Performance on kernel 5.9?

[mbod]

I did the test again with the kernel patch I posted here:

Nvidia opencl not working with kernel 5.9

I created my own kernel patch to make nvidia drivers work again. The patch reverts the commit which introduced the TAINT stuff: The patch is for kernel/module.c: --- linux-5.9/kernel/module.c.old 2020-10-14 06:51:57.598066293 +0200 +++ linux-5.9/kernel/module.c 2020-10-14 07:58:16.504570606 +0200 @@ -1431,6 +1431,7 @@ return 0; } +#if 0 static bool inherit_taint(struct module *mod, struct module *owner) { if (!owner || !test_bit(TAINT_PROPRIETARY_MODULE, &owner->taints)) @@ -1449,6 …

And even though the darktable benchmark is without opencl I see a performance improvement. kernel 5.9 is now at 9,68 s. This is bascially the same value as with kernel 5.4 and 5.8.

But I would not over interpret these numbers. The values are so close, even the previous values with a 3,5 % difference, that by all practical means this is not significant.
