Release Notes Change Log History

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)
