NVIDIA's latest Linux kernel mailing list patches are for providing the Device Tree for the baseboard management controller (BMC) of their Vera Rubin VR-NVL server platform. With the Linux kernel patches and also for U-Boot, it's part of the upstreaming effort for supporting the open-source OpenBMC software on their latest hardware.

Sent out today on the Linux kernel mailing list is their 901 line Device Tree file for the VR-NVL BMC. NVIDIA VR-NVL is for the Vera Rubin NVL72 rack-scale supercomputer. The NVIDIA VR-NVL BMC is making use of an ASpeed AST2600-based controller.

[1]This patch series provides that DT for the Linux kernel community. Similarly is [2]another patch for the UBoot/OpenBMC side.

Great seeing all the continued industry interest around [3]OpenBMC . Back when I was at NVIDIA for the [4]Vera CPU benchmarking , executives affirmed there being customer interest in the likes of OpenBMC and other open-source firmware related topics, just as it's increasingly been among hyperscalers for AMD and Intel servers too largely in the name of security reasons and transparency/adaptability.
