Hi all, I am working with a Xilinx Virtex II Pro evaluation board, which has two PowerPC 405 and I have ported linux 2.6.24 onto that board when there is one PPC405 configured. I'd like to use this board as a SMP platform. Is it feasible? If it works, what steps should i follow? Could you give me some recommendations or any literatures I could refer to? Thanks a lot!

No. The 405 cores are not designed with SMP in mind and it will not work. If the board has discrete memory for each CPU, you might be able to run it in an AMP fashion. josh

No, the PowerPC 405s can’t be used as a SMP platform. The 405 caches are not designed with cache coherency for SMP.
