Based upon a hunk from a patch from Chris Wilson, but augmented to: - Process the batch in the full ppgtt vm so that self-relocations match again with userspace's expectations.. - Add a comment why plain pin for the global gtt binding is safe at that point. v2: Drop local bind_vm variable (Chris). v3: Explain why this works despite the lack of proper active tracking for the ggtt batch vma.
