cgfourteen
—
Sun accelerated 8/24-bit color frame buffer
The cgfourteen
is a memory based color frame buffer,
with graphics acceleration and overlay capabilities. Its pixel memory can be
mapped into a user process address space by using the
mmap(2) system call. The
cgfourteen
driver supports the minimal ioctl's needed
to run Xorg(1).
The driver operates by default in
sparc/cgthree(4)
emulation mode, i.e. in 8-bit unaccelerated mode. This emulation does
include support for the hardware cursor present on the
cgfourteen
, however.
