The following chipsets are supported: - -<itemize> -<item> 6422 - - Old chipset. The driver is still very unstable and has computer - crashes. You should use XFree86 3.3.x for this chipset. - - -<item> AT24 - - As found in Diamond Stealth Video 2500. Quite similar to AT3D. - -<item> AT25, AT3D - - AT3D is found in Hercules Stingray 128/3D. Most other Voodoo - Rush based cards use the AT25 which is identical except it - doesn't have the 3D stuff in it. -</itemize> - -<sect> Acceleration -<p> -The apm driver uses the XAA in the -SVGA server. It has support for the following acceleration: - -<itemize> -<item> Bitblts (rectangle copy operation) -<item> Lines (solid, single pixel) -<item> Filled rectangles -<item> CPU->Screen image transfers. -<item> CPU->Screen colour expansion (text accel). -<item> Screen->Screen colour expansion (cached text accel). -<item> Mono 8x8 pattern fill.

In 24bpp mode only Bitblts and Filled rectangles -is supported. Also VESA DPMS power save mode is fully supported with "standby", -"suspend" and "off" modes (set with with the "xset dpms" command). - -<sect> DGA -<p> -Full DGA 2.0 support with framebuffer access and drawing acceleration. - -<sect> Video -<p> -It has limited hardware support for video decoding on the AT24 and AT25/3D. It can -also display an image in YUV colours inside the desktop. There are some more exotic -formats such as YUV 4.1.1, YUV 4.0.0 and RGB 8,16.32bpp. - -<sect> Shadow framebuffer -<p> -There is a mode, called shadow framebuffer, where the graphics are used -to display the images. All rendering is done in memory in a so-called shadow -framebuffer. This mode is useful if you need lots of reading in the video -memory and to use it you will have to put -<verb> - Option "ShadowFB" -</verb> - -in your xorg.conf file. - -<sect> Configuration -<p> -First: Run the xorgconfig program to create a correct -configuration. - -You can turn off hardware cursor by inserting the following line in the -Device section of the xorg.conf file: -<verb> - Option "SWcursor" -</verb> - -Or turn off hardware acceleration: -<verb> - Option "noaccel" -</verb> - -Or turn off MMIO - -<verb> - Option "nolinear" -</verb> - -Do not specify either the amount of video RAM or which chipset -in the config file. It is better to let the driver probe for this. Also -don't put any "clocks" line in the device section since these chips have -a fully programmable clock that can almost take any modeline you throw -at it. It might though fail at some specific clock values but in that case -you should just try a slightly different clock and it should work. - -<sect> glide2x -<p> -There is support for the XF86Rush extension for use with the glide2x library. - -<sect> Questions -<p> -Any questions regarding this driver should be sent to Loïc -Grenié. It should be possible to add support for the 3210 chipset -if someone needs it. - - -</article> |
