Linus Torvalds 6c4aa896eb Performance events changes for v6.14: ... - Seqlock optimizations that arose in a perf context and were merged into the perf tree: - seqlock: Add raw_seqcount_try_begin (Suren Baghdasaryan) - mm: Convert mm_lock_seq to a proper seqcount ((Suren Baghdasaryan) - mm: Introduce mmap_lock_speculate_{try_begin|retry} (Suren Baghdasaryan) - mm/gup: Use raw_seqcount_try_begin() (Peter Zijlstra) - Core perf enhancements: - Reduce 'struct page' footprint of perf by mapping pages in advance (Lorenzo Stoakes) - Save raw sample data conditionally based on sample type (Yabin Cui) - Reduce sampling overhead by checking sample_type in perf_sample_save_callchain() and perf_sample_save_brstack() (Yabin Cui) - Export perf_exclude_event() (Namhyung Kim) - Uprobes scalability enhancements: (Andrii Nakryiko) - Simplify find_active_uprobe_rcu() VMA checks - Add speculative lockless VMA-to-inode-to-uprobe resolution - Simplify session consumer tracking - Decouple return_instance list traversal and freeing - Ensure return_instance is detached from the list before freeing - Reuse return_instances between multiple uretprobes within task - Guard against kmemdup() failing in dup_return_instance() - AMD core PMU driver enhancements: - Relax privilege filter restriction on AMD IBS (Namhyung Kim) - AMD RAPL energy counters support: (Dhananjay Ugwekar) - Introduce topology_logical_core_id() (K Prateek Nayak) - Remove the unused get_rapl_pmu_cpumask() function - Remove the cpu_to_rapl_pmu() function - Rename rapl_pmu variables - Make rapl_model struct global - Add arguments to the init and cleanup functions - Modify the generic variable names to *_pkg* - Remove the global variable rapl_msrs - Move the cntr_mask to rapl_pmus struct - Add core energy counter support for AMD CPUs - Intel core PMU driver enhancements: - Support RDPMC 'metrics clear mode' feature (Kan Liang) - Clarify adaptive PEBS processing (Kan Liang) - Factor out functions for PEBS records processing (Kan Liang) - Simplify the PEBS records processing for adaptive PEBS (Kan Liang) - Intel uncore driver enhancements: (Kan Liang) - Convert buggy pmu->func_id use to pmu->registered - Support more units on Granite Rapids Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAmeOJdQRHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1i2yQ/+MXl7yfJOgdbwjBpgGGzH4burEO7ppak+ ktzz+YjpNgjODe/xMAJGjjblouuYArCnRolc1UPvPm6M7jSY76wi42Y6c4dRtFoB 2ReSrRqnreLOcrRS9nsTjvWRHfJHqJDVSd9TfHX6ILfzbaizCZOGYk558ZxAKRqu Lw7FOvLEe/Y3tg4z8dDg083jsasalKySP9wIPc0BkSqQTOfusd3KXju/Fux/9wkn hZcUgF4ds+0bH7xtO1/G9ILqGyeq97X1McIR9bAjln5Mxykclen4hSjRaWWHHo9O mzBKmd/blIATisfuuW+QLDQow3M1k3688cz7e9QOeWHHd/dJiMb9RLV90jdND/T/ uLINC5vNemzyWEfnNiYQ31LjhG3SeuDiKWzRp36MbQcCh6EBdRXWLBgtmxq1L/3o ZCaCdtFu5+6epycdyOVZEpWDnjdx4GmLXMZi5WJfZ7fZ/IFjNkjk4OdzI1iRQ+i3 Sbi75ep59ayTUhm5AB7gCJsP3R7EsZsiPHUenQdA2n9Sj6xE+IuhlS/QDQ9g5mdY Ijs0jHeVCGmhYoOD1xWnCZSzlnkEVU3zwfypAK+MC7pgtFMwDy5/Bu1USGxXXDy+ aKsrJRSgHbtZ1gwoHstqkV+DeCTfElCLYkvigzI5Nmyib5Zp4vkwy2ZLWQjaNjm7 mqRI7PugUkU= =c8XB -----END PGP SIGNATURE----- Merge tag 'perf-core-2025-01-20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull performance events updates from Ingo Molnar: "Seqlock optimizations that arose in a perf context and were merged into the perf tree: -
