From b90f1333ef08d2a497ae239798868b046f4e3a97 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Thu, 31 Aug 2017 12:40:36 -0700 Subject: [PATCH] perf stat: Update walltime_nsecs_stats in interval mode 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.
