13DESCRIPTION
14-----------
15There's four variants of perf sched:
16
17  'perf sched record <command>' to record the scheduling events
18  of an arbitrary workload.
19
20  'perf sched latency' to report the per task scheduling latencies
21  and other scheduling properties of the workload.
22
23  'perf sched trace' to see a detailed trace of the workload that
24  was recorded.
25
26  'perf sched replay' to simulate the workload that was recorded
27  via perf sched record. (this is done by starting up mockup threads
28  that mimic the workload based on the events in the trace. These
29  threads can then replay the timings (CPU runtime and sleep patterns)
30  of the workload as it occured when it was recorded - and can repeat
31  it a number of times, measuring its performance.)
