From 2c8e64514aa2ea414c8ada6c77405680267d0ab3 Mon Sep 17 00:00:00 2001 From: Zhengjun Xing Date: Fri, 22 Apr 2022 14:56:34 +0800 Subject: perf stat: Merge event counts from all hybrid PMUs For hybrid events, by default stat aggregates and reports the event counts per pmu. # ./perf stat -e cycles -a sleep 1 Performance counter stats for 'system wide': 14,066,877,268 cpu_core/cycles/ 6,814,443,147 cpu_atom/cycles/ 1.002760625 seconds time elapsed Sometimes, it's also useful to aggregate event counts from all PMUs. Create a new option '--hybrid-merge' to enable that behavior and report the counts without PMUs. # ./perf stat -e cycles -a --hybrid-merge sleep 1 Performance counter stats for 'system wide': 20,732,982,512 cycles 1.002776793 seconds time elapsed Reviewed-by: Kan Liang Signed-off-by: Xing Zhengjun Cc: Adrian Hunter Cc: Alexander Shishkin Cc: Andi Kleen Cc: Ian Rogers Cc: Ingo Molnar Cc: Jiri Olsa Cc: Peter Zijlstra Link: https://lore.kernel.org/r/20220422065635.767648-2-zhengjun.xing@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/builtin-stat.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'tools/perf/builtin-stat.c') diff --git a/tools/perf/builtin-stat.c b/tools/perf/builtin-stat.c index dea34c8990ae..5958bfd9a112 100644 --- a/tools/perf/builtin-stat.c +++ b/tools/perf/builtin-stat.c @@ -1258,6 +1258,8 @@ static struct option stat_options[] = { OPT_SET_UINT('A', "no-aggr", &stat_config.aggr_mode, "disable CPU count aggregation", AGGR_NONE), OPT_BOOLEAN(0, "no-merge", &stat_config.no_merge, "Do not merge identical named events"), + OPT_BOOLEAN(0, "hybrid-merge", &stat_config.hybrid_merge, + "Merge identical named hybrid events"), OPT_STRING('x', "field-separator", &stat_config.csv_sep, "separator", "print counts with custom separator"), OPT_CALLBACK('G', "cgroup", &evsel_list, "name", -- cgit v1.2.3
