rt-migrate-test [-ceh] [-p prio] [-r time] [-s time] [-m time] [-l loops] [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
- -D, --duration=TIME
Specify a length for the test run.
Append 'm', 'h', or 'd' to specify minutes, hours or days.
- -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)
- -m, --maxerr=time
Max allowed error (microsecs)
- -l --loops=loops
Number of iterations to run (50)
Use equal prio for #CPU-1 tasks (requires > 2 CPUS)
- -c, --check
Stop if lower prio task is quicker than higher (off)
- -h, --help
number of tasks to run (number of cpus + 1)
