Linux Installation Guide

NVIDIA DOCA Installation Guide for Linux

This document details the necessary steps to set up NVIDIA DOCA in your Linux environment.

There are two ways to install the NVIDIA® BlueField® DPU software:

• Using the SDK Manager which provides a GUI/CLI for full DPU software installation
• Manual installation with a step-by-step procedure

1.1. Supported Platforms

DOCA is supported on the devices listed in the following subsections.

1.1.1. Supported BlueField DPUs

The following BlueField DPUs are supported with DOCA 2.2.0:

1.1.2. Supported ConnectX NICs

The following NVIDIA® ConnectX® NICs are supported with DOCA on the host:

• ConnectX-7 devices
• ConnectX-6 Dx devices
• ConnectX-6 Lx devices
• ConenctX-6 device

1.2. Hardware Prerequisites

This quick start guide assumes that an NVIDIA® BlueField® DPU has been installed in a server according to the instructions detailed in your DPU's hardware user guide.

1.3. DOCA Packages

1.4. Supported Operating System Distributions

The default operating system of the BlueField DPU (Arm) is Ubuntu 22.04.

The supported operating systems on the host machine are the following:

NVIDIA SDK Manager (SDKM) supports DOCA installation, including software packages on the host and the BlueField target. The SDKM automates the process of DOCA installation and other related configuration of the system.

• To use the SDK Manager CLI (recommended), please refer to NVIDIA SDK Manager CLI installation guide for DOCA for detailed instructions.
• To use the SDK Manager GUI, please refer to NVIDIA SDK Manager GUI installation guide for DOCA for detailed instructions.

The following example uses the SDKM CLI to install DOCA without any additional SDKs:

            

            
host# sdkmanager --cli install --logintype devzone --product DOCA --version 2.2.0 --targetos Linux --host --target BLUEFIELD2_DPU_TARGETS --flash all
        

This guide provides the minimal first-step instructions for setting up DOCA on a standard system.

3.1. Installation Files

3.2. Uninstalling Software from Host

If an older DOCA or MLNX_OFED software version is installed on your host, make sure to uninstall it before proceeding with the installation of the new version:

            

            
$ for f in $( dpkg --list | grep doca | awk '{print $2}' ); do echo $f ; apt remove --purge $f -y ; done
$ ofed_uninstall.sh --force
$ sudo apt-get autoremove
        

            

            
host# for f in $(rpm -qa |grep -i doca ) ; do yum -y remove $f; done
host# ofed_uninstall.sh --force
host# yum autoremove
host# yum makecache
        

Then perform the following procedure:

3.3. Installing Prerequisites on Host for Target DPU

Install doca-tools to manage and flash the BlueField DPU.

3.4. Determining DPU Device ID

It is is important to learn your DPU's device-id for performing some of the software installations or upgrades in this guide. To determine the device ID of the DPUs on your setup, run:

            

            
host# mst start
host# mst status -v
        

Example output:

            

            
MST modules:
------------
    MST PCI module is not loaded
    MST PCI configuration module loaded
PCI devices:
------------
DEVICE_TYPE             MST                           PCI       RDMA            NET                       NUMA
BlueField2(rev:1)       /dev/mst/mt41686_pciconf0.1   3b:00.1   mlx5_1          net-ens1f1                0
  
BlueField2(rev:1)       /dev/mst/mt41686_pciconf0     3b:00.0   mlx5_0          net-ens1f0                0
 
BlueField3(rev:1)       /dev/mst/mt41692_pciconf0.1   e2:00.1   mlx5_1          net-ens7f1np1             4

   host# sudo mst start
           

5. Reset the nvconfig params to their default values:
   
   Copy

   Copied!

               
   
               
   host# sudo mlxconfig -d <device-id> -y reset
   
   Reset configuration for device <device-id>? (y/n) [n] : y
   Applying... Done!
   -I- Please reboot machine to load new configurations.
           

   Note:

   To learn the DPU's device ID, refer to Determining DPU Device ID.

6. Skip this step if your BlueField DPU is Ethernet only. Please refer to Supported Platforms to learn your DPU type. If you have a VPI DPU, the default link type of the ports will be configured to IB. To verify your link type, run:
   
   Copy

   Copied!

