17	  The frame buffer device provides an abstraction for the graphics
18	  hardware. It represents the frame buffer of some video hardware and
19	  allows application software to access the graphics hardware through
20	  a well-defined interface, so the software doesn't need to know
21	  anything about the low-level (hardware register) stuff.
22
23	  Frame buffer devices work identically across the different
24	  architectures supported by Linux and make the implementation of
25	  application programs easier and more portable; at this point, an X
26	  server exists which uses the frame buffer device exclusively.
27	  On several non-X86 architectures, the frame buffer device is the
28	  only way to use the graphics hardware.
29
30	  The device is accessed through special device nodes, usually located
31	  in the /dev directory, i.e. /dev/fb*.
32
33	  You need an utility program called fbset to make full use of frame
34	  buffer devices. Please read <file:Documentation/fb/framebuffer.rst>
35	  and the Framebuffer-HOWTO at
36	  <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
37	  information.
38
39	  Say Y here and to the driver for your graphics board below if you
40	  are compiling a kernel for a non-x86 architecture.
41
42	  If you are compiling for the x86 architecture, you can say Y if you
43	  want to play with it, but it is not essential. Please note that
44	  running graphical applications that directly touch the hardware
45	  (e.g. an accelerated X server) and that are not frame buffer
46	  device-aware may cause unexpected results. If unsure, say N.

48config FIRMWARE_EDID

54	  transfers do not work for your driver and if you are using
55	  nvidiafb, i810fb or savagefb.
56
57	  In general, choosing Y for this option is safe.  If you
58	  experience extremely long delays while booting before you get
59	  something on your display, try setting this to N.  Matrox cards in
60	  combination with certain motherboards and monitors are known to
61	  suffer from this problem.

200	  where the screen is divided into rectangular sections (tiles), whereas
201	  the standard blitting divides the screen into pixels. Because the
202	  default drawing element is a tile, drawing functions will be passed
203	  parameters in terms of number of tiles instead of number of pixels.
204	  For example, to draw a single character, instead of using bitmaps,
205	  an index to an array of bitmaps will be used.  To clear or move a
206	  rectangular section of a screen, the rectangle will be described in
207	  terms of number of tiles in the x- and y-axis.
208

2054	  This is a `virtual' frame buffer device. It operates on a chunk of
2055	  unswappable kernel memory instead of on the memory of a graphics
2056	  board. This means you cannot see any output sent to this frame
2057	  buffer device, while it does consume precious memory. The main use
2058	  of this frame buffer device is testing and debugging the frame
2059	  buffer subsystem. Do NOT enable it for normal systems! To protect
2060	  the innocent, it has to be enabled explicitly at boot time using the
2061	  kernel option `video=vfb:'.
2062
2063	  To compile this driver as a module, choose M here: the
2064	  module will be called vfb. In order to load it, you must use
