Subject: [PATCH 14/22] drm/i915: treat stolen as a region
Date: Fri, 27 Sep 2019 18:34:01 +0100 [thread overview]
Message-ID: <20190927173409.31175-15-matthew.auld@intel.com> (raw)
In-Reply-To: <20190927173409.31175-1-matthew.auld@intel.com>
Convert stolen memory over to a region object. Still leaves open the
question with what to do with pre-allocated objects...
