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-cursor-vs-nonblocking-modeset-atomic failed.
- Subtest 2x-long-cursor-vs-nonblocking-modeset-atomic failed.

Both are having the following kind of output:

commit 5b8a1ba36e9a99fd2674e9bfa1bb7f6f039c2c7c
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date:   Wed Jan 18 10:41:37 2017 +0100

    kms_cursor_legacy: Use cursor movement instead of hiding for 2x tests
    
    This forces the cursor fastpath to be used. While at it, add -atomic
    versions of the test to compare legacy pageflip vs atomic.
    
    The nonblocking modeset test is changed slightly, due to cdclk changes
    the page flip may be stalled so it's not useful to test it. Just test
    that a queued page flip + nonblocking modeset works as intended and
    there is no kernel spew.

commit 396601872ae2e8a8ee9c98569b04ea2078f0adb5
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date:   Tue Jan 17 17:07:52 2017 +0100

    kms_cursor_legacy: Make the 2x tests slightly more useful.
    
    Trying to run as many cursor updates during a nonblocking modeset won't
    work, because both crtc's might be involved in the modeset. Instead
    try to run as many cursor updates on both crtc's at the same time,
    while trying to queue page flips in between.
