clients to use a hardware-assisted data mover to clear a region of memory, fill a region of memory with a specific value, copy a region of memory, and perform simple boolean operations such as XOR on multiple regions of memory. Included here is a software back-end which can serve as an example of how to write a back-end (and also provides a fall-back in case hardware for a given function is not available), as well as a dmoverio(4) pseudo- device which provides access to dmover(9) to userland via a message passing interface. dmover(9) is still a work-in-progress -- a few minor changes to the interface are expected.
