The cgfour is a color frame buffer with overlay plane for the P4 bus of sun4 class workstations.

The cgfour driver interfaces the frame buffer with the wscons(4) console framework. It does not provide direct device driver entry points but makes its functions available via the internal wsdisplay(4) interface.
