A method and system for method and system for efficiently directing interrupts is disclosed. In a computer system having multiple processors, a computer implemented method, upon detecting an interrupt directed to one of the processors, determines a policy for efficiently handling the interrupt. Upon invoking the policy, the interrupt is redirected according thereto to a second processor for handling. The policies include an I/O affinity policy, a local memory policy, and a reduced I/O intension policy. In a multiple processor environment, a computer based system efficiently handles an interrupt directed to one of the processors. The system includes an interrupt dispatching module for redirecting the interrupt from that processor to another processor, where the interrupt is handled. The system also includes an interrupt redirection policy module associated with the interrupt dispatching module. The policy module provides a policy for controlling interrupt redirection, which promotes efficient operation.

In a computer system, a method of controlling coalescence of interrupts includes dynamically basing a current level of interrupt coalescing upon a determination of outstanding input/output (I/O) commands for which corresponding I/O completions have not been received. Deliveries of interrupts are executed on the basis of the current level and in an absence of enabling timing-triggered delivery of an interrupt.

A method and system for controlling interrupt frequency by estimating processor load in the peripheral adapter provides adaptive interrupt latency to improve performance in a processing system. A mathematical function of the depth of one or more queues of the adapter is compared to its historical value in order to provide an estimate of processor load. The estimated processor load is then used to set a parameter that controls the frequency of an interrupt generator, which may be controlled by setting an interrupt queue depth threshold, packet frequency threshold or interrupt hold-off time value. The mathematical function may be the ratio of the transmit queue depth to the receive queue depth and the historical value may be predetermined, user-settable, obtained during a calibration interval or obtained by taking a long-term average of the mathematical function of the queue depths.

A method and system for controlling interrupt frequency by transferring processor load information to a peripheral adapter provides adaptive interrupt latency to improve performance in a processing system. A device driver obtains current processor load information from an operating system or directly from processor usage counters. The estimated processor load is then used to set a parameter in the adapter that controls the frequency of an interrupt generator, which may be controlled by setting an interrupt queue depth threshold, packet frequency threshold or interrupt hold-off time value. The result is that the relative frequency of interrupts is managed in conformity with the current processor load, provide reduced processing latency when the system is relatively idle, which avoids loading the processor with additional interrupt processing overhead when the processor is busy.
