Currently it will take the snapshot of the MCHBAR registers for gvt-g initialization so that it can be used for guest vgpu. And it will cover from 0x140000 to 0x17ffff. In fact based on the HW spec most of them are meanlingless and some time is wasted to read these register. Only the range of 0x144000 to 0x147fff contains the valid definition. So the range of capturing I915 MCHBAR register is refined, which helps to optimize the gvt-g boot time.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
