Nouveau - May 2015 - [Bug 90567] New: Display freeze when starting League of Legends (Wine)

https://bugs.freedesktop.org/show_bug.cgi?id=90567

            Bug ID: 90567
           Summary: Display freeze when starting League of Legends (Wine)
           Product: xorg
           Version: 7.6 (2010.12)
          Hardware: Other
                OS: All
            Status: NEW

         Component: Driver/nouveau
          Assignee: nouveau at lists.freedesktop.org

Nouveau error log - 1

Up until recently, I was able to play League of Legends on Linux with Wine,
using the open source driver nouveau. And that was with great performances.

Since an upgrade of the game (I cannot go back to the old version though),
everytime the game starts, The display freezes (sometimes after up to 5 seconds
but it always does).

The cursor is still moving but typing commands blindly doesn't seem to work.

The network and SSH deamon being still running, I was able to collect some
Kernel logs. I attach them.

I also tried to go back to an older version of the Kernel in case the problem
was in there but that did not help (So I can't bissect the kernel to find
the
possible bug)

I am not sure if the game is doing something nasty or if there is a bug in the
opensource driver.

Logs show all kind of error messages I could find.

The first error messages are the most informative. Can you provide a full dmesg
log from boot until some of those errors happen?

Also, what version of mesa are you using? If not the latest, please try with
the latest.

Hello, thanks for your response.

The version of mesa was just updated by my distro (archlinux) to version : 
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.5.6
OpenGL version string: 3.0 Mesa 10.5.6
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 10.5.6

I'll attach a log that shows the journal when the game freezes. I just
realized
that only the game freezes. Once it's been killed by SSH, I get the control
of
the system back.

Hello Detlev,

Did you test with mesa git?
In any cases, could you please try this attached patch ?

I'm absolutely not sure it will fix your issue but let's try. :-)

Unfortunately, the patch did not fix the problem. Though now, I can Alt-Tab to
switch to other windows and even kill the app with Ctrl-Alt-Esc.

I attach the log for the start of the game.

Are you using libdrm 2.4.60? If so, don't. Either use 2.4.59 or 2.4.61.

--- Comment #12 from Ilia Mirkin <imirkin at alum.mit.edu> ---
OK, well this is phenomenally bad then:

nouveau E[League of Legen[1565]] Unknown handle 0x00000017
nouveau E[League of Legen[1565]] validate_init
nouveau E[League of Legen[1565]] validate: -2

And in your earlier logs:

nouveau E[League of Legen[2046]] Unknown handle 0x0000020e
nouveau E[League of Legen[2046]] validate_init
nouveau E[League of Legen[2046]] validate: -2
nouveau E[League of Legen[2046]] multiple instances of buffer 3 on validation
list
nouveau E[League of Legen[2046]] validate_init
nouveau E[League of Legen[2046]] validate: -22

I guess the earlier log may have happened with 2.4.60 -- that one would trigger
the "multiple instances" error. Unknown handle is really really bad
though.

Ben (or anyone)? I don't see how this can happen... Are we not holding on to
some buffer that we should be? Should pushbuf_refn take a ref on the bo?

Detlev, could you create an apitrace that reproduces the issue? I think that
could ease debugging. (https://github.com/apitrace/apitrace)

I'll get that in place tomorrow.

Note that the first bug could have been reported using 2.4.60, I upgrade
packages almost everyday.

For the rest, this is out of my comprehension scope :) I'll do my best to
give
you all you need :)

I am not sure I will be able to get a trace, the game automatically starts
different programs when setting up the game in wine.

The behavior today is quite random:
 * Sometimes the game crashes
 * Sometimes it freezes while loading
 * Sometimes it freeze when the game starts
 * Sometimes I loose control (keyboard and GUI not responding but mouse still
moving)

I haven't been able to reproduce the bug with Wine running through apitrace.
I'll try again.

First of all, that trace program is awesome !
I did some testing and couldn't fine the trace file. I then realized that it
was located in the folder of the executable.

So, I now have a 65MB trace file. I suppose that only the end is interresting
but I'm not even sure that this is true. Is there any official way to give
you
that file ? If not, I will uploaded to my google drive and make it available to
you.

Thanks in advance :)

Does replaying that trace ('glretrace $file') cause the issues to occur?
If so,
xz -9 the trace, and make it available somehow. Google drive is a common such
mechanism. Just make it readable by anyone.

The bug doesn't seem to be logged in the journal and the screen doesnt
freeze
whet replayed.

though some messages like:
91596 @1 glXSwapIntervalMESA(interval = 1) = 0
91596: warning: unsupported glXSwapIntervalMESA call
107191: message: api issue 1: FBO incomplete: driver marked FBO as incomplete
[-1]
[repeated]

are shown.

anyway, if it helps, here is the compressed trace:

Thanks for the trace, but we can't reproduce the issue. That's strange.

Could you try to generate a new trace and make sure the issue occurs when you
replay it, please?

By the way I just noticed that League of Legends is a free game, so I'm
going
to check it out tonight.

Detlev, I've never played this game -- what do I need to do in order to make
the freeze occur?

--- Comment #20 from Detlev Casanova <detlev.casanova at gmail.com> ---
I'm not sure you can do it with a new account, the game is very restrictive.
The bug occurs with every type of game. To avoid being banned for leaving an
actual game (that's not fair because i would leave a team with 4 against 5),
I
create a custom game with bots:

Launch -> login -> play -> select Custom -> Normal -> Create game
-> Team size:
1 -> Create game -> Add Bot in team 2 -> Start game -> click yes
-> select a
champion -> Lock In -> Wait for freeze.

To generate the trace, I ran playonlinux within apitrace32. I recommand
installing league of legends from playonlinux.

I'll try to generate a new trace tonight.

--- Comment #21 from Detlev Casanova <detlev.casanova at gmail.com> ---
I haven't been able to reproduce the issue with a trace, I tried multiple
ones.

I realized that when retracing, with verbose output, I get this in the end:

451252 @0 glEnable(cap = GL_BLEND) // incomplete
453956 @1 glFenceSync(condition = GL_SYNC_GPU_COMMANDS_COMPLETE, flags = 0) //
incomplete
apitrace: warning: caught signal 11
453956: error: caught an unhandled exception
glretrace+0x2a637c
/usr/lib/libpthread.so.0+0x1065f
glretrace+0x217db2
glretrace+0xf363
glretrace+0xb2d5
glretrace+0xb8eb
/usr/lib/libpthread.so.0+0x7353
/usr/lib/libc.so.6: clone+0x6c
?
apitrace: info: taking default action for signal 11
Erreur de segmentation (core dumped)

The last 2 calls seem incomplete (not completely traced by apitrace ?) and
then, glretrace crashes.

Is there a way to end apitrace32 to properly generate the end of the trace ?

What version of apitrace do you use?
If you use the archlinux package, you should perhaps try to build your own
apitrace from the repo.

Archlinux ships apitrace version 6.1.

With the latest git version, it doesn't seem to segfault but the kernel
errors
are not reproducible...

I don't know what else I can do :/

Quick update. I didn't get to this last night, and won't be able to look
at it
until mid to late June. (Doesn't mean someone else can't look at it
though.)

This is the same issue that supertuxkart 0.9 was having, it'd die in a
glFenceSync. I believe I tracked down the underlying issue and sent a patch to
fix it:

http://patchwork.freedesktop.org/patch/52425/

Please try applying that patch to your mesa build and see if it helps.
