If bit 22 of Group B Features is set, the guest has access to the Isolation Configuration CPUID leaf. On x86, the first four bits of EAX in this leaf provide the isolation type of the partition; we entail three isolation types: 'SNP' (hardware-based isolation), 'VBS' (software-based isolation), and 'NONE' (no isolation).

README
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.
