NVIDIA® BlueField ® DPUs support configuring network ports as either Ethernet only or InfiniBand only .
PLDM firmware update support for BlueField-3 devices
Added support for PLDM firmware update – BlueField-3 devices now support firmware updates via the PLDM type-5 protocol over MCTP over PCIe, allowing future updates to be performed through the platform's BMC. This implementation complies with PLDM specification version 1.0. Note that the firmware image size is approximately 100MB.
Known limitations:
With this release, firmware updates using the PLDM flow can only be applied with a full-system power cycle. Support for applying updates via server reboot will be added in a future release.
When operating in DPU mode, administrators must manually configure BMC credentials in a local Arm OS config file to enable BMC and CEC updates. Provisioning of credentials will be automated in a future release.
Enhanced firmware reset flow for Sync1 utilizing community-accepted hot reset kernel flow
Added logging of NVMe/eMMC wipe operations to RShim log
Bug fixes
The following changes in DOCA 2.9.1 (BSP 4.9.1) and BMC 24.10-LTSU1 break backward compatibility and therefore require customers to upgrade all DOCA software components to the latest available version to avoid anomalous behavior:
Software Component | Change Description |
BMC | IPMB channel relocation – The IPMB channel used by the BlueField BMC to retrieve data from the BlueField Arm is now utilizing a dedicated I2C interface. This change is aimed at improving the serviceability of the interface. |
FlexIO | Fixing a mandatory hardware limitation found the updated firmware version breaks backward compatibility between the software layers |
