I need to clarify a technical point.  AVP is not ivshmem; at least not in the strict sense of the term.   We initially started out using ivshmem as-is but then we needed to fork from that in order to add functionality that we needed to better integrate with our solution.  AVP is now a separate Wind River specific extension completely independent of any past ivshmem implementation.  I used the term ivshmem in the documentation to provide context to the reader to understand, by comparison, what type of shared memory model we are using.  I can remove that reference if it leads to confusion or a desire to make direct comparisons with ivshmem.
