Abstract: Examples described herein relate to at least one processor and circuitry, when operational, to: in connection with a request from a device to copy data to a destination memory address: based on a page fault, copy the data to a backup page and after determination of a virtual-to-physical address translation, copy the data from the backup page to a destination page identified by the physical address. In some examples, the copy the data to a backup page is based on a page fault and an indication that a target buffer for the data is at or above a threshold level of fullness. In some examples, copying the data to a backup page includes: receive the physical address of the backup page from the device and copy data from the device to the backup page based on identification of the backup page.
