Abstract
The present system enables passing a pointer, associated with accessing data in a memory, to an input/output (I/O) device via an input/output memory management unit (IOMMU). The I/O device accesses the data in the memory via the IOMMU without copying the data into a local I/O device memory. The I/O device can perform an operation on the data in the memory based on the pointer, such that I/O device accesses the memory without expensive copies.
