From ff676b193a401b23c84a79a7ec06559f3eaae917 Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Wed, 11 Nov 2009 00:04:01 +0900 Subject: [PATCH] perf bench: Improve sched-pipe.c with more comfortable output This patch improves sched-pipe.c with more comfortable output. Change points are comment style description and formatting numerical values and its units. Example: | % ./perf bench sched pipe | # Running sched/pipe benchmark... | # Extecuted 1000000 pipe operations between two tasks | | Total time:5.822 [sec] | | 5.822553 usecs/op | 171745 ops/sec Signed-off-by: Hitoshi Mitake Cc: Peter Zijlstra Cc: Paul Mackerras LKML-Reference: <1257865442-20252-3-git-send-email-mitake@dcl.info.waseda.ac.jp> Signed-off-by: Ingo Molnar --- tools/perf/bench/sched-pipe.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) diff --git a/tools/perf/bench/sched-pipe.c b/tools/perf/bench/sched-pipe.c index a9ac186714b..238185f9797 100644 --- a/tools/perf/bench/sched-pipe.c +++ b/tools/perf/bench/sched-pipe.c @@ -92,17 +92,18 @@ int bench_sched_pipe(int argc, const char **argv, switch (bench_format) { case BENCH_FORMAT_DEFAULT: - printf("(executing %d pipe operations between two tasks)\n\n", + printf("# Extecuted %d pipe operations between two tasks\n\n", loops); result_usec = diff.tv_sec * 1000000; result_usec += diff.tv_usec; - printf("\tTotal time:%lu.%03lu sec\n", - diff.tv_sec, diff.tv_usec / 1000); - printf("\t\t%lf usecs/op\n", + printf(" %14s: %lu.%03lu [sec]\n\n", "Total time", + diff.tv_sec, diff.tv_usec/1000); + + printf(" %14lf usecs/op\n", (double)result_usec / (double)loops); - printf("\t\t%d ops/sec\n", + printf(" %14d ops/sec\n", (int)((double)loops / ((double)result_usec / (double)1000000))); break;
