NVIDIA 900-9D3B6-00SN-A DPU Firmware 32.41.1000

Firmware which is added at the time of manufacturing, is used to run user programs on the device and can be thought of as the software that allows hardware to run. Embedded firmware is used to control the functions of various hardware devices and systems, much like a computer’s operating system (OS) controls the function of software applications. Firmware may be written into read-only memory (ROM), erasable programmable read-only memory (EPROM) or flash memory.

NVIDIA BlueField-3 DPU provides innovative acceleration, security, and efficiency in every host. BlueField-3 data center infrastructure combines the power of the NVIDIA ConnectX-6 Dx with programmable Arm cores and hardware offloads for software-defined storage, networking, security, and management workloads.

NVIDIA BlueField-3 also delivers superior performance, security, and reduced TCO for cloud computing platforms, enabling organizations to efficiently build and operate virtualized, containerized, and bare-metal infrastructures at massive scale.

SuperNIC mode is now the default mode for the following SKUs:

- 900-9D3D4-00EN-HA0
- 900-9D3D4-00NN-HA0

Changes:

- Added support for VIRTIO_NET_F_HASH_REPORT(57) bit for the virtio-net emulation device.
- Added support for VIRTIO_NET_F_SPEED_DUPLEX(63) bit for the virtio-net emulation device.
- Added support for virtio full emulation scale up to 2k devices.
- Added support for the following prefetch fields on ODP event: pre_demand_fault_pages, post_demand_fault_pages.
- Implemented Deterministic Random Bit Generator (DRBG) algorithm on top of firmware TRNG (the source for raw data input) in accordance with NIST SP800-90A.
- Added support for PSP in Hardware Steering.
- Added a new NVConfig option to copy AR bit from the BTH header to the DHCP header.
- Generic Emulation enables the programmers to define their own custom PCI devices to be exposed to the host using the new hot-plug/unplug function flow. The API enables the programmer to control the device BARs layout, software defined BAR registers and hardware offloading mechanisms (MSI-X, DBs).
- Added the option provide field's offset and length in Steering add_action option.
- Added support for steering match on packet l4_type through FTG/FTE.
- RSHIM PF functionalities are now dynamically locked/unlocked during runtime by Platform BMC via the NC-SI commands.
- Added support for 64KB pages.
- Added the ability to query ATF/UEFI version via the MISOC register.
- Added support for PCC NP for RTT according to the IFA2.0 standards.
- Extended Flex Parser merge mechanism to support hardware capabilities.
- Enabled the option to disable the native parser when the parse graph node is configured with the same conditions.
- Added support for father/son headers parsing.
- Added support for tunnel_offload in LRO.

Bug Fixes:

- Added the TX_SCHEDULER_FWS_REACTIVITY nvconfig flag to solved an mlnx_qos ETS settings issue.
- Improved ZTR_RTTCC algorithm fairness when running with 4K MTU.
- Fixed an issue where Congestion Control could malfunction due to an invalid database.
- Enabled NC-SI NVIDIA OEM command Get PF MAC Address accessed inexistent PF MAC when "Hide second port".

Known Issues:

- NC-SI pass-through requires the user to allocate a MAC address to the platform BMC.
- NVIA register is not allowed for external host if any field of EXTERNAL_HOST_PRIV or EXTERNAL_HOST_PRIV_FAST TLVs is not set as the default.
- When configuring BlueField-3 Arm cores as PCIe root-complex, all non-mlx5 devices must always set the BlueField-3’s IOMMU to disabled or passthrough mode. Turning IOMMU “ON” requires special handling of interrupts in the driver or the use of polling. For further assistance, contact NVIDIA support .
- The supported DDR5 link speed in SKU B3220, is 5200 MT/s
- SW_RESET with a pending image is currently not supported.
- Occasionally, the device may hang when there a hot plug is performed from a unknown direction.
- Some pre-OS environments may fail when sensing a hot-plug operation during their boot stage.
- The I2C clock fall time is lower than the 12ns minimum defined in the I2C-bus specification.
- When connecting to a High Speed Traffic Generator in 400G speed, the linkup time may takes up to 3 minutes.
- External flash access such as flash read using the MFT tools will fail if there is a pending image on the flash.
- On BlueField-3 devices, from DOCA 2.2.0 to 32.37.1306 (or lower), the host crashes when executing partial Arm reset (e.g., Arm reboot; BFB push; mlxfwreset).
- When unloading the network drivers on an external host, sync1 reset may be still reported as 'supported' although it is not. Thus, initiating the reset flow may result in reset failure after a few minutes.
- When connecting to a Spirent switch in 400G speed, the linkup time may takes up to 3 minutes.
- PCIe PML1 is disabled.
- Unexpected system behavior might be observed if the driver is loaded while reset is in progress.
- When performing PCIe link secondary-bus-reset, disable/enable or mlxfwreset on AMD based Genoa systems, the device takes longer then expected to link up, due to a PCIe receiver termination misconfiguration.
- The firmware rollback fails for the signature retransmit flow if the QPN field is configured in the mkey (as it only allows the given QP to use this Mkey) as the firmware rollback flow relies on an internal QP that uses the mkey.
- Socket-Direct is currently not supported.

About Network Adapter Drivers:

When connected, the operating system usually installs a generic driver that helps the computer to recognize the newly attached device.

However, proper software must be applied if you want to make use of all features that the network adapter has available. This task also allows computers to properly recognize all device characteristics such as manufacturer, chipset, technology, and others.

Updating the adapter's drivers and utilities version might improve overall performance and stability, increase transfer speeds, fix different compatibility problems and several network-related errors, as well as bring various other changes.

To install this release, simply get the package, extract it if necessary, run the setup, and follow the instructions displayed on-screen. When done, don't forget to perform a system restart and reconnect the network adapter to make sure that all changes take effect properly.

Without further ado, if you intend to apply this version, click the download button and install the package. Moreover, check with our website as often as possible so that you don't miss a single new release.
