In linux kernel since version 2.6.24 (release Date: 2008-01-24)
DMA engines can do asynchronous data transfers without
involving the host CPU. Currently, this framework can be
used to offload memory copies in the network stack and
RAID operations in the MD driver. This menu only presents
DMA Device drivers supported by the configured arch, it may
be empty in some cases.
