perf test: Add sched latency and script shell tests2025-07-01T22:37:34ZIan Rogersirogers@google.com2025-06-28T01:23:02Zurn:sha1:0e22c5ca44e687981f79598e650d26faad101746
Add shell tests covering the `perf sched latency` and `perf sched
script` commands. The test creates 2 noploop processes on the same
forced CPU, it then checks that the process appears in the `perf
sched` output.
