        ---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.rst>
          and the Framebuffer-HOWTO at
          <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.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 FIRMWARE_EDID
        bool "Enable firmware EDID"
        depends on FB
        ---help---
          This enables access to the EDID transferred from the firmware.
          On the i386, this is from the Video BIOS. Enable this if DDC/I2C
          transfers do not work for your driver and if you are using
          nvidiafb, i810fb or savagefb.

          In general, choosing Y for this option is safe.  If you
          experience extremely long delays while booting before you get
          something on your display, try setting this to N.  Matrox cards in
          combination with certain motherboards and monitors are known to
          suffer from this problem.

          non-native endianness (e.g. Little-Endian framebuffer on a
          Big-Endian machine). Most probably you don't have such hardware,
          so it's safe to say "n" here.

          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
        ---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.

          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),

          G450/G550 secondary head and digital output are supported without
          additional modules.

          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
          must use fbset to change it.

          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
          too. You can use only some font widths, as the driver uses generic
          painting procedures (the secondary head does not use acceleration
          engine).

          the fbdev driver on first head and the fbdev driver on second head.

          If you compile it as module, two modules are created,
          matroxfb_crtc2 and matroxfb_maven. Matroxfb_maven is needed for
          both G200 and G400, matroxfb_crtc2 is needed only by G400. You must
          also load i2c-matroxfb to get it to run.

          tool (available at

          This is a `virtual' frame buffer device. It operates on a chunk of
          unswappable kernel memory instead of on the memory of a graphics
          board. This means you cannot see any output sent to this frame
          buffer device, while it does consume precious memory. The main use
          of this frame buffer device is testing and debugging the frame
          buffer subsystem. Do NOT enable it for normal systems! To protect
          the innocent, it has to be enabled explicitly at boot time using the
          kernel option `video=vfb:'.

          To compile this driver as a module, choose M here: the
          module will be called vfb. In order to load it, you must use
          the vfb_enable=1 option.
