This is the i915 driver VM_BIND feature design RFC patch series along
with the required uapi definition and description of intended use cases.
v2: Reduce the scope to simple Mesa use case.
Remove all compute related uapi, vm_bind/unbind queue support and
only support a timeline out fence instead of an in/out timeline
fence array.
v3: Expand documentation on dma-resv usage, TLB flushing, execbuf3 and
VM_UNBIND. Add FENCE_VALID and TLB_FLUSH flags.
v4: Remove I915_GEM_VM_BIND_TLB_FLUSH flag and add additional
uapi documentation for vm_bind/unbind.
v5: Update TLB flushing documentation.
Add version support to stage implementation.
v6: Define and use drm_i915_gem_timeline_fence structure for
execbuf3 and vm_bind/unbind timeline fences.
v7: Rename I915_PARAM_HAS_VM_BIND to I915_PARAM_VM_BIND_VERSION.
Update documentation on async vm_bind/unbind and versioning.
Remove redundant vm_bind/unbind FENCE_VALID flag, execbuf3
batch_count field and I915_EXEC3_SECURE flag.
v8: Remove I915_GEM_VM_BIND_READONLY and minor documentation
updates.
