vGPU_Unlock's Merged driver is an optional package you can include but if you don't want to use it there's no explicit dependance. We actually enable these features using a vendor neutral API called VFIO-Mdev:

https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/drive...

Here's a few examples of YAML for use with different GPU vendors:

Intel: https://github.com/Arc-Compute/libvf.io/blob/master/example/...

Nvidia: https://github.com/Arc-Compute/libvf.io/blob/master/example/...

AMD: https://github.com/Arc-Compute/libvf.io/blob/master/example/...

The odd one out is AMD that uses a different API due to the fact that the vendor has largely ignored standard open source interfaces in the kernel. We're still supporting that API but unfortunately there are very few AMD cards that work due to the fact that they refuse to release open source code to support their newer cards and they have locked out these features at the firmware level on consumer cards. Fortunately Nvidia and Intel GPUs are very well suited to this functionality and we've got support for most recent consumer cards from both!
