When introducing asynchronous unbinding, the vma itself may no longer be alive when the actual binding or unbinding takes place.
Update the gtt i915_vma_ops accordingly to take a struct i915_vma_resource instead of a struct i915_vma for the bind_vma() and unbind_vma() ops. Similarly change the insert_entries() op for struct i915_address_space.
Replace a couple of i915_vma_snapshot members with their newly introduced i915_vma_resource counterparts, since they have the same lifetime.
Also make sure to avoid changing the struct i915_vma_flags (in particular the bind flags) async. That should now only be done sync under the vm mutex.
v2: - Update the vma_res::bound_flags when binding to the aliased ggtt v6: - Remove I915_VMA_ALLOC_BIT (Matthew Auld) - Change some members of struct i915_vma_resource from unsigned long to u64 (Matthew Auld)
