| |
Linus,
Please pull the latest perf/core git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2021-06-28
# HEAD: 012669c740e6e2afa8bdb95394d06676f933dd2d perf: Fix task context PMU for Hetero
Perf events updates for this cycle:
- Platform PMU driver updates:
- x86 Intel uncore driver updates for Skylake (SNR) and Icelake (ICX) servers - Fix RDPMC support - Fix [extended-]PEBS-via-PT support - Fix Sapphire Rapids event constraints - Fix :ppp support on Sapphire Rapids - Fix fixed counter sanity check on Alder Lake & X86_FEATURE_HYBRID_CPU - Other heterogenous-PMU fixes
- Kprobes:
- Remove the unused and misguided kprobe::fault_handler callbacks. - Warn about kprobes taking a page fault. - Fix the 'nmissed' stat counter.
- Misc cleanups and fixes.
