> Subject: [PATCH v11 0/4] add support for self monitoring
>
> 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
> advantages when application runs on isolated cores running dedicated tasks.
>
> 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.
>
> v11:
> - skip fast test in case init fails
> v10:
> - check permissions before using counters
> - do not use internal symbols in exported functions
> - address review comments
> v9:
> - fix 'maybe-uninitialized' warning reported by CI
> v8:
> - just rebase series
> v7:
> - use per-lcore event group instead of global table index by lcore-id
> - don't add pmu_autotest to fast tests because due to lack of suported on
> every arch
> 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
