Re: Why is Linux not RTOS?

Ok, let's clarify somethings ;) First of all I really recommend this links: http://www.linuxjournal.com/article/9361 http://rt.wiki.kernel.org/ The real-time implementations previously commented in the list relies on "interrupt shielding" (forcing interrupts to run on a reserved CPU) and "CPU pinning" (forcing real-time tasks to only run on a CPU which doesn't run any other tasks), so we can't say it's a 'real' real-time ;) (it does not take the best advantage of multiple cpu's for example and needs more than just one in anyway). Legal notice: It's just my personal contribution. P.S.: Sorry my delay to answer that ;) On Thu, 2007-04-05 at 15:37 +0530, Raseel Bhagat wrote: > Hi Tzahi, > > On 4/5/07, Tzahi Fadida <Tzahi.ML2@xxxxxxxxx> wrote: > > What is this i hear about PREEMT_RT from VirtualLogix: > > http://www.wirelessiq.com/content/newsfeed/9867.html > > I think the author is trying to mention the different innovative > solutions to the latency issue in the GPOS Linux Kernel.
