Abstract
A technique for handling queued interrupts includes accumulating, by an interrupt routing controller (IRC), respective backlog counts for respective event paths. The backlog counts track a number of events received but not delivered as interrupts to associated virtual processor (VP) threads upon which respective target interrupt handlers execute. An increment backlog (IB) message is received by the IRC. In response to receiving the IB message, the IRC determines an associated saturate value for an event path specified in the IB message. The IRC increments an associated backlog count for the event path specified in the IB message as long as the associated backlog count does not exceed the associated saturate value.
