testsuite: add clock test
PATCH 1/1 testsuite: add clock test
Hi,
here comes a new testsuite tool to add the required [1] clock validation against unsynchronised TSCs on SMP boxes. It can also be used to detect certain classes of broken clocks (TSCs...) on UP and to measure the drift against the Linux clock (gettimeofday). The latter is interesting to check the potential impact of new tsc-to-ns conversion functions and
- once we provide such a feature - the synchronisation of Xenomai's time base with Linux (or other clocks).
Feedback welcome!
Once everyone is fine with it, I would like to apply it to trunk. IMO we should also add this test to the xeno_test script (if someone feels like providing an add-on patch, don't hesitate).
