Subject: drm/nouveau/gf116: remove copy1 engine
From: Ilia Mirkin <imirkin@xxxxxxxxxxxx>
commit 226d63a1addea8cbe8fc671978e62dc84927b046 upstream.
Indications are that no GF116's actually have a copy engine there, but
actually have the decompression engine. This engine can be made to do
copies, but that should be done separately.
Unclear why this didn't turn up on all GF116's, but perhaps the
non-mobile ones came with enough VRAM to not trigger ttm migrations in
test scenarios.
