X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Jani Nikula Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" Gamma lut programming can be programmed using DSB where bulk register programming can be done using indexed register write which takes number of data and the mmio offset to be written. v1: Initial version. v2: Directly call dsb-api at callsites.
