Trying to understand the nvidia-drm ports

Hi,

Forgive my multiple questions on trying to understand all this;  I had
some of these questions a few months ago already but punted on them...


I am looking into some mandatory LinuxKPI changes and I found that some
of the functions I am looking at are in [patch] files for (some) of these
ports.  That said, it also seems some changes are expired as they are
supporting non-supported FreeBSD versions.


What I am trying to understand is what each of the three versions are
for and how much overlap/duplication is there between these ports.
Fells like it's really one per drm version with three falvors and the
flavor being the nvidia-driver version?

From what I see the *-kmod port is the main one including the patches
and the other two are child ports for different NVIDIA-driver versions
under the same drm-kmod version?

Further nvidia-drm-kmod only lists two versions: 66 for ~15 and newer, 61 for
the others.  What are all the other versions for then?

And lastly, why does nvidia need its own copy of [nividia-]drm.ko, which
is, as far as I can see, based on the drm-kmod versions from github (hence
also the same 5.15/6.1/6.6/...)?

Any explanations would be greatlt appreciated.
