Providing service address space for diagnostics collection

1. A method for providing service address space for diagnostics collection, comprising:

providing a service co-processor with a service address space attached to a main processor, wherein the main processor is provided with a main address space, the service address space and the main address space being a full range of memory available to the respective service co-processor and the main processor, wherein 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 initializing the service address space by copying data from the main address space; and

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.

2. The method of claim 1 , further comprising attaching the service co-processor to the main processor via an instruction pipe and a command pipe.

3. The method of claim 1 , further comprising delegating, by a service delegation component of the main processor, collection of diagnostic data to the co-processor by sending a collection command via the command pipe from the main processor to the service co-processor for collection of data from the service address space.

4. The method of claim 1 , further comprising intercepting, by an instruction intercepting component of the main processor, instructions that modify the main address space.

5. The method of claim 1 , further comprising generating, by a storage delta packet generator of the main processor, the storage delta packets.

6. The method of claim 1 , further comprising:

queuing the storage delta packets in an instruction pipe from the main processor to the service co-processor such that the service co-processor runs behind the main processor; and

wherein the service address space contains a historical copy of the main address space.
