Abstract: A system and technique are provided for providing a service address space. The system includes a service co-processor provided with a service address space. The service co-processor is attached to a main processor where the main processor is provided with a main address space. The service co-processor creates and maintains an independent copy of the main address space in the form of the service address space. The service co-processor receives from the main processor a command packet, determines a clock value for initiating a service function designated by the command packet, and updates the service address space until reaching the clock value. The service co-processor then performs the service function at the clock value.

Abstract: A method includes providing a service co-processor with a service address space attached to a main processor. The main processor is provided with a main address space. The service co-processor updates the service address space to create and maintain an independent copy of the main address space. The service co-processor receives a system dump request from the main processor, initiates a system dump, and responsive to initiating the system dump, ceases updating the service address space. The service co-processor, upon completion of the system dump, resets the service address space.
