Comment 2 Chris Wilson 2019-02-15 17:32:01 UTC
You see nothing; you definitely don't see a reocurrence of bug 108315.
Comment 3 Francesco Balestrieri 2019-02-18 06:54:01 UTC
So far this has failed once and then succeeded in several runs after that, including the latest one:

https://intel-gfx-ci.01.org/tree/drm-tip/fi-icl-u2.html

So it's not blocking BAT and probably shouldn't be highest priority.
Comment 4 Francesco Balestrieri 2019-03-01 08:32:06 UTC
Happened again: https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_5666/fi-icl-u2/igt@i915_selftest@live_requests.html

Still sporadic though.
Comment 5 Francesco Balestrieri 2019-03-22 08:56:50 UTC
Still happening. Lowering to medium.
Comment 6 Francesco Balestrieri 2019-03-22 08:57:10 UTC
I mean "still NOT happening" of course.
Comment 7 Chris Wilson 2019-04-11 10:02:09 UTC
More fingers crossed,

commit 632c7ad6f4509767fcbe76ac034747b4a30a13d9 (HEAD -> drm-intel-next-queued, drm-intel/for-linux-next, drm-intel/drm-intel-next-queued)

    drm/i915/icl: Switch to using 12 deep CSB status FIFO
    
    Now when we can support variable csb fifo sizes, disable legacy mode.
    By disabling legacy we hope to get better hw testing coverage by
    assuming everyone else have switched over.
    
    v2: rebase
