1100 The frame buffer device provides an abstraction for the graphics
1101 hardware. It represents the frame buffer of some video hardware and
1102 allows application software to access the graphics hardware through
1103 a well-defined interface, so the software doesn't need to know
1104 anything about the low-level (hardware register) stuff.
1105
1106 Frame buffer devices work identically across the different
1107 architectures supported by Linux and make the implementation of
1108 application programs easier and more portable; at this point, an X
1109 server exists which uses the frame buffer device exclusively.
1110 On several non-X86 architectures, the frame buffer device is the
1111 only way to use the graphics hardware.
1112
1113 The device is accessed through special device nodes, usually located
1114 in the /dev directory, i.e. /dev/fb*.
1115
1116 You need an utility program called fbset to make full use of frame
1117 buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
1118 and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>
1119 for more information.
1120
1121 Say Y here and to the driver for your graphics board below if you
1122 are compiling a kernel for a non-x86 architecture.
1123
1124 If you are compiling for the x86 architecture, you can say Y if you
1125 want to play with it, but it is not essential. Please note that
1126 running graphical applications that directly touch the hardware
1127 (e.g. an accelerated X server) and that are not frame buffer
1128 device-aware may cause unexpected results. If unsure, say N.
