[PATCH v6 02/11] perf tools report: Parse time quantum
From: Andi Kleen
Date: Mon Mar 11 2019 - 10:45:20 EST
From: Andi Kleen <ak@xxxxxxxxxxxxxxx>
Many workloads change over time. perf report currently aggregates
the whole time range reported in perf.data.
This patch adds an option for a time quantum to quantisize the
perf.data over time.
This just adds the option, will be used in follow on patches
for a time sort key.
