Subject: [PATCH 11/11] perf, tools, stat: Add extra output of counter values with -vv
Date: Wed, 27 Apr 2016 13:00:51 -0700
Message-ID: <1461787251-6702-12-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1461787251-6702-1-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.

v2: Make it depend on -vv, not -v
