From cced06c62a9db6bd6d77e3f0a57dbe47a26d881e Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Tue, 10 Nov 2009 08:20:01 +0900 Subject: perf bench: Modify bench/bench-messaging.c to adopt unified output formatting This patch modifies bench/bench-messaging.c to adopt unified output formatting: --format option. Usage example: % ./perf bench sched messaging # with no style specify (20 sender and receiver processes per group) (10 groups == 400 processes run) Total time:1.431 sec % ./perf bench --format=simple sched messaging # specified simple 1.431 Signed-off-by: Hitoshi Mitake Cc: Peter Zijlstra Cc: Paul Mackerras LKML-Reference: <1257808802-9420-4-git-send-email-mitake@dcl.info.waseda.ac.jp> Signed-off-by: Ingo Molnar --- tools/perf/bench/sched-messaging.c | 18 +++++++++++------- 1 file changed, 11 insertions(+), 7 deletions(-) (limited to 'tools/perf') diff --git a/tools/perf/bench/sched-messaging.c b/tools/perf/bench/sched-messaging.c index 36b62c549e28..2cc5edcca3d6 100644 --- a/tools/perf/bench/sched-messaging.c +++ b/tools/perf/bench/sched-messaging.c @@ -35,7 +35,6 @@ static int use_pipes = 0; static unsigned int loops = 100; static unsigned int thread_mode = 0; static unsigned int num_groups = 10; -static int simple = 0; struct sender_context { unsigned int num_fds; @@ -261,9 +260,6 @@ static const struct option options[] = { "Specify number of groups"), OPT_INTEGER('l', "loop", &loops, "Specify number of loops"), - OPT_BOOLEAN('s', "simple-output", &simple, - "Do simple output (this maybe useful for" - "processing by scripts or graph tools like gnuplot)"), OPT_END() }; @@ -316,9 +312,8 @@ int bench_sched_messaging(int argc, const char **argv, timersub(&stop, &start, &diff); - if (simple) - printf("%lu.%03lu\n", diff.tv_sec, diff.tv_usec/1000); - else { + switch (bench_format) { + case BENCH_FORMAT_DEFAULT: printf("(%d sender and receiver %s per group)\n", num_fds, thread_mode ?
