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. |
