<pre>
 
    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.munted.org.uk/programming/Framebuffer-HOWTO-1.2.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.
 
 
 
FIRMWARE_EDID
 
Enable firmware EDID
 
 
    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.
 
 
 
FB_BOOT_VESA_SUPPORT
 
 
    If true, at least one selected framebuffer driver can take advantage
 
    of VESA video modes set at an early boot stage via the vga= parameter.
 
 
 
FB_CFB_FILLRECT
 
 
    Include the cfb_fillrect function for generic software rectangle
 
    filling. This is used by drivers that don't provide their own
 
    (accelerated) version.
 
 
 
FB_CFB_COPYAREA
 
 
    Include the cfb_copyarea function for generic software area copying.
 
    This is used by drivers that don't provide their own (accelerated)
 
    version.
 
 
 
FB_CFB_IMAGEBLIT
 
 
    Include the cfb_imageblit function for generic software image
 
    blitting. This is used by drivers that don't provide their own
 
    (accelerated) version.
 
 
 
FB_CFB_REV_PIXELS_IN_BYTE
 
 
    Allow generic frame-buffer functions to work on displays with 1, 2
 
    and 4 bits per pixel depths which has opposite order of pixels in
 
    byte order to bytes in long order.
 
 
 
FB_SYS_FILLRECT
 
 
    Include the sys_fillrect function for generic software rectangle
 
    filling. This is used by drivers that don't provide their own
 
    (accelerated) version and the framebuffer is in system RAM.
 
 
 
FB_SYS_COPYAREA
 
 
    Include the sys_copyarea function for generic software area copying.
 
    This is used by drivers that don't provide their own (accelerated)
 
    version and the framebuffer is in system RAM.
 
 
 
FB_SYS_IMAGEBLIT
 
 
    Include the sys_imageblit function for generic software image
 
    blitting. This is used by drivers that don't provide their own
 
    (accelerated) version and the framebuffer is in system RAM.
 
 
 
FB_FOREIGN_ENDIAN
 
Framebuffer foreign endianness support
 
 
    This menu will let you enable support for the framebuffers with
 
    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.
 
 
 
FB_SVGALIB
 
 
    Common utility functions useful to fbdev drivers of VGA-based
 
    cards.
 
 
 
FB_MODE_HELPERS
 
Enable Video Mode Handling Helpers
 
 
    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.
 
 
 
FB_TILEBLITTING
 
Enable Tile Blitting Support
 
 
    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.

    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.

    If you want to compile this as a module (=code which can be
 
    inserted into and removed from the running kernel), say M
 
    here and read <file:Documentation/kbuild/modules.txt>.  The module
 
    will be called amba-clcd.

    This driver supports graphics boards with the nVidia Riva/Geforce
 
    chips.
 
    Say Y if you have such a graphics board.
 
 
    To compile this driver as a module, choose M here: the
 
    module will be called rivafb.
 
 
 
FB_RIVA_I2C
 
Enable DDC Support
 
 
    This enables I2C support for nVidia Chipsets.  This is used
 
    only for getting EDID information from the attached display
 
    allowing for robust video mode handling and switching.
 
 
    Because fbdev-2.6 requires that drivers must be able to
 
    independently validate video mode parameters, you should say Y
 
    here.
 
 
 
FB_RIVA_DEBUG
 
Lots of debug output
 
 
    Say Y here if you want the Riva driver to output all sorts
 
    of debugging information to provide to the maintainer when
 
    something goes wrong.
 
 
 
FB_RIVA_BACKLIGHT
 
Support for backlight control
 
 
    Say Y here if you want to control the backlight of your display.
 
 
 
FB_I810
 
Intel 810/815 support (EXPERIMENTAL)
 
 
    This driver supports the on-board graphics built in to the Intel 810
 
    and 815 chipsets.  Say Y if you have and plan to use such a board.
 
 
    To compile this driver as a module, choose M here: the
 
    module will be called i810fb.
 
 
    For more information, please read
 
    <file:Documentation/fb/intel810.txt>
 
 
FB_I810_GTF
 
use VESA Generalized Timing Formula
 
 
    If you say Y, then the VESA standard, Generalized Timing Formula
 
    or GTF, will be used to calculate the required video timing values
 
    per video mode.  Since the GTF allows nondiscrete timings
 
    (nondiscrete being a range of values as opposed to discrete being a
 
    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
 
    to maximize the performance of an aging display, or if you just
 
    have a display with nonstandard dimensions. A VESA compliant
 
    monitor is recommended, but can still work with non-compliant ones.
 
