Opencl not working with kernel 5.9

Graphics / Linux Linux

Based on what @dinosaur said, I created my own kernel patch to make nvidia drivers work again. The patch reverts the commit which introduced the TAINT stuff:

https://github.com/torvalds/linux/commit/262e6ae7081df304fc625cf368d5c2cbba2bb991

This is my patch:

It works just fine!
