in general we are happy to merge patches for support of any OS, as long as there is
somebody willing to create, contribute and maintain them. We used to e.g. have
FreeBSD support, but in absence of anyone interested in it, we removed them, as it
created too much extra work for the developers/maintainers at the time.

I think the best approach would be to simply detect the support for cpuset_t during configure,
and then conditionally compile the entire file only if configure detected support for it.
This way, the related symbols provided by cpu_sched_vty.c are not available on some platforms
like macOS, but as long as the given application doesn't use them, it will work.

that is correct. This feature is only used by the 'large' osmocom
programs like osmo-bts, osmo-trx, ... in order to configure the most
optimal CPU scheduling.

Not today.
If you'd like, go ahead and work on patches to enable/disable cpuset_t
related support at 'configure' time, and submit them via gerrit, see
https://osmocom.org/projects/cellular-infrastructure/wiki/Gerrit
Thanks,
Harald
