Hmm, I would prefer to just use something, especially as my PPC experiences are quite limited :). But I guess here are qualified people listening who can quickly dig out some config. In arch/ppc/configs of the (DENX) 2.4 kernel are plenty of configurations for the PowerPC boards, e.g. TQM8620_defconfig, icecube_5200_defconfig, TQM866M_defconfig, etc. But we need cross compilation for most of the embedded boards. Do you need the configuration with IPIPE and Xenomai options enabled? ..

We simply use remote controllable power switches to switch the boards on and off. Wolfgang. ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core

Niklaus Giger wrote: Hi everybody If you point your browser at http://ngiger.dyndns.org/buildbot/ (with ending slash please), you will find a first prototype of the continuos integration tool buildbot (http://buildbot.sourceforge.net/) It proves that it possible to automatically retrieve each revison of the Xenomai and compile it for (at the moment) two targets, a stock PPC and a custom PPC405 board (cross-compiling). At the moment it already is useful for me, but I would like to ask your opinion about its usefulness. Would this be useful for you too? Do you have a special target to propose (other architectures, other target like skins, all xenomai components as modules/built-ins, mvm simulator)? This is a really great idea! Of course, I already have another test candidate in mind: RTnet 8). Specifically the PPC environment would be interesting, as our buildbot (sorry, Wolfgang G. ;) ) is typically very busy so that build regressions are sometimes only detected with delay on that platform. Is it also possible to explicitly trigger an update and rebuild? But also for Xenomai I would see this as a very useful tool, e.g. for 2.4 build tests (I must confess I only test sporadically against this kernel). Be warned that setting up a buildbot master/slave using known good configuration is easy and can be accomplished in less than half an hour, but tweaking the master.cfg takes time and errors are not always easy to spot. E.g. I spent about 40 hours to until I could present you this email and the attached documents. Corrections/suggestions to all documents included are welcome. In the attached tar file you find a pdf file with detailed instructions on how to setup a build slave/master for xenomai to experiment with. I am willing to work in the next weeks (or months) to improve the buildbot master, integrate more slaves. If the xenomai developers would like to transfer (now or some time later) the master to another machine this would be fine for me too. Anywhy if this buildbot master generates too much traffic I might be forced to remove it, as the machine is my private small server connected via ASDL (1000kb upstream and only about 200kb downstream for you). My plans to improve include: - fix any error reported by the eventual users of the buildbot - fix some buildbot minor annoyance a) may be a prettier stylesheet b) use the names of the buildsteps as in http://ngiger.dyndns.org/buildbot/hcu3/builds/13 also in the main page) - Handle correctly cases like changes in the xenomai repository which require new configs, new kernel or patch-versions - Not only compile xenomai but also actually run some tests to prove the changes valid. Yep, a very good idea as well. Regression tests, also in combination with more complex applications on top of Xenomai (like RTnet ;): a simple loopback ping test e.g.), would improve the code quality even faster during the development cycles. This will either require buildbot changes to add a step where one can reboot a slave and run the next step with the new kernel (How to handle non-boots?) or add a separate target board whose power supply can be switched off/on by an external device. What I found are either I) Ethernet controlled power switch like http://info.infratec-ag.de/catalog/product_info.php?products_id=830language=enosCsid=a3995263b1f1ca75af33fe9d0d5fa384 or IO-devices, like the II) USB LabJack http://www.labjack.com/labjack_u12.html. Suggestions for a cheaper solution would be always welcome. Is there no reset button you could control via a master station, e.g. by attaching some cheap electronic to a parallel or serial port? I just remember that DENX once had or still have a remote PPC test-lab running. I CC'ed Wolfgang, maybe he could comment on this if and how it could be used.
