+Indirect Target Selection (ITS)
+===============================
+
+ITS is a vulnerability in some Intel CPUs that support Enhanced IBRS and were
+released before Alder Lake. ITS may allow an attacker to control the prediction
+of indirect branches and RETs located in the lower half of a cacheline.
+
+ITS is assigned CVE-2024-28956 with a CVSS score of 4.7 (Medium).
+
+Scope of Impact
+---------------
+- **eIBRS Guest/Host Isolation**: Indirect branches in KVM/kernel may still be
+  predicted with unintended target corresponding to a branch in the guest.
+
+- **Intra-Mode BTI**: In-kernel training such as through cBPF or other native
+  gadgets.
+
+- **Indirect Branch Prediction Barrier (IBPB)**: After an IBPB, indirect
+  branches may still be predicted with targets corresponding to direct branches
+  executed prior to the IBPB. /*(DEBLOBBED)*/

+- All affected CPUs enumerate Enhanced IBRS feature.
+- IBPB isolation is affected on all ITS affected CPUs, and need a microcode
+  update for mitigation.
+- None of the affected CPUs enumerate BHI_CTRL which was introduced in Golden
+  Cove (Alder Lake and Sapphire Rapids). This can help guests to determine the
+  host's affected status.
+- Intel Atom CPUs are not affected by ITS.
+
+Mitigation
+----------
+As only the indirect branches and RETs that have their last byte of instruction
+in the lower half of the cacheline are vulnerable to ITS, the basic idea behind
+the mitigation is to not allow indirect branches in the lower half.
+
+This is achieved by relying on existing retpoline support in the kernel, and in
+compilers. ITS-vulnerable retpoline sites are runtime patched to point to newly
+added ITS-safe thunks. These safe thunks consists of indirect branch in the
+second half of the cacheline. Not all retpoline sites are patched to thunks, if
+a retpoline site is evaluated to be ITS-safe, it is replaced with an inline
+indirect branch.
+
+Dynamic thunks
+~~~~~~~~~~~~~~
+From a dynamically allocated pool of safe-thunks, each vulnerable site is
+replaced with a new thunk, such that they get a unique address. This could
+improve the branch prediction accuracy. Also, it is a defense-in-depth measure
+against aliasing.
+
+Note, for simplicity, indirect branches in eBPF programs are always replaced
+with a jump to a static thunk in __x86_indirect_its_thunk_array. If required,
+in future this can be changed to use dynamic thunks.
+
+All vulnerable RETs are replaced with a static thunk, they do not use dynamic
+thunks. This is because RETs get their prediction from RSB mostly that does not
+depend on source address. RETs that underflow RSB may benefit from dynamic
+thunks. But, RETs significantly outnumber indirect branches, and any benefit
+from a unique source address could be outweighed by the increased icache
+footprint and iTLB pressure.
+
+Retpoline
+~~~~~~~~~
+Retpoline sequence also mitigates ITS-unsafe indirect branches. For this
+reason, when retpoline is enabled, ITS mitigation only relocates the RETs to
+safe thunks. Unless user requested the RSB-stuffing mitigation.
+
+RSB Stuffing
+~~~~~~~~~~~~
+RSB-stuffing via Call Depth Tracking is a mitigation for Retbleed RSB-underflow
+attacks. And it also mitigates RETs that are vulnerable to ITS.
+
+Mitigation in guests
+^^^^^^^^^^^^^^^^^^^^
+All guests deploy ITS mitigation by default, irrespective of eIBRS enumeration
+and Family/Model of the guest. This is because eIBRS feature could be hidden
+from a guest. One exception to this is when a guest enumerates BHI_DIS_S, which
+indicates that the guest is running on an unaffected host.
+
+To prevent guests from unnecessarily deploying the mitigation on unaffected
+platforms, Intel has defined ITS_NO bit(62) in MSR IA32_ARCH_CAPABILITIES. When

+
+   off      Disable ITS mitigation.
+
+   vmexit   Equivalent to "=on" if the CPU is affected by guest/host isolation

+   stuff    Deploy RSB-fill mitigation when retpoline is also deployed.

