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@lists.freedesktop.org ReportedBy: lists@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.
