Just to confirm, cpuset.sched_load_balance doesn't work with RT, right? You cannot have tasks for sub-domain 2 to utilize bandwidth of sub-domain 3, right?
__1__ / \ 2 3 (50% rt) (50% rt )
For my application domain it would be interesting to have rt_runtime_ns as a min. of allocated rt and not a max. Ex. If an application of domain 2 needs to go up to 100% and domain 3 is idle, then it would be cool to let it utilize the full bandwidth. (we also could have a hard upper limit in each sub-domain, like hard_up=0.8, i.e. even if we could get 100%, we will only utilize 80%); in other words, rt having the same cpu bandwidth management behavior as the "best-effort" tasks.
Could this be done?
