Subject: [Xenomai-help] Strange results with latency test
Date: Thu, 9 Nov 2006 14:36:33 +0100 [thread overview]
Message-ID: <20061109133632.GA4205@domain.hid> (raw)
Hi,
I tested today Xenomai on my AMD64 (32-bit mode) with the latency
program from the testsuite and I got for lat min negative values.
Can my computer predict the future? :)
How can I interpret these values?
100 us
== Test mode: periodic user-mode task
== All results in microseconds
warming up...
RTT| 00:00:01 (periodic user-mode task, 100 us period, priority 99)
RTH|-----lat min|-----lat avg|-----lat max|-overrun|----lat best|---lat worst
RTD| -1.337| -0.958| 0.970| 0| -1.337| 0.970
RTD| -1.290| -0.907| 1.959| 0| -1.337| 1.959
...
RTD| -1.406| -0.923| 1.884| 0| -1.468| 4.358
---|------------|------------|------------|--------|-------------------------
RTS| -1.468| -0.922| 4.358| 0| 00:00:34/00:00:34
Best regards,
Matthias
