confusing cpu scheduling of linux...

[jahdiel]

helooo..im studying the scheduling of linux..and..

from what i've researched, the processes are on priority arrays. and that RR scheduled RT(real time) processes are always preempted by FIFO scheduled RT processes.

but what if a higher priority RR sched RT process than a FIFO sched RT process in the runqueue arrives? is the FIFO sched RT process preempted? which one gets the CPU?

i'm kinda confused which first to consider. the priority or the sched policy of a process?

i'd really appreciate some help on this..waaahhhhh

I'm quite interested how Linux handles the scheduling, would you mind posting your sources?
