DMA channel(在kernel中由“struct dma_chan”数据结构表示)由provider提供,被consumer使用。 consumer可以通过如下的API申请DMA channel: structdma_chan*dma_request_chan(structdevice*dev,constchar*name); 该API是在linux-4.5版本时加入的,在此之前使用的API是dma_request_channel(mask, x, y) 该API会...
However, if there is a low-priority channel already active and is in the middle of a large transfer, a pending higher-priority channel cannot become active. This can hold the execution of a higher-priority channel. This can be a problem when the higher-priority channel caters to a data tr...
Not all DMA engine drivers can return reliable information for a running DMA channel. It is recommended that DMA engine users pause or stop (via dmaengine_terminate_all) the channel before using this API. 0 comments on commit5a42fb9 Pleasesign into comment....

Allocate DMA resources for the object. Use ddi_dmae_prog(9F) to program the system DMA engine to perform the transfer. Perform any required object synchronizations. Use ddi_dmae_stop(9F) to stop the DMA engine. Release the DMA resources. Deallocate the DMA channel.Certain...
