Detailed Description

Allows the runtime functionality of the DXE Foundation to be contained in a separate driver. It also provides hooks for the DXE Foundation to export information that is needed at runtime. As such, this protocol allows the DXE Foundation to manage runtime drivers and events. This protocol also implies that the runtime services required to transition to virtual mode, SetVirtualAddressMap() and ConvertPointer(), have been registered into the EFI Runtime Table in the EFI System Partition. This protocol must be produced by a runtime DXE driver and may only be consumed by the DXE Foundation.
