1. Test while in idle status.

Bind “latency” to core 3, use 250us cycle to do stress test for one day.

$ sudo taskset -c 3 /usr/xenomai/bin/latency -c 3 -T 86400 -p 250 -s -g hist.txt

2. Test under extra high CPU/GPU/IO/Disk/Scheduler workload.

$ sudo taskset -c 3 /usr/xenomai/bin/latency -c 3 -T 86400 -p 250 -s -g hist.txt

$ sudo taskset -c 1 glmark2 –-run-forever

$ stress -q -i 4 -q -c 4 -q -d 4 --hdd-bytes 20M -q -m 4 --vm-bytes 10M

$ while true; do sudo taskset -c 1 hackbench -s 512 -l 200 -g 20 -f 50 -P; done
