Runtime Architectural Protocol as defined in PI Specification VOLUME 2 DXE
|
|
|
|
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
|
|
services to 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 UEFI Runtime Table in the UEFI System Table. This protocol
|
|
must be produced by a runtime DXE driver and may only be consumed by the DXE Foundation.
