Subject: [PATCH v3 0/4] Add PCD PcdPteMemoryEncryptionAddressOrMask
Date: Thu, 16 Feb 2017 15:02:02 -0600 [thread overview]
Message-ID: <1487278926-14303-1-git-send-email-leo.duran@amd.com> (raw)
This new 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 is be applied when creating 1:1 virtual to physical mapping tables.
For example, the OvmfPkg sets the PCD when launching SEV-enabled guests.
Changes since v2:
- Apply mask to PCD to keep value within Address field
- Use variable instead of PCD in Page-Fault Handler
To-Do:
- Add PCD support for page tables in UefiCpuPg/PiSmmCpuDxeSmm
