Subject: [PATCH v5 01/18] drm/ttm: add gem base object
Date: Mon, 5 Aug 2019 14:42:53 +0200 [thread overview]
Message-ID: <20190805124310.3275-2-kraxel@redhat.com> (raw)
In-Reply-To: <20190805124310.3275-1-kraxel@redhat.com>
Add drm_gem_object struct to ttm_buffer_object, so ttm objects are a gdm
object superclass. Add a function to check whenever a given bo actually
uses the embedded drm_gem_object.
