Subject: [PATCH 20/20] perf report: Add --percent-type option
Date: Sat, 4 Aug 2018 15:05:21 +0200 [thread overview]
Message-ID: <20180804130521.11408-21-jolsa@kernel.org> (raw)
In-Reply-To: <20180804130521.11408-1-jolsa@kernel.org>
Set annotation percent type from following choices:
global-period, local-period, global-hits, local-hits
With following report option setup the percent type will be
passed to annotation browser:
$ perf report --percent-type period-local
The local/global keywords set if the percentage is computed
in the scope of the function (local) or the whole data (global).
The period/hits keywords set the base the percentage is computed
on - the samples period or the number of samples (hits).
