This patch introduces a new function intel_vgpu_reset_cfg_space() to reset vGPU configuration space. This function will unmap gttmmio and aperture if they are mapped before. Then entire cfg space will be restored to default values. Currently we only do such reset when vGPU is not owned by any VM so we simply restore entire cfg space to default value, not following the PCIe FLR spec that some fields should remain unchanged.

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.
