Subject: [GIT PULL] perf tooling changes for v5.8
From: Arnaldo Carvalho de Melo <acme@...hat.com>
Hi Linus,
These are additional changes to the perf tools, on top of what
Ingo has already submitted and you merged, please let me know if I made
any mistake,
Available from:
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git perf-tools-2020-06-02
# HEAD: 3e9b26dc2268cfbeef85bee095f883264c18425c Remove some duplicated includes
A summary of what is here:
- Further Intel PT call-trace fixes
- Improve SELinux docs and tool warnings
- Fix race at exit in 'perf record' using eventfd.
- Add missing build tests to the default set of 'make -C tools/perf build-test'
- Sync msr-index.h getting new AMD MSRs to decode and filter in 'perf trace'.
- Fix fallback to libaudit in 'perf trace' for arches not using per-arch *.tbl files.
- Fixes for 'perf ftrace'.
- Fixes and improvements for the 'perf stat' metrics.
- Use dummy event to get PERF_RECORD_{FORK,MMAP,etc} while synthesizing
those metadata events for pre-existing threads.
- Fix leaks detected using clang tooling.
- Improvements to PMU event metric testing.
- Report summary for 'perf stat' interval mode at the end, summing up
all the intervals.
- Improve pipe mode, i.e. this now works as expected, continuously
dumping samples:
# perf record -g -e raw_syscalls:sys_enter | perf --no-pager script
- Fixes for event grouping, detecting incompatible groups such as:
# perf stat -e '{cycles,power/energy-cores/}' -v
WARNING: group events cpu maps do not match, disabling group:
anon group { power/energy-cores/, cycles }
power/energy-cores/: 0
cycles: 0-7
- Fixes for 'perf probe': blacklist address checking, number of
kretprobe instances, etc.
- JIT processing improvements and fixes plus the addition of a 'perf
test' entry for the java demangler.
- Add support for synthesizing first/last level cache, TLB and remove
access events from HW tracing in the auxtrace code, first to use is
ARM SPE.
- Vendor events updates and fixes, including for POWER9 and Intel.
- Allow using ~/.perfconfig for removing the ',' separators in 'perf
stat' output.
- Opt-in support for libpfm4.
Best Regards,
- Arnaldo
