比如 USB，framebuffer 设备，虚
-拟文件系统，SCSI 子系统，等等。查看 MAINTAINERS 文件来获得和你的改动有
-关的邮件列表。
-
-Majordomo lists of VGER.KERNEL.ORG at:
-        <http://vger.kernel.org/vger-lists.html>
-
-如果改动影响了用户空间和内核之间的接口，请给 MAN-PAGES 的维护者（列在
-MAINTAINERS 文件里的）发送一个手册页（man-pages）补丁，或者至少通知一下改
-变，让一些信息有途径进入手册页。
-
-即使在第四步的时候，维护者没有作出回应，也要确认在修改他们的代码的时候
-，一直将维护者拷贝到CC列表中。
-
-对于小的补丁，你也许会CC到 Adrian Bunk 管理的搜集琐碎补丁的邮件列表
-(Trivial Patch Monkey)trivial@kernel.org，那里专门收集琐碎的补丁。下面这样
-的补丁会被看作“琐碎的”补丁：
-  文档的拼写修正。
-  修正会影响到 grep(1) 的拼写。
-  警告信息修正(频繁的打印无用的警告是不好的。)
-  编译错误修正（代码逻辑的确是对的，只是编译有问题。）
-  运行时修正（只要真的修正了错误。）
-  移除使用了被废弃的函数/宏的代码(例如 check_region。)
-  联系方式和文档修正。
-  用可移植的代码替换不可移植的代码（即使在体系结构相关的代码中，既然有
-  人拷贝，只要它是琐碎的）
-  任何文件的作者/维护者对该文件的改动（例如 patch monkey 在重传模式下）
-
-EMAIL: trivial@kernel.org
-
-(译注，关于“琐碎补丁”的一些说明：因为原文的这一部分写得比较简单，所以不得不
-违例写一下译注。"trivial"这个英文单词的本意是“琐碎的，不重要的。”但是在这里
-有稍微有一些变化，例如对一些明显的NULL指针的修正，属于运行时修正，会被归类
-到琐碎补丁里。虽然NULL指针的修正很重要，但是这样的修正往往很小而且很容易得到
-检验，所以也被归入琐碎补丁。琐碎补丁更精确的归类应该是
-“simple, localized & easy to verify”，也就是说简单的，局部的和易于检验的。
-trivial@kernel.org邮件列表的目的是针对这样的补丁，为提交者提供一个中心，来
-降低提交的门槛。)
-
-6)没有 MIME 编码，没有链接，没有压缩，没有附件，只有纯文本。
-
-Linus 和其他的内核开发者需要阅读和评论你提交的改动。对于内核开发者来说
-，可以“引用”你的改动很重要，使用一般的 e-mail 工具，他们就可以在你的
-代码的任何位置添加评论。
-
-因为这个原因，所有的提交的补丁都是 e-mail 中“内嵌”的。
-警告：如果你使用剪切-粘贴你的补丁，小心你的编辑器的自动换行功能破坏你的
-补丁。
-
-不要将补丁作为 MIME 编码的附件，不管是否压缩。很多流行的 e-mail 软件不
-是任何时候都将 MIME 编码的附件当作纯文本发送的，这会使得别人无法在你的
-代码中加评论。另外，MIME 编码的附件会让 Linus 多花一点时间来处理，这就
-降低了你的改动被接受的可能性。
-
-警告：一些邮件软件，比如 Mozilla 会将你的信息以如下格式发送：
----- 邮件头 ----
-Content-Type: text/plain; charset=us-ascii; format=flowed
----- 邮件头 ----
-问题在于 “format=flowed” 会让接收端的某些邮件软件将邮件中的制表符替换
-成空格以及做一些类似的替换。这样，你发送的时候看起来没问题的补丁就被破
-坏了。
-
-要修正这个问题，只需要将你的 mozilla 的 defaults/pref/mailnews.js 文件
-里的
-pref("mailnews.send_plaintext_flowed", false); // RFC 2646=======
-修改成
-pref("mailnews.display.disable_format_flowed_support", true);
-就可以了。
-
-7) e-mail 的大小
-
-给 Linus 发送补丁的时候，永远按照第6小节说的做。
-
-大的改动对邮件列表不合适，对某些维护者也不合适。如果你的补丁，在不压缩
-的情况下，超过了40kB，那么你最好将补丁放在一个能通过 internet 访问的服
-务器上，然后用指向你的补丁的 URL 替代。
-
-8) 指出你的内核版本
-
-在标题和在补丁的描述中，指出补丁对应的内核的版本，是很重要的。
-
-如果补丁不能干净的在最新版本的内核上打上，Linus 是不会接受它的。
-
-9) 不要气馁，继续提交。
-
-当你提交了改动以后，耐心地等待。如果 Linus 喜欢你的改动并且同意它，那么
-它将在下一个内核发布版本中出现。
-
-然而，如果你的改动没有出现在下一个版本的内核中，可能有若干原因。减少那
-些原因，修正错误，重新提交更新后的改动，是你自己的工作。
-
-Linus不给出任何评论就“丢弃”你的补丁是常见的事情。在系统中这样的事情很
-平常。如果他没有接受你的补丁，也许是由于以下原因：
-* 你的补丁不能在最新版本的内核上干净的打上。
-* 你的补丁在 linux-kernel 邮件列表中没有得到充分的讨论。
-* 风格问题（参照第2小节）
-* 邮件格式问题（重读本节）
-* 你的改动有技术问题。
-* 他收到了成吨的 e-mail，而你的在混乱中丢失了。
-* 你让人为难。
-
-有疑问的时候，在 linux-kernel 邮件列表上请求评论。
-
-10) 在标题上加上 PATCH 的字样
-
-Linus 和 linux-kernel 邮件列表的 e-mail 流量都很高，一个通常的约定是标
-题行以 [PATCH] 开头。这样可以让 Linus 和其他内核开发人员可以从 e-mail
-的讨论中很轻易的将补丁分辨出来。
-
-11）为你的工作签名
-
-为了加强对谁做了何事的追踪，尤其是对那些透过好几层的维护者的补丁，我们
-建议在发送出去的补丁上加一个 “sign-off” 的过程。
-
-"sign-off" 是在补丁的注释的最后的简单的一行文字，认证你编写了它或者其他
-人有权力将它作为开放源代码的补丁传递。规则很简单：如果你能认证如下信息
-：
-      开发者来源证书 1.1
-      对于本项目的贡献，我认证如下信息：
-      （a）这些贡献是完全或者部分的由我创建，我有权利以文件中指出
-       的开放源代码许可证提交它；或者
-      （b）这些贡献基于以前的工作，据我所知，这些以前的工作受恰当的开放
-       源代码许可证保护，而且，根据许可证，我有权提交修改后的贡献，
-       无论是完全还是部分由我创造，这些贡献都使用同一个开放源代码许可证
-       （除非我被允许用其它的许可证），正如文件中指出的；或者
-      （c）这些贡献由认证（a），（b）或者（c）的人直接提供给我，而
-       且我没有修改它。
-      （d）我理解并同意这个项目和贡献是公开的，贡献的记录（包括我
-       一起提交的个人记录，包括 sign-off ）被永久维护并且可以和这个项目
-       或者开放源代码的许可证同步地再发行。
-       那么加入这样一行：
-       Signed-off-by: Random J Developer <random@developer.example.org>
-
-使用你的真名（抱歉，不能使用假名或者匿名。）
-
-有人在最后加上标签。现在这些东西会被忽略，但是你可以这样做，来标记公司
-内部的过程，或者只是指出关于 sign-off 的一些特殊细节。
-
-12）标准补丁格式
-
-标准的补丁，标题行是：
-    Subject: [PATCH 001/123] 子系统:一句话概述
-
-标准补丁的信体存在如下部分：
-
-  - 一个 "from" 行指出补丁作者。
-
-  - 一个空行
-
-  - 说明的主体，这些说明文字会被拷贝到描述该补丁的永久改动记录里。
-
-  - 一个由"---"构成的标记行
-
-  - 不合适放到改动记录里的额外的注解。
-
-  - 补丁本身（diff 输出）
-
-标题行的格式，使得对标题行按字母序排序非常的容易 - 很多 e-mail 客户端都
-可以支持 - 因为序列号是用零填充的，所以按数字排序和按字母排序是一样的。
-
-e-mail 标题中的“子系统”标识哪个内核子系统将被打补丁。
-
-e-mail 标题中的“一句话概述”扼要的描述 e-mail 中的补丁。“一句话概述”
-不应该是一个文件名。对于一个补丁系列（“补丁系列”指一系列的多个相关补
-丁），不要对每个补丁都使用同样的“一句话概述”。
-
-记住 e-mail 的“一句话概述”会成为该补丁的全局唯一标识。它会蔓延到 git
-的改动记录里。然后“一句话概述”会被用在开发者的讨论里，用来指代这个补
-丁。用户将希望通过 google 来搜索"一句话概述"来找到那些讨论这个补丁的文
-章。
-
-一些标题的例子：
-
-    Subject: [patch 2/5] ext2: improve scalability of bitmap searching
-    Subject: [PATCHv2 001/207] x86: fix eflags tracking
-
-"from" 行是信体里的最上面一行，具有如下格式：
-        From: Original Author <author@example.com>
-
-"from" 行指明在永久改动日志里，谁会被确认为作者。如果没有 "from" 行，那
-么邮件头里的 "From: " 行会被用来决定改动日志中的作者。
-
-说明的主题将会被提交到永久的源代码改动日志里，因此对那些早已经不记得和
-这个补丁相关的讨论细节的有能力的读者来说，是有意义的。
-
-"---" 标记行对于补丁处理工具要找到哪里是改动日志信息的结束，是不可缺少
-的。
-
-对于 "---" 标记之后的额外注解，一个好的用途就是用来写 diffstat，用来显
-示修改了什么文件和每个文件都增加和删除了多少行。diffstat 对于比较大的补
-丁特别有用。其余那些只是和时刻或者开发者相关的注解，不合适放到永久的改

-使用 diffstat的选项 "-p 1 -w 70" 这样文件名就会从内核源代码树的目录开始

-第二节 提示，建议和诀窍
--------------------------------
-
-本节包含很多和提交到内核的代码有关的通常的"规则"。事情永远有例外...但是
-你必须真的有好的理由这样做。你可以把本节叫做Linus的计算机科学入门课。
-
-1) 读 Document/process/coding-style.rst
-
-Nuff 说过，如果你的代码和这个偏离太多，那么它有可能会被拒绝，没有更多的
-审查，没有更多的评价。
-
-2) #ifdef 是丑陋的
-混杂了 ifdef 的代码难以阅读和维护。别这样做。作为替代，将你的 ifdef 放
-在头文件里，有条件地定义 "static inline" 函数，或者宏，在代码里用这些东
-西。让编译器把那些"空操作"优化掉。
-
-一个简单的例子，不好的代码：
-
-    dev = alloc_etherdev (sizeof(struct funky_private));
-    if (!dev)
-        return -ENODEV;
-    #ifdef CONFIG_NET_FUNKINESS
-    init_funky_net(dev);
-    #endif
-
-清理后的例子:
-
-(头文件里)
-    #ifndef CONFIG_NET_FUNKINESS
-    static inline void init_funky_net (struct net_device *d) {}
-    #endif
-
-(代码文件里)
-    dev = alloc_etherdev (sizeof(struct funky_private));
-    if (!dev)
-        return -ENODEV;
-    init_funky_net(dev);
-
-3) 'static inline' 比宏好
-
-Static inline 函数相比宏来说，是好得多的选择。Static inline 函数提供了
-类型安全，没有长度限制，没有格式限制，在 gcc 下开销和宏一样小。
-
-宏只在 static inline 函数不是最优的时候[在 fast paths 里有很少的独立的
-案例]，或者不可能用 static inline 函数的时候[例如字符串分配]。
-应该用 'static inline' 而不是 'static __inline__', 'extern inline' 和
-'extern __inline__' 。
-
-4) 不要过度设计
-
-不要试图预计模糊的未来事情，这些事情也许有用也许没有用："让事情尽可能的
-简单，而不是更简单"。

----------------------------------------------------------------------
-
-为什么不应该使用“volatile”类型
-------------------------------
-
-C程序员通常认为volatile表示某个变量可以在当前执行的线程之外被改变；因此，在内核
-中用到共享数据结构时，常常会有C程序员喜欢使用volatile这类变量。换句话说，他们经
-常会把volatile类型看成某种简易的原子变量，当然它们不是。在内核中使用volatile几
-乎总是错误的；本文档将解释为什么这样。
-
-理解volatile的关键是知道它的目的是用来消除优化，实际上很少有人真正需要这样的应
-用。在内核中，程序员必须防止意外的并发访问破坏共享的数据结构，这其实是一个完全
-不同的任务。用来防止意外并发访问的保护措施，可以更加高效的避免大多数优化相关的
-问题。
-
-像volatile一样，内核提供了很多原语来保证并发访问时的数据安全（自旋锁, 互斥量,内
-存屏障等等），同样可以防止意外的优化。如果可以正确使用这些内核原语，那么就没有
-必要再使用volatile。如果仍然必须使用volatile，那么几乎可以肯定在代码的某处有一
-个bug。在正确设计的内核代码中，volatile能带来的仅仅是使事情变慢。
-
-思考一下这段典型的内核代码：
-
-    spin_lock(&the_lock);
-    do_something_on(&shared_data);
-    do_something_else_with(&shared_data);
-    spin_unlock(&the_lock);
-
-如果所有的代码都遵循加锁规则，当持有the_lock的时候，不可能意外的改变shared_data的
-值。任何可能访问该数据的其他代码都会在这个锁上等待。自旋锁原语跟内存屏障一样—— 它
-们显式的用来书写成这样 —— 意味着数据访问不会跨越它们而被优化。所以本来编译器认为
-它知道在shared_data里面将有什么，但是因为spin_lock()调用跟内存屏障一样，会强制编
-译器忘记它所知道的一切。那么在访问这些数据时不会有优化的问题。
-
-如果shared_data被声名为volatile，锁操作将仍然是必须的。就算我们知道没有其他人正在
-使用它，编译器也将被阻止优化对临界区内shared_data的访问。在锁有效的同时，
-shared_data不是volatile的。在处理共享数据的时候，适当的锁操作可以不再需要
-volatile —— 并且是有潜在危害的。
-
-volatile的存储类型最初是为那些内存映射的I/O寄存器而定义。在内核里，寄存器访问也应
-该被锁保护，但是人们也不希望编译器“优化”临界区内的寄存器访问。内核里I/O的内存访问
-是通过访问函数完成的；不赞成通过指针对I/O内存的直接访问，并且不是在所有体系架构上
-都能工作。那些访问函数正是为了防止意外优化而写的，因此，再说一次，volatile类型不
-是必需的。
-
-另一种引起用户可能使用volatile的情况是当处理器正忙着等待一个变量的值。正确执行一
-个忙等待的方法是：
-
-    while (my_variable != what_i_want)
-        cpu_relax();
-
-cpu_relax()调用会降低CPU的能量消耗或者让位于超线程双处理器；它也作为内存屏障一样出
-现，所以，再一次，volatile不是必需的。当然，忙等待一开始就是一种反常规的做法。
-
-在内核中，一些稀少的情况下volatile仍然是有意义的：
-
-  - 在一些体系架构的系统上，允许直接的I/0内存访问，那么前面提到的访问函数可以使用
-    volatile。基本上，每一个访问函数调用它自己都是一个小的临界区域并且保证了按照
-    程序员期望的那样发生访问操作。
-
-  - 某些会改变内存的内联汇编代码虽然没有什么其他明显的附作用，但是有被GCC删除的可
-    能性。在汇编声明中加上volatile关键字可以防止这种删除操作。
-
-  - Jiffies变量是一种特殊情况，虽然每次引用它的时候都可以有不同的值，但读jiffies
-    变量时不需要任何特殊的加锁保护。所以jiffies变量可以使用volatile，但是不赞成
-    其他跟jiffies相同类型变量使用volatile。Jiffies被认为是一种“愚蠢的遗留物"
-    （Linus的话）因为解决这个问题比保持现状要麻烦的多。
-
-  - 由于某些I/0设备可能会修改连续一致的内存,所以有时,指向连续一致内存的数据结构
-    的指针需要正确的使用volatile。网络适配器使用的环状缓存区正是这类情形的一个例
-    子，其中适配器用改变指针来表示哪些描述符已经处理过了。
-
-对于大多代码，上述几种可以使用volatile的情况都不适用。所以，使用volatile是一种
-bug并且需要对这样的代码额外仔细检查。那些试图使用volatile的开发人员需要退一步想想
-他们真正想实现的是什么。
-
-非常欢迎删除volatile变量的补丁 － 只要证明这些补丁完整的考虑了并发问题。

 Interface authorization
 -----------------------
+
 There is a similar approach to allow or deny specific USB interfaces.
 That allows to block only a subset of an USB device.
 
-Authorize an interface:
-$ echo 1 > /sys/bus/usb/devices/INTERFACE/authorized

 The default value for new interfaces

 Configuration with configfs
+===========================
 
-	Instead of adding fake platform devices and drivers in order to pass

-	configfs the hidg_func_descriptor.report_desc is passed to the kernel
-	by writing the appropriate stream of bytes to a configfs attribute.

 replace it with a fresh one. In my case, what happened is I lost two 16kb

-
-
-REQUIREMENTS
-
-A host with a USB port.  Ideally, either a UHCI (Intel) or OHCI
-(Compaq and others) hardware port should work.
-
-A Linux development kernel (2.3.x) with USB support enabled or a
-backported version to linux-2.2.x.  See http://www.linux-usb.org for
-more information on accomplishing this.
-
-A Linux kernel with RIO 500 support enabled.
-
-'lspci' which is only needed to determine the type of USB hardware
-available in your machine.
-
-CONFIGURATION
-
-Using `lspci -v`, determine the type of USB hardware available.
+Additional Information and userspace tools
 
-  If you see something like:
+	http://rio500.sourceforge.net/
 
-    USB Controller: ......
-    Flags: .....
-    I/O ports at ....
 
-  Then you have a UHCI based controller.
+Requirements
+============
 
-  If you see something like:
+A host with a USB port running a Linux kernel with RIO 500 support enabled.
 
-     USB Controller: .....
-     Flags: ....
-     Memory at .....
+The driver is a module called rio500, which should be automatically loaded
+as you plug in your device. If that fails you can manually load it with
 
-  Then you have a OHCI based controller.
+  modprobe rio500
 
-Using `make menuconfig` or your preferred method for configuring the
-kernel, select 'Support for USB', 'OHCI/UHCI' depending on your
-hardware (determined from the steps above), 'USB Diamond Rio500 support', and
-'Preliminary USB device filesystem'.  Compile and install the modules
-(you may need to execute `depmod -a` to update the module
-dependencies).
+Udev should automatically create a device node as soon as plug in your device.
+If that fails, you can manually add a device for the USB rio500::
 
-Add a device for the USB rio500:
-  `mknod /dev/usb/rio500 c 180 64`
+  mknod /dev/usb/rio500 c 180 64
 
-Set appropriate permissions for /dev/usb/rio500 (don't forget about
-group and world permissions).  Both read and write permissions are
+In that case, set appropriate permissions for /dev/usb/rio500 (don't forget
+about group and world permissions).  Both read and write permissions are
 required for proper operation.
 
-Load the appropriate modules (if compiled as modules):
-
-  OHCI:
-    modprobe usbcore
-    modprobe usb-ohci
-    modprobe rio500
-
-  UHCI:
-    modprobe usbcore
-    modprobe usb-uhci  (or uhci)
-    modprobe rio500
-
 That's it.  The Rio500 Utils at: http://rio500.sourceforge.net should
 be able to access the rio500.

 1. Prepare

 Mount debugfs (it has to be enabled in your kernel configuration), and
 load the usbmon module (if built as module). The second step is skipped

 Now you can choose to either use the socket '0u' (to capture packets on all
 buses), and skip to step #3, or find the bus used by your device with step #2.
 This allows to filter away annoying devices that talk continuously.
 
 2. Find which bus connects to the desired device
+------------------------------------------------
 
 Run "cat /sys/kernel/debug/usb/devices", and find the T-line which corresponds
 to the device. Usually you do it by looking for the vendor string. If you have
 many similar devices, unplug one and compare the two
 /sys/kernel/debug/usb/devices outputs. The T-line will have a bus number.
-Example:
 
-T:  Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
-D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1

+  S:  Manufacturer=ATEN

 "Bus=03" means it's bus 3. Alternatively, you can look at the output from
 "lsusb" and get the bus number from the appropriate line. Example:

 redirected to a desirable location. This is preferred, because it is going
 to be quite long.

+
+KVM_REG_ARM64_SVE_VLS is a pseudo-register that allows the set of vector
+lengths supported by the vcpu to be discovered and configured by
+userspace.  When transferred to or from user memory via KVM_GET_ONE_REG
+or KVM_SET_ONE_REG, the value of this register is of type
+__u64[KVM_ARM64_SVE_VLS_WORDS], and encodes the set of vector lengths as

+	/* Vector length vq * 16 bytes supported */
+else
+	/* Vector length vq * 16 bytes not supported */
+
+(**) The maximum value vq for which the above condition is true is
+max_vq.  This is the maximum vector length available to the guest on
+this vcpu, and determines which register slices are visible through
+this ioctl interface.
+
+(See Documentation/arm64/sve.txt for an explanation of the "vq"
+nomenclature.)
+
+KVM_REG_ARM64_SVE_VLS is only accessible after KVM_ARM_VCPU_INIT.
+KVM_ARM_VCPU_INIT initialises it to the best set of vector lengths that
+the host supports.
+
+Userspace may subsequently modify it if desired until the vcpu's SVE
+configuration is finalized using KVM_ARM_VCPU_FINALIZE(KVM_ARM_VCPU_SVE).
+
+Apart from simply removing all vector lengths from the host set that
+exceed some value, support for arbitrarily chosen sets of vector lengths
+is hardware-dependent and may not be available.  Attempting to configure
+an invalid set of vector lengths via KVM_SET_ONE_REG will fail with
+EINVAL.
+
+After the vcpu's SVE configuration is finalized, further attempts to

+POWER9 eXternal Interrupt Virtualization Engine (XIVE Gen1)
+==========================================================
+
+Device types supported:
+  KVM_DEV_TYPE_XIVE     POWER9 XIVE Interrupt Controller generation 1
+
+This device acts as a VM interrupt controller. It provides the KVM
+interface to configure the interrupt sources of a VM in the underlying
+POWER9 XIVE interrupt controller.
+
+Only one XIVE instance may be instantiated. A guest XIVE device
+requires a POWER9 host and the guest OS should have support for the
+XIVE native exploitation interrupt mode. If not, it should run using
+the legacy interrupt mode, referred as XICS (POWER7/8).
+
+* Device Mappings
+
+  The KVM device exposes different MMIO ranges of the XIVE HW which
+  are required for interrupt management. These are exposed to the
+  guest in VMAs populated with a custom VM fault handler.
+
+  1. Thread Interrupt Management Area (TIMA)
+
+  Each thread has an associated Thread Interrupt Management context
+  composed of a set of registers. These registers let the thread
+  handle priority management and interrupt acknowledgment. The most
+  important are :
+
+      - Interrupt Pending Buffer     (IPB)
+      - Current Processor Priority   (CPPR)
+      - Notification Source Register (NSR)
+
+  They are exposed to software in four different pages each proposing
+  a view with a different privilege. The first page is for the
+  physical thread context and the second for the hypervisor. Only the
+  third (operating system) and the fourth (user level) are exposed the
+  guest.
+
+  2. Event State Buffer (ESB)
+
+  Each source is associated with an Event State Buffer (ESB) with
+  either a pair of even/odd pair of pages which provides commands to
+  manage the source: to trigger, to EOI, to turn off the source for
+  instance.
+
+  3. Device pass-through
+
+  When a device is passed-through into the guest, the source
+  interrupts are from a different HW controller (PHB4) and the ESB
+  pages exposed to the guest should accommadate this change.
+
+  The passthru_irq helpers, kvmppc_xive_set_mapped() and
+  kvmppc_xive_clr_mapped() are called when the device HW irqs are
+  mapped into or unmapped from the guest IRQ number space. The KVM
+  device extends these helpers to clear the ESB pages of the guest IRQ
+  number being mapped and then lets the VM fault handler repopulate.
+  The handler will insert the ESB page corresponding to the HW
+  interrupt of the device being passed-through or the initial IPI ESB
+  page if the device has being removed.
+
+  The ESB remapping is fully transparent to the guest and the OS
+  device driver. All handling is done within VFIO and the above
+  helpers in KVM-PPC.
+
+* Groups:
+
+  1. KVM_DEV_XIVE_GRP_CTRL

+  - type:  0:MSI 1:LSI
+  - level: assertion level in case of an LSI.
+  Errors:

+    -ENOMEM: Could not create a new source block
+    -EFAULT: Invalid user pointer for attr->addr.
+    -ENXIO:  Could not allocate underlying HW interrupt

+
+  4. KVM_DEV_XIVE_GRP_EQ_CONFIG (read-write)
+  Configures an event queue of a CPU
+  Attributes:
+    EQ descriptor identifier (64-bit)
+  The EQ descriptor identifier is a tuple (server, priority) :

+  values:   |    unused     |  server | priority
+  The kvm_device_attr.addr points to :
+    struct kvm_ppc_xive_eq {
+	__u32 flags;
+	__u32 qshift;

+  Attributes:
+    Interrupt source number  (64-bit)
+  Errors:
+    -ENOENT: Unknown source number
+    -EINVAL: Not initialized source number
+
+* VCPU state
+
+  The XIVE IC maintains VP interrupt state in an internal structure
+  called the NVT. When a VP is not dispatched on a HW processor
+  thread, this structure can be updated by HW if the VP is the target
+  of an event notification.
+
+  It is important for migration to capture the cached IPB from the NVT
+  as it synthesizes the priorities of the pending interrupts. We
+  capture a bit more to report debug information.
+
+  KVM_REG_PPC_VP_STATE (2 * 64bits)
+  bits:     |  63  ....  32  |  31  ....  0  |
+  values:   |   TIMA word0   |   TIMA word1  |

+  values:   |            unused              |
+
+* Migration:
+
+  Saving the state of a VM using the XIVE native exploitation mode
+  should follow a specific sequence. When the VM is stopped :
+
+  1. Mask all sources (PQ=01) to stop the flow of events.
+
+  2. Sync the XIVE device with the KVM control KVM_DEV_XIVE_EQ_SYNC to
+  flush any in-flight event notification and to stabilize the EQs. At
+  this stage, the EQ pages are marked dirty to make sure they are
+  transferred in the migration sequence.
+
+  3. Capture the state of the source targeting, the EQs configuration
+  and the state of thread interrupt context registers.
+
+  Restore is similar :
+
+  1. Restore the EQ configuration. As targeting depends on it.
+  2. Restore targeting
+  3. Restore the thread interrupt contexts
+  4. Restore the source states
+  5. Let the vCPU run

+=====================
+Physical Memory Model
+=====================
+
+Physical memory in a system may be addressed in different ways. The
+simplest case is when the physical memory starts at address 0 and
+spans a contiguous range up to the maximal address. It could be,
+however, that this range contains small holes that are not accessible
+for the CPU. Then there could be several contiguous ranges at
+completely distinct addresses. And, don't forget about NUMA, where
+different memory banks are attached to different CPUs.
+
+Linux abstracts this diversity using one of the three memory models:
+FLATMEM, DISCONTIGMEM and SPARSEMEM. Each architecture defines what
+memory models it supports, what the default memory model is and
+whether it is possible to manually override that default.
+
+.. note::
+   At time of this writing, DISCONTIGMEM is considered deprecated,
+   although it is still in use by several architectures.
+
+All the memory models track the status of physical page frames using
+:c:type:`struct page` arranged in one or more arrays.
+
+Regardless of the selected memory model, there exists one-to-one
+mapping between the physical page frame number (PFN) and the
+corresponding `struct page`.
+
+Each memory model defines :c:func:`pfn_to_page` and :c:func:`page_to_pfn`
+helpers that allow the conversion from PFN to `struct page` and vice
+versa.
+
+FLATMEM
+=======
+
+The simplest memory model is FLATMEM. This model is suitable for
+non-NUMA systems with contiguous, or mostly contiguous, physical
+memory.
+
+In the FLATMEM memory model, there is a global `mem_map` array that
+maps the entire physical memory. For most architectures, the holes
+have entries in the `mem_map` array. The `struct page` objects
+corresponding to the holes are never fully initialized.
+
+To allocate the `mem_map` array, architecture specific setup code
+should call :c:func:`free_area_init_node` function or its convenience
+wrapper :c:func:`free_area_init`. Yet, the mappings array is not
+usable until the call to :c:func:`memblock_free_all` that hands all
+the memory to the page allocator.
+
+If an architecture enables `CONFIG_ARCH_HAS_HOLES_MEMORYMODEL` option,
+it may free parts of the `mem_map` array that do not cover the
+actual physical pages. In such case, the architecture specific
+:c:func:`pfn_valid` implementation should take the holes in the
+`mem_map` into account.
+
+With FLATMEM, the conversion between a PFN and the `struct page` is
+straightforward: `PFN - ARCH_PFN_OFFSET` is an index to the
+`mem_map` array.
+
+The `ARCH_PFN_OFFSET` defines the first page frame number for
+systems with physical memory starting at address different from 0.
+
+DISCONTIGMEM
+============
+
+The DISCONTIGMEM model treats the physical memory as a collection of
+`nodes` similarly to how Linux NUMA support does. For each node Linux
+constructs an independent memory management subsystem represented by
+`struct pglist_data` (or `pg_data_t` for short). Among other
+things, `pg_data_t` holds the `node_mem_map` array that maps
+physical pages belonging to that node. The `node_start_pfn` field of
+`pg_data_t` is the number of the first page frame belonging to that
+node.
+
+The architecture setup code should call :c:func:`free_area_init_node` for
+each node in the system to initialize the `pg_data_t` object and its
+`node_mem_map`.
+
+Every `node_mem_map` behaves exactly as FLATMEM's `mem_map` -
+every physical page frame in a node has a `struct page` entry in the
+`node_mem_map` array. When DISCONTIGMEM is enabled, a portion of the
+`flags` field of the `struct page` encodes the node number of the
+node hosting that page.
+
+The conversion between a PFN and the `struct page` in the
+DISCONTIGMEM model became slightly more complex as it has to determine
+which node hosts the physical page and which `pg_data_t` object
+holds the `struct page`.
+
+Architectures that support DISCONTIGMEM provide :c:func:`pfn_to_nid`
+to convert PFN to the node number. The opposite conversion helper
+:c:func:`page_to_nid` is generic as it uses the node number encoded in
+page->flags.
+
+Once the node number is known, the PFN can be used to index
+appropriate `node_mem_map` array to access the `struct page` and
+the offset of the `struct page` from the `node_mem_map` plus
+`node_start_pfn` is the PFN of that page.
+
+SPARSEMEM
+=========
+
+SPARSEMEM is the most versatile memory model available in Linux and it
+is the only memory model that supports several advanced features such
+as hot-plug and hot-remove of the physical memory, alternative memory
+maps for non-volatile memory devices and deferred initialization of
+the memory map for larger systems.
+
+The SPARSEMEM model presents the physical memory as a collection of
+sections. A section is represented with :c:type:`struct mem_section`
+that contains `section_mem_map` that is, logically, a pointer to an
+array of struct pages. However, it is stored with some other magic
+that aids the sections management. The section size and maximal number
+of section is specified using `SECTION_SIZE_BITS` and
+`MAX_PHYSMEM_BITS` constants defined by each architecture that
+supports SPARSEMEM. While `MAX_PHYSMEM_BITS` is an actual width of a
+physical address that an architecture supports, the
+`SECTION_SIZE_BITS` is an arbitrary value.
+
+The maximal number of sections is denoted `NR_MEM_SECTIONS` and
+defined as
+
+.. math::
+
+   NR\_MEM\_SECTIONS = 2 ^ {(MAX\_PHYSMEM\_BITS - SECTION\_SIZE\_BITS)}
+
+The `mem_section` objects are arranged in a two-dimensional array
+called `mem_sections`. The size and placement of this array depend
+on `CONFIG_SPARSEMEM_EXTREME` and the maximal possible number of
+sections:
+
+* When `CONFIG_SPARSEMEM_EXTREME` is disabled, the `mem_sections`
+  array is static and has `NR_MEM_SECTIONS` rows. Each row holds a
+  single `mem_section` object.
+* When `CONFIG_SPARSEMEM_EXTREME` is enabled, the `mem_sections`
+  array is dynamically allocated. Each row contains PAGE_SIZE worth of
+  `mem_section` objects and the number of rows is calculated to fit
+  all the memory sections.
+
+The architecture setup code should call :c:func:`memory_present` for
+each active memory range or use :c:func:`memblocks_present` or
+:c:func:`sparse_memory_present_with_active_regions` wrappers to
+initialize the memory sections. Next, the actual memory maps should be
+set up using :c:func:`sparse_init`.
+
+With SPARSEMEM there are two possible ways to convert a PFN to the
+corresponding `struct page` - a "classic sparse" and "sparse
+vmemmap". The selection is made at build time and it is determined by
+the value of `CONFIG_SPARSEMEM_VMEMMAP`.
+
+The classic sparse encodes the section number of a page in page->flags
+and uses high bits of a PFN to access the section that maps that page
+frame. Inside a section, the PFN is the index to the array of pages.
+
+The sparse vmemmap uses a virtually mapped memory map to optimize
+pfn_to_page and page_to_pfn operations. There is a global `struct
+page *vmemmap` pointer that points to a virtually contiguous array of
+`struct page` objects. A PFN is an index to that array and the the
+offset of the `struct page` from `vmemmap` is the PFN of that
+page.
+
+To use vmemmap, an architecture has to reserve a range of virtual
+addresses that will map the physical pages containing the memory
+map and make sure that `vmemmap` points to that range. In addition,
+the architecture should implement :c:func:`vmemmap_populate` method
+that will allocate the physical memory and create page tables for the
+virtual memory map. If an architecture does not have any special
+requirements for the vmemmap mappings, it can use default
+:c:func:`vmemmap_populate_basepages` provided by the generic memory
+management.
+
+The virtually mapped memory map allows storing `struct page` objects
+for persistent memory devices in pre-allocated storage on those
+devices. This storage is represented with :c:type:`struct vmem_altmap`
+that is eventually passed to vmemmap_populate() through a long chain
+of function calls. The vmemmap_populate() implementation may use the
+`vmem_altmap` along with :c:func:`altmap_alloc_block_buf` helper to
+allocate memory map on the persistent memory device.

+=====================
+AMD Memory Encryption
+=====================
+
+Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV) are
+features found on AMD processors.
+
+SME provides the ability to mark individual pages of memory as encrypted using
+the standard x86 page tables.  A page that is marked encrypted will be
+automatically decrypted when read from DRAM and encrypted when written to
+DRAM.  SME can therefore be used to protect the contents of DRAM from physical
+attacks on the system.
+
+SEV enables running encrypted virtual machines (VMs) in which the code and data
+of the guest VM are secured so that a decrypted version is available only
+within the VM itself. SEV guest VMs have the concept of private and shared
+memory. Private memory is encrypted with the guest-specific key, while shared
+memory may be encrypted with hypervisor key. When SME is enabled, the hypervisor
+key is the same key which is used in SME.
+
+A page is encrypted when a page table entry has the encryption bit set (see
+below on how to determine its position).  The encryption bit can also be
+specified in the cr3 register, allowing the PGD table to be encrypted. Each
+successive level of page tables can also be encrypted by setting the encryption
+bit in the page table entry that points to the next table. This allows the full
+page table hierarchy to be encrypted. Note, this means that just because the
+encryption bit is set in cr3, doesn't imply the full hierarchy is encrypted.
+Each page table entry in the hierarchy needs to have the encryption bit set to
+achieve that. So, theoretically, you could have the encryption bit set in cr3
+so that the PGD is encrypted, but not set the encryption bit in the PGD entry
+for a PUD which results in the PUD pointed to by that entry to not be
+encrypted.
+
+When SEV is enabled, instruction pages and guest page tables are always treated
+as private. All the DMA operations inside the guest must be performed on shared
+memory. Since the memory encryption bit is controlled by the guest OS when it
+is operating in 64-bit or 32-bit PAE mode, in all other modes the SEV hardware
+forces the memory encryption bit to 1.
+
+Support for SME and SEV can be determined through the CPUID instruction. The
+CPUID function 0x8000001f reports information related to SME::
+
+	0x8000001f[eax]:
+		Bit[0] indicates support for SME
+		Bit[1] indicates support for SEV
+	0x8000001f[ebx]:
+		Bits[5:0]  pagetable bit number used to activate memory
+			   encryption
+		Bits[11:6] reduction in physical address space, in bits, when
+			   memory encryption is enabled (this only affects
+			   system physical addresses, not guest physical
+			   addresses)
+
+If support for SME is present, MSR 0xc00100010 (MSR_K8_SYSCFG) can be used to
+determine if SME is enabled and/or to enable memory encryption::
+
+	0xc0010010:
+		Bit[23]   0 = memory encryption features are disabled
+			  1 = memory encryption features are enabled
+
+If SEV is supported, MSR 0xc0010131 (MSR_AMD64_SEV) can be used to determine if
+SEV is active::
+
+	0xc0010131:
+		Bit[0]	  0 = memory encryption is not active
+			  1 = memory encryption is active
+
+Linux relies on BIOS to set this bit if BIOS has determined that the reduction
+in the physical address space as a result of enabling memory encryption (see
+CPUID information above) will not conflict with the address space resource
+requirements for the system.  If this bit is not set upon Linux startup then
+Linux itself will not set it and memory encryption will not be possible.
+
+The state of SME in the Linux kernel can be documented as follows:
+
+	- Supported:
+	  The CPU supports SME (determined through CPUID instruction).
+
+	- Enabled:
+	  Supported and bit 23 of MSR_K8_SYSCFG is set.
+
+	- Active:
+	  Supported, Enabled and the Linux kernel is actively applying
+	  the encryption bit to page table entries (the SME mask in the
+	  kernel is non-zero).
+
+SME can also be enabled and activated in the BIOS. If SME is enabled and
+activated in the BIOS, then all memory accesses will be encrypted and it will
+not be necessary to activate the Linux memory encryption support.  If the BIOS
+merely enables SME (sets bit 23 of the MSR_K8_SYSCFG), then Linux can activate
+memory encryption by default (CONFIG_AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT=y) or
+by supplying mem_encrypt=on on the kernel command line.  However, if BIOS does
+not enable SME, then Linux will not be able to activate memory encryption, even
+if configured to do so by default or the mem_encrypt=on command line parameter

+
+Memory Layout
+=============
+
+The traditional memory map for the kernel loader, used for Image or
+zImage kernels, typically looks like::
+
+		|			 |
+	0A0000	+------------------------+
+		|  Reserved for BIOS	 |	Do not use.  Reserved for BIOS EBDA.
+	09A000	+------------------------+
+		|  Command line		 |
+		|  Stack/heap		 |	For use by the kernel real-mode code.
+	098000	+------------------------+
+		|  Kernel setup		 |	The kernel real-mode code.
+	090200	+------------------------+
+		|  Kernel boot sector	 |	The kernel legacy boot sector.
+	090000	+------------------------+
+		|  Protected-mode kernel |	The bulk of the kernel image.
+	010000	+------------------------+
+		|  Boot loader		 |	<- Boot sector entry point 0000:7C00
+	001000	+------------------------+
+		|  Reserved for MBR/BIOS |
+	000800	+------------------------+
+		|  Typically used by MBR |
+	000600	+------------------------+
+		|  BIOS use only	 |
+	000000	+------------------------+
+
+When using bzImage, the protected-mode kernel was relocated to
+0x100000 ("high memory"), and the kernel real-mode block (boot sector,
+setup, and stack/heap) was made relocatable to any address between
+0x10000 and end of low memory. Unfortunately, in protocols 2.00 and
+2.01 the 0x90000+ memory range is still used internally by the kernel;
+the 2.02 protocol resolves that problem.
+
+It is desirable to keep the "memory ceiling" -- the highest point in
+low memory touched by the boot loader -- as low as possible, since
+some newer BIOSes have begun to allocate some rather large amounts of
+memory, called the Extended BIOS Data Area, near the top of low
+memory.	 The boot loader should use the "INT 12h" BIOS call to verify
+how much low memory is available.
+
+Unfortunately, if INT 12h reports that the amount of memory is too
+low, there is usually nothing the boot loader can do but to report an
+error to the user.  The boot loader should therefore be designed to
+take up as little space in low memory as it reasonably can.  For
+zImage or old bzImage kernels, which need data written into the
+0x90000 segment, the boot loader should make sure not to use memory
+above the 0x9A000 point; too many BIOSes will break above that point.
+
+For a modern bzImage kernel with boot protocol version >= 2.02, a
+memory layout like the following is suggested::
+
+		~                        ~
+		|  Protected-mode kernel |
+	100000  +------------------------+
+		|  I/O memory hole	 |
+	0A0000	+------------------------+
+		|  Reserved for BIOS	 |	Leave as much as possible unused
+		~                        ~
+		|  Command line		 |	(Can also be below the X+10000 mark)
+	X+10000	+------------------------+
+		|  Stack/heap		 |	For use by the kernel real-mode code.
+	X+08000	+------------------------+
+		|  Kernel setup		 |	The kernel real-mode code.
+		|  Kernel boot sector	 |	The kernel legacy boot sector.
+	X       +------------------------+
+		|  Boot loader		 |	<- Boot sector entry point 0000:7C00
+	001000	+------------------------+
+		|  Reserved for MBR/BIOS |
+	000800	+------------------------+
+		|  Typically used by MBR |
+	000600	+------------------------+
+		|  BIOS use only	 |
+	000000	+------------------------+
+
+  ... where the address X is as low as the design of the boot loader permits.
+
+
+The Real-Mode Kernel Header
+===========================
+
+In the following text, and anywhere in the kernel boot sequence, "a
+sector" refers to 512 bytes.  It is independent of the actual sector
+size of the underlying medium.
+
+The first step in loading a Linux kernel should be to load the
+real-mode code (boot sector and setup code) and then examine the
+following header at offset 0x01f1.  The real-mode code can total up to
+32K, although the boot loader may choose to load only the first two
+sectors (1K) and then examine the bootup sector size.
+
+The header looks like:
+
+===========	========	=====================	============================================
+Offset/Size	Proto		Name			Meaning
+===========	========	=====================	============================================
+01F1/1		ALL(1)		setup_sects		The size of the setup in sectors

+0236/2		2.12+		xloadflags		Boot protocol option flags
+0238/4		2.06+		cmdline_size		Maximum size of the kernel command line

+0264/4		2.11+		handover_offset		Offset of handover entry point
+===========	========	=====================	============================================
+
+.. note::
+  (1) For backwards compatibility, if the setup_sects field contains 0, the
+      real value is 4.
+
+  (2) For boot protocol prior to 2.04, the upper two bytes of the syssize
+      field are unusable, which means the size of a bzImage kernel
+      cannot be determined.
+
+  (3) Ignored, but safe to set, for boot protocols 2.02-2.09.
+
+If the "HdrS" (0x53726448) magic number is not found at offset 0x202,
+the boot protocol version is "old".  Loading an old kernel, the
+following parameters should be assumed::
+
+	Image type = zImage
+	initrd not supported
+	Real-mode kernel must be located at 0x90000.
+
+Otherwise, the "version" field contains the protocol version,
+e.g. protocol version 2.01 will contain 0x0201 in this field.  When
+setting fields in the header, you must make sure only to set fields
+supported by the protocol version in use.
+
+
+Details of Harder Fileds
+========================
+
+For each field, some are information from the kernel to the bootloader
+("read"), some are expected to be filled out by the bootloader
+("write"), and some are expected to be read and modified by the
+bootloader ("modify").
+
+All general purpose boot loaders should write the fields marked
+(obligatory).  Boot loaders who want to load the kernel at a
+nonstandard address should fill in the fields marked (reloc); other
+boot loaders can ignore those fields.
+
+The byte order of all fields is littleendian (this is x86, after all.)
+
+============	===========
+Field name:	setup_sects
+Type:		read
+Offset/size:	0x1f1/1
+Protocol:	ALL
+============	===========
+
+  The size of the setup code in 512-byte sectors.  If this field is

+Field name:	syssize
+Type:		read
+Offset/size:	0x1f4/4 (protocol 2.04+) 0x1f4/2 (protocol ALL)
+Protocol:	2.04+
+============	===============================================
+
+  The size of the protected-mode code in units of 16-byte paragraphs.
+  For protocol versions older than 2.04 this field is only two bytes
+  wide, and therefore cannot be trusted for the size of a kernel if
+  the LOAD_HIGH flag is set.
+

+============	=======
+Field name:	jump
+Type:		read
+Offset/size:	0x200/2
+Protocol:	2.00+
+============	=======
+
+  Contains an x86 jump instruction, 0xEB followed by a signed offset

+
+============	=======
+Field name:	header
+Type:		read
+Offset/size:	0x202/4
+Protocol:	2.00+

+============	=======
+Field name:	version
+Type:		read
+Offset/size:	0x206/2
+Protocol:	2.00+
+============	=======
+
+  Contains the boot protocol version, in (major << 8)+minor format,
+  e.g. 0x0204 for version 2.04, and 0x0a11 for a hypothetical version
+  10.17.

