I think it's great, definitely worth exploring. Especially in this era when power efficiency is so important. Offload cores can make sense if the workload suits. Measure and try it out. Although... back when I was an OS guy at Moto, performance analysis revealed that the "offload engine" to handle the BSD, no, I think it was SystemV networking stack interrupt processing really needed to be comparable to, if not more powerful than, the engine that was handling the user code - which at that time was vi and emacs, and the beginning of X. (The offload engine that had been built was really just a generation or two older 68000 card, with the main CPU being an 88K. It couldn't keep up - and it was running an always out of date software that did not have the latest performance fixes.) A mainframe architect came in and said "Surely you don't do a lot of processing in the interrupt handler itself?" Umm, sorry, bad assumption... By the way, that sort of thing was "fixed" multiple times. Trouble is, the code never propagated to the master distro, so it kept having to be refixed. Anyway, offload cores can make sense if the workload suits. Measure and try it out. > Speaking of this (how about SSI/HCM as a shorthand, at least for this > post), I don't see a big advantage. Neither do I. Which is what puzzled me about so much of this conversation. Offload engines occasionally make sense. They are an empirical question: measure, estimate, try it out. Semi-synchronous / hardware cooperative multithreading doesn't really make sense to me. Since at the least you need to be able to kill an accidentally not-very-cooperative thread. I can imagine interrupt based preemption for user threads, with SSI/HCM inside the OS. And I think that might be an easier issue, since seldom will a user thread be holding kernel locks while in user code. (Except... callbacks, bloody callbacks. User calls OS, giving the OS a callback. OS gets a lock, and then calls the user. So the user code is now running, and may be preempted while a kernel lock is held. Bad BAD BAD. Stupid. IMHO callbacks like this are as big a source of bugs as anything else.) Yes, you potentially allow more > interrupt coalescing, but if you have a potential interrupt every branch > which is perhaps a dozen instructions, how much are you really saving? I don't think very much. Especially if you consider the old mainframe strategy of interrupt batching: delay interrupt delivery to allow coalescing. If the interrupt load is high, block interrupts globally, opening windows up only periodically. > Is the hardware that much easier if you can take an interrupt at some > arbitrary software specified point rather than after each instruction? Not in my experience. Although lots of hardware people have tried to take shortcuts, and gotten smacked. But I think Nick's point - apart from having encountered problems like this in hardware - is that software might find this easier. Also remember: most systems do not have a good way of blocking interrupts from user code. > It seems you are mearly reversing the sense of a privilidged instruction > to lock out interrupts. That is, they are locked out by default until > you say you allow them rather than they are allowed by default until you > say they are locked out. Is that a big deal? It does reduce the number of places that you have to analyze for being interrupt safe.
