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 . . ...

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. Signed-off-by:

HiSilicon PCIe tune and trace device (PTT) could dynamically tune the PCIe link's events, and trace the TLP headers). This patch add support for PTT device in perf tool, so users could use 'perf record' to get TLP headers trace data. Reviewed-by:

Testcase stat+json_output.sh fails in powerpc: 86: perf stat JSON output linter : FAILED! The testcase "stat+json_output.sh" verifies perf stat JSON output. The test covers aggregation modes like per-socket, per-core, per-die, -A (no_aggr mode) along with few other tests. It counts expected fields for various commands. For example say -A (i.e, AGGR_NONE mode), expects 7 fields in the output having "CPU" as first field. Same way, for per-socket, it expects the first field in result to point to socket id. The testcases compares the result with expected count. The values for socket, die, core and cpu are fetched from topology directory: /sys/devices/system/cpu/cpu*/topology. For example, socket value is fetched from "physical_package_id" file of topology directory. (cpu__get_topology_int() in util/cpumap.c) If a platform fails to fetch the topology information, values will be set to -1. For example, incase of pSeries platform of powerpc, value for "physical_package_id" is restricted and not exposed. So, -1 will be assigned. Perf code has a checks for valid cpu id in "aggr_printout" (stat-display.c), which displays the fields. So, in cases where topology values not exposed, first field of the output displaying will be empty. This cause the testcase to fail, as it counts number of fields in the output. Incase of -A (AGGR_NONE mode,), testcase expects 7 fields in the output, becos of -1 value obtained from topology files for some, only 6 fields are printed. Hence a testcase failure reported due to mismatch in number of fields in the output. Patch here adds a sanity check in the testcase for topology. Check will help to skip the test if -1 value found.

If the kernel exposes a new perf_event_attr field in a format attr, perf will return an error stating the specified PMU can't be found. For example, a format attr with 'config3:0-63' causes an error as config3 is unknown to perf. This causes a compatibility issue between a newer kernel with older perf tool. Before this change with a kernel adding 'config3' I get: $ perf record -e arm_spe// -- true event syntax error: 'arm_spe//' \___ Cannot find PMU `arm_spe'. Missing kernel support? Run 'perf list' for a list of valid events Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] -e, --event <event> event selector. use 'perf list' to list available events After this change, I get: $ perf record -e arm_spe// -- true WARNING: 'arm_spe_0' format 'inv_event_filter' requires 'perf_event_attr::config3' which is not supported by this version of perf! [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.091 MB perf.data ] To support unknown configN formats, rework the YACC implementation to pass any config[0-9]+ format to perf_pmu__new_format() to handle with a warning.

Fix this by lowering the interval until a comfortable number of Perf instructions are generated. The test is still quick to run because only a small amount of trace is gathered.

Pull tracing fixes from Steven Rostedt: - Found that the synthetic events were using strlen/strscpy() on values that could have come from userspace, and that is bad. Consolidate the string logic of kprobe and eprobe and extend it to the synthetic events to safely process string addresses. - Clean up content of text dump in ftrace_bug() where the output does not make char reads into signed and sign extending the byte output. - Fix some kernel docs in the ring buffer code. * tag 'trace-v6.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix reading strings from synthetic events tracing: Add "(fault)" name injection to kernel probes tracing: Move duplicate code of trace_kprobe/eprobe.c into header ring-buffer: Fix kernel-doc ftrace: Fix char print issue in print_ip_ins()
