            Bug ID: 91632
           Summary: Crash in nouveau
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

I have been looking into why QtWebEngine crashes with the nouveau driver, but
the crashes appears asserts in the driver and not our code.

Any idea about what could trigger it:

I've seen that a few times... My analysis was that there's a fixed number of
GEM objects and we're running out of them. Which means that the GPU is either
locked up or way way WAY behind. However I haven't confirmed any part of
this... just based on reading the code. In my case, the GPU was, in fact,
locking up.

The original qtwebengine bug is at https://bugreports.qt.io/browse/QTBUG-41242

One interesting thing I discovered was that using the EGL/GLES mode instead of
GLX/GL solved the issue. I assume at your level it shouldn't be that different.
So it could be a difference in how EGL vs GLX acts.

The issue was happening for me with Unigine Heaven run with DRI3 + DRI_PRIME=1.
Then I started running it with vblank_mode=0 and all my problems disappeared. I
haven't checked whether removing vblank_mode=0 would cause the issues to
reappear. I was happy to blame it on the DRI3 boogeyman and moved on (I tend
not to have a good grasp on these types of issues in the first place...
normally I wouldn't touch DRI3 but it really makes nouveau dev quite a bit
easier with a primary non-nvidia adapter since I can load/unload nouveau/nvidia
at will and still have things display on my regular screen).

Not sure how vsync would cause the problems, but I was getting actual shader
traps reported in dmesg. Do you (or whoever is having the issue) have that as
well?

Hi,

any news on this issue ?

I'm running quite fresh system (OpenMandriva Lx 3.0) with:
Qt 5.6.1
Mesa 12.0-rc4
libdrm 2.4.68
kernel 4.62

gfx card nv92

and Qupzilla 2.01 crashes for me with this error

I can't start the Qupzilla web browser because of a crash, and the problem
seems to be related to nouveau. I can run qupzilla just file if I use the
--disable-gpu commandline option. Please see
https://github.com/QupZilla/qupzilla/issues/2046 for the original bug I
submitted. I'm going to attach the qupzilla gdb backtrace. I'm using
mesa-12.0.1-5 on a Parabola GNU/Linux-libre system.

Unfortunately "this" issue is a lot of potential issues. The current leading
cause of such errors, assuming an up-to-date libdrm/etc, is multithreading in
the application. Nouveau does not handle this well.

I have a branch which tries to address this:

https://github.com/imirkin/mesa/commits/locking

However it's not quite there yet (although it's a good part of the way there),
and needs a rethink on some of the core mechanisms used. Unfortunately the
libdrm_nouveau api is really not well-suited to multithreading, kicks can end
up resulting implicitly from all kinds of seemingly innocuous actions.

This may not be "all the way there", but I can confirm a significantly more
stable experience with qtwebengine.

As a matter of fact QtWebEngine does use multithreading. Chromium renders in
one thread, and Qt composites in another.
