Soft interrupt in multi-core environment

Hi, everyone

When network card interrupts occur in multi-core system,
what core is used by soft irq for network interrupts?
That is, for example, if the IRQ happens in core 0,
does the soft irq run on the same core ?
Is it possible for soft irq to use other core different from hard IRQ?

Thanks in advance.

Best Regards,
J.Hwan Kim
