NAME

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

SYNOPSIS

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
-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)
-e: Use equal prio for #CPU-1 tasks (requires > 2 CPUS)
-c, --check: Stop if lower prio task is quicker than higher (off)
-h, --help: Display usage
[nr-tasks]: number of tasks to run (number of cpus + 1)