    If you need or want this, then select this option. The timings may
 
    not be compliant with Intel's recommended values. Use at your own
 
    risk.
 
 
    If you say N, the driver will revert to discrete video timings
 
    using a set recommended by Intel in their documentation.
 
 
    If unsure, say N.

Intel 830M/845G/852GM/855GM/865G/915G/945G/945GM/965G/965GM support (EXPERIMENTAL)
 
 
    This driver supports the on-board graphics built in to the Intel
 
    830M/845G/852GM/855GM/865G/915G/915GM/945G/945GM/965G/965GM chipsets.
 
    Say Y if you have and plan to use such a board.
 
 
    If you say Y here and want DDC/I2C support you must first say Y to
 
    "I2C support" and "I2C bit-banging support" in the character devices
 
    section.
 
 
    If you say M here then "I2C support" and "I2C bit-banging support"
 
    can be build either as modules or built-in.
 
 
    To compile this driver as a module, choose M here: the
 
    module will be called intelfb.
 
 
    For more information, please read <file:Documentation/fb/intelfb.txt>
 
 
FB_INTEL_DEBUG
 
Intel driver Debug Messages
 
 
    Say Y here if you want the Intel driver to output all sorts
 
    of debugging information to provide to the maintainer when
 
    something goes wrong.
 
 
 
FB_INTEL_I2C

    Say Y here if you want DDC/I2C support for your on-board Intel graphics.
 
 
 
FB_MATROX
 
Matrox acceleration
 
 
    Say Y here if you have a Matrox Millennium, Matrox Millennium II,
 
    Matrox Mystique, Matrox Mystique 220, Matrox Productiva G100, Matrox
 
    Mystique G200, Matrox Millennium G200, Matrox Marvel G200 video,
 
    Matrox G400, G450 or G550 card in your box.
 
 
    To compile this driver as a module, choose M here: the
 
    module will be called matroxfb.
 
 
    You can pass several parameters to the driver at boot time or at
 
    module load time. The parameters look like "video=matrox:XXX", and
 
    are described in <file:Documentation/fb/matroxfb.txt>.
 
 
 
FB_MATROX_MILLENIUM
 
Millennium I/II support
 
 
    Say Y here if you have a Matrox Millennium or Matrox Millennium II
 
    video card. If you select "Advanced lowlevel driver options" below,
 
    you should check 4 bpp packed pixel, 8 bpp packed pixel, 16 bpp
 
    packed pixel, 24 bpp packed pixel and 32 bpp packed pixel. You can
 
    also use font widths different from 8.
 
 
 
FB_MATROX_MYSTIQUE
 
Mystique support
 
 
    Say Y here if you have a Matrox Mystique or Matrox Mystique 220
 
    video card. If you select "Advanced lowlevel driver options" below,
 
    you should check 8 bpp packed pixel, 16 bpp packed pixel, 24 bpp
 
    packed pixel and 32 bpp packed pixel. You can also use font widths
 
    different from 8.
 
 
 
FB_MATROX_G
 
G100/G200/G400/G450/G550 support
 
 
    Say Y here if you have a Matrox G100, G200, G400, G450 or G550 based
 
    video card. If you select "Advanced lowlevel driver options", you
 
    should check 8 bpp packed pixel, 16 bpp packed pixel, 24 bpp packed
 
    pixel and 32 bpp packed pixel. You can also use font widths
 
    different from 8.
 
 
    If you need support for G400 secondary head, you must first say Y to
 
    "I2C support" in the character devices section, and then to
 
    "Matrox I2C support" and "G400 second head support" here in the
 
    framebuffer section. 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).
 
 
    G450/G550 hardware can display TV picture only from secondary CRTC,
 
    and it performs no scaling, so picture must have 525 or 625 lines.
 
 
 
FB_MATROX_I2C
 
Matrox I2C support
 
 
    This drivers creates I2C buses which are needed for accessing the
 
    DDC (I2C) bus present on all Matroxes, an I2C bus which
 
    interconnects Matrox optional devices, like MGA-TVO on G200 and
 
    G400, and the secondary head DDC bus, present on G400 only.
 
