Summary:In one example of the present technology, an input/output memory management unit (lOMMU) of a computing device is configured to: receive a prefetch message including a virtual address from a central processing unit (CPU) core of a processor of the computing device; perform a page walk on the virtual address through a page table stored in a main memory of the computing device to obtain a prefetched translation of the virtual address to a physical address; and store the prefetched translation of the virtual address to the physical address in a translation lookaside buffer (TLB) of the lOMMU.
