Wouldn't that break for FIFO and RR tasks?
There's a reason all the scheduler folks wanted a
per-class yield_to_task function :)
Where is the yield_to callback in the patch for RT schedule class?
If @p is RT, what could you do?
If the user chooses to overcommit the CPU with realtime
tasks, the user cannot expect realtime response.
For realtime, I have not implemented the yield_to callback
at all because it would probably break realtime semantics
and I assume people will not overcommit the CPU with realtime
tasks anyway.
I could see running a few realtime guests on a system, with
the number of realtime VCPUs not exceeding the number of
physical CPUs.
