Extend the PMU counters test to verify KVM emulation of fixed counters in addition to general purpose counters. Fixed counters add an extra wrinkle in the form of an extra supported bitmask. Thus quoth the SDM: fixed-function performance counter 'i' is supported if ECX[i] || (EDX[4:0] > i) Test that KVM handles a counter being available through either method.

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.
