- Console Splitter Driver. Any Handle that attatched console I/O protocols
- (Console In device, Console Out device, Console Error device, Simple Pointer
- protocol, Absolute Pointer protocol) can be bound by this driver.
-
- 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
- splitter, one for console output splitter and one for error output splitter.
- These 3 virtual handles would be installed on gST.
-
- Each virtual handle, that supports the 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.

- (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.
-
- @param This Protocol instance pointer.
- @param BltBuffer Buffer containing data to blit into video buffer. This
- buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)
- @param BltOperation Operation to perform on BlitBuffer and video memory
- @param SourceX X coordinate of source for the BltBuffer.
- @param SourceY Y coordinate of source for the BltBuffer.
- @param DestinationX X coordinate of destination for the BltBuffer.
- @param DestinationY Y coordinate of destination for the BltBuffer.
- @param Width Width of rectangle in BltBuffer in pixels.
- @param Height Hight of rectangle in BltBuffer in pixels.
- @param Delta OPTIONAL
-
- @retval EFI_SUCCESS The Blt operation completed.
- @retval EFI_INVALID_PARAMETER BltOperation is not valid.
- @retval EFI_DEVICE_ERROR A hardware error occured writting to the video buffer.
