Darktable segfault with OpenCL support enabled
After some months I performed a full system update today, and Darktable doesn't start anymore. I don't know how to fix it, and neither how to debug it, whether this should be reported to the Darktable maintainers, or whether it's OpenCL fault, or whether I am missing something (most probably). Before upgrading Darktable was running fine with OpenCL support. Now I get the following output:
$ darktable -d opencl

I tried installing darktable-git but I run into the same problem.
What should I do? Report to the Darktable folks? Use the workaround waiting for an update of Darktable or OpenCL?
Thanks in advance

Re: Darktable segfault with OpenCL support enabled
pacman -Qs opencl would have saved you a pipe / grep construction .
Please post the full output of clinfo (install clinfo if it's not present yet)

Re: Darktable segfault with OpenCL support enabled
clinfo output looks fine and does indicate there's "image support" .
leonixyz, run and post output of
$ darktable-cltest@etrigan63 : to verify you do have the same issue, please post the above and clinfo output from your system.

Re: Darktable segfault with OpenCL support enabled
Same issue here, it's a few weeks now. I have an Optimus setup, working with optimus-manager.
I have tested both the default and the -lts kernel, and tried rebuilding darktable manually to no avail. Running without OpenCL support works around the issue, but it makes the program so slow it's really hard to be productive.

Re: Darktable segfault with OpenCL support enabled
Attaching output for darktable-cltest from an unstripped build. The issue seems to be with the Intel card only. I will try to set up my darktablerc to use only the nVidia and see what happens.
this is darktable 3.2.1 reporting a segfault:
warning: Currently logging to /tmp/darktable_bt_1RRZR0.txt. Turn the logging off and on to make the new setting effective.

Re: Darktable segfault with OpenCL support enabled
Tried to force various opencl_device_priority settings in darktablerc, to no avail. It looks like first OpenCL has to be correctly initialized for all devices, and then Darktable applies the device filter.

Re: Darktable segfault with OpenCL support enabled
leonixyz, I think we are seeing the same error, however your output does not contain the debug data. Can you install the gdb package and run the command again?

Re: Darktable segfault with OpenCL support enabled
The issue has been reported at https://github.com/darktable-org/darktable/issues/5842 and it has been root-caused to a bug in the Intel OpenCL stack, which can be worked around by downgrading the intel-graphics-compiler package:
pacman -U https://archive.archlinux.org/packages/i/intel-graphics-compiler/intel-graphics-compiler-1%3A1.0.4361-2-x86_64.pkg.tar.zstdreaming in digital / living in realtime / thinking in binary / talking in ip / welcome to our world

Re: Darktable segfault with OpenCL support enabled
The new release of
intel-graphics-compilersolves the issue. Please mark as resolved if you don't see the issue anymore.
