Getting following error on Ubuntu 20.04. Any workaround solutions for this.
Picking NVIDIA driver sources from NVIDIA_SRC_DIR=/usr/src/nvidia-460.80/nvidia. If that does not meet your expectation, you might have a stale driver still around and that might cause problems.
Getting symbol versions from /lib/modules/5.8.0-55-generic/updates/dkms/nvidia.ko ...

The requirements part of the readme says "Linux kernel above 4.15.0.x".
However, this project uses Linux's RQF_COPY_USER which was removed in Linux 5.8.
It also expects
/include/linux/proc_fs.h:proc_dir_entry(... const struct file_operations *proc_fops)which was changed toproc_dir_entry(... const struct proc_ops *proc_ops)in Linux kernel 5.6.What is the newest kernel that has been tested with this over at Nvidia? Are there any Linux 5.x kernels that would be expected to work as of now?
I'll continue testing kernels a few weeks from now if we still don't know and I have the time. Once we know what the kernel version limit is, I would love to add it to the readme.
