Subject: [PATCH 38/51] drm/i915/guc: Hook GuC scheduling policies up
Date: Fri, 16 Jul 2021 13:17:11 -0700 [thread overview]
Message-ID: <20210716201724.54804-39-matthew.brost@intel.com> (raw)
In-Reply-To: <20210716201724.54804-1-matthew.brost@intel.com>
From: John Harrison <John.C.Harrison@Intel.com>
Use the official driver default scheduling policies for configuring
the GuC scheduler rather than a bunch of hardcoded values.
v2:
(Matthew Brost)
- Move I915_ENGINE_WANT_FORCED_PREEMPTION to later patch
