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 EventHead

@param MemoryDescriptorSize

Size of a memory descriptor that is return by GetMemoryMap().

Version of a memory descriptor that is return by GetMemoryMap().

the memory map returned via GetMemoryMap().

Pointer to MemoryMapPhysical that is updated to virtual mode after SetVirtualAddressMap().

Boolean that is TRUE if SetVirtualAddressMap() has been called.
