We use gtk-doc for the i915 testcase and tooling repo in userspace
(intel-gpu-tools). The setup is somewhat arcane (some build-fu that is
fumbly, and xml files to tie everything together). But it looks pretty
and works well otherwise. It should be at
https://01.org/linuxgraphics/gfx-docs/igt/ but our autobuilder seems
to be screwed up right now.

Of course I considered it as an option, but like doxygen it has it's
own strong opinion about how in-code comments should look like, and
those differ from kerneldoc syntax. Beyond that I don't really see
benefits over any of the solutions proposed here already (either
sphinx or rst or horror! even the hackfest I still carry around in
drm-intel.git branches).

Btw for igt we went with gtkdoc over docygen because a few people on
our team had "doxygen only over my corpse" level kind of strong
opinions. Everyone just loves their own color choice for this bikeshed
;-)
