About BWI... A student of mine (added in cc) implemented a prototypal
bandwidth inheritance (based on an old version of SCHED_DEADLINE). It is
here:
https://github.com/eus/cbs_inheritance
(Tadeus, please correct me if I pointed to the wrong repository).
It is not for inclusion yet (it is based on an old version, it is UP
only, and it probably needs some cleanups), but it worked fine in our
tests. Note that in this patch the BWI mechanism is not bound to
rtmutexes, but inheritance is controlled through 2 syscalls (because we
used BWI for client/server interactions).
Anyway, I hope that the BWI code developed by Tadeus can be useful (or
can be directly re-used) for implementing BWI in SCHED_DEADLINE.
BTW, happy Easter to everyone!
Luca
