Note that the kernel modules built here must be used with GSP
firmware and user-space NVIDIA GPU driver components from a corresponding

535.104.05 driver release. This can be achieved by installing
the NVIDIA GPU driver from the .run file using the `--no-kernel-modules`

## Compatible GPUs

The open-gpu-kernel-modules can be used on any Turing or later GPU
(see the table below). However, in the 535.98 release,
(see the table below). However, in the 535.104.05 release,
GeForce and Workstation support is still considered alpha-quality.

To enable use of the open kernel modules on GeForce and Workstation GPUs,
set the "NVreg_OpenRmEnableUnsupportedGpus" nvidia.ko kernel module
parameter to 1. For more details, see the NVIDIA GPU driver end user
