Change Description |
|
Hybrid Mode for Hardware DCS Offload |
Added support for hardware DCS offload in hybrid mode, which combines existing software DCS with hardware DCS offload. To enable this feature, set |
|
GGA Transport for High-Speed Data Transfer |
Added support for GGA transport, a high-speed DMA copy engine that enables efficient data transfer between host memory and the DPU's internal memory. |
|
Multi-Node NVLink with Optimized Protocol Selection |
Added support for multi-node NVLink, with automatic detection and selection of the most efficient data transfer protocols. |
|
IP Address Filtering for RoCE Devices |
Added support for filtering RoCE devices based on their IP address, allowing the selection of specific network subnets. To configure the filter, set |
|
Automatic Selection of GPU Bounce Buffers for Large Message Transfers |
Added support for an optimization that automatically selects GPU bounce buffers for large message transfers when these buffers offer performance benefits over host memory buffers. |
|
Single Memory Key Creation Using ODP for Enhanced Efficiency |
Added support for a feature that leverages the ODP capability to create a single memory key for the entire process's virtual address space. This reduces the number of allocated memory keys, helping to bypass firmware limitations. To enable this feature, set |
