I/O interrupts
• only bound CPUs can handle I/O
interrupts
• intctl (interrupt control) applies to
only the bound CPUs
I/O interrupts
• at boot: all CPUs can handle I/O interrupts
• after boot:
— when CPUs are removed from a virtual
partition, the I/O interrupts are
automatically reassigned to the other active
CPUs
— when CPUs are added to a virtual partition,
the I/O interrupts are not automatically
processed by the added CPUs
— intctl can be applied to all CPUs
