So far it works like any other driver by opening a SimpleTextIn and/or
SimpleTextOut protocol with EFI_OPEN_PROTOCOL_BY_DRIVER attributes. The big
difference is this driver does not layer a protocol on the passed in
handle, or construct a child handle like a standard device or bus driver.
This driver produces three virtual handles as children, one for console input
handle, or construct a child handle like a standard device or bus driver.
This driver produces three virtual handles as children, one for console input
splitter, one for console output splitter and one for error output splitter.
EFI_CONSOLE_SPLIT_PROTOCOL will be attatched onto each virtual handle to
EFI_CONSOLE_SPLIT_PROTOCOL will be attatched onto each virtual handle to
identify the splitter type.
Each virtual handle, that supports both the EFI_CONSOLE_SPLIT_PROTOCOL
and Console I/O protocol, will be produced in the driver entry point.
and Console I/O protocol, will be produced in the driver entry point.
The virtual handle are added on driver entry and never removed.
Such design ensures sytem function well during none console device situation.

Routine Description:
The following table defines actions for BltOperations:
EfiUgaVideoFill - Write data from the BltBuffer pixel (SourceX, SourceY)
directly to every pixel of the video display rectangle
(DestinationX, DestinationY)
(DestinationX + Width, DestinationY + Height).
Only one pixel will be used from the BltBuffer. Delta is NOT used.
EfiUgaVideoToBltBuffer - Read data from the video display rectangle
(SourceX, SourceY) (SourceX + Width, SourceY + Height) and place it in
the BltBuffer rectangle (DestinationX, DestinationY )
(DestinationX + Width, DestinationY + Height). If DestinationX or
DestinationY is not zero then Delta must be set to the length in bytes
of a row in the BltBuffer.
EfiUgaBltBufferToVideo - Write data from the BltBuffer rectangle
(SourceX, SourceY) (SourceX + Width, SourceY + Height) directly to the
video display rectangle (DestinationX, DestinationY)
(DestinationX + Width, DestinationY + Height). If SourceX or SourceY is
not zero then Delta must be set to the length in bytes of a row in the
BltBuffer.
EfiUgaVideoToVideo - Copy from the video display rectangle
(SourceX, SourceY) (SourceX + Width, SourceY + Height) .
to the video display rectangle (DestinationX, DestinationY)
(DestinationX + Width, DestinationY + Height).
The BltBuffer and Delta are not used in this mode.
Arguments:
This - Protocol instance pointer.
BltBuffer - Buffer containing data to blit into video buffer. This
buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)
BltOperation - Operation to perform on BlitBuffer and video memory
SourceX - X coordinate of source for the BltBuffer.
SourceY - Y coordinate of source for the BltBuffer.
DestinationX - X coordinate of destination for the BltBuffer.
DestinationY - Y coordinate of destination for the BltBuffer.
Width - Width of rectangle in BltBuffer in pixels.
Height - Hight of rectangle in BltBuffer in pixels.
Delta -
Returns:
EFI_SUCCESS - The Blt operation completed.
EFI_INVALID_PARAMETER - BltOperation is not valid.
EFI_DEVICE_ERROR - A hardware error occured writting to the video
buffer.
