hello!
I have some difficulty during my studying the schedule of linux-smp and
I wonder if you could give me some help?
There is a field of "policy" in the task_struct structure in
'sched.h',and there are three policies all together,SCHED_RR SCHED_FIFO and
SCHED_OTHER.The first two are used in real_time processes.Is it right? I
wonder why we use these policies? What kind of processes will use SCHED_RR
policy and what about SCHED_FIFO? What kind of policy is SCHED_OTHER ,or
what is the schedule rule of SCHED_OTHER?
Expecting for your answer and thank you very much for your kindness and
attention.
yours
chenli
Best Wishes
