Can you explain the broken behavior or do you have a screen shot? Or even better, do you have a simple test case that shows the broken behavior? The basic npot demos work fine. I suspect the actual bug may lie elsewhere; i.e., there are bugs with certain types of vertex fetches. Created attachment 33257 [details]
NP2 Workaround Enabled
Screenshot taken from 3Dmark2001SE running under WINE with the NP2 workaround employed.

NP2 Workaround Disabled
Screenshot from 3DMark2001SE running on WINE with the NP2 quirk disabled.
In the screenshots you will see that when the workaround is disabled, the human models are missing. When the workaround is enabled, the models are shown. Does it work any better with mesa from git master or 7.7 branch? Specifically this commit might help: eeb49d3ad82861272e8987515df3cc5da4ed2d09 @Alex My entire toolchain is from current git. (wine,linux,drm,mesa,xf86-video-ati) HD4870, Ubuntu-9.10 x86_64 3DMark2001SE is free software and available for download from: http://www.futuremark.com/download/3dmark2001/ WINE is also free software and available from: git://source.winehq.org/git/wine.git (In reply to comment #6) > @Alex > > My entire toolchain is from current git.

The last commit for mesa i have is, 3a916b0e81cdbc695d0af317f7d5d8515af13c02 (In reply to comment #9) > The last commit for mesa i have is, 3a916b0e81cdbc695d0af317f7d5d8515af13c02 > Ok, so it's another issue then. This is in the shared code. I see this bug with r200 too. Models have worked before rewrite so this is some regression in rewrite. > --- Comment #10 from Alex Deucher <agd5f@yahoo.com> 2010-02-12 11:27:49 PST --- > (In reply to comment #9) >> The last commit for mesa i have is, 3a916b0e81cdbc695d0af317f7d5d8515af13c02 >> > > Ok, so it's another issue then. Note: classic r600 driver has been abandoned. Please use r600g (gallium driver) instead. Is this still an issue with a newer driver/kernel? It seems to be resolved. I just reloaded 3Dmark2001SE and ran it under Ubuntu 12.04 with current gallium drivers and wine and couldn't reproduce the issue. |
