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

--json=FILENAME

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)

[NR_TASKS]

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