[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.

Signed-off-by: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Move time_quantum to symbol_conf. check for zero time quantum
