Introduction

The Xilfpga library provides an interface to the Linux or bare-metal users for configuring the programmable logic (PL) over PCAP from PS. The library is designed for
Zynq® UltraScale+— MPSoC to run on top of Xilinx standalone BSPs. In the most common use case, we expect users to run this library on PMU MicroBlaze
with PMUFW to serve requests from Linux for bitstream programming. 

How to enable

xilfpga library can be found at
