Linus,
Please pull the latest perf/core git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2021-02-17
# HEAD: 8bcfdd7cad3dffdd340f9a79098cbf331eb2cd53 Merge branch 'perf/kprobes' into perf/core, to pick up finished branch
The performance event updates for v5.12 are:
- Add CPU-PMU support for Intel Sapphire Rapids CPUs
- Extend the perf ABI with PERF_SAMPLE_WEIGHT_STRUCT, to offer two-parameter
sampling event feedback. Not used yet, but is intended for Golden Cove
CPU-PMU, which can provide both the instruction latency and the cache
latency information for memory profiling events.
- Remove experimental, default-disabled perfmon-v4 counter_freezing support
that could only be enabled via a boot option. The hardware is hopelessly
broken, we'd like to make sure nobody starts relying on this, as it would
only end in tears.
- Fix energy/power events on Intel SPR platforms
- Simplify the uprobes resume_execution() logic
- Misc smaller fixes.
Thanks,
Ingo
