Haavard Skinnemoen6d4f5872007-11-28 16:21:43 -08009 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

13 DMA Device drivers supported by the configured arch, it may

378 offload receive copy-to-user operations, freeing CPU cycles.

387 This allows the async_tx api to take advantage of offload engines for
388 memcpy, memset, xor, and raid6 p+q operations. If your platform has
