Intel SGX 2 related stuff can be discussed in this issue.

I haven't seen a CPU that really is SGX 2 capable yet. Some CPUs return sgx 2 supported: 1 but none of these CPU's can be configured to execute SGX because it cannot be enabled in BIOS (eg. Cloud vendors, MacBooks).

It would be great if someone is able to share information regarding the usage of SGX 2 and the release of SGX2 capable CPU's because I get a few e-mails regarding that topic.

printf("\nCPUID Leaf 12H, Sub-Leaf 0 of Intel SGX Capabilities (EAX=12H,ECX=0)\n");
eax = 0x12;
ecx = 0;
native_cpuid(&eax, &ebx, &ecx, &edx);
printf("sgx 1 supported: %d\n", eax & 0x1);
printf("sgx 2 supported: %d\n", (eax >> 1) & 0x1);
printf("MaxEnclaveSize_Not64: %x\n", edx & 0xFF);
printf("MaxEnclaveSize_64: %x\n", (edx >> 8) & 0xFF);
