Hi all,
I have a doubt to clarify.
any scheduler class manage the "pick_next_task" internally (e.g.: CFS use a
red-black tree and the "fair" algorithm, etc).
The main scheduler just:
class = sched_class_highest;
for ( ; ; ) {
p = class->pick_next_task(rq);
if (p)
return p;
/// ...
my question is from the "big picture" point of view:
when the scheduler ask for a new task as to the "highest class" first (RR/FIFO
policy) and then stepping to the next one (CFS).
But, doesn't this treat the CFS process at the same level of the real time
process?
I mean the scheduler ask first to the rt_sched_class and then fair_sched_class
... in a for ...
can you clarify, please where the "real time" task are different?
thanks in advance!
I'd like to be in cc'ed on this.
