Abstract

Distributed event management in an embedded support processor computer system includes an embedded support processor having an event distribution agent used to communicate with local processes internal to the embedded support processor. A process communicates with the event distribution agent of the embedded support processor and registers for one or more events. Another process signals an event to the event distribution agent of the embedded support processor. The event distribution agent of the embedded support processor notifies each registered process of the signaled event. The event distribution agent of the embedded support processor is used to communicate with a peer event distribution agent included in a main processor of the embedded support processor computer system, and to communicate over a network with a peer event distribution agent included in an attached device, such as a personal computer.
