Abstract

Embodiments of the present disclosure implement hardware-based snoop logic streaming timers for input/output (I/O) communications between a host and a shared network adapter in a computing system. The disclosed embodiments describe a hardware-based snoop logic and snoop logic timer function control of input/output (I/O) processor monitoring a defined memory area to detect a completion queue entry being written to a completion queue, and implementing streaming timers and interpacket timers, based on the completion queue entry and predefined configuration information for an associated host interface connection, to provide streaming data status, interpacket arrival times, and streaming timer expiration for the associated host interface connection.
