https://bugs.freedesktop.org/show_bug.cgi?id=31046 Summary: [r600g, tiling] visual errors and GPU resets Product: DRI Version: DRI CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: liquid.acid@xxxxxxx Hello! Yesterday I saw with much delight that the was some new tiling code in r600g, which could be enabled with a simple envvar. So I pulled drm-radeon-testing and applied Dave's patch for the CS checker to it (this one: http://article.gmane.org/gmane.comp.video.dri.devel/51060). However I encountered several problems with the new code (exporting R600_FORCE_TILING=1 makes a difference, so it is working to some extent: 1) ioquake3 shows lots of gfx errors. Mipmaps are affected the most (when setting r_textureMode to GL_LINEAR these problems disappear), but also small textures seem to be affected (staircases, which use small textures, are either rendered totally black or black with white stripes). 2) doom3 (demo) shows similar mipmap-related errors. 3) ut2004 is completly unplayable, I get GPU resets nearly every frame and most of the geometry is missing. 4) ut2003 kinda works, but the HUD is messed up and sprite rendering is totally broken Going to post some snips from the kernel log later. My hardware: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 4770 [RV740] libdrm, mesa and xf86-video-ati are all git master tip. ColorTiling is enabled in the xorg.conf, verified this by checking the Xorg logfile.
