So we are discussing driver development here? That often happens in kernel space even under Xenomai. Already studied RTDM for your purposes? It will even leave the door open to put your applications into the kernel - though we would surely not recommend this as first choice. > > What type of hard real time support ? is it _seriously_ support or > _just_ support ?

It is very serious because most of the user-space services are internally built upon the same functions that are available to kernel space as well. And if you ever happen to hit a corner case that was untested and buggy, we are awaiting your report and will work hard to fix any remaining issue (of course, we will be even more happy when receiving patches ;) ). > > [sorry for my bad english ] No need to excuse, it isn't bad.
