Changes and New Features
For an archive of changes and features from previous releases, refer to Release Notes Change Log History.
NVIDIA® BlueField ® DPUs support configuring network ports as either Ethernet only or InfiniBand only .
In the devlink and mlxdevm APIs, added support for setting a maximum number of completion event queues for SFs. Setting I/O completion EQs causes the netdev of the SF to use an equal number of TX and RX channels as I/O completion EQs.
Added the ability to designate a part of BlueField-3's L3 cache as exclusive to NIC
NoteAllocating more exclusive cache to NIC improves networking performance at the expense of applications running on the BlueField-3 Arm OS.
BlueField B3220 DDR speed can be configured to either 5200Mhz or 5600Mhz using the Arm UEFI menu if the hardware revision supports these speeds
InfoDDR speed default remains 5200Mhz to maintain backward compatibility.
Added support to the
bfcfgscript to dump extra system configuration information. The-lparameter can be used along with-dto set the dump level.
The following changes in DOCA 2.9.0 (BSP 4.9.0) and BMC 24.10 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 |
