Coprocessor providing service address space for diagnostics collection

摘要

Method and system are provided for providing on a service coprocessor 120 a service address space 121 for diagnostics collection. The system includes: a service co-processor 120 attached to a main processor 110, wherein the service co-processor 120 maintains an independent copy of the main processor's address space 111 in the form of a service address space 121; and a storage update receiving component 160 for updating the service address space by receiving storage update packets from the main processor and applying these to the service address space. An instruction pipe 130 may be provided between the main processor and the service co-processor. The main processor may include: a service delegation component 170 for delegating collection of diagnostic data to the co-processor by sending a collection command from the main processor to the service co-processor for collection of data from the service address space.
