WebAddress space. In computing, an address space defines a range of discrete addresses, each of which may correspond to a network host, peripheral device, disk sector, a memory cell or other logical or physical entity. For software programs to save and retrieve stored data, each datum must have an address where it can be located.

WebThe struct describes a single memory area that covers a contiguous interval in a given address space. Each memory area has certain properties, like permissions, and a set of associated operations [1, P. 310]. You can see the struct: WebIt has an associated address space operation table with handlers to perform operations on the address space like readpage, writepage etc. When the file is mapped into memory the internal data structures (vm_area_struct) are updated to specify that the mapped memory area is a valid one. pcie bridge d3
