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 <mitake@xxxxxxxxxxxxxxxxxxxxx> Cc: Peter Zijlstra <a.p.zijlstra@xxxxxxxxx> Cc: Paul Mackerras <paulus@xxxxxxxxx> LKML-Reference: <1257808802-9420-4-git-send-email-mitake@xxxxxxxxxxxxxxxxxxxxx> Signed-off-by: Ingo Molnar <mingo@xxxxxxx> --- tools/perf/bench/sched-messaging.c | 18 +++++++++++------- 1 files changed, 11 insertions(+), 7 deletions(-) diff --git a/tools/perf/bench/sched-messaging.c b/tools/perf/bench/sched-messaging.c index 36b62c5..2cc5edc 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 ?
