RevisionDateAuthorComments
 1.4  28-Oct-2017  riastradh Add some #includes to make a few more header files compile.
 1.3  11-Dec-2005  christos branches: 1.3.120;
merge ktrace-lwp.
 1.2  19-Jul-2003  thorpej Add immediate value support for dmoverio transactions.
 1.1  02-Aug-2002  thorpej branches: 1.1.2; 1.1.4; 1.1.6; 1.1.12;
dmover(9) -- an interface to hardware-assisted data movers. This allows
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.