+
+VMSCAPE
+=======
+
+VMSCAPE is a vulnerability that may allow a guest to influence the branch
+prediction in host userspace. It particularly affects hypervisors like QEMU.
+
+Even if a hypervisor may not have any sensitive data like disk encryption keys,
+guest-userspace may be able to attack the guest-kernel using the hypervisor as
+a confused deputy.
+
+Affected processors
+-------------------
+
+The following CPU families are affected by VMSCAPE:
+
+**Intel processors:**
+  - Skylake generation (Parts without Enhanced-IBRS)
+  - Cascade Lake generation - (Parts affected by ITS guest/host separation)
+  - Alder Lake and newer (Parts affected by BHI)
+
+Note that, BHI affected parts that use BHB clearing software mitigation e.g.
+Icelake are not vulnerable to VMSCAPE.
+
+**AMD processors:**
+  - Zen series (families 0x17, 0x19, 0x1a)
+
+** Hygon processors:**
+ - Family 0x18
+
+Mitigation
+----------
+
+Conditional IBPB
+----------------
+
+Kernel tracks when a CPU has run a potentially malicious guest and issues an
+IBPB before the first exit to userspace after VM-exit. If userspace did not run
+between VM-exit and the next VM-entry, no IBPB is issued.
+
+Note that the existing userspace mitigation against Spectre-v2 is effective in
+protecting the userspace. They are insufficient to protect the userspace VMMs
+from a malicious guest. This is because Spectre-v2 mitigations are applied at
+context switch time, while the userspace VMM can run after a VM-exit without a
+context switch.
+
+Vulnerability enumeration and mitigation is not applied inside a guest. This is
+because nested hypervisors should already be deploying IBPB to isolate
+themselves from nested guests.
+
+SMT considerations
+------------------
+
+When Simultaneous Multi-Threading (SMT) is enabled, hypervisors can be
+vulnerable to cross-thread attacks. For complete protection against VMSCAPE
+attacks in SMT environments, STIBP should be enabled.
+
+The kernel will issue a warning if SMT is enabled without adequate STIBP
+protection. Warning is not issued when:
+
+- SMT is disabled
+- STIBP is enabled system-wide
+- Intel eIBRS is enabled (which implies STIBP protection)
+
+System information and options
+------------------------------
+
+The sysfs file showing VMSCAPE mitigation status is:
+
+  /sys/devices/system/cpu/vulnerabilities/vmscape
+
+The possible values in this file are:
+
+ * 'Not affected':
+
+   The processor is not vulnerable to VMSCAPE attacks.
+
+ * 'Vulnerable':
+
+   The processor is vulnerable and no mitigation has been applied.
+
+ * 'Mitigation: IBPB before exit to userspace':
+
+   Conditional IBPB mitigation is enabled. The kernel tracks when a CPU has
+   run a potentially malicious guest and issues an IBPB before the first
+   exit to userspace after VM-exit.
+
+ * 'Mitigation: IBPB on VMEXIT':
+
+   IBPB is issued on every VM-exit. This occurs when other mitigations like
+   RETBLEED or SRSO are already issuing IBPB on VM-exit.
+
+Mitigation control on the kernel command line
+----------------------------------------------
+
+The mitigation can be controlled via the ``vmscape=`` command line parameter:
+
+ * ``vmscape=off``:
+
+   Disable the VMSCAPE mitigation.
+
+ * ``vmscape=ibpb``:
+
+   Enable conditional IBPB mitigation (default when CONFIG_MITIGATION_VMSCAPE=y).
+
+ * ``vmscape=force``:
+
+   Force vulnerability detection and mitigation even on processors that are
+   not known to be affected.

 ===============================
 
 LOCALIO provides the nfs_uuid_t object and associated interfaces to
-allow proper network namespace (net-ns) and NFSD object refcounting:
-
-    We don't want to keep a long-term counted reference on each NFSD's
-    net-ns in the client because that prevents a server container from
-    completely shutting down.
-
-    So we avoid taking a reference at all and rely on the per-cpu
-    reference to the server (detailed below) being sufficient to keep
-    the net-ns active. This involves allowing the NFSD's net-ns exit
-    code to iterate all active clients and clear their ->net pointers
-    (which are needed to find the per-cpu-refcount for the nfsd_serv).
-
-    Details:
-
-     - Embed nfs_uuid_t in nfs_client. nfs_uuid_t provides a list_head
-       that can be used to find the client. It does add the 16-byte
-       uuid_t to nfs_client so it is bigger than needed (given that
-       uuid_t is only used during the initial NFS client and server
-       LOCALIO handshake to determine if they are local to each other).
-       If that is really a problem we can find a fix.
-
-     - When the nfs server confirms that the uuid_t is local, it moves
-       the nfs_uuid_t onto a per-net-ns list in NFSD's nfsd_net.
-
-     - When each server's net-ns is shutting down - in a "pre_exit"
-       handler, all these nfs_uuid_t have their ->net cleared. There is
-       an rcu_synchronize() call between pre_exit() handlers and exit()
-       handlers so any caller that sees nfs_uuid_t ->net as not NULL can
-       safely manage the per-cpu-refcount for nfsd_serv.
-
-     - The client's nfs_uuid_t is passed to nfsd_open_local_fh() so it
-       can safely dereference ->net in a private rcu_read_lock() section
-       to allow safe access to the associated nfsd_net and nfsd_serv.
-
-So LOCALIO required the introduction and use of NFSD's percpu_ref to
-interlock nfsd_destroy_serv() and nfsd_open_local_fh(), to ensure each
-nn->nfsd_serv is not destroyed while in use by nfsd_open_local_fh(), and
+allow proper network namespace (net-ns) and NFSD object refcounting.

+to interlock nfsd_shutdown_net() and nfsd_open_local_fh(), to ensure
+each net-ns is not destroyed while in use by nfsd_open_local_fh(), and
 warrants a more detailed explanation:
 
-    nfsd_open_local_fh() uses nfsd_serv_try_get() before opening its
+    nfsd_open_local_fh() uses nfsd_net_try_get() before opening its
     nfsd_file handle and then the caller (NFS client) must drop the

-    nfs_file_put_local() once it has completed its IO.

     This interlock working relies heavily on nfsd_open_local_fh() being
     afforded the ability to safely deal with the possibility that the
     NFSD's net-ns (and nfsd_net by association) may have been destroyed
-    by nfsd_destroy_serv() via nfsd_shutdown_net() -- which is only
-    possible given the nfs_uuid_t ->net pointer managemenet detailed
-    above.

