Unfortunately, I can only direct you to - "7.4 Virtual Memory Services" in the UEFI spec (at one point it says "The SetVirtualAddressMap() and ConvertPointer() services are only callable in physical mode", - as an example, the efi_enter_virtual_mode() function in the Linux kernel, file "arch/x86/platform/efi/efi.c".