+
+============	==============
+Field name:	kernel_version
+Type:		read
+Offset/size:	0x20e/2
+Protocol:	2.00+
+============	==============
+
+  If set to a nonzero value, contains a pointer to a NUL-terminated
+  human-readable kernel version number string, less 0x200.  This can
+  be used to display the kernel version to the user.  This value
+  should be less than (0x200*setup_sects).
+
+  For example, if this value is set to 0x1c00, the kernel version
+  number string can be found at offset 0x1e00 in the kernel file.
+  This is a valid value if and only if the "setup_sects" field
+  contains the value 15 or higher, as::
+
+	0x1c00  < 15*0x200 (= 0x1e00) but
+	0x1c00 >= 14*0x200 (= 0x1c00)
+
+	0x1c00 >> 9 = 14, So the minimum value for setup_secs is 15.

+  loader to modify this field to permit a lesser alignment.  See the
+  min_alignment and pref_address field below.

+============	==================
+Field name:	relocatable_kernel
+Type:		read (reloc)
+Offset/size:	0x234/1
+Protocol:	2.05+
+============	==================
+
+  If this field is nonzero, the protected-mode part of the kernel can
+  be loaded at any address that satisfies the kernel_alignment field.
+  After loading, the boot loader must set the code32_start field to
+  point to the loaded code, or to a boot loader hook.
+
+============	=============
+Field name:	min_alignment
+Type:		read (reloc)
+Offset/size:	0x235/1
+Protocol:	2.10+
+============	=============
+
+  This field, if nonzero, indicates as a power of two the minimum
+  alignment required, as opposed to preferred, by the kernel to boot.
+  If a boot loader makes use of this field, it should update the
+  kernel_alignment field with the alignment unit desired; typically::
+
+	kernel_alignment = 1 << min_alignment
+
+  There may be a considerable performance cost with an excessively
+  misaligned kernel.  Therefore, a loader should typically try each
+  power-of-two alignment from kernel_alignment down to this alignment.

+Type:		read
+Offset/size:	0x238/4
+Protocol:	2.06+
+============	============
+
+  The maximum size of the command line without the terminating
+  zero. This means that the command line can contain at most
+  cmdline_size characters. With protocol version 2.05 and earlier, the
+  maximum size was 255.

+
+  In a paravirtualized environment the hardware low level architectural
+  pieces such as interrupt handling, page table handling, and
+  accessing process control registers needs to be done differently.
+
+  This field allows the bootloader to inform the kernel we are in one

+Field name:	payload_offset
+Type:		read
+Offset/size:	0x248/4
+Protocol:	2.08+
+============	==============
+
+  If non-zero then this field contains the offset from the beginning
+  of the protected-mode code to the payload.
+
+  The payload may be compressed. The format of both the compressed and
+  uncompressed data should be determined using the standard magic
+  numbers.  The currently supported compression formats are gzip
+  (magic numbers 1F 8B or 1F 9E), bzip2 (magic number 42 5A), LZMA
+  (magic number 5D 00), XZ (magic number FD 37), and LZ4 (magic number
+  02 21).  The uncompressed payload is currently always ELF (magic
+  number 7F 45 4C 46).
+

+
+  The length of the payload.

+============	===============
+Field name:	setup_data
+Type:		write (special)
+Offset/size:	0x250/8
+Protocol:	2.09+
+============	===============
+
+  The 64-bit physical pointer to NULL terminated single linked list of
+  struct setup_data. This is used to define a more extensible boot
+  parameters passing mechanism. The definition of struct setup_data is
+  as follow::
+
+	struct setup_data {
+		u64 next;
+		u32 type;
+		u32 len;
+		u8  data[0];
+	};
+
+  Where, the next is a 64-bit physical pointer to the next node of
+  linked list, the next field of the last node is 0; the type is used
+  to identify the contents of data; the len is the length of data
+  field; the data holds the real payload.
+
+  This list may be modified at a number of points during the bootup
+  process.  Therefore, when modifying this list one should always make
+  sure to consider the case where the linked list already contains
+  entries.
+
+============	============
+Field name:	pref_address
+Type:		read (reloc)
+Offset/size:	0x258/8
+Protocol:	2.10+
+============	============
+
+  This field, if nonzero, represents a preferred load address for the
+  kernel.  A relocating bootloader should attempt to load at this
+  address if possible.
+
+  A non-relocatable kernel will unconditionally move itself and to run
+  at this address.
+
+============	=======
+Field name:	init_size
+Type:		read
+Offset/size:	0x260/4
+============	=======
+
+  This field indicates the amount of linear contiguous memory starting
+  at the kernel runtime start address that the kernel needs before it
+  is capable of examining its memory map.  This is not the same thing
+  as the total amount of memory the kernel needs to boot, but it can
+  be used by a relocating boot loader to help select a safe load
+  address for the kernel.
+
+  The kernel runtime start address is determined by the following algorithm::
+
+	if (relocatable_kernel)
+	runtime_start = align_up(load_address, kernel_alignment)
+	else
+	runtime_start = pref_address
+
+============	===============
+Field name:	handover_offset
+Type:		read
+Offset/size:	0x264/4
+============	===============
+
+  This field is the offset from the beginning of the kernel image to
+  the EFI handover protocol entry point. Boot loaders using the EFI
+  handover protocol to boot the kernel should jump to this offset.
+
+  See EFI HANDOVER PROTOCOL below for more details.
+
+
+The Image Checksum
+==================
+
+From boot protocol version 2.08 onwards the CRC-32 is calculated over
+the entire file using the characteristic polynomial 0x04C11DB7 and an
+initial remainder of 0xffffffff.  The checksum is appended to the
+file; therefore the CRC of the file up to the limit specified in the
+syssize field of the header is always 0.
+
+
+The Kernel Command Line
+=======================
+
+The kernel command line has become an important way for the boot
+loader to communicate with the kernel.  Some of its options are also
+relevant to the boot loader itself, see "special command line options"
+below.
+
+The kernel command line is a null-terminated string. The maximum
+length can be retrieved from the field cmdline_size.  Before protocol
+version 2.06, the maximum was 255 characters.  A string that is too
+long will be automatically truncated by the kernel.
+
+If the boot protocol version is 2.02 or later, the address of the
+kernel command line is given by the header field cmd_line_ptr (see
+above.)  This address can be anywhere between the end of the setup
+heap and 0xA0000.
+
+If the protocol version is *not* 2.02 or higher, the kernel
+command line is entered using the following protocol:
+
+  - At offset 0x0020 (word), "cmd_line_magic", enter the magic
+    number 0xA33F.
+
+  - At offset 0x0022 (word), "cmd_line_offset", enter the offset
+    of the kernel command line (relative to the start of the
+    real-mode kernel).
+
+  - The kernel command line *must* be within the memory region
+    covered by setup_move_size, so you may need to adjust this
+    field.
+
+
+Memory Layout of The Real-Mode Code
+===================================
+
+The real-mode code requires a stack/heap to be set up, as well as
+memory allocated for the kernel command line.  This needs to be done
+in the real-mode accessible memory in bottom megabyte.
+
+It should be noted that modern machines often have a sizable Extended
+BIOS Data Area (EBDA).  As a result, it is advisable to use as little
+of the low megabyte as possible.
+
+Unfortunately, under the following circumstances the 0x90000 memory
+segment has to be used:
+
+	- When loading a zImage kernel ((loadflags & 0x01) == 0).
+	- When loading a 2.01 or earlier boot protocol kernel.
+
+.. note::
+     For the 2.00 and 2.01 boot protocols, the real-mode code
+     can be loaded at another address, but it is internally
+     relocated to 0x90000.  For the "old" protocol, the
+     real-mode code must be loaded at 0x90000.
+
+When loading at 0x90000, avoid using memory above 0x9a000.
+
+For boot protocol 2.02 or higher, the command line does not have to be
+located in the same 64K segment as the real-mode setup code; it is
+thus permitted to give the stack/heap the full 64K segment and locate
+the command line above it.
+
+The kernel command line should not be located below the real-mode
+code, nor should it be located in high memory.
+
+
+Sample Boot Configuartion
+=========================
+
+As a sample configuration, assume the following layout of the real
+mode segment.
+
+    When loading below 0x90000, use the entire segment:
+
+        =============	===================
+	0x0000-0x7fff	Real mode kernel
+	0x8000-0xdfff	Stack and heap
+	0xe000-0xffff	Kernel command line
+	=============	===================
+
+    When loading at 0x90000 OR the protocol version is 2.01 or earlier:
+
+	=============	===================
+	0x0000-0x7fff	Real mode kernel
+	0x8000-0x97ff	Stack and heap
+	0x9800-0x9fff	Kernel command line
+	=============	===================
+
+Such a boot loader should enter the following fields in the header::
+
+	unsigned long base_ptr;	/* base address for real-mode segment */
+
+	if ( setup_sects == 0 ) {
+		setup_sects = 4;
+	}
+
+	if ( protocol >= 0x0200 ) {
+		type_of_loader = <type code>;
+		if ( loading_initrd ) {
+			ramdisk_image = <initrd_address>;
+			ramdisk_size = <initrd_size>;
+		}
+
+		if ( protocol >= 0x0202 && loadflags & 0x01 )
+			heap_end = 0xe000;
+		else
+			heap_end = 0x9800;
+
+		if ( protocol >= 0x0201 ) {
+			heap_end_ptr = heap_end - 0x200;
+			loadflags |= 0x80; /* CAN_USE_HEAP */
+		}
+
+		if ( protocol >= 0x0202 ) {
+			cmd_line_ptr = base_ptr + heap_end;
+			strcpy(cmd_line_ptr, cmdline);
+		} else {
+			cmd_line_magic	= 0xA33F;
+			cmd_line_offset = heap_end;
+			setup_move_size = heap_end + strlen(cmdline)+1;
+			strcpy(base_ptr+cmd_line_offset, cmdline);
+		}
+	} else {
+		/* Very old kernel */
+
+		heap_end = 0x9800;
+
+		cmd_line_magic	= 0xA33F;
+		cmd_line_offset = heap_end;
+
+		/* A very old kernel MUST have its real-mode code
+		   loaded at 0x90000 */
+
+		if ( base_ptr != 0x90000 ) {
+			/* Copy the real-mode kernel */
+			memcpy(0x90000, base_ptr, (setup_sects+1)*512);
+			base_ptr = 0x90000;		 /* Relocated */
+		}
+
+		strcpy(0x90000+cmd_line_offset, cmdline);
+
+		/* It is recommended to clear memory up to the 32K mark */
+		memset(0x90000 + (setup_sects+1)*512, 0,
+		       (64-(setup_sects+1))*512);
+	}
+
+
+Loading The Rest of The Kernel
+==============================
+
+The 32-bit (non-real-mode) kernel starts at offset (setup_sects+1)*512
+in the kernel file (again, if setup_sects == 0 the real value is 4.)
+It should be loaded at address 0x10000 for Image/zImage kernels and
+0x100000 for bzImage kernels.
+
+The kernel is a bzImage kernel if the protocol >= 2.00 and the 0x01
+bit (LOAD_HIGH) in the loadflags field is set::
+
+	is_bzImage = (protocol >= 0x0200) && (loadflags & 0x01);
+	load_address = is_bzImage ? 0x100000 : 0x10000;
+
+Note that Image/zImage kernels can be up to 512K in size, and thus use
+the entire 0x10000-0x90000 range of memory.  This means it is pretty
+much a requirement for these kernels to load the real-mode part at
+0x90000.  bzImage kernels allow much more flexibility.
+
+Special Command Line Options
+============================
+
+If the command line provided by the boot loader is entered by the
+user, the user may expect the following command line options to work.
+They should normally not be deleted from the kernel command line even
+though not all of them are actually meaningful to the kernel.  Boot
+loader authors who need additional command line options for the boot
+loader itself should get them registered in
+Documentation/admin-guide/kernel-parameters.rst to make sure they will not
+conflict with actual kernel options now or in the future.
+
+  vga=<mode>
+	<mode> here is either an integer (in C notation, either
+	decimal, octal, or hexadecimal) or one of the strings
+	"normal" (meaning 0xFFFF), "ext" (meaning 0xFFFE) or "ask"
+	(meaning 0xFFFD).  This value should be entered into the
+	vid_mode field, as it is used by the kernel before the command
+	line is parsed.
+
+  mem=<size>
+	<size> is an integer in C notation optionally followed by
+	(case insensitive) K, M, G, T, P or E (meaning << 10, << 20,
+	<< 30, << 40, << 50 or << 60).  This specifies the end of
+	memory to the kernel. This affects the possible placement of
+	an initrd, since an initrd should be placed near end of
+	memory.  Note that this is an option to *both* the kernel and
+	the bootloader!
+
+  initrd=<file>
+	An initrd should be loaded.  The meaning of <file> is
+	obviously bootloader-dependent, and some boot loaders
+	(e.g. LILO) do not have such a command.
+
+In addition, some boot loaders add the following options to the
+user-specified command line:
+
+  BOOT_IMAGE=<file>
+	The boot image which was loaded.  Again, the meaning of <file>
+	is obviously bootloader-dependent.
+
+  auto
+	The kernel was booted without explicit user intervention.
+
+If these options are added by the boot loader, it is highly
+recommended that they are located *first*, before the user-specified
+or configuration-specified command line.  Otherwise, "init=/bin/sh"
+gets confused by the "auto" option.
+
+
+Running the Kernel
+==================
+
+The kernel is started by jumping to the kernel entry point, which is
+located at *segment* offset 0x20 from the start of the real mode
+kernel.  This means that if you loaded your real-mode kernel code at
+0x90000, the kernel entry point is 9020:0000.
+
+At entry, ds = es = ss should point to the start of the real-mode
+kernel code (0x9000 if the code is loaded at 0x90000), sp should be
+set up properly, normally pointing to the top of the heap, and
+interrupts should be disabled.  Furthermore, to guard against bugs in
+the kernel, it is recommended that the boot loader sets fs = gs = ds =
+es = ss.
+
+In our example from above, we would do::
+
+	/* Note: in the case of the "old" kernel protocol, base_ptr must
+	   be == 0x90000 at this point; see the previous sample code */
+
+	seg = base_ptr >> 4;
+
+	cli();	/* Enter with interrupts disabled! */
+
+	/* Set up the real-mode kernel stack */
+	_SS = seg;
+	_SP = heap_end;
+
+	_DS = _ES = _FS = _GS = seg;
+	jmp_far(seg+0x20, 0);	/* Run the kernel */
+
+If your boot sector accesses a floppy drive, it is recommended to
+switch off the floppy motor before running the kernel, since the
+kernel boot leaves interrupts off and thus the motor will not be
+switched off, especially if the loaded kernel has the floppy driver as
+a demand-loaded module!
+
+
+Advanced Boot Loader Hooks
+==========================
+
+If the boot loader runs in a particularly hostile environment (such as
+LOADLIN, which runs under DOS) it may be impossible to follow the
+standard memory location requirements.  Such a boot loader may use the
+following hooks that, if set, are invoked by the kernel at the
+appropriate time.  The use of these hooks should probably be
+considered an absolutely last resort!
+
+IMPORTANT: All the hooks are required to preserve %esp, %ebp, %esi and
+%edi across invocation.
+
+  realmode_swtch:
+	A 16-bit real mode far subroutine invoked immediately before
+	entering protected mode.  The default routine disables NMI, so
+	your routine should probably do so, too.
+
+  code32_start:
+	A 32-bit flat-mode routine *jumped* to immediately after the
+	transition to protected mode, but before the kernel is
+	uncompressed.  No segments, except CS, are guaranteed to be
+	set up (current kernels do, but older ones do not); you should
+	set them up to BOOT_DS (0x18) yourself.
+
+	After completing your hook, you should jump to the address
+	that was in this field before your boot loader overwrote it
+	(relocated, if appropriate.)
+
+
+32-bit Boot Protocol
+====================
+
+For machine with some new BIOS other than legacy BIOS, such as EFI,
+LinuxBIOS, etc, and kexec, the 16-bit real mode setup code in kernel
+based on legacy BIOS can not be used, so a 32-bit boot protocol needs
+to be defined.
+
+In 32-bit boot protocol, the first step in loading a Linux kernel
+should be to setup the boot parameters (struct boot_params,
+traditionally known as "zero page"). The memory for struct boot_params
+should be allocated and initialized to all zero. Then the setup header
+from offset 0x01f1 of kernel image on should be loaded into struct
+boot_params and examined. The end of setup header can be calculated as
+follow::
+
+	0x0202 + byte value at offset 0x0201
+
+In addition to read/modify/write the setup header of the struct
+boot_params as that of 16-bit boot protocol, the boot loader should
+also fill the additional fields of the struct boot_params as that
+described in zero-page.txt.
+
+After setting up the struct boot_params, the boot loader can load the
+32/64-bit kernel in the same way as that of 16-bit boot protocol.
+
+In 32-bit boot protocol, the kernel is started by jumping to the
+32-bit kernel entry point, which is the start address of loaded
+32/64-bit kernel.
+
+At entry, the CPU must be in 32-bit protected mode with paging
+disabled; a GDT must be loaded with the descriptors for selectors
+__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat
+segment; __BOOT_CS must have execute/read permission, and __BOOT_DS
+must have read/write permission; CS must be __BOOT_CS and DS, ES, SS
+must be __BOOT_DS; interrupt must be disabled; %esi must hold the base
+address of the struct boot_params; %ebp, %edi and %ebx must be zero.
+
+64-bit Boot Protocol
+====================
+
+For machine with 64bit cpus and 64bit kernel, we could use 64bit bootloader
+and we need a 64-bit boot protocol.
+
+In 64-bit boot protocol, the first step in loading a Linux kernel
+should be to setup the boot parameters (struct boot_params,
+traditionally known as "zero page"). The memory for struct boot_params
+could be allocated anywhere (even above 4G) and initialized to all zero.
+Then, the setup header at offset 0x01f1 of kernel image on should be
+loaded into struct boot_params and examined. The end of setup header
+can be calculated as follows::
+
+	0x0202 + byte value at offset 0x0201
+
+In addition to read/modify/write the setup header of the struct
+boot_params as that of 16-bit boot protocol, the boot loader should
+also fill the additional fields of the struct boot_params as described
+in zero-page.txt.
+
+After setting up the struct boot_params, the boot loader can load
+64-bit kernel in the same way as that of 16-bit boot protocol, but
+kernel could be loaded above 4G.
+
+In 64-bit boot protocol, the kernel is started by jumping to the
+64-bit kernel entry point, which is the start address of loaded
+64-bit kernel plus 0x200.
+
+At entry, the CPU must be in 64-bit mode with paging enabled.
+The range with setup_header.init_size from start address of loaded
+kernel and zero page and command line buffer get ident mapping;
+a GDT must be loaded with the descriptors for selectors
+__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat
+segment; __BOOT_CS must have execute/read permission, and __BOOT_DS
+must have read/write permission; CS must be __BOOT_CS and DS, ES, SS
+must be __BOOT_DS; interrupt must be disabled; %rsi must hold the base
+address of the struct boot_params.
+
+EFI Handover Protocol
+=====================
+
+This protocol allows boot loaders to defer initialisation to the EFI
+boot stub. The boot loader is required to load the kernel/initrd(s)
+from the boot media and jump to the EFI handover protocol entry point
+which is hdr->handover_offset bytes from the beginning of
+startup_{32,64}.
+
+The function prototype for the handover entry point looks like this::
+
+    efi_main(void *handle, efi_system_table_t *table, struct boot_params *bp)
+
+'handle' is the EFI image handle passed to the boot loader by the EFI
+firmware, 'table' is the EFI system table - these are the first two
+arguments of the "handoff state" as described in section 2.3 of the
+UEFI specification. 'bp' is the boot loader-allocated boot params.
+
+The boot loader *must* fill out the following fields in bp::
+
+  - hdr.code32_start
+  - hdr.cmd_line_ptr
+  - hdr.ramdisk_image (if applicable)
+  - hdr.ramdisk_size  (if applicable)
+
+All other fields should be zero.

-		     THE LINUX/x86 BOOT PROTOCOL
-		     ---------------------------
-
-On the x86 platform, the Linux kernel uses a rather complicated boot
-convention.  This has evolved partially due to historical aspects, as
-well as the desire in the early days to have the kernel itself be a
-bootable image, the complicated PC memory model and due to changed
-expectations in the PC industry caused by the effective demise of
-real-mode DOS as a mainstream operating system.
-
-Currently, the following versions of the Linux/x86 boot protocol exist.
-
-Old kernels:	zImage/Image support only.  Some very early kernels
-		may not even support a command line.
-
-Protocol 2.00:	(Kernel 1.3.73) Added bzImage and initrd support, as
-		well as a formalized way to communicate between the
-		boot loader and the kernel.  setup.S made relocatable,
-		although the traditional setup area still assumed
-		writable.
-
-Protocol 2.01:	(Kernel 1.3.76) Added a heap overrun warning.
-
-Protocol 2.02:	(Kernel 2.4.0-test3-pre3) New command line protocol.
-		Lower the conventional memory ceiling.	No overwrite
-		of the traditional setup area, thus making booting
-		safe for systems which use the EBDA from SMM or 32-bit
-		BIOS entry points.  zImage deprecated but still

-**** MEMORY LAYOUT
-
-The traditional memory map for the kernel loader, used for Image or
-zImage kernels, typically looks like:
-
-	|			 |
-0A0000	+------------------------+
-	|  Reserved for BIOS	 |	Do not use.  Reserved for BIOS EBDA.
-09A000	+------------------------+
-	|  Command line		 |
-	|  Stack/heap		 |	For use by the kernel real-mode code.
-098000	+------------------------+	
-	|  Kernel setup		 |	The kernel real-mode code.
-090200	+------------------------+
-	|  Kernel boot sector	 |	The kernel legacy boot sector.
-090000	+------------------------+
-	|  Protected-mode kernel |	The bulk of the kernel image.
-010000	+------------------------+
-	|  Boot loader		 |	<- Boot sector entry point 0000:7C00
-001000	+------------------------+
-	|  Reserved for MBR/BIOS |
-000800	+------------------------+
-	|  Typically used by MBR |
-000600	+------------------------+ 
-	|  BIOS use only	 |
-000000	+------------------------+
-
-
-When using bzImage, the protected-mode kernel was relocated to
-0x100000 ("high memory"), and the kernel real-mode block (boot sector,
-setup, and stack/heap) was made relocatable to any address between
-0x10000 and end of low memory. Unfortunately, in protocols 2.00 and
-2.01 the 0x90000+ memory range is still used internally by the kernel;
-the 2.02 protocol resolves that problem.
-
-It is desirable to keep the "memory ceiling" -- the highest point in
-low memory touched by the boot loader -- as low as possible, since
-some newer BIOSes have begun to allocate some rather large amounts of
-memory, called the Extended BIOS Data Area, near the top of low
-memory.	 The boot loader should use the "INT 12h" BIOS call to verify
-how much low memory is available.
-
-Unfortunately, if INT 12h reports that the amount of memory is too
-low, there is usually nothing the boot loader can do but to report an
-error to the user.  The boot loader should therefore be designed to
-take up as little space in low memory as it reasonably can.  For
-zImage or old bzImage kernels, which need data written into the
-0x90000 segment, the boot loader should make sure not to use memory
-above the 0x9A000 point; too many BIOSes will break above that point.
-
-For a modern bzImage kernel with boot protocol version >= 2.02, a
-memory layout like the following is suggested:
-
-	~                        ~
-        |  Protected-mode kernel |
-100000  +------------------------+
-	|  I/O memory hole	 |
-0A0000	+------------------------+
-	|  Reserved for BIOS	 |	Leave as much as possible unused
-	~                        ~
-	|  Command line		 |	(Can also be below the X+10000 mark)
-X+10000	+------------------------+
-	|  Stack/heap		 |	For use by the kernel real-mode code.
-X+08000	+------------------------+	
-	|  Kernel setup		 |	The kernel real-mode code.
-	|  Kernel boot sector	 |	The kernel legacy boot sector.
-X       +------------------------+
-	|  Boot loader		 |	<- Boot sector entry point 0000:7C00
-001000	+------------------------+
-	|  Reserved for MBR/BIOS |
-000800	+------------------------+
-	|  Typically used by MBR |
-000600	+------------------------+ 
-	|  BIOS use only	 |
-000000	+------------------------+
-
-... where the address X is as low as the design of the boot loader
-permits.
-
-
-**** THE REAL-MODE KERNEL HEADER
-
-In the following text, and anywhere in the kernel boot sequence, "a
-sector" refers to 512 bytes.  It is independent of the actual sector
-size of the underlying medium.
-
-The first step in loading a Linux kernel should be to load the
-real-mode code (boot sector and setup code) and then examine the
-following header at offset 0x01f1.  The real-mode code can total up to
-32K, although the boot loader may choose to load only the first two
-sectors (1K) and then examine the bootup sector size.
-
-The header looks like:
-
-Offset	Proto	Name		Meaning
-/Size
-
-01F1/1	ALL(1	setup_sects	The size of the setup in sectors
-01F2/2	ALL	root_flags	If set, the root is mounted readonly
-01F4/4	2.04+(2	syssize		The size of the 32-bit code in 16-byte paras
-01F8/2	ALL	ram_size	DO NOT USE - for bootsect.S use only
-01FA/2	ALL	vid_mode	Video mode control

-0214/4	2.00+	code32_start	Boot loader hook (see below)
-0218/4	2.00+	ramdisk_image	initrd load address (set by boot loader)
-021C/4	2.00+	ramdisk_size	initrd size (set by boot loader)
-0220/4	2.00+	bootsect_kludge	DO NOT USE - for bootsect.S use only
-0224/2	2.01+	heap_end_ptr	Free memory after setup end
-0226/1	2.02+(3 ext_loader_ver	Extended boot loader version
-0227/1	2.02+(3	ext_loader_type	Extended boot loader ID
-0228/4	2.02+	cmd_line_ptr	32-bit pointer to the kernel command line

-0235/1	2.10+	min_alignment	Minimum alignment, as a power of two
-0236/2	2.12+	xloadflags	Boot protocol option flags
-0238/4	2.06+	cmdline_size	Maximum size of the kernel command line
-023C/4	2.07+	hardware_subarch Hardware subarchitecture
-0240/8	2.07+	hardware_subarch_data Subarchitecture-specific data
-0248/4	2.08+	payload_offset	Offset of kernel payload

-0260/4	2.10+	init_size	Linear memory required during initialization
-0264/4	2.11+	handover_offset	Offset of handover entry point
-
-(1) For backwards compatibility, if the setup_sects field contains 0, the
-    real value is 4.
-
-(2) For boot protocol prior to 2.04, the upper two bytes of the syssize
-    field are unusable, which means the size of a bzImage kernel
-    cannot be determined.
-
-(3) Ignored, but safe to set, for boot protocols 2.02-2.09.
-
-If the "HdrS" (0x53726448) magic number is not found at offset 0x202,
-the boot protocol version is "old".  Loading an old kernel, the
-following parameters should be assumed:
-
-	Image type = zImage
-	initrd not supported
-	Real-mode kernel must be located at 0x90000.
-
-Otherwise, the "version" field contains the protocol version,
-e.g. protocol version 2.01 will contain 0x0201 in this field.  When
-setting fields in the header, you must make sure only to set fields
-supported by the protocol version in use.
-
-
-**** DETAILS OF HEADER FIELDS
-
-For each field, some are information from the kernel to the bootloader
-("read"), some are expected to be filled out by the bootloader
-("write"), and some are expected to be read and modified by the
-bootloader ("modify").
-
-All general purpose boot loaders should write the fields marked
-(obligatory).  Boot loaders who want to load the kernel at a
-nonstandard address should fill in the fields marked (reloc); other
-boot loaders can ignore those fields.
-
-The byte order of all fields is littleendian (this is x86, after all.)
-
-Field name:	setup_sects
-Type:		read
-Offset/size:	0x1f1/1
-Protocol:	ALL
-
-  The size of the setup code in 512-byte sectors.  If this field is
-  0, the real value is 4.  The real-mode code consists of the boot
-  sector (always one 512-byte sector) plus the setup code.
-
-Field name:	 root_flags
-Type:		 modify (optional)
-Offset/size:	 0x1f2/2
-Protocol:	 ALL
-
-  If this field is nonzero, the root defaults to readonly.  The use of
-  this field is deprecated; use the "ro" or "rw" options on the
-  command line instead.
-
-Field name:	syssize
-Type:		read
-Offset/size:	0x1f4/4 (protocol 2.04+) 0x1f4/2 (protocol ALL)
-Protocol:	2.04+
-
-  The size of the protected-mode code in units of 16-byte paragraphs.
-  For protocol versions older than 2.04 this field is only two bytes
-  wide, and therefore cannot be trusted for the size of a kernel if
-  the LOAD_HIGH flag is set.
-
-Field name:	ram_size
-Type:		kernel internal
-Offset/size:	0x1f8/2
-Protocol:	ALL
-
-  This field is obsolete.
-
-Field name:	vid_mode
-Type:		modify (obligatory)
-Offset/size:	0x1fa/2
-
-  Please see the section on SPECIAL COMMAND LINE OPTIONS.
-
-Field name:	root_dev
-Type:		modify (optional)
-Offset/size:	0x1fc/2
-Protocol:	ALL
-
-  The default root device device number.  The use of this field is
-  deprecated, use the "root=" option on the command line instead.
-
-Field name:	boot_flag
-Type:		read
-Offset/size:	0x1fe/2
-Protocol:	ALL
-
-  Contains 0xAA55.  This is the closest thing old Linux kernels have
-  to a magic number.
-
-Field name:	jump
-Type:		read
-Offset/size:	0x200/2
-Protocol:	2.00+
-
-  Contains an x86 jump instruction, 0xEB followed by a signed offset
-  relative to byte 0x202.  This can be used to determine the size of
-  the header.
-
-Field name:	header
-Type:		read
-Offset/size:	0x202/4
-Protocol:	2.00+
-
-  Contains the magic number "HdrS" (0x53726448).
-
-Field name:	version
-Type:		read
-Offset/size:	0x206/2
-Protocol:	2.00+
-
-  Contains the boot protocol version, in (major << 8)+minor format,
-  e.g. 0x0204 for version 2.04, and 0x0a11 for a hypothetical version
-  10.17.
-
-Field name:	realmode_swtch
-Type:		modify (optional)
-Offset/size:	0x208/4
-Protocol:	2.00+
-
-  Boot loader hook (see ADVANCED BOOT LOADER HOOKS below.)
-
-Field name:	start_sys_seg
-Type:		read
-Offset/size:	0x20c/2
-Protocol:	2.00+
-
-  The load low segment (0x1000).  Obsolete.
-
-Field name:	kernel_version
-Type:		read
-Offset/size:	0x20e/2
-Protocol:	2.00+
-
-  If set to a nonzero value, contains a pointer to a NUL-terminated
-  human-readable kernel version number string, less 0x200.  This can
-  be used to display the kernel version to the user.  This value
-  should be less than (0x200*setup_sects).
-
-  For example, if this value is set to 0x1c00, the kernel version
-  number string can be found at offset 0x1e00 in the kernel file.
-  This is a valid value if and only if the "setup_sects" field
-  contains the value 15 or higher, as:
-
-	0x1c00  < 15*0x200 (= 0x1e00) but
-	0x1c00 >= 14*0x200 (= 0x1c00)
-
-	0x1c00 >> 9 = 14, so the minimum value for setup_secs is 15.
-
-Field name:	type_of_loader
-Type:		write (obligatory)
-Offset/size:	0x210/1
-Protocol:	2.00+
-
-  If your boot loader has an assigned id (see table below), enter
-  0xTV here, where T is an identifier for the boot loader and V is
-  a version number.  Otherwise, enter 0xFF here.
-
-  For boot loader IDs above T = 0xD, write T = 0xE to this field and
-  write the extended ID minus 0x10 to the ext_loader_type field.
-  Similarly, the ext_loader_ver field can be used to provide more than
-  four bits for the bootloader version.
-
-  For example, for T = 0x15, V = 0x234, write:
-
-  type_of_loader  <- 0xE4
-  ext_loader_type <- 0x05
-  ext_loader_ver  <- 0x23
-
-  Assigned boot loader ids (hexadecimal):
-
-	0  LILO			(0x00 reserved for pre-2.00 bootloader)
-	1  Loadlin
-	2  bootsect-loader	(0x20, all other values reserved)
-	3  Syslinux
-	4  Etherboot/gPXE/iPXE

