           Summary: [r600g, tiling] mipmap rendering errors / block
                    artifacts
           Product: DRI
           Version: DRI 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,

this is a update of bug #31046, where the main issue was GPU resets caused by
enabling tiling (R600_FORCE_TILING=1) with the r600g driver.

The situation however was changed, and now R600_FORCE_TILING only causes mipmap
rendering errors in a few application. Last time I tested ioquake3, doom3
(demo) and both ut2003 and ut2004.

ut03 and ut04 are still affected by the blocky rendering errors (see the other
bug for screenshots illustrating the problem), but both ioquake3 and doom3 now
look perfectly fine.

My hardware:
ATI Technologies Inc Radeon HD 4770 [RV740]

libdrm, mesa and xf86-video-ati are all git master tip.
ColorTiling is enabled in the xorg.conf, verified this by checking the Xorg
logfile.
kernel is d-r-t

Greets,
Tobias

Can no longer reproduce this issue. So it looks fixed.

It's still there. Tiling is just disabled by default and the environment
variable changed to R600_TILING. Just try the piglit test
fbo-generatemipmap-formats with: R600_TILING=on
piglit/bin/fbo-generatemipmap-formats and switch to NPOT textures with 'd' and
go through various test sets ('n'). Some of them are still rendered wrong.

Yeah, you're right -- I completly forgot that the envvar changed :(

Retested with the correct envvar and I still can't reproduce the artifacts.
They don't appear anymore in ut2003 and ut2004, which were the only remaining
games on my list.

Leaving this open, since Droste still seems to have issues (I didn't check
these tests).

Could you test nexuiz (just to check that it's not my fault in some way)? It
should be visible there too. I can't test ut2k3/2k4.

No, also no errors visible there. Which kernel do you use? Using the drm-next
branch here.

Currently I'm running drm-fixes (built ~1h ago). Most probably it's only
visible on some cards (evergreen/juniper here).

(libdrm, mesa and ddx were also updated to current git master ~1h ago)

I'm closing this one then, since it was primarly about the R700 series and the
artifacts I experienced in games using the ut engine.
