perf test event_update: Fix memory leak of unit

2021-07-15T20:27:52Z

ASan reports a memory leak while running: # perf test "49: Synthesize attr update" Caused by a string being duplicated but never freed. This patch adds the missing free(). Note that evsel->unit is not deallocated together with evsel since it is supposed to be a constant string.

perf test event_update: Fix memory leak of evlist

2021-07-15T20:27:51Z

ASan reports a memory leak when running: # perf test "49: Synthesize attr update" Caused by evlist not being deleted. This patch adds the missing evlist__delete and removes the perf_cpu_map__put since it's already being deleted by evlist__delete.

perf evlist: Use the right prefix for alternative 'struct evlist' constructors

2020-11-30T18:04:05Z

perf_evlist__ is for 'struct perf_evlist' methods, in tools/lib/perf/, go on completing this split. Cc: Adrian Hunter Cc: Ian Rogers Cc: Jiri Olsa Cc: Namhyung Kim Signed-off-by: Arnaldo Carvalho de Melo

perf evsel: Rename perf_evselname() to evselname()

2020-05-05T19:35:30Z

As they are 'struct evsel' methods or related routines, not part of tools/lib/perf/, aka libperf, to whom the perf_ prefix belongs. Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Signed-off-by: Arnaldo Carvalho de Melo

libperf: Add perf_evlist__id_add() function

2019-09-25T12:51:48Z

Add the perf_evlist__id_add() function to libperf as an internal function. We already have the 'heads' member in 'struct perf_evlist'.

libperf: Add perf_evlist__first()/last() functions

2019-09-25T12:51:48Z

Add perf_evlist__first()/last() functions to libperf, as internal functions and rename perf's origins to evlist__first/last.

libperf: Add perf_evsel__alloc_id/perf_evsel__free_id functions

2019-09-25T12:51:48Z

Add perf_evsel__alloc_id()/perf_evsel__free_id() functions to libperf as internal functions. Move 'struct perf_sample_id' to internal/evsel.h header and change 'struct perf_sample_id::evsel' to 'struct perf_evsel' and the related code that touches it.

perf tools: Move event synthesizing routines to separate header

2019-09-20T12:19:22Z

Those are the only routines using the perf_event__handler_t typedef and are all related, so move to a separate header to reduce the header dependency tree, lots of places were getting event.h and even stdio.h, limits.h indirectly, so fix those as well.

perf env: Remove needless cpumap.h header

2019-09-20T12:19:21Z

Only a 'struct perf_cmp_map' forward allocation is necessary, fix the places that need the header but were getting it indirectly, by luck, from env.h.
