Linux环境下视频显示卡设备的驱动程序源代码

	  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.

	  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.