               
   
               
   host# sudo mst start
   host# sudo mlxconfig -d <device-id> -e q | grep -i link_type

   Note:

   If your DPU is Ethernet capable only, then the sudo mlxconfig -d <device> command will not provide an output.

   If the current link type is set to IB, run the following command to change it to Ethernet:
   
   Copy

   Copied!

               
   
               
   host# sudo mlxconfig -d <device-id> s LINK_TYPE_P1=2 LINK_TYPE_P2=2

   Copied!

               
   
               
   host# sudo systemctl status rshim
           

   This command is expected to display active (running). If RShim service does not launch automatically, run:
   
   Copy

   Copied!

               
   
               
   host# sudo systemctl enable rshim
   host# sudo systemctl start rshim
           

8. Assign a dynamic IP to tmfifo_net0 interface (RShim host interface).
   
   Note:

   Skip this step if you are installing the DOCA image on multiple DPUs.

   Copy

   Copied!

               
   
               
   host# ifconfig tmfifo_net0 192.168.100.1 netmask 255.255.255.252 up
           

3.5.1. DOCA Extra Package

If the kernel version on on your host is not supported (not shown under "Supported Operating System Distributions"), two options are available:

• Switch to a compatible kernel
• Install doca-extra package
  
  2. Run:
     
     Copy

     Copied!

                 
     
                 
     host# sudo apt install -y doca-extra
             

  3. Execute the doca-kernel-support script which downloads the appropriate missing packages from your kernel to support DOCA:
     
     Copy

     Copied!

                 
     
                 
     host# sudo /opt/mellanox/doca/tools/doca-kernel-support
             

     Note:

     doca-kernel-support does not support customized or unofficial kernels.

3.6. Installing Software on DPU

Users have two options for installing DOCA on the DPU:

• Upgrading the full DOCA image on the DPU (recommended) - this option overwrites the entire boot partition.
• Upgrading DOCA local repo package on the DPU – this option upgrades DOCA components without overwriting the boot partition. Use this option to preserve configurations or files on the DPU itself.

3.6.1. Installing Full DOCA Image on DPU

3.6.1.1. Option 1 - No Pre-defined Password

BFB installation is executed as follows:

            

            
host# sudo bfb-install --rshim <rshimN> --bfb <image_path.bfb>
        

Where rshimN is rshim0 if you only have one DPU. You may run the following command to verify:

            

            
host# ls -la /dev/ | grep rshim
        

3.6.1.2. Option 2 - Set Pre-defined Password

Ubuntu users can provide a unique password that will be applied at the end of the BlueField software image installation. This password needs to be defined in a bf.cfg configuration file. To set the password for the "ubuntu" user:

2. Create password hash. Run:
   
   Copy

   Copied!

               
   
               
   host# openssl passwd -1
   Password:
   Verifying - Password:
   $1$3B0RIrfX$TlHry93NFUJzg3Nya00rE1
           

3. Add the password hash in quotes to the bf.cfg file:

   Copy

   Copied!

               
   
               
   host# sudo vim bf.cfg
   ubuntu_PASSWORD='$1$3B0RIrfX$TlHry93NFUJzg3Nya00rE1'
           

   When running the installation command, use the --config flag to provide the file containing the password:

   Copy

   Copied!

               
   
               
   host# sudo bfb-install --rshim <rshimN> --bfb <image_path.bfb> --config bf.cfg
           

   Note:

   If --config is not used, then upon first login to the BlueField device, users will be asked to update their password.

   The following is an example of Ubuntu installation assuming the "pv" Linux tool has been installed (to view the installation progress).

   Copy

   Copied!

               
   
               
   host# sudo bfb-install --rshim rshim0 --bfb DOCA_<version>-aarch64.bfb --config bf.cfg

3.6.2. Installing Full DOCA Image on Multiple DPUs

On a host with multiple DPUs, the BFB image can be installed on all of them using the multi-bfb-installscript.

            

            
host# ./multi-bfb-install --bfb <bfb-file> --password <password>
        

This script detects the number of RShim devices and configures them statically.

• For Ubuntu – the script creates a configuration file /etc/netplan/20-tmfifo.yaml
• For CentOS/RHEL 7.6 – the script creates a configuration file /etc/sysconfig/network-scripts/ifcfg-br_tmfifo
• For CentOS/RHEL 8.0 and 8.2 – the script installs bridge-utils package to use the command brctl, creates bridge tm-br and connects all RShim interfaces to it

After the installation is complete, the configuration of the bridge and each RShim interface can be observed using ifconfig. The expected result is to see the IP on the bridge tm-br configured to 192.168.100.1 with subnet 255.255.255.0.

