[[http://lists.freedesktop.org/archives/xorg/2005-June/008356.html|EXA]] support status for various drivers.  To help out, take a driver that isn't started, or improve one of the patches below, or port the code from KAA or XAA.  Documentation is in xorg git under xserver/xorg/hw/xfree86/doc/devel/exa-driver.txt and found in doxygen from in the exa.h header.

If you want to test, you will need at least
{{{
    Option "AccelMethod" "exa"
}}}
in your card's `Device` section in `xorg.conf`.  Do *not* try `Load "exa"` because it will fail.  You may also want to enable Composite, by saying
{{{
Section "Extensions"
    Option "Composite" "enable"
EndSection
}}}

Supported:

 * i128  (Solid and Copy only so far, incompatible with DGA, only tested on T2``R4 cards)
 * radeon (r1xx-r7xx with Render accel)
 * sis  (sis/xgi; Solid and Copy only)
 * trident cyberblade and xp4 (Solid and Copy only)
 * via (Solid, Copy, Render)
 * savage (Solid, Copy, UTS)
 * mach64 (Solid, Copy, Render. [[https://bugs.freedesktop.org/show_bug.cgi?id=8414|DFS]] pending)
 * mga (Solid, Copy, UTS. [[https://bugs.freedesktop.org/show_bug.cgi?id=1293|Render]] pending)
 * siliconmotion (Solid, Copy. UTS pending)
 * i810/intel (Solid, Copy, Render)
 * nouveau (Solid, Copy, UTS/DFS on nv0x, Render on newer cards)
 * geode (GX and LX variants, Copy/Solid/Composite) - [[http://cgit.freedesktop.org/xorg/driver/xf86-video-geode/tree/README|README]], [[ http://cgit.freedesktop.org/xorg/driver/xf86-video-geode/tree/src|code]]

Work in progress:

 * [[http://c133.org/tmp/tdfx_exa.patch|tdfx]]
 * [[http://git.sh0n.net/|s3virge]] (Copy only currently) <-- link died ?
 * [[http://www.botchco.com/alex/2006soc/|r128]] Joseph Garvin SoC

No work started, but capable of Render acceleration:

 * glide
 * glint (supported in KAA), Coming soon (ShawnStarr)
 * i740
 * imstt
 * newport
 * impact
 * rendition
 * trident (supported in KAA)
 * voodoo

No work started, some chips might be capable of Render acceleration:

 * apm (via the voodoo rush)
 * cirrus (laguna?)
 * neomagic (256XL+ was the only one with a 3D engine) (supported in KAA)
 * cyrix/nsc (new GX2s have an alpha combiner)
 * sun{ffb,leo}

No work started, no Render acceleration possible:

 * ark
 * chips (supported in KAA)
 * s3 (supported in KAA)
 * sun{bw2,cg14,cg3,cg6,tcx} (tcx has some EXA support in NetBSD tree: [[ http://cvsweb.netbsd.org/bsdweb.cgi/xsrc/external/mit/xf86-video-suntcx/dist/src/?only_with_tag=MAIN | WebCVS Link]])
 * tga
 * tseng

Probably unsuitable for EXA support:

 * dummy
 * fbdev
 * vesa
 * vga
 * vmware
 * wsfb
