Merge tag 'perf-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tipPull perf event updates from Ingo Molnar: - Improve Intel uncore PMU support: - Parse uncore 'discovery tables' - a new hardware capability enumeration method introduced on the latest Intel platforms. This table is in a well-defined PCI namespace location and is read via MMIO. It is organized in an rbtree. These uncore tables will allow the discovery of standard counter blocks, but fancier counters still need to be enumerated explicitly. - Add Alder Lake support - Improve IIO stacks to PMON mapping support on Skylake servers - Add Intel Alder Lake PMU support - which requires the introduction of 'hybrid' CPUs and PMUs. Alder Lake is a mix of Golden Cove ('big') and Gracemont ('small' - Atom derived) cores. The CPU-side feature set is entirely symmetrical - but on the PMU side there's core type dependent PMU functionality. - Reduce data loss with CPU level hardware tracing on Intel PT / AUX profiling, by fixing the AUX allocation watermark logic. - Improve ring buffer allocation on NUMA systems - Put 'struct perf_event' into their separate kmem_cache pool - Add support for synchronous signals for select perf events. The immediate motivation is to support low-overhead sampling-based race detection for user-space code. The feature consists of the following main changes: - Add thread-only event inheritance via perf_event_attr::inherit_thread, which limits inheritance of events to CLONE_THREAD. - Add the ability for events to not leak through exec(), via perf_event_attr::remove_on_exec. - Allow the generation of SIGTRAP via perf_event_attr::sigtrap, extend siginfo with an u64 ::si_perf, and add the breakpoint information to ::si_addr and ::si_perf if the event is PERF_TYPE_BREAKPOINT. The siginfo support is adequate for breakpoints right now - but the new field can be used to introduce support for other types of metadata passed over siginfo as well. - Misc fixes, cleanups and smaller updates.* tag 'perf-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) signal, perf: Add missing TRAP_PERF case in siginfo_layout() signal, perf: Fix siginfo_t by avoiding u64 on 32-bit architectures perf/x86: Allow for 8

f2c3c32f45002de19c6dec33f32fd259e82f2557 - selftests/perf_events: Add kselftest for process-wide sigtrap handling

Thu, 08 Apr 2021 12:36:02 +0200

selftests/perf_events: Add kselftest for process-wide sigtrap handlingAdd a kselftest for testing process-wide perf events with synchronousSIGTRAP on events (using breakpoints). In particular, we want to testthat changes to the event propagate to all children, and the SIGTRAPsare in fact synchronously sent to the thread where the event occurred.Note: The "signal_stress" test case is also added later in the series toperf tool's built-in tests. The test here is more elaborate in thatrespect, which on one hand avoids bloating the perf tool unnecessarily,but we also benefit from structured tests with TAP-compliant output thatthe kselftest framework provides.Signed-off-by: Marco Elver Signed-off-by: Peter Zijlstra (Intel) Link: https://lkml.kernel.org/r/20210408103605.1676875-8-elver@google.com List of files: /linux/tools/testing/selftests/perf_events/settings
