[EN] [SOLVED] opencl / error loading nvidia_uvm

[Miho]

Hi all,

I'm trying to get opencl running.
AFAIK the nvidia_uvm module ist required which can't be loaded allthough it was build.

Code: [Select]

modprobe: ERROR: could not insert 'nvidia_uvm': Invalid argument

As far as I found, there was a bug, e.g. [1], but should have been resolved since version 331.79-1.
I tested the versions 331.79-1, 337.25-0... and also the driver directly from nvidia.com – all to no avail.

I'm stuck and therefore I would appreciate any suggestions. Please ask if you need any further information.
thanks in advance and best regards

Pleas update your system, i have added the patch from your linked bugreport to the drivers in our fixes-repo.

Thanks a lot towo for the quick fix – appreciate it!

I can load the module by hand now and it seems to work but I still can't get opencl working. I'll have to dig into this for a sulotion to the problem. Until then I consider this topic solved.

best regards
