"user_cpus" can as well mean CPUs where we should only sample user level events, so perhaps bite the bullet and rename it to the longer 'evlist->user_requested_cpus' ? - Arnaldo > Signed-off-by: Ian Rogers > --- > tools/lib/perf/evlist.c | 28 ++++++++++++------------ > tools/lib/perf/include/internal/evlist.h | 4 +++- > tools/perf/arch/arm/util/cs-etm.c | 8 +++---- > tools/perf/arch/arm64/util/arm-spe.c | 2 +- > tools/perf/arch/x86/util/intel-bts.c | 2 +- > tools/perf/arch/x86/util/intel-pt.c | 4 ++-- > tools/perf/bench/evlist-open-close.c | 2 +- > tools/perf/builtin-ftrace.c | 2 +- > tools/perf/builtin-record.c | 6 ++--- > tools/perf/builtin-stat.c | 8 +++---- > tools/perf/builtin-top.c | 2 +- > tools/perf/util/auxtrace.c | 2 +- > tools/perf/util/bpf_ftrace.c | 4 ++-- > tools/perf/util/evlist.c | 14 ++++++------ > tools/perf/util/record.c | 6 ++--- > tools/perf/util/sideband_evlist.c | 2 +- > tools/perf/util/stat-display.c | 2 +- > tools/perf/util/synthetic-events.c | 2 +- > tools/perf/util/top.c | 7 +++--- > 19 files changed, 55 insertions(+), 52 deletions(-) > > diff --git a/tools/lib/perf/evlist.c b/tools/lib/perf/evlist.c > index 9a770bfdc804..e29dc229768a 100644 > --- a/tools/lib/perf/evlist.c > +++ b/tools/lib/perf/evlist.c > @@ -41,10 +41,10 @@ static void __perf_evlist__propagate_maps(struct perf_evlist *evlist, > */ > if (!evsel->own_cpus || evlist->has_user_cpus) { > perf_cpu_map__put(evsel->cpus); > - evsel->cpus = perf_cpu_map__get(evlist->cpus); > - } else if (!evsel->system_wide && perf_cpu_map__empty(evlist->cpus)) { > + evsel->cpus = perf_cpu_map__get(evlist->user_cpus); > + } else if (!evsel->system_wide && perf_cpu_map__empty(evlist->user_cpus)) { > perf_cpu_map__put(evsel->cpus); > - evsel->cpus = perf_cpu_map__get(evlist->cpus); > + evsel->cpus = perf_cpu_map__get(evlist->user_cpus); > } else if (evsel->cpus != evsel->own_cpus) { > perf_cpu_map__put(evsel->cpus); > evsel->cpus = perf_cpu_map__get(evsel->own_cpus); > @@ -123,10 +123,10 @@ static void perf_evlist__purge(struct perf_evlist *evlist) > > void perf_evlist__exit(struct perf_evlist *evlist) > { > - perf_cpu_map__put(evlist->cpus); > + perf_cpu_map__put(evlist->user_cpus); > perf_cpu_map__put(evlist->all_cpus); > perf_thread_map__put(evlist->threads); > - evlist->cpus = NULL; > + evlist->user_cpus = NULL; > evlist->all_cpus = NULL; > evlist->threads = NULL; > fdarray__exit(&evlist->pollfd); > @@ -155,9 +155,9 @@ void perf_evlist__set_maps(struct perf_evlist *evlist, > * original reference count of 1.
