Description Matyas Csanyi 2014-01-20 22:33:06 UTC

Hi,

this is my first bug report, so feel free to point me in a different direction if necessary please. I am getting a flawless 30+ fps on one of the tutorial maps without any graphical glitch. However on a different map, there are heavy texture issues. Please see: http://youtu.be/wHLVaa5aTmA 

Last few lines from dmesg after gameplay:

[ 3375.201258] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !

I am happy to do additional digging if someone points me in some direction.

Comment 2 Alex Deucher 2014-02-07 19:48:54 UTC

Possibly related to bug 68451.

Comment 3 Matyas Csanyi 2014-02-07 20:39:02 UTC

I tried running Dota2 with
R600_DEBUG=noinvalrange %command% -console
R600_DEBUG=noinvalrange,nodma,nocpdma %command% -console
R600_DEBUG=nodma,nocpdma %command% -console

...neither helps. I don't understand why 68451 has been marked as fixed though. I'll retry this weekend with 3.14rc2, unless someone advises on what next to try out.

Comment 4 Matyas Csanyi 2014-02-08 00:17:40 UTC

I've compiled the latest kernel from GIT (3.14), and the texture corruption is gone.

See comment 48 in bug 68451 for an explanation about why it was marked as fixed. In short, the original bug (identified problematic commit on given hardware) has been fixed. The other reports must be treated as different bugs.
