Subject: [PATCH 11/11] perf, tools, stat: Add extra output of counter values with -v
Date: Mon, 4 Apr 2016 13:41:54 -0700 [thread overview]
Message-ID: <1459802514-31501-12-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1459802514-31501-1-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.
