Abstract

A data processing system is provided which includes a processor nest communicatively coupled to an input/output bus by a bus controller, and a service interface controller communicatively coupled to the processor nest. The system includes storage for storing commands for the bus controller and associated command data and resulting status data, the storage being communicatively coupled to the processor nest and the bus controller. The service interface controller is configured, in response to received service commands, to read and write the storage, to execute the command specified in the storage, to retrieve the result of the command, and to store the result in the storage.