+Durability and copy up
+----------------------
+
+The fsync(2) system call ensures that the data and metadata of a file
+are safely written to the backing storage, which is expected to
+guarantee the existence of the information post system crash.
+
+Without an fsync(2) call, there is no guarantee that the observed
+data after a system crash will be either the old or the new data, but
+in practice, the observed data after crash is often the old or new data
+or a mix of both.
+
+When an overlayfs file is modified for the first time, copy up will
+create a copy of the lower file and its parent directories in the upper
+layer.  Since the Linux filesystem API does not enforce any particular
+ordering on storing changes without explicit fsync(2) calls, in case
+of a system crash, the upper file could end up with no data at all
+(i.e. zeros), which would be an unusual outcome.  To avoid this
+experience, overlayfs calls fsync(2) on the upper file before completing
+data copy up with rename(2) or link(2) to make the copy up "atomic".
+
+By default, overlayfs does not explicitly call fsync(2) on copied up
+directories or on metadata-only copy up, so it provides no guarantee to
+persist the user's modification unless the user calls fsync(2).
+The fsync during copy up only guarantees that if a copy up is observed
+after a crash, the observed data is not zeroes or intermediate values
+from the copy up staging area.
+
+On traditional local filesystems with a single journal (e.g. ext4, xfs),
+fsync on a file also persists the parent directory changes, because they
+are usually modified in the same transaction, so metadata durability during
+data copy up effectively comes for free.  Overlayfs further limits risk by
+disallowing network filesystems as upper layer.
+
+Overlayfs can be tuned to prefer performance or durability when storing
+to the underlying upper layer.  This is controlled by the "fsync" mount
+option, which supports these values:
+
+- "auto": (default)
+    Call fsync(2) on upper file before completion of data copy up.
+    No explicit fsync(2) on directory or metadata-only copy up.
+- "strict":
+    Call fsync(2) on upper file and directories before completion of any
+    copy up.
+- "volatile": [*]
+    Prefer performance over durability (see `Volatile mount`_)

+Lints
+-----
+
+In Rust, it is possible to ``allow`` particular warnings (diagnostics, lints)
+locally, making the compiler ignore instances of a given warning within a given
+function, module, block, etc.
+
+It is similar to ``#pragma GCC diagnostic push`` + ``ignored`` + ``pop`` in C
+[#]_:
+
+.. code-block:: c
+
+	#pragma GCC diagnostic push
+	#pragma GCC diagnostic ignored "-Wunused-function"
+	static void f(void) {}
+	#pragma GCC diagnostic pop
+
+.. [#] In this particular case, the kernel's ``__{always,maybe}_unused``
+       attributes (C23's ``[[maybe_unused]]``) may be used; however, the example
+       is meant to reflect the equivalent lint in Rust discussed afterwards.
+
+But way less verbose:
+
+.. code-block:: rust
+
+	#[allow(dead_code)]
+	fn f() {}
+
+By that virtue, it makes it possible to comfortably enable more diagnostics by
+default (i.e. outside ``W=`` levels). In particular, those that may have some
+false positives but that are otherwise quite useful to keep enabled to catch
+potential mistakes.
+
+On top of that, Rust provides the ``expect`` attribute which takes this further.
+It makes the compiler warn if the warning was not produced. For instance, the
+following will ensure that, when ``f()`` is called somewhere, we will have to
+remove the attribute:
+
+.. code-block:: rust
+
+	#[expect(dead_code)]
+	fn f() {}
+
+If we do not, we get a warning from the compiler::
+
+	warning: this lint expectation is unfulfilled
+	 --> x.rs:3:10
+	  |
+	3 | #[expect(dead_code)]
+	  |          ^^^^^^^^^
+	  |
+	  = note: `#[warn(unfulfilled_lint_expectations)]` on by default
+
+This means that ``expect``\ s do not get forgotten when they are not needed, which
+may happen in several situations, e.g.:
+
+- Temporary attributes added while developing.
+
+- Improvements in lints in the compiler, Clippy or custom tools which may
+  remove a false positive.
+
+- When the lint is not needed anymore because it was expected that it would be
+  removed at some point, such as the ``dead_code`` example above.
+
+It also increases the visibility of the remaining ``allow``\ s and reduces the
+chance of misapplying one.
+
+Thus prefer ``expect`` over ``allow`` unless:
+
+- Conditional compilation triggers the warning in some cases but not others.
+
+  If there are only a few cases where the warning triggers (or does not
+  trigger) compared to the total number of cases, then one may consider using
+  a conditional ``expect`` (i.e. ``cfg_attr(..., expect(...))``). Otherwise,
+  it is likely simpler to just use ``allow``.
+
+- Inside macros, when the different invocations may create expanded code that
+  triggers the warning in some cases but not in others.
+
+- When code may trigger a warning for some architectures but not others, such
+  as an ``as`` cast to a C FFI type.
+
+As a more developed example, consider for instance this program:
+
+.. code-block:: rust
+
+	fn g() {}
+
+	fn main() {
+	    #[cfg(CONFIG_X)]
+	    g();
+	}
+
+Here, function ``g()`` is dead code if ``CONFIG_X`` is not set. Can we use
+``expect`` here?
+
+.. code-block:: rust
+
+	#[expect(dead_code)]
+	fn g() {}
+
+	fn main() {
+	    #[cfg(CONFIG_X)]
+	    g();
+	}
+
+This would emit a lint if ``CONFIG_X`` is set, since it is not dead code in that
+configuration. Therefore, in cases like this, we cannot use ``expect`` as-is.
+
+A simple possibility is using ``allow``:
+
+.. code-block:: rust
+
+	#[allow(dead_code)]
+	fn g() {}
+
+	fn main() {
+	    #[cfg(CONFIG_X)]
+	    g();
+	}
+
+An alternative would be using a conditional ``expect``:
+
+.. code-block:: rust
+
+	#[cfg_attr(not(CONFIG_X), expect(dead_code))]
+	fn g() {}
+
+	fn main() {
+	    #[cfg(CONFIG_X)]
+	    g();
+	}
+
+This would ensure that, if someone introduces another call to ``g()`` somewhere
+(e.g. unconditionally), then it would be spotted that it is not dead code
+anymore. However, the ``cfg_attr`` is more complex than a simple ``allow``.
+
+Therefore, it is likely that it is not worth using conditional ``expect``\ s when
+more than one or two configurations are involved or when the lint may be
+triggered due to non-local changes (such as ``dead_code``).

