Subject: [PATCH 10/10] perf, tools: Add support for MetricName JSON attribute
Date: Thu, 23 Feb 2017 16:10:21 -0800 [thread overview]
Message-ID: <20170224001021.6723-10-andi@firstfloor.org> (raw)
In-Reply-To: <20170224001021.6723-1-andi@firstfloor.org>
From: Andi Kleen <ak@linux.intel.com>
Add support for a new JSON event attribute to name MetricExpr for better output
in perf stat.
If the event has no MetricName it uses the normal event name instead to describe
the metric.
So far no names are added.
