Nouveau - Aug 2014 - [Bug 83079] New: Dota 2 under Wine freezes with Nouveau Drivers

https://bugs.freedesktop.org/show_bug.cgi?id=83079

          Priority: medium
            Bug ID: 83079
          Assignee: nouveau at lists.freedesktop.org
           Summary: Dota 2 under Wine freezes with Nouveau Drivers
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: lukebenes at hotmail.com
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/DRI/nouveau
           Product: Mesa

Steps to reproduce:
1. Install Steam under Wine
2. Launch Dota 2
3. Start Bot match. Lock in a hero.
Expected Results:
Game starts

Actual Results:
Dota 2 will freeze with the following error in the Wine terminal:
err:seh:setup_exception_record stack overflow 2160 bytes in thread 008b eip
7bc5e05a esp 47cb0ac0 stack 0x47cb0000-0x47cb1000-0x47db0000

tested with:
wine-1.7.24
OpenGL version string: 3.0 Mesa 10.4.0-devel (git-83503f9 2014-08-25
trusty-oibaf-ppa+gallium-nine)

Note if I reboot with the Nvidia proprietary drivers, Dota 2 runs flawlessly
under Wine. Dota 2 also works under Wine with AMD catalyst drivers.

What hardware do you have? Are you using d3d9 (via gallium-nine) or opengl? If
gallium-nine, try opengl.

Do you get anything interesting in dmesg when this happens? Can you try an
older version of mesa to see if it's a new issue? (Pretty sure DOTA2 *used*
to
work...)

Wine is from ppa:ubuntu-wine/ppa, so I'm not using gallium-nine.

Could you use a build of mesa that doesn't have the gallium-nine patches
applied? And/or see if older versions of mesa work OK?

@Ilia Mirkin
I had a fresh, unused Kubuntu install on another partition, so I installed wine
from ppa:ubuntu-wine/ppa and used the default Mesa version of Mesa 10.1.3. Dota
2 froze at the same point, after I selected a hero. Steam also gives a 
err:seh:setup_exception_record stack overflow 2128 bytes in thread 00ce eip
7bc5e05a esp 46c40ae0 stack 0x46c40000-0x46c41000-0x46d40000 

Another way to trigger this bug is by previewing an item from your armory or
the store. Again this is with vanilla mesa with vanilla wine(no gallium-nine).

Could you try making an apitrace? Perhaps that would be enough to reproduce the
error. Find a guide for how to use apitrace + wine, esp if you're on a
64-bit
userspace.

Once you have the trace, try replaying it (glretrace). If glretrace also dies,
then success. If not... more debugging.

Ilia,
Here is an apitrace:

Is there anything else I can do to help?

Aa a hint: Why dont you use the native Steam client? Dota2 is available there.
If you can reproduce it there, we have at least spared one layer :)

@Tobias Klausmann
Good point! You are correct, it also crashes with the native port.

This all started from a similar stack overflow error when I was trying to play
CS:GO which does not have a Linux port. I chose to report Dota 2, because
it's
free to play, so it would be easier for others to reproduce.

Simpler Steps to reproduce:
1. Install native Steam under Linux
2. Launch Dota 2
3. Start Bot match. Lock in a hero. OR preview an item in the store

Anything else I can do? Would another apitrace or Dota 2 mini dump help?

I tried to reproduce by replaying the trace, and I didn't get any crashes
with
64-bit glretrace. My 32-bit setup is sadly still on mesa 9.2 or 10.0 or
something, and was missing BaseVertex support, so I got a ton of errors.
However also no hang. I'm going to build a fresh 32-bit install to see if I
can
reproduce.

Luke: Please confirm what issue you're seeing when doing a glretrace on the
trace you supplied.

Mh, for me it does not hang, but crashes "back to desktop". (Native
Linux
Client)
Nothing in dmesg, just a Memory Access Violation error.

Intel works fine...so something odd in nouveau/gallium.

Parsing fails in nouveau_compiler... need to increase the size of the tokens
array. However when compiling for NVE4 (and Luke has a Kepler), it goes into an
infinite loop, which is consistent with a hang. Investigating...

--- Comment #14 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Looks like it goes into an infinite recursion in findFirstUses, which is used
for doing the texture barrier thing (which is done for kepler+). Ugh.
Unfortunately I'm not 100% sure what the desired logic of this thing is...
this
might take a little while to untangle.

avoid infinite recursion in findFirstUses

Does the attached patch help? Should apply to approximately any version of
mesa. It looks like it somehow ends up getting into a loop. Probably due to all
the merging that ends up getting done during RA and manually modifying the
->defs (and uses?) lists. Not entirely sure though.

Mesa + avoid infinite recursion when finding first uses of tex patch
successfully compiles now using nouveau_compiler, going to test it tomorrow i