+Subsystem Trace Points: PCI
+===========================
+
+Overview
+========
+The PCI tracing system provides tracepoints to monitor critical hardware events
+that can impact system performance and reliability. These events normally show
+up here:
+
+	/sys/kernel/tracing/events/pci
+
+Cf. include/trace/events/pci.h for the events definitions.
+
+Available Tracepoints
+=====================
+
+pci_hp_event
+------------
+
+Monitors PCI hotplug events including card insertion/removal and link
+state changes.
+::
+
+    pci_hp_event  "%s slot:%s, event:%s\n"
+
+**Event Types**:
+
+* ``LINK_UP`` - PCIe link established
+* ``LINK_DOWN`` - PCIe link lost
+* ``CARD_PRESENT`` - Card detected in slot
+* ``CARD_NOT_PRESENT`` - Card removed from slot
+
+**Example Usage**::
+
+    # Enable the tracepoint
+    echo 1 > /sys/kernel/debug/tracing/events/pci/pci_hp_event/enable
+
+    # Monitor events (the following output is generated when a device is hotplugged)
+    cat /sys/kernel/debug/tracing/trace_pipe
+       irq/51-pciehp-88      [001] .....  1311.177459: pci_hp_event: 0000:00:02.0 slot:10, event:CARD_PRESENT
+
+       irq/51-pciehp-88      [001] .....  1311.177566: pci_hp_event: 0000:00:02.0 slot:10, event:LINK_UP
+
+pcie_link_event
+---------------
+
+Monitors PCIe link speed changes and provides detailed link status information.
+::
+
+    pcie_link_event  "%s type:%d, reason:%d, cur_bus_speed:%d, max_bus_speed:%d, width:%u, flit_mode:%u, status:%s\n"
+
+**Parameters**:
+
+* ``type`` - PCIe device type (4=Root Port, etc.)
+* ``reason`` - Reason for link change:
+
+  - ``0`` - Link retrain
+  - ``1`` - Bus enumeration
+  - ``2`` - Bandwidth notification enable
+  - ``3`` - Bandwidth notification IRQ
+  - ``4`` - Hotplug event
+
+
+**Example Usage**::
+
+    # Enable the tracepoint
+    echo 1 > /sys/kernel/debug/tracing/events/pci/pcie_link_event/enable
+
+    # Monitor events (the following output is generated when a device is hotplugged)
+    cat /sys/kernel/debug/tracing/trace_pipe
+       irq/51-pciehp-88      [001] .....   381.545386: pcie_link_event: 0000:00:02.0 type:4, reason:4, cur_bus_speed:20, max_bus_speed:23, width:1, flit_mode:0, status:DLLLA

+KVM_X86_QUIRK_STUFF_FEATURE_MSRS    By default, at vCPU creation, KVM sets the
+                                    vCPU's MSR_IA32_PERF_CAPABILITIES (0x345),
+                                    MSR_IA32_ARCH_CAPABILITIES (0x10a),
+                                    MSR_PLATFORM_INFO (0xce), and all VMX MSRs
+                                    (0x480..0x492) to the maximal capabilities
+                                    supported by KVM.  KVM also sets
+                                    MSR_IA32_UCODE_REV (0x8b) to an arbitrary
+                                    value (which is different for Intel vs.
+                                    AMD).  Lastly, when guest CPUID is set (by
+                                    userspace), KVM modifies select VMX MSR
+                                    fields to force consistency between guest
+                                    CPUID and L2's effective ISA.  When this
+                                    quirk is disabled, KVM zeroes the vCPU's MSR
+                                    values (with two exceptions, see below),
+                                    i.e. treats the feature MSRs like CPUID
+                                    leaves and gives userspace full control of
+                                    the vCPU model definition.  This quirk does
+                                    not affect VMX MSRs CR0/CR4_FIXED1 (0x487
+                                    and 0x489), as KVM does now allow them to
+                                    be set by userspace (KVM sets them based on
+                                    guest CPUID, for safety purposes).
+
+KVM_X86_QUIRK_IGNORE_GUEST_PAT      By default, on Intel platforms, KVM ignores
+                                    guest PAT and forces the effective memory
+                                    type to WB in EPT.  The quirk is not available
+                                    on Intel platforms which are incapable of
+                                    safely honoring guest PAT (i.e., without CPU
+                                    self-snoop, KVM always ignores guest PAT and
+                                    forces effective memory type to WB).  It is
+                                    also ignored on AMD platforms or, on Intel,
+                                    when a VM has non-coherent DMA devices
+                                    assigned; KVM always honors guest PAT in
+                                    such case. The quirk is needed to avoid
+                                    slowdowns on certain Intel Xeon platforms
+                                    (e.g. ICX, SPR) where self-snoop feature is
+                                    supported but UC is slow enough to cause
+                                    issues with some older guests that use
+                                    UC instead of WC to map the video RAM.
+                                    Userspace can disable the quirk to honor
+                                    guest PAT if it knows that there is no such
+                                    guest software, for example if it does not
+                                    expose a bochs graphics device (which is
+                                    known to have had a buggy driver).
+
+KVM_X86_QUIRK_VMCS12_ALLOW_FREEZE_IN_SMM   By default, KVM relaxes the consistency
+                                      check for GUEST_IA32_DEBUGCTL in vmcs12
+                                      to allow FREEZE_IN_SMM to be set.  When
+                                      this quirk is disabled, KVM requires this
+                                      bit to be cleared.  Note that the vmcs02
+                                      bit is still completely controlled by the
+                                      host, regardless of the quirk setting.

