Subject: [PATCH 08/12] perf, tools, stat: Add extra output of counter values with -v
Date: Tue, 19 Jan 2016 18:27:40 -0800	[thread overview]
Message-ID: <1453256864-24192-9-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1453256864-24192-1-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.
