xeno-test [ -l "load command" ] [ -k ] [ -r ] [ -- ] [ latency test options ]
|
|
Run a basic test/benchmark of Xenomai on your platform, by first starting a
|
few unit tests, then running the latency test under the load generated by
|
"load-command".
|
|
By default, the load command is "dohell 900", which will generate load during
|
15 minutes. To generate a more realistic load see dohell help.
|
|
This script accepts the -k option to tell the unit test loop to keep
|
going upon a failing test. Otherwise xeno-test stops immediately.
|
|
If the script is passed the -r option, real-time stress is added to the test,
|
with the help of the "switchtest" test. But beware: the latency test figures are
|
then no longer meaningful.
|
|
For running test in a virtual machine use the --vm option. This option relaxes
|
some of the timing thresholds.
|
|
Any other option passed on the command line is passed to the latency test.
|
|
Example:
|
xeno-test -l "dohell -s 192.168.0.5 -m /mnt -l /ltp" -t 2
|
|
Will generate load including network load using the server at IP address
|
192.168.0.5, some I/O under the moint point /mnt, and the LTP testsuite
|
installed under the /ltp directory, and use the latency test by measuring the
|
timer irq latency.
