Subject: [Intel-gfx] [PATCH v4 2/4] drm/i915: Use the vma resource as argument for gtt binding / unbinding
When introducing asynchronous unbinding, the vma itself may no longer
be alive when the actual binding or unbinding takes place.
Can we take an extra reference counter of the vma to keep the vma alive, until the actual binding/unbinding takes place?
The point here is that that's not needed, and should be avoided. If the
vma is no longer alive, that means nobody uses it anymore, but the GPU
may still have work in the pipe that references the GPU virtual address.
