KVM: Expose new cpu features to guest
Intel IceLake cpu has added new cpu features,AVX512_VBMI2/GFNI/ VAES/VPCLMULQDQ/AVX512_VNNI/AVX512_BITALG. Those new cpu features need expose to guest VM. The bit definition: CPUID.(EAX=7,ECX=0):ECX[bit 06] AVX512_VBMI2 CPUID.(EAX=7,ECX=0):ECX[bit 08] GFNI CPUID.(EAX=7,ECX=0):ECX[bit 09] VAES CPUID.(EAX=7,ECX=0):ECX[bit 10] VPCLMULQDQ CPUID.(EAX=7,ECX=0):ECX[bit 11] AVX512_VNNI CPUID.(EAX=7,ECX=0):ECX[bit 12] AVX512_BITALG The release document ref below link: https://software.intel.com/sites/default/files/managed/c5/15/\ architecture-instruction-set-extensions-programming-reference.pdf The kernel dependency commit in kvm.git: (c128dbfa) Signed-off-by: Yang Zhong <yang.zhong@intel.com> Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>