-  value assigned.
-
-Field name:	loadflags
-Type:		modify (obligatory)
-Offset/size:	0x211/1
-Protocol:	2.00+
-
-  This field is a bitmask.
-
-  Bit 0 (read):	LOADED_HIGH
-	- If 0, the protected-mode code is loaded at 0x10000.
-	- If 1, the protected-mode code is loaded at 0x100000.
-
-  Bit 1 (kernel internal): KASLR_FLAG
-	- Used internally by the compressed kernel to communicate
-	  KASLR status to kernel proper.
-	  If 1, KASLR enabled.
-	  If 0, KASLR disabled.
-
-  Bit 5 (write): QUIET_FLAG
-	- If 0, print early messages.
-	- If 1, suppress early messages.
-		This requests to the kernel (decompressor and early
-		kernel) to not write early messages that require
-		accessing the display hardware directly.
-
-  Bit 6 (write): KEEP_SEGMENTS
-	Protocol: 2.07+
-	- If 0, reload the segment registers in the 32bit entry point.
-	- If 1, do not reload the segment registers in the 32bit entry point.
-		Assume that %cs %ds %ss %es are all set to flat segments with
-		a base of 0 (or the equivalent for their environment).
-
-  Bit 7 (write): CAN_USE_HEAP
-	Set this bit to 1 to indicate that the value entered in the
-	heap_end_ptr is valid.  If this field is clear, some setup code
-	functionality will be disabled.
-
-Field name:	setup_move_size
-Type:		modify (obligatory)
-Offset/size:	0x212/2
-Protocol:	2.00-2.01
-
-  When using protocol 2.00 or 2.01, if the real mode kernel is not
-  loaded at 0x90000, it gets moved there later in the loading
-  sequence.  Fill in this field if you want additional data (such as
-  the kernel command line) moved in addition to the real-mode kernel
-  itself.
-
-  The unit is bytes starting with the beginning of the boot sector.
-  
-  This field is can be ignored when the protocol is 2.02 or higher, or
-  if the real-mode code is loaded at 0x90000.
-
-Field name:	code32_start
-Type:		modify (optional, reloc)
-Offset/size:	0x214/4
-Protocol:	2.00+
-
-  The address to jump to in protected mode.  This defaults to the load
-  address of the kernel, and can be used by the boot loader to
-  determine the proper load address.
-
-  This field can be modified for two purposes:
-
-  1. as a boot loader hook (see ADVANCED BOOT LOADER HOOKS below.)
-
-  2. if a bootloader which does not install a hook loads a
-     relocatable kernel at a nonstandard address it will have to modify
-     this field to point to the load address.
-
-Field name:	ramdisk_image
-Type:		write (obligatory)
-Offset/size:	0x218/4
-Protocol:	2.00+
-
-  The 32-bit linear address of the initial ramdisk or ramfs.  Leave at
-  zero if there is no initial ramdisk/ramfs.
-
-Field name:	ramdisk_size
-Type:		write (obligatory)
-Offset/size:	0x21c/4
-Protocol:	2.00+
-
-  Size of the initial ramdisk or ramfs.  Leave at zero if there is no
-  initial ramdisk/ramfs.
-
-Field name:	bootsect_kludge
-Type:		kernel internal
-Offset/size:	0x220/4
-Protocol:	2.00+
-
-  This field is obsolete.
-
-Field name:	heap_end_ptr
-Type:		write (obligatory)
-Offset/size:	0x224/2
-Protocol:	2.01+
-
-  Set this field to the offset (from the beginning of the real-mode
-  code) of the end of the setup stack/heap, minus 0x0200.
-
-Field name:	ext_loader_ver
-Type:		write (optional)
-Offset/size:	0x226/1
-Protocol:	2.02+
-
-  This field is used as an extension of the version number in the
-  type_of_loader field.  The total version number is considered to be
-  (type_of_loader & 0x0f) + (ext_loader_ver << 4).
-
-  The use of this field is boot loader specific.  If not written, it
-  is zero.
-
-  Kernels prior to 2.6.31 did not recognize this field, but it is safe
-  to write for protocol version 2.02 or higher.
-
-Field name:	ext_loader_type
-Type:		write (obligatory if (type_of_loader & 0xf0) == 0xe0)
-Offset/size:	0x227/1
-Protocol:	2.02+
-
-  This field is used as an extension of the type number in
-  type_of_loader field.  If the type in type_of_loader is 0xE, then
-  the actual type is (ext_loader_type + 0x10).
-
-  This field is ignored if the type in type_of_loader is not 0xE.
-
-  Kernels prior to 2.6.31 did not recognize this field, but it is safe
-  to write for protocol version 2.02 or higher.
-
-Field name:	cmd_line_ptr
-Type:		write (obligatory)
-Offset/size:	0x228/4
-Protocol:	2.02+
-
-  Set this field to the linear address of the kernel command line.
-  The kernel command line can be located anywhere between the end of
-  the setup heap and 0xA0000; it does not have to be located in the
-  same 64K segment as the real-mode code itself.
-
-  Fill in this field even if your boot loader does not support a
-  command line, in which case you can point this to an empty string
-  (or better yet, to the string "auto".)  If this field is left at
-  zero, the kernel will assume that your boot loader does not support
-  the 2.02+ protocol.
-
-Field name:	initrd_addr_max
-Type:		read
-Offset/size:	0x22c/4
-Protocol:	2.03+
-
-  The maximum address that may be occupied by the initial
-  ramdisk/ramfs contents.  For boot protocols 2.02 or earlier, this
-  field is not present, and the maximum address is 0x37FFFFFF.  (This
-  address is defined as the address of the highest safe byte, so if
-  your ramdisk is exactly 131072 bytes long and this field is
-  0x37FFFFFF, you can start your ramdisk at 0x37FE0000.)
-
-Field name:	kernel_alignment
-Type:		read/modify (reloc)
-Offset/size:	0x230/4
-Protocol:	2.05+ (read), 2.10+ (modify)
-
-  Alignment unit required by the kernel (if relocatable_kernel is
-  true.)  A relocatable kernel that is loaded at an alignment
-  incompatible with the value in this field will be realigned during
-  kernel initialization.
-
-  Starting with protocol version 2.10, this reflects the kernel
-  alignment preferred for optimal performance; it is possible for the
-  loader to modify this field to permit a lesser alignment.  See the
-  min_alignment and pref_address field below.
-
-Field name:	relocatable_kernel
-Type:		read (reloc)
-Offset/size:	0x234/1
-Protocol:	2.05+
-
-  If this field is nonzero, the protected-mode part of the kernel can
-  be loaded at any address that satisfies the kernel_alignment field.
-  After loading, the boot loader must set the code32_start field to
-  point to the loaded code, or to a boot loader hook.
-
-Field name:	min_alignment
-Type:		read (reloc)
-Offset/size:	0x235/1
-Protocol:	2.10+
-
-  This field, if nonzero, indicates as a power of two the minimum
-  alignment required, as opposed to preferred, by the kernel to boot.
-  If a boot loader makes use of this field, it should update the
-  kernel_alignment field with the alignment unit desired; typically:
-
-	kernel_alignment = 1 << min_alignment
-
-  There may be a considerable performance cost with an excessively
-  misaligned kernel.  Therefore, a loader should typically try each
-  power-of-two alignment from kernel_alignment down to this alignment.
-
-Field name:     xloadflags
-Type:           read
-Offset/size:    0x236/2
-Protocol:       2.12+
-
-  This field is a bitmask.
-
-  Bit 0 (read):	XLF_KERNEL_64
-	- If 1, this kernel has the legacy 64-bit entry point at 0x200.
-
-  Bit 1 (read): XLF_CAN_BE_LOADED_ABOVE_4G
-        - If 1, kernel/boot_params/cmdline/ramdisk can be above 4G.
-
-  Bit 2 (read):	XLF_EFI_HANDOVER_32
-	- If 1, the kernel supports the 32-bit EFI handoff entry point
-          given at handover_offset.
-
-  Bit 3 (read): XLF_EFI_HANDOVER_64
-	- If 1, the kernel supports the 64-bit EFI handoff entry point
-          given at handover_offset + 0x200.
-
-  Bit 4 (read): XLF_EFI_KEXEC
-	- If 1, the kernel supports kexec EFI boot with EFI runtime support.
-
-Field name:	cmdline_size
-Type:		read
-Offset/size:	0x238/4
-Protocol:	2.06+
-
-  The maximum size of the command line without the terminating
-  zero. This means that the command line can contain at most
-  cmdline_size characters. With protocol version 2.05 and earlier, the
-  maximum size was 255.
-
-Field name:	hardware_subarch
-Type:		write (optional, defaults to x86/PC)
-Offset/size:	0x23c/4
-Protocol:	2.07+
-
-  In a paravirtualized environment the hardware low level architectural
-  pieces such as interrupt handling, page table handling, and
-  accessing process control registers needs to be done differently.
-
-  This field allows the bootloader to inform the kernel we are in one
-  one of those environments.
-
-  0x00000000	The default x86/PC environment
-  0x00000001	lguest
-  0x00000002	Xen
-  0x00000003	Moorestown MID
-  0x00000004	CE4100 TV Platform
-
-Field name:	hardware_subarch_data
-Type:		write (subarch-dependent)
-Offset/size:	0x240/8
-Protocol:	2.07+
-
-  A pointer to data that is specific to hardware subarch
-  This field is currently unused for the default x86/PC environment,
-  do not modify.
-
-Field name:	payload_offset
-Type:		read
-Offset/size:	0x248/4
-Protocol:	2.08+
-
-  If non-zero then this field contains the offset from the beginning
-  of the protected-mode code to the payload.
-
-  The payload may be compressed. The format of both the compressed and
-  uncompressed data should be determined using the standard magic
-  numbers.  The currently supported compression formats are gzip
-  (magic numbers 1F 8B or 1F 9E), bzip2 (magic number 42 5A), LZMA
-  (magic number 5D 00), XZ (magic number FD 37), and LZ4 (magic number
-  02 21).  The uncompressed payload is currently always ELF (magic
-  number 7F 45 4C 46).
-
-Field name:	payload_length
-Type:		read
-Offset/size:	0x24c/4
-Protocol:	2.08+
-
-  The length of the payload.
-
-Field name:	setup_data
-Type:		write (special)
-Offset/size:	0x250/8
-Protocol:	2.09+
-
-  The 64-bit physical pointer to NULL terminated single linked list of
-  struct setup_data. This is used to define a more extensible boot
-  parameters passing mechanism. The definition of struct setup_data is
-  as follow:
-
-  struct setup_data {
-	  u64 next;
-	  u32 type;
-	  u32 len;
-	  u8  data[0];
-  };
-
-  Where, the next is a 64-bit physical pointer to the next node of
-  linked list, the next field of the last node is 0; the type is used
-  to identify the contents of data; the len is the length of data
-  field; the data holds the real payload.
-
-  This list may be modified at a number of points during the bootup
-  process.  Therefore, when modifying this list one should always make
-  sure to consider the case where the linked list already contains
-  entries.
-
-Field name:	pref_address
-Type:		read (reloc)
-Offset/size:	0x258/8
-Protocol:	2.10+
-
-  This field, if nonzero, represents a preferred load address for the
-  kernel.  A relocating bootloader should attempt to load at this
-  address if possible.
-
-  A non-relocatable kernel will unconditionally move itself and to run
-  at this address.
-
-Field name:	init_size
-Type:		read
-Offset/size:	0x260/4
-
-  This field indicates the amount of linear contiguous memory starting
-  at the kernel runtime start address that the kernel needs before it
-  is capable of examining its memory map.  This is not the same thing
-  as the total amount of memory the kernel needs to boot, but it can
-  be used by a relocating boot loader to help select a safe load
-  address for the kernel.
-
-  The kernel runtime start address is determined by the following algorithm:
-
-  if (relocatable_kernel)
-	runtime_start = align_up(load_address, kernel_alignment)
-  else
-	runtime_start = pref_address
-
-Field name:	handover_offset
-Type:		read
-Offset/size:	0x264/4
-
-  This field is the offset from the beginning of the kernel image to
-  the EFI handover protocol entry point. Boot loaders using the EFI
-  handover protocol to boot the kernel should jump to this offset.
-
-  See EFI HANDOVER PROTOCOL below for more details.
-
-
-**** THE IMAGE CHECKSUM
-
-From boot protocol version 2.08 onwards the CRC-32 is calculated over
-the entire file using the characteristic polynomial 0x04C11DB7 and an
-initial remainder of 0xffffffff.  The checksum is appended to the
-file; therefore the CRC of the file up to the limit specified in the
-syssize field of the header is always 0.
-
-
-**** THE KERNEL COMMAND LINE
-
-The kernel command line has become an important way for the boot
-loader to communicate with the kernel.  Some of its options are also
-relevant to the boot loader itself, see "special command line options"
-below.
-
-The kernel command line is a null-terminated string. The maximum
-length can be retrieved from the field cmdline_size.  Before protocol
-version 2.06, the maximum was 255 characters.  A string that is too
-long will be automatically truncated by the kernel.
-
-If the boot protocol version is 2.02 or later, the address of the
-kernel command line is given by the header field cmd_line_ptr (see
-above.)  This address can be anywhere between the end of the setup
-heap and 0xA0000.
-
-If the protocol version is *not* 2.02 or higher, the kernel
-command line is entered using the following protocol:
-
-	At offset 0x0020 (word), "cmd_line_magic", enter the magic
-	number 0xA33F.
-
-	At offset 0x0022 (word), "cmd_line_offset", enter the offset
-	of the kernel command line (relative to the start of the
-	real-mode kernel).
-	
-	The kernel command line *must* be within the memory region
-	covered by setup_move_size, so you may need to adjust this
-	field.
-
-
-**** MEMORY LAYOUT OF THE REAL-MODE CODE
-
-The real-mode code requires a stack/heap to be set up, as well as
-memory allocated for the kernel command line.  This needs to be done
-in the real-mode accessible memory in bottom megabyte.
-
-It should be noted that modern machines often have a sizable Extended
-BIOS Data Area (EBDA).  As a result, it is advisable to use as little
-of the low megabyte as possible.
-
-Unfortunately, under the following circumstances the 0x90000 memory
-segment has to be used:
-
-	- When loading a zImage kernel ((loadflags & 0x01) == 0).
-	- When loading a 2.01 or earlier boot protocol kernel.
-
-	  -> For the 2.00 and 2.01 boot protocols, the real-mode code
-	     can be loaded at another address, but it is internally
-	     relocated to 0x90000.  For the "old" protocol, the
-	     real-mode code must be loaded at 0x90000.
-
-When loading at 0x90000, avoid using memory above 0x9a000.
-
-For boot protocol 2.02 or higher, the command line does not have to be
-located in the same 64K segment as the real-mode setup code; it is
-thus permitted to give the stack/heap the full 64K segment and locate
-the command line above it.
-
-The kernel command line should not be located below the real-mode
-code, nor should it be located in high memory.
-
-
-**** SAMPLE BOOT CONFIGURATION
-
-As a sample configuration, assume the following layout of the real
-mode segment:
-
-    When loading below 0x90000, use the entire segment:
-
-	0x0000-0x7fff	Real mode kernel
-	0x8000-0xdfff	Stack and heap
-	0xe000-0xffff	Kernel command line
-
-    When loading at 0x90000 OR the protocol version is 2.01 or earlier:
-
-	0x0000-0x7fff	Real mode kernel
-	0x8000-0x97ff	Stack and heap
-	0x9800-0x9fff	Kernel command line
-
-Such a boot loader should enter the following fields in the header:
-
-	unsigned long base_ptr;	/* base address for real-mode segment */
-
-	if ( setup_sects == 0 ) {
-		setup_sects = 4;
-	}
-
-	if ( protocol >= 0x0200 ) {
-		type_of_loader = <type code>;
-		if ( loading_initrd ) {
-			ramdisk_image = <initrd_address>;
-			ramdisk_size = <initrd_size>;
-		}
-
-		if ( protocol >= 0x0202 && loadflags & 0x01 )
-			heap_end = 0xe000;
-		else
-			heap_end = 0x9800;
-
-		if ( protocol >= 0x0201 ) {
-			heap_end_ptr = heap_end - 0x200;
-			loadflags |= 0x80; /* CAN_USE_HEAP */
-		}
-
-		if ( protocol >= 0x0202 ) {
-			cmd_line_ptr = base_ptr + heap_end;
-			strcpy(cmd_line_ptr, cmdline);
-		} else {
-			cmd_line_magic	= 0xA33F;
-			cmd_line_offset = heap_end;
-			setup_move_size = heap_end + strlen(cmdline)+1;
-			strcpy(base_ptr+cmd_line_offset, cmdline);
-		}
-	} else {
-		/* Very old kernel */
-
-		heap_end = 0x9800;
-
-		cmd_line_magic	= 0xA33F;
-		cmd_line_offset = heap_end;
-
-		/* A very old kernel MUST have its real-mode code
-		   loaded at 0x90000 */
-
-		if ( base_ptr != 0x90000 ) {
-			/* Copy the real-mode kernel */
-			memcpy(0x90000, base_ptr, (setup_sects+1)*512);
-			base_ptr = 0x90000;		 /* Relocated */
-		}
-
-		strcpy(0x90000+cmd_line_offset, cmdline);
-
-		/* It is recommended to clear memory up to the 32K mark */
-		memset(0x90000 + (setup_sects+1)*512, 0,
-		       (64-(setup_sects+1))*512);
-	}
-
-
-**** LOADING THE REST OF THE KERNEL
-
-The 32-bit (non-real-mode) kernel starts at offset (setup_sects+1)*512
-in the kernel file (again, if setup_sects == 0 the real value is 4.)
-It should be loaded at address 0x10000 for Image/zImage kernels and
-0x100000 for bzImage kernels.
-
-The kernel is a bzImage kernel if the protocol >= 2.00 and the 0x01
-bit (LOAD_HIGH) in the loadflags field is set:
-
-	is_bzImage = (protocol >= 0x0200) && (loadflags & 0x01);
-	load_address = is_bzImage ? 0x100000 : 0x10000;
-
-Note that Image/zImage kernels can be up to 512K in size, and thus use
-the entire 0x10000-0x90000 range of memory.  This means it is pretty
-much a requirement for these kernels to load the real-mode part at
-0x90000.  bzImage kernels allow much more flexibility.
-
-
-**** SPECIAL COMMAND LINE OPTIONS
-
-If the command line provided by the boot loader is entered by the
-user, the user may expect the following command line options to work.
-They should normally not be deleted from the kernel command line even
-though not all of them are actually meaningful to the kernel.  Boot
-loader authors who need additional command line options for the boot
-loader itself should get them registered in
-Documentation/admin-guide/kernel-parameters.rst to make sure they will not
-conflict with actual kernel options now or in the future.
-
-  vga=<mode>
-	<mode> here is either an integer (in C notation, either
-	decimal, octal, or hexadecimal) or one of the strings
-	"normal" (meaning 0xFFFF), "ext" (meaning 0xFFFE) or "ask"
-	(meaning 0xFFFD).  This value should be entered into the
-	vid_mode field, as it is used by the kernel before the command
-	line is parsed.
-
-  mem=<size>
-	<size> is an integer in C notation optionally followed by
-	(case insensitive) K, M, G, T, P or E (meaning << 10, << 20,
-	<< 30, << 40, << 50 or << 60).  This specifies the end of
-	memory to the kernel. This affects the possible placement of
-	an initrd, since an initrd should be placed near end of
-	memory.  Note that this is an option to *both* the kernel and
-	the bootloader!
-
-  initrd=<file>
-	An initrd should be loaded.  The meaning of <file> is
-	obviously bootloader-dependent, and some boot loaders
-	(e.g. LILO) do not have such a command.
-
-In addition, some boot loaders add the following options to the
-user-specified command line:
-
-  BOOT_IMAGE=<file>
-	The boot image which was loaded.  Again, the meaning of <file>
-	is obviously bootloader-dependent.
-
-  auto
-	The kernel was booted without explicit user intervention.
-
-If these options are added by the boot loader, it is highly
-recommended that they are located *first*, before the user-specified
-or configuration-specified command line.  Otherwise, "init=/bin/sh"
-gets confused by the "auto" option.
-
-
-**** RUNNING THE KERNEL
-
-The kernel is started by jumping to the kernel entry point, which is
-located at *segment* offset 0x20 from the start of the real mode
-kernel.  This means that if you loaded your real-mode kernel code at
-0x90000, the kernel entry point is 9020:0000.
-
-At entry, ds = es = ss should point to the start of the real-mode
-kernel code (0x9000 if the code is loaded at 0x90000), sp should be
-set up properly, normally pointing to the top of the heap, and
-interrupts should be disabled.  Furthermore, to guard against bugs in
-the kernel, it is recommended that the boot loader sets fs = gs = ds =
-es = ss.
-
-In our example from above, we would do:
-
-	/* Note: in the case of the "old" kernel protocol, base_ptr must
-	   be == 0x90000 at this point; see the previous sample code */
-
-	seg = base_ptr >> 4;
-
-	cli();	/* Enter with interrupts disabled! */
-
-	/* Set up the real-mode kernel stack */
-	_SS = seg;
-	_SP = heap_end;
-
-	_DS = _ES = _FS = _GS = seg;
-	jmp_far(seg+0x20, 0);	/* Run the kernel */
-
-If your boot sector accesses a floppy drive, it is recommended to
-switch off the floppy motor before running the kernel, since the
-kernel boot leaves interrupts off and thus the motor will not be
-switched off, especially if the loaded kernel has the floppy driver as
-a demand-loaded module!
-
-
-**** ADVANCED BOOT LOADER HOOKS
-
-If the boot loader runs in a particularly hostile environment (such as
-LOADLIN, which runs under DOS) it may be impossible to follow the
-standard memory location requirements.  Such a boot loader may use the
-following hooks that, if set, are invoked by the kernel at the
-appropriate time.  The use of these hooks should probably be
-considered an absolutely last resort!
-
-IMPORTANT: All the hooks are required to preserve %esp, %ebp, %esi and
-%edi across invocation.
-
-  realmode_swtch:
-	A 16-bit real mode far subroutine invoked immediately before
-	entering protected mode.  The default routine disables NMI, so
-	your routine should probably do so, too.
-
-  code32_start:
-	A 32-bit flat-mode routine *jumped* to immediately after the
-	transition to protected mode, but before the kernel is
-	uncompressed.  No segments, except CS, are guaranteed to be
-	set up (current kernels do, but older ones do not); you should
-	set them up to BOOT_DS (0x18) yourself.
-
-	After completing your hook, you should jump to the address
-	that was in this field before your boot loader overwrote it
-	(relocated, if appropriate.)
-
-
-**** 32-bit BOOT PROTOCOL
-
-For machine with some new BIOS other than legacy BIOS, such as EFI,
-LinuxBIOS, etc, and kexec, the 16-bit real mode setup code in kernel
-based on legacy BIOS can not be used, so a 32-bit boot protocol needs
-to be defined.
-
-In 32-bit boot protocol, the first step in loading a Linux kernel
-should be to setup the boot parameters (struct boot_params,
-traditionally known as "zero page"). The memory for struct boot_params
-should be allocated and initialized to all zero. Then the setup header
-from offset 0x01f1 of kernel image on should be loaded into struct
-boot_params and examined. The end of setup header can be calculated as
-follow:
-
-	0x0202 + byte value at offset 0x0201
-
-In addition to read/modify/write the setup header of the struct
-boot_params as that of 16-bit boot protocol, the boot loader should
-also fill the additional fields of the struct boot_params as that
-described in zero-page.txt.
-
-After setting up the struct boot_params, the boot loader can load the
-32/64-bit kernel in the same way as that of 16-bit boot protocol.
-
-In 32-bit boot protocol, the kernel is started by jumping to the
-32-bit kernel entry point, which is the start address of loaded
-32/64-bit kernel.
-
-At entry, the CPU must be in 32-bit protected mode with paging
-disabled; a GDT must be loaded with the descriptors for selectors
-__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat
-segment; __BOOT_CS must have execute/read permission, and __BOOT_DS
-must have read/write permission; CS must be __BOOT_CS and DS, ES, SS
-must be __BOOT_DS; interrupt must be disabled; %esi must hold the base
-address of the struct boot_params; %ebp, %edi and %ebx must be zero.
-
-**** 64-bit BOOT PROTOCOL
-
-For machine with 64bit cpus and 64bit kernel, we could use 64bit bootloader
-and we need a 64-bit boot protocol.
-
-In 64-bit boot protocol, the first step in loading a Linux kernel
-should be to setup the boot parameters (struct boot_params,
-traditionally known as "zero page"). The memory for struct boot_params
-could be allocated anywhere (even above 4G) and initialized to all zero.
-Then, the setup header at offset 0x01f1 of kernel image on should be
-loaded into struct boot_params and examined. The end of setup header
-can be calculated as follows:
-
-	0x0202 + byte value at offset 0x0201
-
-In addition to read/modify/write the setup header of the struct
-boot_params as that of 16-bit boot protocol, the boot loader should
-also fill the additional fields of the struct boot_params as described
-in zero-page.txt.
-
-After setting up the struct boot_params, the boot loader can load
-64-bit kernel in the same way as that of 16-bit boot protocol, but
-kernel could be loaded above 4G.
-
-In 64-bit boot protocol, the kernel is started by jumping to the
-64-bit kernel entry point, which is the start address of loaded
-64-bit kernel plus 0x200.
-
-At entry, the CPU must be in 64-bit mode with paging enabled.
-The range with setup_header.init_size from start address of loaded
-kernel and zero page and command line buffer get ident mapping;
-a GDT must be loaded with the descriptors for selectors
-__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat
-segment; __BOOT_CS must have execute/read permission, and __BOOT_DS
-must have read/write permission; CS must be __BOOT_CS and DS, ES, SS
-must be __BOOT_DS; interrupt must be disabled; %rsi must hold the base
-address of the struct boot_params.
-
-**** EFI HANDOVER PROTOCOL
-
-This protocol allows boot loaders to defer initialisation to the EFI
-boot stub. The boot loader is required to load the kernel/initrd(s)
-from the boot media and jump to the EFI handover protocol entry point
-which is hdr->handover_offset bytes from the beginning of
-startup_{32,64}.
-
-The function prototype for the handover entry point looks like this,
-
-    efi_main(void *handle, efi_system_table_t *table, struct boot_params *bp)
-
-'handle' is the EFI image handle passed to the boot loader by the EFI
-firmware, 'table' is the EFI system table - these are the first two
-arguments of the "handoff state" as described in section 2.3 of the
-UEFI specification. 'bp' is the boot loader-allocated boot params.
-
-The boot loader *must* fill out the following fields in bp,
-
-    o hdr.code32_start
-    o hdr.cmd_line_ptr
-    o hdr.ramdisk_image (if applicable)
-    o hdr.ramdisk_size  (if applicable)
-
-All other fields should be zero.

+
+  d) The NetChip device must be plugged directly into the physical
+     debug port on the "host/target" system. You cannot use a USB hub in
+     between the physical debug port and the "host/target" system.

+     The EHCI debug controller is bound to a specific physical USB
+     port and the NetChip device will only work as an early printk
+     device in this port.  The EHCI host controllers are electrically
+     wired such that the EHCI debug controller is hooked up to the
+     first physical port and there is no way to change this via software.
+     You can find the physical port through experimentation by trying
+     each physical port on the system and rebooting.  Or you can try
+     and use lsusb or look at the kernel info messages emitted by the
+     usb stack when you plug a usb device into various ports on the
+     "host/target" system.
+
+     Some hardware vendors do not expose the usb debug port with a
+     physical connector and if you find such a device send a complaint
+     to the hardware vendor, because there is no reason not to wire
+     this port into one of the physically accessible ports.
+
+  e) It is also important to note, that many versions of the NetChip
+     device require the "client/console" system to be plugged into the
+     right hand side of the device (with the product logo facing up and
+     readable left to right).  The reason being is that the 5 volt
+     power supply is taken from only one side of the device and it
+     must be the side that does not get rebooted.
+
+Software requirements
+=====================
+
+  a) On the host/target system:
+
+    You need to enable the following kernel config option::
+
+      CONFIG_EARLY_PRINTK_DBGP=y
+
+    And you need to add the boot command line: "earlyprintk=dbgp".
+
+    .. note::
+      If you are using Grub, append it to the 'kernel' line in
+      /etc/grub.conf.  If you are using Grub2 on a BIOS firmware system,
+      append it to the 'linux' line in /boot/grub2/grub.cfg. If you are
+      using Grub2 on an EFI firmware system, append it to the 'linux'
+      or 'linuxefi' line in /boot/grub2/grub.cfg or
+      /boot/efi/EFI/<distro>/grub.cfg.
+
+    On systems with more than one EHCI debug controller you must
+    specify the correct EHCI debug controller number.  The ordering
+    comes from the PCI bus enumeration of the EHCI controllers.  The
+    default with no number argument is "0" or the first EHCI debug
+    controller.  To use the second EHCI debug controller, you would
+    use the command line: "earlyprintk=dbgp1"
+
+    .. note::
+      normally earlyprintk console gets turned off once the
+      regular console is alive - use "earlyprintk=dbgp,keep" to keep
+      this channel open beyond early bootup. This can be useful for
+      debugging crashes under Xorg, etc.
+
+  b) On the client/console system:
+
+    You should enable the following kernel config option::
+
+      CONFIG_USB_SERIAL_DEBUG=y
+
+    On the next bootup with the modified kernel you should
+    get a /dev/ttyUSBx device(s).
+
+    Now this channel of kernel messages is ready to be used: start
+    your favorite terminal emulator (minicom, etc.) and set
+    it up to use /dev/ttyUSB0 - or use a raw 'cat /dev/ttyUSBx' to
+    see the raw output.
+
+  c) On Nvidia Southbridge based systems: the kernel will try to probe
+     and find out which port has a debug device connected.
+
+Testing
+=======
+
+You can test the output by using earlyprintk=dbgp,keep and provoking
+kernel messages on the host/target system. You can provoke a harmless
+kernel message by for example doing::
+
+     echo h > /proc/sysrq-trigger
+
+On the host/target system you should see this help line in "dmesg" output::
+
+     SysRq : HELP : loglevel(0-9) reBoot Crashdump terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) saK show-backtrace-all-active-cpus(L) show-memory-usage(M) nice-all-RT-tasks(N) powerOff show-registers(P) show-all-timers(Q) unRaw Sync show-task-states(T) Unmount show-blocked-tasks(W) dump-ftrace-buffer(Z)
+
+On the client/console system do::
+
+       cat /dev/ttyUSB0
+
+And you should see the help line above displayed shortly after you've
+provoked it on the host system.
+
+If it does not work then please ask about it on the linux-kernel@vger.kernel.org
+mailing list or contact the x86 maintainers.

-
-You need two computers, the 'USB debug key' special gadget and
-and two USB cables, connected like this:
-
-  [host/target] <-------> [USB debug key] <-------> [client/console]
-
-1. There are a number of specific hardware requirements:
-
- a.) Host/target system needs to have USB debug port capability.
-
- You can check this capability by looking at a 'Debug port' bit in
- the lspci -vvv output:
-

-( If your system does not list a debug port capability then you probably
-  won't be able to use the USB debug key. )
-
- b.) You also need a NetChip USB debug cable/key:
-
-        http://www.plxtech.com/products/NET2000/NET20DC/default.asp
-
-     This is a small blue plastic connector with two USB connections;
-     it draws power from its USB connections.
-
- c.) You need a second client/console system with a high speed USB 2.0
-     port.
-
- d.) The NetChip device must be plugged directly into the physical
-     debug port on the "host/target" system.  You cannot use a USB hub in
-     between the physical debug port and the "host/target" system.

+Kernel Entries
+==============
+
+This file documents some of the kernel entries in
+arch/x86/entry/entry_64.S.  A lot of this explanation is adapted from
+an email from Ingo Molnar:
+
+http://lkml.kernel.org/r/<20110529191055.GC9835%40elte.hu>
+
+The x86 architecture has quite a few different ways to jump into
+kernel code.  Most of these entry points are registered in
+arch/x86/kernel/traps.c and implemented in arch/x86/entry/entry_64.S
+for 64-bit, arch/x86/entry/entry_32.S for 32-bit and finally
+arch/x86/entry/entry_64_compat.S which implements the 32-bit compatibility
+syscall entry points and thus provides for 32-bit processes the
+ability to execute syscalls when running on 64-bit kernels.
+
+The IDT vector assignments are listed in arch/x86/include/asm/irq_vectors.h.
+
+Some of these entries are:
+
+ - system_call: syscall instruction from 64-bit code.
+
+ - entry_INT80_compat: int 0x80 from 32-bit or 64-bit code; compat syscall
+   either way.
+
+ - entry_INT80_compat, ia32_sysenter: syscall and sysenter from 32-bit
+   code
+
+ - interrupt: An array of entries.  Every IDT vector that doesn't
+   explicitly point somewhere else gets set to the corresponding
+   value in interrupts.  These point to a whole array of
+   magically-generated functions that make their way to do_IRQ with
+   the interrupt number as a parameter.
+
+ - APIC interrupts: Various special-purpose interrupts for things
+   like TLB shootdown.
+
+ - Architecturally-defined exceptions like divide_error.
+
+There are a few complexities here.  The different x86-64 entries
+have different calling conventions.  The syscall and sysenter
+instructions have their own peculiar calling conventions.  Some of
+the IDT entries push an error code onto the stack; others don't.
+IDT entries using the IST alternative stack mechanism need their own
+magic to get the stack frames right.  (You can find some
+documentation in the AMD APM, Volume 2, Chapter 8 and the Intel SDM,
+Volume 3, Chapter 6.)
+
+Dealing with the swapgs instruction is especially tricky.  Swapgs
+toggles whether gs is the kernel gs or the user gs.  The swapgs
+instruction is rather fragile: it must nest perfectly and only in
+single depth, it should only be used if entering from user mode to
+kernel mode and then when returning to user-space, and precisely
+so. If we mess that up even slightly, we crash.
+
+So when we have a secondary entry, already in kernel mode, we *must
+not* use SWAPGS blindly - nor must we forget doing a SWAPGS when it's
+not switched/swapped yet.
+
+Now, there's a secondary complication: there's a cheap way to test
+which mode the CPU is in and an expensive way.
+
+The cheap way is to pick this info off the entry frame on the kernel
+stack, from the CS of the ptregs area of the kernel stack::
+
+	xorl %ebx,%ebx
+	testl $3,CS+8(%rsp)
+	je error_kernelspace
+	SWAPGS
+
+The expensive (paranoid) way is to read back the MSR_GS_BASE value
+(which is what SWAPGS modifies)::
+
+	movl $1,%ebx
+	movl $MSR_GS_BASE,%ecx
+	rdmsr
+	testl %edx,%edx
+	js 1f   /* negative -> in kernel */
+	SWAPGS
+	xorl %ebx,%ebx
+  1:	ret
+
+If we are at an interrupt or user-trap/gate-alike boundary then we can
+use the faster check: the stack will be a reliable indicator of
+whether SWAPGS was already done: if we see that we are a secondary
+entry interrupting kernel mode execution, then we know that the GS
+base has already been switched. If it says that we interrupted
+user-space execution then we must do the SWAPGS.
+
+But if we are in an NMI/MCE/DEBUG/whatever super-atomic entry context,
+which might have triggered right after a normal entry wrote CS to the
+stack but before we executed SWAPGS, then the only safe way to check
+for GS is the slower method: the RDMSR.
+
+Therefore, super-atomic entries (except NMI, which is handled separately)
+must use idtentry with paranoid=1 to handle gsbase correctly.  This
+triggers three main behavior changes:
+
+ - Interrupt entry will use the slower gsbase check.
+ - Interrupt entry from user mode will switch off the IST stack.
+ - Interrupt exit to kernel mode will not attempt to reschedule.
+
+We try to only use IST entries and the paranoid entry code for vectors
+that absolutely need the more expensive check for the GS base - and we
+generate all 'normal' entry points with the regular (faster) paranoid=0
+variant.

+===============================
+Kernel level exception handling
+===============================
+
+Commentary by Joerg Pommnitz <joerg@raleigh.ibm.com>
+
+When a process runs in kernel mode, it often has to access user
+mode memory whose address has been passed by an untrusted program.
+To protect itself the kernel has to verify this address.
+
+In older versions of Linux this was done with the
+int verify_area(int type, const void * addr, unsigned long size)
+function (which has since been replaced by access_ok()).
+
+This function verified that the memory area starting at address
+'addr' and of size 'size' was accessible for the operation specified
+in type (read or write). To do this, verify_read had to look up the
+virtual memory area (vma) that contained the address addr. In the
+normal case (correctly working program), this test was successful.
+It only failed for a few buggy programs. In some kernel profiling
+tests, this normally unneeded verification used up a considerable
+amount of time.
+
+To overcome this situation, Linus decided to let the virtual memory
+hardware present in every Linux-capable CPU handle this test.
+
+How does this work?
+
+Whenever the kernel tries to access an address that is currently not
+accessible, the CPU generates a page fault exception and calls the
+page fault handler::
+
+  void do_page_fault(struct pt_regs *regs, unsigned long error_code)
+
+in arch/x86/mm/fault.c. The parameters on the stack are set up by
+the low level assembly glue in arch/x86/kernel/entry_32.S. The parameter
+regs is a pointer to the saved registers on the stack, error_code
+contains a reason code for the exception.
+
+do_page_fault first obtains the unaccessible address from the CPU
+control register CR2. If the address is within the virtual address
+space of the process, the fault probably occurred, because the page
+was not swapped in, write protected or something similar. However,
+we are interested in the other case: the address is not valid, there
+is no vma that contains this address. In this case, the kernel jumps
+to the bad_area label.
+
+There it uses the address of the instruction that caused the exception
+(i.e. regs->eip) to find an address where the execution can continue
+(fixup). If this search is successful, the fault handler modifies the
+return address (again regs->eip) and returns. The execution will
+continue at the address in fixup.
+
+Where does fixup point to?
+
+Since we jump to the contents of fixup, fixup obviously points
+to executable code. This code is hidden inside the user access macros.
+I have picked the get_user macro defined in arch/x86/include/asm/uaccess.h
+as an example. The definition is somewhat hard to follow, so let's peek at
+the code generated by the preprocessor and the compiler. I selected

+
+The optimizer does a good job and gives us something we can actually
+understand. Can we? The actual user access is quite obvious. Thanks
+to the unified address space we can just access the address in user
+memory. But what does the .section stuff do?????
+
+To understand this we have to look at the final kernel::

+
+There are obviously 2 non standard ELF sections in the generated object
+file. But first we want to find out what happened to our code in the
+final kernel executable::
+
+ > objdump --disassemble --section=.text vmlinux
+ >
+ > c017e785 <do_con_write+c1> xorl   %edx,%edx
+ > c017e787 <do_con_write+c3> movl   0xc01c7bec,%eax
+ > c017e78c <do_con_write+c8> cmpl   $0x18,0x314(%eax)
+ > c017e793 <do_con_write+cf> je     c017e79f <do_con_write+db>
+ > c017e795 <do_con_write+d1> cmpl   $0xbfffffff,0x40(%esp,1)
+ > c017e79d <do_con_write+d9> ja     c017e7a7 <do_con_write+e3>
+ > c017e79f <do_con_write+db> movl   %edx,%eax
+ > c017e7a1 <do_con_write+dd> movl   0x40(%esp,1),%ebx
+ > c017e7a5 <do_con_write+e1> movb   (%ebx),%dl
+ > c017e7a7 <do_con_write+e3> movzbl %dl,%esi
+
+The whole user memory access is reduced to 10 x86 machine instructions.
+The instructions bracketed in the .section directives are no longer
+in the normal execution path. They are located in a different section
+of the executable file::
+
+ > objdump --disassemble --section=.fixup vmlinux
+ >
+ > c0199ff5 <.fixup+10b5> movl   $0xfffffff2,%eax
+ > c0199ffa <.fixup+10ba> xorb   %dl,%dl
+ > c0199ffc <.fixup+10bc> jmp    c017e7a7 <do_con_write+e3>
+
+And finally::
+
+ > objdump --full-contents --section=__ex_table vmlinux
+ >
+ >  c01aa7c4 93c017c0 e09f19c0 97c017c0 99c017c0  ................

+
+or in human readable byte order::
+
+ >  c01aa7c4 c017c093 c0199fe0 c017c097 c017c099  ................
+ >  c01aa7d4 c017c2f6 c0199fe9 c017e7a5 c0199ff5  ................

+                               this is the interesting part!
+ >  c01aa7e4 c0180a08 c019a001 c0180a0a c019a004  ................
+
+What happened? The assembly directives::
+
+  .section .fixup,"ax"
+  .section __ex_table,"a"
+
+told the assembler to move the following code to the specified
+sections in the ELF object file. So the instructions::
+
+  3:      movl $-14,%eax
+          xorb %dl,%dl
+          jmp 2b
+
+ended up in the .fixup section of the object file and the addresses::
+
+        .long 1b,3b
+
+ended up in the __ex_table section of the object file. 1b and 3b
+are local labels. The local label 1b (1b stands for next label 1
+backward) is the address of the instruction that might fault, i.e.
+in our case the address of the label 1 is c017e7a5:
+the original assembly code: > 1:      movb (%ebx),%dl
+and linked in vmlinux     : > c017e7a5 <do_con_write+e1> movb   (%ebx),%dl
+
+The local label 3 (backwards again) is the address of the code to handle
+the fault, in our case the actual value is c0199ff5:
+the original assembly code: > 3:      movl $-14,%eax
+and linked in vmlinux     : > c0199ff5 <.fixup+10b5> movl   $0xfffffff2,%eax
+
+The assembly code::
+
+ > .section __ex_table,"a"
+ >         .align 4
+ >         .long 1b,3b
+
+becomes the value pair::
+
+ >  c01aa7d4 c017c2f6 c0199fe9 c017e7a5 c0199ff5  ................
+                               ^this is ^this is
+                               1b       3b
+
+c017e7a5,c0199ff5 in the exception table of the kernel.
+
+So, what actually happens if a fault from kernel mode with no suitable
+vma occurs?
+
+#. access to invalid address::
+
+    > c017e7a5 <do_con_write+e1> movb   (%ebx),%dl
+#. MMU generates exception
+#. CPU calls do_page_fault
+#. do page fault calls search_exception_table (regs->eip == c017e7a5);
+#. search_exception_table looks up the address c017e7a5 in the
+   exception table (i.e. the contents of the ELF section __ex_table)
+   and returns the address of the associated fault handle code c0199ff5.
+#. do_page_fault modifies its own return address to point to the fault
+   handle code and returns.
+#. execution continues in the fault handling code.
+#. a) EAX becomes -EFAULT (== -14)
+   b) DL  becomes zero (the value we "read" from user space)
+   c) execution continues at local label 2 (address of the
+      instruction immediately after the faulting user access).
+
+The steps 8a to 8c in a certain way emulate the faulting instruction.
+
+That's it, mostly. If you look at our example, you might ask why
+we set EAX to -EFAULT in the exception handler code. Well, the
+get_user macro actually returns a value: 0, if the user access was
+successful, -EFAULT on failure. Our original code did not test this
+return value, however the inline assembly code in get_user tries to
+return -EFAULT. GCC selected EAX to return this value.
+
+NOTE:
+Due to the way that the exception table is built and needs to be ordered,
+only use exceptions for code in the .text section.  Any other section
+will cause the exception table to not be sorted correctly, and the
+exceptions will fail.
+
+Things changed when 64-bit support was added to x86 Linux. Rather than
+double the size of the exception table by expanding the two entries
+from 32-bits to 64 bits, a clever trick was used to store addresses
+as relative offsets from the table itself. The assembly code changed
+from::
+
+    .long 1b,3b
+  to:
+          .long (from) - .
+          .long (to) - .
+
+and the C-code that uses these values converts back to absolute addresses
+like this::
+
+	ex_insn_addr(const struct exception_table_entry *x)
+	{
+		return (unsigned long)&x->insn + x->insn;
+	}
+
+In v4.6 the exception table entry was expanded with a new field "handler".
+This is also 32-bits wide and contains a third relative function
+pointer which points to one of:
+
+1) ``int ex_handler_default(const struct exception_table_entry *fixup)``
+     This is legacy case that just jumps to the fixup code
+
+2) ``int ex_handler_fault(const struct exception_table_entry *fixup)``
+     This case provides the fault number of the trap that occurred at
+     entry->insn. It is used to distinguish page faults from machine
+     check.
+
+3) ``int ex_handler_ext(const struct exception_table_entry *fixup)``
+     This case is used for uaccess_err ... we need to set a flag
+     in the task structure. Before the handler functions existed this
+     case was handled by adding a large offset to the fixup to tag
+     it as special.
+
+More functions can easily be added.

-     Kernel level exception handling in Linux
-  Commentary by Joerg Pommnitz <joerg@raleigh.ibm.com>
-
-When a process runs in kernel mode, it often has to access user
-mode memory whose address has been passed by an untrusted program.
-To protect itself the kernel has to verify this address.
-
-In older versions of Linux this was done with the
-int verify_area(int type, const void * addr, unsigned long size)
-function (which has since been replaced by access_ok()).
-
-This function verified that the memory area starting at address
-'addr' and of size 'size' was accessible for the operation specified
-in type (read or write). To do this, verify_read had to look up the
-virtual memory area (vma) that contained the address addr. In the
-normal case (correctly working program), this test was successful.
-It only failed for a few buggy programs. In some kernel profiling
-tests, this normally unneeded verification used up a considerable
-amount of time.
-
-To overcome this situation, Linus decided to let the virtual memory
-hardware present in every Linux-capable CPU handle this test.
-
-How does this work?
-
-Whenever the kernel tries to access an address that is currently not
-accessible, the CPU generates a page fault exception and calls the
-page fault handler
-
-void do_page_fault(struct pt_regs *regs, unsigned long error_code)
-
-in arch/x86/mm/fault.c. The parameters on the stack are set up by
-the low level assembly glue in arch/x86/kernel/entry_32.S. The parameter
-regs is a pointer to the saved registers on the stack, error_code
-contains a reason code for the exception.
-
-do_page_fault first obtains the unaccessible address from the CPU
-control register CR2. If the address is within the virtual address
-space of the process, the fault probably occurred, because the page
-was not swapped in, write protected or something similar. However,
-we are interested in the other case: the address is not valid, there
-is no vma that contains this address. In this case, the kernel jumps
-to the bad_area label.
-
-There it uses the address of the instruction that caused the exception
-(i.e. regs->eip) to find an address where the execution can continue
-(fixup). If this search is successful, the fault handler modifies the
-return address (again regs->eip) and returns. The execution will
-continue at the address in fixup.
-
-Where does fixup point to?
-
-Since we jump to the contents of fixup, fixup obviously points
-to executable code. This code is hidden inside the user access macros.
-I have picked the get_user macro defined in arch/x86/include/asm/uaccess.h
-as an example. The definition is somewhat hard to follow, so let's peek at
-the code generated by the preprocessor and the compiler. I selected
-the get_user call in drivers/char/sysrq.c for a detailed examination.
-
-The original code in sysrq.c line 587:
-        get_user(c, buf);
-
-The preprocessor output (edited to become somewhat readable):

-The optimizer does a good job and gives us something we can actually
-understand. Can we? The actual user access is quite obvious. Thanks
-to the unified address space we can just access the address in user
-memory. But what does the .section stuff do?????
-
-To understand this we have to look at the final kernel:

-There are obviously 2 non standard ELF sections in the generated object
-file. But first we want to find out what happened to our code in the
-final kernel executable:
-
- > objdump --disassemble --section=.text vmlinux
- >
- > c017e785 <do_con_write+c1> xorl   %edx,%edx
- > c017e787 <do_con_write+c3> movl   0xc01c7bec,%eax
- > c017e78c <do_con_write+c8> cmpl   $0x18,0x314(%eax)
- > c017e793 <do_con_write+cf> je     c017e79f <do_con_write+db>
- > c017e795 <do_con_write+d1> cmpl   $0xbfffffff,0x40(%esp,1)
- > c017e79d <do_con_write+d9> ja     c017e7a7 <do_con_write+e3>
- > c017e79f <do_con_write+db> movl   %edx,%eax
- > c017e7a1 <do_con_write+dd> movl   0x40(%esp,1),%ebx
- > c017e7a5 <do_con_write+e1> movb   (%ebx),%dl
- > c017e7a7 <do_con_write+e3> movzbl %dl,%esi
-
-The whole user memory access is reduced to 10 x86 machine instructions.
-The instructions bracketed in the .section directives are no longer
-in the normal execution path. They are located in a different section
-of the executable file:
-
- > objdump --disassemble --section=.fixup vmlinux
- >
- > c0199ff5 <.fixup+10b5> movl   $0xfffffff2,%eax
- > c0199ffa <.fixup+10ba> xorb   %dl,%dl
- > c0199ffc <.fixup+10bc> jmp    c017e7a7 <do_con_write+e3>
-
-And finally:
- > objdump --full-contents --section=__ex_table vmlinux
- >
- >  c01aa7c4 93c017c0 e09f19c0 97c017c0 99c017c0  ................

