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.
