htop tools, processes (or/and threads depending on display settings) having the highest realtime priority (99 from the userland API point of view) with either the scheduling policy
SCHED_FIFO the priority is displayed as
For all the other real time processes, the priority is displayed as a number p defined by:
p = -userprio -1
I am wondering why
htop don't display
-100 for higest priority real time processes ?
