[edk2] [PATCH 0/3] Add PCD PcdPteMemoryEncryptionAddressOrMask

Posted by Leo Duran 7 years, 8 months ago

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 v1:
- Move PCD to [PcdsFixedAtBuild, ... et al] section in .DEC file
- Add PCD for page tables built by MdeModulePkg/../CapsulePei
- Add PCd for page tables built by UefiCpuPkg/../S3Resume2Pei
