Subject: [PATCH 10/10] perf stat: Support inherit/no-inherit terms
Date: Thu, 24 Aug 2017 18:27:37 +0200 [thread overview]
Message-ID: <20170824162737.7813-11-jolsa@kernel.org> (raw)
In-Reply-To: <20170824162737.7813-1-jolsa@kernel.org>
Adding support to use 'inherit' and 'no-inherit' terms
in perf stat command, like:
To disable perf_event_attr::inherit (enabled by default):
$ perf stat -e cpu/cpu-cycles,no-inherit/u ...
Enable perf_event_attr::inherit (disabled by -i):
$ perf stat -i -e cpu/cpu-cycles,inherit/u ...
Signed-off-by: Jiri Olsa <jolsa@kernel.org>
