[PATCH 13/16] drm/i915: Add i915_vma_unbind_unlocked, and take obj lock for i915_vma_unbind
Maarten Lankhorst
maarten.lankhorst at linux.intel.com
Wed Jul 28 13:23:20 UTC 2021
We want to remove more members of i915_vma, which requires the locking to be
held more often.
Start requiring gem object lock for i915_vma_unbind, as it's one of the
callers that may unpin pages.
Some special care is needed when evicting, because the last reference to the
object may be held by the VMA, so after __i915_vma_unbind, vma may be garbage,
and we need to cache vma->obj before unlocking.
