That suggests it could be cpu.rt_runtime_us == 0, since all tests are<br>
trying to use realtime scheduler.<br>
<br>

<br>
Above doesn't help much, since you are not tracing child processes.<br>
<br>
1. Can you run this instead:<br>
/opt/ltp# strace ./testcases/bin/sched_setparam02<br>
<br>
2. Can you check what is the cpu.rt_runtime_us for pid that runs the test?<br>
<br>
# cpu_mnt=$(mount | grep "type cgroup (.*cpu[,)]" | awk '{print $3}')<br>
# p=$(cat /proc/self/cgroup | grep ":cpu[:,]" | sed "s/.*://")<br>
# cat $cpu_mnt/$p/cpu.rt_runtime_us<br>
