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.

GT non-engine registers (referred to as "GSI" registers by the spec) have the same relative offsets on standalone media as they do on the primary GT, just with an additional "GSI offset" added to their MMIO address. If we store this GSI offset in the standalone media's intel_uncore structure, it can be automatically applied to all GSI reg reads/writes that happen on that GT, allowing us to re-use our existing GT code with minimal changes. Forcewake and shadowed register tables for the media GT (which will be added in a future patch) are listed as final addresses that already include the GSI offset, so we also need to add the GSI offset before doing lookups of registers in one of those tables. v2: - Add comment on raw_reg_*() macros explaining why we don't bother with GSI offsets in them.
