The number of virtual address bits is something that should be tracked at the platform level rather than the IP level. Even when mixing and matching various graphics, media, and display IP blocks, the platform as a whole has to have consistent page table handling. This is also a trait that should be tied to the platform even if the graphics IP itself is not present (e.g., if we disable the primary GT via configfs). v2: - Drop the default value of 48 and explicitly set it in each relevant descriptor. (Lucas, Michal) v3: - Drop an outdated comment about default value.

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.
