[PATCH 0/6] Add AVX10.1 CPUID support and GraniteRapids-v2 model

Posted by Tao Su 3 weeks, 5 days ago

Add AVX10.1 CPUID support, i.e. add AVX10 support bit via
CPUID.(EAX=07H, ECX=01H):EDX[bit 19] and new CPUID leaf 0x24H so that
guest OS and applications can query the AVX10 CPUIDs directly. The AVX10.1
spec can be found in [*], it is worth mentioning that
VL128 (CPUID.(EAX=24H, ECX=00H):EBX[bit 16]) was dropped in rev3.0, but it
will be added back and reserved as 1.

Since GraniteRapids (stepping 1) is the first platform to support AVX10,
introduce GraniteRapids-v2 CPU model to add AVX10 in this patch set, and
add some missing features as well.