-What happened? The assembly directives
-
-.section .fixup,"ax"
-.section __ex_table,"a"
-
-told the assembler to move the following code to the specified
-sections in the ELF object file. So the instructions
-3:      movl $-14,%eax
-        xorb %dl,%dl
-        jmp 2b
-ended up in the .fixup section of the object file and the addresses
-        .long 1b,3b
-ended up in the __ex_table section of the object file. 1b and 3b
-are local labels. The local label 1b (1b stands for next label 1
-backward) is the address of the instruction that might fault, i.e.
-in our case the address of the label 1 is c017e7a5:
-the original assembly code: > 1:      movb (%ebx),%dl
-and linked in vmlinux     : > c017e7a5 <do_con_write+e1> movb   (%ebx),%dl
-
-The local label 3 (backwards again) is the address of the code to handle
-the fault, in our case the actual value is c0199ff5:
-the original assembly code: > 3:      movl $-14,%eax
-and linked in vmlinux     : > c0199ff5 <.fixup+10b5> movl   $0xfffffff2,%eax
-
-The assembly code
- > .section __ex_table,"a"
- >         .align 4
- >         .long 1b,3b
-
-becomes the value pair
- >  c01aa7d4 c017c2f6 c0199fe9 c017e7a5 c0199ff5  ................
-                               ^this is ^this is
-                               1b       3b
-c017e7a5,c0199ff5 in the exception table of the kernel.
-
-So, what actually happens if a fault from kernel mode with no suitable
-vma occurs?
-
-1.) access to invalid address:
- > c017e7a5 <do_con_write+e1> movb   (%ebx),%dl
-2.) MMU generates exception
-3.) CPU calls do_page_fault
-4.) do page fault calls search_exception_table (regs->eip == c017e7a5);
-5.) search_exception_table looks up the address c017e7a5 in the
-    exception table (i.e. the contents of the ELF section __ex_table)
-    and returns the address of the associated fault handle code c0199ff5.
-6.) do_page_fault modifies its own return address to point to the fault
-    handle code and returns.
-7.) execution continues in the fault handling code.
-8.) 8a) EAX becomes -EFAULT (== -14)
-    8b) DL  becomes zero (the value we "read" from user space)
-    8c) execution continues at local label 2 (address of the
-        instruction immediately after the faulting user access).
-
-The steps 8a to 8c in a certain way emulate the faulting instruction.
-
-That's it, mostly. If you look at our example, you might ask why
-we set EAX to -EFAULT in the exception handler code. Well, the
-get_user macro actually returns a value: 0, if the user access was
-successful, -EFAULT on failure. Our original code did not test this
-return value, however the inline assembly code in get_user tries to
-return -EFAULT. GCC selected EAX to return this value.
-
-NOTE:
-Due to the way that the exception table is built and needs to be ordered,
-only use exceptions for code in the .text section.  Any other section
-will cause the exception table to not be sorted correctly, and the
-exceptions will fail.
-
-Things changed when 64-bit support was added to x86 Linux. Rather than
-double the size of the exception table by expanding the two entries
-from 32-bits to 64 bits, a clever trick was used to store addresses
-as relative offsets from the table itself. The assembly code changed
-from:
-	.long 1b,3b
-to:
-        .long (from) - .
-        .long (to) - .
-
-and the C-code that uses these values converts back to absolute addresses
-like this:
-
-	ex_insn_addr(const struct exception_table_entry *x)
-	{
-		return (unsigned long)&x->insn + x->insn;
-	}
-
-In v4.6 the exception table entry was expanded with a new field "handler".
-This is also 32-bits wide and contains a third relative function
-pointer which points to one of:
-
-1) int ex_handler_default(const struct exception_table_entry *fixup)
-   This is legacy case that just jumps to the fixup code
-2) int ex_handler_fault(const struct exception_table_entry *fixup)
-   This case provides the fault number of the trap that occurred at
-   entry->insn. It is used to distinguish page faults from machine
-   check.
-3) int ex_handler_ext(const struct exception_table_entry *fixup)
-   This case is used for uaccess_err ... we need to set a flag
-   in the task structure. Before the handler functions existed this
-   case was handled by adding a large offset to the fixup to tag
-   it as special.
-More functions can easily be added.

+IO-APIC

+
+Most (all) Intel-MP compliant SMP boards have the so-called 'IO-APIC',
+which is an enhanced interrupt controller. It enables us to route
+hardware interrupts to multiple CPUs, or to CPU groups. Without an
+IO-APIC, interrupts from hardware will be delivered only to the
+CPU which boots the operating system (usually CPU#0).
+
+Linux supports all variants of compliant SMP boards, including ones with
+multiple IO-APICs. Multiple IO-APICs are used in high-end servers to
+distribute IRQ load further.
+
+There are (a few) known breakages in certain older boards, such bugs are
+usually worked around by the kernel. If your MP-compliant SMP board does
+not boot Linux, then consult the linux-smp mailing list archives first.
+
+If your box boots fine with enabled IO-APIC IRQs, then your
+/proc/interrupts will look like this one::
+
+  hell:~> cat /proc/interrupts
+             CPU0
+    0:    1360293    IO-APIC-edge  timer
+    1:          4    IO-APIC-edge  keyboard

+  NMI:          0
+  ERR:          0
+  hell:~>
+
+Some interrupts are still listed as 'XT PIC', but this is not a problem;
+none of those IRQ sources is performance-critical.
+
+
+In the unlikely case that your board does not create a working mp-table,
+you can use the pirq= boot parameter to 'hand-construct' IRQ entries. This
+is non-trivial though and cannot be automated. One sample /etc/lilo.conf
+entry::
+
+	append="pirq=15,11,10"
+
+The actual numbers depend on your system, on your PCI cards and on their
+PCI slot position. Usually PCI slots are 'daisy chained' before they are
+connected to the PCI chipset IRQ routing facility (the incoming PIRQ1-4
+lines)::
+

+
+Every PCI card emits a PCI IRQ, which can be INTA, INTB, INTC or INTD::
+
+                               ,-.
+                         INTD--| |
+                               |S|
+                         INTC--|l|
+                               |o|
+                         INTB--|t|
+                               |x|
+                         INTA--| |
+                               `-'
+
+These INTA-D PCI IRQs are always 'local to the card', their real meaning
+depends on which slot they are in. If you look at the daisy chaining diagram,
+a card in slot4, issuing INTA IRQ, it will end up as a signal on PIRQ4 of
+the PCI chipset. Most cards issue INTA, this creates optimal distribution
+between the PIRQ lines. (distributing IRQ sources properly is not a
+necessity, PCI IRQs can be shared at will, but it's a good for performance
+to have non shared interrupts). Slot5 should be used for videocards, they
+do not use interrupts normally, thus they are not daisy chained either.
+
+so if you have your SCSI card (IRQ11) in Slot1, Tulip card (IRQ9) in
+Slot2, then you'll have to specify this pirq= line::
+
+	append="pirq=11,9"
+
+the following script tries to figure out such a default pirq= line from
+your PCI configuration::
+
+	echo -n pirq=; echo `scanpci | grep T_L | cut -c56-` | sed 's/ /,/g'
+
+note that this script won't work if you have skipped a few slots or if your
+board does not do default daisy-chaining. (or the IO-APIC has the PIRQ pins
+connected in some strange way). E.g. if in the above case you have your SCSI
+card (IRQ11) in Slot3, and have Slot1 empty::
+
+	append="pirq=0,9,11"
+
+[value '0' is a generic 'placeholder', reserved for empty (or non-IRQ emitting)
+slots.]
+
+Generally, it's always possible to find out the correct pirq= settings, just
+permute all IRQ numbers properly ... it will take some time though. An
+'incorrect' pirq line will cause the booting process to hang, or a device
+won't function properly (e.g. if it's inserted as a module).
+
+If you have 2 PCI buses, then you can use up to 8 pirq values, although such
+boards tend to have a good configuration.
+
+Be prepared that it might happen that you need some strange pirq line::
+
+	append="pirq=0,0,0,0,0,0,9,11"
+
+Use smart trial-and-error techniques to find out the correct pirq line ...
+
+Good luck and mail to linux-smp@vger.kernel.org or
+linux-kernel@vger.kernel.org if you have any problems that are not covered
+by this document.

-
-These INTA-D PCI IRQs are always 'local to the card', their real meaning
-depends on which slot they are in. If you look at the daisy chaining diagram,
-a card in slot4, issuing INTA IRQ, it will end up as a signal on PIRQ4 of
-the PCI chipset. Most cards issue INTA, this creates optimal distribution
-between the PIRQ lines. (distributing IRQ sources properly is not a
-necessity, PCI IRQs can be shared at will, but it's a good for performance
-to have non shared interrupts). Slot5 should be used for videocards, they
-do not use interrupts normally, thus they are not daisy chained either.
-
-so if you have your SCSI card (IRQ11) in Slot1, Tulip card (IRQ9) in
-Slot2, then you'll have to specify this pirq= line:
-
-	append="pirq=11,9"
-
-the following script tries to figure out such a default pirq= line from
-your PCI configuration:
-
-	echo -n pirq=; echo `scanpci | grep T_L | cut -c56-` | sed 's/ /,/g'
-
-note that this script won't work if you have skipped a few slots or if your
-board does not do default daisy-chaining. (or the IO-APIC has the PIRQ pins
-connected in some strange way). E.g. if in the above case you have your SCSI
-card (IRQ11) in Slot3, and have Slot1 empty:
-
-	append="pirq=0,9,11"
-
-[value '0' is a generic 'placeholder', reserved for empty (or non-IRQ emitting)
-slots.]
-
-Generally, it's always possible to find out the correct pirq= settings, just
-permute all IRQ numbers properly ... it will take some time though. An
-'incorrect' pirq line will cause the booting process to hang, or a device
-won't function properly (e.g. if it's inserted as a module).
-
-If you have 2 PCI buses, then you can use up to 8 pirq values, although such
-boards tend to have a good configuration.
-
-Be prepared that it might happen that you need some strange pirq line:
-
-	append="pirq=0,0,0,0,0,0,9,11"
-
-Use smart trial-and-error techniques to find out the correct pirq line ...
-
-Good luck and mail to linux-smp@vger.kernel.org or
-linux-kernel@vger.kernel.org if you have any problems that are not covered
-by this document.

+Intel(R) Memory Protection Extensions (MPX)
+===========================================
+
+Intel(R) MPX Overview
+=====================
+
+Intel(R) Memory Protection Extensions (Intel(R) MPX) is a new capability
+introduced into Intel Architecture. Intel MPX provides hardware features
+that can be used in conjunction with compiler changes to check memory
+references, for those references whose compile-time normal intentions are
+usurped at runtime due to buffer overflow or underflow.
+
+You can tell if your CPU supports MPX by looking in /proc/cpuinfo::
+
+	cat /proc/cpuinfo  | grep ' mpx '
+
+For more information, please refer to Intel(R) Architecture Instruction
+Set Extensions Programming Reference, Chapter 9: Intel(R) Memory Protection
+Extensions.
+
+Note: As of December 2014, no hardware with MPX is available but it is
+possible to use SDE (Intel(R) Software Development Emulator) instead, which
+can be downloaded from
+http://software.intel.com/en-us/articles/intel-software-development-emulator
+
+
+How to get the advantage of MPX
+===============================
+
+For MPX to work, changes are required in the kernel, binutils and compiler.
+No source changes are required for applications, just a recompile.
+
+There are a lot of moving parts of this to all work right. The following
+is how we expect the compiler, application and kernel to work together.
+
+1) Application developer compiles with -fmpx. The compiler will add the
+   instrumentation as well as some setup code called early after the app
+   starts. New instruction prefixes are noops for old CPUs.
+2) That setup code allocates (virtual) space for the "bounds directory",
+   points the "bndcfgu" register to the directory (must also set the valid
+   bit) and notifies the kernel (via the new prctl(PR_MPX_ENABLE_MANAGEMENT))
+   that the app will be using MPX.  The app must be careful not to access
+   the bounds tables between the time when it populates "bndcfgu" and
+   when it calls the prctl().  This might be hard to guarantee if the app
+   is compiled with MPX.  You can add "__attribute__((bnd_legacy))" to
+   the function to disable MPX instrumentation to help guarantee this.
+   Also be careful not to call out to any other code which might be
+   MPX-instrumented.
+3) The kernel detects that the CPU has MPX, allows the new prctl() to
+   succeed, and notes the location of the bounds directory. Userspace is
+   expected to keep the bounds directory at that location. We note it
+   instead of reading it each time because the 'xsave' operation needed
+   to access the bounds directory register is an expensive operation.
+4) If the application needs to spill bounds out of the 4 registers, it
+   issues a bndstx instruction. Since the bounds directory is empty at
+   this point, a bounds fault (#BR) is raised, the kernel allocates a
+   bounds table (in the user address space) and makes the relevant entry
+   in the bounds directory point to the new table.
+5) If the application violates the bounds specified in the bounds registers,
+   a separate kind of #BR is raised which will deliver a signal with
+   information about the violation in the 'struct siginfo'.
+6) Whenever memory is freed, we know that it can no longer contain valid
+   pointers, and we attempt to free the associated space in the bounds
+   tables. If an entire table becomes unused, we will attempt to free
+   the table and remove the entry in the directory.
+
+To summarize, there are essentially three things interacting here:
+
+GCC with -fmpx:
+ * enables annotation of code with MPX instructions and prefixes
+ * inserts code early in the application to call in to the "gcc runtime"
+GCC MPX Runtime:
+ * Checks for hardware MPX support in cpuid leaf
+ * allocates virtual space for the bounds directory (malloc() essentially)
+ * points the hardware BNDCFGU register at the directory
+ * calls a new prctl(PR_MPX_ENABLE_MANAGEMENT) to notify the kernel to
+   start managing the bounds directories
+Kernel MPX Code:
+ * Checks for hardware MPX support in cpuid leaf
+ * Handles #BR exceptions and sends SIGSEGV to the app when it violates
+   bounds, like during a buffer overflow.
+ * When bounds are spilled in to an unallocated bounds table, the kernel
+   notices in the #BR exception, allocates the virtual space, then
+   updates the bounds directory to point to the new table. It keeps
+   special track of the memory with a VM_MPX flag.
+ * Frees unused bounds tables at the time that the memory they described
+   is unmapped.
+
+
+How does MPX kernel code work
+=============================
+
+Handling #BR faults caused by MPX
+---------------------------------
+
+When MPX is enabled, there are 2 new situations that can generate
+#BR faults.
+
+  * new bounds tables (BT) need to be allocated to save bounds.
+  * bounds violation caused by MPX instructions.
+
+We hook #BR handler to handle these two new situations.
+
+On-demand kernel allocation of bounds tables
+--------------------------------------------
+
+MPX only has 4 hardware registers for storing bounds information. If
+MPX-enabled code needs more than these 4 registers, it needs to spill
+them somewhere. It has two special instructions for this which allow
+the bounds to be moved between the bounds registers and some new "bounds
+tables".
+
+#BR exceptions are a new class of exceptions just for MPX. They are
+similar conceptually to a page fault and will be raised by the MPX
+hardware during both bounds violations or when the tables are not
+present. The kernel handles those #BR exceptions for not-present tables
+by carving the space out of the normal processes address space and then
+pointing the bounds-directory over to it.
+
+The tables need to be accessed and controlled by userspace because
+the instructions for moving bounds in and out of them are extremely
+frequent. They potentially happen every time a register points to
+memory. Any direct kernel involvement (like a syscall) to access the
+tables would obviously destroy performance.
+
+Why not do this in userspace? MPX does not strictly require anything in
+the kernel. It can theoretically be done completely from userspace. Here
+are a few ways this could be done. We don't think any of them are practical
+in the real-world, but here they are.
+
+:Q: Can virtual space simply be reserved for the bounds tables so that we
+    never have to allocate them?
+:A: MPX-enabled application will possibly create a lot of bounds tables in
+    process address space to save bounds information. These tables can take
+    up huge swaths of memory (as much as 80% of the memory on the system)
+    even if we clean them up aggressively. In the worst-case scenario, the
+    tables can be 4x the size of the data structure being tracked. IOW, a
+    1-page structure can require 4 bounds-table pages. An X-GB virtual
+    area needs 4*X GB of virtual space, plus 2GB for the bounds directory.
+    If we were to preallocate them for the 128TB of user virtual address
+    space, we would need to reserve 512TB+2GB, which is larger than the
+    entire virtual address space today. This means they can not be reserved
+    ahead of time. Also, a single process's pre-populated bounds directory
+    consumes 2GB of virtual *AND* physical memory. IOW, it's completely
+    infeasible to prepopulate bounds directories.
+
+:Q: Can we preallocate bounds table space at the same time memory is
+    allocated which might contain pointers that might eventually need
+    bounds tables?
+:A: This would work if we could hook the site of each and every memory
+    allocation syscall. This can be done for small, constrained applications.
+    But, it isn't practical at a larger scale since a given app has no
+    way of controlling how all the parts of the app might allocate memory
+    (think libraries). The kernel is really the only place to intercept
+    these calls.
+
+:Q: Could a bounds fault be handed to userspace and the tables allocated
+    there in a signal handler instead of in the kernel?
+:A: mmap() is not on the list of safe async handler functions and even
+    if mmap() would work it still requires locking or nasty tricks to
+    keep track of the allocation state there.
+
+Having ruled out all of the userspace-only approaches for managing
+bounds tables that we could think of, we create them on demand in
+the kernel.
+
+Decoding MPX instructions
+-------------------------
+
+If a #BR is generated due to a bounds violation caused by MPX.
+We need to decode MPX instructions to get violation address and
+set this address into extended struct siginfo.
+
+The _sigfault field of struct siginfo is extended as follow::
+
+  87		/* SIGILL, SIGFPE, SIGSEGV, SIGBUS */
+  88		struct {
+  89			void __user *_addr; /* faulting insn/memory ref. */
+  90 #ifdef __ARCH_SI_TRAPNO
+  91			int _trapno;	/* TRAP # which caused the signal */
+  92 #endif
+  93			short _addr_lsb; /* LSB of the reported address */
+  94			struct {
+  95				void __user *_lower;
+  96				void __user *_upper;
+  97			} _addr_bnd;
+  98		} _sigfault;
+
+The '_addr' field refers to violation address, and new '_addr_and'
+field refers to the upper/lower bounds when a #BR is caused.
+
+Glibc will be also updated to support this new siginfo. So user
+can get violation address and bounds when bounds violations occur.
+
+Cleanup unused bounds tables
+----------------------------
+
+When a BNDSTX instruction attempts to save bounds to a bounds directory
+entry marked as invalid, a #BR is generated. This is an indication that
+no bounds table exists for this entry. In this case the fault handler
+will allocate a new bounds table on demand.
+
+Since the kernel allocated those tables on-demand without userspace
+knowledge, it is also responsible for freeing them when the associated
+mappings go away.
+
+Here, the solution for this issue is to hook do_munmap() to check
+whether one process is MPX enabled. If yes, those bounds tables covered
+in the virtual address region which is being unmapped will be freed also.
+
+Adding new prctl commands
+-------------------------
+
+Two new prctl commands are added to enable and disable MPX bounds tables
+management in kernel.
+::
+
+  155	#define PR_MPX_ENABLE_MANAGEMENT	43
+  156	#define PR_MPX_DISABLE_MANAGEMENT	44
+
+Runtime library in userspace is responsible for allocation of bounds
+directory. So kernel have to use XSAVE instruction to get the base
+of bounds directory from BNDCFG register.
+
+But XSAVE is expected to be very expensive. In order to do performance
+optimization, we have to get the base of bounds directory and save it
+into struct mm_struct to be used in future during PR_MPX_ENABLE_MANAGEMENT
+command execution.
+
+
+Special rules
+=============
+
+1) If userspace is requesting help from the kernel to do the management
+of bounds tables, it may not create or modify entries in the bounds directory.
+
+Certainly users can allocate bounds tables and forcibly point the bounds
+directory at them through XSAVE instruction, and then set valid bit
+of bounds entry to have this entry valid.  But, the kernel will decline
+to assist in managing these tables.
+
+2) Userspace may not take multiple bounds directory entries and point
+them at the same bounds table.
+
+This is allowed architecturally.  See more information "Intel(R) Architecture
+Instruction Set Extensions Programming Reference" (9.3.4).
+
+However, if users did this, the kernel might be fooled in to unmapping an
+in-use bounds table since it does not recognize sharing.

-================================
-
-Handling #BR faults caused by MPX
----------------------------------
-
-When MPX is enabled, there are 2 new situations that can generate
-#BR faults.
-  * new bounds tables (BT) need to be allocated to save bounds.
-  * bounds violation caused by MPX instructions.
-
-We hook #BR handler to handle these two new situations.
-
-On-demand kernel allocation of bounds tables
---------------------------------------------
-
-MPX only has 4 hardware registers for storing bounds information. If
-MPX-enabled code needs more than these 4 registers, it needs to spill
-them somewhere. It has two special instructions for this which allow
-the bounds to be moved between the bounds registers and some new "bounds
-tables".
-
-#BR exceptions are a new class of exceptions just for MPX. They are
-similar conceptually to a page fault and will be raised by the MPX
-hardware during both bounds violations or when the tables are not
-present. The kernel handles those #BR exceptions for not-present tables
-by carving the space out of the normal processes address space and then

-   never have to allocate them?
-A: MPX-enabled application will possibly create a lot of bounds tables in
-   process address space to save bounds information. These tables can take

-   even if we clean them up aggressively. In the worst-case scenario, the

-   If we were to preallocate them for the 128TB of user virtual address
-   space, we would need to reserve 512TB+2GB, which is larger than the
-   entire virtual address space today. This means they can not be reserved

-
-Decoding MPX instructions
--------------------------
-
-If a #BR is generated due to a bounds violation caused by MPX.
-We need to decode MPX instructions to get violation address and
-set this address into extended struct siginfo.
-
-The _sigfault field of struct siginfo is extended as follow:
-
-87		/* SIGILL, SIGFPE, SIGSEGV, SIGBUS */
-88		struct {
-89			void __user *_addr; /* faulting insn/memory ref. */
-90 #ifdef __ARCH_SI_TRAPNO
-91			int _trapno;	/* TRAP # which caused the signal */
-92 #endif
-93			short _addr_lsb; /* LSB of the reported address */
-94			struct {
-95				void __user *_lower;
-96				void __user *_upper;
-97			} _addr_bnd;
-98		} _sigfault;
-
-The '_addr' field refers to violation address, and new '_addr_and'
-field refers to the upper/lower bounds when a #BR is caused.
-
-Glibc will be also updated to support this new siginfo. So user
-can get violation address and bounds when bounds violations occur.
-
-Cleanup unused bounds tables
-----------------------------
-
-When a BNDSTX instruction attempts to save bounds to a bounds directory
-entry marked as invalid, a #BR is generated. This is an indication that
-no bounds table exists for this entry. In this case the fault handler
-will allocate a new bounds table on demand.
-
-Since the kernel allocated those tables on-demand without userspace
-knowledge, it is also responsible for freeing them when the associated
-mappings go away.
-
-Here, the solution for this issue is to hook do_munmap() to check
-whether one process is MPX enabled. If yes, those bounds tables covered
-in the virtual address region which is being unmapped will be freed also.
-
-Adding new prctl commands
--------------------------
-
-Two new prctl commands are added to enable and disable MPX bounds tables
-management in kernel.
-
-155	#define PR_MPX_ENABLE_MANAGEMENT	43
-156	#define PR_MPX_DISABLE_MANAGEMENT	44
-
-Runtime library in userspace is responsible for allocation of bounds
-directory. So kernel have to use XSAVE instruction to get the base
-of bounds directory from BNDCFG register.
-
-But XSAVE is expected to be very expensive. In order to do performance
-optimization, we have to get the base of bounds directory and save it
-into struct mm_struct to be used in future during PR_MPX_ENABLE_MANAGEMENT
-command execution.
-
-
-4. Special rules
-================
-
-1) If userspace is requesting help from the kernel to do the management
-of bounds tables, it may not create or modify entries in the bounds directory.
-
-Certainly users can allocate bounds tables and forcibly point the bounds
-directory at them through XSAVE instruction, and then set valid bit
-of bounds entry to have this entry valid.  But, the kernel will decline
-to assist in managing these tables.
-
-2) Userspace may not take multiple bounds directory entries and point
-them at the same bounds table.
-
-This is allowed architecturally.  See more information "Intel(R) Architecture
-Instruction Set Extensions Programming Reference" (9.3.4).
-
-However, if users did this, the kernel might be fooled in to unmapping an
-in-use bounds table since it does not recognize sharing.

-Kernel stacks on x86-64 bit
----------------------------
-
-Most of the text from Keith Owens, hacked by AK
-
-x86_64 page size (PAGE_SIZE) is 4K.
-
-Like all other architectures, x86_64 has a kernel stack for every
-active thread.  These thread stacks are THREAD_SIZE (2*PAGE_SIZE) big.
-These stacks contain useful data as long as a thread is alive or a
-zombie. While the thread is in user space the kernel stack is empty
-except for the thread_info structure at the bottom.
-
-In addition to the per thread stacks, there are specialized stacks
-associated with each CPU.  These stacks are only used while the kernel
-is in control on that CPU; when a CPU returns to user space the
-specialized stacks contain no useful data.  The main CPU stacks are:
-
-* Interrupt stack.  IRQ_STACK_SIZE
-
-  Used for external hardware interrupts.  If this is the first external
-  hardware interrupt (i.e. not a nested hardware interrupt) then the
-  kernel switches from the current task to the interrupt stack.  Like
-  the split thread and interrupt stacks on i386, this gives more room
-  for kernel interrupt processing without having to increase the size
-  of every per thread stack.
-
-  The interrupt stack is also used when processing a softirq.
-
-Switching to the kernel interrupt stack is done by software based on a
-per CPU interrupt nest counter. This is needed because x86-64 "IST"
-hardware stacks cannot nest without races.
-
-x86_64 also has a feature which is not available on i386, the ability
-to automatically switch to a new stack for designated events such as
-double fault or NMI, which makes it easier to handle these unusual
-events on x86_64.  This feature is called the Interrupt Stack Table
-(IST).  There can be up to 7 IST entries per CPU. The IST code is an
-index into the Task State Segment (TSS). The IST entries in the TSS
-point to dedicated stacks; each stack can be a different size.
-
-An IST is selected by a non-zero value in the IST field of an
-interrupt-gate descriptor.  When an interrupt occurs and the hardware
-loads such a descriptor, the hardware automatically sets the new stack
-pointer based on the IST value, then invokes the interrupt handler.  If
-the interrupt came from user mode, then the interrupt handler prologue
-will switch back to the per-thread stack.  If software wants to allow
-nested IST interrupts then the handler must adjust the IST values on
-entry to and exit from the interrupt handler.  (This is occasionally
-done, e.g. for debug exceptions.)
-
-Events with different IST codes (i.e. with different stacks) can be
-nested.  For example, a debug interrupt can safely be interrupted by an
-NMI.  arch/x86_64/kernel/entry.S::paranoidentry adjusts the stack
-pointers on entry to and exit from all IST events, in theory allowing
-IST events with the same code to be nested.  However in most cases, the
-stack size allocated to an IST assumes no nesting for the same code.
-If that assumption is ever broken then the stacks will become corrupt.
-
-The currently assigned IST stacks are :-
-
-* DOUBLEFAULT_STACK.  EXCEPTION_STKSZ (PAGE_SIZE).
-
-  Used for interrupt 8 - Double Fault Exception (#DF).
-
-  Invoked when handling one exception causes another exception. Happens
-  when the kernel is very confused (e.g. kernel stack pointer corrupt).
-  Using a separate stack allows the kernel to recover from it well enough
-  in many cases to still output an oops.
-
-* NMI_STACK.  EXCEPTION_STKSZ (PAGE_SIZE).
-
-  Used for non-maskable interrupts (NMI).
-
-  NMI can be delivered at any time, including when the kernel is in the
-  middle of switching stacks.  Using IST for NMI events avoids making
-  assumptions about the previous state of the kernel stack.
-
-* DEBUG_STACK.  DEBUG_STKSZ
-
-  Used for hardware debug interrupts (interrupt 1) and for software
-  debug interrupts (INT3).
-
-  When debugging a kernel, debug interrupts (both hardware and
-  software) can occur at any time.  Using IST for these interrupts
-  avoids making assumptions about the previous state of the kernel
-  stack.
-
-* MCE_STACK.  EXCEPTION_STKSZ (PAGE_SIZE).
-
-  Used for interrupt 18 - Machine Check Exception (#MC).
-
-  MCE can be delivered at any time, including when the kernel is in the
-  middle of switching stacks.  Using IST for MCE events avoids making
-  assumptions about the previous state of the kernel stack.

-keeps popping up, here's an indepth explanation. It helps if the reader
-stares at print_context_stack() and the whole machinery in and around
-arch/x86/kernel/dumpstack.c.
-
-Adapted from Ingo's mail, Message-ID: <20150521101614.GA10889@gmail.com>:
-
-We always scan the full kernel stack for return addresses stored on
-the kernel stack(s) [*], from stack top to stack bottom, and print out
-anything that 'looks like' a kernel text address.
-
-If it fits into the frame pointer chain, we print it without a question
-mark, knowing that it's part of the real backtrace.
-
-If the address does not fit into our expected frame pointer chain we
-still print it, but we print a '?'. It can mean two things:
-
- - either the address is not part of the call chain: it's just stale
-   values on the kernel stack, from earlier function calls. This is
-   the common case.
-
- - or it is part of the call chain, but the frame pointer was not set
-   up properly within the function, so we don't recognize it.
-
-This way we will always print out the real call chain (plus a few more
-entries), regardless of whether the frame pointer was set up correctly
-or not - but in most cases we'll get the call chain right as well. The
-entries printed are strictly in stack order, so you can deduce more
-information from that as well.
-
-The most important property of this method is that we _never_ lose
-information: we always strive to print _all_ addresses on the stack(s)
-that look like kernel text addresses, so if debug information is wrong,
-we still print out the real call chain as well - just with more question

-
-[*] For things like IRQ and IST stacks, we also scan those stacks, in

+Microarchitectural Data Sampling (MDS) mitigation
+=================================================
+
+.. _mds:
+
+Overview
+--------
+
+Microarchitectural Data Sampling (MDS) is a family of side channel attacks
+on internal buffers in Intel CPUs. The variants are:
+
+ - Microarchitectural Store Buffer Data Sampling (MSBDS) (CVE-2018-12126)
+ - Microarchitectural Fill Buffer Data Sampling (MFBDS) (CVE-2018-12130)
+ - Microarchitectural Load Port Data Sampling (MLPDS) (CVE-2018-12127)
+ - Microarchitectural Data Sampling Uncacheable Memory (MDSUM) (CVE-2019-11091)
+
+MSBDS leaks Store Buffer Entries which can be speculatively forwarded to a
+dependent load (store-to-load forwarding) as an optimization. The forward
+can also happen to a faulting or assisting load operation for a different
+memory address, which can be exploited under certain conditions. Store
+buffers are partitioned between Hyper-Threads so cross thread forwarding is
+not possible. But if a thread enters or exits a sleep state the store
+buffer is repartitioned which can expose data from one thread to the other.
+
+MFBDS leaks Fill Buffer Entries. Fill buffers are used internally to manage
+L1 miss situations and to hold data which is returned or sent in response
+to a memory or I/O operation. Fill buffers can forward data to a load
+operation and also write data to the cache. When the fill buffer is
+deallocated it can retain the stale data of the preceding operations which
+can then be forwarded to a faulting or assisting load operation, which can
+be exploited under certain conditions. Fill buffers are shared between
+Hyper-Threads so cross thread leakage is possible.
+
+MLPDS leaks Load Port Data. Load ports are used to perform load operations
+from memory or I/O. The received data is then forwarded to the register
+file or a subsequent operation. In some implementations the Load Port can
+contain stale data from a previous operation which can be forwarded to
+faulting or assisting loads under certain conditions, which again can be
+exploited eventually. Load ports are shared between Hyper-Threads so cross
+thread leakage is possible.
+
+MDSUM is a special case of MSBDS, MFBDS and MLPDS. An uncacheable load from
+memory that takes a fault or assist can leave data in a microarchitectural
+structure that may later be observed using one of the same methods used by
+MSBDS, MFBDS or MLPDS.
+
+Exposure assumptions
+--------------------
+
+It is assumed that attack code resides in user space or in a guest with one
+exception. The rationale behind this assumption is that the code construct
+needed for exploiting MDS requires:
+
+ - to control the load to trigger a fault or assist
+
+ - to have a disclosure gadget which exposes the speculatively accessed
+   data for consumption through a side channel.
+
+ - to control the pointer through which the disclosure gadget exposes the
+   data
+
+The existence of such a construct in the kernel cannot be excluded with
+100% certainty, but the complexity involved makes it extremly unlikely.
+
+There is one exception, which is untrusted BPF. The functionality of
+untrusted BPF is limited, but it needs to be thoroughly investigated
+whether it can be used to create such a construct.
+
+
+Mitigation strategy
+-------------------
+
+All variants have the same mitigation strategy at least for the single CPU
+thread case (SMT off): Force the CPU to clear the affected buffers.
+
+This is achieved by using the otherwise unused and obsolete VERW
+instruction in combination with a microcode update. The microcode clears
+the affected CPU buffers when the VERW instruction is executed.
+
+For virtualization there are two ways to achieve CPU buffer
+clearing. Either the modified VERW instruction or via the L1D Flush
+command. The latter is issued when L1TF mitigation is enabled so the extra
+VERW can be avoided. If the CPU is not affected by L1TF then VERW needs to
+be issued.
+
+If the VERW instruction with the supplied segment selector argument is
+executed on a CPU without the microcode update there is no side effect
+other than a small number of pointlessly wasted CPU cycles.
+
+This does not protect against cross Hyper-Thread attacks except for MSBDS
+which is only exploitable cross Hyper-thread when one of the Hyper-Threads
+enters a C-state.
+
+The kernel provides a function to invoke the buffer clearing:
+
+    mds_clear_cpu_buffers()
+
+The mitigation is invoked on kernel/userspace, hypervisor/guest and C-state
+(idle) transitions.
+
+As a special quirk to address virtualization scenarios where the host has
+the microcode updated, but the hypervisor does not (yet) expose the
+MD_CLEAR CPUID bit to guests, the kernel issues the VERW instruction in the
+hope that it might actually clear the buffers. The state is reflected
+accordingly.
+
+According to current knowledge additional mitigations inside the kernel
+itself are not required because the necessary gadgets to expose the leaked
+data cannot be controlled in a way which allows exploitation from malicious
+user space or VM guests.
+
+Kernel internal mitigation modes
+--------------------------------
+
+ ======= ============================================================
+ off      Mitigation is disabled. Either the CPU is not affected or
+          mds=off is supplied on the kernel command line
+
+ full     Mitigation is enabled. CPU is affected and MD_CLEAR is
+          advertised in CPUID.
+
+ vmwerv	  Mitigation is enabled. CPU is affected and MD_CLEAR is not
+	  advertised in CPUID. That is mainly for virtualization
+	  scenarios where the host has the updated microcode but the
+	  hypervisor does not expose MD_CLEAR in CPUID. It's a best
+	  effort approach without guarantee.
+ ======= ============================================================
+
+If the CPU is affected and mds=off is not supplied on the kernel command
+line then the kernel selects the appropriate mitigation mode depending on
+the availability of the MD_CLEAR CPUID bit.
+
+Mitigation points
+-----------------
+
+1. Return to user space
+^^^^^^^^^^^^^^^^^^^^^^^
+
+   When transitioning from kernel to user space the CPU buffers are flushed
+   on affected CPUs when the mitigation is not disabled on the kernel
+   command line. The migitation is enabled through the static key
+   mds_user_clear.
+
+   The mitigation is invoked in prepare_exit_to_usermode() which covers
+   all but one of the kernel to user space transitions.  The exception
+   is when we return from a Non Maskable Interrupt (NMI), which is
+   handled directly in do_nmi().
+
+   (The reason that NMI is special is that prepare_exit_to_usermode() can
+    enable IRQs.  In NMI context, NMIs are blocked, and we don't want to
+    enable IRQs with NMIs blocked.)
+
+
+2. C-State transition
+^^^^^^^^^^^^^^^^^^^^^
+
+   When a CPU goes idle and enters a C-State the CPU buffers need to be
+   cleared on affected CPUs when SMT is active. This addresses the
+   repartitioning of the store buffer when one of the Hyper-Threads enters
+   a C-State.
+
+   When SMT is inactive, i.e. either the CPU does not support it or all
+   sibling threads are offline CPU buffer clearing is not required.
+
+   The idle clearing is enabled on CPUs which are only affected by MSBDS
+   and not by any other MDS variant. The other MDS variants cannot be
+   protected against cross Hyper-Thread attacks because the Fill Buffer and
+   the Load Ports are shared. So on CPUs affected by other variants, the
+   idle clearing would be a window dressing exercise and is therefore not
+   activated.
+
+   The invocation is controlled by the static key mds_idle_clear which is
+   switched depending on the chosen mitigation mode and the SMT state of
+   the system.
+
+   The buffer clear is only invoked before entering the C-State to prevent
+   that stale data from the idling CPU from spilling to the Hyper-Thread
+   sibling after the store buffer got repartitioned and all entries are
+   available to the non idle sibling.
+
+   When coming out of idle the store buffer is partitioned again so each
+   sibling has half of it available. The back from idle CPU could be then
+   speculatively exposed to contents of the sibling. The buffers are
+   flushed either on exit to user space or on VMENTER so malicious code
+   in user space or the guest cannot speculatively access them.
+
+   The mitigation is hooked into all variants of halt()/mwait(), but does
+   not cover the legacy ACPI IO-Port mechanism because the ACPI idle driver
+   has been superseded by the intel_idle driver around 2010 and is
+   preferred on all affected CPUs which are expected to gain the MD_CLEAR
+   functionality in microcode. Aside of that the IO-Port mechanism is a
+   legacy interface which is only used on older systems which are either
+   not affected or do not receive microcode updates anymore.

+==========================
+The Linux Microcode Loader
+==========================
+
+:Authors: - Fenghua Yu <fenghua.yu@intel.com>
+          - Borislav Petkov <bp@suse.de>
+
+The kernel has a x86 microcode loading facility which is supposed to
+provide microcode loading methods in the OS. Potential use cases are
+updating the microcode on platforms beyond the OEM End-Of-Life support,
+and updating the microcode on long-running systems without rebooting.
+
+The loader supports three loading methods:
+
+Early load microcode
+====================
+
+The kernel can update microcode very early during boot. Loading
+microcode early can fix CPU issues before they are observed during
+kernel boot time.
+
+The microcode is stored in an initrd file. During boot, it is read from
+it and loaded into the CPU cores.
+
+The format of the combined initrd image is microcode in (uncompressed)
+cpio format followed by the (possibly compressed) initrd image. The
+loader parses the combined initrd image during boot.
+
+The microcode files in cpio name space are:
+
+on Intel:
+  /*(DEBLOBBED)*/
+on AMD  :
+  /*(DEBLOBBED)*/
+
+During BSP (BootStrapping Processor) boot (pre-SMP), the kernel
+scans the microcode file in the initrd. If microcode matching the
+CPU is found, it will be applied in the BSP and later on in all APs

+=================
+

+  CONFIG_EXTRA_FIRMWARE="/*(DEBLOBBED)*/ /*(DEBLOBBED)*/"
+  CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
+
+This basically means, you have the following tree structure locally::
+
+  /*(DEBLOBBED)*/
+
+so that the build system can find those files and integrate them into
+the final kernel image. The early loader finds them and applies them.
+
+Needless to say, this method is not the most flexible one because it
+requires rebuilding the kernel each time updated microcode from the CPU
+vendor is available.

-	The Linux Microcode Loader
-
-Authors: Fenghua Yu <fenghua.yu@intel.com>

-
-The kernel has a x86 microcode loading facility which is supposed to
-provide microcode loading methods in the OS. Potential use cases are
-updating the microcode on platforms beyond the OEM End-Of-Life support,
-and updating the microcode on long-running systems without rebooting.
-
-The loader supports three loading methods:
-
-1. Early load microcode
-=======================
-
-The kernel can update microcode very early during boot. Loading
-microcode early can fix CPU issues before they are observed during
-kernel boot time.
-
-The microcode is stored in an initrd file. During boot, it is read from
-it and loaded into the CPU cores.
-
-The format of the combined initrd image is microcode in (uncompressed)
-cpio format followed by the (possibly compressed) initrd image. The
-loader parses the combined initrd image during boot.
-
-The microcode files in cpio name space are:
-
-on Intel: /*(DEBLOBBED)*/
-on AMD  : /*(DEBLOBBED)*/
-
-During BSP (BootStrapping Processor) boot (pre-SMP), the kernel
-scans the microcode file in the initrd. If microcode matching the
-CPU is found, it will be applied in the BSP and later on in all APs
-(Application Processors).
-
-The loader also saves the matching microcode for the CPU in memory.
-Thus, the cached microcode patch is applied when CPUs resume from a
-sleep state.
-
-Here's a crude example how to prepare an initrd with microcode (this is
-normally done automatically by the distribution, when recreating the
-initrd, so you don't really have to do it yourself. It is documented
-here for future reference only).

