Arguments:
|

This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.

ControllerHandle - The handle of a controller that the driver specified by
|

This is managing. This handle specifies the controller
|

whose name is to be returned.
|
||||
ChildHandle - The handle of the child controller to retrieve the name
|

of. This is an optional parameter that may be NULL. It
|
||||
will be NULL for device drivers. It will also be NULL
|
||||
for a bus drivers that wish to retrieve the name of the
|

bus controller. It will not be NULL for a bus driver

Language - A pointer to a three character ISO 639-2 language

string is the name of the controller specified by

|
||||
by Language from the point of view of the driver specified

Abstract:

This file implements the EFI 1.1 Device Driver model requirements for UGA
|

|

UGA is short hand for Universal Graphics Abstraction protocol.
|
||||
|
||||
This file is a verision of UgaIo the uses UnixThunk system calls as an IO
|
||||
abstraction. For a PCI device UnixIo would be replaced with
|
||||
a PCI IO abstraction that abstracted a specific PCI device.

processing is done in a thread kicked off in UnixUgaImplementation.c

Since the window information is processed in an other thread we need

a keyboard Queue to pass data about. The Simple Text In code just

takes data off the Queue. The WinProc message loop takes keyboard input
|

and places it in the Queue.
