Summary: [r600g, tiling] mipmap rendering errors / block
artifacts
Product: DRI
Version: DRI CVS
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: liquid.a...@gmx.net
Hi there,
this is a update of bug #31046, where the main issue was GPU resets caused by
enabling tiling (R600_FORCE_TILING=1) with the r600g driver.
The situation however was changed, and now R600_FORCE_TILING only causes mipmap
rendering errors in a few application. Last time I tested ioquake3, doom3
(demo) and both ut2003 and ut2004.
ut03 and ut04 are still affected by the blocky rendering errors (see the other
bug for screenshots illustrating the problem), but both ioquake3 and doom3 now
look perfectly fine.
My hardware:
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.
kernel is d-r-t
Greets,
Tobias
