The test code is using the posix skin.
I still don't find any explanation for that behaviour, only trivially testing with and without mlockall() in a bare main routine though. In relation to this, I've rolled out 1.7-02/x86, so that we could close the last pending issue(s) holding v2.3.1 wrt the interrupt pipeline support. Specifically, the -nocow related changes have been amended, and we are now back to the implementation that prevailed in the 1.6 series wrt vmalloc and ioremap memory, while still retaining the ability to break COW eagerly for the RT threads. Feedback welcome on this. -- Philippe. _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
