[PATCH] perf report: Fix regression when decoding intelPT traces

From: Mathieu Poirier
Date: Wed Dec 13 2017 - 19:58:01 EST


Commit (93d10af26bb7 perf tools: Optimize sample parsing for ordered
events) breaks intelPT trace decoding by invariably returning an error if
the event type isn't a PERF_SAMPLE_TIME.

With this patch the timestamp is initialised and processing is allowed to
continue even if an error is returned by function
perf_evlist__parse_sample_timestamp().
