Re: kodi segmentation fault [solved]

Yeah, BayTrail HD Graphics (and from the copredump on the crocus driver) => try mesa-amber.

Re: kodi segmentation fault [solved]

for me it was python again. i downgraded and ignore listed python. I'll keep it like that until there is an new update, unfortunately.

Re: kodi segmentation fault [solved]

So before having read your answer, i tried to both
$ export LD_PRELOAD=/usr/lib/dri/crocus_dri.so
and
# export LD_PRELOAD=/usr/lib/dri/crocus_dri.so
with wesa22 without any succes sad
(the /usr/local/lib… path doesnt exist on my machine)

Then i tried mesa-amber, but it still crashes with segfault. With mesa-amber, glxinfo complains :
«Error : couldn't find a RGB GLX visual or fbconfig»
And glxgears does not work anymore.

I tried to launch kodi from a wayland session (sway) instead of X11 (XFCE) and i just have a black screen, with no crash it seems (top shows a kodi.bin process is living and there is no crashlog reported…)

I can perform other tests or provide log file if needed, but i dont know what else could i do…

Thanks,
Alex

1. it's not a "stub"

Well from what I've read about mesa, gallium, crocus, vulcan and all that very confusing stuff you must not expect very much development for this mesa-amber branch in future as it is only a collection of DRI drivers stripped of all vulcan and gallium drivers. If you consinder 'stub' is the wrong word - sorry.

2. there's a guy w/ a gen7 chip right above you …

I'am totally confused about Intels 'gen'-numbering. Seems like CPUs, chipsets and graphic-cards have their own 'gens'.
According to mesa 22 release notes intel graphics since gen. 7 should be supported. Haswell graphics are Gen. 7 according to the wikipedia link you gave.

3. "HD4000" is not an "Iris Graphics" chip, https://en.wikipedia.org/wiki/Intel_Gra … gy#Haswell

Totally right. It is an Intel HD-Card. Not UHD, not IRIS.
Nevertheless it should be supported by mesa 22 through crocus

No, you dont need mesa-amber. With your given

everything works fine with Intel Gen.7 (Haswell) graphics cards : glxgears, glxinfo, vainfo and kodi!


There was a workaround for Intel graphics given in the wiki to set

MESA_LOADER_DRIVER_OVERRIDE=i965 

environment variable in order to prevent weird display errors with Gen. 9 (KabyLake) graphics in qt-applications and esp. when using LXQt.
This is not needed anymore, the display-errors do not appear even without this setting.
You'll have to remove it to make Kodi work again.

Re: kodi segmentation fault [solved]

So i rebooted with mesa-amber and
MESA_LOADER_DRIVER_OVERRIDE=i965
line in my /etc/environment.

Still those segfault errors (and no more glxgears…)

I found that workround later and previously just rolled w/ "crocus isn't reliable enough" - what still might be the case.

Not sure about the principle, esp. here, but have you tried opening a thread in the discussion of the page?

Here is the return of cat /var/log/Xorg.0.log : https://pastebin.com/6v66B20d

There is

that would say it uses this old driver that used to work…

Let's see what libraries/objects are actually loaded.

strace -f -o /tmp/glxinfo.strace glxinfo

and post that file.

Re: kodi segmentation fault [solved]

And is it expected or mesa-amber should provide it ? if so, should i report this bug to the package maintainer of mesa-amber ? or to mesa-amber «main stream» (dont even know who is it) ?

If this is the default behavior of mesa-amber, cant i go back to some old mesa version maybe setting an environment variable to specify to use an old driver ?

Re: kodi segmentation fault [solved]

libglvnd should™ not try to load libGLX_mesa or in very doubt resort to libGLX_amber - that's why I asked for the environment and whether you can control it to use the proper plugin.
But you're not the only one w/ this resolution issue, https://bugs.archlinux.org/task/74364

Re: kodi segmentation fault [solved]

Ok, so it seems you understand the issue. If i do so, i guess i just have to wait for a new mesa-amber package with the good symlink names. Or it there an easy way for me to correct it or is it «hard coded» in the library and only a compilation can solve it ?

Thanks for the time you gave me,
Alex

Re: kodi segmentation fault [solved]

You can either symlink libGLX_mesa.so to resolve libGLX_amber.so but I'd suggest to just try and "export __GLX_VENDOR_LIBRARY_NAME=amber" instead (see #39)

Re: kodi segmentation fault [solved]

So i created the following simlink in /usr/lib/ :
ln -s libGLX_amber.so.0 libGLX_mesa.so.0

and know the error has changed ! (but it still does not work, but at least, it does something)

Here is the new strace for glxinfo : https://pastebin.com/ggxna2jp where we can see the simlink seems to work : «openat(AT_FDCWD, "/usr/lib/libGLX_mesa.so.0", O_RDONLY|O_CLOEXEC) = 4» at line 200.

I now have just read your post about the environment variable __GLX_VENDOR_LIBRARY_NAME, but it does nothing different : glxinfo -B show the same error as with only the simlinks… («X Error or failed request : BadValue (integer parametre out of range…»)

Re: kodi segmentation fault [solved]

You probably didn't restart X11 after the symlinking and you should (if we go w/ the symlink as workaround) symlink all libGLX_amber.so* libraries - not just the .0 version.

Ok, i created the 3 simlinks .so .so.0 and .so.0.0.0 and i restarted lightdm (i guess it restart X.org) and now glxgears works (one thing fixed, thanks) !

But kodi still has seg fault sad

Re: kodi segmentation fault [solved]

Great. So we've completely swapped the GL implementation, but are left w/ the original error…
While this happens when initializing the KODI render system, the consntant trigger seems to be the logging… so https://bbs.archlinux.org/viewtopic.php … 3#p2030663 ?

Re: kodi segmentation fault [solved]

I tried to downgrade both kodi and python-3 but it does not help. In the kodi_crashlog i can read this at the end :

i found a workaround here : https://github.com/xbmc/xbmc/issues/18076

i just mv libvdpau_va_gl.so.1 to libvdpau_va_gl.so.1_backup and kodi is here again !!!

I'm gonna mark this thread as solved.
