NAME

cgtwelveaccelerated 24-bit color frame buffer

SYNOPSIS

cgtwelve* at sbus?
wsdisplay* at cgtwelve?

DESCRIPTION

The cgtwelve is a triple-slot SBus color frame buffer, with graphics acceleration and overlay capabilities.
The cgtwelve 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.

SEE ALSO

intro(4), sbus(4), wscons(4), wsdisplay(4)

CAVEATS

The only way to connect a cgtwelve frame buffer to an UltraSPARC is with the help of an xbox(4) SBus Expansion subsystem.
This driver does not support any acceleration features.
