Abstract
A method and technique are provided for providing a service address space. The 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. Instructions that modify the main address space are intercepted, storage delta packets are generated based on intercepted instructions, and the storage delta packets are sent to a service co-processor maintaining a service address space.
Claims20
A method for providing service address space, comprising:
- providing a main processor having a main address space;
- intercepting instructions that modify the main address space;
- generating storage delta packets based on intercepted instructions;
- and
- sending the storage delta packets to a service co-processor maintaining a service address space.
A method for providing service address space, comprising:
- providing a service co-processor attached to a main processor, wherein the service co-processor has a service address space, wherein the main processor is provided with a main address space, wherein the service co-processor creates and maintains an independent copy of the main address space in the form of the service address space;
- updating the service address space by receiving storage delta packets from the main processor and applying the storage delta packets to the service address space;
- and
- performing diagnostic services by the service co-processor based on command packets received from the main processor.
