[tag] [reply] [−] Description Jari Tahvanainen 2017-01-20 08:55:56 UTC
With nuclear page flip enabled (i915.nuclear_pageflip=1) and two screens
attached on SKL one has failure on kms_cursor_legacy subcases:
- Subtest 2x-long-nonblocking-modeset-vs-cursor-atomic failed.
- Subtest 2x-nonblocking-modeset-vs-cursor-atomic failed.

Both are having the following kind of output:
