For AMX support it is recommended to load XCR0 after XFD, so that KVM does not see XFD=0, XCR=1 for a save state that will eventually be disabled (which would lead to premature allocation of the space required for that save state). It is also required to load XSAVE data after XCR0 and XFD, so that KVM can trigger allocation of the extra space required to store AMX state. Adjust vcpu_load_state to obey these new requirements.

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.
