ABSTRACT:
A memory mapping system for use by a port adapter in a computer facilitates access to named data buffers in host memory. The system generally comprises a mechanism that enables the adapter to efficiently translate the data buffer name to physical address locations in host memory without knowledge of the memory management policies of the computer. Specifically, the system includes various data structures and pointers that allow the port adapter to view host memory in "port pages" when accessing memory locations of a named data buffer. The data locations are virtually, but not physically, contiguous and the invention provides efficient identification of the physical addresses of the locations.
