Subject: [GIT PULL] Performance events changes for v6.10
Date: Mon, 13 May 2024 08:18:45 +0200 [thread overview]
Message-ID: <ZkGwxW0JArbudf/+@gmail.com> (raw)
Linus,
Please pull the latest perf/core Git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2024-05-13
# HEAD: 854dd99b5ddc9d90e31e5f112462a5994dd31810 perf/bpf: Mark perf_event_set_bpf_handler() and perf_event_free_bpf_handler() as inline too
Perf events changes for v6.10:
- Combine perf and BPF for fast evalution of HW breakpoint
conditions.
- Add LBR capture support outside of hardware events
- Trigger IO signals for watermark_wakeup
- Add RAPL support for Intel Arrow Lake and Lunar Lake
- Optimize frequency-throttling
- Miscellaneous cleanups & fixes.
Thanks,
Ingo
------------------>
Andrii Nakryiko (4):
perf/x86/amd: Ensure amd_pmu_core_disable_all() is always inlined
perf/x86/amd: Avoid taking branches before disabling LBR
perf/x86/amd: Support capturing LBR from software events
perf/x86/amd: Don't reject non-sampling events with configured LBR
Erick Archer (1):
perf/x86/rapl: Prefer struct_size() over open coded arithmetic
Ingo Molnar (2):
perf/bpf: Change the !CONFIG_BPF_SYSCALL stubs to static inlines
perf/bpf: Mark perf_event_set_bpf_handler() and perf_event_free_bpf_handler() as inline too
Kyle Huey (10):
perf/bpf: Reorder bpf_overflow_handler() ahead of __perf_event_overflow()
perf/bpf: Create bpf_overflow_handler() stub for !CONFIG_BPF_SYSCALL
perf/bpf: Remove #ifdef CONFIG_BPF_SYSCALL from struct perf_event members
perf/bpf: Call BPF handler directly, not through overflow machinery
perf/bpf: Remove unneeded uses_default_overflow_handler()
perf/bpf: Allow a BPF program to suppress all sample side effects
selftest/bpf: Test a perf BPF program that suppresses side effects
perf: Move perf_event_fasync() to perf_event.h
perf/ring_buffer: Trigger IO signals for watermark_wakeup
selftests/perf_events: Test FASYNC with watermark wakeups
Namhyung Kim (2):
perf/core: Optimize perf_adjust_freq_unthr_context()
perf/core: Reduce PMU access to adjust sample freq
Zhang Rui (2):
perf/x86/rapl: Add support for Intel Arrow Lake
perf/x86/rapl: Add support for Intel Lunar Lake
