Three new dynamic PCDs are needed to support SEV-ES under OVMF:
- PcdSevEsIsEnabled: BOOLEAN value used to indicate if SEV-ES is enabled
- PcdGhcbBase: UINT64 value that is the base address of the GHCB
allocation.
- PcdGhcbSize: UINT64 value that is the size, in bytes, of the
GHCB allocation (size is dependent on the number of
APs).
