     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.
