* This will handles video output using the XBOX' frame buffer. It assumes
|
||||
* the graphics have been set up by Cromwell. This driver uses all video memory
|
||||
* to avoid expensive memcpy()'s.
|
||||
*
|
||||
* It is usuable as console (to see the initial boot) as well as for interactive
|
||||
* use. The latter is handeled using kbd_*() functionality. Keyboard hotplug is
|
||||
* fully supported, the console will periodically rescan if no keyboard was
|
||||
* found.
|
||||
* This is the syscon(4)-ized version of the Xbox Frame Buffer driver. It
|
||||
* supports about all features required, such as mouse support.
|
||||
*
|
||||
* A lot of functions that are not useful to us have not been implemented.
|
||||
* It appears that some functions are never called, but these implementations
|
||||
* are here nevertheless.
