Runtime Architectural Protocol as defined in PI Specification VOLUME 2 DXE\r
\r
- This code is used to produce the UEFI 2.0 runtime virtual switch over\r
-\r
- This driver must add SetVirtualAddressMap () and ConvertPointer () to\r
- the EFI system table. This driver is not responcible for CRCing the \r
- EFI system table.\r
-\r
- This driver will add EFI_RUNTIME_ARCH_PROTOCOL_GUID protocol with a \r
- pointer to the Runtime Arch Protocol instance structure. The protocol\r
- member functions are used by the DXE core to export information need\r
- by this driver to produce the runtime transition to virtual mode\r
- calling.\r

+ Allows the runtime functionality of the DXE Foundation to be contained \r

+ export information that is needed at runtime. As such, this protocol allows \r
+ services to the DXE Foundation to manage runtime drivers and events. \r
+ This protocol also implies that the runtime services required to transition \r
+ to virtual mode, SetVirtualAddressMap() and ConvertPointer(), have been \r
+ registered into the UEFI Runtime Table in the UEFI System Table. This protocol \r
+ must be produced by a runtime DXE driver and may only be consumed by the DXE Foundation.\r
