Some time ago I removed the emission of the regs in classic and it didn't really add any regressions. Please try this: Change src/gallium/drivers/r300/r300_state_invariant.c:134 to: OUT_CS_REG(R300_SC_CLIP_RULE, 0); and please let me know if it helps. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

http://bugs.freedesktop.org/show_bug.cgi?id=27339 --- Comment #2 from Mathias Fröhlich mathias.froehl...@web.de 2010-03-27 08:07:58 PST --- (In reply to comment #1) I think the classic driver shouldn't set those regs on KMS. Some time ago I removed the emission of the regs in classic and it didn't really add any regressions. Hmm, looking again deeper into the code I just observed that r300 used R300_CLIPRECT* to do scissor clipping to viewport boundaries whereas r300g uses R300_SCISSOR*. Please try this: Change src/gallium/drivers/r300/r300_state_invariant.c:134 to: OUT_CS_REG(R300_SC_CLIP_RULE, 0); and please let me know if it helps. I have reverted to master and applied that change but: That does not help. With that change the whole window is not painted at all - you just see stale buffer content. I believe that this value is some kind of bitmask to tell the card which side of the R300_CLIPRECT* coordinate to clip away. It appeared to me that you can not easily switch those off, rather than just 'clip the other side'. ... not looked into the documentation. Don't know if r300 should or should not use these registers, but it seems to me that r300 just still uses them as well as the kms kernel lets r300 classic set those registers. So altogether It would be good to have something that helps testing r300g as an alternative to r300 classic in an easy way.

http://bugs.freedesktop.org/show_bug.cgi?id=27339 --- Comment #4 from Nicolai Hähnle nhaeh...@gmail.com 2010-03-27 14:19:18 PST --- Clipping works like this: You have four cliprects. Each pixel is compared to all of them. The pass/fail result gives you a bitmask which is interpreted as a number N between 0 and 15 (inclusive). Then you look at the N-th bit of the clip rule register. If it is 1, continue, if it is 0, discard the pixel. Therefore, you need to set the clip rule register to 0x to disable this clipping functionality. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
