Subject: [PATCH 08/11] perf, tools, stat: Add extra output of counter values with -v
Date: Fri, 15 Jan 2016 17:12:50 -0800 [thread overview]
Message-ID: <1452906773-7581-9-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1452906773-7581-1-git-send-email-andi@firstfloor.org>
From: Andi Kleen <ak@linux.intel.com>
Add debug output of raw counter values per CPU when
perf stat -v is specified, together with their cpu numbers.
This is very useful to debug problems with per core counters,
where we can normally only see aggregated values.
