Changes and New Features

1. DOCA Framework New Features and Updates

• DOCA Argus

  • Now provides key GPU metrics without a host tool/agent.

  • Now supports providing different “runtime manifests” for different containers.

  • Can send out data using vector observability tool.

• DOCA Bridge

  • Removes DOCA dependency on DPDK (for customers who do not need DPDK).

• DOCA Ethernet

  • Adds DOCA Ethernet header data-split support.

  • Adds DOCA Ethernet support for inlining data to WQE, improving performance.

• DOCA Management Service (DMS) [TBC*]

  • Adds a DMS-facing DOCA Core API to query native_port_num.*

  • Adds doca_mgmt API support to resolve vhca_id through libdms and CLI.*

  • Updates DMS provisioning flows to use native DMS APIs instead of gNOI.*

• OVS-DOCA

  • OVS-DOCA now supports IPv6 CT.

  • Adds an OVS-DOCA API to disable reset logic in DOCA-CT aging flows.

  • Adds OVS-DOCA support for the B3220SH Storage Controller.

  • Supports DOCA Ethernet for OVS-DOCA datapath.

  • Adds OVS-DOCA API support for configuring floating CPU behavior for PMD threads.

• DOCA Telemetry

  • DOCA Telemetry lib now exposes RTT counters (hardware congestion control counters).

• DOCA VERBs

  • New DOCA Multi-Rail API in DOCA VERBs to support NIC resiliency for VR [2:1] and LB for non-NVIDIA comm libs.

2. DOCA-Host and DOCA Drivers New Features and Updates

• Adaptive-ReTransmission Related Q-Counters - Adaptive-ReTransmission-related Q-counters are now exposed to all function types, rather than being limited to Physical Functions (PFs) only. This allows any function to view and monitor these counters for improved visibility and diagnostics.

• Fast Registration Memory Region (FRMR) Pools to Replace MR Cache - Replaced the MR cache mechanism with the new generic Fast Registration Memory Region (FRMR) pools feature, providing improved control and visibility into driver optimizations for resource creation during memory registration. This enables users to control the pools, including their sizes and aging time, through the user-space RDMA tool in iproute2.

3. BlueField-3 Firmware Changes and New Features

• PCIe In-Band SPDM Attestation - Added capabilities that allow the host to use in-band channels over PCIe to reach the PSC and perform SPDM attestation.
