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_MODE_HELPERS
        bool "Enable Video Mode Handling Helpers"
        depends on FB
	default n
	---help---
	  This enables functions for handling video modes using the
	  Generalized Timing Formula and the EDID parser. A few drivers rely
          on this feature such as the radeonfb, rivafb, and the i810fb. If
	  your driver does not take advantage of this feature, choosing Y will
	  just increase the kernel size by about 5K.

config FB_TILEBLITTING
       bool "Enable Tile Blitting Support"
       depends on FB
       default n
       ---help---
         This enables tile blitting.  Tile blitting is a drawing technique
	 where the screen is divided into rectangular sections (tiles), whereas
	 the standard blitting divides the screen into pixels. Because the
	 default drawing element is a tile, drawing functions will be passed
	 parameters in terms of number of tiles instead of number of pixels.
	 For example, to draw a single character, instead of using bitmaps,
	 an index to an array of bitmaps will be used.  To clear or move a
	 rectangular section of a screen, the rectangle will be described in
	 terms of number of tiles in the x- and y-axis.

	 This is particularly important to one driver, matroxfb.  If
	 unsure, say N.

config FB_CIRRUS
	tristate "Cirrus Logic support"
	depends on FB && (ZORRO || PCI)
	---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_PM2
	tristate "Permedia2 support"
	depends on FB && ((AMIGA && BROKEN) || PCI)
	help

	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".
