TVTWO(4) BSD Programmer's Manual (SPARC) TVTWO(4)
tvtwo - accelerated 24-bit color frame buffer
tvtwo* at sbus? slot ? offset ?
wsdisplay* at tvtwo?
The tvtwo is a memory based color frame buffer, with graphics accelera-
tion and overlay capabilities, and hardware MPEG decoding.
The tvtwo driver interfaces the frame buffer to 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.

This driver does not support any acceleration features at the moment.
Thus, vertical scrolling in console mode is abysmally slow in 24 bit
mode.
