Subject: [PATCH] MdeModulePkg: Add dynamic PCD
Date: Tue, 7 Feb 2017 13:53:42 -0600	[thread overview]
Message-ID: <1486497223-22694-1-git-send-email-leo.duran@amd.com> (raw)

The new PcdPteMemoryEncryptionAddressOrMask dynamic PCD holds the address
mask for page table entries when memory encryption is enabled on AMD
processors supporting the Secure Encrypted Virtualization (SEV) feature.

This mask should be applied when creating 1:1 virtual to physical mapping tables.
For example, the OvmfPkg sets the PCD when launching SEV-enabled guests.
