* ICL: igt@perf_pmu@rc6-runtime-pm-long - skip - Test requirement: igt_wait_for_pm_status(IGT_RUNTIME_PM_STATUS_SUSPENDED), SKIP
  - https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_284/fi-icl-u2/igt@perf_pmu@rc6-runtime-pm-long.html

The 'tests/perf_pmu.c' has three testings checking for RC6 residency reporting ("rc6," "rc6-runtime-pm," and "rc6-runtime-pm-long").

The test failing here is "rc6-runtime-pm-long" which puts the platform in the IGT_RUNTIME_PM_STATUS_SUSPENDED state and then sleeps "for a bit to see if once woken up estimated RC6 hasn't drifted to far in advance of real RC6."

In this case the test_rc6() IGT requirement of suspending is failing and the test is being skipped accordingly.

This occurred on fi-icl-u2 but hasn't been seen since drmtip_284 (1 month, 1 week old). Suggest we monitor this to see if it shows up again, if not close it.

Assigning to myself to monitor and attempt to duplicate it.

This SKIP occurred only one time in drmtip_284 and from drmtip_285 (1 month, 1 week old) until drmtip_315 (2 days, 16 hours old) has PASSED.

Looks like it was a one off failure but will continue to monitor.

This new SKIP started with CI_DRM_6470_resume and is now occurring on 're-icl-u' whereas it was originally reported on 'fi-icl-u2'. 

Prior to the failure in CI_DRM_6470_resume, this always passed CI_DRM_5891_re toCI_DRM_6404_resume. There has not been a another run since 6470_resume (1 week, 3 days old).

This has not occurred for 2 months now. Will continue to monitor.

2 months + 2 weeks since this occurred. Will wait another couple of weeks and close if it doesn't happen again.

I have a patch to IGT that will dump the pm runtime state if/when this occurs. This still looks to be a race in the test rather than an actual bug.

Debug patch merged to IGT, if/when this occurs again we should have a little more insight into the issue.
