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. This enables support for native frame buffer device (fbdev) drivers. The DRM subsystem provides support for emulated frame buffer devices on top of KMS drivers, but this option allows legacy fbdev drivers to be enabled as well. 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 you need support for G400 secondary head, you must say Y to "Matrox I2C support" and "G400 second head support" right below. 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_I2C tristate "Matrox I2C support" depends on FB_MATROX select FB_DDC 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_G && 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.
