tcx -- Sun accelerated 8/24-bit color frame buffer
tcx* at sbus? slot ? offset ?
The tcx is a memory based color frame buffer, with graphics acceleration
and overlay capabilities. Its control registers, colour lookup table and
pixel memory can be mapped into a user process address space by using the
mmap(2) system call. The tcx driver supports the minimal ioctl's needed
to run Xorg(1), and can be operated in sparc/cgthree(4) emulation mode.
