## Video configuration#menu "Graphics support" depends on HAS_IOMEMsource "drivers/char/agp/Kconfig"source "drivers/char/drm/Kconfig"config VGASTATE tristate default nconfig VIDEO_OUTPUT_CONTROL tristate "Lowlevel video output switch controls" help This framework adds support for low-level control of the video output switch.menuconfig 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 FIRMWARE_EDID bool "Enable firmware EDID" depends on FB default n ---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_DDC tristate depends on FB select I2C_ALGOBIT select I2C default nconfig 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_CFB_REV_PIXELS_IN_BYTE bool depends on FB default n ---help--- Allow generic frame-buffer functions to work on displays with 1, 2 and 4 bits per pixel depths which has opposite order of pixels in byte order to bytes in long order.config FB_SYS_FILLRECT tristate depends on FB default n ---help--- Include the sys_fillrect function for generic software rectangle filling. This is used by drivers that don't provide their own (accelerated) version and the framebuffer is in system RAM.config FB_SYS_COPYAREA tristate depends on FB default n ---help--- Include the sys_copyarea function for generic software area copying. This is used by drivers that don't provide their own (accelerated) version and the framebuffer is in system RAM.config FB_SYS_IMAGEBLIT tristate depends on FB default n ---help--- Include the sys_imageblit function for generic software image blitting. This is used by drivers that don't provide their own (accelerated) version and the framebuffer is in system RAM.config FB_SYS_FOPS tristate depends on FB default nconfig FB_DEFERRED_IO bool depends on FB default yconfig FB_SVGALIB tristate depends on FB default n ---help--- Common utility functions useful to fbdev drivers of VGA-based cards.config FB_MACMODES tristate depends on FB default nconfig FB_BACKLIGHT bool depends on FB select BACKLIGHT_LCD_SUPPORT select BACKLIGHT_CLASS_DEVICE default nconfig 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.comment "Frame buffer hardware drivers" depends on FBconfig 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>.
