As well as a number of simple features which only add new instructions and require corresponding hwcaps SME2 introduces a new register ZT0 for which we must define ABI. Fortunately this is a fixed size 512 bits and therefore much more straightforward than the base SME state, the only wrinkle is that it is only accessible when ZA is accessible. While there is only a single register the architecture is written with a view to exensibility, including a number in the name, so follow this in the ABI.

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.