+=========================================
+MTRR (Memory Type Range Register) control
+=========================================
+
+:Authors: - Richard Gooch <rgooch@atnf.csiro.au> - 3 Jun 1999
+          - Luis R. Rodriguez <mcgrof@do-not-panic.com> - April 9, 2015
+
+
+Phasing out MTRR use
+====================
+
+MTRR use is replaced on modern x86 hardware with PAT. Direct MTRR use by
+drivers on Linux is now completely phased out, device drivers should use
+arch_phys_wc_add() in combination with ioremap_wc() to make MTRR effective on
+non-PAT systems while a no-op but equally effective on PAT enabled systems.
+
+Even if Linux does not use MTRRs directly, some x86 platform firmware may still
+set up MTRRs early before booting the OS. They do this as some platform
+firmware may still have implemented access to MTRRs which would be controlled
+and handled by the platform firmware directly. An example of platform use of
+MTRRs is through the use of SMI handlers, one case could be for fan control,
+the platform code would need uncachable access to some of its fan control
+registers. Such platform access does not need any Operating System MTRR code in
+place other than mtrr_type_lookup() to ensure any OS specific mapping requests
+are aligned with platform MTRR setup. If MTRRs are only set up by the platform
+firmware code though and the OS does not make any specific MTRR mapping
+requests mtrr_type_lookup() should always return MTRR_TYPE_INVALID.
+
+For details refer to :doc:`pat`.
+
+.. tip::
+  On Intel P6 family processors (Pentium Pro, Pentium II and later)
+  the Memory Type Range Registers (MTRRs) may be used to control
+  processor access to memory ranges. This is most useful when you have
+  a video (VGA) card on a PCI or AGP bus. Enabling write-combining
+  allows bus write transfers to be combined into a larger transfer
+  before bursting over the PCI/AGP bus. This can increase performance
+  of image write operations 2.5 times or more.
+
+  The Cyrix 6x86, 6x86MX and M II processors have Address Range
+  Registers (ARRs) which provide a similar functionality to MTRRs. For
+  these, the ARRs are used to emulate the MTRRs.
+
+  The AMD K6-2 (stepping 8 and above) and K6-3 processors have two
+  MTRRs. These are supported.  The AMD Athlon family provide 8 Intel
+  style MTRRs.
+
+  The Centaur C6 (WinChip) has 8 MCRs, allowing write-combining. These
+  are supported.
+
+  The VIA Cyrix III and VIA C3 CPUs offer 8 Intel style MTRRs.
+
+  The CONFIG_MTRR option creates a /proc/mtrr file which may be used
+  to manipulate your MTRRs. Typically the X server should use
+  this. This should have a reasonably generic interface so that
+  similar control registers on other processors can be easily
+  supported.
+
+There are two interfaces to /proc/mtrr: one is an ASCII interface
+which allows you to read and write. The other is an ioctl()
+interface. The ASCII interface is meant for administration. The
+ioctl() interface is meant for C programs (i.e. the X server). The
+interfaces are described below, with sample commands and C code.
+
+
+Reading MTRRs from the shell
+============================
+::
+
+  % cat /proc/mtrr
+  reg00: base=0x00000000 (   0MB), size= 128MB: write-back, count=1
+  reg01: base=0x08000000 ( 128MB), size=  64MB: write-back, count=1
+
+Creating MTRRs from the C-shell::
+
+  # echo "base=0xf8000000 size=0x400000 type=write-combining" >! /proc/mtrr
+
+or if you use bash::
+
+  # echo "base=0xf8000000 size=0x400000 type=write-combining" >| /proc/mtrr
+
+And the result thereof::
+
+  % cat /proc/mtrr
+  reg00: base=0x00000000 (   0MB), size= 128MB: write-back, count=1
+  reg01: base=0x08000000 ( 128MB), size=  64MB: write-back, count=1
+  reg02: base=0xf8000000 (3968MB), size=   4MB: write-combining, count=1
+
+This is for video RAM at base address 0xf8000000 and size 4 megabytes. To
+find out your base address, you need to look at the output of your X
+server, which tells you where the linear framebuffer address is. A
+typical line that you may get is::
+
+  (--) S3: PCI: 968 rev 0, Linear FB @ 0xf8000000
+
+Note that you should only use the value from the X server, as it may
+move the framebuffer base address, so the only value you can trust is
+that reported by the X server.
+
+To find out the size of your framebuffer (what, you don't actually
+know?), the following line will tell you::
+
+  (--) S3: videoram:  4096k
+
+That's 4 megabytes, which is 0x400000 bytes (in hexadecimal).
+A patch is being written for XFree86 which will make this automatic:
+in other words the X server will manipulate /proc/mtrr using the
+ioctl() interface, so users won't have to do anything. If you use a
+commercial X server, lobby your vendor to add support for MTRRs.
+
+
+Creating overlapping MTRRs
+==========================
+::
+
+  %echo "base=0xfb000000 size=0x1000000 type=write-combining" >/proc/mtrr
+  %echo "base=0xfb000000 size=0x1000 type=uncachable" >/proc/mtrr
+
+And the results::
+
+  % cat /proc/mtrr
+  reg00: base=0x00000000 (   0MB), size=  64MB: write-back, count=1
+  reg01: base=0xfb000000 (4016MB), size=  16MB: write-combining, count=1
+  reg02: base=0xfb000000 (4016MB), size=   4kB: uncachable, count=1
+
+Some cards (especially Voodoo Graphics boards) need this 4 kB area
+excluded from the beginning of the region because it is used for
+registers.
+
+NOTE: You can only create type=uncachable region, if the first
+region that you created is type=write-combining.
+
+
+Removing MTRRs from the C-shel
+==============================
+::
+
+  % echo "disable=2" >! /proc/mtrr
+
+or using bash::
+
+  % echo "disable=2" >| /proc/mtrr
+
+
+Reading MTRRs from a C program using ioctl()'s

-Phasing out MTRR use
-
-MTRR use is replaced on modern x86 hardware with PAT. Direct MTRR use by
-drivers on Linux is now completely phased out, device drivers should use
-arch_phys_wc_add() in combination with ioremap_wc() to make MTRR effective on
-non-PAT systems while a no-op but equally effective on PAT enabled systems.
-
-Even if Linux does not use MTRRs directly, some x86 platform firmware may still
-set up MTRRs early before booting the OS. They do this as some platform
-firmware may still have implemented access to MTRRs which would be controlled
-and handled by the platform firmware directly. An example of platform use of
-MTRRs is through the use of SMI handlers, one case could be for fan control,
-the platform code would need uncachable access to some of its fan control
-registers. Such platform access does not need any Operating System MTRR code in
-place other than mtrr_type_lookup() to ensure any OS specific mapping requests
-are aligned with platform MTRR setup. If MTRRs are only set up by the platform
-firmware code though and the OS does not make any specific MTRR mapping
-requests mtrr_type_lookup() should always return MTRR_TYPE_INVALID.
-
-For details refer to Documentation/x86/pat.txt.
-
-===============================================================================
-
-  On Intel P6 family processors (Pentium Pro, Pentium II and later)
-  the Memory Type Range Registers (MTRRs) may be used to control
-  processor access to memory ranges. This is most useful when you have
-  a video (VGA) card on a PCI or AGP bus. Enabling write-combining
-  allows bus write transfers to be combined into a larger transfer
-  before bursting over the PCI/AGP bus. This can increase performance
-  of image write operations 2.5 times or more.
-
-  The Cyrix 6x86, 6x86MX and M II processors have Address Range
-  Registers (ARRs) which provide a similar functionality to MTRRs. For
-  these, the ARRs are used to emulate the MTRRs.
-
-  The AMD K6-2 (stepping 8 and above) and K6-3 processors have two
-  MTRRs. These are supported.  The AMD Athlon family provide 8 Intel
-  style MTRRs.
-
-  The Centaur C6 (WinChip) has 8 MCRs, allowing write-combining. These
-  are supported.
-
-  The VIA Cyrix III and VIA C3 CPUs offer 8 Intel style MTRRs.
-
-  The CONFIG_MTRR option creates a /proc/mtrr file which may be used
-  to manipulate your MTRRs. Typically the X server should use
-  this. This should have a reasonably generic interface so that
-  similar control registers on other processors can be easily
-  supported.
-
-
-There are two interfaces to /proc/mtrr: one is an ASCII interface
-which allows you to read and write. The other is an ioctl()
-interface. The ASCII interface is meant for administration. The
-ioctl() interface is meant for C programs (i.e. the X server). The
-interfaces are described below, with sample commands and C code.
-
-===============================================================================
-Reading MTRRs from the shell:
-
-% cat /proc/mtrr
-reg00: base=0x00000000 (   0MB), size= 128MB: write-back, count=1
-reg01: base=0x08000000 ( 128MB), size=  64MB: write-back, count=1
-===============================================================================
-Creating MTRRs from the C-shell:
-# echo "base=0xf8000000 size=0x400000 type=write-combining" >! /proc/mtrr
-or if you use bash:
-# echo "base=0xf8000000 size=0x400000 type=write-combining" >| /proc/mtrr
-
-And the result thereof:
-% cat /proc/mtrr
-reg00: base=0x00000000 (   0MB), size= 128MB: write-back, count=1
-reg01: base=0x08000000 ( 128MB), size=  64MB: write-back, count=1
-reg02: base=0xf8000000 (3968MB), size=   4MB: write-combining, count=1
-
-This is for video RAM at base address 0xf8000000 and size 4 megabytes. To
-find out your base address, you need to look at the output of your X
-server, which tells you where the linear framebuffer address is. A
-typical line that you may get is:
-
-(--) S3: PCI: 968 rev 0, Linear FB @ 0xf8000000
-
-Note that you should only use the value from the X server, as it may
-move the framebuffer base address, so the only value you can trust is
-that reported by the X server.
-
-To find out the size of your framebuffer (what, you don't actually
-know?), the following line will tell you:
-
-(--) S3: videoram:  4096k
-
-That's 4 megabytes, which is 0x400000 bytes (in hexadecimal).
-A patch is being written for XFree86 which will make this automatic:
-in other words the X server will manipulate /proc/mtrr using the
-ioctl() interface, so users won't have to do anything. If you use a
-commercial X server, lobby your vendor to add support for MTRRs.
-===============================================================================
-Creating overlapping MTRRs:
-
-%echo "base=0xfb000000 size=0x1000000 type=write-combining" >/proc/mtrr
-%echo "base=0xfb000000 size=0x1000 type=uncachable" >/proc/mtrr
-
-And the results: cat /proc/mtrr
-reg00: base=0x00000000 (   0MB), size=  64MB: write-back, count=1
-reg01: base=0xfb000000 (4016MB), size=  16MB: write-combining, count=1
-reg02: base=0xfb000000 (4016MB), size=   4kB: uncachable, count=1
-
-Some cards (especially Voodoo Graphics boards) need this 4 kB area
-excluded from the beginning of the region because it is used for
-registers.
-
-NOTE: You can only create type=uncachable region, if the first
-region that you created is type=write-combining.
-===============================================================================
-Removing MTRRs from the C-shell:
-% echo "disable=2" >! /proc/mtrr
-or using bash:
-% echo "disable=2" >| /proc/mtrr

+ORC unwinder
+============
+
+Overview
+========
+
+The kernel CONFIG_UNWINDER_ORC option enables the ORC unwinder, which is
+similar in concept to a DWARF unwinder.  The difference is that the
+format of the ORC data is much simpler than DWARF, which in turn allows
+the ORC unwinder to be much simpler and faster.
+
+The ORC data consists of unwind tables which are generated by objtool.
+They contain out-of-band data which is used by the in-kernel ORC
+unwinder.  Objtool generates the ORC data by first doing compile-time
+stack metadata validation (CONFIG_STACK_VALIDATION).  After analyzing
+all the code paths of a .o file, it determines information about the
+stack state at each instruction address in the file and outputs that
+information to the .orc_unwind and .orc_unwind_ip sections.
+
+The per-object ORC sections are combined at link time and are sorted and
+post-processed at boot time.  The unwinder uses the resulting data to
+correlate instruction addresses with their stack states at run time.
+
+
+ORC vs frame pointers
+=====================
+
+With frame pointers enabled, GCC adds instrumentation code to every
+function in the kernel.  The kernel's .text size increases by about
+3.2%, resulting in a broad kernel-wide slowdown.  Measurements by Mel
+Gorman [1]_ have shown a slowdown of 5-10% for some workloads.
+
+In contrast, the ORC unwinder has no effect on text size or runtime
+performance, because the debuginfo is out of band.  So if you disable
+frame pointers and enable the ORC unwinder, you get a nice performance
+improvement across the board, and still have reliable stack traces.
+
+Ingo Molnar says:
+
+  "Note that it's not just a performance improvement, but also an
+  instruction cache locality improvement: 3.2% .text savings almost
+  directly transform into a similarly sized reduction in cache
+  footprint. That can transform to even higher speedups for workloads
+  whose cache locality is borderline."
+
+Another benefit of ORC compared to frame pointers is that it can
+reliably unwind across interrupts and exceptions.  Frame pointer based
+unwinds can sometimes skip the caller of the interrupted function, if it
+was a leaf function or if the interrupt hit before the frame pointer was
+saved.
+
+The main disadvantage of the ORC unwinder compared to frame pointers is
+that it needs more memory to store the ORC unwind tables: roughly 2-4MB
+depending on the kernel config.
+
+
+ORC vs DWARF
+============
+
+ORC debuginfo's advantage over DWARF itself is that it's much simpler.
+It gets rid of the complex DWARF CFI state machine and also gets rid of
+the tracking of unnecessary registers.  This allows the unwinder to be
+much simpler, meaning fewer bugs, which is especially important for
+mission critical oops code.
+
+The simpler debuginfo format also enables the unwinder to be much faster
+than DWARF, which is important for perf and lockdep.  In a basic
+performance test by Jiri Slaby [2]_, the ORC unwinder was about 20x
+faster than an out-of-tree DWARF unwinder.  (Note: That measurement was
+taken before some performance tweaks were added, which doubled
+performance, so the speedup over DWARF may be closer to 40x.)
+
+The ORC data format does have a few downsides compared to DWARF.  ORC
+unwind tables take up ~50% more RAM (+1.3MB on an x86 defconfig kernel)
+than DWARF-based eh_frame tables.
+
+Another potential downside is that, as GCC evolves, it's conceivable
+that the ORC data may end up being *too* simple to describe the state of
+the stack for certain optimizations.  But IMO this is unlikely because
+GCC saves the frame pointer for any unusual stack adjustments it does,
+so I suspect we'll really only ever need to keep track of the stack
+pointer and the frame pointer between call frames.  But even if we do
+end up having to track all the registers DWARF tracks, at least we will
+still be able to control the format, e.g. no complex state machines.
+
+
+ORC unwind table generation
+===========================
+
+The ORC data is generated by objtool.  With the existing compile-time
+stack metadata validation feature, objtool already follows all code
+paths, and so it already has all the information it needs to be able to
+generate ORC data from scratch.  So it's an easy step to go from stack
+validation to ORC data generation.
+
+It should be possible to instead generate the ORC data with a simple
+tool which converts DWARF to ORC data.  However, such a solution would
+be incomplete due to the kernel's extensive use of asm, inline asm, and
+special sections like exception tables.
+
+That could be rectified by manually annotating those special code paths
+using GNU assembler .cfi annotations in .S files, and homegrown
+annotations for inline asm in .c files.  But asm annotations were tried
+in the past and were found to be unmaintainable.  They were often
+incorrect/incomplete and made the code harder to read and keep updated.
+And based on looking at glibc code, annotating inline asm in .c files
+might be even worse.
+
+Objtool still needs a few annotations, but only in code which does
+unusual things to the stack like entry code.  And even then, far fewer
+annotations are needed than what DWARF would need, so they're much more
+maintainable than DWARF CFI annotations.
+
+So the advantages of using objtool to generate ORC data are that it
+gives more accurate debuginfo, with very few annotations.  It also
+insulates the kernel from toolchain bugs which can be very painful to
+deal with in the kernel since we often have to workaround issues in
+older versions of the toolchain for years.
+
+The downside is that the unwinder now becomes dependent on objtool's
+ability to reverse engineer GCC code flow.  If GCC optimizations become
+too complicated for objtool to follow, the ORC data generation might
+stop working or become incomplete.  (It's worth noting that livepatch
+already has such a dependency on objtool's ability to follow GCC code
+flow.)
+
+If newer versions of GCC come up with some optimizations which break
+objtool, we may need to revisit the current implementation.  Some
+possible solutions would be asking GCC to make the optimizations more
+palatable, or having objtool use DWARF as an additional input, or
+creating a GCC plugin to assist objtool with its analysis.  But for now,
+objtool follows GCC code quite well.
+
+
+Unwinder implementation details
+===============================
+
+Objtool generates the ORC data by integrating with the compile-time
+stack metadata validation feature, which is described in detail in
+tools/objtool/Documentation/stack-validation.txt.  After analyzing all
+the code paths of a .o file, it creates an array of orc_entry structs,
+and a parallel array of instruction addresses associated with those
+structs, and writes them to the .orc_unwind and .orc_unwind_ip sections
+respectively.
+
+The ORC data is split into the two arrays for performance reasons, to
+make the searchable part of the data (.orc_unwind_ip) more compact.  The
+arrays are sorted in parallel at boot time.
+
+Performance is further improved by the use of a fast lookup table which
+is created at runtime.  The fast lookup table associates a given address
+with a range of indices for the .orc_unwind table, so that only a small
+subset of the table needs to be searched.
+
+
+Etymology
+=========
+
+Orcs, fearsome creatures of medieval folklore, are the Dwarves' natural
+enemies.  Similarly, the ORC unwinder was created in opposition to the
+complexity and slowness of DWARF.
+
+"Although Orcs rarely consider multiple solutions to a problem, they do
+excel at getting things done because they are creatures of action, not
+thought." [3]_  Similarly, unlike the esoteric DWARF unwinder, the
+veracious ORC unwinder wastes no time or siloconic effort decoding
+variable-length zero-extended unsigned-integer byte-coded
+state-machine-based debug information entries.
+
+Similar to how Orcs frequently unravel the well-intentioned plans of
+their adversaries, the ORC unwinder frequently unravels stacks with
+brutal, unyielding efficiency.
+
+ORC stands for Oops Rewind Capability.

-In contrast, the ORC unwinder has no effect on text size or runtime
-performance, because the debuginfo is out of band.  So if you disable
-frame pointers and enable the ORC unwinder, you get a nice performance
-improvement across the board, and still have reliable stack traces.
-
-Ingo Molnar says:
-
-  "Note that it's not just a performance improvement, but also an
-  instruction cache locality improvement: 3.2% .text savings almost
-  directly transform into a similarly sized reduction in cache
-  footprint. That can transform to even higher speedups for workloads
-  whose cache locality is borderline."
-
-Another benefit of ORC compared to frame pointers is that it can
-reliably unwind across interrupts and exceptions.  Frame pointer based
-unwinds can sometimes skip the caller of the interrupted function, if it
-was a leaf function or if the interrupt hit before the frame pointer was
-saved.
-
-The main disadvantage of the ORC unwinder compared to frame pointers is
-that it needs more memory to store the ORC unwind tables: roughly 2-4MB
-depending on the kernel config.
-
-
-ORC vs DWARF
-------------
-
-ORC debuginfo's advantage over DWARF itself is that it's much simpler.
-It gets rid of the complex DWARF CFI state machine and also gets rid of
-the tracking of unnecessary registers.  This allows the unwinder to be
-much simpler, meaning fewer bugs, which is especially important for
-mission critical oops code.
-
-The simpler debuginfo format also enables the unwinder to be much faster
-than DWARF, which is important for perf and lockdep.  In a basic
-performance test by Jiri Slaby [2], the ORC unwinder was about 20x
-faster than an out-of-tree DWARF unwinder.  (Note: That measurement was
-taken before some performance tweaks were added, which doubled
-performance, so the speedup over DWARF may be closer to 40x.)
-
-The ORC data format does have a few downsides compared to DWARF.  ORC
-unwind tables take up ~50% more RAM (+1.3MB on an x86 defconfig kernel)
-than DWARF-based eh_frame tables.
-
-Another potential downside is that, as GCC evolves, it's conceivable
-that the ORC data may end up being *too* simple to describe the state of
-the stack for certain optimizations.  But IMO this is unlikely because
-GCC saves the frame pointer for any unusual stack adjustments it does,
-so I suspect we'll really only ever need to keep track of the stack
-pointer and the frame pointer between call frames.  But even if we do
-end up having to track all the registers DWARF tracks, at least we will
-still be able to control the format, e.g. no complex state machines.
-
-
-ORC unwind table generation
----------------------------
-
-The ORC data is generated by objtool.  With the existing compile-time
-stack metadata validation feature, objtool already follows all code
-paths, and so it already has all the information it needs to be able to
-generate ORC data from scratch.  So it's an easy step to go from stack
-validation to ORC data generation.
-
-It should be possible to instead generate the ORC data with a simple
-tool which converts DWARF to ORC data.  However, such a solution would
-be incomplete due to the kernel's extensive use of asm, inline asm, and
-special sections like exception tables.
-
-That could be rectified by manually annotating those special code paths
-using GNU assembler .cfi annotations in .S files, and homegrown
-annotations for inline asm in .c files.  But asm annotations were tried
-in the past and were found to be unmaintainable.  They were often
-incorrect/incomplete and made the code harder to read and keep updated.
-And based on looking at glibc code, annotating inline asm in .c files
-might be even worse.
-
-Objtool still needs a few annotations, but only in code which does
-unusual things to the stack like entry code.  And even then, far fewer
-annotations are needed than what DWARF would need, so they're much more
-maintainable than DWARF CFI annotations.
-
-So the advantages of using objtool to generate ORC data are that it
-gives more accurate debuginfo, with very few annotations.  It also
-insulates the kernel from toolchain bugs which can be very painful to
-deal with in the kernel since we often have to workaround issues in
-older versions of the toolchain for years.
-
-The downside is that the unwinder now becomes dependent on objtool's
-ability to reverse engineer GCC code flow.  If GCC optimizations become
-too complicated for objtool to follow, the ORC data generation might
-stop working or become incomplete.  (It's worth noting that livepatch
-already has such a dependency on objtool's ability to follow GCC code
-flow.)
-
-If newer versions of GCC come up with some optimizations which break
-objtool, we may need to revisit the current implementation.  Some
-possible solutions would be asking GCC to make the optimizations more
-palatable, or having objtool use DWARF as an additional input, or
-creating a GCC plugin to assist objtool with its analysis.  But for now,
-objtool follows GCC code quite well.
-
-
-Unwinder implementation details
--------------------------------
-
-Objtool generates the ORC data by integrating with the compile-time
-stack metadata validation feature, which is described in detail in
-tools/objtool/Documentation/stack-validation.txt.  After analyzing all
-the code paths of a .o file, it creates an array of orc_entry structs,
-and a parallel array of instruction addresses associated with those
-structs, and writes them to the .orc_unwind and .orc_unwind_ip sections
-respectively.
-
-The ORC data is split into the two arrays for performance reasons, to
-make the searchable part of the data (.orc_unwind_ip) more compact.  The
-arrays are sorted in parallel at boot time.
-
-Performance is further improved by the use of a fast lookup table which
-is created at runtime.  The fast lookup table associates a given address
-with a range of indices for the .orc_unwind table, so that only a small
-subset of the table needs to be searched.
-
-
-Etymology
----------
-
-Orcs, fearsome creatures of medieval folklore, are the Dwarves' natural
-enemies.  Similarly, the ORC unwinder was created in opposition to the
-complexity and slowness of DWARF.
-
-"Although Orcs rarely consider multiple solutions to a problem, they do
-excel at getting things done because they are creatures of action, not
-thought." [3]  Similarly, unlike the esoteric DWARF unwinder, the
-veracious ORC unwinder wastes no time or siloconic effort decoding
-variable-length zero-extended unsigned-integer byte-coded
-state-machine-based debug information entries.
-
-Similar to how Orcs frequently unravel the well-intentioned plans of
-their adversaries, the ORC unwinder frequently unravels stacks with
-brutal, unyielding efficiency.
-
-ORC stands for Oops Rewind Capability.

+Advanced APIs for drivers
+=========================
+
+A. Exporting pages to users with remap_pfn_range, io_remap_pfn_range,
+vmf_insert_pfn.
+
+Drivers wanting to export some pages to userspace do it by using mmap
+interface and a combination of:
+
+  1) pgprot_noncached()
+  2) io_remap_pfn_range() or remap_pfn_range() or vmf_insert_pfn()
+
+With PAT support, a new API pgprot_writecombine is being added. So, drivers can
+continue to use the above sequence, with either pgprot_noncached() or
+pgprot_writecombine() in step 1, followed by step 2.
+
+In addition, step 2 internally tracks the region as UC or WC in memtype
+list in order to ensure no conflicting mapping.
+
+Note that this set of APIs only works with IO (non RAM) regions. If driver
+wants to export a RAM region, it has to do set_memory_uc() or set_memory_wc()
+as step 0 above and also track the usage of those pages and use set_memory_wb()
+before the page is freed to free pool.
+
+MTRR effects on PAT / non-PAT systems
+=====================================
+
+The following table provides the effects of using write-combining MTRRs when
+using ioremap*() calls on x86 for both non-PAT and PAT systems. Ideally
+mtrr_add() usage will be phased out in favor of arch_phys_wc_add() which will
+be a no-op on PAT enabled systems. The region over which a arch_phys_wc_add()
+is made, should already have been ioremapped with WC attributes or PAT entries,
+this can be done by using ioremap_wc() / set_memory_wc().  Devices which
+combine areas of IO memory desired to remain uncacheable with areas where
+write-combining is desirable should consider use of ioremap_uc() followed by
+set_memory_wc() to white-list effective write-combined areas.  Such use is
+nevertheless discouraged as the effective memory type is considered
+implementation defined, yet this strategy can be used as last resort on devices
+with size-constrained regions where otherwise MTRR write-combining would
+otherwise not be effective.

+
+For ioremap and pci access through /sys or /proc - The actual type returned
+can be more restrictive, in case of any existing aliasing for that address.
+For example: If there is an existing uncached mapping, a new ioremap_wc can

+
+set_memory_[uc|wc|wt] and set_memory_wb should be used in pairs, where driver
+will first make a region uc, wc or wt and switch it back to wb after use.
+
+Over time writes to /proc/mtrr will be deprecated in favor of using PAT based
+interfaces. Users writing to /proc/mtrr are suggested to use above interfaces.
+
+Drivers should use ioremap_[uc|wc] to access PCI BARs with [uc|wc] access
+types.
+
+Drivers should use set_memory_[uc|wc|wt] to set access type for RAM ranges.

+PAT debugging

-Advanced APIs for drivers
--------------------------
-A. Exporting pages to users with remap_pfn_range, io_remap_pfn_range,
-vmf_insert_pfn
-
-Drivers wanting to export some pages to userspace do it by using mmap
-interface and a combination of
-1) pgprot_noncached()
-2) io_remap_pfn_range() or remap_pfn_range() or vmf_insert_pfn()
-
-With PAT support, a new API pgprot_writecombine is being added. So, drivers can
-continue to use the above sequence, with either pgprot_noncached() or
-pgprot_writecombine() in step 1, followed by step 2.
-
-In addition, step 2 internally tracks the region as UC or WC in memtype
-list in order to ensure no conflicting mapping.
-
-Note that this set of APIs only works with IO (non RAM) regions. If driver
-wants to export a RAM region, it has to do set_memory_uc() or set_memory_wc()
-as step 0 above and also track the usage of those pages and use set_memory_wb()
-before the page is freed to free pool.
-
-MTRR effects on PAT / non-PAT systems
--------------------------------------
-
-The following table provides the effects of using write-combining MTRRs when
-using ioremap*() calls on x86 for both non-PAT and PAT systems. Ideally
-mtrr_add() usage will be phased out in favor of arch_phys_wc_add() which will
-be a no-op on PAT enabled systems. The region over which a arch_phys_wc_add()
-is made, should already have been ioremapped with WC attributes or PAT entries,
-this can be done by using ioremap_wc() / set_memory_wc().  Devices which
-combine areas of IO memory desired to remain uncacheable with areas where
-write-combining is desirable should consider use of ioremap_uc() followed by
-set_memory_wc() to white-list effective write-combined areas.  Such use is
-nevertheless discouraged as the effective memory type is considered
-implementation defined, yet this strategy can be used as last resort on devices
-with size-constrained regions where otherwise MTRR write-combining would
-otherwise not be effective.

-Notes:
-
--- in the above table mean "Not suggested usage for the API". Some of the --'s
-are strictly enforced by the kernel. Some others are not really enforced
-today, but may be enforced in future.
-
-For ioremap and pci access through /sys or /proc - The actual type returned
-can be more restrictive, in case of any existing aliasing for that address.
-For example: If there is an existing uncached mapping, a new ioremap_wc can
-return uncached mapping in place of write-combine requested.
-
-set_memory_[uc|wc|wt] and set_memory_wb should be used in pairs, where driver
-will first make a region uc, wc or wt and switch it back to wb after use.
-
-Over time writes to /proc/mtrr will be deprecated in favor of using PAT based
-interfaces. Users writing to /proc/mtrr are suggested to use above interfaces.
-
-Drivers should use ioremap_[uc|wc] to access PCI BARs with [uc|wc] access
-types.
-
-Drivers should use set_memory_[uc|wc|wt] to set access type for RAM ranges.

-PAT debugging
--------------
-
-With CONFIG_DEBUG_FS enabled, PAT memtype list can be examined by
-
-# mount -t debugfs debugfs /sys/kernel/debug
-# cat /sys/kernel/debug/x86/pat_memtype_list
-PAT memtype list:
-uncached-minus @ 0x7fadf000-0x7fae0000
-uncached-minus @ 0x7fb19000-0x7fb1a000
-uncached-minus @ 0x7fb1a000-0x7fb1b000

-uncached-minus @ 0x7fb31000-0x7fb32000
-uncached-minus @ 0x80000000-0x90000000
-
-This list shows physical address ranges and various PAT settings used to
-access those physical address ranges.
-
-Another, more verbose way of getting PAT related debug messages is with
-"debugpat" boot parameter. With this parameter, various debug messages are
-printed to dmesg log.
-
-PAT Initialization
-------------------
-
-The following table describes how PAT is initialized under various
-configurations. The PAT MSR must be updated by Linux in order to support WC
-and WT attributes. Otherwise, the PAT MSR has the value programmed in it
-by the firmware. Note, Xen enables WC attribute in the PAT MSR for guests.

+Memory Protection Keys
+======================
+
+Memory Protection Keys for Userspace (PKU aka PKEYs) is a feature
+which is found on Intel's Skylake "Scalable Processor" Server CPUs.
+It will be avalable in future non-server parts.
+
+For anyone wishing to test or use this feature, it is available in
+Amazon's EC2 C5 instances and is known to work there using an Ubuntu
+17.04 image.
+
+Memory Protection Keys provides a mechanism for enforcing page-based
+protections, but without requiring modification of the page tables
+when an application changes protection domains.  It works by
+dedicating 4 previously ignored bits in each page table entry to a
+"protection key", giving 16 possible keys.
+
+There is also a new user-accessible register (PKRU) with two separate
+bits (Access Disable and Write Disable) for each key.  Being a CPU
+register, PKRU is inherently thread-local, potentially giving each
+thread a different set of protections from every other thread.
+
+There are two new instructions (RDPKRU/WRPKRU) for reading and writing
+to the new register.  The feature is only available in 64-bit mode,
+even though there is theoretically space in the PAE PTEs.  These
+permissions are enforced on data access only and have no effect on
+instruction fetches.
+
+Syscalls
+========
+
+There are 3 system calls which directly interact with pkeys::
+
+	int pkey_alloc(unsigned long flags, unsigned long init_access_rights)
+	int pkey_free(int pkey);
+	int pkey_mprotect(unsigned long start, size_t len,
+			  unsigned long prot, int pkey);
+
+Before a pkey can be used, it must first be allocated with
+pkey_alloc().  An application calls the WRPKRU instruction
+directly in order to change access permissions to memory covered
+with a key.  In this example WRPKRU is wrapped by a C function
+called pkey_set().
+::
+
+	int real_prot = PROT_READ|PROT_WRITE;
+	pkey = pkey_alloc(0, PKEY_DISABLE_WRITE);
+	ptr = mmap(NULL, PAGE_SIZE, PROT_NONE, MAP_ANONYMOUS|MAP_PRIVATE, -1, 0);
+	ret = pkey_mprotect(ptr, PAGE_SIZE, real_prot, pkey);
+	... application runs here
+
+Now, if the application needs to update the data at 'ptr', it can
+gain access, do the update, then remove its write access::
+
+	pkey_set(pkey, 0); // clear PKEY_DISABLE_WRITE
+	*ptr = foo; // assign something
+	pkey_set(pkey, PKEY_DISABLE_WRITE); // set PKEY_DISABLE_WRITE again
+
+Now when it frees the memory, it will also free the pkey since it
+is no longer in use::
+
+	munmap(ptr, PAGE_SIZE);
+	pkey_free(pkey);
+
+.. note:: pkey_set() is a wrapper for the RDPKRU and WRPKRU instructions.
+          An example implementation can be found in
+          tools/testing/selftests/x86/protection_keys.c.
+
+Behavior
+========
+
+The kernel attempts to make protection keys consistent with the
+behavior of a plain mprotect().  For instance if you do this::
+
+	mprotect(ptr, size, PROT_NONE);
+	something(ptr);
+
+you can expect the same effects with protection keys when doing this::
+
+	pkey = pkey_alloc(0, PKEY_DISABLE_WRITE | PKEY_DISABLE_READ);
+	pkey_mprotect(ptr, size, PROT_READ|PROT_WRITE, pkey);
+	something(ptr);
+
+That should be true whether something() is a direct access to 'ptr'
+like::
+
+	*ptr = foo;
+
+or when the kernel does the access on the application's behalf like
+with a read()::
+
+	read(fd, ptr, 1);
+
+The kernel will send a SIGSEGV in both cases, but si_code will be set
+to SEGV_PKERR when violating protection keys versus SEGV_ACCERR when
+the plain mprotect() permissions are violated.

+Page Table Isolation (PTI)
+==========================
+
+Overview
+========
+
+Page Table Isolation (pti, previously known as KAISER [1]_) is a
+countermeasure against attacks on the shared user/kernel address
+space such as the "Meltdown" approach [2]_.
+
+To mitigate this class of attacks, we create an independent set of
+page tables for use only when running userspace applications.  When
+the kernel is entered via syscalls, interrupts or exceptions, the
+page tables are switched to the full "kernel" copy.  When the system
+switches back to user mode, the user copy is used again.
+
+The userspace page tables contain only a minimal amount of kernel
+data: only what is needed to enter/exit the kernel such as the
+entry/exit functions themselves and the interrupt descriptor table
+(IDT).  There are a few strictly unnecessary things that get mapped
+such as the first C function when entering an interrupt (see
+comments in pti.c).
+
+This approach helps to ensure that side-channel attacks leveraging
+the paging structures do not function when PTI is enabled.  It can be
+enabled by setting CONFIG_PAGE_TABLE_ISOLATION=y at compile time.
+Once enabled at compile-time, it can be disabled at boot with the
+'nopti' or 'pti=' kernel parameters (see kernel-parameters.txt).
+
+Page Table Management
+=====================
+
+When PTI is enabled, the kernel manages two sets of page tables.
+The first set is very similar to the single set which is present in
+kernels without PTI.  This includes a complete mapping of userspace
+that the kernel can use for things like copy_to_user().
+
+Although _complete_, the user portion of the kernel page tables is
+crippled by setting the NX bit in the top level.  This ensures
+that any missed kernel->user CR3 switch will immediately crash
+userspace upon executing its first instruction.
+
+The userspace page tables map only the kernel data needed to enter
+and exit the kernel.  This data is entirely contained in the 'struct
+cpu_entry_area' structure which is placed in the fixmap which gives
+each CPU's copy of the area a compile-time-fixed virtual address.
+
+For new userspace mappings, the kernel makes the entries in its
+page tables like normal.  The only difference is when the kernel
+makes entries in the top (PGD) level.  In addition to setting the
+entry in the main kernel PGD, a copy of the entry is made in the
+userspace page tables' PGD.
+
+This sharing at the PGD level also inherently shares all the lower
+layers of the page tables.  This leaves a single, shared set of
+userspace page tables to manage.  One PTE to lock, one set of
+accessed bits, dirty bits, etc...
+
+Overhead
+========
+
+Protection against side-channel attacks is important.  But,
+this protection comes at a cost:
+
+1. Increased Memory Use
+
+  a. Each process now needs an order-1 PGD instead of order-0.
+     (Consumes an additional 4k per process).
+  b. The 'cpu_entry_area' structure must be 2MB in size and 2MB
+     aligned so that it can be mapped by setting a single PMD
+     entry.  This consumes nearly 2MB of RAM once the kernel
+     is decompressed, but no space in the kernel image itself.
+
+2. Runtime Cost
+
+  a. CR3 manipulation to switch between the page table copies
+     must be done at interrupt, syscall, and exception entry
+     and exit (it can be skipped when the kernel is interrupted,
+     though.)  Moves to CR3 are on the order of a hundred
+     cycles, and are required at every entry and exit.
+  b. A "trampoline" must be used for SYSCALL entry.  This
+     trampoline depends on a smaller set of resources than the
+     non-PTI SYSCALL entry code, so requires mapping fewer
+     things into the userspace page tables.  The downside is
+     that stacks must be switched at entry time.
+  c. Global pages are disabled for all kernel structures not
+     mapped into both kernel and userspace page tables.  This
+     feature of the MMU allows different processes to share TLB
+     entries mapping the kernel.  Losing the feature means more
+     TLB misses after a context switch.  The actual loss of
+     performance is very small, however, never exceeding 1%.
+  d. Process Context IDentifiers (PCID) is a CPU feature that
+     allows us to skip flushing the entire TLB when switching page
+     tables by setting a special bit in CR3 when the page tables
+     are changed.  This makes switching the page tables (at context
+     switch, or kernel entry/exit) cheaper.  But, on systems with
+     PCID support, the context switch code must flush both the user
+     and kernel entries out of the TLB.  The user PCID TLB flush is
+     deferred until the exit to userspace, minimizing the cost.
+     See intel.com/sdm for the gory PCID/INVPCID details.
+  e. The userspace page tables must be populated for each new
+     process.  Even without PTI, the shared kernel mappings
+     are created by copying top-level (PGD) entries into each
+     new process.  But, with PTI, there are now *two* kernel
+     mappings: one in the kernel page tables that maps everything
+     and one for the entry/exit structures.  At fork(), we need to
+     copy both.
+  f. In addition to the fork()-time copying, there must also
+     be an update to the userspace PGD any time a set_pgd() is done
+     on a PGD used to map userspace.  This ensures that the kernel
+     and userspace copies always map the same userspace
+     memory.
+  g. On systems without PCID support, each CR3 write flushes
+     the entire TLB.  That means that each syscall, interrupt
+     or exception flushes the TLB.
+  h. INVPCID is a TLB-flushing instruction which allows flushing
+     of TLB entries for non-current PCIDs.  Some systems support
+     PCIDs, but do not support INVPCID.  On these systems, addresses
+     can only be flushed from the TLB for the current PCID.  When
+     flushing a kernel address, we need to flush all PCIDs, so a
+     single kernel address flush will require a TLB-flushing CR3
+     write upon the next use of every PCID.
+
+Possible Future Work
+====================
+1. We can be more careful about not actually writing to CR3
+   unless its value is actually changed.
+2. Allow PTI to be enabled/disabled at runtime in addition to the
+   boot-time switching.
+
+Testing
+========
+
+To test stability of PTI, the following test procedure is recommended,
+ideally doing all of these in parallel:
+
+1. Set CONFIG_DEBUG_ENTRY=y
+2. Run several copies of all of the tools/testing/selftests/x86/ tests
+   (excluding MPX and protection_keys) in a loop on multiple CPUs for
+   several minutes.  These tests frequently uncover corner cases in the
+   kernel entry code.  In general, old kernels might cause these tests
+   themselves to crash, but they should never crash the kernel.
+3. Run the 'perf' tool in a mode (top or record) that generates many
+   frequent performance monitoring non-maskable interrupts (see "NMI"
+   in /proc/interrupts).  This exercises the NMI entry/exit code which
+   is known to trigger bugs in code paths that did not expect to be
+   interrupted, including nested NMIs.  Using "-c" boosts the rate of
+   NMIs, and using two -c with separate counters encourages nested NMIs
+   and less deterministic behavior.
+   ::
+
+	while true; do perf record -c 10000 -e instructions,cycles -a sleep 10; done
+
+4. Launch a KVM virtual machine.
+5. Run 32-bit binaries on systems supporting the SYSCALL instruction.
+   This has been a lightly-tested code path and needs extra scrutiny.
+
+Debugging
+=========
+
+Bugs in PTI cause a few different signatures of crashes
+that are worth noting here.
+
+ * Failures of the selftests/x86 code.  Usually a bug in one of the
+   more obscure corners of entry_64.S
+ * Crashes in early boot, especially around CPU bringup.  Bugs
+   in the trampoline code or mappings cause these.
+ * Crashes at the first interrupt.  Caused by bugs in entry_64.S,
+   like screwing up a page table switch.  Also caused by
+   incorrectly mapping the IRQ handler entry code.
+ * Crashes at the first NMI.  The NMI code is separate from main
+   interrupt handlers and can have bugs that do not affect
+   normal interrupts.  Also caused by incorrectly mapping NMI
+   code.  NMIs that interrupt the entry code must be very
+   careful and can be the cause of crashes that show up when
+   running perf.
+ * Kernel crashes at the first exit to userspace.  entry_64.S
+   bugs, or failing to map some of the exit code.
+ * Crashes at first interrupt that interrupts userspace. The paths
+   in entry_64.S that return to userspace are sometimes separate
+   from the ones that return to the kernel.
+ * Double faults: overflowing the kernel stack because of page
+   faults upon page faults.  Caused by touching non-pti-mapped
+   data in the entry code, or forgetting to switch to kernel
+   CR3 before calling into C functions which are not pti-mapped.
+ * Userspace segfaults early in boot, sometimes manifesting
+   as mount(8) failing to mount the rootfs.  These have
+   tended to be TLB invalidation issues.  Usually invalidating
+   the wrong PCID, or otherwise missing an invalidation.

