It's possible to use global properties even with cpu_arm_init(), if it's registered for CPU type before cpu_arm_init() is called. Than that property would be applied to every new CPU instance by device_post_init() hook on before object_new() returns. > > Andreas -- did you have any thoughts/plans/code in this area? > Splitting the realize part out of cpu_arm_init(), or > providing a cpu_arm_init_dont_realize() [ugh], would be > easy to code but is it going in the right direction? > > thanks > -- PMM > -- Regards, Igor
