[SOLVED]NV18: nouveau_dri.so is opened instead of nouveau_vieux_dri.so

intelfx · 2014-04-08 11:28:55

Hi,

I'm having trouble getting nouveau hardware acceleration work on an NV18 [10de:0185] board.
The board is:

02:00.0 VGA compatible controller: NVIDIA Corporation NV18 [GeForce4 MX 4000] (rev a4)

Running glxgears produces this output (with LIBGL_DEBUG=verbose):

libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 4: 10de:0185, driver nouveau
libGL: OpenDriver: trying /usr/lib/xorg/modules/dri/tls/nouveau_dri.so
libGL: OpenDriver: trying /usr/lib/xorg/modules/dri/nouveau_dri.so
libGL: driver does not expose __driDriverGetExtensions_nouveau(): /usr/lib/xorg/modules/dri/nouveau_dri.so: undefined symbol: __driDriverGetExtensions_nouveau
libGL error: failed to create dri screen
libGL error: failed to load driver: nouveau

Here I can see that libGL tries to use nouveau_dri.so (post-NV20) while I have NV18 and thus need nouveau_vieux_dri.so.

Symlinking nouveau_dri.so to nouveau_vieux_dri.so fails:

libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 4: 10de:0185, driver nouveau
libGL: OpenDriver: trying /usr/lib/xorg/modules/dri/tls/nouveau_dri.so

How can I make libGL look for the correct driver?

Thanks.

That's an old card and may offer very little HW acceleration .

See http://nouveau.freedesktop.org/wiki/MesaDrivers

nouveau_vieux (NV04 - NV20)
nouveau_vieux_dri.so is a classic Mesa DRI driver, and not a Gallium3D driver, because these cards do not have enough shader capabilities to reasonably support the Gallium3D infrastructure.
Do not file bug reports about this driver.

Your best best might very well be to remove nouveau-dri and see what performance you get using mesa llvmpipe software acceleration.

I know, yes.

I'm already on llvmpipe, libGL falls back to it automatically, but the CPU is 1100 MHz Athlon XP. The question is specifically about enabling HW acceleration in order to offload as much as possible.

Intelfx, i'm sorry for assuming you hadn't seen that.

My post was intended to indicate this is likely a problem that can only be solved upstream , and upstream doesn't want to deal with bugs for the nouveau_vieux driver.

for figuring out HW acceleration issues, glxinfo is often more useful then glxgears.
please post the output of glxinfo (you might need to use LIBGL_DEBUG=verbose also) .

If that gives similar result as glxgears :

- You could try posting to mesa-users mailing list , http://mesa3d.org/lists.html , to see if there are people willing to help.
- aur has the proprietary nvidia-96xx package that supports your card, it may give you better performance then nouveau.

So it got "magically" resolved after a recent mesa update. BTW, hardware acceleration increased glxgears FPS from ~35 to ~273 and glxspheres FPS (full-screen) from <1 to ~35. I guess, HW acceleration actually makes a difference.
