Subject: [PATCH 19/20] perf annotate: Add --percent-type option
Date: Sat, 4 Aug 2018 15:05:20 +0200 [thread overview]
Message-ID: <20180804130521.11408-20-jolsa@kernel.org> (raw)
In-Reply-To: <20180804130521.11408-1-jolsa@kernel.org>
Adding --percent-type option to set annotation percent type
from following choices:
global-period, local-period, global-hits, local-hits
Examples:
$ perf annotate --percent-type period-local --stdio | head -1
Percent | Source code ... es, percent: local period)
$ perf annotate --percent-type hits-local --stdio | head -1
Percent | Source code ... es, percent: local hits)
$ perf annotate --percent-type hits-global --stdio | head -1
Percent | Source code ... es, percent: global hits)
$ perf annotate --percent-type period-global --stdio | head -1
Percent | Source code ... es, percent: global period)
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).
