Abstract:
A method for addressing an input/output (I/O) device, comprising the steps of:querying, with a first processing unit, a second processing unit for information on base and associated alias addresses for at least one I/O device;processing, with the first processing unit, the queried information to generate at least one base control block indicating a base address and a plurality of alias control blocks indicating a plurality of alias addresses, wherein each control block is associated with an address for addressing an I/O device;processing, with the first processing unit, at least one alias control block associated with the I/O device;determining, with the first processing unit, a base control block associated with the I/O device with which the alias control blocks are associated; andbinding, with the first processing unit, at least one alias control block to the determined base control block, wherein bound base and alias control blocks provide different addresses to address the same I/O device.