+
+
+Intel refers to this feature as Intel Resource Director Technology(Intel(R) RDT).
+AMD refers to this feature as AMD Platform Quality of Service(AMD QoS).
+
+This feature is enabled by the CONFIG_X86_CPU_RESCTRL and the x86 /proc/cpuinfo
+flag bits:
+
+=============================================	================================
+RDT (Resource Director Technology) Allocation	"rdt_a"
+CAT (Cache Allocation Technology)		"cat_l3", "cat_l2"
+CDP (Code and Data Prioritization)		"cdp_l3", "cdp_l2"
+CQM (Cache QoS Monitoring)			"cqm_llc", "cqm_occup_llc"
+MBM (Memory Bandwidth Monitoring)		"cqm_mbm_total", "cqm_mbm_local"
+MBA (Memory Bandwidth Allocation)		"mba"
+=============================================	================================
+
+To use the feature mount the file system::
+
+ # mount -t resctrl resctrl [-o cdp[,cdpl2][,mba_MBps]] /sys/fs/resctrl
+
+mount options are:
+
+"cdp":
+	Enable code/data prioritization in L3 cache allocations.
+"cdpl2":
+	Enable code/data prioritization in L2 cache allocations.
+"mba_MBps":
+	Enable the MBA Software Controller(mba_sc) to specify MBA
+	bandwidth in MBps
+
+L2 and L3 CDP are controlled seperately.
+
+RDT features are orthogonal. A particular system may support only
+monitoring, only control, or both monitoring and control.  Cache
+pseudo-locking is a unique way of using cache control to "pin" or
+"lock" data in the cache. Details can be found in
+"Cache Pseudo-Locking".
+
+
+The mount succeeds if either of allocation or monitoring is present, but
+only those files and directories supported by the system will be created.
+For more details on the behavior of the interface during monitoring
+and allocation, see the "Resource alloc and monitor groups" section.
+
+Info directory
+==============
+
+The 'info' directory contains information about the enabled
+resources. Each resource has its own subdirectory. The subdirectory
+names reflect the resource names.
+
+Each subdirectory contains the following files with respect to
+allocation:
+
+Cache resource(L3/L2)  subdirectory contains the following files
+related to allocation:
+
+"num_closids":
+		The number of CLOSIDs which are valid for this
+		resource. The kernel uses the smallest number of
+		CLOSIDs of all enabled resources as limit.
+"cbm_mask":
+		The bitmask which is valid for this resource.
+		This mask is equivalent to 100%.
+"min_cbm_bits":
+		The minimum number of consecutive bits which
+		must be set when writing a mask.
+
+"shareable_bits":
+		Bitmask of shareable resource with other executing
+		entities (e.g. I/O). User can use this when
+		setting up exclusive cache partitions. Note that
+		some platforms support devices that have their
+		own settings for cache use which can over-ride
+		these bits.
+"bit_usage":
+		Annotated capacity bitmasks showing how all
+		instances of the resource are used. The legend is:
+
+			"0":
+			      Corresponding region is unused. When the system's
+			      resources have been allocated and a "0" is found
+			      in "bit_usage" it is a sign that resources are
+			      wasted.
+
+			"H":
+			      Corresponding region is used by hardware only
+			      but available for software use. If a resource
+			      has bits set in "shareable_bits" but not all
+			      of these bits appear in the resource groups'
+			      schematas then the bits appearing in
+			      "shareable_bits" but no resource group will
+			      be marked as "H".
+			"X":
+			      Corresponding region is available for sharing and
+			      used by hardware and software. These are the
+			      bits that appear in "shareable_bits" as
+			      well as a resource group's allocation.
+			"S":
+			      Corresponding region is used by software
+			      and available for sharing.
+			"E":
+			      Corresponding region is used exclusively by
+			      one resource group. No sharing allowed.
+			"P":
+			      Corresponding region is pseudo-locked. No
+			      sharing allowed.
+
+Memory bandwitdh(MB) subdirectory contains the following files
+with respect to allocation:
+
+"min_bandwidth":
+		The minimum memory bandwidth percentage which
+		user can request.
+
+"bandwidth_gran":
+		The granularity in which the memory bandwidth
+		percentage is allocated. The allocated
+		b/w percentage is rounded off to the next
+		control step available on the hardware. The
+		available bandwidth control steps are:
+		min_bandwidth + N * bandwidth_gran.
+
+"delay_linear":
+		Indicates if the delay scale is linear or
+		non-linear. This field is purely informational
+		only.
+
+If RDT monitoring is available there will be an "L3_MON" directory
+with the following files:
+
+"num_rmids":
+		The number of RMIDs available. This is the
+		upper bound for how many "CTRL_MON" + "MON"
+		groups can be created.
+
+"mon_features":
+		Lists the monitoring events if
+		monitoring is enabled for the resource.
+
+"max_threshold_occupancy":
+		Read/write file provides the largest value (in
+		bytes) at which a previously used LLC_occupancy
+		counter can be considered for re-use.
+
+Finally, in the top level of the "info" directory there is a file
+named "last_cmd_status". This is reset with every "command" issued
+via the file system (making new directories or writing to any of the
+control files). If the command was successful, it will read as "ok".
+If the command failed, it will provide more information that can be
+conveyed in the error returns from file operations. E.g.
+::
+
+	# echo L3:0=f7 > schemata
+	bash: echo: write error: Invalid argument
+	# cat info/last_cmd_status
+	mask f7 has non-consecutive 1-bits
+
+Resource alloc and monitor groups
+=================================
+
+Resource groups are represented as directories in the resctrl file
+system.  The default group is the root directory which, immediately
+after mounting, owns all the tasks and cpus in the system and can make
+full use of all resources.
+
+On a system with RDT control features additional directories can be
+created in the root directory that specify different amounts of each
+resource (see "schemata" below). The root and these additional top level
+directories are referred to as "CTRL_MON" groups below.
+
+On a system with RDT monitoring the root directory and other top level
+directories contain a directory named "mon_groups" in which additional
+directories can be created to monitor subsets of tasks in the CTRL_MON
+group that is their ancestor. These are called "MON" groups in the rest
+of this document.
+
+Removing a directory will move all tasks and cpus owned by the group it
+represents to the parent. Removing one of the created CTRL_MON groups
+will automatically remove all MON groups below it.
+
+All groups contain the following files:
+
+"tasks":
+	Reading this file shows the list of all tasks that belong to
+	this group. Writing a task id to the file will add a task to the
+	group. If the group is a CTRL_MON group the task is removed from
+	whichever previous CTRL_MON group owned the task and also from
+	any MON group that owned the task. If the group is a MON group,
+	then the task must already belong to the CTRL_MON parent of this
+	group. The task is removed from any previous MON group.
+
+
+"cpus":
+	Reading this file shows a bitmask of the logical CPUs owned by
+	this group. Writing a mask to this file will add and remove
+	CPUs to/from this group. As with the tasks file a hierarchy is
+	maintained where MON groups may only include CPUs owned by the
+	parent CTRL_MON group.
+	When the resouce group is in pseudo-locked mode this file will
+	only be readable, reflecting the CPUs associated with the
+	pseudo-locked region.
+
+
+"cpus_list":
+	Just like "cpus", only using ranges of CPUs instead of bitmasks.
+
+
+When control is enabled all CTRL_MON groups will also contain:
+
+"schemata":
+	A list of all the resources available to this group.
+	Each resource has its own line and format - see below for details.
+
+"size":
+	Mirrors the display of the "schemata" file to display the size in
+	bytes of each allocation instead of the bits representing the
+	allocation.
+
+"mode":
+	The "mode" of the resource group dictates the sharing of its
+	allocations. A "shareable" resource group allows sharing of its
+	allocations while an "exclusive" resource group does not. A
+	cache pseudo-locked region is created by first writing
+	"pseudo-locksetup" to the "mode" file before writing the cache
+	pseudo-locked region's schemata to the resource group's "schemata"
+	file. On successful pseudo-locked region creation the mode will
+	automatically change to "pseudo-locked".
+
+When monitoring is enabled all MON groups will also contain:
+
+"mon_data":
+	This contains a set of files organized by L3 domain and by
+	RDT event. E.g. on a system with two L3 domains there will
+	be subdirectories "mon_L3_00" and "mon_L3_01".	Each of these
+	directories have one file per event (e.g. "llc_occupancy",
+	"mbm_total_bytes", and "mbm_local_bytes"). In a MON group these
+	files provide a read out of the current value of the event for
+	all tasks in the group. In CTRL_MON groups these files provide
+	the sum for all tasks in the CTRL_MON group and all tasks in
+	MON groups. Please see example section for more details on usage.
+
+Resource allocation rules
+-------------------------
+
+When a task is running the following rules define which resources are
+available to it:
+
+1) If the task is a member of a non-default group, then the schemata
+   for that group is used.
+
+2) Else if the task belongs to the default group, but is running on a
+   CPU that is assigned to some specific group, then the schemata for the
+   CPU's group is used.
+
+3) Otherwise the schemata for the default group is used.
+
+Resource monitoring rules
+-------------------------
+1) If a task is a member of a MON group, or non-default CTRL_MON group
+   then RDT events for the task will be reported in that group.
+
+2) If a task is a member of the default CTRL_MON group, but is running
+   on a CPU that is assigned to some specific group, then the RDT events
+   for the task will be reported in that group.
+
+3) Otherwise RDT events for the task will be reported in the root level
+   "mon_data" group.
+
+
+Notes on cache occupancy monitoring and control
+===============================================
+When moving a task from one group to another you should remember that
+this only affects *new* cache allocations by the task. E.g. you may have
+a task in a monitor group showing 3 MB of cache occupancy. If you move
+to a new group and immediately check the occupancy of the old and new
+groups you will likely see that the old group is still showing 3 MB and
+the new group zero. When the task accesses locations still in cache from
+before the move, the h/w does not update any counters. On a busy system
+you will likely see the occupancy in the old group go down as cache lines
+are evicted and re-used while the occupancy in the new group rises as
+the task accesses memory and loads into the cache are counted based on
+membership in the new group.
+
+The same applies to cache allocation control. Moving a task to a group
+with a smaller cache partition will not evict any cache lines. The
+process may continue to use them from the old partition.
+
+Hardware uses CLOSid(Class of service ID) and an RMID(Resource monitoring ID)
+to identify a control group and a monitoring group respectively. Each of
+the resource groups are mapped to these IDs based on the kind of group. The
+number of CLOSid and RMID are limited by the hardware and hence the creation of
+a "CTRL_MON" directory may fail if we run out of either CLOSID or RMID
+and creation of "MON" group may fail if we run out of RMIDs.
+
+max_threshold_occupancy - generic concepts
+------------------------------------------
+
+Note that an RMID once freed may not be immediately available for use as
+the RMID is still tagged the cache lines of the previous user of RMID.
+Hence such RMIDs are placed on limbo list and checked back if the cache
+occupancy has gone down. If there is a time when system has a lot of
+limbo RMIDs but which are not ready to be used, user may see an -EBUSY
+during mkdir.
+
+max_threshold_occupancy is a user configurable value to determine the
+occupancy at which an RMID can be freed.
+
+Schemata files - general concepts
+---------------------------------
+Each line in the file describes one resource. The line starts with
+the name of the resource, followed by specific values to be applied
+in each of the instances of that resource on the system.
+
+Cache IDs
+---------
+On current generation systems there is one L3 cache per socket and L2
+caches are generally just shared by the hyperthreads on a core, but this
+isn't an architectural requirement. We could have multiple separate L3
+caches on a socket, multiple cores could share an L2 cache. So instead
+of using "socket" or "core" to define the set of logical cpus sharing
+a resource we use a "Cache ID". At a given cache level this will be a
+unique number across the whole system (but it isn't guaranteed to be a
+contiguous sequence, there may be gaps).  To find the ID for each logical
+CPU look in /sys/devices/system/cpu/cpu*/cache/index*/id
+
+Cache Bit Masks (CBM)
+---------------------
+For cache resources we describe the portion of the cache that is available
+for allocation using a bitmask. The maximum value of the mask is defined
+by each cpu model (and may be different for different cache levels). It
+is found using CPUID, but is also provided in the "info" directory of
+the resctrl file system in "info/{resource}/cbm_mask". X86 hardware
+requires that these masks have all the '1' bits in a contiguous block. So
+0x3, 0x6 and 0xC are legal 4-bit masks with two bits set, but 0x5, 0x9
+and 0xA are not.  On a system with a 20-bit mask each bit represents 5%
+of the capacity of the cache. You could partition the cache into four
+equal parts with masks: 0x1f, 0x3e0, 0x7c00, 0xf8000.
+
+Memory bandwidth Allocation and monitoring
+==========================================
+
+For Memory bandwidth resource, by default the user controls the resource
+by indicating the percentage of total memory bandwidth.
+
+The minimum bandwidth percentage value for each cpu model is predefined
+and can be looked up through "info/MB/min_bandwidth". The bandwidth
+granularity that is allocated is also dependent on the cpu model and can
+be looked up at "info/MB/bandwidth_gran". The available bandwidth
+control steps are: min_bw + N * bw_gran. Intermediate values are rounded
+to the next control step available on the hardware.
+
+The bandwidth throttling is a core specific mechanism on some of Intel
+SKUs. Using a high bandwidth and a low bandwidth setting on two threads
+sharing a core will result in both threads being throttled to use the
+low bandwidth. The fact that Memory bandwidth allocation(MBA) is a core
+specific mechanism where as memory bandwidth monitoring(MBM) is done at
+the package level may lead to confusion when users try to apply control
+via the MBA and then monitor the bandwidth to see if the controls are
+effective. Below are such scenarios:
+
+1. User may *not* see increase in actual bandwidth when percentage
+   values are increased:
+
+This can occur when aggregate L2 external bandwidth is more than L3
+external bandwidth. Consider an SKL SKU with 24 cores on a package and
+where L2 external  is 10GBps (hence aggregate L2 external bandwidth is
+240GBps) and L3 external bandwidth is 100GBps. Now a workload with '20
+threads, having 50% bandwidth, each consuming 5GBps' consumes the max L3
+bandwidth of 100GBps although the percentage value specified is only 50%
+<< 100%. Hence increasing the bandwidth percentage will not yeild any
+more bandwidth. This is because although the L2 external bandwidth still
+has capacity, the L3 external bandwidth is fully used. Also note that
+this would be dependent on number of cores the benchmark is run on.
+
+2. Same bandwidth percentage may mean different actual bandwidth
+   depending on # of threads:
+
+For the same SKU in #1, a 'single thread, with 10% bandwidth' and '4
+thread, with 10% bandwidth' can consume upto 10GBps and 40GBps although
+they have same percentage bandwidth of 10%. This is simply because as
+threads start using more cores in an rdtgroup, the actual bandwidth may
+increase or vary although user specified bandwidth percentage is same.
+
+In order to mitigate this and make the interface more user friendly,
+resctrl added support for specifying the bandwidth in MBps as well.  The
+kernel underneath would use a software feedback mechanism or a "Software
+Controller(mba_sc)" which reads the actual bandwidth using MBM counters
+and adjust the memowy bandwidth percentages to ensure::
+
+	"actual bandwidth < user specified bandwidth".
+
+By default, the schemata would take the bandwidth percentage values
+where as user can switch to the "MBA software controller" mode using
+a mount option 'mba_MBps'. The schemata format is specified in the below
+sections.
+
+L3 schemata file details (code and data prioritization disabled)
+----------------------------------------------------------------
+With CDP disabled the L3 schemata format is::
+
+	L3:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+L3 schemata file details (CDP enabled via mount option to resctrl)
+------------------------------------------------------------------
+When CDP is enabled L3 control is split into two separate resources
+so you can specify independent masks for code and data like this::
+
+	L3data:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+	L3code:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+L2 schemata file details
+------------------------
+L2 cache does not support code and data prioritization, so the
+schemata format is always::
+
+	L2:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+Memory bandwidth Allocation (default mode)
+------------------------------------------
+
+Memory b/w domain is L3 cache.
+::
+
+	MB:<cache_id0>=bandwidth0;<cache_id1>=bandwidth1;...
+
+Memory bandwidth Allocation specified in MBps
+---------------------------------------------
+
+Memory bandwidth domain is L3 cache.
+::
+
+	MB:<cache_id0>=bw_MBps0;<cache_id1>=bw_MBps1;...
+
+Reading/writing the schemata file
+---------------------------------
+Reading the schemata file will show the state of all resources
+on all domains. When writing you only need to specify those values
+which you wish to change.  E.g.
+::
+
+  # cat schemata
+  L3DATA:0=fffff;1=fffff;2=fffff;3=fffff
+  L3CODE:0=fffff;1=fffff;2=fffff;3=fffff
+  # echo "L3DATA:2=3c0;" > schemata
+  # cat schemata
+  L3DATA:0=fffff;1=fffff;2=3c0;3=fffff
+  L3CODE:0=fffff;1=fffff;2=fffff;3=fffff
+
+Cache Pseudo-Locking
+====================
+CAT enables a user to specify the amount of cache space that an
+application can fill. Cache pseudo-locking builds on the fact that a
+CPU can still read and write data pre-allocated outside its current
+allocated area on a cache hit. With cache pseudo-locking, data can be
+preloaded into a reserved portion of cache that no application can
+fill, and from that point on will only serve cache hits. The cache
+pseudo-locked memory is made accessible to user space where an
+application can map it into its virtual address space and thus have
+a region of memory with reduced average read latency.
+
+The creation of a cache pseudo-locked region is triggered by a request
+from the user to do so that is accompanied by a schemata of the region
+to be pseudo-locked. The cache pseudo-locked region is created as follows:
+
+- Create a CAT allocation CLOSNEW with a CBM matching the schemata
+  from the user of the cache region that will contain the pseudo-locked
+  memory. This region must not overlap with any current CAT allocation/CLOS
+  on the system and no future overlap with this cache region is allowed
+  while the pseudo-locked region exists.
+- Create a contiguous region of memory of the same size as the cache
+  region.
+- Flush the cache, disable hardware prefetchers, disable preemption.
+- Make CLOSNEW the active CLOS and touch the allocated memory to load
+  it into the cache.
+- Set the previous CLOS as active.
+- At this point the closid CLOSNEW can be released - the cache
+  pseudo-locked region is protected as long as its CBM does not appear in
+  any CAT allocation. Even though the cache pseudo-locked region will from
+  this point on not appear in any CBM of any CLOS an application running with
+  any CLOS will be able to access the memory in the pseudo-locked region since
+  the region continues to serve cache hits.
+- The contiguous region of memory loaded into the cache is exposed to
+  user-space as a character device.
+
+Cache pseudo-locking increases the probability that data will remain
+in the cache via carefully configuring the CAT feature and controlling
+application behavior. There is no guarantee that data is placed in
+cache. Instructions like INVD, WBINVD, CLFLUSH, etc. can still evict
+“locked” data from cache. Power management C-states may shrink or
+power off cache. Deeper C-states will automatically be restricted on
+pseudo-locked region creation.
+
+It is required that an application using a pseudo-locked region runs
+with affinity to the cores (or a subset of the cores) associated
+with the cache on which the pseudo-locked region resides. A sanity check
+within the code will not allow an application to map pseudo-locked memory
+unless it runs with affinity to cores associated with the cache on which the
+pseudo-locked region resides. The sanity check is only done during the
+initial mmap() handling, there is no enforcement afterwards and the
+application self needs to ensure it remains affine to the correct cores.
+
+Pseudo-locking is accomplished in two stages:
+
+1) During the first stage the system administrator allocates a portion
+   of cache that should be dedicated to pseudo-locking. At this time an
+   equivalent portion of memory is allocated, loaded into allocated
+   cache portion, and exposed as a character device.
+2) During the second stage a user-space application maps (mmap()) the
+   pseudo-locked memory into its address space.
+
+Cache Pseudo-Locking Interface
+------------------------------
+A pseudo-locked region is created using the resctrl interface as follows:
+
+1) Create a new resource group by creating a new directory in /sys/fs/resctrl.
+2) Change the new resource group's mode to "pseudo-locksetup" by writing
+   "pseudo-locksetup" to the "mode" file.
+3) Write the schemata of the pseudo-locked region to the "schemata" file. All
+   bits within the schemata should be "unused" according to the "bit_usage"
+   file.
+
+On successful pseudo-locked region creation the "mode" file will contain
+"pseudo-locked" and a new character device with the same name as the resource
+group will exist in /dev/pseudo_lock. This character device can be mmap()'ed
+by user space in order to obtain access to the pseudo-locked memory region.
+
+An example of cache pseudo-locked region creation and usage can be found below.
+
+Cache Pseudo-Locking Debugging Interface
+----------------------------------------
+The pseudo-locking debugging interface is enabled by default (if
+CONFIG_DEBUG_FS is enabled) and can be found in /sys/kernel/debug/resctrl.
+
+There is no explicit way for the kernel to test if a provided memory
+location is present in the cache. The pseudo-locking debugging interface uses
+the tracing infrastructure to provide two ways to measure cache residency of
+the pseudo-locked region:
+
+1) Memory access latency using the pseudo_lock_mem_latency tracepoint. Data
+   from these measurements are best visualized using a hist trigger (see
+   example below). In this test the pseudo-locked region is traversed at
+   a stride of 32 bytes while hardware prefetchers and preemption
+   are disabled. This also provides a substitute visualization of cache
+   hits and misses.
+2) Cache hit and miss measurements using model specific precision counters if
+   available. Depending on the levels of cache on the system the pseudo_lock_l2
+   and pseudo_lock_l3 tracepoints are available.
+
+When a pseudo-locked region is created a new debugfs directory is created for
+it in debugfs as /sys/kernel/debug/resctrl/<newdir>. A single
+write-only file, pseudo_lock_measure, is present in this directory. The
+measurement of the pseudo-locked region depends on the number written to this
+debugfs file:
+
+1:
+     writing "1" to the pseudo_lock_measure file will trigger the latency
+     measurement captured in the pseudo_lock_mem_latency tracepoint. See
+     example below.
+2:
+     writing "2" to the pseudo_lock_measure file will trigger the L2 cache
+     residency (cache hits and misses) measurement captured in the
+     pseudo_lock_l2 tracepoint. See example below.
+3:
+     writing "3" to the pseudo_lock_measure file will trigger the L3 cache
+     residency (cache hits and misses) measurement captured in the
+     pseudo_lock_l3 tracepoint.
+
+All measurements are recorded with the tracing infrastructure. This requires
+the relevant tracepoints to be enabled before the measurement is triggered.
+
+Example of latency debugging interface
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+In this example a pseudo-locked region named "newlock" was created. Here is
+how we can measure the latency in cycles of reading from this region and
+visualize this data with a histogram that is available if CONFIG_HIST_TRIGGERS
+is set::
+
+  # :> /sys/kernel/debug/tracing/trace
+  # echo 'hist:keys=latency' > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/trigger
+  # echo 1 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/enable
+  # echo 1 > /sys/kernel/debug/resctrl/newlock/pseudo_lock_measure
+  # echo 0 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/enable
+  # cat /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/hist
+
+  # event histogram
+  #
+  # trigger info: hist:keys=latency:vals=hitcount:sort=hitcount:size=2048 [active]
+  #
+
+  { latency:        456 } hitcount:          1
+  { latency:         50 } hitcount:         83
+  { latency:         36 } hitcount:         96
+  { latency:         44 } hitcount:        174
+  { latency:         48 } hitcount:        195
+  { latency:         46 } hitcount:        262
+  { latency:         42 } hitcount:        693
+  { latency:         40 } hitcount:       3204
+  { latency:         38 } hitcount:       3484
+
+  Totals:
+      Hits: 8192
+      Entries: 9
+    Dropped: 0
+
+Example of cache hits/misses debugging
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+In this example a pseudo-locked region named "newlock" was created on the L2
+cache of a platform. Here is how we can obtain details of the cache hits
+and misses using the platform's precision counters.

+
+
+Examples for RDT allocation usage
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1) Example 1
+
+On a two socket machine (one L3 cache per socket) with just four bits
+for cache bit masks, minimum b/w of 10% with a memory bandwidth
+granularity of 10%.
+::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl
+  # cd /sys/fs/resctrl
+  # mkdir p0 p1
+  # echo "L3:0=3;1=c\nMB:0=50;1=50" > /sys/fs/resctrl/p0/schemata
+  # echo "L3:0=3;1=3\nMB:0=50;1=50" > /sys/fs/resctrl/p1/schemata
+
+The default resource group is unmodified, so we have access to all parts
+of all caches (its schemata file reads "L3:0=f;1=f").
+
+Tasks that are under the control of group "p0" may only allocate from the
+"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
+Tasks in group "p1" use the "lower" 50% of cache on both sockets.
+
+Similarly, tasks that are under the control of group "p0" may use a
+maximum memory b/w of 50% on socket0 and 50% on socket 1.
+Tasks in group "p1" may also use 50% memory b/w on both sockets.
+Note that unlike cache masks, memory b/w cannot specify whether these
+allocations can overlap or not. The allocations specifies the maximum
+b/w that the group may be able to use and the system admin can configure
+the b/w accordingly.
+
+If the MBA is specified in MB(megabytes) then user can enter the max b/w in MB
+rather than the percentage values.
+::
+
+  # echo "L3:0=3;1=c\nMB:0=1024;1=500" > /sys/fs/resctrl/p0/schemata
+  # echo "L3:0=3;1=3\nMB:0=1024;1=500" > /sys/fs/resctrl/p1/schemata
+
+In the above example the tasks in "p1" and "p0" on socket 0 would use a max b/w
+of 1024MB where as on socket 1 they would use 500MB.
+
+2) Example 2
+
+Again two sockets, but this time with a more realistic 20-bit mask.
+
+Two real time tasks pid=1234 running on processor 0 and pid=5678 running on
+processor 1 on socket 0 on a 2-socket and dual core machine. To avoid noisy
+neighbors, each of the two real-time tasks exclusively occupies one quarter
+of L3 cache on socket 0.
+::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl
+  # cd /sys/fs/resctrl
+
+First we reset the schemata for the default group so that the "upper"
+50% of the L3 cache on socket 0 and 50% of memory b/w cannot be used by
+ordinary tasks::
+
+  # echo "L3:0=3ff;1=fffff\nMB:0=50;1=100" > schemata
+
+Next we make a resource group for our first real time task and give
+it access to the "top" 25% of the cache on socket 0.
+::
+
+  # mkdir p0
+  # echo "L3:0=f8000;1=fffff" > p0/schemata
+
+Finally we move our first real time task into this resource group. We
+also use taskset(1) to ensure the task always runs on a dedicated CPU
+on socket 0. Most uses of resource groups will also constrain which
+processors tasks run on.
+::
+
+  # echo 1234 > p0/tasks
+  # taskset -cp 1 1234
+
+Ditto for the second real time task (with the remaining 25% of cache)::
+
+  # mkdir p1
+  # echo "L3:0=7c00;1=fffff" > p1/schemata
+  # echo 5678 > p1/tasks
+  # taskset -cp 2 5678
+
+For the same 2 socket system with memory b/w resource and CAT L3 the
+schemata would look like(Assume min_bandwidth 10 and bandwidth_gran is
+10):
+
+For our first real time task this would request 20% memory b/w on socket 0.
+::
+
+  # echo -e "L3:0=f8000;1=fffff\nMB:0=20;1=100" > p0/schemata
+
+For our second real time task this would request an other 20% memory b/w
+on socket 0.
+::
+
+  # echo -e "L3:0=f8000;1=fffff\nMB:0=20;1=100" > p0/schemata
+
+3) Example 3
+
+A single socket system which has real-time tasks running on core 4-7 and
+non real-time workload assigned to core 0-3. The real-time tasks share text
+and data, so a per task association is not required and due to interaction
+with the kernel it's desired that the kernel on these cores shares L3 with
+the tasks.
+::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl
+  # cd /sys/fs/resctrl
+
+First we reset the schemata for the default group so that the "upper"
+50% of the L3 cache on socket 0, and 50% of memory bandwidth on socket 0
+cannot be used by ordinary tasks::
+
+  # echo "L3:0=3ff\nMB:0=50" > schemata
+
+Next we make a resource group for our real time cores and give it access
+to the "top" 50% of the cache on socket 0 and 50% of memory bandwidth on
+socket 0.
+::
+
+  # mkdir p0
+  # echo "L3:0=ffc00\nMB:0=50" > p0/schemata
+
+Finally we move core 4-7 over to the new group and make sure that the
+kernel and the tasks running there get 50% of the cache. They should
+also get 50% of memory bandwidth assuming that the cores 4-7 are SMT
+siblings and only the real time threads are scheduled on the cores 4-7.
+::
+
+  # echo F0 > p0/cpus
+
+4) Example 4
+
+The resource groups in previous examples were all in the default "shareable"
+mode allowing sharing of their cache allocations. If one resource group
+configures a cache allocation then nothing prevents another resource group
+to overlap with that allocation.
+
+In this example a new exclusive resource group will be created on a L2 CAT
+system with two L2 cache instances that can be configured with an 8-bit
+capacity bitmask. The new exclusive resource group will be configured to use
+25% of each cache instance.
+::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl/
+  # cd /sys/fs/resctrl
+
+First, we observe that the default group is configured to allocate to all L2
+cache::
+
+  # cat schemata
+  L2:0=ff;1=ff
+
+We could attempt to create the new resource group at this point, but it will
+fail because of the overlap with the schemata of the default group::
+
+  # mkdir p0
+  # echo 'L2:0=0x3;1=0x3' > p0/schemata
+  # cat p0/mode
+  shareable
+  # echo exclusive > p0/mode
+  -sh: echo: write error: Invalid argument
+  # cat info/last_cmd_status
+  schemata overlaps
+
+To ensure that there is no overlap with another resource group the default
+resource group's schemata has to change, making it possible for the new
+resource group to become exclusive.
+::
+
+  # echo 'L2:0=0xfc;1=0xfc' > schemata
+  # echo exclusive > p0/mode
+  # grep . p0/*
+  p0/cpus:0
+  p0/mode:exclusive
+  p0/schemata:L2:0=03;1=03
+  p0/size:L2:0=262144;1=262144
+
+A new resource group will on creation not overlap with an exclusive resource
+group::
+
+  # mkdir p1
+  # grep . p1/*
+  p1/cpus:0
+  p1/mode:shareable
+  p1/schemata:L2:0=fc;1=fc
+  p1/size:L2:0=786432;1=786432
+
+The bit_usage will reflect how the cache is used::
+
+  # cat info/L2/bit_usage
+  0=SSSSSSEE;1=SSSSSSEE
+
+A resource group cannot be forced to overlap with an exclusive resource group::
+
+  # echo 'L2:0=0x1;1=0x1' > p1/schemata
+  -sh: echo: write error: Invalid argument
+  # cat info/last_cmd_status
+  overlaps with exclusive group
+
+Example of Cache Pseudo-Locking
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Lock portion of L2 cache from cache id 1 using CBM 0x3. Pseudo-locked
+region is exposed at /dev/pseudo_lock/newlock that can be provided to
+application for argument to mmap().
+::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl/
+  # cd /sys/fs/resctrl
+
+Ensure that there are bits available that can be pseudo-locked, since only
+unused bits can be pseudo-locked the bits to be pseudo-locked needs to be
+removed from the default resource group's schemata::
+
+  # cat info/L2/bit_usage
+  0=SSSSSSSS;1=SSSSSSSS
+  # echo 'L2:1=0xfc' > schemata
+  # cat info/L2/bit_usage
+  0=SSSSSSSS;1=SSSSSS00
+
+Create a new resource group that will be associated with the pseudo-locked
+region, indicate that it will be used for a pseudo-locked region, and
+configure the requested pseudo-locked region capacity bitmask::
+
+  # mkdir newlock
+  # echo pseudo-locksetup > newlock/mode
+  # echo 'L2:1=0x3' > newlock/schemata
+
+On success the resource group's mode will change to pseudo-locked, the
+bit_usage will reflect the pseudo-locked region, and the character device
+exposing the pseudo-locked region will exist::
+
+  # cat newlock/mode
+  pseudo-locked
+  # cat info/L2/bit_usage
+  0=SSSSSSSS;1=SSSSSSPP
+  # ls -l /dev/pseudo_lock/newlock

+  }
+
+Locking between applications
+----------------------------
+
+Certain operations on the resctrl filesystem, composed of read/writes
+to/from multiple files, must be atomic.
+
+As an example, the allocation of an exclusive reservation of L3 cache
+involves:
+
+  1. Read the cbmmasks from each directory or the per-resource "bit_usage"
+  2. Find a contiguous set of bits in the global CBM bitmask that is clear
+     in any of the directory cbmmasks
+  3. Create a new directory
+  4. Set the bits found in step 2 to the new directory "schemata" file
+
+If two applications attempt to allocate space concurrently then they can
+end up allocating the same bits so the reservations are shared instead of
+exclusive.
+
+To coordinate atomic operations on the resctrlfs and to avoid the problem
+above, the following locking procedure is recommended:
+
+Locking is based on flock, which is available in libc and also as a shell
+script command
+
+Write lock:
+
+ A) Take flock(LOCK_EX) on /sys/fs/resctrl
+ B) Read/write the directory structure.
+ C) funlock
+
+Read lock:
+
+ A) Take flock(LOCK_SH) on /sys/fs/resctrl
+ B) If success read the directory structure.
+ C) funlock
+
+Example with bash::
+
+  # Atomically read directory structure
+  $ flock -s /sys/fs/resctrl/ find /sys/fs/resctrl
+
+  # Read directory contents and create new subdirectory
+
+  $ cat create-dir.sh
+  find /sys/fs/resctrl/ > output.txt
+  mask = function-of(output.txt)
+  mkdir /sys/fs/resctrl/newres/
+  echo mask > /sys/fs/resctrl/newres/schemata
+
+  $ flock /sys/fs/resctrl/ ./create-dir.sh
+
+Example with C::
+
+  /*
+  * Example code do take advisory locks
+  * before accessing resctrl filesystem
+  */
+  #include <sys/file.h>
+  #include <stdlib.h>
+
+  void resctrl_take_shared_lock(int fd)
+  {
+    int ret;
+
+    /* take shared lock on resctrl filesystem */
+    ret = flock(fd, LOCK_SH);
+    if (ret) {
+      perror("flock");
+      exit(-1);
+    }
+  }
+
+  void resctrl_take_exclusive_lock(int fd)
+  {
+    int ret;
+
+    /* release lock on resctrl filesystem */
+    ret = flock(fd, LOCK_EX);
+    if (ret) {
+      perror("flock");
+      exit(-1);
+    }
+  }
+
+  void resctrl_release_lock(int fd)
+  {
+    int ret;
+
+    /* take shared lock on resctrl filesystem */
+    ret = flock(fd, LOCK_UN);
+    if (ret) {
+      perror("flock");
+      exit(-1);
+    }
+  }
+
+  void main(void)
+  {
+    int fd, ret;
+
+    fd = open("/sys/fs/resctrl", O_DIRECTORY);
+    if (fd == -1) {
+      perror("open");
+      exit(-1);
+    }
+    resctrl_take_shared_lock(fd);
+    /* code to read directory contents */
+    resctrl_release_lock(fd);
+
+    resctrl_take_exclusive_lock(fd);
+    /* code to read and write directory contents */
+    resctrl_release_lock(fd);
+  }
+
+Examples for RDT Monitoring along with allocation usage
+=======================================================
+Reading monitored data
+----------------------
+Reading an event file (for ex: mon_data/mon_L3_00/llc_occupancy) would
+show the current snapshot of LLC occupancy of the corresponding MON
+group or CTRL_MON group.
+
+
+Example 1 (Monitor CTRL_MON group and subset of tasks in CTRL_MON group)
+------------------------------------------------------------------------
+On a two socket machine (one L3 cache per socket) with just four bits
+for cache bit masks::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl
+  # cd /sys/fs/resctrl
+  # mkdir p0 p1
+  # echo "L3:0=3;1=c" > /sys/fs/resctrl/p0/schemata
+  # echo "L3:0=3;1=3" > /sys/fs/resctrl/p1/schemata
+  # echo 5678 > p1/tasks
+  # echo 5679 > p1/tasks
+
+The default resource group is unmodified, so we have access to all parts
+of all caches (its schemata file reads "L3:0=f;1=f").
+
+Tasks that are under the control of group "p0" may only allocate from the
+"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
+Tasks in group "p1" use the "lower" 50% of cache on both sockets.
+
+Create monitor groups and assign a subset of tasks to each monitor group.
+::
+
+  # cd /sys/fs/resctrl/p1/mon_groups
+  # mkdir m11 m12
+  # echo 5678 > m11/tasks
+  # echo 5679 > m12/tasks
+
+fetch data (data shown in bytes)
+::
+
+  # cat m11/mon_data/mon_L3_00/llc_occupancy
+  16234000
+  # cat m11/mon_data/mon_L3_01/llc_occupancy
+  14789000
+  # cat m12/mon_data/mon_L3_00/llc_occupancy
+  16789000
+
+The parent ctrl_mon group shows the aggregated data.
+::
+
+  # cat /sys/fs/resctrl/p1/mon_data/mon_l3_00/llc_occupancy
+  31234000
+
+Example 2 (Monitor a task from its creation)
+--------------------------------------------
+On a two socket machine (one L3 cache per socket)::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl
+  # cd /sys/fs/resctrl
+  # mkdir p0 p1
+
+An RMID is allocated to the group once its created and hence the <cmd>
+below is monitored from its creation.
+::
+
+  # echo $$ > /sys/fs/resctrl/p1/tasks
+  # <cmd>
+
+Fetch the data::
+
+  # cat /sys/fs/resctrl/p1/mon_data/mon_l3_00/llc_occupancy
+  31789000
+
+Example 3 (Monitor without CAT support or before creating CAT groups)
+---------------------------------------------------------------------
+
+Assume a system like HSW has only CQM and no CAT support. In this case
+the resctrl will still mount but cannot create CTRL_MON directories.
+But user can create different MON groups within the root group thereby
+able to monitor all tasks including kernel threads.
+
+This can also be used to profile jobs cache size footprint before being
+able to allocate them to different allocation groups.
+::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl
+  # cd /sys/fs/resctrl
+  # mkdir mon_groups/m01
+  # mkdir mon_groups/m02
+
+  # echo 3478 > /sys/fs/resctrl/mon_groups/m01/tasks
+  # echo 2467 > /sys/fs/resctrl/mon_groups/m02/tasks
+
+Monitor the groups separately and also get per domain data. From the
+below its apparent that the tasks are mostly doing work on
+domain(socket) 0.
+::
+
+  # cat /sys/fs/resctrl/mon_groups/m01/mon_L3_00/llc_occupancy
+  31234000
+  # cat /sys/fs/resctrl/mon_groups/m01/mon_L3_01/llc_occupancy
+  34555
+  # cat /sys/fs/resctrl/mon_groups/m02/mon_L3_00/llc_occupancy
+  31234000
+  # cat /sys/fs/resctrl/mon_groups/m02/mon_L3_01/llc_occupancy
+  32789
+
+
+Example 4 (Monitor real time tasks)
+-----------------------------------
+
+A single socket system which has real time tasks running on cores 4-7
+and non real time tasks on other cpus. We want to monitor the cache
+occupancy of the real time threads on these cores.
+::
+
+  # mount -t resctrl resctrl /sys/fs/resctrl
+  # cd /sys/fs/resctrl
+  # mkdir p1
+
+Move the cpus 4-7 over to p1::
+
+  # echo f0 > p1/cpus
+
+View the llc occupancy snapshot::
+
+  # cat /sys/fs/resctrl/p1/mon_data/mon_L3_00/llc_occupancy
+  11234000

-User Interface for Resource Control feature
-
-Intel refers to this feature as Intel Resource Director Technology(Intel(R) RDT).
-AMD refers to this feature as AMD Platform Quality of Service(AMD QoS).
-
-Copyright (C) 2016 Intel Corporation
-
-Fenghua Yu <fenghua.yu@intel.com>
-Tony Luck <tony.luck@intel.com>
-Vikas Shivappa <vikas.shivappa@intel.com>
-
-This feature is enabled by the CONFIG_X86_CPU_RESCTRL and the x86 /proc/cpuinfo
-flag bits:
-RDT (Resource Director Technology) Allocation - "rdt_a"
-CAT (Cache Allocation Technology) - "cat_l3", "cat_l2"
-CDP (Code and Data Prioritization ) - "cdp_l3", "cdp_l2"
-CQM (Cache QoS Monitoring) - "cqm_llc", "cqm_occup_llc"
-MBM (Memory Bandwidth Monitoring) - "cqm_mbm_total", "cqm_mbm_local"
-MBA (Memory Bandwidth Allocation) - "mba"
-
-To use the feature mount the file system:
-
- # mount -t resctrl resctrl [-o cdp[,cdpl2][,mba_MBps]] /sys/fs/resctrl
-
-mount options are:
-
-"cdp": Enable code/data prioritization in L3 cache allocations.
-"cdpl2": Enable code/data prioritization in L2 cache allocations.
-"mba_MBps": Enable the MBA Software Controller(mba_sc) to specify MBA
- bandwidth in MBps
-
-L2 and L3 CDP are controlled seperately.
-
-RDT features are orthogonal. A particular system may support only
-monitoring, only control, or both monitoring and control.  Cache
-pseudo-locking is a unique way of using cache control to "pin" or
-"lock" data in the cache. Details can be found in
-"Cache Pseudo-Locking".
-
-
-The mount succeeds if either of allocation or monitoring is present, but
-only those files and directories supported by the system will be created.
-For more details on the behavior of the interface during monitoring
-and allocation, see the "Resource alloc and monitor groups" section.
-
-Info directory
---------------
-
-The 'info' directory contains information about the enabled
-resources. Each resource has its own subdirectory. The subdirectory
-names reflect the resource names.
-
-Each subdirectory contains the following files with respect to
-allocation:
-
-Cache resource(L3/L2)  subdirectory contains the following files
-related to allocation:
-
-"num_closids":  	The number of CLOSIDs which are valid for this
-			resource. The kernel uses the smallest number of
-			CLOSIDs of all enabled resources as limit.
-
-"cbm_mask":     	The bitmask which is valid for this resource.
-			This mask is equivalent to 100%.
-
-"min_cbm_bits": 	The minimum number of consecutive bits which
-			must be set when writing a mask.
-
-"shareable_bits":	Bitmask of shareable resource with other executing
-			entities (e.g. I/O). User can use this when
-			setting up exclusive cache partitions. Note that
-			some platforms support devices that have their
-			own settings for cache use which can over-ride
-			these bits.
-"bit_usage":		Annotated capacity bitmasks showing how all
-			instances of the resource are used. The legend is:
-			"0" - Corresponding region is unused. When the system's
-			      resources have been allocated and a "0" is found
-			      in "bit_usage" it is a sign that resources are
-			      wasted.
-			"H" - Corresponding region is used by hardware only
-			      but available for software use. If a resource
-			      has bits set in "shareable_bits" but not all
-			      of these bits appear in the resource groups'
-			      schematas then the bits appearing in
-			      "shareable_bits" but no resource group will
-			      be marked as "H".
-			"X" - Corresponding region is available for sharing and
-			      used by hardware and software. These are the
-			      bits that appear in "shareable_bits" as
-			      well as a resource group's allocation.
-			"S" - Corresponding region is used by software
-			      and available for sharing.
-			"E" - Corresponding region is used exclusively by
-			      one resource group. No sharing allowed.
-			"P" - Corresponding region is pseudo-locked. No
-			      sharing allowed.
-
-Memory bandwitdh(MB) subdirectory contains the following files
-with respect to allocation:
-
-"min_bandwidth":	The minimum memory bandwidth percentage which
-			user can request.
-
-"bandwidth_gran":	The granularity in which the memory bandwidth
-			percentage is allocated. The allocated
-			b/w percentage is rounded off to the next
-			control step available on the hardware. The
-			available bandwidth control steps are:
-			min_bandwidth + N * bandwidth_gran.
-
-"delay_linear": 	Indicates if the delay scale is linear or
-			non-linear. This field is purely informational
-			only.
-
-If RDT monitoring is available there will be an "L3_MON" directory
-with the following files:
-
-"num_rmids":		The number of RMIDs available. This is the
-			upper bound for how many "CTRL_MON" + "MON"
-			groups can be created.
-
-"mon_features":	Lists the monitoring events if
-			monitoring is enabled for the resource.
-
-"max_threshold_occupancy":
-			Read/write file provides the largest value (in
-			bytes) at which a previously used LLC_occupancy
-			counter can be considered for re-use.
-
-Finally, in the top level of the "info" directory there is a file
-named "last_cmd_status". This is reset with every "command" issued
-via the file system (making new directories or writing to any of the
-control files). If the command was successful, it will read as "ok".
-If the command failed, it will provide more information that can be
-conveyed in the error returns from file operations. E.g.
-
-	# echo L3:0=f7 > schemata
-	bash: echo: write error: Invalid argument
-	# cat info/last_cmd_status
-	mask f7 has non-consecutive 1-bits
-
-Resource alloc and monitor groups
----------------------------------
-
-Resource groups are represented as directories in the resctrl file
-system.  The default group is the root directory which, immediately
-after mounting, owns all the tasks and cpus in the system and can make
-full use of all resources.
-
-On a system with RDT control features additional directories can be
-created in the root directory that specify different amounts of each
-resource (see "schemata" below). The root and these additional top level
-directories are referred to as "CTRL_MON" groups below.
-
-On a system with RDT monitoring the root directory and other top level
-directories contain a directory named "mon_groups" in which additional
-directories can be created to monitor subsets of tasks in the CTRL_MON
-group that is their ancestor. These are called "MON" groups in the rest
-of this document.
-
-Removing a directory will move all tasks and cpus owned by the group it
-represents to the parent. Removing one of the created CTRL_MON groups
-will automatically remove all MON groups below it.
-
-All groups contain the following files:
-
-"tasks":
-	Reading this file shows the list of all tasks that belong to
-	this group. Writing a task id to the file will add a task to the
-	group. If the group is a CTRL_MON group the task is removed from
-	whichever previous CTRL_MON group owned the task and also from
-	any MON group that owned the task. If the group is a MON group,
-	then the task must already belong to the CTRL_MON parent of this
-	group. The task is removed from any previous MON group.
-
-
-"cpus":
-	Reading this file shows a bitmask of the logical CPUs owned by
-	this group. Writing a mask to this file will add and remove
-	CPUs to/from this group. As with the tasks file a hierarchy is
-	maintained where MON groups may only include CPUs owned by the
-	parent CTRL_MON group.
-	When the resouce group is in pseudo-locked mode this file will
-	only be readable, reflecting the CPUs associated with the
-	pseudo-locked region.
-
-
-"cpus_list":
-	Just like "cpus", only using ranges of CPUs instead of bitmasks.
-
-
-When control is enabled all CTRL_MON groups will also contain:
-
-"schemata":
-	A list of all the resources available to this group.
-	Each resource has its own line and format - see below for details.
-
-"size":
-	Mirrors the display of the "schemata" file to display the size in
-	bytes of each allocation instead of the bits representing the
-	allocation.
-
-"mode":
-	The "mode" of the resource group dictates the sharing of its
-	allocations. A "shareable" resource group allows sharing of its
-	allocations while an "exclusive" resource group does not. A
-	cache pseudo-locked region is created by first writing
-	"pseudo-locksetup" to the "mode" file before writing the cache
-	pseudo-locked region's schemata to the resource group's "schemata"
-	file. On successful pseudo-locked region creation the mode will
-	automatically change to "pseudo-locked".
-
-When monitoring is enabled all MON groups will also contain:
-
-"mon_data":
-	This contains a set of files organized by L3 domain and by
-	RDT event. E.g. on a system with two L3 domains there will
-	be subdirectories "mon_L3_00" and "mon_L3_01".	Each of these
-	directories have one file per event (e.g. "llc_occupancy",
-	"mbm_total_bytes", and "mbm_local_bytes"). In a MON group these
-	files provide a read out of the current value of the event for
-	all tasks in the group. In CTRL_MON groups these files provide
-	the sum for all tasks in the CTRL_MON group and all tasks in
-	MON groups. Please see example section for more details on usage.

