That's correct. The more testers we have, the earlier the RT version under development will become stable. However, there is no guarantee, and sometimes - for example now - tip may even contain unreleased material that runs just for a couple of days on a limited number of machines. Alternatively, if you do not have the time to test software under development and you would like to use it for production purposes, you may want to use the "Latest Stable" PREEMPT_RT release. This "Latest Stable" version underwent heavy testing on a number of different machines, and latency plots and long-term latency recording results are available in all cases. The "Latest Stable" version is announced here -> osadl.org/Latest-Stable, the related QA data are available here -> osadl.org/QA. Hope this helps, Carsten.
