Class

IODeviceMemory

An IOMemoryDescriptor used for device physical memory ranges.

Declaration

class IODeviceMemory : IOMemoryDescriptor

Overview

The IODeviceMemory class is a simple subclass of IOMemoryDescriptor that uses its methods to describe a single range of physical memory on a device. IODeviceMemory objects are usually looked up with IOService or IOPCIDevice accessors, and are created by memory-mapped bus families. IODeviceMemory implements only some factory methods in addition to the methods of IOMemoryDescriptor.
