If an SMP powermac requires a specific destination setting in the secondary MPIC, either the current mpic_init code is broken there in the same way as on cell, or more broken if it requires something other than destination 0. > But if you think on Cell we can just hard wire in the platform code, > then I'm ok. On cell, I know that destination 0 is always correct because of the wiring inside of Axon. Arnd <><
