As a corollary, before doing the actual relocation through the GTT, we can make sure that we do have a GTT mapping through which to operate. Note that the key to make this work is to ditch the obj->map_and_fenceable unbind optimization - with full ppgtt it doesn't make a lot of sense any more anyway. v2: Revamp and resend to ease future patches. v3: Refresh patch rationale References: https://bugs.freedesktop.org/show_bug.cgi?id=81094 Signed-off-by: Chris Wilson Cc: Ben Widawsky Cc: Daniel Vetter [danvet: Explain why obj->map_and_fenceable is key and split out the secure batch fix.] Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
