Summary: [r600g] tiling breaks rendering Product: DRI Version: XOrg 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.acid@gmx.net
Hi there,
just recently the tiling patches for r6xx went into git master. I noticed that r600c works fine with these, but r600g breaks with ColorTiling enabled. To get correct visuals out of the gallium driver I have to disable tiling first, then it works again.
Seems like r600g misinterprets the tiling state of the framebuffer. The visuals are similar to the ones you got when patching mesa with the tiling patchset, but forgetting to do the same for the ddx.
