Dear Xenomai users/developers,

I want to measure external interrupt latencies. Therefore, I have a
parallel port loopback connector (25 pins). Pin 9 (D7) and Pin 10 (ACK)
are connected. I would like to trigger an interrupt via Pin 9 and
measure the time till the ISR is entered.

Can somebody give me a hint how to start writing such an application. I
read something about RTDM and I also had a look on the IRQ-Loop
testsuite. I am wondering whether I can reuse some of this code which is
written there. Besides, is it really necessary to use the RTDM framework?

Sorry, but I am really new to Xenomai. I just want to have some small
hints how to start developing.


Thanks in advance,

Markus Franke