            

            
ssh ubuntu@192.168.100.2
        

The script burns a new MAC address to each DPU and configures a new IP, 192.168.100.x, as described earlier.

3.6.3. Installing DOCA Local Repo Package on DPU

2. Download the DOCA SDK, DOCA Runtime, and DOCA Tools package from section Installation Files.
3. Copy deb repo package into BlueField. Run:
   
   Copy

   Copied!

               
   
               
   host# sudo scp -r doca-repo-aarch64-ubuntu2004-local_<version>_arm64.deb ubuntu@192.168.100.2:/tmp/
           

4. Unpack the deb repo. Run:
   
   Copy

   Copied!

               
   
               
   dpu# sudo dpkg -i doca-dpu-repo-ubuntu2004-local_<version>_arm64.deb
           

5. Run apt update:
   
   Copy

   Copied!

               
   
               
   dpu# sudo apt-get update
           

6. Check for any DOCA package content upgrade. Run:
   
   Copy

   Copied!

               
   
               
   dpu# sudo apt install doca-runtime
   dpu# sudo apt install doca-tools
   dpu# sudo apt install doca-sdk
           

3.7. Upgrading Firmware

To upgrade firmware:

2. SSH to your BlueField device via 192.168.100.2 (preconfigured).
   
   Note:

   If multiple DPUs are installed, the tmfifo IP interface does not have to be 192.168.100.2. The last octate changes and depends on the RShim number.

   The default credentials for Ubuntu are as follows:
   
   • Username: ubuntu
   • Password: ubuntu or a unique password that you set in bf.cfg

   For example:

   Copy

   Copied!

               
   
               
   host# ssh ubuntu@192.168.100.2 Password: <configured-password>
           

3. Upgrade firmware in BlueField DPU. Run:
   
   Copy

   Copied!

               
   
               
   dpu# sudo /opt/mellanox/mlnx-fw-updater/mlnx_fw_updater.pl --force-fw-update
           

   Example output:
   
   Copy

   Copied!

               
   
               
   Device #1:

For full instructions about setting up a development environment, refer to the NVIDIA DOCA Developer Guide.

6.1. Installing CUDA on NVIDIA Converged Accelerator

NVIDIA® CUDA® is a parallel computing platform and programming model developed by NVIDIA for general computing GPUs.

This section details the necessary steps to set up CUDA on your environment. This section assumes that a BFB image has already been installed on your environment. To install CUDA on your converged accelerator:

1. Download and install the latest NVIDIA Data Center GPU driver.
2. Download and install CUDA.
   Note:

   The CUDA version tested to work with DOCA SDK is 12.1.

6.1.1. Configuring Operation Mode

There are two modes that the NVIDIA Converged Accelerator may operate in:

• Standard mode (default) – the BlueField DPU and the GPU operate separately
• BlueField-X mode – the GPU is exposed to the DPU and is no longer visible on the host

To verify which mode the system is operating in, run:

            

            
host# sudo mst start
host# sudo mlxconfig -d <device-id> q PCI_DOWNSTREAM_PORT_OWNER[4]
        

• Standard mode output:
  Copy

  Copied!

              
  
              
  Device #1:
  […]
  Configurations:                              Next Boot
           PCI_DOWNSTREAM_PORT_OWNER[4]        DEVICE_DEFAULT(0)
          

• BlueField-X mode output:
  Copy

  Copied!

              
  
              
  Device #1:
          […]
          Configurations:                              Next Boot
          PCI_DOWNSTREAM_PORT_OWNER[4]        EMBEDDED_CPU(15)
          

To configure BlueField-X mode, run:

            

            
host# mlxconfig -d <device-id> s PCI_DOWNSTREAM_PORT_OWNER[4]=0xF
        

To configure standard mode, run:

            

            
host# mlxconfig -d <device-id> s PCI_DOWNSTREAM_PORT_OWNER[4]=0x0
        

Power cycle is required for configuration to take effect. To power cycle the host run:

            

            
host# ipmitool power cycle
        

6.1.2. Downloading and Installing CUDA Toolkit and Driver
