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

Above doesn't help much, since you are not tracing child processes.

1. Can you run this instead:
 /opt/ltp# strace ./testcases/bin/sched_setparam02

2. Can you check what is the cpu.rt_runtime_us for pid that runs the test?

# cpu_mnt=$(mount | grep "type cgroup (.*cpu[,)]" | awk '{print $3}')
# p=$(cat /proc/self/cgroup | grep ":cpu[:,]" | sed "s/.*://")
# cat $cpu_mnt/$p/cpu.rt_runtime_us
