With drm-nightly kernel: commit c783b5011894af49992f2095cb2848b6cf8ebc57 Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Date: Wed Jan 20 10:12:32 2016 +0000 drm-intel-nightly: 2016y-01m-20d-10h-12m-03s UTC integration manifest and by disabling the DMC firmware from loading. I can't reproduce this issue. The issue is not reproducible either if DMC firmware is not loaded or DMC is loaded and I prevent the display from timing out. I.e. this does not actually block the OpenGL ES 3.1 CTS from passing on SKL. It should be duplicated to some DMC kernel bug. Created attachment 121169 [details]

dmesg from when the problem occur.
This issue is reproducible with dmc version 1.26 I ran the tests again with Mesa 11.2.0-devel git-5d87a7c but got conflicting results with our previous findings. This time we had random fails on "ES31-CTS.layout_binding.block_layout_binding_block_ComputeShader" with both display on and off. This makes me think that we just got lucky with the previous testing and this is unrelated to DMC. More investigation is needed. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

I am still gathering data on this issue, but so far: The number of failing tests on a full cts-runner run are equal to getting a new: "[66951.923100] [drm] stuck on render ring [66951.923838] [drm] GPU HANG: ecode 9:0:0x85dfffff, in cts-runner [14838], reason: Ring hung, action: reset [66951.926772] drm/i915: Resetting chip after gpu hang [66953.923521] [drm] RC6 on" in dmesg. The tests appear to fail on random configs. To check the result of the cts-runner I use the scripts/ So far after 4 runs I have only see these test fail on respective config: ----- run 1 ---- Verifying config-18-run-0.qpa FAIL: ES2-CTS.gtf.GL.operators.multiplicative_vert: Fail (Fail) Verifying config-25-run-0.qpa FAIL: ES31-CTS.layout_binding.block_layout_binding_block_ComputeShader: Fail (Fail) Verifying config-82-run-0.qpa FAIL: ES31-CTS.layout_binding.block_layout_binding_block_ComputeShader: Fail (Fail) Verifying config-89-run-0.qpa FAIL: ES2-CTS.gtf.GL.operators.multiplicative_vert: Fail (Fail) ----- run 2 ---- Verifying config-18-run-0.qpa FAIL: ES3-CTS.gtf.GL3Tests.npot_textures.npot_tex3d_render: Fail (Fail) Verifying config-25-run-0.qpa FAIL: ES3-CTS.gtf.GL3Tests.transform_feedback.transform_feedback_misc: Fail (Fail) ----- run 3 ---- Verifying config-18-run-1.qpa FAIL: ES3-CTS.gtf.GL3Tests.transform_feedback.transform_feedback_misc: Fail (Fail) Verifying config-25-run-0.qpa FAIL: ES31-CTS.layout_binding.block_layout_binding_block_ComputeShader: Fail (Fail) Verifying config-78-run-1.qpa FAIL: ES3-CTS.gtf.GL3Tests.transform_feedback.transform_feedback_misc: Fail (Fail) Verifying config-82-run-0.qpa FAIL: ES31-CTS.layout_binding.block_layout_binding_block_ComputeShader: Fail (Fail) ----- run 4 ---- Verifying config-82-run-0.qpa FAIL: ES2-CTS.gtf.GL.operators.multiplicative_vert: Fail (Fail) Verifying config-89-run-0.qpa FAIL: ES31-CTS.layout_binding.block_layout_binding_block_ComputeShader: Fail (Fail)
