menu "Graphics support"
config FIRMWARE_EDID
bool "Enable firmware EDID"
default y
---help---
This enables access to the EDID transferred from the firmware.
On the i386, this is from the Video BIOS. Enable this if DDC/I2C
transfers do not work for your driver and if you are using
nvidiafb, i810fb or savagefb.
In general, choosing Y for this option is safe. If you
experience extremely long delays while booting before you get
something on your display, try setting this to N. Matrox cards in
combination with certain motherboards and monitors are known to
suffer from this problem.
config FB
tristate "Support for frame buffer devices"
---help---
The frame buffer device provides an abstraction for the graphics
hardware. It represents the frame buffer of some video hardware and
allows application software to access the graphics hardware through
a well-defined interface, so the software doesn't need to know
anything about the low-level (hardware register) stuff.
Frame buffer devices work identically across the different
architectures supported by Linux and make the implementation of
application programs easier and more portable; at this point, an X
server exists which uses the frame buffer device exclusively.
On several non-X86 architectures, the frame buffer device is the
only way to use the graphics hardware.
The device is accessed through special device nodes, usually located
in the /dev directory, i.e. /dev/fb*.
You need an utility program called fbset to make full use of frame
buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
and the Framebuffer-HOWTO at
<http://www.tahallah.demon.co.uk/programming/prog.html> for more
information.
Say Y here and to the driver for your graphics board below if you
are compiling a kernel for a non-x86 architecture.
If you are compiling for the x86 architecture, you can say Y if you
want to play with it, but it is not essential. Please note that
running graphical applications that directly touch the hardware
(e.g. an accelerated X server) and that are not frame buffer
device-aware may cause unexpected results. If unsure, say N.
config FB_CFB_FILLRECT
tristate
depends on FB
default n
---help---
Include the cfb_fillrect function for generic software rectangle
filling. This is used by drivers that don't provide their own
(accelerated) version.
config FB_CFB_COPYAREA
tristate
depends on FB
default n
---help---
Include the cfb_copyarea function for generic software area copying.
This is used by drivers that don't provide their own (accelerated)
version.
config FB_CFB_IMAGEBLIT
tristate
depends on FB
default n
---help---
Include the cfb_imageblit function for generic software image
blitting. This is used by drivers that don't provide their own
(accelerated) version.
config FB_MACMODES
tristate
depends on FB
default n
config FB_BACKLIGHT
bool
depends on FB
select BACKLIGHT_LCD_SUPPORT
select BACKLIGHT_CLASS_DEVICE
default n
config FB_MODE_HELPERS
bool "Enable Video Mode Handling Helpers"
depends on FB
default n
---help---
This enables functions for handling video modes using the
Generalized Timing Formula and the EDID parser. A few drivers rely
on this feature such as the radeonfb, rivafb, and the i810fb. If
your driver does not take advantage of this feature, choosing Y will
just increase the kernel size by about 5K.
config FB_TILEBLITTING
bool "Enable Tile Blitting Support"
depends on FB
default n
---help---
This enables tile blitting. Tile blitting is a drawing technique
where the screen is divided into rectangular sections (tiles), whereas
the standard blitting divides the screen into pixels. Because the
default drawing element is a tile, drawing functions will be passed
parameters in terms of number of tiles instead of number of pixels.
For example, to draw a single character, instead of using bitmaps,
an index to an array of bitmaps will be used. To clear or move a
rectangular section of a screen, the rectangle will be described in
terms of number of tiles in the x- and y-axis.
This is particularly important to one driver, matroxfb. If
unsure, say N.
config FB_CIRRUS
tristate "Cirrus Logic support"
depends on FB && (ZORRO || PCI)
select FB_CFB_FILLRECT
select FB_CFB_COPYAREA
select FB_CFB_IMAGEBLIT
---help---
This enables support for Cirrus Logic GD542x/543x based boards on
Amiga: SD64, Piccolo, Picasso II/II+, Picasso IV, or EGS Spectrum.
If you have a PCI-based system, this enables support for these
chips: GD-543x, GD-544x, GD-5480.
Please read the file <file:Documentation/fb/cirrusfb.txt>.
Say N unless you have such a graphics board or plan to get one
before you next recompile the kernel.
config FB_PM2
tristate "Permedia2 support"
depends on FB && ((AMIGA && BROKEN) || PCI)
select FB_CFB_FILLRECT
select FB_CFB_COPYAREA
select FB_CFB_IMAGEBLIT
help
This is the frame buffer device driver for the Permedia2 AGP frame
buffer card from ASK, aka `Graphic Blaster Exxtreme'. There is a
product page at
<http://www.ask.com.hk/product/Permedia%202/permedia2.htm>.
config FB_PM2_FIFO_DISCONNECT
bool "enable FIFO disconnect feature"
depends on FB_PM2 && PCI
help
Support the Permedia2 FIFO disconnect feature (see CONFIG_FB_PM2).
config FB_ARMCLCD
tristate "ARM PrimeCell PL110 support"

select FB_CFB_FILLRECT
select FB_CFB_COPYAREA
select FB_CFB_IMAGEBLIT
help
This framebuffer device driver is for the ARM PrimeCell PL110
Colour LCD controller. ARM PrimeCells provide the building
blocks for System on a Chip devices.
If you want to compile this as a module (=code which can be
inserted into and removed from the running kernel), say M
here and read <file:Documentation/modules.txt>. The module
will be called amba-clcd.

insert several instances of the module matroxfb into the kernel

for the different Matrox devices. This method is slightly faster but
uses 40 KB of kernel memory per Matrox card.
