NVIDIA MCX755206AS-NEA-N SmartNIC Firmware 28.36.2050

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.

The ConnectX-7 smart host channel adapter (HCA), featuring the NVIDIA Quantum-2 InfiniBand architecture, provides the highest networking performance available to take on the world’s most challenging workloads. ConnectX-7 provides ultra-low latency, 400Gb/s throughput, and innovative NVIDIA In-Network Computing acceleration engines to provide additional acceleration to deliver the scalability and feature-rich technology needed for supercomputers, artificial intelligence, and hyperscale cloud data centers.

Changes and New Features:

- Added support for surprise link down mechanism by the DPC.
- Added support for mlxfwreset (multi ASIC reset). Following the mlxfwreset activation, the host reboot will trigger all ASICs' reset (enables applying TLVs, loading new firmware ver).
- Added Get PCIe Error Counters OEM NC-SI command to retrieve PCIe error counters via OOB. Fields that are not supported in Advanced Error Reporting, are reported as 0. Note: Root Error Command, Root Error Status & Error Source Identifier and TLP Prefix Log are currently not supported.
- Added support for MMS4X00-NS-FLT vs T-DP4CNT-N00 HW rev 1A. Note: The recommended cable firmware version: 234.241.0. When connecting the DR8 to the DR4, you must use this specific DR4.
- Added support for ASICs voltage monitoring from each of the MP2975 – DUAL-LOOP DIGITAL PWM CONTROLLER devices.

Implemented the following NC-SI commands:
- Get Protection Options (Command = 0x0, parameter 0x33). This command is issued for the specific package. This Command is used by the BMC to query which protections is enforced on the network controller. On multi-Host platforms this command can only be issued by the chassis manager BMC. The settings of Get Protection Options command are non-volatile.
- Set Protection Options (Command = 0x1, parameter 0x33). This command is issued for the specific package. This Command is used by the BMC to configure which protections shall be enforced on the network controller. On multi-Host platforms this command can only be issued by the chassis manager BMC. The settings of Set Protection Options command are non-volatile.

Implemented the following NVIDIA NC-SI OEM Commands:
- Get Electrical Sensor Count (command 0x13, parameter 0x6)
- Gel Electrical Sensor (command 0x13, parameter 0x7)
- Get Electrical Sensors (command 0x13, parameter 0x8)

Bug Fixes:

- Fixed a wrong DPC flow behavior that occurred due to a PCIe link being down on the downstream port in the PCIe switch configuration.
- Added the option to clear the DPC registers after warm reboot.
- 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.

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.
