How vPars and its Components Work

Transitioning from vPars A.03.xx to vPars A.04.xx/A.05.xx (CPU Syntax and Rules)

Chapter 2

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
