[Nouveau] Hacking 3D on the NV17

[Phillip Ezolt]

Hi,
   I recently got access to an old NV17 card (my wife's old laptop) ,
and I would like to start hacking.

I grabbed the 1/20/08 fedora DRM + nouveau driver packages from
hughsie's fedora repo.
http://people.freedesktop.org/~hughsient/fedora/8/i386/
(Shame on me, I didn't build from git)

I installed mesa with:  'git clone
git://anongit.freedesktop.org/git/mesa/mesa', and compiled
with "make linux-dri-x86 DRI_DIRS=nouveau"

However, when I try to run any glx apps, with the appropriate LD paths
set, I get
"nouveau DRI driver expected DDX version 1-1.2.x but got version 2.1.6"

This agrees with my xorg.log:
"
(II) LoadModule: "nouveau"
(II) Loading /usr/lib/xorg/modules//drivers/nouveau_drv.so
(II) Module nouveau: vendor="X.Org Foundation"
        compiled for 1.3.0, module version = 2.1.6
        Module class: X.Org Video Driver
        ABI class: X.Org Video Driver, version 1.2
"

The DDX expected value is hard coded in:
nouveau_screen.c:
...
__GLcontextModes *__driDriverInitScreen(__DRIscreenPrivate *psp)
{
        static const __DRIversion ddx_expected = { 1, 2, 0 };
...

Example:

"
[root at localhost lib]# export LD_LIBRARY_PATH=/home/ezolt/nouveau/mesa/lib/
[root at localhost lib]# export LIBGL_DRIVERS_PATH=/home/ezolt/nouveau/mesa/lib/
[root at localhost lib]# env DISPLAY=:0 glxinfo
name of display: :0.0
nouveau DRI driver expected DDX version 1-1.2.x but got version 2.1.6
libGL warning: 3D driver returned no fbconfigs.
libGL warning: 3D driver returned no fbconfigs.
libGL error: InitDriver failed
libGL error: reverting to (slow) indirect rendering
glxinfo: xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) -
(dpy->request)) >= 0)' failed.
Aborted
"

What am I doing wrong?

Cheers,
