10 involving the host CPU. Currently, this framework can be
11 used to offload memory copies in the network stack and
12 RAID operations in the MD driver. This menu only presents
13 DMA Device drivers supported by the configured arch, it may

617 AXI VDMA engine provides high-bandwidth direct memory access
618 between memory and AXI4-Stream video type target
619 peripherals including peripherals which support AXI4-
620 Stream Video Protocol. It has two stream interfaces/
621 channels, Memory Mapped to Stream (MM2S) and Stream to
622 Memory Mapped (S2MM) for the data transfers.
623 AXI CDMA engine provides high-bandwidth direct memory access
624 between a memory-mapped source address and a memory-mapped
625 destination address.

668 This allows the async_tx api to take advantage of offload engines for
669 memcpy, memset, xor, and raid6 p+q operations. If your platform has
670 a dma engine that can perform raid operations and you have enabled
