SEV-SNP guests are required to perform a GHCB GPA registration. Before using a GHCB GPA for a vCPU the first time, a guest must register the vCPU GHCB GPA. If hypervisor can work with the guest requested GPA then it must respond back with the same GPA otherwise return -1. On VMEXIT, verify that the GHCB GPA matches with the registered value. If a mismatch is detected, then abort the guest.

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 reStructuredText 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.
