Installing Prerequisites on Host for Target BlueField

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

Determining BlueField Device ID

It is important to learn your BlueField's device-id for performing some of the software installations or upgrades in this guide.

To determine the device ID of the DPUs and SuperNICs 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
 
BlueField3(rev:1)       /dev/mst/mt41692_pciconf0     e2:00.0   mlx5_0          net-ens7f0np0             4
        

The device IDs for the BlueField-2 and BlueField-3 networking platforms in this example are /dev/mst/mt41686_pciconf0 and /dev/mst/mt41692_pciconf0 respectively.

   Copied!

               
   
               
   host# sudo /etc/init.d/openibd restart
           

3. Initialize MST. Run:

   Copy

   Copied!

               
   
               
   host# sudo mst start
           

4. Reset the nvconfig parameters 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 BlueField's device ID, refer to section "Determining Bluefield Device ID".

5. Skip this step if your BlueField DPU or SuperNIC is Ethernet only. Please refer to Supported Platforms to learn your Bluefield type.

   If you have a VPI networking platform, 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
   Configurations:                              Default         Current         Next Boot
   *        LINK_TYPE_P1                        IB(1)           ETH(2)          IB(1)
   *        LINK_TYPE_P2                        IB(1)           ETH(2)          IB(1)
           

   Note

   If your BlueField 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
           

6. Verify that RShim is active.

   Copy

   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
           

7. 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
           

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:

  1. Run:

     Copy

     Copied!

                 
     
                 
     host# sudo apt install -y doca-tools doca-extra
             

  2. 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.

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.

Installing Full DOCA Image on DPU via Host

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 Bluefield. You may run the following command to verify:

            

            
host# ls -la /dev/ | grep rshim
        

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:

1. Create password hash. Run:

   Copy

   Copied!

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

2. 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

Installing Full DOCA Image on Multiple Networking Platforms

On a host with multiple networking platforms, the BFB image can be installed on all of them using the multi-bfb-install script.

            

            
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/RH 8.0 and 8.2 – the script installs the bridge-utils package to use the brctl command, creates the tm-br bridge, 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 tm-br bridge 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 BlueField and configures a new IP, 192.168.100.x, as described earlier.

Installing DOCA Local Repo Package on BlueField

1. Download the DOCA SDK, DOCA Runtime, and DOCA Tools package from section Installation Files.

2. Copy deb repo package into BlueField. Run:

   Copy

   Copied!

               
   
               
   host# sudo scp -r doca-repo-aarch64-ubuntu2204-local_<version>_arm64.deb ubuntu@192.168.100.2:/tmp/
           

3. Unpack the deb repo. Run:

   Copy

   Copied!

               
   
               
   dpu# sudo dpkg -i doca-dpu-repo-ubuntu2204-local_<version>_arm64.deb
           

4. Run apt update.

   Copy

   Copied!

               
   
               
   dpu# sudo apt-get update
           

5. Run apt install for DOCA Runtime, DOCA Tools, and DOCA SDK:

   Copy

   Copied!

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

Upgrading Firmware

To upgrade firmware:

1. SSH to your BlueField device via 192.168.100.2 (preconfigured).

   Note

   If multiple BlueField's 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	Password
   ubuntu	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>
           

2. Upgrade firmware in BlueField networking platform. Run:

   Copy

   Copied!

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

   Example output:

   Copy

   Copied!

               
   
               
   Device #1:
   ----------
    
     Device Type:      BlueField-2
     [...]
     Versions:         Current        Available
        FW             <Old_FW>       <New_FW>
           

3. For the firmware upgrade to take effect:

   1. Run the following command on BlueField and host:

      Copy

      Copied!

                  
      
                  
      dpu# sudo mst start
              

   2. Otherwise, trigger reset by running the following:

      Copy

      Copied!

                  
      
                  
      dpu# sudo mlxfwreset -d /dev/mst/mt41686_pciconf0 --sync 1 -y reset
              

      If the mlxfwreset command fails, perform host power cycle.

      Note

      The entire BlueField networking platform will experience reset.

Users wishing to build their own customized BlueField OS image can use the BFB build environment. Please refer to the bfb-build project in this GitHub webpage for more information.

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

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 11.8.0.

Configuring Operation Mode

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

• Standard mode (default) – the BlueField networking platform and the GPU operate separately

• BlueField-X mode – the GPU is exposed to BlueField 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:

  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. For power cycle the host run:

            

            
host# ipmitool power cycle
