Subject: perf: Add duration_time to perf stat
Date: Tue, 26 Mar 2019 15:18:19 -0700 [thread overview]
Message-ID: <20190326221823.11518-1-andi@firstfloor.org> (raw)
Currently it's not possible to get the wall clock time of a measurement
in CSV mode output, it's only in the non CSV perf stat output.
Often this is needed to normalize event counts to time.
Add a new duration_time event that can be specified and reports
the wall clock time in ns.
