NVIDIA MBF2H516A-CEEO DPU Firmware 24.41.1000

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-2 DPU provides innovative acceleration, security, and efficiency in every host. BlueField-2 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-2 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.

Changes and New Features:

- 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 vDPA virtual queue state change from suspend to ready, and discrete mkey for descriptor. vDPA Live Migration uses these two new capabilities to reduce downtime since vq can go back to ready state for traffic and descriptor-only-mkey can help reduce mkey mapping time.
- Added a new NVConfig option to copy AR bit from the BTH header to the DHCP header.
- Added the option provide field's offset and length in Steering add_action option.
- 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:

 
- Fixed an issue on the customized server with an independent power supply, that led to an assert with ext_synd as 0x8ce5 during a power cycle process for virtio.
- Fixed an issue that caused traffic not to function properly after performing Live Migration with ingress traffic for vDPA over VFE scenario.
- Fixed an issue that caused traffic failure when modifying the VIRTIO_NET_F_MRG_RXBUF bit for the VDPA device during traffic.
- Fixed an issue that resulted in the second mkey index returning even if it was not set in the creation of the virtio q when querying virtio q object.
- Fixed an issue on the customized server with an independent power supply, that led to a non-functional virtio when power cycled the server during stressful traffic. The following error was provided: "DESTROY_GENERAL_OBJECT(0xa03) No done completion".
- Fixed an issue that resulted in traffic loss after performing Live Migration with virtio vq "frozen-ready" feature.

Known Issues:

- PHYless Reset is currently not supported.
- Some pre-OS environments may fail when sensing a hot-plug operation during their boot stage.
- Unexpected system behavior might be observed if the driver is loaded while reset is in progress.
- When tx_port_ts is set to "true", due to a compensation mechanism in the Tx timestamp available in some hardware Rx timestamp errors, a symmetrical error and no clock offset occur when using the timestamps to synchronize the device clock. This might also cause an error while using timestamps for delay measurements (e,g., delay measurements reported by a PTP daemon) and even negative delay measurements in some cases.
- 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.
- Disabling the Relaxed Ordered (RO) capability (relaxed_ordering_read_pci_enabled=0) using the vhca_resource_manager is currently not functional.
- fwreset is currently supported on PCI Gen 4 devices only.
- 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.
- MFS1S50-H003E cable supports only HDR rate when used as a split cable.
- CRC is included in the traffic byte counters as a port byte counter.
- The "max_shaper_rate" configuration query via QEEC mlxreg returns a value translated to hardware granularity.
- GTP encapsulation (flex parser profile 3) is limited to the NIC domain. Encapsulating in the FDB domain will render a 0-size length in GTP header.
- Some pre-OS environments may fail when sensing a hot plug operation during their boot stage.
- Servers do not recover after configuring PCI_SWITCH_EMULATION_NUM_PORT to 32 followed by power cycle.
- Occasionally, when rising a logical link, the link recovery counter is increase by 1.
- When working with 3rd party device (e.g., Paragon) in 25GbE speed, the 25GbE speed must be configured in force mode.
- Forward action for IPoIB is not supported on RX RDMA Flow Table.

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.
