First , not all services are children of init. there are workqueues, kernel daemons, softirqs and so on. offlet provides hard real time,in the sense that one can pre-determine how long an operation cost, it is NMI mode after all. Also, this is why i chose to implement a 1us timer, because i can do it. > >From what I quickly gathered, you are running parts of the kernel > space on the second CPU set, or is that too simple a statement? I am running **no kernel** on the offloaded processors, but offsched code, and the rest of the processors run the "kernel". > > Looks like a very fresh approach, nice project!
