Module Name:
Runtime.h
Abstract:
Runtime Architectural Protocol as defined in DXE CIS.
This code is used to produce the EFI runtime services that are callable
only in physical mode.
This driver must add SetVirtualAddressMap () and ConvertPointer () to
the EFI system table. This driver is not responcible for CRCing the
EFI system table.
This driver will add EFI_RUNTIME_ARCH_PROTOCOL_GUID protocol with a
pointer to the Runtime Arch Protocol instance structure. The protocol
member functions are used by the DXE core to export information needed
by this driver to produce the runtime transition of runtime drivers from
physical mode calling to virtual mode calling.

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