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.

49 bool "Enable firmware EDID"

51 help
52 This enables access to the EDID transferred from the firmware.
53 On the i386, this is from the Video BIOS. Enable this if DDC/I2C
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

199 This enables tile blitting. Tile blitting is a drawing technique
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.

601 Due to hardware limitations ZLX-E2 and E3 cards are not supported
602 for DECstation 5000/200 systems. Additionally due to firmware
603 limitations these cards may cause troubles with booting DECstation
604 5000/240 and /260 systems, but are fully supported under Linux if

1021 and vertical resolutions, and vertical refresh rates without having

1152 If you need support for G400 secondary head, you must say Y to
1153 "Matrox I2C support" and "G400 second head support" right below.
1154 G450/G550 secondary head and digital output are supported without
1155 additional modules.
1156
1157 The driver starts in monitor mode. You must use the matroxset tool
1158 (available at <ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/>) to
1159 swap primary and secondary head outputs, or to change output mode.
1160 Secondary head driver always start in 640x480 resolution and you
1161 must use fbset to change it.
1162
1163 Do not forget that second head supports only 16 and 32 bpp
1164 packed pixels, so it is a good idea to compile them into the kernel
1165 too. You can use only some font widths, as the driver uses generic
1166 painting procedures (the secondary head does not use acceleration
1167 engine).
1168
1169 G450/G550 hardware can display TV picture only from secondary CRTC,
1170 and it performs no scaling, so picture must have 525 or 625 lines.
