That's it, yes. Basically the support already exist in GNU Mach, it just has never been tested for a long time and bits have probably got broken with other changes. > So, to implement SMP, we have to add IPI support in process scheduler The process scheduler probably already has the support. What is missing is the hardware driver for SMP: enumeration and initialization. Samuel
