For 2024-08, NVIDIA/libredfish delivers DPU-first boot orchestration across Lenovo, Dell, and HPE with support for multi-DPU configurations, enabling faster provisioning and consistent boot policies across vendors. Key changes include prioritizing DPU as the first netboot option, determining DPU MAC addresses, and allowing the boot interface MAC address to be specified via machine_setup for multi-DPU setups. Enhancements to boot logic include implementing pcie_devices, improving get_boot_options deserialization, and introducing no-DPU notification when no DPU is present. All major vendors now boot from DPU first (except Supermicro), with a version bump to 0.22.1 to reflect zero-DPU support. Dependency updates (reqwest v0.12, hyper v1) and Rust 1.80 alignment (carbide) were completed to future-proof the stack. Integration tests were added to cover Dell Location feature, improving reliability across configurations. These changes reduce provisioning time, improve automation reliability, and enhance cross-vendor consistency in DPU-first boot workflows.
