[PATCH v3 1/6] i386: Introduce FeatureWordInfo for AMX CPUID leaf 0x1D and 0x1E

2023-01-06 Thread Lei Wang
CPUID leaf 0x1D and 0x1E enumerate tile and TMUL information for AMX. Introduce FeatureWord FEAT_1D_1_EAX, FEAT_1D_1_EBX, FEAT_1D_1_ECX and FEAT_1E_0_EBX. Thus these features of AMX can be expanded when "-cpu host/max" and can be configured in named CPU model. Signed-off-by: Lei Wang --- target
