            Bug ID: 101571
           Summary: Vulkan tests fail on 4.12 drm-tip
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: mark.a.janes at intel.com
        QA Contact: intel-gfx-bugs at lists.freedesktop.org

I updated APL/BXT NUCs to drm-tip to test new GPU performance counter support:

Parent:     2a9433f12d1f Merge remote-tracking branch 'danvet/topic/e1000e-fix'
into drm-tip
Merged:     drm-tip
Containing: drm-tip
Follows:    v4.12-rc5 (1599)

drm-tip: 2017y-06m-19d-17h-57m-19s UTC integration manifest

I found that performance counters worked, but the system failed 90% of vulkan
CTS tests.

It may be easiest to observe this with the crucible test suite, which fails 90%
of tests with errors like:
crucible [master]: error  :
func.miptree.r8g8b8a8-unorm.aspect-color.view-3d.levels01.extent-32x32x32.upload-copy-from-buffer.download-copy-to-linear-image:
cru_image_compare_rect: diff found in row 0 of rect

Reverting to the stock 4.9 kernel fixed the regressions.

I used mesa c2f82fc1d3c for testing.

I didn't check other platforms, so it may be BXT specific.

GL/GLES tests did not regress.
