This series enhances the HiSilicon PTT (PCIe Trace and Tuning) packet decoder in perf tool to provide detailed field-level parsing of TLP headers based on message type, and adds a versioning mechanism for backward compatibility both in hisi_ptt driver and perf tool. --- Changes in v2: - Split patch 01/10 and patch 02/10 from series v1 into independent patch series for backporting. - Use bitwise operations instead of C bitfields for cross-platform cases. - Add `pattern` parameter in hisi_ptt driver for layout compatibility. - Link to v1: https://lore.kernel.org/linux-pci/20260604075005.2219785-1-liusizhe5@huawei.com/ --- Sizhe Liu (8): perf hisi-ptt: Abstract trace data buf and offset perf hisi-ptt: Complete the field names for 4DW and 8DW packets perf hisi-ptt: Extract the raw data printing part perf hisi-ptt: Merge 4DW and 8DW HEAD0 printing perf hisi-ptt: Add parsing of supported message types perf hisi-ptt: Add field-level parsing for header DW2/DW3 hwtracing: hisi_ptt: Add pattern PMU config for trace format selection perf hisi-ptt: Pass pattern version to decoder for compatibility Documentation/trace/hisi-ptt.rst | 25 +- drivers/hwtracing/ptt/hisi_ptt.c | 25 +- drivers/hwtracing/ptt/hisi_ptt.h | 4 + tools/perf/arch/arm64/util/hisi-ptt.c | 18 ++ .../hisi-ptt-decoder/hisi-ptt-pkt-decoder.c | 291 ++++++++++++++---- .../hisi-ptt-decoder/hisi-ptt-pkt-decoder.h | 68 +++- tools/perf/util/hisi-ptt.c | 51 +-- tools/perf/util/hisi-ptt.h | 9 +- 8 files changed, 404 insertions(+), 87 deletions(-) base-commit: bec06676f4b2a4276b6277783eb91cd3cffd4b33 -- 2.33.0
