Reg. #1134945 - Pipers Way, Swindon SN3 1RJ Subject: [Intel-gfx] [PATCH v3 1/6] drm/i915/guc: distinguish HAS_GUC() from HAS_GUC_UCODE/HAS_GUC_SCHED X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" X-Spam-Status: No, score=-6.3 required=5.0 tests=BAYES_00, RCVD_IN_DNSWL_MED, RP_MATCHES_RCVD, UNPARSEABLE_RELAY autolearn=unavailable version=3.3.1 X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on mail.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP For now, anything with a GuC requires uCode loading, and then supports command submission once loaded. But these are logically distinct from simply "having a GuC", so we need a separate macro for the latter. Then, the test in intel_guc_reset() should depend only on whether the GuC exists, not whether we're trying to use it for submission.
