RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 MMIO region in Tdx guest is set with PcdTdxSharedBitMask in TdxDxe's entry point. In SEV guest the page table entries is set with PcdPteMemoryEncryptionAddressOrMask when creating 1:1 identity table. So the AddressEncMask in GetPageTableEntry (@CpuPageTable.c) is either PcdPteMemoryEncryptionAddressOrMask (in SEV guest), or PcdTdxSharedBitMask (in TDX guest), or all-0 (in Legacy guest).
