AMX was introduced in QEMU commit 1f16764f7d4515bfd5e4ae0aae814fa280a7d0c8 and following commits.
Some of them not pushed yet I believe: https://lists.gnu.org/archive/html/qemu-devel/2022-08/msg01936.html Otherwise the patch looks good (I'm not sure what's the planned usage of the python script, but this patch just adds features that'd be missing in the future, so I think it's fine).
