pynfb

Python API for control of the CESNET NDK based FPGA acceleration cards.

This package provides Python bindings (via Cython) over libnfb and the Netcope library, enabling register access, packet transmission (NDP queues), and Ethernet MAC management on NFB/NDK FPGA cards.

Prerequisites

pynfb is a source distribution — it compiles Cython extensions at install time and links against the system-installed libnfb and libfdt shared libraries. The nfb-framework package (providing libnfb, the NFB kernel driver, and the required headers) must be installed first.

Minimum version: pynfb 0.3.0 requires nfb-framework >= 6.28. The pynfb version is independent from the nfb-framework version.

Fedora / RHEL / Oracle Linux (RPM)

Enable the COPR repository and install nfb-framework:

sudo dnf copr enable @CESNET/nfb-framework
sudo dnf install nfb-framework

You also need the development files for building:

sudo dnf install libfdt-devel python3-Cython gcc

Build from source

See the NDK software build instructions for compiling libnfb and the kernel driver from source.

Installation

Once the prerequisites are in place:

pip install nfb

Quick start

import nfb

dev = nfb.open()          # opens /dev/nfb0
comp = dev.comp_open("netcope,my_comp", 0)
comp.write32(0x100, 0xDEADBEEF)
val = comp.read32(0x100)
