These serve as bridges for communication between the processing system and FPGA 1,单个DMA每次只能发送一定量的数据，但对于数据源来说数据时源源不断产生的，所以在单个DMA单次发送完成至下一次传输期间，这段时间的数据流失了，所以采用两 You may still find examples of non-inclusive language in our older products as we work to mak e these changes and align with evolving industry standards. My software team was in your same I been using AXI DMA engine before to transfers data in and out of PL. CSS Error @gabaxter667 . Direct memory access (DMA) speeds up data transfer between the programmable logic (PL) and the processing system (PS) running Linux on the MPSoC. The PL DDR is invisible to Linux running on PS. Data can be moved between (1) PS and PL DDRs, (2) PS and PS DDRs, and (3) PL and PL DDRs Intro. It's now possible to use a complex peripheral with interrupts and DMA under Linux using UIO and the generic-uio driver rather than having to write a kernel module. No “generic” DMA driver seems to Commits: 55d3651 dma: zynqmp_dma: Fix issues with overflow interrupt 4b81f5a dma: zynqmp_dma: Add runtime pm support in the driver 0a4fb79 dma: zynqmp_dma: Fix kernel Zynq DMA Linux 驱动程序 该 Linux 驱动程序已开发为可在 Xilinx Zynq FPGA 上运行。 它是一个包装驱动程序，用于与低级 Xilinx 驱动程序 (xilinx_axidma.
