Changes and New Features
Info
To generate PLDM packages for firmware updates, users must install and use the MFT version that corresponds with the respective firmware release.
| Feature/Change | Description |
| 40.44.1036 | |
| Static Split 8x100G ConnectX-8 to Spectrum-4 with SM Modules | A static split of 8x100G channels from a ConnectX-8 SuperNIC to a Spectrum-4 switch allows the system to use Single Mode (SM) optical modules for high-speed data transmission across a long-distance fibber link. This setup is typically used in high-performance networks where there is a need for high throughput (e.g., 800G in total bandwidth) with low latency, such as in data centers or high-performance computing environments. |
| DOCA Telemetry | DOCA Telemetry enables users to monitor and collect data related to the performance, health, and behavior of systems or applications running on DOCA. To optimize for a faster sampling period, it is recommended to configure all PCIe-related Diagnostic Data IDs sequentially, one after another to prevent a prolonged sampling period. |
| PCIe Switch fwreset | Added support for a new synchronized flow, including a tool and driver, to perform a fwreset on setups with a PCIe switch configuration. |
| PTP | Unified PTP is now supported across different VFs on the same PF. |
| Dual-Mode Temperature Compensated Crystal Oscillator (DC-TCXO) and Synchronous Ethernet (SyncE) Source | DC-TCXO is used now as the source of timing for SyncE, providing an accurate and stable clock for the synchronized operation of network devices that rely on Ethernet for timing. |
| DPA Application Signing | Allows DOCA applications signed with OEM/NVIDIA certificate private keys to be loaded onto the DPA engine, after the OEM/NVIDIA root certificates are installed on the NIC. |
| Data-Path Accelerator (DPA) | The DPA hardware version is now exposed as a new capability, labeled "dpa_platform_version." |
| Block SMP Traffic | Added a new NV config (SM_DISABLE, default 0) which, when enabled, blocks SMP traffic that does not originate from the SM. |
| Dynamic Long Cables | Added the ability to set cable length as a parameter in the PFCC access register. The cable length is used in the calculation of RX lossless buffer parameters, including size, Xoff, and Xon thresholds. |
