Getting a divide by 0 when events are processed from a file: perf trace -i perf.data -s ... dnsmasq (1684), 10 events, inf%, 0.000 msec
The problem is that the event count is not incremented as events are processed. With this patch: perf trace -i perf.data -s ... dnsmasq (1684), 10 events, 8.9%, 0.000 msec Signed-off-by: David Ahern <dsah...@gmail.com> --- tools/perf/builtin-trace.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/tools/perf/builtin-trace.c b/tools/perf/builtin-trace.c index 8f47eaae2f34..0203324fe585 100644 --- a/tools/perf/builtin-trace.c +++ b/tools/perf/builtin-trace.c @@ -1770,8 +1770,10 @@ static int trace__process_sample(struct perf_tool *tool, if (!trace->full_time && trace->base_time == 0) trace->base_time = sample->time; - if (handler) + if (handler) { + ++trace->nr_events; handler(trace, evsel, sample); + } return err; } -- 1.8.3.4 (Apple Git-47) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
