perf util: Make util its own libraryMake the util directory into its own library. This is done to avoidcompiling code twice, once for the perf tool and once for the perfpython module. For convenience: arch/common.c scripts/perl/Perf-Trace-Util/Context.c scripts/python/Perf-Trace-Util/Context.care made part of this library.Signed-off-by: Ian Rogers Reviewed-by: James Clark Cc: Suzuki K Poulose Cc: Kees Cook Cc: Palmer Dabbelt Cc: Albert Ou Cc: Nick Terrell Cc: Gary Guo Cc: Alex Gaynor Cc: Boqun Feng Cc: Wedson Almeida Filho Cc: Ze Gao Cc: Alice Ryhl Cc: Andrei Vagin Cc: Yicong Yang Cc: Jonathan Cameron Cc: Guo Ren Cc: Miguel Ojeda Cc: Will Deacon Cc: Mike Leach Cc: Leo Yan Cc: Oliver Upton Cc: John Garry Cc: Benno Lossin Cc: Björn Roy Baron Cc: Andreas Hindborg Cc: Paul Walmsley Signed-off-by: Namhyung Kim Link: https://lore.kernel.org/r/20240625214117.953777-7-irogers@google.com List of files: /linux-6.15/tools/perf/util/hisi-ptt-decoder/Build

perf auxtrace arm64: Add support for parsing HiSilicon PCIe Trace packetAdd support for using 'perf report --dump-raw-trace' to parse PTT packet.Example usage:Output will contain raw PTT data and its textual representation, suchas (8DW format):0 0 0x5810 [0x30]: PERF_RECORD_AUXTRACE size: 0x400000 offset: 0ref: 0xa5d50c725 idx: 0 tid: -1 cpu: 0.. ... HISI PTT data: size 4194304 bytes. 00000000: 00 00 00 00 Prefix. 00000004: 08 20 00 60 Header DW0. 00000008: ff 02 00 01 Header DW1. 0000000c: 20 08 00 00 Header DW2. 00000010: 10 e7 44 ab Header DW3. 00000014: 2a a8 1e 01 Time. 00000020: 00 00 00 00 Prefix. 00000024: 01 00 00 60 Header DW0. 00000028: 0f 1e 00 01 Header DW1. 0000002c: 04 00 00 00 Header DW2. 00000030: 40 00 81 02 Header DW3. 00000034: ee 02 00 00 Time....This patch only add basic parsing support according to the definition ofthe PTT packet described in Documentation/trace/hisi-ptt.rst. And thefields of each packet can be further decoded following the PCIe Spec'sdefinition of TLP packet.Signed-off-by: Qi Liu Signed-off-by: Yicong Yang Cc: Alexander Shishkin Cc: Bjorn Helgaas Cc: Greg Kroah-Hartman Cc: Ingo Molnar Cc: James Clark Cc: John Garry Cc: Jonathan Cameron Cc: Leo Yan Cc: Lorenzo Pieralisi Cc: Mark Rutland Cc: Mathieu Poirier Cc: Mike Leach Cc: Peter Zijlstra Cc: Qi Liu Cc: Shameerali Kolothum Thodi Cc: Shaokun Zhang Cc: Suzuki Poulouse Cc: Will Deacon Cc: Zeng Prime Cc: linux-arm-kernel@lists.infradead.orgCc: linux-pci@vger.kernel.orgCc: linuxarm@huawei.comLink: https://lore.kernel.org/r/20220927081400.14364-4-yangyicong@huawei.comSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/util/hisi-ptt-decoder/Build
