Technical Examples

Provided is a method and apparatus for registering requests to access physical memory in a physical address mapping framework. Specifically, a device can register in the physical address mapping framework before accessing physical memory, thus permitting an operating system to identify the device when it is necessary to relocate pages in physical memory. The physical address mapping framework can be any structure that permits registration. For example, the structure can be a list or a tree. When relocating physical memory, all accesses registered in the physical address mapping framework are restricted. Then, the device is notified to stop accessing physical memory via information stored in the physical address mapping framework. After the relocation, the device is notified to resume accessing physical memory via information stored in the physical address mapping framework.
