Summary: R6xx kms gloss corruption.
Product: DRI
Version: XOrg CVS
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: li...@andyfurniss.entadsl.com
RV670 AGP card running gits drm-next,ddx and mesa.
Repeated running of the mesa demo gloss sometimes produces rendering errors as
attached. The corruption is always the same. How many runs is quite variable.
Corruption happens with kms agp and pcie gart.
I haven't managed to produce in ums or sw, but because it may take many runs
and possibly a bit of browsing in between I can't be 100% sure it's just kms.
Reseting mesa git to 5e77b61e393144e76fe0a280c3c5da2d36703bbb makes the
likelyhood of corruption very small (I also notice I get 320fps vs 960fps with
master).
Due to the time taken to reproduce it's going to be quite hard to find a guilty
commit easily, though over time, if I have time I'll try.
Perhaps someone with a PCIE card could try to reproduce - it seems easier with
current master to trigger it.
