I am curious If somebody knows ported benchmarks which can control cpu utilization or measure worst case execution time(WCET) instead of cyclictest for Litmus-Rt??

If you’re looking to put tightly controlled load on the system, you can take a look at liblitmus’s rtspin application.  You can set up a task that releases X milliseconds of work every Y milliseconds.  The task will run as a real-time task though, so it might not be a good way to create background load unless you’re using the fixed-priority scheduler.
