VFs do not have direct access to the GMDID register and must obtain its value from the GuC. Since we need GMDID value very early in the driver probe flow, before we even start the full setup of GT and GuC data structures, we must do some early initializations ourselves. Additionally, since we also need GMDID for the media GT, which isn't created yet, temporarly tweak the root GT type into MEDIA to allow communication with the correct GuC, as only it can provide the value of the media GMDID register.

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.
