- '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.
