Subject: [RFCv2 01/14] drm/i915: factor out i915_pvinfo.h
Date: Thu, 18 Feb 2016 19:42:08 +0800 [thread overview]
Message-ID: <1455795741-3487-2-git-send-email-zhi.a.wang@intel.com> (raw)
In-Reply-To: <1455795741-3487-1-git-send-email-zhi.a.wang@intel.com>
As the PVINFO page definition is used by both GVT-g guest (vGPU) and GVT-g
host (GVT-g kernel device model), factor it out for better code structure.
