Description: Support for frame buffer devices

More info: 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.rst> and the Framebuffer-HOWTO at <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.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.
