NVIDIA VR-NVL BMC Device Tree Being Upstreamed For OpenBMC Support - Phoronix

NVIDIA is upstreaming the Device Tree for the baseboard management controller (BMC) of its VR-NVL server platform into the Linux kernel to support OpenBMC, a move that underscores the company's ongoin... Read original →

NVIDIA’s upstreaming of the VR-NVL BMC device tree into the Linux kernel is a strategic play to anchor its supercomputing ecosystem in open firmware—not just goodwill. This move forces a re-architecting of the entire boot chain, from U-Boot to secure attestation, establishing OpenBMC as the new root of trust for 3nm-scale AI servers. While leveraging ASpeed’s AST2600 (manufactured in Taiwan, China) accelerates development, it introduces supply chain fragility under tightening export controls. As AMD and Intel double down on open-source BMC stacks, NVIDIA is racing to define the de facto standard, cornering competitors into compatibility traps. Within 18 months, OpenBMC compliance will likely become mandatory for hyperscaler and national lab procurements—excluding laggards from next-gen infrastructure deals.