 	  Select the Default SATA Link Power Management (LPM) policy to use
 	  for chipsets / "South Bridges" supporting low-power modes. Such
 	  chipsets are ubiquitous across laptops, desktops and servers.
-
-	  The value set has the following meanings:
+	  Each policy combines power saving states and features:
+	   - Partial: The Phy logic is powered but is in a reduced power
+                      state. The exit latency from this state is no longer than
+                      10us).
+	   - Slumber: The Phy logic is powered but is in an even lower power
+                      state. The exit latency from this state is potentially
+		      longer, but no longer than 10ms.
+	   - DevSleep: The Phy logic may be powered down. The exit latency from
+	               this state is no longer than 20 ms, unless otherwise
+		       specified by DETO in the device Identify Device Data log.
+	   - HIPM: Host Initiated Power Management (host automatically
+		   transitions to partial and slumber).
+	   - DIPM: Device Initiated Power Management (device automatically
+		   transitions to partial and slumber).
+
+	  The possible values for the default SATA link power management
+	  policies are:
 		0 => Keep firmware settings
-		1 => Maximum performance
-		2 => Medium power
-		3 => Medium power with Device Initiated PM enabled
-		4 => Minimum power
-
-	  Note "Minimum power" is known to cause issues, including disk
-	  corruption, with some disks and should not be used.
+		1 => No power savings (maximum performance)
+		2 => HIPM (Partial)
+		3 => HIPM (Partial) and DIPM (Partial and Slumber)
+		4 => HIPM (Partial and DevSleep) and DIPM (Partial and Slumber)
+		5 => HIPM (Slumber and DevSleep) and DIPM (Partial and Slumber)
+
+	  Excluding the value 0, higher values represent policies with higher
+	  power savings.

- * C states, especially those with large exit latencies, can have a real
- * noticeable impact on workloads, which is not acceptable for most sysadmins,
- * and in addition, less performance has a power price of its own.
- *
- * As a general rule of thumb, menu assumes that the following heuristic
- * holds:
- *     The busier the system, the less impact of C states is acceptable
- *
- * This rule-of-thumb is implemented using a performance-multiplier:
- * If the exit latency times the performance multiplier is longer than
- * the predicted duration, the C state is not considered a candidate
- * for selection due to a too high performance impact. So the higher
- * this multiplier is, the longer we need to be idle to pick a deep C
- * state, and thus the less likely a busy CPU will hit such a deep
- * C state.
- *
- * Currently there is only one value determining the factor:
- * 10 points are added for each process that is waiting for IO on this CPU.
- * (This value was experimentally determined.)
- * Utilization is no longer a factor as it was shown that it never contributed
- * significantly to the performance multiplier in the first place.

  * DOC: teo-description
  *
  * The idea of this governor is based on the observation that on many systems
- * timer events are two or more orders of magnitude more frequent than any
- * other interrupts, so they are likely to be the most significant cause of CPU
- * wakeups from idle states.  Moreover, information about what happened in the
- * (relatively recent) past can be used to estimate whether or not the deepest
- * idle state with target residency within the (known) time till the closest
- * timer event, referred to as the sleep length, is likely to be suitable for
- * the upcoming CPU idle period and, if not, then which of the shallower idle
- * states to choose instead of it.
+ * timer interrupts are two or more orders of magnitude more frequent than any
+ * other interrupt types, so they are likely to dominate CPU wakeup patterns.
+ * Moreover, in principle, the time when the next timer event is going to occur
+ * can be determined at the idle state selection time, although doing that may
+ * be costly, so it can be regarded as the most reliable source of information
+ * for idle state selection.
  *
- * Of course, non-timer wakeup sources are more important in some use cases
- * which can be covered by taking a few most recent idle time intervals of the
- * CPU into account.  However, even in that context it is not necessary to
- * consider idle duration values greater than the sleep length, because the
- * closest timer will ultimately wake up the CPU anyway unless it is woken up
- * earlier.
+ * Of course, non-timer wakeup sources are more important in some use cases,
+ * but even then it is generally unnecessary to consider idle duration values
+ * greater than the time time till the next timer event, referred as the sleep
+ * length in what follows, because the closest timer will ultimately wake up the
+ * CPU anyway unless it is woken up earlier.
  *
- * Thus this governor estimates whether or not the prospective idle duration of
- * a CPU is likely to be significantly shorter than the sleep length and selects
- * an idle state for it accordingly.
+ * However, since obtaining the sleep length may be costly, the governor first
+ * checks if it can select a shallow idle state using wakeup pattern information
+ * from recent times, in which case it can do without knowing the sleep length
+ * at all.  For this purpose, it counts CPU wakeup events and looks for an idle
+ * state whose target residency has not exceeded the idle duration (measured
+ * after wakeup) in the majority of relevant recent cases.  If the target
+ * residency of that state is small enough, it may be used right away and the
+ * sleep length need not be determined.

