Hi,
This series addes new instrucions and CPU model support for Intel
Diamond Rapids.
This series mainly includes:
* MOVRS CPUID
* new AMX CPUIDs
* AVX10.2 & AVX10_VNNI_INT
* DMR CPU model & topology documentation
- The on-going cache-aware scheduling work could benefit such
topology:

This series is based on https://gitlab.com/bonzini/qemu i386 branch at
7c7e2f410b3d ("target/i386/tcg: mark APX as supported").
Compared with v1, v2 mainly did:
* allow upsupported avx10 version when x-force-feature=on, for debug.
* rename CPUID_7_1_EDX_APX to CPUID_7_1_EDX_APXF in DMR CPU model.
One More Thing
==============
About the AVX10 model (patch 4), in principle, AVX10.1 should be allowed
to run on an AVX10.2 host. For similar version drived features,
introducing a model might be a preferable way. However, PMU doesn't
serve as a good example here.
Thanks for your review!
Best Regards,
Zhao
