changes since v12: - add Reviewed-by tag for PATCH 1 from Steve - add Reviewed-by tag for PATCH 1-3 from Ilpo - add comments for why use string to define tracepoint per Steve - minor doc improvements from Ilpo - remove use pci_speed_string to fix PCI dependends which cause build error on sparc64 changes since v11: - rebase to Linux 6.18-rc1 (no functional changes) changes since v10: - explicitly include header file per Ilpo - add comma on any non-terminator entry per Ilpo - compile trace.o under CONFIG_TRACING per Ilpo changes since v9: - add a documentation about PCI tracepoints per Bjorn - create a dedicated drivers/pci/trace.c that always defines the PCI tracepoints per Steve - move tracepoint callite into __pcie_update_link_speed() per Lukas and Bjorn changes since v8: - rewrite commit log from Bjorn - move pci_hp_event to a common place (include/trace/events/pci.h) per Ilpo - rename hotplug event strings per Bjorn and Lukas - add PCIe link tracepoint per Bjorn, Lukas, and Ilpo changes since v7: - replace the TRACE_INCLUDE_PATH to avoid macro conflict per Steven - pick up Reviewed-by from Lukas Wunner Hotplug events are critical indicators for analyzing hardware health, and surprise link downs can significantly impact system performance and reliability. In addition, PCIe link speed degradation directly impacts system performance and often indicates hardware issues such as faulty devices, physical layer problems, or configuration errors. This patch set add PCI hotplug and PCIe link tracepoint to help analyze PCI hotplug events and PCIe link speed degradation.

Hi, Bjorn, Gentle ping. Do you have any further concerns about this patch set? Shuai
