Set sev_info.active during SEV/SEV-ES activation before calling any code that can potentially consume sev_info.es_active, e.g. set "active" and "es_active" as a pair immediately after the initial sanity checks. KVM generally expects that es_active can be true if and only if active is true, e.g. sev_asid_new() deliberately avoids sev_es_guest() so that it doesn't get a false negative. This will allow WARNing in sev_es_guest() if the VM is tagged as SEV-ES but not SEV.

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.
