Detailed Description
This wraps an implementation of DPM primitives.
Each interface provider supplies a structure like this, which is the glue between upper level code and the lower level hardware access.
It is a PRELIMINARY AND INCOMPLETE set of primitives, starting with support for CPU register access.
