== Hardware Support ==
'''NOTE''': the '''cyrix''' and '''nsc''' drivers are seriously rotting and some distributions have chosen not to ship them. As such, we have set a milestone to import GX1 support into '''geode''' and then deprecate '''cyrix''' and '''nsc'''. Help is welcome! See below for details.

 * AMD Geode NX is not supported by any known driver.

=== xf86-video-geode ===
This driver was previously called '''amd'''. It was renamed '''geode''' to avoid confusion with ATI chipsets acquired by AMD.

 * AMD Geode LX (a.k.a. GX3) PCI ID: 0x1022:0x2081
 * AMD Geode GX (a.k.a. GX2) PCI ID: 0x100B:0x0030

This is not a typo; both '''nsc''' and '''geode''' support GX2. However, only '''geode''' has up-to-date code, while '''nsc''' is deprecated.

=== xf86-video-nsc ===
 * NSC Geode Media GX (a.k.a. GX2) PCI ID: 0x100B:0x0030
 * NSC Geode SCx200 (a.k.a. GX1) PCI ID: 0x100B:0x0504
 * NSC Geode SC1400 (a.k.a. GX1) PCI ID: 0x100B:0x0104

=== xf86-video-cyrix ===
 * Cyrix Geode Media GX (a.k.a. GX1) PCI ID: 0x1078:0x0104

=== AutoConfig support ===
 * LX  works since X server 1.5.
 * GX2 works since X server 1.7.
 * GX1 works since X server 1.7.

See patches on the [[https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/423866|Ubuntu BTS]] to implement this on 1.4 and 1.6; should also work on 1.3 and 1.5 with minor adjustments.

== Current Status: xf86-video-geode 2.11.14 (released: 2012-11-25) ==

=== Server-specific bugs ===
 * With X server 1.7 and up:
  * (no known issue)

 * With X server 1.5 and X server 1.6:
  * EXA Composite rendering bug: Black boxes [[https://bugs.freedesktop.org/show_bug.cgi?id=15700|X.org BTS]]
  * AutoConfig only implemented for LX.

 * With X server 1.3 and X server 1.4:
  * Some platforms will freeze when using ''X -configure'': [[https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amd/+bug/140051|Ubuntu BTS]].
   * Attachments include two patches against '''x86emu''' (port blacklist, PCI bus access) that resolve this issue.
    * ''blacklist patch rejected''
    * ''PCI patch merged into X core 1.5 tree''

 * With X server 1.2:
  * Cannot compile since 2.9.0 (see below).
  * Switching to a console using CTRL+ALT+Fx fails on some platforms: [[http://bugs.debian.org/451089|Debian BTS]] [[https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amd/+bug/180742|Ubuntu BTS]].
   * Attachments include a patch against '''x86emu''' (CPUID) that resolves the issue.
    * ''CPU ID patch merged into X core 1.5 tree''

 * With X server 1.1 and a static xorg.conf configuration file:
  * Cannot compile since 2.9.0 (see below).

=== Known Regression ===
 . Compilation against X server << 1.3 fails since '''geode''' 2.9.0 because of a missing header:
 {{{
 geode_ddc.c:31:23: error: xf86Modes.h: No such file or directory
 geode_ddc.c:158:50: error: missing binary operator before token "("
}}}
 Might be fixable following [[http://lists.freedesktop.org/archives/xorg-commit/2007-February/010341.html|Intel driver autoconf]] methods.
