Subject: [PATCH v3 11/11] perf, tools, stat: Update walltime_nsecs_stats in interval mode
Date: Thu, 31 Aug 2017 12:40:36 -0700	[thread overview]
Message-ID: <20170831194036.30146-12-andi@firstfloor.org> (raw)
In-Reply-To: <20170831194036.30146-1-andi@firstfloor.org>

From: Andi Kleen <ak@linux.intel.com>

Some metrics (like GFLOPs) need walltime_nsecs_stats for each interval.
Compute it for each interval instead of only at the end.

Pointed out by Jiri.
