Subject: [RFC PATCH 08/13] drm/xe: Stub out execlists deadline vfuncs as NOPs
Date: Wed, 24 Dec 2025 17:17:29 -0800	[thread overview]
Message-ID: <20251225011734.341683-9-matthew.brost@intel.com> (raw)
In-Reply-To: <20251225011734.341683-1-matthew.brost@intel.com>

The execlists backend is non-functional but shouldn’t crash. Stub out
execlists deadline vfuncs as NOPs.
