Subject[RFC 4/4] perf sched schedstat: Add support for report subcommand
Date
From: Swapnil Sapkal <swapnil.sapkal@amd.com>

`perf sched schedstat record` captures two sets of samples. For workload
profile, first set right before workload starts and second set after
workload finishes. For the systemwide profile, first set at the beginning
of profile and second set on receiving SIGINT signal.

Add `perf sched schedstat report` subcommand that will read both the set
of samples, get the diff and render a final report. Final report prints
scheduler stat at cpu granularity as well as sched domain granularity.

Usage example:

# perf sched schedstat record
# perf sched schedstat report
