Release Notes Change Log History

Added support for new BlueField reset and reboot procedures for loading new firmware and firmware configuration changes which replace previous need for server power cycle

Updated the default operation mode of SuperNICs to NIC mode (from DPU mode). This is relevant to the following SKUs:

• 900-9D3B4-00CC-EA0

• 900-9D3B4-00SC-EA0

• 900-9D3B4-00CV-EA0

• 900-9D3B4-00SV-EA0

• 900-9D3B4-00EN-EA0

• 900-9D3B4-00PN-EA0

• 900-9D3D4-00EN-HA0

• 900-9D3D4-00NN-HA0

  Note

  When upgrading one of these SuperNICs to 2.7.0, if its mode of operation was changed at any point in the past, then the last configured mode of operation will remain unchanged. Otherwise, the SuperNIC will rise in NIC operation mode.

Installing the BFB Bundle now performs NIC firmware update by default

Added ability to install NIC firmware and BMC software in NIC mode in NVIDIA® BlueField®-3.

Software packaging – new BlueField firmware bundle package (bf-fwbundle-<version>.prod.bfb), a smaller image for Day 2 upgrades, without the OS and DOCA runtime. Includes ATF, UEFI, nic-fw, bmc-fw, and eROT only.

Improved BlueField BMC robustness –

• Report LLDP for L2 discovery via Redfish

• Improved BlueField DPU debuggability

Increased support for virtio-net VF devices on BlueField-3 networking platforms to 2K

Reduced power consumption for BlueField NIC mode

RAS

• Report DDR Error to OS, including both single-bit ECC error and UCE error

• Support error injection in processors, memory, and PCIe devices

Updated minimum UEFI password requirements

Included DPU BMC firmware as part of the BFB image

Added virtio-net support for plugging/unplugging parallel devices

Implemented virtio debug enhancements

Added Redfish support for configuring all UEFI secure boot settings (disable, enable, enroll user keys, etc.) at scale, remotely, and securely

For FHHL DPUs, added support for performing PCIe bifurcation configuration via MFT tool

Updated the print of the manufacturing (MFG) setting, MFG_OOB_MAC, displayed by the command bfcfg -d to appear in lower-case to align with standard Linux tools

BFB installation chooses the on-chip NVMe (/dev/nvme0n1) by default for the EFI system partition and Linux rootfs installation and can be overloaded with device=/dev/mmcblk0 in bf.cfg to push together with the BFB.

BlueField-3 tuning update for power and performance

BlueField-3 power-capping and thermal-throttling

Added Linux fsck to boot flow

Log PCIe errors (to RShim log)

Halt uncorrectable double-bit ECC error on DDR

Added support for live migration of VirtIO-net and VirtIO-blk VFs from one VM to another. Requires working with the new vDPA driver.

Enroll new NVIDIA certificates to DPU UEFI database

Added support for NIC mode of operation

Added password protection to change boot parameters in GRUB menu

Added IB support for DOCA runtime and dev environment

Implemented RShim PF interrupts

Virtio-net-controller is split to 2 processes for fast recovery after service restart

Added support for live virtio-net controller upgrade instead of performing a full restart

Expanded BlueField-2 PCIe bus number range to 254 (0-253)

Added a new CAP field, log_max_queue_depth (value can be set to 2K/4K), to indicate the maximal NVMe SQ and CQ sizes supported by firmware. This can be used by NVMe controllers or by non-NVMe drivers which do not rely on NVMe CAP field.

Added ability for the RShim driver to still work when the host is in secure boot mode

Added bfb-info command which provides the breakdown of the software components bundled in the BFB package

Added support for rate limiting VF groups

PXE boot option is enabled automatically and is available for the ConnectX and OOB network interfaces

Added Vendor Class option "BF2Client" in DHCP request for PXE boot to identify card

Updated the "force PXE" functionality to continue to retry PXE boot entries until successful. A configuration called "boot override retry" has been added. With this configured, UEFI does not rebuild the boot entries after all boot options are attempted but loops through the PXE boot options until booting is successful. Once successful, the boot override entry configuration is disabled and would need to be reenabled for future boots.

Added ability to change the CPU clock dynamically according to the temperature and other sensors of the DPU. If the power consumption reaches close to the maximum allowed, the software module decreases the CPU clock rate to ensure that the power consumption does not cross the system limit.

Bug fixes

Added ability to perform warm reboot on BlueField-2 based devices

Added support for DPU BMC with OpenBMC​

Added support for NVIDIA Converged Accelerator (900-21004-0030-000)
