By default, the priority of a thread is 10. I need some of my threads to run at high priority. So i set their priorities at 20. But it caused some issues like the system time not getting updated etc.
From my understanding OS related threads are running at priorities 10 , 11 and 12 and driver threads at 21, 22 etc.
Could anyone please tell which priority range i should give for my application threads. Scheduling used in round robin.
