Abstract
A controller is provided, for use in a processing system containing a plurality of processors operable to communicate with a plurality of I/O devices, for directing a first I/O request issued by a first selected one of the plurality of processors to a targeted one of the I/O devices. The controller device comprises a counter for counting a number of retries associated with the first I/O request and comparison circuitry for comparing a count value in the counter with a first predetermined limit, wherein the controller, in response to a determination that the count value in the counter exceeds the first predetermined limit, blocks all other I/O requests issued by the plurality of processors from being directed to the targeted I/O device.
