FWIW, I think this is likely the only viable option.
The i915 driver is a fast moving target, and I have witnessed the
struggles of full time paid developers backporting and forward porting
drm and i915 features from Linux kernel version to another. It is not a
trivial task. Last I checked, the Linux driver backports project has
also given up backporting latest drm drivers to stable kernel versions.
I don't have any FreeBSD experience and I don't know what kind of team
of developers you have, but it is my educated guess that you'll have
plenty of more productive things to do than trying to maintain a
significant amount of delta with upstream while also trying to stay

The focus and priority of the i915 driver is obviously Linux, but I
don't see us rejecting patches that help FreeBSD if the patches
generally make sense and don't interfere with the main priority.
Good luck with your efforts!