 
    You can say Y or M here if you want to experiment with monitor
 
    detection code. You must say Y or M here if you want to use either
 
    second head of G400 or MGA-TVO on G200 or G400.
 
 
    If you compile it as module, it will create a module named
 
    i2c-matroxfb.
 
 
 
FB_MATROX_MAVEN
 
G400 second head support
 
 
    WARNING !!! This support does not work with G450 !!!
 
 
    Say Y or M here if you want to use a secondary head (meaning two
 
    monitors in parallel) on G400 or MGA-TVO add-on on G200. Secondary
 
    head is not compatible with accelerated XFree 3.3.x SVGA servers -
 
    secondary head output is blanked while you are in X. With XFree
 
    3.9.17 preview you can use both heads if you use SVGA over fbdev or
 
    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.
 
 
    The driver starts in monitor mode and you must use the matroxset
 
    tool (available at
 
    <ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/>) to switch it to
 
    PAL or NTSC or to swap primary and secondary head outputs.
 
    Secondary head driver also always start in 640x480 resolution, you
 
    must use fbset to change it.
 
 
    Also 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).
 
 
 
FB_MATROX_MULTIHEAD
 
Multihead support
 
 
    Say Y here if you have more than one (supported) Matrox device in
 
    your computer and you want to use all of them for different monitors
 
    ("multihead"). If you have only one device, you should say N because
 
    the driver compiled with Y is larger and a bit slower, especially on
 
    ia32 (ix86).
 
 
    If you said M to "Matrox unified accelerated driver" and N here, you
 
    will still be able to use several Matrox devices simultaneously:
 
    insert several instances of the module matroxfb into the kernel
 
    with insmod, supplying the parameter "dev=N" where N is 0, 1, etc.
 
    for the different Matrox devices. This method is slightly faster but
 
    uses 40 KB of kernel memory per Matrox card.
 
 
    There is no need for enabling 'Matrox multihead support' if you have
 
    only one Matrox card in the box.
 
 
 
FB_RADEON
 
ATI Radeon display support
 
 
    Choose this option if you want to use an ATI Radeon graphics card as
 
    a framebuffer device.  There are both PCI and AGP versions.  You
 
    don't need to choose this to run the Radeon in plain VGA mode.
 
 
    If you say Y here and want DDC/I2C support you must first say Y to
 
    "I2C support" and "I2C bit-banging support" in the character devices
 
    section.
 
 
    If you say M here then "I2C support" and "I2C bit-banging support"
 
    can be build either as modules or built-in.

    color operation, with depths ranging from 1 bpp to 8 bpp monochrome
 
    and 8, 15 or 16 bpp color; 90 degrees clockwise display rotation for
 
    panels <= 320 pixel horizontal resolution.
 
 
 
FB_VIRTUAL
 
Virtual Frame Buffer support (ONLY FOR TESTING!)
 
 
    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.
 
 
    If unsure, say N.
 
 
 
XEN_FBDEV_FRONTEND
 
Xen virtual frame buffer support
 
 
    This driver implements the front-end of the Xen virtual

    in another domain.
 
 
 
FB_METRONOME
 
E-Ink Metronome/8track controller support
 
 
    This driver implements support for the E-Ink Metronome
 
    controller. The pre-release name for this device was 8track
 
    and could also have been called by some vendors as PVI-nnnn.
 
 
 
FB_MB862XX
 
Fujitsu MB862xx GDC support
 
 
    Frame buffer driver for Fujitsu Carmine/Coral-P(A)/Lime controllers.

    This enables framebuffer support for Fujitsu Carmine/Coral-P(A)
 
    PCI graphics controller devices.
 
 
 
FB_MB862XX_LIME
 
Lime GDC
 
 
    Framebuffer support for Fujitsu Lime GDC on host CPU bus.
 
 
 
FB_PRE_INIT_FB
 
Don't reinitialize, use bootloader's GDC/Display configuration
 
 
    Select this option if display contents should be inherited as set by
 
    the bootloader.
 
 
 
FB_MX3
 
MX3 Framebuffer support
 
 
    This is a framebuffer device for the i.MX31 LCD Controller. So
 
    far only synchronous displays are supported. If you plan to use
 
    an LCD display with your i.MX31 system, say Y here.
