       rt-migrate-test - real-time task migration program


       rt-migrate-test   [-c|--check]   [-D|--duration  TIME]  [-e|--equal]  [-h|--help]  [--json
       FILENAME] [-l|--loops LOOPS] [-m|--maxerr  TIME]  [-p|--prio  PRIO]  [-r|--run-time  TIME]
       [-s|--sleep-time TIME] [NR_TASKS]


       Test real-time multiprocessor scheduling of tasks to ensure the highest priority tasks are
       running on all available CPUs


       This program follows the usual GNU command line syntax, with long  options  starting  with
       two dashes ('--').

       In the summary of options, a value in brackets (), indicates a default value

       -c, --check
              Stop if lower prio task is quicker than higher (off)

       -D, --duration=TIME
              Specify a length for the test run.
              Append 'm', 'h', or 'd' to specify minutes, hours or days.

       -e, --equal
              Use equal prio for #CPU-1 tasks (requires > 2 CPUS)

       -h, --help
              Display usage

              Write final results into FILENAME, JSON formatted.

       -l --loops=LOOPS
              Number of iterations to run (50)

       -m, --maxerr=TIME
              Max allowed error (microsecs)

       -p, --prio=PRIO
              base priority to start RT tasks with (2)

       -r, --run-time=TIME
              Run time (ms) to busy loop the threads (20)

       -s, --sleep-time=TIME
              Sleep time (ms) between intervals (100)

              number of tasks to run (number of cpus + 1)
