Merge tag 'perf-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull performance event updates from Ingo Molnar:
- 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.
