Merge tag 'perf-core-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf events updates from Ingo Molnar: - 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 * tag 'perf-core-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits) perf/bpf: Mark perf_event_set_bpf_handler() and perf_event_free_bpf_handler() as inline too selftests/perf_events: Test FASYNC with watermark wakeups perf/ring_buffer: Trigger IO signals for watermark_wakeup perf: Move perf_event_fasync() to perf_event.h perf/bpf: Change the !CONFIG_BPF_SYSCALL stubs to static inlines selftest/bpf: Test a perf BPF program that suppresses side effects perf/bpf: Allow a BPF program to suppress all sample side effects perf/bpf: Remove unneeded uses_default_overflow_handler() perf/bpf: Call BPF handler directly, not through overflow machinery perf/bpf: Remove #ifdef CONFIG_BPF_SYSCALL from struct perf_event members perf/bpf: Create bpf_overflow_handler() stub for !CONFIG_BPF_SYSCALL perf/bpf: Reorder bpf_overflow_handler() ahead of __perf_event_overflow() perf/x86/rapl: Add support for Intel Lunar Lake perf/x86/rapl: Add support for Intel Arrow Lake perf/core: Reduce PMU access to adjust sample freq perf/core: Optimize perf_adjust_freq_unthr_context() perf/x86/amd: Don't reject non-sampling events with configured LBR perf/x86/amd: Support capturing LBR from software events perf/x86/amd: Avoid taking branches before disabling LBR perf/x86/amd: Ensure amd_pmu_core_disable_all() is always inlined ...
