Cirrus Logic 5430 Controller Driver.
|
||||
This driver is a sample implementation of the UGA Draw and Graphics Output
|
||||
Protocols for the Cirrus Logic 5430 family of PCI video controllers.
|
||||
This driver is only usable in the EFI pre-boot environment.
|
||||
This sample is intended to show how the UGA Draw and Graphics output Protocol
|
||||
is able to function.
|
||||
The UGA I/O Protocol is not implemented in this sample.
|
||||
A fully compliant EFI UGA driver requires both
|
||||
the UGA Draw and the UGA I/O Protocol. Please refer to Microsoft's
|
||||
documentation on UGA for details on how to write a UGA driver that is able
|
||||
to function both in the EFI pre-boot environment and from the OS runtime.
