NAME

6       rt-migrate-test - real-time task migration program
7

SYNOPSIS

9       rt-migrate-test  [-ceh]  [-p  prio]  [-r  time] [-s time] [-m time] [-l
10       loops] [nr_tasks]
11

DESCRIPTION

13       Test real-time multiprocessor scheduling of tasks to ensure the highest
14       priority tasks are running on all available CPUs
15

OPTIONS

17       This  program  follows  the  usual  GNU  command line syntax, with long
18       options starting with two dashes ('--').
19
20       In the summary of options, a value in brackets (), indicates a  default
21       value
22
23       -D, --duration=TIME
24              Specify a length for the test run.
25              Append 'm', 'h', or 'd' to specify minutes, hours or days.
26
27       -p, --prio=prio
28              base priority to start RT tasks with (2)
29
30       -r, --run-time=time
31              Run time (ms) to busy loop the threads (20)
32
33       -s, --sleep-time=time
34              Sleep time (ms) between intervals (100)
35
36       -m, --maxerr=time
37              Max allowed error (microsecs)
38
39       -l --loops=loops
40              Number of iterations to run (50)
41
42       -e     Use equal prio for #CPU-1 tasks (requires > 2 CPUS)
43
44       -c, --check
45              Stop if lower prio task is quicker than higher (off)
46
47       -h, --help
48              Display usage
49
50       [nr-tasks]
51              number of tasks to run (number of cpus + 1)
