-Module Name:
-
- UnixUgaDriver.c
-
-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.
