Runtime Architectural Protocol as defined in DXE CIS
|
|
|
|
This code is used to produce the EFI 1.0 runtime virtual switch over
|
|
|
|
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 need
|
|
by this driver to produce the runtime transition to virtual mode
|
|
calling.

@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.
