Merge tag 'perf-tools-fixes-for-v6.0-2022-08-13' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull more perf tool updates from Arnaldo Carvalho de Melo: - 'perf c2c' now supports ARM64, adjust its output to cope with differences with what is in x86_64. Now go find false sharing on ARM64 (at least Neoverse) as well! - Refactor the JSON processing, making the output more compact and thus reducing the size of the resulting perf binary - Improvements for 'perf offcpu' profiling, including tracking child processes - Update Intel JSON metrics and events files for broadwellde, broadwellx, cascadelakex, haswellx, icelakex, ivytown, jaketown, knightslanding, sapphirerapids, skylakex and snowridgex - Add 'perf stat' JSON output and a 'perf test' entry for it - Ignore memfd and anonymous mmap events if jitdump present - Refactor 'perf test' shell tests allowing subdirs - Fix an error handling path in 'parse_perf_probe_command()' - Fixes for the guest Intel PT tracing patchkit in the 1st batch of this merge window - Print debuginfod queries if -v option is used, to explain delays in processing when debuginfo servers are enabled to fetch DSOs with richer symbol tables - Improve error message for 'perf record -p not_existing_pid' - Fix openssl and libbpf feature detection - Add PMU pai_crypto event description for IBM z16 on 'perf list' - Fix typos and duplicated words on comments in various places * tag 'perf-tools-fixes-for-v6.0-2022-08-13' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (81 commits) perf test: Refactor shell tests allowing subdirs perf vendor events: Update events for snowridgex perf vendor events: Update events and metrics for skylakex perf vendor events: Update metrics for sapphirerapids perf vendor events: Update events for knightslanding perf vendor events: Update metrics for jaketown perf vendor events: Update metrics for ivytown perf vendor events: Update events and metrics for icelakex perf vendor events: Update events and metrics for haswellx perf vendor events: Update events and metrics for cascadelakex perf vendor events: Update events and metrics for broadwellx perf vendor events: Update metrics for broadwellde perf jevents: Fold strings optimization perf jevents: Compress the pmu_events_table perf metrics: Copy entire pmu_event in find metric perf pmu-events: Hide the pmu_events perf pmu-events: Don't assume pmu_event is an array perf pmu-events: Move test events/metrics to JSON perf test: Use full metric resolution perf pmu-events: Hide pmu_events_map ...
