1096 The frame buffer device provides an abstraction for the graphics
1097 hardware. It represents the frame buffer of some video hardware and
1098 allows application software to access the graphics hardware through
1099 a well-defined interface, so the software doesn't need to know
1100 anything about the low-level (hardware register) stuff.
1101
1102 Frame buffer devices work identically across the different
1103 architectures supported by Linux and make the implementation of
1104 application programs easier and more portable; at this point, an X
1105 server exists which uses the frame buffer device exclusively.
1106 On several non-X86 architectures, the frame buffer device is the
1107 only way to use the graphics hardware.
1108
1109 The device is accessed through special device nodes, usually located
1110 in the /dev directory, i.e. /dev/fb*.
1111
1112 You need an utility program called fbset to make full use of frame
1113 buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
1114 and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>
1115 for more information.
1116
1117 Say Y here and to the driver for your graphics board below if you
1118 are compiling a kernel for a non-x86 architecture.
1119
1120 If you are compiling for the x86 architecture, you can say Y if you
1121 want to play with it, but it is not essential. Please note that
1122 running graphical applications that directly touch the hardware
1123 (e.g. an accelerated X server) and that are not frame buffer
1124 device-aware may cause unexpected results. If unsure, say N.
