Linux kernel source tree

Rather than storing all characteristics for an entire platform in the xe_device_desc structure, create secondary graphics and media structures to hold traits and feature flags specific to those IPs. This will eventually allow us to assign the graphics and media characteristics at runtime based on the contents of the relevant GMD_ID registers. For now, just move the IP versions into the new structures to keep things simple. Other IP-specific fields will migrate to these structures in future patches. Note that there's one functional change introduced by this: previously PVC was recognized as media version 12.60. That's technically true, but in practice the media engines are fused off on all production hardware. By simply not assigning a media IP structure to PVC it will effectively be treated as IP version 0.0 now (which the rest of the driver should treat as non-existent media). v2: - Split the new structures out to their own header. This will ease the addition of KUnit tests later.

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.
