9 | DMA engines can do asynchronous data transfers without |
10 | involving the host CPU. Currently, this framework can be | |
11 | used to offload memory copies in the network stack and | |
9c402f4e DW |
12 | RAID operations in the MD driver. This menu only presents |
13 | DMA Device drivers supported by the configured arch, it may | |
