perf/core improvements and fixes:
perf list:
Jiri Olsa:
- Display metric expressions for --details option
perf record:
Alexey Budankov:
- Implement --affinity=node|cpu option, leftover, the other patches
in this kit were already applied.
perf trace:
Arnaldo Carvalho de Melo:
- Fix segfaults due to not properly handling negative file descriptor syscall args.
- Fix segfault related to the 'waitid' 'options' prefix showing logic.
- Filter out 'gnome-terminal*' if it is a parent of 'perf trace', to reduce the
syscall feedback loop in system wide sessions.
BPF:
Song Liu:
- Silence "Couldn't synthesize bpf events" warning for EPERM.
Build system:
Arnaldo Carvalho de Melo:
- Fix the test-all.c feature detection fast path that was broken for
quite a while leading to longer build times.
Event parsing:
Jiri Olsa:
- Fix legacy events symbol separator parsing
cs-etm:
Mathieu Poirier:
- Fix some error path return errors and plug some memory leaks.
- Add proper header file for symbols
- Remove unused structure fields.
- Modularize auxtrace_buffer fetch, decoder and packet processing loop.
Vendor events:
Paul Clarke:
- Add assorted metrics for the Power8 and Power9 architectures.
perf report:
Thomas Richter:
- Add s390 diagnostic sampling descriptor size
