the sgx programming reference says that EXITINFO field can support #PF #GP exceptions if SECS.MISCSELECT.EXINFO = 1. In the section 2.7.2 about SECS.MISCSELECT field, If CPUID(EAX=12H, ECX=0):EBX[31:0]=0, SECS.MISCSELECT field must be all zeros. I have checked almost all of our lab's computers supported SGX. They are EBX=0. so they must set this field zeros. otherwise, the SGX driver will report error.
So, is there some cpus to support this features now? In the paper “SGX-LAPD: Thwarting Controlled Side Channel Attacks via Enclave Veriﬁable Page Faults”, their experiments use core i5-6200U to support the page fault exception inside enclave. But I don't have this cpu, I can't test it.
How can I get the details of each cpuid's result? Has intel provided a database to let me see the cpuid results for different leafs about each cpu?
