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.
