Reset OpenCL Nvidia Drivers without reboot

Nvidia drivers for OpenCL become unresponsive after a while (from one day to the next).

When the issue occurs, clinfo produces:

$ clinfo
clinfo: /usr/local/cuda/lib64/libOpenCL.so.1: no version information available (required by clinfo)
Number of platforms  0

nvidia-smi still functions properly as does the cuda device when using cuda drivers. After a reboot, everything functions properly. I'm also using this device for my display.

Potentially this is related to undocking or hibernating the system.

Is there a way to reset the drivers without rebooting? Any way to discover why the driver is unresponsive?

Reloading the drivers seems to resolve the issue. On Fedora, this can be done with

sudo rmmod nvidia_uvm
sudo modprobe nvidia_uvm
