PSR tests also seem to be failing because of this issue:

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_4527/fi-icl-u/igt@kms_psr@primary_mmap_gtt.html
Comment 1 Martin Peres 2018-07-23 13:01:09 UTC 
Bumping the priority because of the high number of issues hit in BAT.
Comment 2 James Ausmus 2018-08-09 23:11:16 UTC 
Looks like this was fixed with b9fcddab4afbac67660410009828eae83b6f3a36 "drm/i915/icl: implement icl_digital_port_connected()", which was merged July 25th (2 days after this bug was filed).

Looking at the fi-icl-u test results recently (https://intel-gfx-ci.01.org/tree/drm-tip/fi-icl-u.html), kms_busy@basic-flip-* has been passing (when it attempts to run at all), so it looks like we can close this down as Already Fixed. :)
Comment 3 Lakshmi 2018-08-23 14:48:47 UTC 
Last seen 3 weeks ago. Closing the issue.
Comment 4 Lakshmi 2018-08-28 06:34:48 UTC 
This issue didn't appear with drmtip only last two rounds. By then, it used to appear every round. So, to ensure that this defect is really closed, we can keep it open for at least next 8 rounds of drmtip execution. 

So reopening this issue. But this doesn't mean we need a fix for this issue.
Comment 5 James Ausmus 2018-09-27 23:56:58 UTC 
Can this be closed now?
Comment 6 James Ausmus 2018-09-27 23:58:50 UTC 
Looks like this issue has not been seen again for a long time, as we would expect after the missing code got merged. ;)

Closing again
