Subject: [RFC PATCH v2 01/10] OvmfPkg/Include: Define SEV specific CPUID and MSR
Date: Tue, 21 Mar 2017 17:12:49 -0400 [thread overview]
Message-ID: <149013076888.27235.3173588515291478806.stgit@brijesh-build-machine> (raw)
In-Reply-To: <149013076154.27235.10725020825643505862.stgit@brijesh-build-machine>
The patch defines AMD's Memory Encryption Information CPUID leaf (0x8000_001F).
The complete description for this CPUID leaf is available in APM volume 2 [1]
Section 15.34 (Secure Encrypted Virtualization).
