Defining the FGU behaviour is extremely tedious. It relies on matching each set of bits from FGT registers with am architectural feature, and adding them to the FGU list if the corresponding feature isn't advertised to the guest. It is however relatively easy to dump most of that information from the architecture JSON description, and use that to control the FGU bits. Let's introduce a new set of tables descripbing the mapping between FGT bits and features. Most of the time, this is only a lookup in an idreg field, with a few more complex exceptions. While this is obviously many more lines in a new file, this is mostly generated, and is pretty easy to maintain.

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.
