- AMD Geode GX and LX graphics driver for X.Org
- =============================================
- Last updated: 2008-08-13
-
- = Introduction =
-
- This is the X graphics driver for the AMD Geode GX and LX processors.
- The GX driver features XAA and EXA support for graphics acceleration,
- and the LX driver supports EXA (including compositing). Both drivers
- support dynamic rotation with XRandR, and Xv overlay support.

-
- = Roadmap =
-
- Support for X servers older than 1.4 is expected to be dropped in the
- near future. If your distribution still hasn't upgraded, please urge
- them to get around it soon.
-
- Support for old GX1 Geodes by Cyrix and NSC will be reintroduced soon,
- at which point xf86-video-cyrix and xf86-video-nsc will be retired.
-
- = Dependencies =
-
- As of version 2.9.0, this driver depends on X.Org server 1.3 or newer,
- because it utilizes the new common DDC probing libraries from X.Org.
-
- If necessary, it might be possible to create autoconf macros to make
- this driver compile against older X servers, following this example:
-
- http://lists.freedesktop.org/archives/xorg-commit/2007-February/010341.html
-
- Patches accomplishing the same trick for the Geode driver are welcome.
-
- = Configuration options =
-
- You can specify the Geode driver in the normal fashion:
-
- Section "Device"
- Identifier "AMD Geode"
- Driver "geode"
- Option "blah" "blah"
- ...
- EndSection
-
- The following options may be added to the section:
-
- == GX ==
-
- SWCursor: Enable software cursors (essentially disabling HW cursor support)
- NoCompression: Disable video bandwidth compression
- NoAccel: Disable hardware assisted acceleration
- AccelMethod: "EXA" (default) or "XAA"
- Rotate: Select a orientation to start with - LEFT, INVERT, CCW
- NoPanel: Disable panel support
- OSMImageBuffers: Set the number of image buffers (XAA only)
- OSMColorExpBuffers: Set the number of color expansion buffers (XAA only)
- FBSize: Specify the size of the video space (in bytes)
- PanelGeometry: Specify the geometry of the attached panel ("<width>x<height>")
-
- == LX ==
-
- SWCursor: Enable software cursors (essentially disabling HW cursor support)
- NoCompression: Disable video bandwidth compression
- NoAccel: Disable hardware assisted acceleration
- Rotate: Select a orientation to start with - LEFT, INVERT, CCW
- NoPanel: Disable panel support
- ExaScratch: Specify the amount of extra EXA scratch buffer (in bytes)
- FBSize: Specify the size of the video space (in bytes)
- PanelGeometry: Specify the geometry of the attached panel ("<width>x<height>")
