[ 13.973636] nvidia: module license 'NVIDIA' taints kernel.
It’s this line where the kernel notes why it is tainted. Somewhere in the nvidia kmod C code, there is a line that looks like this:
MODULE_LICENSE("NVIDIA");
The kernel will print out the aforementioned kernel message if it isn’t one of the open licenses defined in the kernel. There’s more about tainted kernels here:
https://www.kernel.org/doc/html/latest/admin-guide/tainted-kernels.html
There are a variety of reasons why the kernel would be tainted, but in this case it is because a proprietary kernel module was loaded. It doesn’t have anything to do with signed kernel modules or secure boot.
I thought the akmod version of the nvidia driver was the version that was compiled every time the kernel version was changed, is that not the case?
It's compiled as a module, but uses the Nvidia blob. It's not free software.
