The TSC_AUX Virtualization feature allows AMD SEV-ES guests to securely use TSC_AUX (auxiliary time stamp counter data) MSR in RDTSCP and RDPID instructions. The TSC_AUX MSR is typically initialized to APIC ID or another unique identifier so that software can quickly associate returned TSC value with the logical processor. Add the feature bit and also include it in the kvm for detection.

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.
