framebuffer driver for ATI Radeon chipset video boards ====================================================== These files are replacement for linux-2.4.x-ac.y drivers. To use this driver you should have at least linux-2.4.5-ac.1 then simply replace linux/drivers/video/radeon* with files from this directory. Note: since linux-2.4.10 this driver was moved from -ac to Linus distribution. Alternative way: ~~~~~~~~~~~~~~~~ Simply type two commands in this directory: make make install Anyway you should have 'Frame buffer support' compiled into linux-kernel and at least '8bpp packed pixel support' compiled and installed as module. (But if you plan to use this module with mplayer you also should have 16bpp, 24bpp and 32bpp pixel support compiled as modules). Radeon video overlay ==================== Was designed for mplayer and currently can be used only by mplayer. It's RGB-YUV BES for radeon cards (althrough there is experimental support for rage128 / rage128pro chips). Installation: ~~~~~~~~~~~~~ Simply type two commands in this directory: make make install If you install it first time then type also: make nodes Using with mplayer: ~~~~~~~~~~~~~~~~~~~ Currently there is only way to use ATI's drivers: mplayer -vo vesa:lvo:/dev/radeon_vid -<your vesa's options> filename or mplayer -vo vesa:lvo:/dev/rage128_vid -<your vesa's options> filename For YV12 formats you can use also: mplayer -vo mga:/dev/radeon_vid -<your mga's option> filename but in this case you should load at least radeonfb driver from this package. Configuring: ~~~~~~~~~~~~ You can tune up some parameters with using following trick: echo "parameter=value">/dev/radeon_vid Example (disables adaptive deinterlacing): echo "deinterlace=off">/dev/radeon_vid To know more about these parameters - try read /dev/radeon_vid file ;) For example: cat /dev/radeon_vid List of parameters: ~~~~~~~~~~~~~~~~~~~ if you have rage128 chip: brightness=decval (-64:+63) changes brightness saturation=decval (0:+31) changes saturation 0 == grayscaled mode else - if you have radeon: brightness=decval (-1000:+1000) -1000 == black screen saturation=decval (-1000:+1000) -1000 == grayscaled mode contrast=decval (-1000:+1000) -1000 == black screen hue=decval (-1000:+1000) -1000 == +1000 (full circle) all other values are within this range Note: 0 is default value for every parameter on radeons WARNING: This driver violates rule: "no float in the kernel". So if you have problems then don't use color correction and tell me about these problems. double_buff=on/off enables/disables double buffering deinterlace=on/off enables/disables adaprive deinterlacing deinterlace_pattern=hexval defines deinterlacing pattern Driver parameters: ~~~~~~~~~~~~~~~~~~ You can use some additional parameters during module loading: Example: modprobe radeon_vid swap_fourcc=1 List of driver's parameters: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ mtrr=1/0 configures MTRR (if available) default = 1 swap_fourcc=1/0 performs byte swapping of passed fourcc. (It's required for compatibility with -vo mga) To know more about driver's parameters execute: modinfo radeon_vid or modinfo rage128_vid Note: ~~~~~ For command line of mplayer: You can pass only options with can be recognized by vo_vesa driver. (Indeed radeon_vid and rage128_vid are stupid things and can create video overlay only. But mode switching and other adjustement performs vo_vesa driver. This mean that they use VESA BIOS as graphics server). Conslusion: ~~~~~~~~~~~ This stuff (radeon(rage128)_vid) currently doesn't support any standards. So after implementing linux standards I'll fully rewrite this driver. Full example: ~~~~~~~~~~~~~ modprobe radeon_vid mtrr=1 echo "deinterlace_pattern=F0055555">/dev/radeon_vid mplayer -vo vesa:lvo:/dev/radeon_vid -fs -zoom -bpp 32 filename Enjoy!
