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 [31mCONFIG_MD[0m driver. This menu only presents
DMA Device drivers supported by the configured arch, it may
be empty in some cases.

help
This allows the async_tx api to take advantage of offload engines for
memcpy, memset, xor, and raid6 p+q operations. If your platform has
a dma engine that can perform raid operations and you have enabled
[31mCONFIG_MD_RAID456[0m say Y.
If unsure, say N.

Simple DMA test client. Say N unless you're debugging a
DMA Device driver.
