13 1.1 mrg
14 1.1 mrg = Introduction =
15 1.1 mrg
16 1.1 mrg This is the X graphics driver for the AMD Geode GX and LX processors.
17 1.1 mrg The GX driver features XAA and EXA support for graphics acceleration,
18 1.1 mrg and the LX driver supports EXA (including compositing). Both drivers
19 1.1 mrg support dynamic rotation with XRandR, and Xv overlay support.
20 1.1 mrg
21 1.1 mrg = Roadmap =
22 1.1 mrg
23 1.1 mrg Support for X servers older than 1.4 is expected to be dropped in the
24 1.1 mrg near future. If your distribution still hasn't upgraded, please urge
25 1.1 mrg them to get around it soon.
26 1.1 mrg
27 1.1 mrg Support for old GX1 Geodes by Cyrix and NSC will be reintroduced soon,
28 1.1 mrg at which point xf86-video-cyrix and xf86-video-nsc will be retired.
29 1.1 mrg
30 1.1 mrg Until then, the current situation for Geode coverage is as follow:
31 1.1 mrg
32 1.1 mrg xf86-video-geode
33 1.1 mrg * Geode LX (a.k.a. GX3) PCI ID 0x1022:0x2081
34 1.1 mrg * Geode GX (a.k.a. GX2) PCI ID 0x100B:0x0030 (rebranded GX2)
35 1.1 mrg
36 1.1 mrg xf86-video-nsc
37 1.1 mrg * Geode GX2 (a.k.a. GX2) PCI ID 0x100B:0x0030 (a.k.a. "Red Cloud")
38 1.1 mrg * Geode SCx200 (a.k.a. GX1) PCI ID 0x100B:0x0504
39 1.1 mrg * Geode SC1400 (a.k.a. GX1) PCI ID 0x100B:0x0104
40 1.1 mrg
41 1.1 mrg xf86-video-cyrix
42 1.1 mrg * Geode MediaGX (a.k.a. GX1) PCI ID 0x1078:0x0104
43 1.1 mrg
44 1.1 mrg Please note that both NSC and GEODE support GX2. This is indeed correct.
45 1.1 mrg However, only GEODE has up-to-date code, while NSC is deprecated.
46 1.1 mrg
47 1.1 mrg = Dependencies =
48 1.1 mrg
49 1.1 mrg As of version 2.11.4, this driver depends upon X server 1.5 or newer,
50 1.1 mrg because the GX Randr code utilizes dixSetPrivate whose API was modified
51 1.1 mrg in a non backward-compatible way.
52 1.1 mrg
53 1.1 mrg #ifdef'ing the changes from f1268f3ba8404129d358db3bb1e66f3841f7018a
54 1.1 mrg and b28abde0276ddd7f687242f3886f98b0e49a7fc2 might make it possible
55 1.1 mrg to build this driver against older X servers. Patches are welcome.
56 1.1 mrg
57 1.1 mrg As of version 2.9.0, this driver depends on X server 1.3 or newer,
58 1.1 mrg because it utilizes the new common DDC probing libraries from X.Org.
59 1.1 mrg
60 1.1 mrg If necessary, it might be possible to create autoconf macros to make
61 1.1 mrg this driver compile against older X servers, following this example:
62 1.1 mrg
63 1.1 mrg http://lists.freedesktop.org/archives/xorg-commit/2007-February/010341.html
64 1.1 mrg
65 1.1 mrg Patches accomplishing the same trick for the Geode driver are welcome.
66 1.1 mrg
67 1.1 mrg = FAQ =
68 1.1 mrg
69 1.1 mrg Q: Why doesn't this GEODE driver work at WXGA (wide screen) resolutions?
70 1.1 mrg
71 1.1 mrg A: Make sure that TFT Panel support is disabled in the BIOS settings,
72 1.1 mrg otherwise resolutions will be restricted to traditional VGA modes.
73 1.1 mrg The GEODE offers a choice between CRT-only, CRT+TFT, TFT-only for
74 1.1 mrg output device and selecting CRT-only removes the VGA restriction.
75 1.1 mrg
76 1.1 mrg Q: How do I produce useful information whenever submiting a bug report?
77 1.1 mrg
78 1.1 mrg A: See http://www.x.org/wiki/Development/Documentation/ServerDebugging
79 1.1 mrg and follow the instructions.
80 1.1 mrg
81 1.1 mrg Q: How do I test development snapshots from the upstream GIT repository?
82 1.1 mrg
83 1.1 mrg A: Run the following commands from a command line interpreter shell...
84 1.1 mrg 1. git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-geode
85 1.1 mrg 2. Debian/Ubuntu: apt-get install autoconf automake libtool xutils-dev
