Changes and New Features

Info

For an archive of changes and features from previous releases, refer to Release Notes Change Log History.

Info

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

    Note

    Allocating 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

    Info

    DDR speed default remains 5200Mhz to maintain backward compatibility.

  • Added support to the bfcfg script to dump extra system configuration information. The -l parameter can be used along with -d to 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:
