Subject: [GIT PULL] perf updates for v4.20
Linus,
Please pull the latest perf-core-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-for-linus
# HEAD: dda93b45389f025fd3422d22cc31cc1ea6040305 Merge branch 'x86/cache' into perf/core, to pick up fixes
The main updates in this cycle were:
- Lots of perf tooling changes too voluminous to list (big perf trace
and perf stat improvements, lots of libtraceevent reorganization,
etc.), so I'll list the authors and refer to the changelog for
details:
Benjamin Peterson, Jérémie Galarneau, Kim Phillips, Peter Zijlstra,
Ravi Bangoria, Sangwon Hong, Sean V Kelley, Steven Rostedt,
Thomas Gleixner, Ding Xiang, Eduardo Habkost,
Thomas Richter, Andi Kleen, Sanskriti Sharma, Adrian Hunter,
Tzvetomir Stoyanov, Arnaldo Carvalho de Melo, Jiri Olsa.
... with the bulk of the changes written by Jiri Olsa, Tzvetomir
Stoyanov and Arnaldo Carvalho de Melo.
- Continued intel_rdt work with a focus on playing well with perf
events. This also imported some non-perf RDT work due to dependencies.
(Reinette Chatre)
- Implement counter freezing for Arch Perfmon v4 (Skylake and
newer). This allows to speed up the PMI handler by avoiding
unnecessary MSR writes and make it more accurate. (Andi Kleen)
- kprobes cleanups and simplification (Masami Hiramatsu)
- Intel Goldmont PMU updates (Kan Liang)
- ... plus misc other fixes and updates.
Thanks,
Ingo
