Fixed-Priority Scheduling Policy vs Round-Robin Scheduling

[Kishore Kumar Pusukuri]

Does Fixed-Priority Scheduling Policy function similar to Round-Robin scheduling with fixed time-quantum (somewhat like SCHED_RR in Linux) ?

Please let me know.

Thank you.

I am not familiar with SCHED_RR, but with FX priority scheduling
your priority does not change. If you do an IO you return at the
same priority, if you exhaust your time quanta, you return at the
same priority. With TS your priority changes depending whether you
give up the CPU voluntarily (IO for example) or exhaust your timeslice.
With FSS your priority is adjusted so that you will get your fair
share of resource.
