           Summary: rv670 + tiling patches + tiling enabled = parse errors
                    on some demos.
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: lists at andyfurniss.entadsl.com


Running drt + patch that fixes
https://bugs.freedesktop.org/show_bug.cgi?id=28327.

Patched Mesa and ddx for tiling and did some testing - I can't reproduce

https://bugs.freedesktop.org/show_bug.cgi?id=28342

but if I enable tiling in xorg.conf I get parse errors with some demos, but not
others.

eg [glx]gears will quit with drmRadeonCmdBuffer: -22. Kernel failed to parse or
rejected command stream, dmesg =

radeon 0000:02:00.0: r600_cs_track_validate_cb:216 cb height (306) invalid
radeon 0000:02:00.0: r600_packet3_check:1245 invalid cmd stream 520
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

Other demos eg gloss, cubemap shadowtex also fail 
but others work OK eg.
morph3d, tunnel, geartrain, openarena, nexuiz and mplayer -vo gl.

I tried the ddx patch that fixes the cold boot bug above, but it doesn't help.
