Description Martin Peres 2019-09-02 06:39:26 UTC
A lot of HSW regressed in piglit: https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_6816/pig-hsw-4770r/spec@ext_framebuffer_object@fbo-generatemipmap-formats.html

This looks like it was caused by:
dffa8feb3084 drm/i915/perf: Assert locking for i915_init_oa_perf_state()

We can rule that out simply by virtue hsw is not gen8.
Comment 3 Chris Wilson 2019-09-03 05:36:09 UTC
-7 should be SIGBUS, so I'd bet on an -ENOSPC from ggtt pinning. That too should be impossible...

    drm/i915: Refresh the errno to vmf_fault translations
    
    It's been a long time since we accidentally reported -EIO upon wedging,
    it can now only be generated by failure to swap in a page.

includes a test for the -ENOSPC on pin hypothesis.

Would you look at that!

Comment 9 Vanshidhar Konda 2019-11-06 19:23:48 UTC
This test was failing with this signature with 10-15 runs of the previous failure up until 1.5 weeks ago. This failure has not occurred in the past 78 runs. We should monitor this failure and close it if it doesn't reproduce in the next month.

Setting the priority to low as the bug has not been observed for a while.
