Needless to say, but I didn't see _any_ performance increase with R600_FORCE_TILING enabled. Isn't this supposed to bump the fps a lot? I didn't get a chance to test on r700 yet, there may be some more bits I need to look at, I haven't noticed a large FPS difference on my GPUs either, which is sad, but I've got a bit of work to do yet, I actually added tiling to help with s3tc rather than for the FPS boost. btw you may also need some patches from Alex to fix the group size and any other CS checkers patch that popped up lately. You mean these ones? http://article.gmane.org/gmane.comp.video.dri.devel/50968 http://article.gmane.org/gmane.comp.video.dri.devel/50966 Concerning s3tc, how exactly does tiling interact with that? OK, so I just found some time to retest the issues. Again mesa, libdrm and xf86-video-ati are git master. I'm also using drm-next (not drm-r-t) this time, since it looks like it's more up to date. However with this config mipmapping seems to be broken in all configs. I have mipmap render errors (which disappear in quake-engine based games when setting gl_texturemode to either GL_NEAREST or GL_LINEAR) with r600 classic and gallium, doesn't matter what I choose. R600_FORCE_TILING introduced even more errors, so I switched it off again right away. But the problems with mipmaps stay. Now tracking the new issue in bug #31400. I'm going to return to this bug when mipmaps are working again on mesa classic. Do you still have this issue with lastest mesa git & recent kernel+ddx I'm currently on vacation, so I can't test this at the moment. Will do a check when I return home. I have retested this with all important components updated: Issue is no longer present for me. Forcing tiling on doesn't create any (more) major issues on quake3, doom3 and ut then without this option. Setting this to RESOLVED, FIXED. After doing some thorough testing today with ut2004 I noticed that mipmaps are still affected when having R600_FORCE_TILING enabled. Going to take some screenshots later. I didn't encounter any GPU resets though, so it's just rendering errors and it seems to be limited to mipmaps. Created attachment 42552 [details]

I'm closing this one, since the main issue has changed. Also recent tests show that fewer applications are affected. |