-Resource allocation rules
--------------------------
-When a task is running the following rules define which resources are
-available to it:
-
-1) If the task is a member of a non-default group, then the schemata
-   for that group is used.
-
-2) Else if the task belongs to the default group, but is running on a
-   CPU that is assigned to some specific group, then the schemata for the
-   CPU's group is used.
-
-3) Otherwise the schemata for the default group is used.
-
-Resource monitoring rules
--------------------------
-1) If a task is a member of a MON group, or non-default CTRL_MON group
-   then RDT events for the task will be reported in that group.
-
-2) If a task is a member of the default CTRL_MON group, but is running
-   on a CPU that is assigned to some specific group, then the RDT events
-   for the task will be reported in that group.
-
-3) Otherwise RDT events for the task will be reported in the root level
-   "mon_data" group.
-
-
-Notes on cache occupancy monitoring and control
------------------------------------------------
-When moving a task from one group to another you should remember that
-this only affects *new* cache allocations by the task. E.g. you may have
-a task in a monitor group showing 3 MB of cache occupancy. If you move
-to a new group and immediately check the occupancy of the old and new
-groups you will likely see that the old group is still showing 3 MB and
-the new group zero. When the task accesses locations still in cache from
-before the move, the h/w does not update any counters. On a busy system
-you will likely see the occupancy in the old group go down as cache lines
-are evicted and re-used while the occupancy in the new group rises as
-the task accesses memory and loads into the cache are counted based on
-membership in the new group.
-
-The same applies to cache allocation control. Moving a task to a group
-with a smaller cache partition will not evict any cache lines. The
-process may continue to use them from the old partition.
-
-Hardware uses CLOSid(Class of service ID) and an RMID(Resource monitoring ID)
-to identify a control group and a monitoring group respectively. Each of
-the resource groups are mapped to these IDs based on the kind of group. The
-number of CLOSid and RMID are limited by the hardware and hence the creation of
-a "CTRL_MON" directory may fail if we run out of either CLOSID or RMID
-and creation of "MON" group may fail if we run out of RMIDs.
-
-max_threshold_occupancy - generic concepts
-------------------------------------------
-
-Note that an RMID once freed may not be immediately available for use as
-the RMID is still tagged the cache lines of the previous user of RMID.
-Hence such RMIDs are placed on limbo list and checked back if the cache
-occupancy has gone down. If there is a time when system has a lot of
-limbo RMIDs but which are not ready to be used, user may see an -EBUSY
-during mkdir.
-
-max_threshold_occupancy is a user configurable value to determine the
-occupancy at which an RMID can be freed.
-
-Schemata files - general concepts
----------------------------------
-Each line in the file describes one resource. The line starts with
-the name of the resource, followed by specific values to be applied
-in each of the instances of that resource on the system.
-
-Cache IDs
----------
-On current generation systems there is one L3 cache per socket and L2
-caches are generally just shared by the hyperthreads on a core, but this
-isn't an architectural requirement. We could have multiple separate L3
-caches on a socket, multiple cores could share an L2 cache. So instead
-of using "socket" or "core" to define the set of logical cpus sharing
-a resource we use a "Cache ID". At a given cache level this will be a
-unique number across the whole system (but it isn't guaranteed to be a
-contiguous sequence, there may be gaps).  To find the ID for each logical
-CPU look in /sys/devices/system/cpu/cpu*/cache/index*/id
-
-Cache Bit Masks (CBM)
----------------------
-For cache resources we describe the portion of the cache that is available
-for allocation using a bitmask. The maximum value of the mask is defined
-by each cpu model (and may be different for different cache levels). It
-is found using CPUID, but is also provided in the "info" directory of
-the resctrl file system in "info/{resource}/cbm_mask". X86 hardware
-requires that these masks have all the '1' bits in a contiguous block. So
-0x3, 0x6 and 0xC are legal 4-bit masks with two bits set, but 0x5, 0x9
-and 0xA are not.  On a system with a 20-bit mask each bit represents 5%
-of the capacity of the cache. You could partition the cache into four
-equal parts with masks: 0x1f, 0x3e0, 0x7c00, 0xf8000.
-
-Memory bandwidth Allocation and monitoring
-------------------------------------------
-
-For Memory bandwidth resource, by default the user controls the resource
-by indicating the percentage of total memory bandwidth.
-
-The minimum bandwidth percentage value for each cpu model is predefined
-and can be looked up through "info/MB/min_bandwidth". The bandwidth
-granularity that is allocated is also dependent on the cpu model and can
-be looked up at "info/MB/bandwidth_gran". The available bandwidth
-control steps are: min_bw + N * bw_gran. Intermediate values are rounded
-to the next control step available on the hardware.
-
-The bandwidth throttling is a core specific mechanism on some of Intel
-SKUs. Using a high bandwidth and a low bandwidth setting on two threads
-sharing a core will result in both threads being throttled to use the
-low bandwidth. The fact that Memory bandwidth allocation(MBA) is a core
-specific mechanism where as memory bandwidth monitoring(MBM) is done at
-the package level may lead to confusion when users try to apply control
-via the MBA and then monitor the bandwidth to see if the controls are
-effective. Below are such scenarios:
-
-1. User may *not* see increase in actual bandwidth when percentage
-   values are increased:
-
-This can occur when aggregate L2 external bandwidth is more than L3
-external bandwidth. Consider an SKL SKU with 24 cores on a package and
-where L2 external  is 10GBps (hence aggregate L2 external bandwidth is
-240GBps) and L3 external bandwidth is 100GBps. Now a workload with '20
-threads, having 50% bandwidth, each consuming 5GBps' consumes the max L3
-bandwidth of 100GBps although the percentage value specified is only 50%
-<< 100%. Hence increasing the bandwidth percentage will not yeild any
-more bandwidth. This is because although the L2 external bandwidth still
-has capacity, the L3 external bandwidth is fully used. Also note that
-this would be dependent on number of cores the benchmark is run on.
-
-2. Same bandwidth percentage may mean different actual bandwidth
-   depending on # of threads:
-
-For the same SKU in #1, a 'single thread, with 10% bandwidth' and '4
-thread, with 10% bandwidth' can consume upto 10GBps and 40GBps although
-they have same percentage bandwidth of 10%. This is simply because as
-threads start using more cores in an rdtgroup, the actual bandwidth may
-increase or vary although user specified bandwidth percentage is same.
-
-In order to mitigate this and make the interface more user friendly,
-resctrl added support for specifying the bandwidth in MBps as well.  The
-kernel underneath would use a software feedback mechanism or a "Software
-Controller(mba_sc)" which reads the actual bandwidth using MBM counters
-and adjust the memowy bandwidth percentages to ensure
-
-	"actual bandwidth < user specified bandwidth".
-
-By default, the schemata would take the bandwidth percentage values
-where as user can switch to the "MBA software controller" mode using
-a mount option 'mba_MBps'. The schemata format is specified in the below
-sections.
-
-L3 schemata file details (code and data prioritization disabled)
-----------------------------------------------------------------
-With CDP disabled the L3 schemata format is:
-
-	L3:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
-
-L3 schemata file details (CDP enabled via mount option to resctrl)
-------------------------------------------------------------------
-When CDP is enabled L3 control is split into two separate resources
-so you can specify independent masks for code and data like this:
-
-	L3data:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
-	L3code:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
-
-L2 schemata file details
-------------------------
-L2 cache does not support code and data prioritization, so the
-schemata format is always:
-
-	L2:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
-
-Memory bandwidth Allocation (default mode)
-------------------------------------------
-
-Memory b/w domain is L3 cache.
-
-	MB:<cache_id0>=bandwidth0;<cache_id1>=bandwidth1;...
-
-Memory bandwidth Allocation specified in MBps
----------------------------------------------
-
-Memory bandwidth domain is L3 cache.
-
-	MB:<cache_id0>=bw_MBps0;<cache_id1>=bw_MBps1;...
-
-Reading/writing the schemata file
----------------------------------
-Reading the schemata file will show the state of all resources
-on all domains. When writing you only need to specify those values
-which you wish to change.  E.g.
-
-# cat schemata
-L3DATA:0=fffff;1=fffff;2=fffff;3=fffff
-L3CODE:0=fffff;1=fffff;2=fffff;3=fffff
-# echo "L3DATA:2=3c0;" > schemata
-# cat schemata
-L3DATA:0=fffff;1=fffff;2=3c0;3=fffff
-L3CODE:0=fffff;1=fffff;2=fffff;3=fffff
-
-Cache Pseudo-Locking
---------------------
-CAT enables a user to specify the amount of cache space that an
-application can fill. Cache pseudo-locking builds on the fact that a
-CPU can still read and write data pre-allocated outside its current
-allocated area on a cache hit. With cache pseudo-locking, data can be
-preloaded into a reserved portion of cache that no application can
-fill, and from that point on will only serve cache hits. The cache
-pseudo-locked memory is made accessible to user space where an
-application can map it into its virtual address space and thus have
-a region of memory with reduced average read latency.
-
-The creation of a cache pseudo-locked region is triggered by a request
-from the user to do so that is accompanied by a schemata of the region
-to be pseudo-locked. The cache pseudo-locked region is created as follows:
-- Create a CAT allocation CLOSNEW with a CBM matching the schemata
-  from the user of the cache region that will contain the pseudo-locked
-  memory. This region must not overlap with any current CAT allocation/CLOS
-  on the system and no future overlap with this cache region is allowed
-  while the pseudo-locked region exists.
-- Create a contiguous region of memory of the same size as the cache
-  region.
-- Flush the cache, disable hardware prefetchers, disable preemption.
-- Make CLOSNEW the active CLOS and touch the allocated memory to load
-  it into the cache.
-- Set the previous CLOS as active.
-- At this point the closid CLOSNEW can be released - the cache
-  pseudo-locked region is protected as long as its CBM does not appear in
-  any CAT allocation. Even though the cache pseudo-locked region will from
-  this point on not appear in any CBM of any CLOS an application running with
-  any CLOS will be able to access the memory in the pseudo-locked region since
-  the region continues to serve cache hits.
-- The contiguous region of memory loaded into the cache is exposed to
-  user-space as a character device.
-
-Cache pseudo-locking increases the probability that data will remain
-in the cache via carefully configuring the CAT feature and controlling
-application behavior. There is no guarantee that data is placed in
-cache. Instructions like INVD, WBINVD, CLFLUSH, etc. can still evict
-“locked” data from cache. Power management C-states may shrink or
-power off cache. Deeper C-states will automatically be restricted on
-pseudo-locked region creation.
-
-It is required that an application using a pseudo-locked region runs
-with affinity to the cores (or a subset of the cores) associated
-with the cache on which the pseudo-locked region resides. A sanity check
-within the code will not allow an application to map pseudo-locked memory
-unless it runs with affinity to cores associated with the cache on which the
-pseudo-locked region resides. The sanity check is only done during the
-initial mmap() handling, there is no enforcement afterwards and the
-application self needs to ensure it remains affine to the correct cores.
-
-Pseudo-locking is accomplished in two stages:
-1) During the first stage the system administrator allocates a portion
-   of cache that should be dedicated to pseudo-locking. At this time an
-   equivalent portion of memory is allocated, loaded into allocated
-   cache portion, and exposed as a character device.
-2) During the second stage a user-space application maps (mmap()) the
-   pseudo-locked memory into its address space.
-
-Cache Pseudo-Locking Interface
-------------------------------
-A pseudo-locked region is created using the resctrl interface as follows:
-
-1) Create a new resource group by creating a new directory in /sys/fs/resctrl.
-2) Change the new resource group's mode to "pseudo-locksetup" by writing
-   "pseudo-locksetup" to the "mode" file.
-3) Write the schemata of the pseudo-locked region to the "schemata" file. All
-   bits within the schemata should be "unused" according to the "bit_usage"
-   file.
-
-On successful pseudo-locked region creation the "mode" file will contain
-"pseudo-locked" and a new character device with the same name as the resource
-group will exist in /dev/pseudo_lock. This character device can be mmap()'ed
-by user space in order to obtain access to the pseudo-locked memory region.
-
-An example of cache pseudo-locked region creation and usage can be found below.
-
-Cache Pseudo-Locking Debugging Interface
----------------------------------------
-The pseudo-locking debugging interface is enabled by default (if
-CONFIG_DEBUG_FS is enabled) and can be found in /sys/kernel/debug/resctrl.
-
-There is no explicit way for the kernel to test if a provided memory
-location is present in the cache. The pseudo-locking debugging interface uses
-the tracing infrastructure to provide two ways to measure cache residency of
-the pseudo-locked region:
-1) Memory access latency using the pseudo_lock_mem_latency tracepoint. Data
-   from these measurements are best visualized using a hist trigger (see
-   example below). In this test the pseudo-locked region is traversed at
-   a stride of 32 bytes while hardware prefetchers and preemption
-   are disabled. This also provides a substitute visualization of cache
-   hits and misses.
-2) Cache hit and miss measurements using model specific precision counters if
-   available. Depending on the levels of cache on the system the pseudo_lock_l2
-   and pseudo_lock_l3 tracepoints are available.
-
-When a pseudo-locked region is created a new debugfs directory is created for
-it in debugfs as /sys/kernel/debug/resctrl/<newdir>. A single
-write-only file, pseudo_lock_measure, is present in this directory. The
-measurement of the pseudo-locked region depends on the number written to this
-debugfs file:
-1 -  writing "1" to the pseudo_lock_measure file will trigger the latency
-     measurement captured in the pseudo_lock_mem_latency tracepoint. See
-     example below.
-2 -  writing "2" to the pseudo_lock_measure file will trigger the L2 cache
-     residency (cache hits and misses) measurement captured in the
-     pseudo_lock_l2 tracepoint. See example below.
-3 -  writing "3" to the pseudo_lock_measure file will trigger the L3 cache
-     residency (cache hits and misses) measurement captured in the
-     pseudo_lock_l3 tracepoint.
-
-All measurements are recorded with the tracing infrastructure. This requires
-the relevant tracepoints to be enabled before the measurement is triggered.
-
-Example of latency debugging interface:
-In this example a pseudo-locked region named "newlock" was created. Here is
-how we can measure the latency in cycles of reading from this region and
-visualize this data with a histogram that is available if CONFIG_HIST_TRIGGERS
-is set:
-# :> /sys/kernel/debug/tracing/trace
-# echo 'hist:keys=latency' > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/trigger
-# echo 1 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/enable
-# echo 1 > /sys/kernel/debug/resctrl/newlock/pseudo_lock_measure
-# echo 0 > /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/enable
-# cat /sys/kernel/debug/tracing/events/resctrl/pseudo_lock_mem_latency/hist

-
-Example of cache hits/misses debugging:
-In this example a pseudo-locked region named "newlock" was created on the L2
-cache of a platform. Here is how we can obtain details of the cache hits
-and misses using the platform's precision counters.

-Examples for RDT allocation usage:
-
-Example 1
----------
-On a two socket machine (one L3 cache per socket) with just four bits
-for cache bit masks, minimum b/w of 10% with a memory bandwidth
-granularity of 10%
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir p0 p1
-# echo "L3:0=3;1=c\nMB:0=50;1=50" > /sys/fs/resctrl/p0/schemata
-# echo "L3:0=3;1=3\nMB:0=50;1=50" > /sys/fs/resctrl/p1/schemata
-
-The default resource group is unmodified, so we have access to all parts
-of all caches (its schemata file reads "L3:0=f;1=f").
-
-Tasks that are under the control of group "p0" may only allocate from the
-"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
-Tasks in group "p1" use the "lower" 50% of cache on both sockets.
-
-Similarly, tasks that are under the control of group "p0" may use a
-maximum memory b/w of 50% on socket0 and 50% on socket 1.
-Tasks in group "p1" may also use 50% memory b/w on both sockets.
-Note that unlike cache masks, memory b/w cannot specify whether these
-allocations can overlap or not. The allocations specifies the maximum
-b/w that the group may be able to use and the system admin can configure
-the b/w accordingly.
-
-If the MBA is specified in MB(megabytes) then user can enter the max b/w in MB
-rather than the percentage values.
-
-# echo "L3:0=3;1=c\nMB:0=1024;1=500" > /sys/fs/resctrl/p0/schemata
-# echo "L3:0=3;1=3\nMB:0=1024;1=500" > /sys/fs/resctrl/p1/schemata
-
-In the above example the tasks in "p1" and "p0" on socket 0 would use a max b/w
-of 1024MB where as on socket 1 they would use 500MB.
-
-Example 2
----------
-Again two sockets, but this time with a more realistic 20-bit mask.
-
-Two real time tasks pid=1234 running on processor 0 and pid=5678 running on
-processor 1 on socket 0 on a 2-socket and dual core machine. To avoid noisy
-neighbors, each of the two real-time tasks exclusively occupies one quarter
-of L3 cache on socket 0.
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-
-First we reset the schemata for the default group so that the "upper"
-50% of the L3 cache on socket 0 and 50% of memory b/w cannot be used by
-ordinary tasks:
-
-# echo "L3:0=3ff;1=fffff\nMB:0=50;1=100" > schemata
-
-Next we make a resource group for our first real time task and give
-it access to the "top" 25% of the cache on socket 0.
-
-# mkdir p0
-# echo "L3:0=f8000;1=fffff" > p0/schemata
-
-Finally we move our first real time task into this resource group. We
-also use taskset(1) to ensure the task always runs on a dedicated CPU
-on socket 0. Most uses of resource groups will also constrain which
-processors tasks run on.
-
-# echo 1234 > p0/tasks
-# taskset -cp 1 1234
-
-Ditto for the second real time task (with the remaining 25% of cache):
-
-# mkdir p1
-# echo "L3:0=7c00;1=fffff" > p1/schemata
-# echo 5678 > p1/tasks
-# taskset -cp 2 5678
-
-For the same 2 socket system with memory b/w resource and CAT L3 the
-schemata would look like(Assume min_bandwidth 10 and bandwidth_gran is
-10):
-
-For our first real time task this would request 20% memory b/w on socket
-0.
-
-# echo -e "L3:0=f8000;1=fffff\nMB:0=20;1=100" > p0/schemata
-
-For our second real time task this would request an other 20% memory b/w
-on socket 0.
-
-# echo -e "L3:0=f8000;1=fffff\nMB:0=20;1=100" > p0/schemata
-
-Example 3
----------
-
-A single socket system which has real-time tasks running on core 4-7 and
-non real-time workload assigned to core 0-3. The real-time tasks share text
-and data, so a per task association is not required and due to interaction
-with the kernel it's desired that the kernel on these cores shares L3 with
-the tasks.
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-
-First we reset the schemata for the default group so that the "upper"
-50% of the L3 cache on socket 0, and 50% of memory bandwidth on socket 0
-cannot be used by ordinary tasks:
-
-# echo "L3:0=3ff\nMB:0=50" > schemata
-
-Next we make a resource group for our real time cores and give it access
-to the "top" 50% of the cache on socket 0 and 50% of memory bandwidth on
-socket 0.
-
-# mkdir p0
-# echo "L3:0=ffc00\nMB:0=50" > p0/schemata
-
-Finally we move core 4-7 over to the new group and make sure that the
-kernel and the tasks running there get 50% of the cache. They should
-also get 50% of memory bandwidth assuming that the cores 4-7 are SMT
-siblings and only the real time threads are scheduled on the cores 4-7.
-
-# echo F0 > p0/cpus
-
-Example 4
----------
-
-The resource groups in previous examples were all in the default "shareable"
-mode allowing sharing of their cache allocations. If one resource group
-configures a cache allocation then nothing prevents another resource group
-to overlap with that allocation.
-
-In this example a new exclusive resource group will be created on a L2 CAT
-system with two L2 cache instances that can be configured with an 8-bit
-capacity bitmask. The new exclusive resource group will be configured to use
-25% of each cache instance.
-
-# mount -t resctrl resctrl /sys/fs/resctrl/
-# cd /sys/fs/resctrl
-
-First, we observe that the default group is configured to allocate to all L2
-cache:
-
-# cat schemata
-L2:0=ff;1=ff
-
-We could attempt to create the new resource group at this point, but it will
-fail because of the overlap with the schemata of the default group:
-# mkdir p0
-# echo 'L2:0=0x3;1=0x3' > p0/schemata
-# cat p0/mode
-shareable
-# echo exclusive > p0/mode
--sh: echo: write error: Invalid argument
-# cat info/last_cmd_status
-schemata overlaps
-
-To ensure that there is no overlap with another resource group the default
-resource group's schemata has to change, making it possible for the new
-resource group to become exclusive.
-# echo 'L2:0=0xfc;1=0xfc' > schemata
-# echo exclusive > p0/mode
-# grep . p0/*
-p0/cpus:0
-p0/mode:exclusive
-p0/schemata:L2:0=03;1=03
-p0/size:L2:0=262144;1=262144
-
-A new resource group will on creation not overlap with an exclusive resource
-group:
-# mkdir p1
-# grep . p1/*
-p1/cpus:0
-p1/mode:shareable
-p1/schemata:L2:0=fc;1=fc
-p1/size:L2:0=786432;1=786432
-
-The bit_usage will reflect how the cache is used:
-# cat info/L2/bit_usage
-0=SSSSSSEE;1=SSSSSSEE
-
-A resource group cannot be forced to overlap with an exclusive resource group:
-# echo 'L2:0=0x1;1=0x1' > p1/schemata
--sh: echo: write error: Invalid argument
-# cat info/last_cmd_status
-overlaps with exclusive group
-
-Example of Cache Pseudo-Locking
--------------------------------
-Lock portion of L2 cache from cache id 1 using CBM 0x3. Pseudo-locked
-region is exposed at /dev/pseudo_lock/newlock that can be provided to
-application for argument to mmap().
-
-# mount -t resctrl resctrl /sys/fs/resctrl/
-# cd /sys/fs/resctrl
-
-Ensure that there are bits available that can be pseudo-locked, since only
-unused bits can be pseudo-locked the bits to be pseudo-locked needs to be
-removed from the default resource group's schemata:
-# cat info/L2/bit_usage
-0=SSSSSSSS;1=SSSSSSSS
-# echo 'L2:1=0xfc' > schemata
-# cat info/L2/bit_usage
-0=SSSSSSSS;1=SSSSSS00
-
-Create a new resource group that will be associated with the pseudo-locked
-region, indicate that it will be used for a pseudo-locked region, and
-configure the requested pseudo-locked region capacity bitmask:
-
-# mkdir newlock
-# echo pseudo-locksetup > newlock/mode
-# echo 'L2:1=0x3' > newlock/schemata
-
-On success the resource group's mode will change to pseudo-locked, the
-bit_usage will reflect the pseudo-locked region, and the character device
-exposing the pseudo-locked region will exist:
-
-# cat newlock/mode
-pseudo-locked
-# cat info/L2/bit_usage
-0=SSSSSSSS;1=SSSSSSPP
-# ls -l /dev/pseudo_lock/newlock
-crw------- 1 root root 243, 0 Apr  3 05:01 /dev/pseudo_lock/newlock

-Locking between applications
-----------------------------
-
-Certain operations on the resctrl filesystem, composed of read/writes
-to/from multiple files, must be atomic.
-
-As an example, the allocation of an exclusive reservation of L3 cache
-involves:
-
-  1. Read the cbmmasks from each directory or the per-resource "bit_usage"
-  2. Find a contiguous set of bits in the global CBM bitmask that is clear
-     in any of the directory cbmmasks
-  3. Create a new directory
-  4. Set the bits found in step 2 to the new directory "schemata" file
-
-If two applications attempt to allocate space concurrently then they can
-end up allocating the same bits so the reservations are shared instead of
-exclusive.
-
-To coordinate atomic operations on the resctrlfs and to avoid the problem
-above, the following locking procedure is recommended:
-
-Locking is based on flock, which is available in libc and also as a shell
-script command
-
-Write lock:
-
- A) Take flock(LOCK_EX) on /sys/fs/resctrl
- B) Read/write the directory structure.
- C) funlock
-
-Read lock:
-
- A) Take flock(LOCK_SH) on /sys/fs/resctrl
- B) If success read the directory structure.
- C) funlock
-
-Example with bash:
-
-# Atomically read directory structure
-$ flock -s /sys/fs/resctrl/ find /sys/fs/resctrl
-
-# Read directory contents and create new subdirectory
-
-$ cat create-dir.sh
-find /sys/fs/resctrl/ > output.txt
-mask = function-of(output.txt)
-mkdir /sys/fs/resctrl/newres/
-echo mask > /sys/fs/resctrl/newres/schemata
-
-$ flock /sys/fs/resctrl/ ./create-dir.sh
-
-Example with C:
-
-/*
- * Example code do take advisory locks
- * before accessing resctrl filesystem
- */
-#include <sys/file.h>
-#include <stdlib.h>
-
-void resctrl_take_shared_lock(int fd)
-{
-	int ret;
-
-	/* take shared lock on resctrl filesystem */
-	ret = flock(fd, LOCK_SH);
-	if (ret) {
-		perror("flock");
-		exit(-1);
-	}
-}
-
-void resctrl_take_exclusive_lock(int fd)
-{
-	int ret;
-
-	/* release lock on resctrl filesystem */
-	ret = flock(fd, LOCK_EX);
-	if (ret) {
-		perror("flock");
-		exit(-1);
-	}

-
-void resctrl_release_lock(int fd)
-{
-	int ret;
-
-	/* take shared lock on resctrl filesystem */
-	ret = flock(fd, LOCK_UN);
-	if (ret) {
-		perror("flock");
-		exit(-1);
-	}
-}
-

-Examples for RDT Monitoring along with allocation usage:
-
-Reading monitored data
-----------------------
-Reading an event file (for ex: mon_data/mon_L3_00/llc_occupancy) would
-show the current snapshot of LLC occupancy of the corresponding MON
-group or CTRL_MON group.
-
-
-Example 1 (Monitor CTRL_MON group and subset of tasks in CTRL_MON group)
----------
-On a two socket machine (one L3 cache per socket) with just four bits
-for cache bit masks
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir p0 p1
-# echo "L3:0=3;1=c" > /sys/fs/resctrl/p0/schemata
-# echo "L3:0=3;1=3" > /sys/fs/resctrl/p1/schemata
-# echo 5678 > p1/tasks
-# echo 5679 > p1/tasks
-
-The default resource group is unmodified, so we have access to all parts
-of all caches (its schemata file reads "L3:0=f;1=f").
-
-Tasks that are under the control of group "p0" may only allocate from the
-"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
-Tasks in group "p1" use the "lower" 50% of cache on both sockets.
-
-Create monitor groups and assign a subset of tasks to each monitor group.
-
-# cd /sys/fs/resctrl/p1/mon_groups
-# mkdir m11 m12
-# echo 5678 > m11/tasks
-# echo 5679 > m12/tasks
-
-fetch data (data shown in bytes)
-
-# cat m11/mon_data/mon_L3_00/llc_occupancy
-16234000
-# cat m11/mon_data/mon_L3_01/llc_occupancy
-14789000
-# cat m12/mon_data/mon_L3_00/llc_occupancy
-16789000
-
-The parent ctrl_mon group shows the aggregated data.
-
-# cat /sys/fs/resctrl/p1/mon_data/mon_l3_00/llc_occupancy
-31234000
-
-Example 2 (Monitor a task from its creation)
----------
-On a two socket machine (one L3 cache per socket)
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir p0 p1
-
-An RMID is allocated to the group once its created and hence the <cmd>
-below is monitored from its creation.
-
-# echo $$ > /sys/fs/resctrl/p1/tasks
-# <cmd>
-
-Fetch the data
-
-# cat /sys/fs/resctrl/p1/mon_data/mon_l3_00/llc_occupancy
-31789000
-
-Example 3 (Monitor without CAT support or before creating CAT groups)
----------
-
-Assume a system like HSW has only CQM and no CAT support. In this case
-the resctrl will still mount but cannot create CTRL_MON directories.
-But user can create different MON groups within the root group thereby
-able to monitor all tasks including kernel threads.
-
-This can also be used to profile jobs cache size footprint before being
-able to allocate them to different allocation groups.
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir mon_groups/m01
-# mkdir mon_groups/m02
-
-# echo 3478 > /sys/fs/resctrl/mon_groups/m01/tasks
-# echo 2467 > /sys/fs/resctrl/mon_groups/m02/tasks
-
-Monitor the groups separately and also get per domain data. From the
-below its apparent that the tasks are mostly doing work on
-domain(socket) 0.
-
-# cat /sys/fs/resctrl/mon_groups/m01/mon_L3_00/llc_occupancy
-31234000
-# cat /sys/fs/resctrl/mon_groups/m01/mon_L3_01/llc_occupancy
-34555
-# cat /sys/fs/resctrl/mon_groups/m02/mon_L3_00/llc_occupancy
-31234000
-# cat /sys/fs/resctrl/mon_groups/m02/mon_L3_01/llc_occupancy
-32789
-
-
-Example 4 (Monitor real time tasks)
------------------------------------
-
-A single socket system which has real time tasks running on cores 4-7
-and non real time tasks on other cpus. We want to monitor the cache
-occupancy of the real time threads on these cores.
-
-# mount -t resctrl resctrl /sys/fs/resctrl
-# cd /sys/fs/resctrl
-# mkdir p1
-
-Move the cpus 4-7 over to p1
-# echo f0 > p1/cpus
-
-View the llc occupancy snapshot
-
-# cat /sys/fs/resctrl/p1/mon_data/mon_L3_00/llc_occupancy

+=======
+The TLB
+=======
+
+When the kernel unmaps or modified the attributes of a range of
+memory, it has two choices:
+
+ 1. Flush the entire TLB with a two-instruction sequence.  This is
+    a quick operation, but it causes collateral damage: TLB entries
+    from areas other than the one we are trying to flush will be
+    destroyed and must be refilled later, at some cost.
+ 2. Use the invlpg instruction to invalidate a single page at a
+    time.  This could potentially cost many more instructions, but
+    it is a much more precise operation, causing no collateral
+    damage to other TLB entries.
+
+Which method to do depends on a few things:
+
+ 1. The size of the flush being performed.  A flush of the entire
+    address space is obviously better performed by flushing the
+    entire TLB than doing 2^48/PAGE_SIZE individual flushes.
+ 2. The contents of the TLB.  If the TLB is empty, then there will
+    be no collateral damage caused by doing the global flush, and
+    all of the individual flush will have ended up being wasted
+    work.
+ 3. The size of the TLB.  The larger the TLB, the more collateral
+    damage we do with a full flush.  So, the larger the TLB, the
+    more attractive an individual flush looks.  Data and
+    instructions have separate TLBs, as do different page sizes.
+ 4. The microarchitecture.  The TLB has become a multi-level
+    cache on modern CPUs, and the global flushes have become more
+    expensive relative to single-page flushes.
+
+There is obviously no way the kernel can know all these things,
+especially the contents of the TLB during a given flush.  The
+sizes of the flush will vary greatly depending on the workload as
+well.  There is essentially no "right" point to choose.
+
+You may be doing too many individual invalidations if you see the
+invlpg instruction (or instructions _near_ it) show up high in
+profiles.  If you believe that individual invalidations being
+called too often, you can lower the tunable::
+
+	/sys/kernel/debug/x86/tlb_single_page_flush_ceiling
+
+This will cause us to do the global flush for more cases.
+Lowering it to 0 will disable the use of the individual flushes.
+Setting it to 1 is a very conservative setting and it should
+never need to be 0 under normal circumstances.
+
+Despite the fact that a single individual flush on x86 is
+guaranteed to flush a full 2MB [1]_, hugetlbfs always uses the full
+flushes.  THP is treated exactly the same as normal memory.
+
+You might see invlpg inside of flush_tlb_mm_range() show up in
+profiles, or you can use the trace_tlb_flush() tracepoints. to
+determine how long the flush operations are taking.
+
+Essentially, you are balancing the cycles you spend doing invlpg
+with the cycles that you spend refilling the TLB later.
+
+You can measure how expensive TLB refills are by using
+performance counters and 'perf stat', like this::
+
+  perf stat -e
+    cpu/event=0x8,umask=0x84,name=dtlb_load_misses_walk_duration/,
+    cpu/event=0x8,umask=0x82,name=dtlb_load_misses_walk_completed/,
+    cpu/event=0x49,umask=0x4,name=dtlb_store_misses_walk_duration/,

+    cpu/event=0x85,umask=0x2,name=itlb_misses_walk_completed/
+
+That works on an IvyBridge-era CPU (i5-3320M).  Different CPUs
+may have differently-named counters, but they should at least
+be there in some form.  You can use pmu-tools 'ocperf list'
+(https://github.com/andikleen/pmu-tools) to find the right
+counters for a given CPU.

+x86 Topology
+============
+
+This documents and clarifies the main aspects of x86 topology modelling and
+representation in the kernel. Update/change when doing changes to the
+respective code.
+
+The architecture-agnostic topology definitions are in
+Documentation/cputopology.txt. This file holds x86-specific
+differences/specialities which must not necessarily apply to the generic
+definitions. Thus, the way to read up on Linux topology on x86 is to start
+with the generic one and look at this one in parallel for the x86 specifics.
+
+Needless to say, code should use the generic functions - this file is *only*
+here to *document* the inner workings of x86 topology.
+
+Started by Thomas Gleixner <tglx@linutronix.de> and Borislav Petkov <bp@alien8.de>.
+
+The main aim of the topology facilities is to present adequate interfaces to
+code which needs to know/query/use the structure of the running system wrt
+threads, cores, packages, etc.
+
+The kernel does not care about the concept of physical sockets because a
+socket has no relevance to software. It's an electromechanical component. In
+the past a socket always contained a single package (see below), but with the
+advent of Multi Chip Modules (MCM) a socket can hold more than one package. So
+there might be still references to sockets in the code, but they are of
+historical nature and should be cleaned up.
+
+The topology of a system is described in the units of:
+
+    - packages
+    - cores
+    - threads
+
+Package
+=======
+Packages contain a number of cores plus shared resources, e.g. DRAM
+controller, shared caches etc.
+
+AMD nomenclature for package is 'Node'.
+
+Package-related topology information in the kernel:
+
+  - cpuinfo_x86.x86_max_cores:
+
+    The number of cores in a package. This information is retrieved via CPUID.
+
+  - cpuinfo_x86.phys_proc_id:
+
+    The physical ID of the package. This information is retrieved via CPUID
+    and deduced from the APIC IDs of the cores in the package.
+
+  - cpuinfo_x86.logical_proc_id:
+
+    The logical ID of the package. As we do not trust BIOSes to enumerate the
+    packages in a consistent way, we introduced the concept of logical package
+    ID so we can sanely calculate the number of maximum possible packages in
+    the system and have the packages enumerated linearly.
+
+  - topology_max_packages():
+
+    The maximum possible number of packages in the system. Helpful for per
+    package facilities to preallocate per package information.
+
+  - cpu_llc_id:
+
+    A per-CPU variable containing:
+
+      - On Intel, the first APIC ID of the list of CPUs sharing the Last Level
+        Cache
+
+      - On AMD, the Node ID or Core Complex ID containing the Last Level
+        Cache. In general, it is a number identifying an LLC uniquely on the
+        system.
+
+Cores
+=====
+A core consists of 1 or more threads. It does not matter whether the threads
+are SMT- or CMT-type threads.
+
+AMDs nomenclature for a CMT core is "Compute Unit". The kernel always uses
+"core".
+
+Core-related topology information in the kernel:
+
+  - smp_num_siblings:
+
+    The number of threads in a core. The number of threads in a package can be
+    calculated by::
+
+	threads_per_package = cpuinfo_x86.x86_max_cores * smp_num_siblings
+
+
+Threads
+=======
+A thread is a single scheduling unit. It's the equivalent to a logical Linux
+CPU.
+
+AMDs nomenclature for CMT threads is "Compute Unit Core". The kernel always
+uses "thread".
+
+Thread-related topology information in the kernel:
+
+  - topology_core_cpumask():
+
+    The cpumask contains all online threads in the package to which a thread
+    belongs.
+
+    The number of online threads is also printed in /proc/cpuinfo "siblings."
+
+  - topology_sibling_cpumask():
+
+    The cpumask contains all online threads in the core to which a thread
+    belongs.
+
+  - topology_logical_package_id():
+
+    The logical package ID to which a thread belongs.
+
+  - topology_physical_package_id():
+
+    The physical package ID to which a thread belongs.
+
+  - topology_core_id();
+
+    The ID of the core to which a thread belongs. It is also printed in /proc/cpuinfo
+    "core_id."

