NAME

6       perf-sched - Tool to trace/measure scheduler properties (latencies)

SYNOPSIS

9       perf sched {record|latency|replay|trace}
10

DESCRIPTION

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