Comment 1 Daniel Vetter 2013-10-10 09:20:18 UTC

I've made a few changes recently to the kms_flip testcase. Is this a regression in i-g-t? If so can you please try to bisect it?

dmesg of case failed

I realized that this case (igt/kms_flip/bcs-flip-vs-modeset) was first added in nightly test On September 4th,but first failed on October 6th.
But I can't find a good commit on both drm-intel-fixes branch and drm-intel-next-queued branch.
If there is anything I can do to help,please let me know.

    drm/i915: Confine page flips to BCS on Valleyview

Comment 3 Daniel Vetter 2013-10-11 17:37:45 UTC

Like I've said it might be a regression in the i-g-t repository ... Can you please check there around the time this started to fail?

Comment 4 Daniel Vetter 2013-10-11 18:56:07 UTC

Ok, I've done the bisecting here quickly and fixed the bug in i-g-t:

commit a5d40a9bf27c2a41a981cb6fa168b1e68bfc0b3c
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Fri Oct 11 20:53:40 2013 +0200

    tests/kms_flip: fix igt_assert

But please check why your bisect tools didn't correctly pick this up.
