           Summary: [r300g][glsl] Texture corruption in Xonotic with
                    lightmaps
           Product: Mesa
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: xeros@irc.pl

Screenshot of lightmaps corruption

Testing procedure:

1. Download Xonotic (Nexuiz fork) from
http://beta.xonotic.org/autobuild/Xonotic-20101017.zip (login: xonotic, pass:
g-23) (could be newer build, too)
2. Unzip and run ./xonotic-linux-glx.sh
3. Enable GLSL in video menu
4. Enable "Use lightmaps" in effects menu
5. Connect to any server.

Lightmaps do texture corruption in r300g as seen on screenshots. 
Textures are rendered properly for example on Nvidia binary driver on Nvidia
hardware.
My graphic card: ATI Radeon 9600 256MB AGP (RV350).

The problem has been discussed with Xonotic developers and does look like
driver bug.

The problem is not on every map but on most of them and not on every texture.
Example map red_V2: 
http://picpaste.com/xonotic000025-izMRie6h.jpg
The same at a bit closer distance:
http://picpaste.com/xonotic000026-JgQAIEys.jpg
More closer (on the left textures ok, doors and right textures broken):
http://picpaste.com/xonotic000027-j4riFPmN.jpg
Almost ok (this texture corruption gets random whenever I move the mouse):
http://picpaste.com/xonotic000028-ZEkd1DoG.jpg
Another map - evilspace2
(http://beta.xonotic.org/autobuild-bsp/evilspace-full-cb6860159bdfb02f5bd5d76ad78db7fdbeb2f1c3-310d495e18dccf5de69f7319f57176178d4d72ce.pk3):
http://picpaste.com/xonotic000033-QRBL0lWT.jpg - textures on the lower floor
are OK always.
The same map - showing one texture ok (it's always OK) and others broken: 
http://picpaste.com/xonotic000037-h1vhAD9q.jpg
Tried with suggested game option "r_shadow_deferred 1":
http://picpaste.com/xonotic000023-rNkR29Tq.jpg
Default map (glowplant) with lightmaps on glsl:
http://picpaste.com/xonotic000062-nOfZlVRw.jpg
The same place with lightmaps+deluxemapping:
http://picpaste.com/xonotic000063-WqFIFjDk.jpg
Once more red_V2 with lightmaps: 
http://picpaste.com/xonotic000066-ilX94A1H.jpg
The same place with lightmaps and "r_glsl_deluxemapping 1", too:
http://picpaste.com/xonotic000065-19VIO1a7.jpg
The same place with lightmaps, "r_glsl_deluxemapping 1" and "r_fakelight 2":
http://picpaste.com/xonotic000067-4VM3tJn9.jpg
Map that is working ok (evilspace remix) with both lightmaps and deluxemapping: 
http://picpaste.com/xonotic000060-gfu8U61e.jpg
Default map (glowplant) with "gl_picmip 1000":
http://picpaste.com/xonotic000071-eg1KFicn.jpg
The same after moving mouse a bit:
http://picpaste.com/xonotic000072-pIgPU6Sd.jpg
Like previous:
http://picpaste.com/xonotic000073-6NFQ7D9B.jpg
And one more:
http://picpaste.com/xonotic000074-5qEkk2A7.jpg
Glowplant map with default "mod_q3bsp_lightmapmergepower 4" option:
http://picpaste.com/xonotic000079-p7ku82CV.jpg
The same (not moved) with "mod_q3bsp_lightmapmergepower 3":
http://picpaste.com/xonotic000080-7p7PgQ2U.jpg
The same (not moved) with "mod_q3bsp_lightmapmergepower 2":
http://picpaste.com/xonotic000081-1mYDfeKo.jpg
The same (not moved) with "mod_q3bsp_lightmapmergepower 1":
http://picpaste.com/xonotic000084-xQuzetgC.jpg
The same (not moved) with "mod_q3bsp_lightmapmergepower 0":
http://picpaste.com/xonotic000082-AwGA2wtr.jpg - almost OK but with a big cost
of FPS drop and here a floor is still a problem but it's just like before -
random, not only the floor.

Does running with RADEON_DEBUG=noopt fix the problem?  If it does, can out post
the output of RADEON_DEBUG=vp,fp,noopt?  You can just post the stderr output, I
don't need any more screenshots.

I don't see any difference with RADEON_DEBUG=noopt for both lightmap and
lightmap+deluxemapping problem - both look like before.
And sorry for that many screenshots - I thought that making screenshots during
logs grab might help you to see what's the problem.

And I've tested it now with
libgl1-mesa-dri_7.10.0~git20101019+gallium.974fb466-0ubuntu0tormod_i386.deb +
the same version of glx and libglu packages from ubuntu xorg-edgers/radeon ppa,
too - no change comparing to previous builds.

It looks exactly like bug 28800 which we don't know how to fix.

Having said that, the corruption I observe with bug 28800 was much reduced by
upgrading my kernel from 2.6.34.x to 2.6.35.x. I haven't tried with 2.6.36.x
yet.

