From d35d98eb1442f0780f5e7a09fa0258e0b3557602 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 16 Jun 2023 00:32:10 -0700 Subject: [PATCH] perf stat: Reset aggr stats for each run [ Upstream commit ed4090a22c123b9b33368741253edddc6ff8d18f ] When it runs multiple times with -r option, it missed to reset the aggregation counters and the values were added up. The aggregation count has the values to be printed in the end. It should reset the counters at the beginning of each run. But the current code does that only when -I/--interval-print option is given.
