Subject: [PATCH 09/10] drm/nouveau/ttm: handle ttm moves properly.
Date: Wed, 23 Sep 2020 13:04:53 +1000	[thread overview]
Message-ID: <20200923030454.362731-10-airlied@gmail.com> (raw)
In-Reply-To: <20200923030454.362731-1-airlied@gmail.com>

From: Dave Airlie <airlied@redhat.com>

The idea is to flip the core over to calling the driver always,
so add support for moves here.
