Simultaneous configuration of remote input/output hubs utilizing slave processors in a multi-processor, multi-RIO hub data processing system

摘要

A method, system, and product are described for configuring remote input/output (RIO) hubs within a data processing system. Each one of the RIO hubs is assigned to one of multiple slave processors which are included within the data processing system. Each one of the slave processors which has an assigned RIO hub then configures its assigned RIO hub. Each RIO hub has an associated data structure that is updated with current configuration information by the slave processor assigned to configure that RIO hub. When the slave processor has finished configuring its assigned RIO hub, the slave processor then sets a configuration flag to indicate the completion of the configuration of the RIO hub.
