Abstract
A method for data transfer includes receiving in a data transfer operation data to be written by a peripheral device to a specified virtual address in a random access memory (RAM) of a host computer. Upon receiving the data, it is detected that a page that contains the specified virtual address is marked as not present in a page table of the host computer. The peripheral device receives a notification that the page is not present and an estimate of a length of time that will be required to make the page available and selects a mode for handling of the data transfer operation depending upon the estimate.
