Is there any problem with the above approach? Is there any restriction
such that a cpu which acknowledged the interrupt only should send the eoi
signal?

While I don't think there -should- be any restriction, I also seem to
remember that the xics "emulation" done by the firmware on things like
JS20 requires the eoi to be done from the CPU where the interrupt
originated.

Thanks Ben.

If thats the case, is it okay to call eoi handler from all cpus so that
above case will be satisfied?
