pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmocom-bb/+/39817?usp=email ) Change subject: Set sched RR Priority on main thread ...................................................................... Set sched RR Priority on main thread Since we are still affected by Python GIL, it makes sense to also set the main thread (which is actually also expected to be real time) to a real time priority. Use a slightly higher rr prio (prio + 1) to the clckgen thread.
