Subject: [PATCH 35/42] perf record: Synthesize COMM event for a command line workload
Date: Thu, 29 Jan 2015 17:07:16 +0900	[thread overview]
Message-ID: <1422518843-25818-36-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1422518843-25818-1-git-send-email-namhyung@kernel.org>

When perf creates a new child to profile, the events are enabled on
exec().  And in this case, it doesn't synthesize any event for the
child since they'll be generated during exec().  But there's an window
between the enabling and the event generation.

It used to be overcome since samples are only in kernel (so we always
have the map) and the comm is overridden by a later COMM event.
However it won't work anymore since those samples will go to a missing
thread now but the COMM event will create a (current) thread.  This
leads to those early samples (like native_write_msr_safe) not having a
comm but pid (like ':15328').

So it needs to synthesize COMM event for the child explicitly before
enabling so that it can have a correct comm.  But at this time, the
comm will be "perf" since it's not exec-ed yet.
