Snapdragon is an ARM CPU which means if you can find a distro to run on it, it’ll likely be an Android custom ROM, whereas Celeron is x86 and should run most Linux distros without issue.

The package is just a systemd unit to run the command python zenstates --c6-disable so if you install the zenstates-git package and get runit to run that command at startup it would be equivalent.

I have a system with a Ryzen 1700 with the same issue and have found the only reliable way to run it is by installing and enabling the disable-c6-systemd package from the AUR. The other fixes provided in the wiki article you linked are correct but aren’t sufficient on my system, the CPU keeps reenabling the C6 state on its own and the disable-c6-systemd package works to counter that. The reason it works on Windows is they’ve disabled the C6 state by default for the CPU.

Same here. I came for the integrated ZFS support and stayed for the declarative config.

I’ve had VFIO passthrough setup on a NixOS host before without issue. While this guide isn’t the one I followed it is an accurate and good guide.

I really enjoy using NixOS as it is good at what it does, declarative system configuration, but it does have issues that can prevent people from using it. It’s great if you want to put the configuration for all your computers in one git repo but that configuration is in the Nix language so you will eventually need to become familiar with the Nix language. The main issues are that the documentation needs work and understanding the difference between the Nix operating system, the Nix language, and the Nix package collection as the more you use NixOS the more familiar you will need to be with each.

That said, I find it worth learning and recommend some of the following resources for NixOS.

MyNixOS for graphical configuration management. See my configs there.

NixOS Wiki for the best collection of NixOS documentation. I’ve found this collection of people’s configurations to be very useful for inspiration.

The manual pages for the Nix language, Nix packages, and NixOS.

NixOS on everything but my Steam Deck which is running SteamOS.
