        tristate "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_CFB_FILLRECT
        tristate
        depends on FB
        default n
        ---help---
          Include the cfb_fillrect function for generic software rectangle
          filling. This is used by drivers that don't provide their own
          (accelerated) version.

config FB_CFB_COPYAREA
        tristate
        depends on FB
        default n
        ---help---
          Include the cfb_copyarea function for generic software area copying.
          This is used by drivers that don't provide their own (accelerated)
          version.

config FB_CFB_IMAGEBLIT
        tristate
        depends on FB
        default n
        ---help---
          Include the cfb_imageblit function for generic software image
          blitting. This is used by drivers that don't provide their own
          (accelerated) version.

config FB_MACMODES

       default 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.

          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>.

          set of values), you'll be able to use any combination of horizontal 
          and vertical resolutions, and vertical refresh rates without having
          to specify your own timing parameters.  This is especially useful

          The driver starts in monitor mode. You must use the matroxset tool 
          (available at <ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/>) to 
          swap primary and secondary head outputs, or to change output mode.  
          Secondary head driver always start in 640x480 resolution and you

          Do not forget that second head supports only 16 and 32 bpp
          packed pixels, so it is a good idea to compile them into the kernel

          for the different Matrox devices. This method is slightly faster but
