I am testing Qemu's SMP support with a very simple program where every cores execute an infinite loop incrementing a register. The goal is to stop qemu and compare the register values on each core to evaluate the simulation of SMP.
> qemu-system-ppc -M mpc8544ds -cpu e500mc -smp 4 -icount 4 -kernel test.elf Here is a (lightened) log result for two cores from the above test : > IN: > 0x2f4: addi r1,r1,1 > 0x2f8: addi r1,r1,1 > 0x2fc: ba 0x2f4 > > TB 236 1014064768345 > GPR01 4d4a5d4 > PIR 1 > NIP 2f4 > > TB 236 1014064768345 > GPR01 26bfd92 > PIR 2 > NIP 2f4 Having the same time base value, I was expecting to obtain the same R1 values. Am I missing some options? I would like to be sure before starting modifying qemu. -- Julio Guerra
