[Intel-gfx] [PATCH 00/19] drm/i915: Short-term pinning and async eviction.

[Maarten Lankhorst]

Remove some parts of the i915_vma api, ensure obj->vma always exists,
and finally force the object lock to be taken when calling i915_vma_unbind
is called.

With this, locking is a lot cleaner, and we no longer need all the if (!obj->vma) checks.
We kill off the locking around i915_vma->set/get pages, and kill off the short-term
pinning/unpinning in execbuf.

After this, we go 1 step further, populate obj->moving where required, and add support
for async eviction/clearing.
