From: Zhao Liu <[email protected]> As SDM stated, CPUID 0x12 leaves depend on CPUID_7_0_EBX_SGX (SGX feature word).
Since FEAT_SGX_12_0_EAX, FEAT_SGX_12_0_EBX and FEAT_SGX_12_1_EAX define multiple feature words, add the dependencies of those registers to report the warning to user if SGX is absent.
