Does FreeBSD support interrupt binding in SMP systems?

Could anybody help me out, thanks in advance.

Linux support the interrupt affinity (interrupt binding) in SMP systems. For example, the NIC interrupt can be redirected by tweaking "/proc/irq/nic_irq_xxx/smp_affinity".

Does FreeBSD has similar features?

thanks,

wenji

Really? I thought it was still in the "intended" basket and hadn't yet been realised?

To follow up to an old thread: yes, this is implemented. You can use cpuset(8)'s '-x' to direct low-level interrupts to a specific CPU, if supported by the underlying hardware.
