           Summary: [r600g, tiling] visual errors and GPU resets
           Product: DRI
           Version: DRI CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: liquid.acid@gmx.net


Hello!

Yesterday I saw with much delight that the was some new tiling code in r600g,
which could be enabled with a simple envvar. So I pulled drm-radeon-testing and
applied Dave's patch for the CS checker to it (this one:
http://article.gmane.org/gmane.comp.video.dri.devel/51060).

However I encountered several problems with the new code (exporting
R600_FORCE_TILING=1 makes a difference, so it is working to some extent:

1) ioquake3 shows lots of gfx errors. Mipmaps are affected the most (when
setting r_textureMode to GL_LINEAR these problems disappear), but also small
textures seem to be affected (staircases, which use small textures, are either
rendered totally black or black with white stripes).

2) doom3 (demo) shows similar mipmap-related errors.

3) ut2004 is completly unplayable, I get GPU resets nearly every frame and most
of the geometry is missing.

4) ut2003 kinda works, but the HUD is messed up and sprite rendering is totally
broken

Going to post some snips from the kernel log later.

My hardware:
01:00.0 VGA compatible controller: 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.

Greets,
Tobias

Needless to say, but I didn't see _any_ performance increase with
R600_FORCE_TILING enabled. Isn't this supposed to bump the fps a lot?

I didn't get a chance to test on r700 yet, there may be some more bits I need
to look at, I haven't noticed a large FPS difference on my GPUs either, which
is sad, but I've got a bit of work to do yet, I actually added tiling to help
with s3tc rather than for the FPS boost.

btw you may also need some patches from Alex to fix the group size and any
other CS checkers patch that popped up lately.

You mean these ones?
http://article.gmane.org/gmane.comp.video.dri.devel/50968
http://article.gmane.org/gmane.comp.video.dri.devel/50966

Concerning s3tc, how exactly does tiling interact with that?

OK, so I just found some time to retest the issues.

Again mesa, libdrm and xf86-video-ati are git master. I'm also using drm-next
(not drm-r-t) this time, since it looks like it's more up to date.

However with this config mipmapping seems to be broken in all configs. I have
mipmap render errors (which disappear in quake-engine based games when setting
gl_texturemode to either GL_NEAREST or GL_LINEAR) with r600 classic and
gallium, doesn't matter what I choose.

R600_FORCE_TILING introduced even more errors, so I switched it off again right
away. But the problems with mipmaps stay.

Now tracking the new issue in bug #31400. I'm going to return to this bug when
mipmaps are working again on mesa classic.

I'm currently on vacation, so I can't test this at the moment. Will do a check
when I return home.

I have retested this with all important components updated:
Issue is no longer present for me. Forcing tiling on doesn't create any (more)
major issues on quake3, doom3 and ut then without this option.

Setting this to RESOLVED, FIXED.

After doing some thorough testing today with ut2004 I noticed that mipmaps are
still affected when having R600_FORCE_TILING enabled. Going to take some
screenshots later. I didn't encounter any GPU resets though, so it's just
rendering errors and it seems to be limited to mipmaps.

I'm closing this one, since the main issue has changed. Also recent tests show
that fewer applications are affected.
