QDMA driver comes with a command-line configuration utility called “dma-ctl” to manage the driver. The Xilinx QDMA control tool, dma-ctl is a Command Line utility built along with driver and allows administration of the Xilinx QDMA queues. It can perform the following functions. Query the QDMA functions/devices the driver has bound into
