Corundum mqnic for Alveo U280

Introduction

This design targets the Xilinx Alveo U280 FPGA board.

  • FPGA: xcu280-fsvh2892-2L-e
  • MAC: Xilinx 100G CMAC
  • PHY: 100G CAUI-4 CMAC and internal GTY transceivers
  • RAM: 32 GB DDR4 2400 (2x 2G x72 DIMM)
  • HBM: 8GB HBM2

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.
