I forgot to put this into my write up, but one reason I think gitlab
CI is a notch better than all the others is that it at least tries to
have an answer here:
- each gitlab repo has its own configuration for where to find the CI
files (also out-of-tree if you go really wild for hw testing maybe)
- you can include gitlab CI files

Which together means you can share common stuff like compile testing
or qemu based testing while easily having specific jobs per
driver/subsystem/whatever that do hw testing. So if media also gains
fd.o gitlab support the media stuff could be in drivers/media/ci (and
at that point we probably want scripts/ci for common stuff).

gitlab has a standalone runner, so at least for the sw-only stuff if
you have some other Ci (like distros that want to test everything)
they should be able to reuse the fd.o specific stuff fairly verbatim,
or at least with some minimal adjustements in upstream. So building a
CI-of-CIs should be doable. Worst case one level below reusing the
docker images should be doable in practically anything that can run a
vm.
