Comment 2 Don Hiatt 2019-06-24 20:24:39 UTC
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.
Comment 3 Don Hiatt 2019-06-24 20:25:28 UTC
Assigning to myself to monitor and attempt to duplicate it.
Comment 4 Don Hiatt 2019-06-26 17:43:20 UTC
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.

Comment 7 Don Hiatt 2019-07-22 17:47:03 UTC
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).

Comment 8 Don Hiatt 2019-09-10 17:25:21 UTC
This has not occurred for 2 months now. Will continue to monitor.
Comment 9 Don Hiatt 2019-09-24 16:50:29 UTC
2 months + 2 weeks since this occurred. Will wait another couple of weeks and close if it doesn't happen again.
Comment 10 Don Hiatt 2019-10-04 16:39:20 UTC
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.
Comment 11 Don Hiatt 2019-10-15 17:40:02 UTC
Debug patch merged to IGT, if/when this occurs again we should have a little more insight into the issue.
