+ @par Protocol 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.
+
+ @param ImageHead
+ A list of type EFI_RUNTIME_IMAGE_ENTRY.

+ @param EventHead
+ A list of type EFI_RUNTIME_EVENT_ENTRY.
+
+ @param MemoryDescriptorSize
+ Size of a memory descriptor that is return by GetMemoryMap().
+
+ @param MemoryDescriptorVersion
+ Version of a memory descriptor that is return by GetMemoryMap().
+
+ @param MemoryMapSize
+ Size of the memory map in bytes contained in MemoryMapPhysical and MemoryMapVirtual.
+
+ @param MemoryMapPhysical
+ Pointer to a runtime buffer that contains a copy of
+ the memory map returned via GetMemoryMap().
+
+ @param MemoryMapVirtual
+ Pointer to MemoryMapPhysical that is updated to virtual mode after SetVirtualAddressMap().
+
+ @param VirtualMode
+ Boolean that is TRUE if SetVirtualAddressMap() has been called.
+
+ @param AtRuntime
+ Boolean that is TRUE if ExitBootServices () has been called.
