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.
