Subject: [PATCH v3 10/22] drm/nouveau: Introduce GEM object functions
Date: Wed, 23 Sep 2020 12:21:47 +0200
Message-ID: <20200923102159.24084-11-tzimmermann@suse.de> (raw)
In-Reply-To: <20200923102159.24084-1-tzimmermann@suse.de>

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in nouveau.
