[PATCH 6/9] drm/amdgpu: track evicted page tables v2
Christian König
deathsimple at vodafone.de
Fri Aug 25 09:38:16 UTC 2017
From: Christian König <christian.koenig at amd.com>
Instead of validating all page tables when one was evicted,
track which one needs a validation.
v2: simplify amdgpu_vm_ready as well
