This works provided we tell the pipeline to enter printk-sync mode when the watchdog kicks. So I'd say that we could probably do a better job in making the pipeline core smarter wrt NMI watchdog context handling than asking Xenomai to dup the mainline code for having its own NMI handling. > > Jan > -- Philippe. _______________________________________________ Xenomai-core mailing list Xenomaifirstname.lastname@example.org https://mail.gna.org/listinfo/xenomai-core
