From 106a94a0f8c207ef4113ce7e32f34a00b3b174e7 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 26 Jun 2015 11:29:19 +0200 Subject: [PATCH] perf stat: Introduce read_counters function Moving read counters logic into single read_counters function, which will be called for both interval and overall processing legs. The reason is to split reading and processing (following patches) counters code, so we could read counters from other sources (like perf.data) and process them in the same way as 'perf stat' command does.
