When detecting AMD PMU support for encoding "branch instructions retired" as event 0xc2,0, simply check for Family 17h+ as all Zen CPUs support said encoding, and AMD will maintain the encoding for backwards compatibility on future CPUs. Note, the kernel proper also interprets Family 17h+ as Zen (see the sole caller of init_amd_zen_common()).

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.
