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

618 Support for the NVIDIA Tegra210 ADMA controller driver. The
619 DMA controller has multiple DMA channels and is used to service
620 various audio clients in the Tegra210 audio processing engine
621 (APE). This DMA controller transfers data from memory to
622 peripheral and vice versa. It does not support memory to

670 AXI VDMA engine provides high-bandwidth direct memory access
671 between memory and AXI4-Stream video type target
672 peripherals including peripherals which support AXI4-
673 Stream Video Protocol. It has two stream interfaces/
674 channels, Memory Mapped to Stream (MM2S) and Stream to
675 Memory Mapped (S2MM) for the data transfers.
676 AXI CDMA engine provides high-bandwidth direct memory access
677 between a memory-mapped source address and a memory-mapped
678 destination address.
679 AXI DMA engine provides high-bandwidth one dimensional direct
680 memory access between memory and AXI4-Stream target peripherals.
