Subject: [Intel-gfx] [PATCH 01/46] drm/i915/guc: Allow flexible number of context ids
Date: Tue, 3 Aug 2021 15:28:58 -0700 [thread overview]
Message-ID: <20210803222943.27686-2-matthew.brost@intel.com> (raw)
In-Reply-To: <20210803222943.27686-1-matthew.brost@intel.com>
Number of available GuC contexts ids might be limited.
Stop referring in code to macro and use variable instead.
