	depends on FB && SH_DREAMCAST
	---help---
	  Say Y here if you have a PowerVR 2 card in your box.  If you plan to
	  run linux on your Dreamcast, you will have to say Y here.
	  This driver may or may not work on other PowerVR 2 cards, but is
	  totally untested.  Use at your own risk.  If unsure, say N.

	  To compile this driver as a module, choose M here: the
	  module will be called pvr2fb.

	  You can pass several parameters to the driver at boot time or at
	  module load time.  The parameters look like "video=pvr2:XXX", where
	  the meaning of XXX can be found at the end of the main source file
	  (<file:drivers/video/pvr2fb.c>). Please see the file

config FB_I810_GTF
	bool "use VESA Generalized Timing Formula"
	depends on FB_I810
	help
	  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.

config FB_MATROX
	tristate "Matrox acceleration"
	depends on FB && PCI
	---help---
	  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>.

config FB_MATROX_MILLENIUM
	bool "Millennium I/II support"
	depends on FB_MATROX
	help
	  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.

config FB_MATROX_MYSTIQUE
	bool "Mystique support"
	depends on FB_MATROX
	help
	  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.

config FB_MATROX_G450
	bool "G100/G200/G400/G450/G550 support"
	depends on FB_MATROX
	---help---
	  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" and "I2C bit-banging 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.

config FB_MATROX_G100A
	bool "G100/G200/G400 support"
	depends on FB_MATROX && !FB_MATROX_G450
	---help---
	  Say Y here if you have a Matrox G100, G200 or G400 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" and "I2C bit-banging support" in the character devices
	  section, and then to "Matrox I2C support" and "G400 second head
	  support" here in the framebuffer section.

config FB_MATROX_G100
	bool
	depends on FB_MATROX && (FB_MATROX_G450 || FB_MATROX_G100A)
	default y

config FB_MATROX_I2C
	tristate "Matrox I2C support"
	depends on FB_MATROX && I2C
	select I2C_ALGOBIT
	---help---
	  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.

config FB_MATROX_MAVEN
	tristate "G400 second head support"
	depends on FB_MATROX_G100 && FB_MATROX_I2C
	---help---
	  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).

config FB_MATROX_MULTIHEAD
	bool "Multihead support"
	depends on FB_MATROX
	---help---
	  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.

config FB_RADEON_OLD
	tristate "ATI Radeon display support (Old driver)"
	depends on FB && PCI
	help
	  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.
	  There is a product page at
