I read on the list that there is a first try by GP Orcullo, so I start from its work. I'm working on a 3.17.8 kernel on which I ported the Ipipe / Xenomai patch. I validated it on two omaps platform where I don't see regression against previous version of the patch, so I'm fairly confident that the core part is correct. In a second time, I ported the previous effort of GP Orcullo. The current state of the effort is available on https://github.com/adegroote/linux/tree/linux-stable-xenomai-odroid-3.17.y I tested without IPIPE, and with IPIPE. Troubles start with the XENOMAI option. Basically, the kernel seems to hangs when I load any "skin" (I compiled them in modules to be sure). For example, modprobe xeno-native prints Xenomai: starting native API services. but I cannot get back the shell prompt. >>From the Troubleshooting part, I suppose something is wrong with the ipipe_timer, but I don't have much idea where to look for. Can someone give me some inputs about how to trace / debug this issue or/and quickly check if I miss something obvious in my patch. https://github.com/adegroote/linux/commit/81c6ebeb3127efdceb3e31f9d3f1f400ecbb579f.patch Thanks in advance.
