# Geode Driver
## 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 [[Ubuntu BTS|https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/423866]] 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 [[X.org BTS|https://bugs.freedesktop.org/show_bug.cgi?id=15700]]
* [[AutoConfig|AutoConfig]] only implemented for LX.
* With X server 1.3 and X server 1.4:
* Some platforms will freeze when using _X -configure_: [[Ubuntu BTS|https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amd/+bug/140051]].
* 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: [[Debian BTS|http://bugs.debian.org/451089]] [[Ubuntu BTS|https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amd/+bug/180742]].
* 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: [[!format txt """
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 [[Intel driver autoconf|http://lists.freedesktop.org/archives/xorg-commit/2007-February/010341.html]] methods.
