Subject: [PATCH v2 19/22] drm/i915: don't allocate the ring in stolen if we lack aperture
Date: Thu, 3 Oct 2019 20:24:41 +0100 [thread overview]
Message-ID: <20191003192444.10113-20-matthew.auld@intel.com> (raw)
In-Reply-To: <20191003192444.10113-1-matthew.auld@intel.com>
Since we have no way access it from the CPU. For such cases just
fallback to internal objects.
