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.
