[PATCH v3 10/25] x86/sgx: Add SGX2 ENCLS leaf definitions (EAUG, EMODPR and EMODT)

From: Kai Huang
Date: Fri Mar 19 2021 - 03:24:34 EST


From: Sean Christopherson <sean.j.christopherson@xxxxxxxxx>

Define the ENCLS leafs that are available with SGX2, also referred to as
Enclave Dynamic Memory Management (EDMM). The leafs will be used by KVM
to conditionally expose SGX2 capabilities to guests.
