We do not currently document the requirements for configuration of the SVE system registers when booting the kernel, let's do so for completeness. We don't have a hard requirement that the vector lengths configured on different CPUs on initial boot be consistent since we have logic to constrain to the minimum supported value but we will reject any late CPUs which can't support the current maximum and introducing the concept of late CPUs seemed more complex than was useful so we require that all CPUs use the same value.

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.
