For example, # perf record -e sched:sched_deadline_yield ~/yield-test Warning: [sched:sched_deadline_yield] unknown op '%' .... # perf script Warning: [sched:sched_deadline_yield] unknown op '%' test 1641 [006] 3364.109319: sched:sched_deadline_yield: \ [FAILED TO PARSE] now=3364109314595 \ deadline=3364139295135 runtime=19975597 This patch implements the '%' operation. With this patch, we see the correct output: # perf record -e sched:sched_deadline_yield ~/yield-test No Warning # perf script yield-test 4005 [001] 4623.650978: sched:sched_deadline_yield: \ now=4623.650974050 \ deadline=4623.680957364 remaining_runtime=19979611 Signed-off-by: Daniel Bristot de Oliveira <bristot@xxxxxxxxxx> Reviewed-by: Steven Rostedt <rostedt@xxxxxxxxxxx> Cc: Juri Lelli <juri.lelli@xxxxxxxxx> Cc: Peter Zijlstra <peterz@xxxxxxxxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: linux-rt-users <linux-rt-users@xxxxxxxxxxxxxxx> Link: http://lkml.kernel.org/r/5c96a395c56cea6d3d13d949051bdece86cc26e0.1456157869.git.bristot@xxxxxxxxxx Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> --- tools/lib/traceevent/event-parse.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/tools/lib/traceevent/event-parse.c b/tools/lib/traceevent/event-parse.c index c3bd294..575e751 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -1951,6 +1951,7 @@ process_op(struct event_format *event, struct print_arg *arg, char **tok) strcmp(token, "*") == 0 || strcmp(token, "^") == 0 || strcmp(token, "/") == 0 || + strcmp(token, "%") == 0 || strcmp(token, "<") == 0 || strcmp(token, ">") == 0 || strcmp(token, "<=") == 0 || @@ -3689,6 +3690,9 @@ eval_num_arg(void *data, int size, struct event_format *event, struct print_arg case '/': val = left / right; break; + case '%': + val = left % right; + break; case '*': val = left * right; break; -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
