Comment 2 Chris Wilson 2019-07-23 11:40:07 UTC
A nuisance, but we will hopefully see some improvement with more struct_mutex removal. This should be a temporary setback from not flushing as hard; although steps like https://patchwork.freedesktop.org/series/63943/ will help in correcting the shrink counters.
Comment 3 Andi 2019-07-27 11:26:00 UTC
This is another issue which is hard to reproduce.
I tried to reproduce it for one entire night, but couldn't manage to get the failure.

I would wait that Chris patch goes in and mark it as fixed.

    drm/i915: Hide unshrinkable context objects from the shrinker

Perhaps good enough for now. More to come later.
