Should we (can do it, if you already don't have a patch WIP for it)
also update this file to reflect this?
https://git.qemu.org/?p=qemu.git;a=blob;f=docs/qemu-cpu-models.texi
While at it ... I wonder if it's worth making a separte doc
(versioned-cpu-models.rst) explaining the versioned CPU models, usage,
etc.
There was a very useful discussion between you and Dan Berrangé on this
list (Message-Id: <20190625050008.12789-5-ehabkost@redhat.com>, the
first version of the thread: "[PATCH 4/6] i386: Infrastructure for
versioned CPU models"). Could potentially incorporate some of that
content.
