2024-06-26	perf util: Make util its own library	Ian Rogers
	Make the util directory into its own library. This is done to avoid compiling code twice, once for the perf tool and once for the perf python module. For convenience: arch/common.c scripts/perl/Perf-Trace-Util/Context.c scripts/python/Perf-Trace-Util/Context.c are made part of this library.

2022-10-15	perf auxtrace arm64: Add support for parsing HiSilicon PCIe Trace packet	Qi Liu
	Add support for using 'perf report --dump-raw-trace' to parse PTT packet. Example usage: Output will contain raw PTT data and its textual representation, such as (8DW format): 0 0 0x5810 [0x30]: PERF_RECORD_AUXTRACE size: 0x400000 offset: 0 ref: 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 of the PTT packet described in Documentation/trace/hisi-ptt.rst. And the fields of each packet can be further decoded following the PCIe Spec's definition of TLP packet.
