Subject: [PATCH 09/10] drm/i915: Add new function to copy subslices for a slice
Date: Fri, 2 Aug 2019 13:51:33 -0700 [thread overview]
Message-ID: <20190802205134.303-10-stuart.summers@intel.com> (raw)
In-Reply-To: <20190802205134.303-1-stuart.summers@intel.com>
Add a new function to copy subslices for a specified slice
between intel_sseu structures for the purpose of determining
power-gate status.
