From 206cab651d07563d766c7f4cb73f858c5df3dec5 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Thu, 3 Mar 2016 15:57:37 -0800 Subject: perf stat: Add --metric-only support for -A Add metric only support for -A too. This requires a new print function that prints the metrics in the right order. v2: Fix manpage v3: Simplify nrcpus computation Signed-off-by: Andi Kleen Acked-by: Jiri Olsa Link: http://lkml.kernel.org/r/1457049458-28956-7-git-send-email-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/builtin-stat.c | 45 +++++++++++++++++++++++++++++++++++++-------- 1 file changed, 37 insertions(+), 8 deletions(-) (limited to 'tools/perf/builtin-stat.c') diff --git a/tools/perf/builtin-stat.c b/tools/perf/builtin-stat.c index 74508c9d0742..1f19f2f999c8 100644 --- a/tools/perf/builtin-stat.c +++ b/tools/perf/builtin-stat.c @@ -1250,10 +1250,40 @@ static void print_counter(struct perf_evsel *counter, char *prefix) } } +static void print_no_aggr_metric(char *prefix) +{ + int cpu; + int nrcpus = 0; + struct perf_evsel *counter; + u64 ena, run, val; + double uval; + + nrcpus = evsel_list->cpus->nr; + for (cpu = 0; cpu < nrcpus; cpu++) { + bool first = true; + + if (prefix) + fputs(prefix, stat_config.output); + evlist__for_each(evsel_list, counter) { + if (first) { + aggr_printout(counter, cpu, 0); + first = false; + } + val = perf_counts(counter->counts, cpu, 0)->val; + ena = perf_counts(counter->counts, cpu, 0)->ena; + run = perf_counts(counter->counts, cpu, 0)->run; + + uval = val * counter->scale; + printout(cpu, 0, counter, uval, prefix, run, ena, 1.0); + } + fputc('\n', stat_config.output); + } +} + static int aggr_header_lens[] = { [AGGR_CORE] = 18, [AGGR_SOCKET] = 12, - [AGGR_NONE] = 15, + [AGGR_NONE] = 6, [AGGR_THREAD] = 24, [AGGR_GLOBAL] = 0, }; @@ -1408,8 +1438,12 @@ static void print_counters(struct timespec *ts, int argc, const char **argv) fputc('\n', stat_config.output); break; case AGGR_NONE: - evlist__for_each(evsel_list, counter) - print_counter(counter, prefix); + if (metric_only) + print_no_aggr_metric(prefix); + else { + evlist__for_each(evsel_list, counter) + print_counter(counter, prefix); + } break; case AGGR_UNSET: default: @@ -2178,11 +2212,6 @@ int cmd_stat(int argc, const char **argv, const char *prefix __maybe_unused) goto out; } - if (metric_only && stat_config.aggr_mode == AGGR_NONE) { - fprintf(stderr, "--metric-only is not supported with -A\n"); - goto out; - } - if (metric_only && run_count > 1) { fprintf(stderr, "--metric-only is not supported with -r\n"); goto out; -- cgit v1.2.3
