This returns a cookie can be used to check the progress of DMA engine activity via other DMA engine calls not covered in this document. dmaengine_submit() will not start the DMA operation, it merely adds it to the pending queue. For this, see step 5, dma_async_issue_pending.

Device Drivers -> DMA Engine support -> DMA Test client In the configuration file the option called CONFIG_DMATEST. The dmatest could be built as module or inside kernel. Let’s consider those cases.

This DMA engine which is an PCIe iEP offers 30 channels, each channel has a send queue, a complete queue and an interrupt to help to do tasks. This DMA engine can do memory copy between memory blocks or between memory and device buffer.

DMA can also be used for "memory to memory" copying or moving of data within memory. DMA can offload expensive memory operations, such as large copies or scatter-gather operations, from the CPU to a dedicated DMA engine. An implementation example is the I/O Acceleration Technology.
