lot of the scheduling logic is
if you look in sys/src/9/port
and grep for functions like
sched()
schedinit()
runproc()
updatecpu()
repriotirize()
you'll get the logic of the scheduling algorithm. It's mostly
priority queue fair robin I think, with a few hooks to prefer reschedule
on the same CPU.
Context switching is done
