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

+
+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)
