Message-ID: <Pine.LNX.4.64.0703171105270.16125@coffee.psychology.mcmaster.ca> Date: Sat, 17 Mar 2007 11:13:26 -0400 (EDT) From: Mark Hahn <hahn@...aster.ca> To: Con Kolivas <kernel@...ivas.org> cc: linux-kernel@...r.kernel.org Subject: Re: RSDL v0.31 > So in an attempt to summarise the situation, what are the advantages of RSDL > over mainline. > > Fairness why do you think fairness is good, especially always good? > Starvation free even starvation is sometimes a good thing - there's a place for processes that only use the CPU if it is otherwise idle. that is, they are deliberately starved all the rest of the time. > Much lower and bound latencies in an average sense? also, under what circumstances does this actually matter? (please don't offer something like RT audio on an overloaded machine- that's operator error, not something to design for.) > Deterministic not a bad thing, but how does this make itself apparent and of value to the user? I think everyone is extremely comfortable with non-determinism (stemming from networks, caches, interleaved workloads, etc) > Better interactivity for the majority of cases. how is this measured? is this statement really just a reiteration of the latency claim? > Now concentrating on the very last aspect since that seems to be the sticking > point. nah, I think the fairness and latency claims are the real issues. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
