# DMA source and sink blocks for Xilinx Zynq FPGAs
The Pothos Zynq support package provides:
* DMA source and sink blocks for zero-copy buffer integration with a Pothos data flow
* a linux kernel module for interfacing with an AXI DMA engine in the programmable logic
* loopback examples in Vivado, Zynq boot files, and documentation to recreate the demo
## Layout
* kernel/ - the Pothos AXI DMA support linux kernel module
* driver/ - the Pothos AXI DMA userspace driver with C API
* blocks/ - Pothos framework DMA source and sink blocks
* loopback_microzed/ - example Vivado loopback project and boot files
## Dependencies
* Pothos library
* Zynq processor running linux
## Building
Configure, build, and install with CMake
## Using DMA blocks
```
insmod pothos_zynq_dma.ko
ls /dev/pothos_zynq_dma*
```
