From c5659b74f052150791750234f92dcfb29d27efa5 Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Wed, 11 Nov 2009 00:04:02 +0900 Subject: perf bench: Improve sched-message.c with more comfortable output This patch improves sched-message.c with more comfortable output. Change points are comment style description and formatting numerical values and its units. Example: | % perf bench sched messaging | # Running sched/messaging benchmark... | # 20 sender and receiver processes per group | # 10 groups == 400 processes run | | Total time: 1.490 [sec] Signed-off-by: Hitoshi Mitake Cc: Peter Zijlstra Cc: Paul Mackerras LKML-Reference: <1257865442-20252-4-git-send-email-mitake@dcl.info.waseda.ac.jp> Signed-off-by: Ingo Molnar Cc: Peter Zijlstra Cc: Paul Mackerras --- tools/perf/bench/sched-messaging.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/tools/perf/bench/sched-messaging.c b/tools/perf/bench/sched-messaging.c index 2cc5edcca3d6..605a2a959aa8 100644 --- a/tools/perf/bench/sched-messaging.c +++ b/tools/perf/bench/sched-messaging.c @@ -314,12 +314,12 @@ int bench_sched_messaging(int argc, const char **argv, switch (bench_format) { case BENCH_FORMAT_DEFAULT: - printf("(%d sender and receiver %s per group)\n", + printf("# %d sender and receiver %s per group\n", num_fds, thread_mode ?
