Subject: [PATCH 1/2] drm/i915/tgl: the BCS engine supports relative MMIO
Date: Wed, 9 Oct 2019 16:04:23 -0700 [thread overview]
Message-ID: <20191009230424.6507-1-daniele.ceraolospurio@intel.com> (raw)
The specs don't mention any specific HW limitation on the blitter and
manual inspection shows that the HW does set the relative MMIO bit in
the LRI of the blitter context image, so we can remove our limitations.
