X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: =?utf-8?q?Thomas_Hellstr=C3=B6m?= Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" From: Maarten Lankhorst This allows drivers to distinguish between different types of vma_node's. The readonly flag was unused and is thus removed. This is a temporary solution, until i915 is converted completely to use ttm for bo's.
