Hello Yogi, Looks to me like the test task is set up as periodic, and after doing a little bit of number processing each time around, it yields the CPU for other things to execute (i.e. other Xenomai tasks or the OS), and expects to wake up again at the next delta T. The latency is then how much time passed between the mark where the thread was targeted to start up again and when it actually did start again. The source is in src/testsuite/latency in the xenomai-2.6.3 tree, so you can open that up and see for yourself as well! It looks fairly simple so I think you can verify.
