OpenCL problems with new long lived drivers - Error 221 in clCreateContext call

jcmarginal · July 31, 2017, 9:14pm

Hello friends, I was running last long lived drivers (375.66) and everything was working fine. Few days ago I made an update to new long lived drivers branch (384.59) and started to encounter issues with OpenCL acceleration. For example when using Daktable “Use OpenCL flag” in settings is greyed out. This setting was working with previous drivers. So I tried running darktable with debug opencl command (darktable -d opencl) and it showed this error:

Then I tried running oclDeviceQuery and it shows this error:

I tried to downgrade kmod-nvidia (to previous one - 375.66) and got these results:

Also oclDeviceQuery runs fine with older drivers:

I am running Enterprise Linux 7.3 with nvidia drivers packed from elrepo (I am 99% positive elrepo isnt source of this issue since all the drivers before were running perfectly fine and they did not change anything in last package). I just want to ask if anybody else encountered this behaviour with new drivers and if yes how can we solve it. I cant find anything related to this issue on the internet. I also tried running the softwares with sudo and got the same error. If you need any more information or testing please let me know and I will be happy to provide it.

P.S.: in both cases I had opencl-filesystem opencl-headers and ocl-icd installed

Have a nice day :)
