HP ZBook 15 G2 - Optimus hardware Using legacy BIOS, option "Hybrid Graphics" set to "Auto". If set to "Enabled" the crash doesn't occur. The NVidia card is a NVIDIA Quadro K610M with 1 GB. I'm suffering the same situation, all worked fine until kmail 5.3.0 came along with qtwebengine. Crashes at random times, from as soon as the application is up, to clicking on a new folder or just when it feels like. I can never get anything from drkonqui as it always crashes when it tries to load after kmail crashing. Here is one of the crashes when i launched kmail from cli kmail Pass a valid window to KWallet::Wallet::openWallet(). void AdblockManager::reloadConfig() false AdBlock::AdblockManager(0xfa2ce0) this

You can try my branch at https://github.com/imirkin/mesa/commits/locking which has helped some people. However it's incomplete and I don't plan on pushing it in its current state. You can remove nouveau_dri.so from your installation, or avoid using applications that use multi-threaded rendering (this is a *very* recent trend, up until recently the only applications that used GL were games/CAD tools, and only very rarely used multi-threaded rendering). For well-supported open-source drivers, consider Intel or AMD for your next purchase. Ilia any chance you can merge these locking patches into main mesa tree ? Things are getting worse... KDE Plasma is using more and more QtWebEngine and this means such crashes with nouveau will occur more frequently. (In reply to Tomasz Paweł Gajc from comment #4) > Ilia any chance you can merge these locking patches into main mesa tree ? > > Things are getting worse... Nope - none. Those patches are broken-by-design for the general case. Either don't use nouveau_dri.so or don't use [recent versions of] KDE. I've heard some rumors that there's some sort of env var that'll disable GL use by KDE. Or maybe tell it not to run when it detects nouveau. I don't know the details. I believe there's an effort underway to address this, but not from me. (In reply to Ilia Mirkin from comment #6) > Nope - none. Those patches are broken-by-design for the general case.

Any hints who may be that special one ? BTW i've applied your patches https://github.com/OpenMandrivaAssociation/mesa/commit/5657638feb4d45e0c6be04a3326ea3a93e403bc7 Currently i'm testing this mesa build, and i must admit that qupzilla, kmail and other applications that use Qt5WebEngine or ny multi-threading OpenGL has stop crashing.

The present situation is that nouveau does not support threads concurrently calling into it. This was never a problem until software that had no business doing anything with GL or nouveau started depending on it without any kind of analysis of end-user impact (or perhaps they did analyze it and didn't care since they felt that no one uses nouveau). Somehow the nouveau developers are stuck with the fallout.

I'll be sure to tell people to try an upstream version of mesa should they mention that they're using OpenMandriva. (Note that OpenSuSE attempted something along those lines too, but ended up just not shipping nouveau_dri.so, I believe.) I'm going to go ahead and remove that branch to avoid any further confusion about its suitability. I figured it might let a handful of advanced users make use of their applications, but it's turning out to cause more harm than good.

I've checked SuSE, Fedora and Arch sources for Mesa, and these distros DOES ship nouveau_dri.so Tomasz - please don't go around messing about with the bugtracker. I know this stuff isn't locked down, but all the blocks/etc stuff is meant for active project contributors (as well all the importance bits). You're just conflating lots of potentially unrelated issues into one, and generating lots of unnecessary notifications. If you're interested in getting more involved in nouveau, feel free to join on irc, #nouveau on freenode.

Thanks Ilia, for cleaning all the related bugs (yes i did my job carefully, and read all the attached logs etc), so next reporters will create new bugs, instead of get clear information like, Mulit-Threading OpenGL is broken in nouveau DRI drivers, Propsed solutions are: * use LLVMpipe DRI driver * buy AMD/intel gfx card * uninstall Plasma and live in TTY cave (In reply to Tomasz Paweł Gajc from comment #12) > (In reply to Ilia Mirkin from comment #11) > > Tomasz - please don't go around messing about with the bugtracker. > > Thanks Ilia, for cleaning all the related bugs (yes i did my job carefully, > and read all the attached logs etc), At least a bunch were unrelated. It may be hard to tell because you're not intimately familiar with how nouveau works, as well as the various differences across generations. > so next reporters will create new bugs, > instead of get clear information like, Oftentimes bugs look identical, but they turn out to be quite different. I want every bug reporter to open a fresh bug. If it's identical, I'll mark it as a dup. Integers are cheap, I don't think the fd.o bugtracker is going to run out of id's too soon. (Sorry, René, for all this spam that has been thrust upon you.) > Mulit-Threading OpenGL is broken in nouveau DRI drivers, > Propsed solutions are: > * use LLVMpipe DRI driver > * buy AMD/intel gfx card > * uninstall Plasma and live in TTY cave To be clear - access from multiple threads (or multiple GL contexts) isn't the issue - it's simultaneously calling into the driver from multiple threads which doesn't work. (The distinction may be subtle, esp to the layman, I'm just being pedantic because GL is complicated and has lots of different usage models.) I'd be happy to put up a statement on nouveau.freedesktop.org about the situation if you can send me a private email (or one to the ML if you prefer) with some specifics about what is problematic. Being unfamiliar with the Qt/KDE world, it's not immediately apparent to me. > Sorry, René, for all this spam that has been thrust upon you.
This doesn't matter at all, I'm glad when things are moving on and if there is new information appearing from discussions.
I'm still open to help here, making valgrind reports of components, whatever help I can provide. Unfortunately, I don't know internals neither of nouveau nor of QtWebEngine and plasmashell, I'm just using (and testing) them. So I need a clear announcement what to do.
I'm using OpenSUSE Tumbleweed and I have currently uninstalled the package Mesa-dri-nouveau you already mentioned to be split off by the OpenSUSE maintainers. But at the end their patches seemed already no longer to hang up my "cutting edge" plasmashell with KMail system. I have still problems with plasmashell running into a loop eating the full CPU power unless killed and restarted. And the (QtWebEngine-based) KMail getting very slow from time to time when navigating through messages, but both issues happen already with uninstalled Mesa-dri-nouveau, so this might be a different problem.
Regarding buying a graphics hardware from a different vendor - I just cannot do this, it's built-in to my work notebook I received from my employer :-)

may be I should link those here (Ilia, please don't be mad at me): https://github.com/karolherbst/mesa/tree/mt_fixes_take2 (last update from 13 april 2019) https://lists.freedesktop.org/archives/nouveau/2019-January/031968.html ([Nouveau] Nouveau channel resets userspace handling) with links to Karol's github. Also, not sure if it helped or I was just lucky, but running kernel 5.1.6 with CONFIG_IOMMU_DEFAULT_PASSTHROUGH=y and CONFIG_PREEMPT=y CONFIG_PREEMPT_COUNT=y CONFIG_PREEMPT_RCU=y CONFIG_PREEMPT_NOTIFIERS=y CONFIG_DEBUG_PREEMPT=y [low-latency desktop in kconfig] apparently helped my stability with nouveau and 01:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 8800 GS] (rev a2) but I can't be ubersure, may be this is weather, or power (un)stability ..currently uptime is '05:18:58 up 6 days, 1:10, 2 users, load average: 0.85, 1.04, 1.05' and before this same machine was staying on and s2ram for two weeks. So, may be preemtion level actually can play some role? (I once run into bug where nouveau stopped working for older machine if I build my kernel without any preemtion - https://bugs.freedesktop.org/show_bug.cgi?id=58615 comment #13) -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
