Corundum mqnic for fb4CGg3@VU09P

Introduction

This design targets the Silicom fb4CGg3@VU09P FPGA board.

• FPGA: xcvu9p-flgb2104-2-e
• PHY: 25G BASE-R PHY IP core and internal GTY transceiver
• RAM: 16GB DDR4 2666 (4x 512M x72)

Quick start

Build FPGA bitstream

Run make in the fpga subdirectory to build the bitstream. Ensure that the Xilinx Vivado toolchain components are in PATH.

Build driver and userspace tools

On the host system, run make in modules/mqnic to build the driver. Ensure the headers for the running kernel are installed, otherwise the driver cannot be compiled. Then, run make in utils to build the userspace tools.

Testing

Run make program to program the board with Vivado. Then, reboot the machine to re-enumerate the PCIe bus. Finally, load the driver on the host system with insmod mqnic.ko. Check dmesg for output from driver initialization, and run mqnic-dump -d /dev/mqnic0 to dump the internal state.