-x86 Topology
-============
-
-This documents and clarifies the main aspects of x86 topology modelling and
-representation in the kernel. Update/change when doing changes to the
-respective code.
-
-The architecture-agnostic topology definitions are in
-Documentation/cputopology.txt. This file holds x86-specific
-differences/specialities which must not necessarily apply to the generic
-definitions. Thus, the way to read up on Linux topology on x86 is to start
-with the generic one and look at this one in parallel for the x86 specifics.
-
-Needless to say, code should use the generic functions - this file is *only*
-here to *document* the inner workings of x86 topology.
-
-Started by Thomas Gleixner <tglx@linutronix.de> and Borislav Petkov <bp@alien8.de>.
-
-The main aim of the topology facilities is to present adequate interfaces to
-code which needs to know/query/use the structure of the running system wrt
-threads, cores, packages, etc.
-
-The kernel does not care about the concept of physical sockets because a
-socket has no relevance to software. It's an electromechanical component. In
-the past a socket always contained a single package (see below), but with the
-advent of Multi Chip Modules (MCM) a socket can hold more than one package. So
-there might be still references to sockets in the code, but they are of
-historical nature and should be cleaned up.
-
-The topology of a system is described in the units of:
-
-    - packages
-    - cores
-    - threads
-
-* Package:
-
-  Packages contain a number of cores plus shared resources, e.g. DRAM
-  controller, shared caches etc.
-
-  AMD nomenclature for package is 'Node'.
-
-  Package-related topology information in the kernel:
-
-  - cpuinfo_x86.x86_max_cores:
-
-    The number of cores in a package. This information is retrieved via CPUID.
-
-  - cpuinfo_x86.phys_proc_id:
-
-    The physical ID of the package. This information is retrieved via CPUID
-    and deduced from the APIC IDs of the cores in the package.
-
-  - cpuinfo_x86.logical_id:
-
-    The logical ID of the package. As we do not trust BIOSes to enumerate the
-    packages in a consistent way, we introduced the concept of logical package
-    ID so we can sanely calculate the number of maximum possible packages in
-    the system and have the packages enumerated linearly.
-
-  - topology_max_packages():
-
-    The maximum possible number of packages in the system. Helpful for per
-    package facilities to preallocate per package information.
-
-  - cpu_llc_id:
-
-    A per-CPU variable containing:
-    - On Intel, the first APIC ID of the list of CPUs sharing the Last Level
-    Cache
-
-    - On AMD, the Node ID or Core Complex ID containing the Last Level
-    Cache. In general, it is a number identifying an LLC uniquely on the
-    system.
-
-* Cores:
-
-  A core consists of 1 or more threads. It does not matter whether the threads
-  are SMT- or CMT-type threads.
-
-  AMDs nomenclature for a CMT core is "Compute Unit". The kernel always uses
-  "core".
-
-  Core-related topology information in the kernel:
-
-  - smp_num_siblings:
-
-    The number of threads in a core. The number of threads in a package can be
-    calculated by:
-
-	threads_per_package = cpuinfo_x86.x86_max_cores * smp_num_siblings
-
-
-* Threads:
-
-  A thread is a single scheduling unit. It's the equivalent to a logical Linux
-  CPU.
-
-  AMDs nomenclature for CMT threads is "Compute Unit Core". The kernel always
-  uses "thread".
-
-  Thread-related topology information in the kernel:
-
-  - topology_core_cpumask():
-
-    The cpumask contains all online threads in the package to which a thread
-    belongs.
-
-    The number of online threads is also printed in /proc/cpuinfo "siblings."
-
-  - topology_sibling_cpumask():
-
-    The cpumask contains all online threads in the core to which a thread
-    belongs.
-
-   - topology_logical_package_id():
-
-    The logical package ID to which a thread belongs.
-
-   - topology_physical_package_id():
-
-    The physical package ID to which a thread belongs.
-
-   - topology_core_id();
-
-    The ID of the core to which a thread belongs. It is also printed in /proc/cpuinfo
-    "core_id."

+USB Legacy support
+==================
+
+:Author: Vojtech Pavlik <vojtech@suse.cz>, January 2004
+
+
+Also known as "USB Keyboard" or "USB Mouse support" in the BIOS Setup is a
+feature that allows one to use the USB mouse and keyboard as if they were
+their classic PS/2 counterparts.  This means one can use an USB keyboard to
+type in LILO for example.
+
+It has several drawbacks, though:
+
+1) On some machines, the emulated PS/2 mouse takes over even when no USB
+   mouse is present and a real PS/2 mouse is present.  In that case the extra
+   features (wheel, extra buttons, touchpad mode) of the real PS/2 mouse may
+   not be available.
+
+2) If CONFIG_HIGHMEM64G is enabled, the PS/2 mouse emulation can cause
+   system crashes, because the SMM BIOS is not expecting to be in PAE mode.
+   The Intel E7505 is a typical machine where this happens.
+
+3) If AMD64 64-bit mode is enabled, again system crashes often happen,
+   because the SMM BIOS isn't expecting the CPU to be in 64-bit mode.  The
+   BIOS manufacturers only test with Windows, and Windows doesn't do 64-bit
+   yet.
+
+Solutions:
+
+Problem 1)
+  can be solved by loading the USB drivers prior to loading the
+  PS/2 mouse driver. Since the PS/2 mouse driver is in 2.6 compiled into
+  the kernel unconditionally, this means the USB drivers need to be
+  compiled-in, too.
+
+Problem 2)
+  can currently only be solved by either disabling HIGHMEM64G
+  in the kernel config or USB Legacy support in the BIOS. A BIOS update
+  could help, but so far no such update exists.
+
+Problem 3)
+  is usually fixed by a BIOS update. Check the board
+  manufacturers web site. If an update is not available, disable USB
+  Legacy support in the BIOS. If this alone doesn't help, try also adding
+  idle=poll on the kernel command line. The BIOS may be entering the SMM
+  on the HLT instruction as well.

+5-level paging
+==============
+
+Overview
+========
+Original x86-64 was limited by 4-level paing to 256 TiB of virtual address
+space and 64 TiB of physical address space. We are already bumping into
+this limit: some vendors offers servers with 64 TiB of memory today.
+
+To overcome the limitation upcoming hardware will introduce support for
+5-level paging. It is a straight-forward extension of the current page
+table structure adding one more layer of translation.
+
+It bumps the limits to 128 PiB of virtual address space and 4 PiB of
+physical address space. This "ought to be enough for anybody" ©.
+
+QEMU 2.9 and later support 5-level paging.
+
+Virtual memory layout for 5-level paging is described in
+Documentation/x86/x86_64/mm.txt
+
+
+Enabling 5-level paging
+=======================
+CONFIG_X86_5LEVEL=y enables the feature.
+
+Kernel with CONFIG_X86_5LEVEL=y still able to boot on 4-level hardware.
+In this case additional page table level -- p4d -- will be folded at
+runtime.
+
+User-space and large virtual address space
+==========================================
+On x86, 5-level paging enables 56-bit userspace virtual address space.
+Not all user space is ready to handle wide addresses. It's known that
+at least some JIT compilers use higher bits in pointers to encode their
+information. It collides with valid pointers with 5-level paging and
+leads to crashes.
+
+To mitigate this, we are not going to allocate virtual address space
+above 47-bit by default.
+
+But userspace can ask for allocation from full address space by
+specifying hint address (with or without MAP_FIXED) above 47-bits.
+
+If hint address set above 47-bit, but MAP_FIXED is not specified, we try
+to look for unmapped area by specified address. If it's already
+occupied, we look for unmapped area in *full* address space, rather than
+from 47-bit window.
+
+A high hint address would only affect the allocation in question, but not
+any future mmap()s.
+
+Specifying high hint address on older kernel or on machine without 5-level
+paging support is safe. The hint will be ignored and kernel will fall back
+to allocation from 47-bit address space.
+
+This approach helps to easily make application's memory allocator aware
+about large address space without manually tracking allocated virtual
+address space.
+
+One important case we need to handle here is interaction with MPX.
+MPX (without MAWA extension) cannot handle addresses above 47-bit, so we
+need to make sure that MPX cannot be enabled we already have VMA above
+the boundary and forbid creating such VMAs once MPX is enabled.

+===========================
+AMD64 Specific Boot Options
+===========================
+
+There are many others (usually documented in driver documentation), but
+only the AMD64 specific ones are listed here.
+
+Machine check
+=============
+Please see Documentation/x86/x86_64/machinecheck for sysfs runtime tunables.
+
+   mce=off
+		Disable machine check
+   mce=no_cmci
+		Disable CMCI(Corrected Machine Check Interrupt) that
+		Intel processor supports.  Usually this disablement is
+		not recommended, but it might be handy if your hardware
+		is misbehaving.
+		Note that you'll get more problems without CMCI than with
+		due to the shared banks, i.e. you might get duplicated
+		error logs.
+   mce=dont_log_ce
+		Don't make logs for corrected errors.  All events reported
+		as corrected are silently cleared by OS.
+		This option will be useful if you have no interest in any
+		of corrected errors.
+   mce=ignore_ce
+		Disable features for corrected errors, e.g. polling timer
+		and CMCI.  All events reported as corrected are not cleared
+		by OS and remained in its error banks.
+		Usually this disablement is not recommended, however if
+		there is an agent checking/clearing corrected errors
+		(e.g. BIOS or hardware monitoring applications), conflicting
+		with OS's error handling, and you cannot deactivate the agent,
+		then this option will be a help.
+   mce=no_lmce
+		Do not opt-in to Local MCE delivery. Use legacy method
+		to broadcast MCEs.
+   mce=bootlog
+		Enable logging of machine checks left over from booting.
+		Disabled by default on AMD Fam10h and older because some BIOS
+		leave bogus ones.
+		If your BIOS doesn't do that it's a good idea to enable though
+		to make sure you log even machine check events that result
+		in a reboot. On Intel systems it is enabled by default.
+   mce=nobootlog
+		Disable boot machine check logging.
+   mce=tolerancelevel[,monarchtimeout] (number,number)
+		tolerance levels:
+		0: always panic on uncorrected errors, log corrected errors
+		1: panic or SIGBUS on uncorrected errors, log corrected errors
+		2: SIGBUS or log uncorrected errors, log corrected errors
+		3: never panic or SIGBUS, log all errors (for testing only)
+		Default is 1
+		Can be also set using sysfs which is preferable.
+		monarchtimeout:
+		Sets the time in us to wait for other CPUs on machine checks. 0
+		to disable.
+   mce=bios_cmci_threshold
+		Don't overwrite the bios-set CMCI threshold. This boot option
+		prevents Linux from overwriting the CMCI threshold set by the
+		bios. Without this option, Linux always sets the CMCI
+		threshold to 1. Enabling this may make memory predictive failure
+		analysis less effective if the bios sets thresholds for memory
+		errors since we will not see details for all errors.
+   mce=recovery
+		Force-enable recoverable machine check code paths
+
+   nomce (for compatibility with i386)
+		same as mce=off
+
+   Everything else is in sysfs now.
+
+APICs
+=====
+
+   apic
+	Use IO-APIC. Default
+
+   noapic
+	Don't use the IO-APIC.
+
+   disableapic
+	Don't use the local APIC
+
+   nolapic
+     Don't use the local APIC (alias for i386 compatibility)
+
+   pirq=...
+	See Documentation/x86/i386/IO-APIC.txt
+
+   noapictimer
+	Don't set up the APIC timer
+
+   no_timer_check
+	Don't check the IO-APIC timer. This can work around
+	problems with incorrect timer initialization on some boards.
+
+   apicpmtimer
+	Do APIC timer calibration using the pmtimer. Implies
+	apicmaintimer. Useful when your PIT timer is totally broken.
+
+Timing
+======
+
+  notsc
+    Deprecated, use tsc=unstable instead.
+
+  nohpet
+    Don't use the HPET timer.
+
+Idle loop
+=========
+
+  idle=poll
+    Don't do power saving in the idle loop using HLT, but poll for rescheduling
+    event. This will make the CPUs eat a lot more power, but may be useful
+    to get slightly better performance in multiprocessor benchmarks. It also
+    makes some profiling using performance counters more accurate.
+    Please note that on systems with MONITOR/MWAIT support (like Intel EM64T
+    CPUs) this option has no performance advantage over the normal idle loop.
+    It may also interact badly with hyperthreading.
+
+Rebooting
+=========
+
+   reboot=b[ios] | t[riple] | k[bd] | a[cpi] | e[fi] [, [w]arm | [c]old]
+      bios
+        Use the CPU reboot vector for warm reset
+      warm
+        Don't set the cold reboot flag
+      cold
+        Set the cold reboot flag
+      triple
+        Force a triple fault (init)
+      kbd
+        Use the keyboard controller. cold reset (default)
+      acpi
+        Use the ACPI RESET_REG in the FADT. If ACPI is not configured or
+        the ACPI reset does not work, the reboot path attempts the reset
+        using the keyboard controller.
+      efi
+        Use efi reset_system runtime service. If EFI is not configured or
+        the EFI reset does not work, the reboot path attempts the reset using
+        the keyboard controller.
+
+   Using warm reset will be much faster especially on big memory
+   systems because the BIOS will not go through the memory check.
+   Disadvantage is that not all hardware will be completely reinitialized
+   on reboot so there may be boot problems on some systems.
+
+   reboot=force
+     Don't stop other CPUs on reboot. This can make reboot more reliable
+     in some cases.
+
+Non Executable Mappings
+=======================
+
+  noexec=on|off
+    on
+      Enable(default)
+    off
+      Disable
+
+NUMA
+====
+
+  numa=off
+    Only set up a single NUMA node spanning all memory.
+
+  numa=noacpi
+    Don't parse the SRAT table for NUMA setup
+
+  numa=fake=<size>[MG]
+    If given as a memory unit, fills all system RAM with nodes of
+    size interleaved over physical nodes.
+
+  numa=fake=<N>
+    If given as an integer, fills all system RAM with N fake nodes
+    interleaved over physical nodes.
+
+  numa=fake=<N>U
+    If given as an integer followed by 'U', it will divide each
+    physical node into N emulated nodes.
+
+ACPI
+====
+
+  acpi=off
+    Don't enable ACPI
+  acpi=ht
+    Use ACPI boot table parsing, but don't enable ACPI interpreter
+  acpi=force
+    Force ACPI on (currently not needed)
+  acpi=strict
+    Disable out of spec ACPI workarounds.
+  acpi_sci={edge,level,high,low}
+    Set up ACPI SCI interrupt.
+  acpi=noirq
+    Don't route interrupts
+  acpi=nocmcff
+    Disable firmware first mode for corrected errors. This
+    disables parsing the HEST CMC error source to check if
+    firmware has set the FF flag. This may result in
+    duplicate corrected error reports.
+
+PCI
+===
+
+  pci=off
+    Don't use PCI
+  pci=conf1
+    Use conf1 access.
+  pci=conf2
+    Use conf2 access.
+  pci=rom
+    Assign ROMs.
+  pci=assign-busses
+    Assign busses
+  pci=irqmask=MASK
+    Set PCI interrupt mask to MASK
+  pci=lastbus=NUMBER
+    Scan up to NUMBER busses, no matter what the mptable says.
+  pci=noacpi
+    Don't use ACPI to set up PCI interrupt routing.
+
+IOMMU (input/output memory management unit)
+===========================================
+Multiple x86-64 PCI-DMA mapping implementations exist, for example:
+
+   1. <lib/dma-direct.c>: use no hardware/software IOMMU at all
+      (e.g. because you have < 3 GB memory).
+      Kernel boot message: "PCI-DMA: Disabling IOMMU"
+
+   2. <arch/x86/kernel/amd_gart_64.c>: AMD GART based hardware IOMMU.
+      Kernel boot message: "PCI-DMA: using GART IOMMU"
+
+   3. <arch/x86_64/kernel/pci-swiotlb.c> : Software IOMMU implementation. Used
+      e.g. if there is no hardware IOMMU in the system and it is need because
+      you have >3GB memory or told the kernel to us it (iommu=soft))
+      Kernel boot message: "PCI-DMA: Using software bounce buffering
+      for IO (SWIOTLB)"
+
+   4. <arch/x86_64/pci-calgary.c> : IBM Calgary hardware IOMMU. Used in IBM
+      pSeries and xSeries servers. This hardware IOMMU supports DMA address
+      mapping with memory protection, etc.
+      Kernel boot message: "PCI-DMA: Using Calgary IOMMU"
+
+::
+
+  iommu=[<size>][,noagp][,off][,force][,noforce]
+  [,memaper[=<order>]][,merge][,fullflush][,nomerge]
+  [,noaperture][,calgary]
+
+General iommu options:
+
+    off
+      Don't initialize and use any kind of IOMMU.
+    noforce
+      Don't force hardware IOMMU usage when it is not needed. (default).
+    force
+      Force the use of the hardware IOMMU even when it is
+      not actually needed (e.g. because < 3 GB memory).
+    soft
+      Use software bounce buffering (SWIOTLB) (default for
+      Intel machines). This can be used to prevent the usage
+      of an available hardware IOMMU.
+
+iommu options only relevant to the AMD GART hardware IOMMU:
+
+    <size>
+      Set the size of the remapping area in bytes.
+    allowed
+      Overwrite iommu off workarounds for specific chipsets.
+    fullflush
+      Flush IOMMU on each allocation (default).
+    nofullflush
+      Don't use IOMMU fullflush.
+    memaper[=<order>]
+      Allocate an own aperture over RAM with size 32MB<<order.
+      (default: order=1, i.e. 64MB)
+    merge
+      Do scatter-gather (SG) merging. Implies "force" (experimental).
+    nomerge
+      Don't do scatter-gather (SG) merging.
+    noaperture
+      Ask the IOMMU not to touch the aperture for AGP.
+    noagp
+      Don't initialize the AGP driver and use full aperture.
+    panic
+      Always panic when IOMMU overflows.
+    calgary
+      Use the Calgary IOMMU if it is available
+
+iommu options only relevant to the software bounce buffering (SWIOTLB) IOMMU
+implementation:
+
+    swiotlb=<pages>[,force]
+      <pages>
+        Prereserve that many 128K pages for the software IO bounce buffering.
+      force
+        Force all IO through the software TLB.
+
+Settings for the IBM Calgary hardware IOMMU currently found in IBM
+pSeries and xSeries machines
+
+    calgary=[64k,128k,256k,512k,1M,2M,4M,8M]
+      Set the size of each PCI slot's translation table when using the
+      Calgary IOMMU. This is the size of the translation table itself
+      in main memory. The smallest table, 64k, covers an IO space of
+      32MB; the largest, 8MB table, can cover an IO space of 4GB.
+      Normally the kernel will make the right choice by itself.
+    calgary=[translate_empty_slots]
+      Enable translation even on slots that have no devices attached to
+      them, in case a device will be hotplugged in the future.
+    calgary=[disable=<PCI bus number>]
+      Disable translation on a given PHB. For
+      example, the built-in graphics adapter resides on the first bridge
+      (PCI bus number 0); if translation (isolation) is enabled on this
+      bridge, X servers that access the hardware directly from user
+      space might stop working. Use this option if you have devices that
+      are accessed from userspace directly on some PCI host bridge.
+    panic
+      Always panic when IOMMU overflows
+
+
+Miscellaneous
+=============
+
+  nogbpages
+    Do not use GB pages for kernel direct mappings.
+  gbpages
+    Use GB pages for kernel direct mappings.

-Firmware support for CPU hotplug under Linux/x86-64
----------------------------------------------------
-
-Linux/x86-64 supports CPU hotplug now. For various reasons Linux wants to
-know in advance of boot time the maximum number of CPUs that could be plugged
-into the system. ACPI 3.0 currently has no official way to supply
-this information from the firmware to the operating system.
-
-In ACPI each CPU needs an LAPIC object in the MADT table (5.2.11.5 in the
-ACPI 3.0 specification).  ACPI already has the concept of disabled LAPIC
-objects by setting the Enabled bit in the LAPIC object to zero.
-
-For CPU hotplug Linux/x86-64 expects now that any possible future hotpluggable
-CPU is already available in the MADT. If the CPU is not available yet
-it should have its LAPIC Enabled bit set to 0. Linux will use the number
-of disabled LAPICs to compute the maximum number of future CPUs.
-
-In the worst case the user can overwrite this choice using a command line
-option (additional_cpus=...), but it is recommended to supply the correct
-number (or a reasonable approximation of it, with erring towards more not less)
-in the MADT to avoid manual configuration.

-Using numa=fake and CPUSets for Resource Management
-Written by David Rientjes <rientjes@cs.washington.edu>
-
-This document describes how the numa=fake x86_64 command-line option can be used
-in conjunction with cpusets for coarse memory management.  Using this feature,
-you can create fake NUMA nodes that represent contiguous chunks of memory and
-assign them to cpusets and their attached tasks.  This is a way of limiting the
-amount of system memory that are available to a certain class of tasks.
-
-For more information on the features of cpusets, see
-Documentation/cgroup-v1/cpusets.txt.
-There are a number of different configurations you can use for your needs.  For
-more information on the numa=fake command line option and its various ways of
-configuring fake nodes, see Documentation/x86/x86_64/boot-options.txt.
-
-For the purposes of this introduction, we'll assume a very primitive NUMA
-emulation setup of "numa=fake=4*512,".  This will split our system memory into
-four equal chunks of 512M each that we can now use to assign to cpusets.  As
-you become more familiar with using this combination for resource control,
-you'll determine a better setup to minimize the number of nodes you have to deal
-with.
-
-A machine may be split as follows with "numa=fake=4*512," as reported by dmesg:
-
-	Faking node 0 at 0000000000000000-0000000020000000 (512MB)
-	Faking node 1 at 0000000020000000-0000000040000000 (512MB)
-	Faking node 2 at 0000000040000000-0000000060000000 (512MB)
-	Faking node 3 at 0000000060000000-0000000080000000 (512MB)
-	...
-	On node 0 totalpages: 130975
-	On node 1 totalpages: 131072
-	On node 2 totalpages: 131072
-	On node 3 totalpages: 131072
-
-Now following the instructions for mounting the cpusets filesystem from
-Documentation/cgroup-v1/cpusets.txt, you can assign fake nodes (i.e. contiguous memory
-address spaces) to individual cpusets:
-
-	[root@xroads /]# mkdir exampleset
-	[root@xroads /]# mount -t cpuset none exampleset
-	[root@xroads /]# mkdir exampleset/ddset
-	[root@xroads /]# cd exampleset/ddset
-	[root@xroads /exampleset/ddset]# echo 0-1 > cpus
-	[root@xroads /exampleset/ddset]# echo 0-1 > mems
-
-Now this cpuset, 'ddset', will only allowed access to fake nodes 0 and 1 for
-memory allocations (1G).
-
-You can now assign tasks to these cpusets to limit the memory resources
-available to them according to the fake nodes assigned as mems:
-
-	[root@xroads /exampleset/ddset]# echo $$ > tasks
-	[root@xroads /exampleset/ddset]# dd if=/dev/zero of=tmp bs=1024 count=1G
-	[1] 13425
-
-Notice the difference between the system memory usage as reported by
-/proc/meminfo between the restricted cpuset case above and the unrestricted
-case (i.e. running the same 'dd' command without assigning it to a fake NUMA
-cpuset):
-				Unrestricted	Restricted
-	MemTotal:		3091900 kB	3091900 kB
-	MemFree:		  42113 kB	1513236 kB
-

+Architecture defines a 64-bit virtual address. Implementations can support
+less. Currently supported are 48- and 57-bit virtual addresses. Bits 63
+through to the most-significant implemented bit are sign extended.
+This causes hole between user space and kernel addresses if you interpret them
+as unsigned.
+
+The direct mapping covers all memory in the system up to the highest
+memory address (this means in some cases it can also include PCI memory
+holes).
+
+vmalloc space is lazily synchronized into the different PML4/PML5 pages of
+the processes using the page fault handler, with init_top_pgt as
+reference.
+
+We map EFI runtime services in the 'efi_pgd' PGD in a 64Gb large virtual
+memory window (this size is arbitrary, it can be raised later if needed).
+The mappings are not part of any other kernel PGD and are only available
+during EFI runtime calls.
+
+Note that if CONFIG_RANDOMIZE_MEMORY is enabled, the direct mapping of all
+physical memory, vmalloc/ioremap space and virtual memory map are randomized.
+Their order is preserved but their base will be offset early at boot time.
+
+Be very careful vs. KASLR when changing anything here. The KASLR address
+range must not overlap with anything except the KASAN shadow area, which is
+correct as KASAN disables KASLR.
+
+For both 4- and 5-level layouts, the STACKLEAK_POISON value in the last 2MB
+hole: ffffffffffff4111

-
-Notes:
-
- - Negative addresses such as "-23 TB" are absolute addresses in bytes, counted down
-   from the top of the 64-bit address space. It's easier to understand the layout
-   when seen both in absolute addresses and in distance-from-top notation.
-
-   For example 0xffffe90000000000 == -23 TB, it's 23 TB lower than the top of the
-   64-bit address space (ffffffffffffffff).
-
-   Note that as we get closer to the top of the address space, the notation changes
-   from TB to GB and then MB/KB.
-
- - "16M TB" might look weird at first sight, but it's an easier to visualize size
-   notation than "16 EB", which few will recognize at first sight as 16 exabytes.
-   It also shows it nicely how incredibly large 64-bit address space is.

-Architecture defines a 64-bit virtual address. Implementations can support
-less. Currently supported are 48- and 57-bit virtual addresses. Bits 63
-through to the most-significant implemented bit are sign extended.
-This causes hole between user space and kernel addresses if you interpret them
-as unsigned.
-
-The direct mapping covers all memory in the system up to the highest
-memory address (this means in some cases it can also include PCI memory
-holes).
-
-vmalloc space is lazily synchronized into the different PML4/PML5 pages of
-the processes using the page fault handler, with init_top_pgt as
-reference.
-
-We map EFI runtime services in the 'efi_pgd' PGD in a 64Gb large virtual
-memory window (this size is arbitrary, it can be raised later if needed).
-The mappings are not part of any other kernel PGD and are only available
-during EFI runtime calls.
-
-Note that if CONFIG_RANDOMIZE_MEMORY is enabled, the direct mapping of all
-physical memory, vmalloc/ioremap space and virtual memory map are randomized.
-Their order is preserved but their base will be offset early at boot time.
-
-Be very careful vs. KASLR when changing anything here. The KASLR address
-range must not overlap with anything except the KASAN shadow area, which is
-correct as KASAN disables KASLR.

  * this will result in random numbers that are merely cryptographically
  * strong.  For many applications, however, this is acceptable.
  *
+ * Exported interfaces ---- kernel output
+ * --------------------------------------
+ *
+ * The primary kernel interface is
+ *
+ * 	void get_random_bytes(void *buf, int nbytes);
+ *
+ * This interface will return the requested number of random bytes,
+ * and place it in the requested buffer.  This is equivalent to a
+ * read from /dev/urandom.
+ *
+ * For less critical applications, there are the functions:
+ *
+ * 	u32 get_random_u32()
+ * 	u64 get_random_u64()
+ * 	unsigned int get_random_int()
+ * 	unsigned long get_random_long()
+ *
+ * These are produced by a cryptographic RNG seeded from get_random_bytes,
+ * and so do not deplete the entropy pool as much.  These are recommended
+ * for most in-kernel operations *if the result is going to be stored in
+ * the kernel*.
+ *
+ * Specifically, the get_random_int() family do not attempt to do
+ * "anti-backtracking".  If you capture the state of the kernel (e.g.
+ * by snapshotting the VM), you can figure out previous get_random_int()
+ * return values.  But if the value is stored in the kernel anyway,
+ * this is not a problem.
+ *
+ * It *is* safe to expose get_random_int() output to attackers (e.g. as
+ * network cookies); given outputs 1..n, it's not feasible to predict
+ * outputs 0 or n+1.  The only concern is an attacker who breaks into
+ * the kernel later; the get_random_int() engine is not reseeded as
+ * often as the get_random_bytes() one.
+ *
+ * get_random_bytes() is needed for keys that need to stay secret after
+ * they are erased from the kernel.  For example, any key that will
+ * be wrapped and stored encrypted.  And session encryption keys: we'd
+ * like to know that after the session is closed and the keys erased,
+ * the plaintext is unrecoverable to someone who recorded the ciphertext.
+ *
+ * But for network ports/cookies, stack canaries, PRNG seeds, address
+ * space layout randomization, session *authentication* keys, or other
+ * applications where the sensitive data is stored in the kernel in
+ * plaintext for as long as it's sensitive, the get_random_int() family
+ * is just fine.
+ *
+ * Consider ASLR.  We want to keep the address space secret from an
+ * outside attacker while the process is running, but once the address
+ * space is torn down, it's of no use to an attacker any more.  And it's
+ * stored in kernel data structures as long as it's alive, so worrying
+ * about an attacker's ability to extrapolate it from the get_random_int()
+ * CRNG is silly.
+ *
+ * Even some cryptographic keys are safe to generate with get_random_int().
+ * In particular, keys for SipHash are generally fine.  Here, knowledge
+ * of the key authorizes you to do something to a kernel object (inject
+ * packets to a network connection, or flood a hash table), and the
+ * key is stored with the object being protected.  Once it goes away,
+ * we no longer care if anyone knows the key.
+ *
+ * prandom_u32()
+ * -------------
+ *
+ * For even weaker applications, see the pseudorandom generator
+ * prandom_u32(), prandom_max(), and prandom_bytes().  If the random
+ * numbers aren't security-critical at all, these are *far* cheaper.
+ * Useful for self-tests, random error simulation, randomized backoffs,
+ * and any other application where you trust that nobody is trying to
+ * maliciously mess with you by guessing the "random" numbers.

+ * clk_core_get - Find the clk_core parent of a clk
+ * @core: clk to find parent of
+ * @p_index: parent index to search for
+ *
+ * This is the preferred method for clk providers to find the parent of a
+ * clk when that parent is external to the clk controller. The parent_names
+ * array is indexed and treated as a local name matching a string in the device
+ * node's 'clock-names' property or as the 'con_id' matching the device's
+ * dev_name() in a clk_lookup. This allows clk providers to use their own
+ * namespace instead of looking for a globally unique parent string.
+ *
+ * For example the following DT snippet would allow a clock registered by the
+ * clock-controller@c001 that has a clk_init_data::parent_data array
+ * with 'xtal' in the 'name' member to find the clock provided by the
+ * clock-controller@f00abcd without needing to get the globally unique name of
+ * the xtal clk.
+ *
+ *      parent: clock-controller@f00abcd {
+ *              reg = <0xf00abcd 0xabcd>;

- * We're configured to use a specific TC block, one that's not hooked

- *
- *   - Two channels combine to create a free-running 32 bit counter
- *     with a base rate of 5+ MHz, packaged as a clocksource (with
- *     resolution better than 200 nsec).
- *   - Some chips support 32 bit counter. A single channel is used for
- *     this 32 bit free-running counter. the second channel is not used.
- *
- *   - The third channel may be used to provide a 16-bit clockevent
- *     source, used in either periodic or oneshot mode.  This runs
- *     at 32 KiHZ, and can handle delays of up to two seconds.

+ * DOC: ras debugfs control interface
+ *
+ * It accepts struct ras_debug_if who has two members.
+ *
+ * First member: ras_debug_if::head or ras_debug_if::inject.
+ *
+ * head is used to indicate which IP block will be under control.
+ *
+ * head has four members, they are block, type, sub_block_index, name.
+ * block: which IP will be under control.
+ * type: what kind of error will be enabled/disabled/injected.
+ * sub_block_index: some IPs have subcomponets. say, GFX, sDMA.
+ * name: the name of IP.
+ *
+ * inject has two more members than head, they are address, value.
+ * As their names indicate, inject operation will write the
+ * value to the address.
+ *
+ * Second member: struct ras_debug_if::op.
+ * It has three kinds of operations.
+ *  0: disable RAS on the block. Take ::head as its data.
+ *  1: enable RAS on the block. Take ::head as its data.
+ *  2: inject errors on the block. Take ::inject as its data.
+ *
+ * How to use the interface?
+ * programs:
+ * copy the struct ras_debug_if in your codes and initialize it.
+ * write the struct to the control node.
+ *
+ * bash:
+ * echo op block [error [address value]] > .../ras/ras_ctrl
+ *	op: disable, enable, inject
+ *		disable: only block is needed
+ *		enable: block and error are needed
+ *		inject: error, address, value are needed
+ *	block: umc, smda, gfx, .........
+ *		see ras_block_string[] for details
+ *	error: ue, ce
+ *		ue: multi_uncorrectable
+ *		ce: single_correctable
+ *
+ * here are some examples for bash commands,
+ *	echo inject umc ue 0x0 0x0 > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ *	echo inject umc ce 0 0 > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ *	echo disable umc > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ *
+ * How to check the result?
+ *
+ * For disable/enable, please check ras features at
+ * /sys/class/drm/card[0/1/2...]/device/ras/features
+ *
+ * For inject, please check corresponding err count at
+ * /sys/class/drm/card[0/1/2...]/device/ras/[gfx/sdma/...]_err_count
+ *
+ * NOTE: operation is only allowed on blocks which are supported.
+ * Please check ras mask at /sys/module/amdgpu/parameters/ras_mask

+ *
+ * The big boss (CRTC) is for pipeline assignment, since &komeda_component isn't
+ * independent and can be assigned to CRTC freely, but belongs to a specific
+ * pipeline, only pipeline can be shared between crtc, and pipeline as a whole
+ * (include all the internal components) assigned to a specific CRTC.
+ *
+ * So when set a user to komeda_component, need first to check the status of
+ * component->pipeline to see if the pipeline is available on this specific
+ * CRTC. if the pipeline is busy (assigned to another CRTC), even the required
+ * component is free, the component still cannot be assigned to the direct user.

+/**
+ * DOC: ASPEED GFX Driver
+ *
+ * This driver is for the ASPEED BMC SoC's 'GFX' display hardware, also called
+ * the 'SOC Display Controller' in the datasheet. This driver runs on the ARM
+ * based BMC systems, unlike the ast driver which runs on a host CPU and is for
+ * a PCIe graphics device.
+ *
+ * The AST2500 supports a total of 3 output paths:
+ *
+ *   1. VGA output, the output target can choose either or both to the DAC
+ *   or DVO interface.
+ *
+ *   2. Graphics CRT output, the output target can choose either or both to
+ *   the DAC or DVO interface.
+ *
+ *   3. Video input from DVO, the video input can be used for video engine
+ *   capture or DAC display output.
+ *
+ * Output options are selected in SCU2C.
+ *
+ * The "VGA mode" device is the PCI attached controller. The "Graphics CRT"
+ * is the ARM's internal display controller.
+ *
+ * The driver only supports a simple configuration consisting of a 40MHz
+ * pixel clock, fixed by hardware limitations, and the VGA output path.
+ *
+ * The driver was written with the 'AST2500 Software Programming Guide' v17,
+ * which is available under NDA from ASPEED.

 /**
+ * DOC: component helper usage recommendations
+ *
+ * DRM drivers that drive hardware where a logical device consists of a pile of
+ * independent hardware blocks are recommended to use the :ref:`component helper
+ * library<component>`. For consistency and better options for code reuse the
+ * following guidelines apply:
+ *
+ *  - The entire device initialization procedure should be run from the
+ *    &component_master_ops.master_bind callback, starting with drm_dev_init(),
+ *    then binding all components with component_bind_all() and finishing with
+ *    drm_dev_register().
+ *
+ *  - The opaque pointer passed to all components through component_bind_all()
+ *    should point at &struct drm_device of the device instance, not some driver
+ *    specific private structure.
+ *
+ *  - The component helper fills the niche where further standardization of
+ *    interfaces is not practical. When there already is, or will be, a
+ *    standardized interface like &drm_bridge or &drm_panel, providing its own
+ *    functions to find such components at driver load time, like
+ *    drm_of_find_panel_or_bridge(), then the component helper should not be
+ *    used.

+- Thermal support.
+
+- Bifrost support:
+  - DT bindings (Neil, WIP)
+  - MMU page table format and address space setup
+  - Bifrost specific feature and issue handling
+  - Coherent DMA support
+
+- Support for 2MB pages. The io-pgtable code already supports this. Finishing
+  support involves either copying or adapting the iommu API to handle passing
+  aligned addresses and sizes to the io-pgtable code.
+
+- Per FD address space support. The h/w supports multiple addresses spaces.
+  The hard part is handling when more address spaces are needed than what
+  the h/w provides.
+
+- Support pinning pages on demand (GPU page faults).
+
+- Support userspace controlled GPU virtual addresses. Needed for Vulkan. (Tomeu)
+
+- Support for madvise and a shrinker.
+
+- Compute job support. So called 'compute only' jobs need to be plumbed up to
+  userspace.
+
+- Performance counter support. (Boris)

-	 * empty and STOP condition has been sent.
-	 * Consequently, we should enable NACK interrupt rather than TXCOMP to
-	 * detect transmission failure.
-	 * Indeed let's take the case of an i2c write command using DMA.
-	 * Whenever the slave doesn't acknowledge a byte, the LOCK, NACK and
-	 * TXCOMP bits are set together into the Status Register.
-	 * LOCK is a clear on write bit, which is set to prevent the DMA
-	 * controller from sending new data on the i2c bus after a NACK
-	 * condition has happened. Once locked, this i2c peripheral stops
-	 * triggering the DMA controller for new data but it is more than
-	 * likely that a new DMA transaction is already in progress, writing
-	 * into the Transmit Holding Register. Since the peripheral is locked,
-	 * these new data won't be sent to the i2c bus but they will remain
-	 * into the Transmit Holding Register, so TXCOMP bit is cleared.
-	 * Then when the interrupt handler is called, the Status Register is
-	 * read: the TXCOMP bit is clear but NACK bit is still set. The driver
-	 * manage the error properly, without waiting for timeout.
-	 * This case can be reproduced easyly when writing into an at24 eeprom.
-	 *
-	 * Besides, the TXCOMP bit is already set before the i2c transaction
-	 * has been started. For read transactions, this bit is cleared when
-	 * writing the START bit into the Control Register. So the
-	 * corresponding interrupt can safely be enabled just after.
-	 * However for write transactions managed by the CPU, we first write
-	 * into THR, so TXCOMP is cleared. Then we can safely enable TXCOMP
-	 * interrupt. If TXCOMP interrupt were enabled before writing into THR,
-	 * the interrupt handler would be called immediately and the i2c command
-	 * would be reported as completed.
-	 * Also when a write transaction is managed by the DMA controller,
-	 * enabling the TXCOMP interrupt in this function may lead to a race
-	 * condition since we don't know whether the TXCOMP interrupt is enabled
-	 * before or after the DMA has started to write into THR. So the TXCOMP
-	 * interrupt is enabled later by at91_twi_write_data_dma_callback().
-	 * Immediately after in that DMA callback, if the alternative command
-	 * mode is not used, we still need to send the STOP condition manually
-	 * writing the corresponding bit into the Control Register.

+	 * Indeed let's take the case of an i2c write command using DMA.
+	 * Whenever the slave doesn't acknowledge a byte, the LOCK, NACK and
+	 * TXCOMP bits are set together into the Status Register.
+	 * LOCK is a clear on write bit, which is set to prevent the DMA
+	 * controller from sending new data on the i2c bus after a NACK
+	 * condition has happened. Once locked, this i2c peripheral stops
+	 * triggering the DMA controller for new data but it is more than
+	 * likely that a new DMA transaction is already in progress, writing
+	 * into the Transmit Holding Register. Since the peripheral is locked,
+	 * these new data won't be sent to the i2c bus but they will remain
+	 * into the Transmit Holding Register, so TXCOMP bit is cleared.
+	 * Then when the interrupt handler is called, the Status Register is
+	 * read: the TXCOMP bit is clear but NACK bit is still set. The driver
+	 * manage the error properly, without waiting for timeout.
+	 * This case can be reproduced easyly when writing into an at24 eeprom.
+	 *
+	 * Besides, the TXCOMP bit is already set before the i2c transaction
+	 * has been started. For read transactions, this bit is cleared when
+	 * writing the START bit into the Control Register. So the
+	 * corresponding interrupt can safely be enabled just after.
+	 * However for write transactions managed by the CPU, we first write
+	 * into THR, so TXCOMP is cleared. Then we can safely enable TXCOMP
+	 * interrupt. If TXCOMP interrupt were enabled before writing into THR,
+	 * the interrupt handler would be called immediately and the i2c command
+	 * would be reported as completed.
+	 * Also when a write transaction is managed by the DMA controller,
+	 * enabling the TXCOMP interrupt in this function may lead to a race
+	 * condition since we don't know whether the TXCOMP interrupt is enabled
+	 * before or after the DMA has started to write into THR. So the TXCOMP
+	 * interrupt is enabled later by at91_twi_write_data_dma_callback().
+	 * Immediately after in that DMA callback, if the alternative command
+	 * mode is not used, we still need to send the STOP condition manually
+	 * writing the corresponding bit into the Control Register.

-	  Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and
-	  also clears the counter's respective error flag. Although the counters
-	  have a 25-bit range, only the lower 24 bits may be set, either directly
-	  or via a counter's preset attribute. Interrupts are not supported by
-	  this driver.

-	  On DiskOnChip devices shipped with the INFTL filesystem (Millennium

-	  device for the Bad Block Table (BBT).  If you have existing INFTL
-	  data on your device (created by non-Linux tools such as M-Systems'
-	  DOS drivers), your data might overlap the area Linux wants to use for
-	  the BBT.  If this is a concern for you, leave this option disabled and
-	  Linux will not write BBT data into this area.
-	  The downside of leaving this option disabled is that if bad blocks
-	  are detected by Linux, they will not be recorded in the BBT, which
-	  could cause future problems.
-	  Once you enable this option, new filesystems (INFTL or others, created
-	  in Linux or other operating systems) will not use the reserved area.
-	  The only reason not to enable this option is to prevent damage to
-	  preexisting filesystems.
-	  Even if you leave this disabled, you can enable BBT writes at module

+	  On DiskOnChip devices shipped with the INFTL filesystem (Millennium
+	  and 2000 TSOP/Alon), Linux reserves some space at the end of the
+	  device for the Bad Block Table (BBT).  If you have existing INFTL
+	  data on your device (created by non-Linux tools such as M-Systems'
+	  DOS drivers), your data might overlap the area Linux wants to use for
+	  the BBT.  If this is a concern for you, leave this option disabled and
+	  Linux will not write BBT data into this area.
+	  The downside of leaving this option disabled is that if bad blocks
+	  are detected by Linux, they will not be recorded in the BBT, which
+	  could cause future problems.
+	  Once you enable this option, new filesystems (INFTL or others, created
+	  in Linux or other operating systems) will not use the reserved area.
+	  The only reason not to enable this option is to prevent damage to
+	  preexisting filesystems.
+	  Even if you leave this disabled, you can enable BBT writes at module
+	  load time (assuming you build diskonchip as a module) with the module
+	  parameter "inftl_bbt_write=1".
