Now that we have intel_ggtt_read_entry() we can easily read out the first PTE of the BIOS FB and verify that it looks correct. We'll also use the extracted dma address to figure out where in stolen the FB lives (so far we've just assumed that it sits at offset 0, and in practice that does seem to be true, but better safe than sorry).

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 reStructuredText 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.
