When running Davinci Resolve on Manjaro Linux with Kernel 4.9.92-1 on my new Dell XPS 13 9370 with the Intel i7-8550U w/620 graphics, I get the following issue:

Intel i7-8550U
Intel UHD Graphics 620
Dell XPS 13 9370
Linux 4.9.92-1
Beignet 1.3.2-2
Davinci Resolve 14.3-1

A test is clearly failing, which is disabling the openCL device, and causing the application to crash. If I add the self test ignore I get:

export OCL_IGNORE_SELF_TEST=1

Happy to help test any fixes, I believe this is an issue with Beignet, not Resolve, but if you think that isn't the case I can try and log an issue with them too.

Thanks

This issue still persists. :(

[hellozee]

Same here, the issue pops up in the terminal when I start Nuke, so definitely not a resolve specific thing

CPU : i5-7200U 
Kernel : 4.19.6
Beignet : 1.3.2-5
Distro : Fedora 29

@bag-man @hellozee I am sorry I didn't take care of this bug. right now, Beignet is not actively maintained anymore. I don't have any idea what's wrong behind the error message. One thing I can think of is to run the beignet unit tests see if you can get some hint from failure cases . And I strongly suggest you to try intel-compute-runtime at https://github.com/intel/compute-runtime which is used to replace Beignet.

I have a similar issue:
Beignet: self-test failed: (3, 7, 5) + (5, 7, 3) returned (6, 1064921688, 5)

Ran the unit tests:

pass: 1005
fail: 0
pass rate: 1.000000

@ruiling nice, the failed tests message disappear once started using the compute-runtime, I can now use OpenCL in Blender Cycles

Bisecting points to commit f805337, blanking doNegAddOptimization method fixes the problem on my 4250U.

Try it if you're on a pre-Gen8 chip.

[YamashitaRen]

Commit f805337 seems to fix it.
However, I would like to point out that DaVinci Resolve core dumps when using any of Intel's OpenCL drivers. Please notice that incompatible OpenCL drivers should be uninstalled as they may cause Resolve to crash (e.g. uninstall opencl-mesa if you're using a proprietary equivalent).
