About This Document

NVIDIA® BlueField® DPU family software is a reference Linux distribution based on the Ubuntu Server and the Yocto Poky distribution extended to include DOCA runtime libraries, the Mellanox OFED stack for Arm and a Linux kernel that supports various accelerations for storage, networking, and security. As such, customers can run any Linux-based applications in the BlueField software environment seamlessly.

These pages provide product release notes as well as information that explains the BlueField Software Distribution (BSD) and how to develop and/or customize applications, system software, and file system images for the BlueField platform.

Intended Audience

This product is intended for software developers and DevOps engineers interested in creating and/or customizing software applications and system software for the NVIDIA BlueField DPU platform.

Software Download

To download product software, please refer to the DOCA SDK developer zone.

PKA Driver Design and Implementation Architecture Document

This document provides a description of the design and implementation of the Public Key accelerator (PKA) hardware driver. The driver manages and controls the EIP-154 Public Key Infrastructure Engine, an FIPS 140-3 compliant PKA and operates as a co-processor to offload the processor of the host.
PKA Programming Guide

This document is intended to guide a new crypto application developer or a public key user space driver. It offers programmers the basic information required to code their own PKA-based application for NVIDIA® BlueField® DPU.
