perf report: Add an indication of what time slices are used Add a time slices indication to the perf report header. For example, # perf report --stdio --time 10% # Total Lost Samples: 0 # # Samples: 9K of event 'cycles:ppp' (time slices: 10%) # Event count (approx.): 8951288803 Signed-off-by: Jin Yao <yao....@linux.intel.com> Suggested--by: Arnaldo Carvalho de Melo <a...@redhat.com> Tested-by: Arnaldo Carvalho de Melo <a...@redhat.com> Reviewed-by: Jiri Olsa <jo...@redhat.com> Cc: Alexander Shishkin <alexander.shish...@linux.intel.com> Cc: Andi Kleen <a...@linux.intel.com> Cc: Kan Liang <kan.li...@intel.com> Cc: Peter Zijlstra <pet...@infradead.org> Link: http://lkml.kernel.org/r/1515596433-24653-6-git-send-email-yao....@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <a...@redhat.com> --- tools/perf/builtin-report.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/tools/perf/builtin-report.c b/tools/perf/builtin-report.c index 7d4f0a5..4aaaa37 100644 --- a/tools/perf/builtin-report.c +++ b/tools/perf/builtin-report.c @@ -404,6 +404,9 @@ static size_t hists__fprintf_nr_sample_events(struct hists *hists, struct report if (evname != NULL) ret += fprintf(fp, " of event '%s'", evname); + if (rep->time_str) + ret += fprintf(fp, " (time slices: %s)", rep->time_str); + if (symbol_conf.show_ref_callgraph && strstr(evname, "call-graph=no")) { ret += fprintf(fp, ", show reference callgraph");
