Summary: [r600g] Evergreen vertex shaders transform vertices incorrectly in wine programs Product: Mesa Version: git Platform: All OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: rubenf3000@gmail.com

All the wine applications and games using vertex shaders that I've tried in evergreen position the vertices incorrectly.

All of them render correctly using llvmpipe and an r300g card/driver.

Graphics Card: ATI Technologies Inc Juniper [Radeon HD 5750 Series] CPU: Intel Core Duo 1.8 Ghz, 2.5 GB RAM Linux kernel 2.6.37, libdrm 2.4.23 Latest Mesa git

Games tested: Call of Cthulhu: Dark Corners of the Earth Portal Sam & Max Season One Tales of Monkey Island Back to the Future: The Game

I'll post logs and screenshots for Tales of Monkey Island

Using Tom Stellard's branch (in the hopes it produces more useful debugging output):

git://anongit.freedesktop.org/~tstellar/mesa

we get a screenshot that renders correctly the inanimate objects, but the characters are not rendered at all

...

This may be similar to bug 31667, does https://bugs.freedesktop.org/attachment.cgi?id=42992 make it any better?

Your patch makes the errors go away in three of the five games I tested for the error: Call of Cthulhu, Sam & Max, and Back to the Future.

Portal seems to be unaffected, and Tales of Monkey Island continues to transform the vertices incorrectly, yet in a different way than before; I'll attach a new screenshot and log for the latter.

So yes, I agree this is, at least in part, the same bug as 31667.

--- Comment #12 from Rubén Fernández rubenf3000@gmail.com 2011-04-04 22:34:56 PDT --- This bug is gone with the latest version of mesa git; it seems it was commit df3d11f6cab5dd5b4ff3cb0f10c8fe3e5954a16d "FLT_TO_INT_FLOOR and FLT_TO_INT_RPI are vector-only instructions on Evergreen" that did the trick.

Also, the commits:

244a3bbf14ef4f739e7f3be298c8613a2667fce0 "Handle texture fetch instructions with relative addressing", da5b4764b28a1efd2e9dbf0741247288da36f546 "Handle texture fetch instructions with neg or abs on source register", and 78037d95da06b81799e75410154c8141b0a30ec0 "Handle texture fetch instructions with swizzle on source register",

fixed texture addressing problems in those same games (that went unnoticed due to the geometry misrendering)
