wired memory

A range of memory that the virtual-memory system does not page out or move. The memory involved in an I/O transfer must be wired down to prevent the physical relocation of data being accessed by hardware. In the I/O Kit memory is wired when the memory descriptor describing the memory prepares the memory for I/O (which happens when its prepare method is invoked).
