eCos SMP support is fairly simple, it assumes equal CPUs and uniform memory access. It certainly cannot cope with CPUs of varying performance and capabilities. There is no way it could cope with heterogeneous CPUs. Neither could it cope with NUMA systems. If you want to run a single OS image on a strongly asymmetric system then eCos is probably not the place to start. The additional complexity needed, while acceptable in a large OS like Linux, is excessive for a small OS like eCos. -- Nick Garnett eCos Kernel Architect http://www.ecoscentric.com The eCos and RedBoot experts Besuchen Sie uns vom 13.-15.02.07 auf der Embedded World 2007, Stand 11-336 Visit us at Embedded World 2007, Nürnberg, Germany, 13-15 Feb, Stand 11-336 -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
