NixOS runs well on the Visionfive 2 with the current nixos-hardware module https://github.com/NixOS/nixos-hardware/tree/master/starfive/visionfive/v2 (used in the example below); this module bundles an older StarFive custom Linux kernel https://github.com/starfive-tech/linux and its custom firmware for the time being. | NixOS runs well on the Visionfive 2 with the current <code>nixos-hardware</code> module https://github.com/NixOS/nixos-hardware/tree/master/starfive/visionfive/v2 (used in the example below); this module bundles an older StarFive custom Linux kernel https://github.com/starfive-tech/linux and its custom firmware for the time being. | ||
However, this setup needs to be '''updated, build and tested separately''' from the other NixOS Linux kernel variations, '''which is a large, unmaintainable burden for the NixOS community''' when the VisionFive 2 board is not the only supported SoC; so we don't want that. | However, this setup needs to be '''updated, build and tested separately''' from the other NixOS Linux kernel variations, '''which is a large, unmaintainable burden for the NixOS community''' when the VisionFive 2 board is not the only supported SoC; so we don't want that. | ||

Luckily, the Visionfive 2 developers have pushed their Linux kernel patches quite early to the upstream mainline kernel and have gotten almost all merged already. | Luckily, the Visionfive 2 developers have pushed their Linux kernel patches quite early to the upstream mainline kernel and have gotten almost all merged already. | ||

NixOS (more precisely nixpkgs) already has the generic '''Linux kernel 6.9 available, which supports almost everything you need out of the box''' (for a server as HDMI display patches haven't been merged into 6.9). This means NixOS should be able to run without a custom kernel once https://github.com/NixOS/nixos-hardware/pull/958 is merged. | NixOS (more precisely nixpkgs) already has the generic '''Linux kernel 6.9 available, which supports almost everything you need out of the box''' (for a server as HDMI display patches haven't been merged into 6.9).

Also the NixOS version of the popular boot-loader [https://github.com/u-boot/u-boot U-Boot], used by this board, has already received all required patches to fully support this board out-of-the-box. | |||
