Or do I misunderstand? Embedded applications span a huge range of sizes, from the very small devices to which you refer, to quite complex devices. The cable settop boxes we develop have over a hundred interrupt sources, typically run 250-300 threads, and have 192+ MiB of memory. For all that, we are very cost sensitive and are under constant pressure to come up with reliable ways to save memory. > Parag -- David VomLehn -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
