From 162f0befda3becc2cc9f44075fccc030e55baec1 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 11 Sep 2013 16:18:24 +0200 Subject: perf tools: Add time argument on COMM setting This way we can later delimit a lifecycle for the COMM and map a hist to a precise COMM:timeslice couple. PERF_RECORD_COMM and PERF_RECORD_FORK events that don't have PERF_SAMPLE_TIME samples can only send 0 value as a timestamp and thus should overwrite any previous COMM on a given thread because there is no sensible way to keep track of all the comms lifecycles in a thread without time informations.
