           Summary: texture corruption in r600/r600g when using DRI2, no
                    texture corruption in r600 with dri1
           Product: Mesa
           Version: 7.10
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: nenolod@systeminplace.net


hi,

i get texture corruption as seen in the attached screenshot when using dri2. 
when running more 3D intensive applications (like say, etracer), the texture
corruption increases resulting in some graphics primitives not being rendered.

this does not happen with DRI1, with DRI1, there is no corruption and all
primitives are rendered as expected.

this is on linux 2.6.38.6 with alpine patches, mesa 7.10.2 and xorg 1.10 with
xf86-video-ati 6.14.1, libdrm 2.4.25 and uclibc 0.9.32-rc3 (also with alpine
patches).

there are some bugs that look similar to what i am seeing, but they are all
marked RESOLVED, and none of them mention DRI2.

it seems that attachment sizes are limited.

see http://nenolod.net/~nenolod/radeon-dri2-gltexture-corruption.png for an
example of what i am seeing.

i think this is due to incomplete writes to the card or perhaps an off-by-one
of some kind.

Judging by the screenshot this may be a duplicate of bug 33824.

The logout effect in KWin uses automatically generated mipmaps + LOD bias to
blur all windows except the dialog in the center of the screenshot.

Does the problem go away if you set ColorTiling to False in your xorg.conf
file?

This is most likely _no_ duplicate, since tiling still has to be force on with
an envvar. And I don't see this happening from the explanations in the initial
post.

re: color tiling, i believe it is disabled by default, but i will try and see
if that is the problem.

i will also get dmesg / Xorg logs when i switch back over to DRI2.

glxinfo, dmesg and xorg log have been attached.

KMS color tiling is disabled.  color tiling is also disabled without KMS.
enabling color tiling on DRI1 does not trigger the bug.

Could be a mipmap generation issue then. Is it still broken with r600g from
upstream Git master?

i don't know, and my concern is mostly with the non-gallium driver right now.

i can test the gallium driver, but i need the normal driver to work as i have
32-bit applications i am running in a debian chroot.  thusly, i do not really
use the gallium driver yet... i only tested it to see if it did the same thing,
which it does.

the result is not the same everytime you trigger that kwin effect though;
sometimes i get part of a console framebuffer (e.g. radeondrmfb).

so would it make more sense for me to test non-gallium driver first?

No one is really working on the non gallium driver any more, so it's not likely
to get much more attention.

well, i will try and see if r600g git master solves the problem. 
unfortunately, i think this means i'm screwed when it comes to running
proprietary apps in chroots.

hi William,

did you have any chance to test r600g git master in the mean time?

The classic r600 driver has been abandoned long ago.
It was replaced by the Gallium driver r600g.

If you have issues with r600g please file a new bug report with component
Drivers/Gallium/r600

Thanks.
