config FB
	bool "Support for frame buffer devices"
	---help---
	  The frame buffer device provides an abstraction for the graphics
	  hardware. It represents the frame buffer of some video hardware and
	  allows application software to access the graphics hardware through
	  a well-defined interface, so the software doesn't need to know
	  anything about the low-level (hardware register) stuff.

	  Frame buffer devices work identically across the different
	  architectures supported by Linux and make the implementation of
	  application programs easier and more portable; at this point, an X
	  server exists which uses the frame buffer device exclusively.
	  On several non-X86 architectures, the frame buffer device is the
	  only way to use the graphics hardware.

	  The device is accessed through special device nodes, usually located
	  in the /dev directory, i.e. /dev/fb*.

	  You need an utility program called fbset to make full use of frame
	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
	  and the Framebuffer-HOWTO at
	  <http://www.tahallah.demon.co.uk/programming/prog.html> for more
	  information.

	  Say Y here and to the driver for your graphics board below if you
	  are compiling a kernel for a non-x86 architecture.

	  If you are compiling for the x86 architecture, you can say Y if you
	  want to play with it, but it is not essential. Please note that
	  running graphical applications that directly touch the hardware
	  (e.g. an accelerated X server) and that are not frame buffer
	  device-aware may cause unexpected results. If unsure, say N.

config FB_CIRRUS
	tristate "Cirrus Logic support"
	depends on FB && (AMIGA || PCI) && BROKEN
	---help---
	  This enables support for Cirrus Logic GD542x/543x based boards on
	  Amiga: SD64, Piccolo, Picasso II/II+, Picasso IV, or EGS Spectrum.

	  If you have a PCI-based system, this enables support for these
	  chips: GD-543x, GD-544x, GD-5480.

	  Please read the file <file:Documentation/fb/cirrusfb.txt>.

	  Say N unless you have such a graphics board or plan to get one
	  before you next recompile the kernel.

config FB_STI
	tristate "HP STI frame buffer device support"

	default y
	---help---
	  STI refers to the HP "Standard Text Interface" which is a set of
	  BIOS routines contained in a ROM chip in HP PA-RISC based machines.
	  Enabling this option will implement the linux framebuffer device
	  using calls to the STI BIOS routines for initialisation.
	
	  If you enable this option, you will get a planar framebuffer device
	  /dev/fb which will work on the most common HP graphic cards of the
	  NGLE family, including the artist chips (in the 7xx and Bxxx series),
	  HCRX, HCRX24, CRX, CRX24 and VisEG series.

	  It is safe to enable this option, so you should probably say "Y".
