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: , Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" X-Virus-Scanned: ClamAV using ClamSMTP In the i915 driver, there is a function, intel_guc_init_params(), which initializes the GuC parameter block which is passed into the GuC. There is parameter GUC_CTL_DEVICE_INFO with values GfxGtType and GfxCoreFamily unused by GuC. This patch remove GUC_CTL_DEVICE_INFO with GfxGtType and GfxCoreFamily parameters and also unnecessary functions get_gt_type() and get_core_family().