+// MI200 : Clear SGPRs, VGPRs and LDS
+//   Uses two kernels launched separately:
+//   1. Clean VGPRs, LDS, and lower SGPRs
+//        Launches one workgroup per CU, each workgroup with 4x wave64 per SIMD in the CU
+//        Waves are "wave64" and have 128 VGPRs each, which uses all 512 VGPRs per SIMD
+//        Waves in the workgroup share the 64KB of LDS
+//        Each wave clears SGPRs 0 - 95. Because there are 4 waves/SIMD, this is physical SGPRs 0-383
+//        Each wave clears 128 VGPRs, so all 512 in the SIMD
+//        The first wave of the workgroup clears its 64KB of LDS
+//        The shader starts with "S_BARRIER" to ensure SPI has launched all waves of the workgroup
+//          before any wave in the workgroup could end.  Without this, it is possible not all SGPRs get cleared.
+//    2. Clean remaining SGPRs
+//        Launches a workgroup with 24 waves per workgroup, yielding 6 waves per SIMD in each CU
+//        Waves are allocating 96 SGPRs
+//          CP sets up SPI_RESOURCE_RESERVE_* registers to prevent these waves from allocating SGPRs 0-223.
+//          As such, these 6 waves per SIMD are allocated physical SGPRs 224-799
+//        Barriers do not work for >16 waves per workgroup, so we cannot start with S_BARRIER
+//          Instead, the shader starts with an S_SETHALT 1. Once all waves are launched CP will send unhalt command
+//        The shader then clears all SGPRs allocated to it, cleaning out physical SGPRs 224-799

+ * CRTC RGM and after the CRTC DGM.
+ *
+ * - The CRTC RGM block will be placed in the RGM LUT block if it is non-linear.
+ * - The CRTC DGM block will be placed in the DGM LUT block if it is non-linear.
+ * - The CRTC CTM will be placed in the gamut remap block if it is non-linear.
+ *
+ * The RGM block is typically more fully featured and accurate across
+ * all ASICs - DCE can't support a custom non-linear CRTC DGM.
+ *
+ * For supporting both plane level color management and CRTC level color
+ * management at once we have to either restrict the usage of CRTC properties
+ * or blend adjustments together.
+ *

+		 * before TXTT_0 check. After performing the workaround read of
+		 * TXSTMPH_0, we read TXSTMPL_0 again. Since consecutive

+	 * PWM: PWM output may not function correctly if the FIFO is empty when
+	 * a new SAR value is programmed
+	 *
+	 * Description:
+	 * When the PWM FIFO is empty, a new value programmed to the PWM Sample
+	 * register (PWM_PWMSAR) will be directly applied even if the current
+	 * timer period has not expired.
+	 *
+	 * If the new SAMPLE value programmed in the PWM_PWMSAR register is
+	 * less than the previous value, and the PWM counter register
+	 * (PWM_PWMCNR) that contains the current COUNT value is greater than
+	 * the new programmed SAMPLE value, the current period will not flip
+	 * the level. This may result in an output pulse with a duty cycle of
+	 * 100%.
+	 *
+	 * Consider a change from
+	 *     ________
+	 *    /        \______/
+	 *    ^      *        ^
+	 * to
+	 *     ____
+	 *    /    \__________/
+	 *    ^               ^
+	 * At the time marked by *, the new write value will be directly applied
+	 * to SAR even the current period is not over if FIFO is empty.
+	 *
+	 *     ________        ____________________
+	 *    /        \______/                    \__________/
+	 *    ^               ^      *        ^               ^
+	 *    |<-- old SAR -->|               |<-- new SAR -->|
+	 *
+	 * That is the output is active for a whole period.
+	 *
+	 * Workaround:
+	 * Check new SAR less than old SAR and current counter is in errata
+	 * windows, write extra old SAR into FIFO and new SAR will effect at
+	 * next period.
+	 *
+	 * Sometime period is quite long, such as over 1 second. If add old SAR
+	 * into FIFO unconditional, new SAR have to wait for next period. It
+	 * may be too long.
+	 *
+	 * Turn off the interrupt to ensure that not IRQ and schedule happen
+	 * during above operations. If any irq and schedule happen, counter
+	 * in PWM will be out of data and take wrong action.
+	 *
+	 * Add a safety margin 1.5us because it needs some time to complete
+	 * IO write.
+	 *
+	 * Use writel_relaxed() to minimize the interval between two writes to
+	 * the SAR register to increase the fastest PWM frequency supported.
+	 *
+	 * When the PWM period is longer than 2us(or <500kHz), this workaround
+	 * can solve this problem. No software workaround is available if PWM
+	 * period is shorter than IO write. Just try best to fill old data

