Failure rate: 16% - igt@kms_cursor_legacy@(long-)?nonblocking-modeset-vs-cursor-atomic: This failure is happening only on fi-bsw-n3050, on drmtip runs. Failure rate: 10%, 85% of the time on the "long" subtest, and the rest on the non-long one. prime_vgem/basic-fence-flip timing loop was rewritten and should avoid this problem commit f43bb29c3e29143d8ad5fc70b82eccf5749d3958 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Apr 4 08:01:04 2019 +0100 prime_vgem: Downgrade the severity of a single missed vblank on flipping Not displaying the flip on the next vblank is bad, but not the end of the world -- so long as that is only a temporary glitch.

Last failure seen was 8 days ago, so we'll monitor that. However, I am lazy and I don't want to write another bug report for the other failures, so let's repurpose this bug for the other issue: https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_250/fi-bsw-n3050/igt@kms_cursor_legacy@long-nonblocking-modeset-vs-cursor-atomic.html Starting subtest: long-nonblocking-modeset-vs-cursor-atomic (kms_cursor_legacy:2734) CRITICAL: Test assertion failure function nonblocking_modeset_vs_cursor, file ../tests/kms_cursor_legacy.c:837: (kms_cursor_legacy:2734) CRITICAL: Failed assertion: 0 == poll(&pfd, 1, 0) (kms_cursor_legacy:2734) CRITICAL: Last errno: 25, Inappropriate ioctl for device (kms_cursor_legacy:2734) CRITICAL: error: 0 != 1 That assertion failure for kms_cursor_legacy.c:837 is that poll() after setting pipe to PIPE_NONE and committing it is still saying i915 wants us to read an event. I'll work on making kms_cursor_legacy provide clearer error messages on its failures. Can I move this to the display component? Looks like this bug was repurposed to a KMS bug, updating component accordingly. A CI Bug Log filter associated to this bug has been updated:
{- fi-bsw-n3050: igt@kms_cursor_legacy@(long-)?nonblocking-modeset-vs-cursor-atomic - fail - Failed assertion: 0 == poll(&pfd, 1, 0) -}
{+ fi-bsw-n3050 GLK: igt@kms_cursor_legacy@(long-)?nonblocking-modeset-vs-cursor-atomic - fail - Failed assertion: 0 == poll(&pfd, 1, 0) +}
No new failures caught with the new filter
