No opencl with Intel B580 (Asrock Challenger)

The solution is:
darktable resources **large**
and not default.

No tiling anymore. Full log attached

2.5504 [dev_process_export] pixel pipeline processing took 1.415 secs (2.091 CPU)

Now this is comparable with the benchmark of GPU benchmarks in darktable

Still no idea, why I loose opencl settings after a reboot

After a reboot:
0.1556 [opencl_init] FINALLY: opencl PREFERENCE=ON is NOT AVAILABLE and NOT ENABLED.

Can I do anything wrong, when activating opencl using DT 5.2 and the mouse? Do I have to save anything?

But opencl works, after closing DT 5.2, otherwise the attached log would be impossible. I loose opencl after a reboot.
