From: "Chaos.Chen" <[email protected]> When rounding to microseconds, if the timestamp subsecond is between .999999500 and .999999999, it is rounded to .1000000, when it should instead increment the second counter due to the overflow.
For example, if the timestamp is 1234.999999501 instead of seeing: 1235.000000 we see 1234.1000000 Signed-off-by: Chaos.Chen <[email protected]> [ fixed incrementing "secs" instead of decrementing it ] Signed-off-by: Steven Rostedt <[email protected]> --- tools/lib/traceevent/event-parse.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/tools/lib/traceevent/event-parse.c b/tools/lib/traceevent/event-parse.c index c3bd294a63d1..a6f1ce779e05 100644 --- a/tools/lib/traceevent/event-parse.c +++ b/tools/lib/traceevent/event-parse.c @@ -5387,6 +5387,11 @@ void pevent_print_event(struct pevent *pevent, struct trace_seq *s, p = 9; } else { usecs = (nsecs + 500) / NSECS_PER_USEC; + /* To avoid usecs larger than 1 sec */ + if (usecs >= 1000000) { + usecs -= 1000000; + secs++; + } p = 6; } -- 2.6.4