It's not *exactly* like bug 28800; I don't see anything like this in my dmesg
log:

[13255.216618] radeon 0000:01:00.0: object_init failed for (1048576,
0x00000006)
[13255.216631] [drm:radeon_gem_object_create] *ERROR* Failed to allocate GEM
object (1048576, 6, 4096, -12)

Also, I see from the glxinfo output that you have S3TC texturing enabled, which
presumably implies that you have the libtxc_dxtn.so library installed. So
assuming that Xonotic doesn't need S3TC texturing for anything, does
uninstalling this library affect the corruption in any way, please?

--- Comment #32 from Marek Olšák <maraeo@gmail.com> 2010-10-24 09:32:51 PDT ---
I have noticed the corruption happens under extreme memory pressure (e.g. ETQW
has corrupted textures with 64MB VRAM and the lowest graphics details, but if
you have 256MB VRAM, you may see the corruption with the highest details only),
so here is my theory.

In the kernel, there is function r100_copy_blit for copying buffers between RAM
and VRAM using the 2D engine, and it's hooked up in the TTM. The function is
used on r100 up to r500.

I believe switching between the 2D and 3D engine doesn't work as it should or
we don't flush some cache or something.

https://bugs.freedesktop.org/show_bug.cgi?id=30960

--- Comment #33 from Tomasz Czapiewski <xeros@irc.pl> 2010-10-24 13:08:36 PDT ---
Chris, yours suggestion was right!
I've installed libtxc_dxtn.so some time ago as some apps (games) could use it.
After removing this library the problem with rainbow colors/texture corruption
in my case was resolved. The other workaround is to enable option 'Avoid loosy
texture compression' in Xonotic menu which disables use of S3TC DDS textures.

And that what Marek has suggested about texture corruption with high detail it
was right, too but it didn't look like on those screenshots.
I've found this problem when I've run Xonotic with KDE KWin desktop effects
enabled and without libtxc_dxtn.so - not only the big FPS drop but there were
many different problems with textures (black textures, black and white
textures, black and white noise, screen smoothing with no textures, etc.).
Disabling KWin desktop effects + using lower quality textures + removing
libtxc_dxtn.so (so it disables GL_EXT_texture_compression_s3tc and GL_S3_s3tc
extensions) altogether does make the problem disappear.

And for texture formats that Xonotic needs - it uses JPG and TGA textures but
DDS compressed textures, too and I'd like to use them as I could use better
quality textures as I think it needs less RAM/VRAM(?) to handle them. And
better quality textures compressed as DDS does not make any FPS drop. And most
commercial games need S3TC.

So IMO, it does look like it's a duplicate of 28800.

Is there any chance to get this bug with libtxc_dxtn.so fixed to properly
handle DDS compressed textures?

I wonder why does S3TC with libtxc_dxtn.so in Xonotic works properly when
lightmaps are disabled? I can use better quality DDS textures (without KWin
desktop effects) just fine in Xonotic without lightmaps.

So, the problematic textures are dxt1_rgb and/or dxt1_rgba.

I've done some more testing and I've saw that when I have 60 FPS the problem is
gone with S3TC+lightmaps (all textures are OK, no matter what I'm looking at on
the map) but when the FPS gets dropped to 30 FPS the problem arrives or when
the problem arrives I get FPS drop to 30(?).

I wonder if the problem is with library or the S3TC handling by the driver
itself.
I wish I could enable S3TC on r300g without this library (as it could be done
with r300c) to check if the textures sent to the card without software recoding
library will have simmilar effect.

Have you tested whether the corruption happens with r300c too? It does with WoW
(although r300g has fewer other bugs).

Still, I'm glad you at least have a workaround available.

Interesting theory - should this bug now include a title tag for r100-r500 DRM
kernel modules?

Not necessary, it's just a theory. It would be interesting to rewrite that
function to use the 3D engine on r300 and see if it fixes anything.

I've done some more testing in spectate mode (so I can go closer to walls, even
fly through them) and my theory about 60->30 FPS drop does not work everytime
as there are walls which can look at (very close look) where I have 60 FPS and
the problem is still there but it might be something with lightning with
lightmaps on just s3tc textures. The textures which (always) are not broken
(probably not s3tc) when s3tc+lightmaps are enabled on the same map have
working lightmaps effect.

A simpler test could be to use r200_copy_dma instead of r100_copy_blit for the
.copy hook in radeon_asic.c. (On my mobile RV350 that seems to perform better
anyway...)

I replaced r100_copy_blit with r200_copy_dma in both radeon_asic.copy and
r300_asic_pcie.copy, but didn't notice any significant difference in the
texture corruption. (This was with kernel 2.6.35.6.)

On r300c enabling (in menu) lightmaps effect does not change anything as it
could be enabled when GLSL is enabled but on r300c glxinfo reports only:
OpenGL vendor string: DRI R300 Project
OpenGL renderer string: Mesa DRI R300 (RV350 4150) 20090101 x86/MMX/SSE2 TCL

Assuming that's with your AGP RV350, r300_asic.copy is used. Did you mean that
instead of radeon_asic.copy?
