Corundum mqnic for ZCU106 (PCIe host)
Introduction
This design targets the Xilinx ZCU106 FPGA board. The host system of the NIC is an external host computer connected via PCIe.
- FPGA: xczu7ev-ffvc1156-2-e
- PHY: 10G BASE-R PHY IP core and internal GTH transceiver
- RAM: 2 GB DDR4 2400 (256M x64)
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
Configure DIP switches:
- SW6 4-1: on, on, on, on (mode 0b0000, JTAG boot)
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.
