[SCHED] any modern replacement for RT_RUNTIME_GREED in the mainline kernel?

[Chris Friesen]

Hi all,

Some time back 
(https://lore.kernel.org/lkml/fa5b1b55d8934c6a0e02e04a7ad6afdf4012c2e0.1478506194.git.bristot@xxxxxxxxxx/) 
a patch was proposed that would allow high-CPU usage RT tasks to use 
100% of the CPU as long as there were no non-RT tasks that wanted to 
run, but if a non-RT task did want to run the RT-throttling would kick 
in to prevent starvation and deadlocks.

It was rejected for philosophical reasons, with a mention of a 
hypothetical deadline server being the "proper" solution.

Has anything been done in this area in the years since then?

Thanks,
Chris
