dmesg
Bug 75138 is triggered by the same test case and results in an OOM too, so holding off on this until that's resolved. commit ceabbba524fb43989875f66a6c06d7ce0410fe5c Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Mar 25 13:23:04 2014 +0000 drm/i915: Include bound and active pages in the count of shrinkable objects When the machine is under a lot of memory pressure and being stressed by multiple GPU threads, we quite often report fewer than shrinker->batch (i.e. SHRINK_BATCH) pages to be freed. This causes the shrink_control to skip calling into i915.ko to release pages, despite the GPU holding onto most of the physical pages in its active lists.
