Processor affinity for processes.
- Split up run queues so that every cpu has one.
- Make setrunqueue choose the cpu where we want to make this process
runnable (this should be refined and less brutal in the future).
- When choosing the cpu where we want to run, make some kind of educated
guess where it will be best to run (very naive right now).
Other:
- Set operations for sets of cpus.
- load average calculations per cpu.
- sched_is_idle() -> curcpu_is_idle()
tested, debugged and prodded by many@
