This has certain adventages when application runs on\nisolated cores with nohz_full kernel parameter.\n\nEvents can be read directly using rte_pmu_read() or using dedicated\ntracepoint rte_eal_trace_pmu_read(). The latter will cause events to be\nstored inside CTF file.\n\nBy design, all enabled events are grouped together and the same group\nis attached to lcores that use self monitoring funtionality.\n\nEvents are enabled by names, which need to be read from standard\nlocation under sysfs i.e\n\n/sys/bus/event_source/devices/PMU/events\n\nwhere PMU is a core pmu i.e one measuring cpu events. As of today\nraw events are not supported.\n\nv2:\n- fix problems reported by test build infra\n\nTomasz Duszynski (4):\n eal: add generic support for reading PMU events\n eal/arm: support reading ARM PMU events in runtime\n eal/x86: support reading Intel PMU events in runtime\n eal: add PMU support to tracing library\n\n app/test/meson.build | 1 +\n app/test/test_pmu.c | 47 ++\n app/test/test_trace_perf.c | 4 +\n doc/guides/prog_guide/profile_app.rst | 13 +\n doc/guides/prog_guide/trace_lib.rst | 32 ++\n lib/eal/arm/include/meson.build | 1 +\n lib/eal/arm/include/rte_pmu_pmc.h | 39 ++\n lib/eal/arm/meson.build | 4 +\n lib/eal/arm/rte_pmu.c | 103 +++++\n lib/eal/common/eal_common_trace_points.c | 3 +\n lib/eal/common/meson.build | 3 +\n lib/eal/common/pmu_private.h | 41 ++\n lib/eal/common/rte_pmu.c | 519 +++++++++++++++++++++++\n lib/eal/include/meson.build | 1 +\n lib/eal/include/rte_eal_trace.h | 11 +\n lib/eal/include/rte_pmu.h | 207 +++++++++\n lib/eal/linux/eal.c | 4 +\n lib/eal/version.map | 6 +\n lib/eal/x86/include/meson.build | 1 +\n lib/eal/x86/include/rte_pmu_pmc.h | 33 ++\n 20 files changed, 1073 insertions(+)\n create mode 100644 app/test/test_pmu.c\n create mode 100644 lib/eal/arm/include/rte_pmu_pmc.h\n create mode 100644 lib/eal/arm/rte_pmu.c\n create mode 100644 lib/eal/common/pmu_private.h\n create mode 100644 lib/eal/common/rte_pmu.c\n create mode 100644 lib/eal/include/rte_pmu.h\n create mode 100644 lib/eal/x86/include/rte_pmu_pmc.h\n\n--\n2.25.1" }
