perf stat: Flush output after each line in interval mode When interval mode is outputting to a pipe, each measurement should be flushed individually, so that the reader sees it timely. With a terminal each line is automatically flushed by stdio, but that is disabled with non terminal output. Simply fflush output after each time interval Signed-off-by: Andi Kleen <a...@linux.intel.com> Reviewed-by: Jiri Olsa <jo...@redhat.com> Cc: Jiri Olsa <jo...@redhat.com> Cc: Stephane Eranian <eran...@google.com> Link: http://lkml.kernel.org/r/1375490473-1503-5-git-send-email-a...@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <a...@redhat.com> --- tools/perf/builtin-stat.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/tools/perf/builtin-stat.c b/tools/perf/builtin-stat.c index 2e637e4..f686d5f 100644 --- a/tools/perf/builtin-stat.c +++ b/tools/perf/builtin-stat.c @@ -416,6 +416,8 @@ static void print_interval(void) list_for_each_entry(counter, &evsel_list->entries, node) print_counter_aggr(counter, prefix); } + + fflush(output); } static void handle_initial_delay(void) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
