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 enables the use of DMA engines in the network stack to
|
|
offload receive copy-to-user operations, freeing CPU cycles.
|
|
Since this is the main user of the DMA engine, it should be enabled;
|
|
say Y here.
