            Bug ID: 88183
           Summary: radeonsi: R9 280X hangs with SuperTuxKart
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: alexandre.f.demers@gmail.com

In SuperTuxKart, upon loading the first track of the story mode, the display
freezes. The GPU resets but when it comes back everything is messed up and it
keeps resetting continuously.

I'm using latest kernel 3.19-rc3 with the "drm/radeon: fix VM flush..." patches
(also tested without it), latest mesa from git, latest drm from git.

I'll see a journald dump outputs something interesting.

I tried, but it was not conclusive. I'll give it another try tomorrow.

I can reproduce the hang with current Mesa Git master, but not with the Debian
10.3.2 packages. Can you confirm that and if so, can you bisect?

Even with 10.3.2 though, there are GPUVM faults, looks like the CB writing past
the end of DXT5 SRGBA textures:

 Game works fine for me if i disable texture compression in options.

 BTW, they have disabled compression for any intel driver, that might mean this
is not only radeonsi driver issue:

 Compiled latest supertuxkart git, nothing good.

 Blah, even tried it on Windows now and there too it lockup driver randomly...
they really needs to fix their new alpha engine.

Which GPU are you using?

Disabling texture compression doesn't solve the bug.

I'll try 10.3.2 and launch a bisection, but I need to downgrade my newly
updated llvm back to 3.5 first.

 Low end Kabini. Yeah texture compression disable, solve it for 0.8.2-beta
release, but not for current game git i tried now, so yeah bug is there.

 Not sure it is driver bug, as game is really full of bugs and lockuped driver
easely even on Windows for me, it lockup there even on very minimum settings...
but somehow randomly, practically on any settings.

 Man to man said, game is now real shit... sorry to say that i don't know
better words to describe this :) I only understend it uses new forked engine
and game developers needs to fix some driver incompatibilities.

 I also read thir forums and issues on github, there are planty of unsolved
isuess.

I'm confirming that 10.3.2 works fine.

 I tried mesa 10.2.9, 10.3.0, 10.3.2, 10.3.7, 10.4.2 and 10.5-devel. with
current game git all lockup GPU.

 Not to mention Windows 7 32bit and 64bit there are also GPU lockups with
0.8.2-beta release.

IMO, an application should never be able to lock a GPU. But things are as they
are.

I haven't updated STK since I did my apitrace. For me, that version is not
crashing with 10.3.2 (and I'm bisecting, we will see where this ends).

I'm also seeing the VM faults in dmesg.

While bisecting, using today's mesa from git, I don't have any crash/hang...
But the VM errors are still there.

If that's still using LLVM 3.5, maybe it's actually an LLVM regression.

I doubt it, since I've been using llvm-git only for the last couple of days.
But I'm actually rebuilding llvm from git, I'll know later today for sure.

Tested with mesa recompiled with llvm 3.5+ (r226248) and it still doesn't
crash.

Should we keep this bug opened and focus on the VM faults?

Yes. VM faults can cause hangs too. Were you able to bisect the problematic
commit?

Are you refering to the VM faults? If so, not yet? I've been busy with other
things lately, but I could give it a go in the next week.

Has anyone found a Mesa commit yet where the VM faults *don't* occur?
Otherwise, there's nothing to bisect for them.

 There is no good bisect, a go down to nesa 10.1 game needs at least that for
gl3 renderer at is still fault.

 Issue is mostly about that texture compression option for me, i tried
0.8.2-beta and 0.8.2-beta2... only you are better to not start a race before it
get disabled, applied and most importantly exit a game after that because it
does not get really applied :D ... blah, just do:

 MESA_EXTENSION_OVERRIDE=-GL_EXT_texture_compression_s3tc ./supertuxkart

 And it is fine.

To my knowledge, since I've had this video card (a few months), I've been
dealing with VM faults. Here they are triggered in SuperTuxKart, but I've also
reportered them in another bug about Serious Sam 3 (which hangs the GPU in a
few seconds). However, are VM faults only related to mesa or can they come from
somewhere else (drm)?

Note that I'm referring specifically to the VM faults triggered by your
apitrace from comment 5. A VM fault by itself is a generic symptom which can be
caused by many different things, it's more or less the equivalent of a CPU
segmentation fault.

The Mesa driver is most likely in general, though in this particular case it
could also be e.g. libdrm_radeon calculating the surface parameters
incorrectly.

 I can't even start that one, it just throw this:

0 6 glXCreateWindow(dpy = 0x1fd84a0, config = 0x2060a80, win = 58720258,
attribList = {}) = 58720259
6: warning: unsupported glXCreateWindow call
X Error of failed request:  GLXBadFBConfig
  Major opcode of failed request:  155 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  22
  Current serial number in output stream:  20

 Probably shipped gcc libs issue.
