Latest Intel platform Granite Rapids/Sierra Forest has introduced below new instructions and CPUIDs:
- CMPccXADD CPUID.(EAX=7,ECX=1):EAX[bit 7] - AMX-FP16 CPUID.(EAX=7,ECX=1):EAX[bit 21] - AVX-IFMA CPUID.(EAX=7,ECX=1):EAX[bit 23] - AVX-VNNI-INT8 CPUID.(EAX=7,ECX=1):EDX[bit 4] - AVX-NE-CONVERT CPUID.(EAX=7,ECX=1):EDX[bit 5] - PREFETCHITI CPUID.(EAX=7,ECX=1):EDX[bit 14] Details can be found in recent Intel ISE (Instruction Set Extensions)[1]. Linux 6.2 will support for advertising these features to userspace. KVM patches have been merged into kvm/next[2]. This patch series adds CPUID definitions of the corresponding features in QEMU.
