IOMemoryDescriptor
Abstract: An abstract base class defining common methods for describing physical or virtual memory.
The IOMemoryDescriptor object represents a buffer or range of memory, specified as one or more physical or virtual address ranges. It contains methods to return the memory's physically contiguous segments (fragments), for use with the IOMemoryCursor, and methods to map the memory into any address space with caching and placed mapping options.
