I was under the impression that that set priority to a "realtime"
priority, although rereading the man page I don't see any specific
correlation listed between -20 and realtime.
I also do: sched_setscheduler(0, SCHED_FIFO, &sp);
When I do the setpriority to -20, basically everything other than the
main application grinds to a halt. If I use -10 instead, other programs
work fine, but networking is then allowed to interfere with the main
program.
Is this specific enough?
I also should probably have mentioned that my application (actually
three programs on one box) is heavily threaded.

I have CONFIG_PREEMPT and CONFIG_PREEMPT_BKL on.
My application runs
with SCHED_FIFO and has an elevated priority, but not realtime
priority. When I tried setting it to realtime priority it grinds the
networking, control panel, and VGA display applications to a halt.
Uhhh, SCHED_FIFO and "realtime priority" are the same thing.
Can you be more specific?
