MTL has separate forcewake tables for the primary/render GT and the media GT; each GT's intel_uncore will use a separate forcewake table and should only initialize the domains that are relevant to that GT. The GT ack register also moves to a new location of (GSI base + 0xDFC) on this platform. Note that although our uncore handlers take care of transparently redirecting all register accesses in the media GT's GSI range to their new offset at 0x380000, the forcewake ranges listed in the table should use the final, post-translation offsets. NOTE: There are two ranges in the media IP that have multicast registers where the two register instances reside in different power wells (either VD0 or VD2). We don't have an easy way to deal with this today (and in fact we don't even access these register ranges in the driver today), so for now we just mark those ranges as FORCEWAKE_ALL which will cause all of the media power wells to be grabbed, ensuring proper operation. If we start reading/writing in those ranges in the future, we can re-visit whether it's worth adding extra steering complexity into our forcewake support.

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.
