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 , Lucas De Marchi , Michel Thierry Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" Display State Buffer (DSB) is hardware capability which allows driver to batch submit HW programming. As part of initial enablement common api created which currently used to program gamma lut proramming. Going forwad DSB support can be added for HDR and flip related operation. HSDES: 1209978241 BSpec: 32020 v1: Initial version. v2: Move intel_dsb files under display folder and fixed an issue.
