DESCRIPTION

The cgsix is a low-end graphics accelerator designed to enhance vector and polygon drawing performance.  It has an 8-bit color frame buffer and provides the standard frame buffer interface as defined in fbio(4S). 

The cgsix has registers and memory that may be mapped with mmap(2), using the offsets defined in /usr/include/sundev/cg6reg.h.
