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.

Intel's eXtended Feature Disable (XFD) feature allows the software to dynamically adjust fpstate buffer size for XSAVE features which have large state. Because guest fpstate has been expanded for all possible dynamic xstates at KVM_SET_CPUID2, emulation of the IA32_XFD MSR is straightforward. For write just call fpu_update_guest_xfd() to update the guest fpu container once all the sanity checks are passed. For read simply return the cached value in the container.
