Merge tag 'perf-core-for-mingo-5.1-20190321' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes from Arnaldo:
BPF:
Song Liu:
- Add support for annotating BPF programs, using the PERF_RECORD_BPF_EVENT
and PERF_RECORD_KSYMBOL recently added to the kernel and plugging
binutils's libopcodes disassembly of BPF programs with the existing
annotation interfaces in 'perf annotate', 'perf report' and 'perf top'
various output formats (--stdio, --stdio2, --tui).
perf list:
Andi Kleen:
- Filter metrics when using substring search.
perf record:
Andi Kleen:
- Allow to limit number of reported perf.data files
- Clarify help for --switch-output.
perf report:
Andi Kleen
- Indicate JITed code better.
- Show all sort keys in help output.
perf script:
Andi Kleen:
- Support relative time.
perf stat:
Andi Kleen:
- Improve scaling.
General:
Changbin Du:
- Fix some mostly error path memory and reference count leaks found
using gcc's ASan and UBSan.
Vendor events:
Mamatha Inamdar:
- Remove P8 HW events which are not supported.
