Subject: [Intel-gfx] [PATCH 1/2] drm/i915/gt: Declare when we enabled timeslicing
Date: Fri, 14 Feb 2020 23:19:16 +0000 [thread overview]
Message-ID: <20200214231917.4055677-1-chris@chris-wilson.co.uk> (raw)
Let userspace know if they can trust timeslicing by including it as part
of the I915_PARAM_HAS_SCHEDULER::I915_SCHEDULER_CAP_TIMESLICING
Fixes: 8ee36e048c98 ("drm/i915/execlists: Minimalistic timeslicing")
