This series adds self monitoring support i.e allows to configure and read performance measurement unit (PMU) counters in runtime without using perf utility. This has certain adventages when application runs on isolated cores with nohz_full kernel parameter. Events can be read directly using rte_pmu_read() or using dedicated tracepoint rte_eal_trace_pmu_read(). The latter will cause events to be stored inside CTF file. By design, all enabled events are grouped together and the same group is attached to lcores that use self monitoring funtionality. Events are enabled by names, which need to be read from standard location under sysfs i.e /sys/bus/event_source/devices/PMU/events where PMU is a core pmu i.e one measuring cpu events. As of today raw events are not supported. v6: - move codebase to the separate library - address review comments v5: - address review comments - fix sign extension while reading pmu on x86 - fix regex mentioned in doc - various minor changes/improvements here and there v4: - fix freeing mem detected by debug_autotest v3: - fix shared build v2: - fix problems reported by test build infra Tomasz Duszynski (4): lib: add generic support for reading PMU events pmu: support reading ARM PMU events in runtime pmu: support reading Intel x86_64 PMU events in runtime eal: add PMU support to tracing library MAINTAINERS | 5 + app/test/meson.build | 4 + app/test/test_pmu.c | 48 +++ app/test/test_trace_perf.c | 10 + doc/api/doxy-api-index.md | 3 +- doc/api/doxy-api.conf.in | 1 + doc/guides/prog_guide/profile_app.rst | 13 + doc/guides/prog_guide/trace_lib.rst | 32 ++ doc/guides/rel_notes/release_23_03.rst | 7 + lib/eal/common/eal_common_trace.c | 13 +- lib/eal/common/eal_common_trace_points.c | 5 + lib/eal/include/rte_eal_trace.h | 13 + lib/eal/meson.build | 3 + lib/eal/version.map | 3 + lib/meson.build | 1 + lib/pmu/meson.build | 21 + lib/pmu/pmu_arm64.c | 94 +++++ lib/pmu/pmu_private.h | 29 ++ lib/pmu/rte_pmu.c | 497 +++++++++++++++++++++++ lib/pmu/rte_pmu.h | 226 +++++++++++ lib/pmu/rte_pmu_pmc_arm64.h | 30 ++ lib/pmu/rte_pmu_pmc_x86_64.h | 24 ++ lib/pmu/version.map | 20 + 23 files changed, 1100 insertions(+), 2 deletions(-) create mode 100644 app/test/test_pmu.c create mode 100644 lib/pmu/meson.build create mode 100644 lib/pmu/pmu_arm64.c create mode 100644 lib/pmu/pmu_private.h create mode 100644 lib/pmu/rte_pmu.c create mode 100644 lib/pmu/rte_pmu.h create mode 100644 lib/pmu/rte_pmu_pmc_arm64.h create mode 100644 lib/pmu/rte_pmu_pmc_x86_64.h create mode 100644 lib/pmu/version.map -- 2.34.1
