Message-Id: <1375490473-1503-5-git-send-email-andi@firstfloor.org> Date: Fri, 2 Aug 2013 17:41:12 -0700 From: Andi Kleen <andi@...stfloor.org> To: acme@...radead.org Cc: eranian@...gle.com, jolsa@...hat.com, linux-kernel@...r.kernel.org, Andi Kleen <ak@...ux.intel.com> Subject: [PATCH 4/5] perf, tools: flush output after each line in stat interval mode From: Andi Kleen <ak@...ux.intel.com> 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 <ak@...ux.intel.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) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
