Do you have datasheet link? It's better to add the link in the commit
message for easy comparison checking.

LGTM,

BTW, Could you please update the CPU model you added in
docs/system/cpu-models-x86.rst.inc (section "Preferred CPU models for
Intel x86 hosts") as well? Although this document has been inactive for
some time, it hasn't been deprecated, and we can pick it up again to
continue updating it, helping QEMU users understand QEMU's support for
x86 CPU/features.
Thanks,
Zhao
