Hi,

there is a bug that prevents to run 3D applications under wine with the
nouveau vieux driver. It fails with this error message:

err:d3d:wined3d_adapter_init_gl_caps >>>>>>>>>>>>>>>>> GL_INVALID_ENUM
(0x500) from extension detection @ ../../../dlls/wined3d/directx.c /
2720
fixme:d3d_caps:wined3d_guess_card_vendor Received unrecognized
GL_VENDOR "Nouveau". Returning HW_VENDOR_NVIDIA.
fixme:d3d_caps:select_card_nvidia_mesa Unknown renderer "Mesa DRI nv11
x86/MMX+/3DNow!+".
nv10_state_fb.c:50: get_rt_format: Assertion `0' failed.
wine: Assertion failed at address 0xb77d8424 (thread 0009), starting
debugger...


The installed drivers are:

libdrm-nouveau1a 2.4.33-3 i386
libgl1-mesa-dri 8.0.5-3 i386
libgl1-mesa-glx 8.0.5-3 i386
linux-image-3.2.0-4-686-pae 3.2.35-2 i386
xserver-xorg-video-nouveau 1:1.0.1-4 i386

The video card is:

NVIDIA Corporation NV11 [GeForce2 MX/MX 400] (rev a1)


It runs fine without the hardware acceleration, removing the user from
the group video that owns /dev/dri/card0


This bug seems to be fixed in wine 1.5.0 with this commit:

http://source.winehq.org/git/wine.git/blobdiff/ab4474c19b308311b6408a2802225a44849bb70c..112e2e219f88cf81280359ae74ae809a3d288574:/dlls/wined3d/directx.c


At a first look this patch should apply nicely to the 1.4.1 version.

I think this patch should be added to wheezy because the actual code is
broken, as it checks NV04-NV20 with the Gallium renderer, that never
supported these cards, that instead are handled by the vieux driver
present in wheezy. Also these are minor changes to the device detection
between wine and opengl.


Ciao

severity 697913 important
thank you

* Trek:

I assume that many of our users will want to run 3D applications on such
a setup, therefore setting the severity as important. I think this
should be fixed for wheezy if possible.

Could you build the wine package from source, with this patch applied,
and report if it fixes the problem for you?

(If you have trouble building the package from source, I can build them
for you.)

Cheers,

is not resolved. I have done more testing and I found that I
misunderstood code and error messages.


SimpleGLUT demo runs fine with and without the patch!
http://web.media.mit.edu/~gordonw/OpenGL/simpleGLUT.zip

It actually use hardware acceleration (90fps vs 3fps on software render)


Critter fails with and without the patch, but not with software renderer
http://prdownloads.sourceforge.net/criticalmass/CriticalMass-Windows-1.0.0.zip

I have attached the full dump of patched and unpatched version.

The function wined3d_guess_card_vendor returns anyway HW_VENDOR_NVIDIA
even if not correctly recognized. The function select_card_nvidia_mesa
has a fallback to discover the card by gl_info. So the patch I proposed
may be useful but not required.

The error messages "Received unrecognized GL_VENDOR" and "Unknown
renderer" appear only when launching Critter and not with Simpleglut.


Running critter the common error with and without the patch is:
nv10_state_fb.c:50: get_rt_format: Assertion `0' failed.

that should not be an error of wine, but of nouveaux driver.


So, I'm really sorry to have misreported the bug to wine and to have you
work on this.


I think the bug should be reassigned to the libgl1-mesa-dri package.

I found similar bug reports with other old GForce < NV30:

Ciao!

reassign -1 src:mesa
thanks

Thanks for the info.  Reassigning to the mesa package, which contains
the above code.

Best wishes,
Mike
