[PULL 14/36] i386: Add primary SGX CPUID and MSR defines |
Date: |
Mon, 6 Sep 2021 15:10:37 +0200 |
From: Sean Christopherson <sean.j.christopherson@intel.com>
Add CPUID defines for SGX and SGX Launch Control (LC), as well as
defines for their associated FEATURE_CONTROL MSR bits. Define the
Launch Enclave Public Key Hash MSRs (LE Hash MSRs), which exist
when SGX LC is present (in CPUID), and are writable when SGX LC is
enabled (in FEATURE_CONTROL).
