If we pay closer attention to struct gmdid_map, we will realize that it
is actually fully describing an IP (graphics or media): it contains
"release info" and "features info". The former is comprised of fields
"ver" and "name"; and the latter is done via member "ip", which is a
pointer to either struct xe_graphics_desc or xe_media_desc, and can be
reused across releases.
As such let's:
* Rename struct gmdid_map to xe_ip.
* Rename the field ver to verx100 to be consistent with the naming of
members using that encoding of the version.
* Rename the field "ip" to "desc" to make it clear that it is a
pointer to a descriptor of features for the IP, since it will not
contain *all* info (i.e. features + release info).
We sill have release info mapped into struct xe_{graphics,media}_desc
for pre-GMDID IPs. In an upcoming change we will handle that so that we
make a clear separation between "release info" and "feature info".

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.
