A sample for the Xilinx DMA Subsystem for PCI Express (QDMA) is included in WinDriver starting WinDriver version 14. The DMA subsystem will allocate an intermediate buffer, and use that buffer, when either (a) your driver indicates that your device does not support scatter/gather, or (b) the device your driver supports is not capable of directly accessing all fragments of the user's data buffer (because the device has only 32-bit DMA support and one or more. Once the qdma module is inserted and until any queue is added into the system and FMAP programming is not done, sysfs provides an interface to configure parameters. In reality, it's extremely rare that any peripheral's register is mapped over the 4 GB range, and quite rare that DMA buffers are mapped over the lower 1 GB. Then you’ll need a kernel driver to do the scatter-gather mapping for which you can use the Linux DMA API, which is also not too complicated. DMAEngine client documentation¶.
