CONFIG_FB_SGIVW
SGI Visual Workstation support for framebuffer graphics.
CONFIG_VIDEO_SELECT
This enables support for text mode selection on kernel startup. If
you want to take advantage of some high-resolution text mode your
card's BIOS offers, but the traditional Linux utilities like
SVGATextMode don't, you can say Y here and set the mode using the
"vga=" option from your boot loader (lilo or loadlin) or set
"vga=ask" which brings up a video mode menu on kernel startup. (Try
"man bootparam" or see the documentation of your boot loader about
how to pass options to the kernel.)
Read the file <file:Documentation/svga.txt> for more information
about the Video mode selection support. If unsure, say N.
CONFIG_FB
The frame buffer device provides an abstraction for the graphics
hardware. It represents the frame buffer of some video hardware and
......@@ -242,14 +229,6 @@ CONFIG_FB_VESA
You will get a boot time penguin logo at no additional cost. Please
read <file:Documentation/fb/vesafb.txt>. If unsure, say Y.
CONFIG_FBCON_VGA_PLANES
This low level frame buffer console driver enable the kernel to use
the 16-color planar modes of the old VGA cards where the bits of
each pixel are separated into 4 planes.
Only answer Y here if you have a (very old) VGA card that isn't VESA
2 compatible.
CONFIG_FB_VGA16
This is the frame buffer device driver for VGA 16 color graphic
cards. Say Y if you have such a card.
......@@ -263,74 +242,15 @@ CONFIG_FB_VGA16
CONFIG_FB_STI
STI refers to the HP "Standard Text Interface" which is a set of
BIOS routines contained in a ROM chip in HP PA-RISC based machines.
Enabling this option will implement the linux framebuffer device and
an fbcon color text console using calls to the STI BIOS routines.
The HP framebuffer device is usually planar, uses a strange memory
layout, and changing the plane mask to create colored pixels
requires a call to the STI routines, so do not expect /dev/fb to
actually be useful. However, it is the best we have as far as
graphics on the HP chipsets due to lack of hardware level
documentation for the various on-board HP chipsets used in these
systems. It is sufficient for basic text console functions,
including fonts.
You should probably enable this option, unless you are having
trouble getting video when booting the kernel (make sure it isn't
just that you are running the console on the serial port, though).
Really old HP boxes may not have STI, and must use the PDC BIOS
console or the IODC BIOS.
CONFIG_FBCON_FONTS
Say Y here if you would like to use fonts other than the default
your frame buffer console usually use.
Note that the answer to this question won't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about foreign fonts.
If unsure, say N (the default choices are safe).
CONFIG_FONT_8x16
This is the "high resolution" font for the VGA frame buffer (the one
provided by the VGA text console 80x25 mode.
If unsure, say Y.
CONFIG_FBCON_FONTWIDTH8_ONLY
Answer Y here will make the kernel provide only the 8x8 fonts (these
are the less readable).
If unsure, say N.
CONFIG_FONT_SUN8x16
This is the high resolution console font for Sun machines. Say Y.
CONFIG_FONT_SUN12x22
This is the high resolution console font for Sun machines with very
big letters (like the letters used in the SPARC PROM). If the
standard font is unreadable for you, say Y, otherwise say N.
CONFIG_FONT_8x8
This is the "high resolution" font for the VGA frame buffer (the one
provided by the text console 80x50 (and higher) modes).
Enabling this option will implement the linux framebuffer device
using calls to the STI BIOS routines for initialisation.
Note that this is a poor quality font. The VGA 8x16 font is quite a
lot more readable.
If you enable this option, you will get a planar framebuffer device
/dev/fb which will work on the most common HP graphic cards of the
NGLE family, including the artist chips (in the 7xx and Bxxx series),
HCRX, HCRX24, CRX, CRX24 and VisEG series.
Given the resolution provided by the frame buffer device, answer N
here is safe.
CONFIG_FONT_6x11
Small console font with Macintosh-style high-half glyphs. Some Mac
framebuffer drivers don't support this one at all.
CONFIG_FONT_PEARL_8x8
Small console font with PC-style control-character and high-half
glyphs.
CONFIG_FONT_ACORN_8x8
Small console font with PC-style control characters and high-half
glyphs.
It is safe to enable this option, so you should probably say "Y".
CONFIG_FB_HGA
Say Y here if you have a Hercules mono graphics card.
......@@ -646,79 +566,3 @@ CONFIG_FB_SA1100
If you plan to use the LCD display with your SA-1100 system, say
Y here.
CONFIG_FBCON_ADVANCED
The frame buffer console uses character drawing routines that are
tailored to the specific organization of pixels in the memory of
your graphics hardware. These are called the low level frame buffer
console drivers. Note that they are used for text console output
only; they are NOT needed for graphical applications.
If you say N here, the needed low level drivers are automatically
enabled, depending on what frame buffer devices you selected above.
This is recommended for most users.
If you say Y here, you have more fine-grained control over which low
level drivers are enabled. You can e.g. leave out low level drivers
for color depths you do not intend to use for text consoles.
Low level frame buffer console drivers can be modules ( = code which
can be inserted and removed from the running kernel whenever you
want). The modules will be called fbcon-*.o. If you want to compile
(some of) them as modules, read <file:Documentation/modules.txt>.
If unsure, say N.
CONFIG_FBCON_MFB
This is the low level frame buffer console driver for monochrome
(2 colors) packed pixels.
CONFIG_FBCON_CFB2
This is the low level frame buffer console driver for 2 bits per
pixel (4 colors) packed pixels.
CONFIG_FBCON_CFB4
This is the low level frame buffer console driver for 4 bits per
pixel (16 colors) packed pixels.
