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. v4: - fix freeing mem detected by debug_autotest v3: - fix shared build v2: - fix problems reported by test build infra Tomasz Duszynski (4): eal: add generic support for reading PMU events eal/arm: support reading ARM PMU events in runtime eal/x86: support reading Intel PMU events in runtime eal: add PMU support to tracing library app/test/meson.build | 1 + app/test/test_pmu.c | 47 ++ app/test/test_trace_perf.c | 4 + doc/guides/prog_guide/profile_app.rst | 13 + doc/guides/prog_guide/trace_lib.rst | 32 ++ lib/eal/arm/include/meson.build | 1 + lib/eal/arm/include/rte_pmu_pmc.h | 39 ++ lib/eal/arm/meson.build | 4 + lib/eal/arm/rte_pmu.c | 104 +++++ lib/eal/common/eal_common_trace_points.c | 3 + lib/eal/common/meson.build | 3 + lib/eal/common/pmu_private.h | 41 ++ lib/eal/common/rte_pmu.c | 519 +++++++++++++++++++++++ lib/eal/include/meson.build | 1 + lib/eal/include/rte_eal_trace.h | 11 + lib/eal/include/rte_pmu.h | 207 +++++++++ lib/eal/linux/eal.c | 4 + lib/eal/version.map | 7 + lib/eal/x86/include/meson.build | 1 + lib/eal/x86/include/rte_pmu_pmc.h | 33 ++ 20 files changed, 1075 insertions(+) create mode 100644 app/test/test_pmu.c create mode 100644 lib/eal/arm/include/rte_pmu_pmc.h create mode 100644 lib/eal/arm/rte_pmu.c create mode 100644 lib/eal/common/pmu_private.h create mode 100644 lib/eal/common/rte_pmu.c create mode 100644 lib/eal/include/rte_pmu.h create mode 100644 lib/eal/x86/include/rte_pmu_pmc.h -- 2.25.1
