Hello,
I have submitted the pciutils MiniOS port to upstream (which I should
probably have done 18 years ago :)

What about adding a comment to the stubdom Makefile in a separate patch, like:
# pciutils support has been removed with commit <commit-id>, revert that patch
# in case it is needed again.
I think this would be preferable over unused and probably bit-rotten code in
the repository.
We can point people to pciutils through such a comment.

I don't see why it would be bit-rotten, since the pciutils version in
used is fixed, it's a library that has a quite stable API, and the pci
xen interface is supposed to keep backward compatibility.
Then I'd rather add it to Mini-OS (probably behind another CONFIG option) than
having it in the Xen tree.
Mmm, but how? We don't really want to pull the whole pciutils build into
mini-os :)
TBH, I don't see why the whole Mini-OS specific stubdom maze should be in the
Xen repository. Thinking about the hoops I had to jump through for doing some
of the Mini-OS cleanups (especially regarding config options), having all of
the stubdom stuff in Mini-OS or an extra repository would probably be cleaner.
This is true especially now, as none of the stubdom remains really depend on
the Xen version any longer (apart from the requirement to use a fairly new
Xen).
OTOH before moving stubdom to Mini-OS, UNIKRAFT seems to be a valid alternative.
