Windows guest driver needs vbt in opregion, to configure the setting for display. Without opregion support, the display registers won't be set and this blocks display model to get the correct information of the guest display plane. This patch is to provide a virtual opregion for guest. The original author of this patch is Xiaoguang Chen. This patch is split from the "Dma-buf support for GVT-g" patch set, with being rebased to the latest gvt-staging branch. v3: - add checking region index during intel_vgpu_rw. (Xiong) v2: - refine intel_vgpu_reg_release_opregion. (Xiong) Here are the previous version comments: v18: - unmap vgpu's opregion when destroying vgpu. v16: - rebase to 4.14.0-rc6.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
