priority of kernel threads

["Nilanjan Roychowdhury" <Nilanjan.Roychowdhury@xxxxxxxx>]

Hi,

How can I set the priority of a kernel thread ??

As I understand (looking at the sources)

• User space RT tasks  ( tasks having scheduling policy of SCHED_FIFO/SCHED_RR) can have a  priority from 0 to MAX_RT_USER_PRIO -1.

 

• And Kernel threads can have priority between MAX_USER_RT_PRIO to MAX_RT_PRIO.

 

• And threads having scheduling policy SCHED_OTHER can have priorities between MAX_RT_PRIO to MAX_PRIO -1.

 

If all the above 3 statements are correct ( If not correct me first) then how do I set the priority of a kernel thread ??

 

Regards