+ * ftrace_regs - ftrace partial/optimal register set
+ *
+ * ftrace_regs represents a group of registers which is used at the
+ * function entry and exit. There are three types of registers.
+ *
+ * - Registers for passing the parameters to callee, including the stack
+ *   pointer. (e.g. rcx, rdx, rdi, rsi, r8, r9 and rsp on x86_64)
+ * - Registers for passing the return values to caller.
+ *   (e.g. rax and rdx on x86_64)
+ * - Registers for hooking the function call and return including the
+ *   frame pointer (the frame pointer is architecture/config dependent)
+ *   (e.g. rip, rbp and rsp for x86_64)
+ *
+ * Also, architecture dependent fields can be used for internal process.
+ * (e.g. orig_ax on x86_64)
+ *
+ * Basically, ftrace_regs stores the registers related to the context.
+ * On function entry, registers for function parameters and hooking the
+ * function call are stored, and on function exit, registers for function
+ * return value and frame pointers are stored.
+ *
+ * And also, it dpends on the context that which registers are restored
+ * from the ftrace_regs.
+ * On the function entry, those registers will be restored except for
+ * the stack pointer, so that user can change the function parameters
+ * and instruction pointer (e.g. live patching.)
+ * On the function exit, only registers which is used for return values
+ * are restored.
+ *
+ * NOTE: user *must not* access regs directly, only do it via APIs, because
+ * the member can be changed according to the architecture.
+ * This is why the structure is empty here, so that nothing accesses
+ * the ftrace_regs directly.

  * The softirq flavor of kcov_remote_*() functions is introduced as a temporary

- * Adding support is tracked in https://bugzilla.kernel.org/show_bug.cgi?id=210337.
- *
- * kcov_remote_start_usb_softirq():
- *
- * 1. Only collects coverage when called in the softirq context. This allows
- *    avoiding nested remote coverage collection sections in the task context.
- *    For example, USB/IP calls usb_hcd_giveback_urb() in the task context
- *    within an existing remote coverage collection section. Thus, KCOV should
- *    not attempt to start collecting coverage within the coverage collection
- *    section in __usb_hcd_giveback_urb() in this case.
- *
- * 2. Disables interrupts for the duration of the coverage collection section.
- *    This allows avoiding nested remote coverage collection sections in the
- *    softirq context (a softirq might occur during the execution of a work in
- *    the BH workqueue, which runs with in_serving_softirq() > 0).
- *    For example, usb_giveback_urb_bh() runs in the BH workqueue with
- *    interrupts enabled, so __usb_hcd_giveback_urb() might be interrupted in
- *    the middle of its remote coverage collection section, and the interrupt
- *    handler might invoke __usb_hcd_giveback_urb() again.
+ * work around for kcov's lack of nested remote coverage sections support in

  * of concurrent destructions.  Use a separate workqueue so that cgroup

+ * A cgroup destruction should enqueue work sequentially to:
+ * cgroup_offline_wq: use for css offline work
+ * cgroup_release_wq: use for css release work
+ * cgroup_free_wq: use for free work
+ *
+ * Rationale for using separate workqueues:
+ * The cgroup root free work may depend on completion of other css offline

+ * create a deadlock scenario where:
+ * - Free work waits for other css offline work to complete.
+ * - But other css offline work is queued after free work in the same queue.
+ *
+ * Example deadlock scenario with single workqueue (cgroup_destroy_wq):
+ * 1. umount net_prio
+ * 2. net_prio root destruction enqueues work to cgroup_destroy_wq (CPUx)
+ * 3. perf_event CSS A offline enqueues work to same cgroup_destroy_wq (CPUx)
+ * 4. net_prio cgroup_destroy_root->cgroup_lock_and_drain_offline.
+ * 5. net_prio root destruction blocks waiting for perf_event CSS A offline,

-	  result in dmesg getting spammed for a surprisingly long
-	  time.  This is really bad from a security perspective, and
-	  so architecture maintainers really need to do what they can

+/// The kernel's [`Box`] type -- a heap allocation for a single value of type `T`.
+///
+/// This is the kernel's version of the Rust stdlib's `Box`. There are several differences,
+/// for example no `noalias` attribute is emitted and partially moving out of a `Box` is not
+/// supported. There are also several API differences, e.g. `Box` always requires an [`Allocator`]
+/// implementation to be passed as generic, page [`Flags`] when allocating memory and all functions
+/// that may allocate memory are fallible.
+///
+/// `Box` works with any of the kernel's allocators, e.g. [`Kmalloc`], [`Vmalloc`] or [`KVmalloc`].
+/// There are aliases for `Box` with these allocators ([`KBox`], [`VBox`], [`KVBox`]).
+///
+/// When dropping a [`Box`], the value is also dropped and the heap memory is automatically freed.

