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 Berrang=E9 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. > --- > target/i386/cpu.c | 5 +++++ > 1 file changed, 5 insertions(+) [...] --=20 /kashyap
