No, that's not the point of OFFSCHED. It's about offloading kernel functionality to a peer, and as it currently exists after some years of development. kernel functionality only. Raz has already stated that hard RT is not the point. <quote> (for full context, jump back a bit in this thread) > On the other hand, I could see this as a jump platform for more > proprietary code, something like that: we use linux in out server > platform, but out "insert buzzword here" network stack pro+ can handle > 100% more load that linux does, and it runs on a dedicated core.... > > In the other words, we might see 'firmwares' that take an entire cpu for > their usage. This is exactly what offsched (sos) is. you got it. SOS was partly inspired by the notion of a GPU. Processors are to become more and more redundant and Linux as an evolutionary system must use it. why not offload raid5 write engine ? why not encrypt in a different processor ? Also , having so many processors in a single OS means a bug prone system , with endless contention points when two or more OS processors interacts. let's make things simpler. </quote> -Mike -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
