SEV-ES adds a new VMEXIT reason code, VMGEXIT. Initial support for a VMGEXIT includes mapping the GHCB based on the guest GPA, which is obtained from a new VMCB field, and then validating the required inputs for the VMGEXIT exit reason. Since many of the VMGEXIT exit reasons correspond to existing VMEXIT reasons, the information from the GHCB is copied into the VMCB control exit code areas and KVM register areas. The standard exit handlers are invoked, similar to standard VMEXIT processing. Before restarting the vCPU, the GHCB is updated with any registers that have been updated by the hypervisor.

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.