+/// # Examples
+///
+/// ```

+/// A contiguous growable array type with contents allocated with the kernel's allocators (e.g.
+/// [`Kmalloc`], [`Vmalloc`] or [`KVmalloc`]), written `Vec<T, A>`.
+///
+/// For non-zero-sized values, a [`Vec`] will use the given allocator `A` for its allocation. For
+/// the most common allocators the type aliases [`KVec`], [`VVec`] and [`KVVec`] exist.
+///
+/// For zero-sized types the [`Vec`]'s pointer must be `dangling_mut::<T>`; no memory is allocated.
+///
+/// Generally, [`Vec`] consists of a pointer that represents the vector's backing buffer, the
+/// capacity of the vector (the number of elements that currently fit into the vector), its length
+/// (the number of elements that are currently stored in the vector) and the `Allocator` type used
+/// to allocate (and free) the backing buffer.
+///
+/// A [`Vec`] can be deconstructed into and (re-)constructed from its previously named raw parts
+/// and manually modified.
+///
+/// [`Vec`]'s backing buffer gets, if required, automatically increased (re-allocated) when elements
+/// are added to the vector.
+///
+/// # Invariants
+///
+/// - `self.ptr` is always properly aligned and either points to memory allocated with `A` or, for
+///   zero-sized types, is a dangling, well aligned pointer.
+///
+/// - `self.len` always represents the exact number of elements stored in the vector.
+///
+/// - `self.layout` represents the absolute number of elements that can be stored within the vector
+///   without re-allocation. For ZSTs `self.layout`'s capacity is zero. However, it is legal for the
+///   backing buffer to be larger than `layout`.
+///

+	 * So we need to interpret these here before sending them on.
+	 * By default, we assume single byte data, which is true
+	 * for system realtime (midi clock, start, stop and continue)
+	 * and active sensing, and handle the other (known) cases
+	 * separately.
+	 * In contrast to the standard, CME does not split sysex
+	 * into multiple 4-byte packets, but lumps everything together
+	 * into one. In addition, CME can string multiple messages
+	 * together in the same packet; pressing the Record button
+	 * on an UF6 sends a sysex message directly followed
+	 * by a song position pointer in the same packet.
+	 * For it to have any reasonable meaning, a sysex message
+	 * needs to be at least 3 bytes in length (0xf0, id, 0xf7),
+	 * corresponding to a packet size of 4 bytes, and the ones sent
+	 * by CME devices are 6 or 7 bytes, making the packet fragments
+	 * 7 or 8 bytes long (six or seven bytes plus preceding CN+CIN byte).
+	 * For the other types, the packet size is always 4 bytes,
+	 * as per the standard, with the data size being 3 for SPP
+	 * and 1 for the others.
+	 * Thus all packet fragments are at least 4 bytes long, so we can
+	 * skip anything that is shorter; this also conveniantly skips
+	 * packets with size 0, which CME devices continuously send when
+	 * they have nothing better to do.
+	 * Another quirk is that sometimes multiple messages are sent
+	 * in the same packet. This has been observed for midi clock
+	 * and active sensing i.e. 0x0f 0xf8 0x00 0x00 0x0f 0xfe 0x00 0x00,
+	 * but also multiple note ons/offs, and control change together
+	 * with MIDI clock. Similarly, some sysex messages are followed by
+	 * the song position pointer in the same packet, and occasionally

+# The test script sets up two network namespaces, source_ns and sink_ns,
+# connected via a veth link. Within source_ns, it continuously updates the
+# IPv6 routing table by flushing and inserting IPV6_NEXTHOP_ADDR_COUNT nexthop
+# IPs destined for SINK_LOOPBACK_IP_ADDR in sink_ns. This refresh occurs at a
+# rate of 1/ROUTING_TABLE_REFRESH_PERIOD per second for TEST_DURATION seconds.
+#
+# Simultaneously, multiple iperf3 clients within source_ns generate heavy
+# outgoing IPv6 traffic. Each client is assigned a unique port number starting
+# at 5000 and incrementing sequentially. Each client targets a unique iperf3
+# server running in sink_ns, connected to the SINK_LOOPBACK_IFACE interface
+# using the same port number.
+#
+# The number of iperf3 servers and clients is set to half of the total
+# available cores on each machine.
+#
+# NOTE: We have tested this script on machines with various CPU specifications,
+# ranging from lower to higher performance as listed below. The test script
+# effectively triggered a kernel soft lockup on machines running an unpatched
+# kernel in under a minute:
+#
+# - 1x Intel Xeon E-2278G 8-Core Processor @ 3.40GHz
+# - 1x Intel Xeon E-2378G Processor 8-Core @ 2.80GHz
+# - 1x AMD EPYC 7401P 24-Core Processor @ 2.00GHz
+# - 1x AMD EPYC 7402P 24-Core Processor @ 2.80GHz
+# - 2x Intel Xeon Gold 5120 14-Core Processor @ 2.20GHz
+# - 1x Ampere Altra Q80-30 80-Core Processor @ 3.00GHz
+# - 2x Intel Xeon Gold 5120 14-Core Processor @ 2.20GHz
+# - 2x Intel Xeon Silver 4214 24-Core Processor @ 2.20GHz
+# - 1x AMD EPYC 7502P 32-Core @ 2.50GHz
+# - 1x Intel Xeon Gold 6314U 32-Core Processor @ 2.30GHz
+# - 2x Intel Xeon Gold 6338 32-Core Processor @ 2.00GHz
+#
+# On less performant machines, you may need to increase the TEST_DURATION
+# parameter to enhance the likelihood of encountering a race condition leading
+# to a kernel soft lockup and avoid a false negative result.
+#
+# NOTE: The test may not produce the expected result in virtualized
+# environments (e.g., qemu) due to differences in timing and CPU handling,
+# which can affect the conditions needed to trigger a soft lockup.
