The special kernel modules should not be needed as uio-pci-generic and vfio-pci
that are already in the kernel are working. So no DKMS planned.

I did not yet enable Xen/dom0, yet. Maybe as a next step.

It was said that the library did some runtime detection and the only parts still
pulling in built-time optimizations would be include file macros which then
could be activated when building against it. But I am not sure about it, so I
would currently not want to claim any support in the readme. Might be something
else to add later.
