Re: Userspace testsuite issues

Try enabling CONFIG_RTAI_SCHED_LATENCY_SELFCALIBRATE , within "Scheduling options"
Paolo.

Subject: [Rtai] Userspace testsuite issues

Hi,

I'm facing some troubles trying to install the latest rtai releases
(4.1 and 5.0-test1). The base OS I'm using is RHEL 6, on which I'm
installing a vanilla kernel patched with the latest patch available in
rtai sources (linux 3.14.33 with rtai 4.1, and 3.18.22 with
rtai-5.0-test1).

Compilation and installation seems to work fine, I'm able to run the
kernel testsuite, but when I try to run the userspace testsuite, it
doesn't work as expected.

For example, I I try to run the latency test, the output is:

./run
*
*
* Type ^C to stop this application.
*
*

## RTAI latency calibration tool ##
# period = 100000 (ns)
# average time = 1 (s)
# use the FPU
# start the timer
# timer_mode is oneshot

RTAI Testsuite - USER latency (all data in nanoseconds)
2015/12/11 15:21:53
RTH|    lat min|    ovl min|    lat avg|    lat max|    ovl max|
overruns

And after that, nothing happens. I can only stop the test by pressing
Ctrl+C twice.

Any idea about what goes wrong, or a suggestion on what I can do in
order to debug this issue ?

I'm attaching rtai and lunx configuration I'm using.

By the way, I'm already successfully running rtai 3.8.1 + linux 2.6.32
on the same machine (I need to upgrade rtai in order to use a recent
linux kernel which will give us a complete support of the machine
devices).

Thanks.

        Cheers,

                Emmanuel.