CONFIG_FBCON_CFB8
This is the low level frame buffer console driver for 8 bits per
pixel (256 colors) packed pixels.
CONFIG_FBCON_CFB16
This is the low level frame buffer console driver for 15 or 16 bits
per pixel (32K or 64K colors, also known as `hicolor') packed
pixels.
CONFIG_FBCON_CFB24
This is the low level frame buffer console driver for 24 bits per
pixel (16M colors, also known as `truecolor') packed pixels. It is
NOT for `sparse' 32 bits per pixel mode.
CONFIG_FBCON_CFB32
This is the low level frame buffer console driver for 32 bits per
pixel (16M colors, also known as `truecolor') sparse packed pixels.
CONFIG_FBCON_AFB
This is the low level frame buffer console driver for 1 to 8
bitplanes (2 to 256 colors) on Amiga.
CONFIG_FBCON_ILBM
This is the low level frame buffer console driver for 1 to 8
interleaved bitplanes (2 to 256 colors) on Amiga.
CONFIG_FBCON_IPLAN2P2
This is the low level frame buffer console driver for 2 interleaved
bitplanes (4 colors) on Atari.
CONFIG_FBCON_IPLAN2P4
This is the low level frame buffer console driver for 4 interleaved
bitplanes (16 colors) on Atari.
CONFIG_FBCON_IPLAN2P8
This is the low level frame buffer console driver for 8 interleaved
bitplanes (256 colors) on Atari.
CONFIG_FBCON_HGA

CONFIG_VIDEO_SELECT
This enables support for text mode selection on kernel startup. If
you want to take advantage of some high-resolution text mode your
card's BIOS offers, but the traditional Linux utilities like
SVGATextMode don't, you can say Y here and set the mode using the
"vga=" option from your boot loader (lilo or loadlin) or set
"vga=ask" which brings up a video mode menu on kernel startup. (Try
"man bootparam" or see the documentation of your boot loader about
how to pass options to the kernel.)
Read the file <file:Documentation/svga.txt> for more information
about the Video mode selection support. If unsure, say N.
CONFIG_FBCON_FONTS
Say Y here if you would like to use fonts other than the default
your frame buffer console usually use.
Note that the answer to this question won't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about foreign fonts.
If unsure, say N (the default choices are safe).
CONFIG_FONT_8x16
This is the "high resolution" font for the VGA frame buffer (the one
provided by the VGA text console 80x25 mode.
If unsure, say Y.
CONFIG_FBCON_FONTWIDTH8_ONLY
Answer Y here will make the kernel provide only the 8x8 fonts (these
are the less readable).
If unsure, say N.
CONFIG_FONT_SUN8x16
This is the high resolution console font for Sun machines. Say Y.
CONFIG_FONT_SUN12x22
This is the high resolution console font for Sun machines with very
big letters (like the letters used in the SPARC PROM). If the
standard font is unreadable for you, say Y, otherwise say N.
CONFIG_FONT_8x8
This is the "high resolution" font for the VGA frame buffer (the one
provided by the text console 80x50 (and higher) modes).
Note that this is a poor quality font. The VGA 8x16 font is quite a
lot more readable.
Given the resolution provided by the frame buffer device, answer N
here is safe.
CONFIG_FONT_6x11
Small console font with Macintosh-style high-half glyphs. Some Mac
framebuffer drivers don't support this one at all.
CONFIG_FONT_PEARL_8x8
Small console font with PC-style control-character and high-half
glyphs.
CONFIG_FONT_ACORN_8x8
Small console font with PC-style control characters and high-half
glyphs.
CONFIG_FBCON_ADVANCED
The frame buffer console uses character drawing routines that are
tailored to the specific organization of pixels in the memory of
your graphics hardware. These are called the low level frame buffer
console drivers. Note that they are used for text console output
only; they are NOT needed for graphical applications.
If you say N here, the needed low level drivers are automatically
enabled, depending on what frame buffer devices you selected above.
This is recommended for most users.
If you say Y here, you have more fine-grained control over which low
level drivers are enabled. You can e.g. leave out low level drivers
for color depths you do not intend to use for text consoles.
Low level frame buffer console drivers can be modules ( = code which
can be inserted and removed from the running kernel whenever you
want). The modules will be called fbcon-*.o. If you want to compile
(some of) them as modules, read <file:Documentation/modules.txt>.
If unsure, say N.
CONFIG_FBCON_AFB
This is the low level frame buffer console driver for 1 to 8
bitplanes (2 to 256 colors) on Amiga.
CONFIG_FBCON_ILBM
This is the low level frame buffer console driver for 1 to 8
interleaved bitplanes (2 to 256 colors) on Amiga.
CONFIG_FBCON_IPLAN2P2
This is the low level frame buffer console driver for 2 interleaved
bitplanes (4 colors) on Atari.
CONFIG_FBCON_IPLAN2P4
This is the low level frame buffer console driver for 4 interleaved
bitplanes (16 colors) on Atari.
CONFIG_FBCON_IPLAN2P8
This is the low level frame buffer console driver for 8 interleaved
bitplanes (256 colors) on Atari.
CONFIG_FBCON_HGA
This is the low level frame buffer console driver for Hercules mono
graphics cards.

YWRAP/YPAN+MOVE/YMOVE. On the other side, if you have a fast bus
and even better if your card can do fonting (1->8/32bit painting),
you should consider either SCROLL_YREDRAW (if your card is
able to do neither YPAN/YWRAP), or SCROLL_YNOMOVE.
The best is to test it with some real life scrolling (usually, not
all lines on the screen are filled completely with non-space characters,
and REDRAW performs much better on such lines, so don't cat a file
with every line covering all screen columns, it would not be the right
benchmark).
