Nothing is ever necesary.

My understanding was that xenomai 3.x won't even allow kernel mode realtime anymore, only userspace, so unless you have no intension of ever going to future versions, you probably don't want to design your code that way. I must admit I haven't checked the details of that to see how device drivers for xenomai are supposed to be handled in 3.x. -- Len Sorensen _______________________________________________ Xenomai mailing list Xenomai@xenomai.org http://www.xenomai.org/mailman/listinfo/xenomai
