Support for frame buffer devices

    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.


Frame buffer hardware drivers
FB_CIRRUS
Cirrus Logic support

    This enables support for Cirrus Logic GD542x/543x based boards on
    Amiga: SD64, Piccolo, Picasso II/II+, Picasso IV, or EGS Spectrum.

    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.

FB_NVIDIA
nVidia Framebuffer Support

    This driver supports graphics boards with the nVidia chips, TNT
    and newer. For very old chipsets, such as the RIVA128, then use
    the rivafb.
    Say Y if you have such a graphics board.

    To compile this driver as a module, choose M here: the
    module will be called nvidiafb.


FB_NVIDIA_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.

    Say Y here if you want the nVidia driver to output all sorts
    of debugging information to provide to the maintainer when
    something goes wrong.

    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.

    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.

    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.

    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
DDC/I2C for Intel framebuffer support

    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

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:'.
