Lenovo legion 7i 16ithg6

[ulrikstrid]

I don't know how to post this correctly, but I have the Legion 7i from 2021 and have packaged it for nixos. From some initial testing everything seems to work, even the battery conservation setting which I've been looking for since switching over to Linux.

If you want more info let me know and I'll post whatever.

Great! Thanks for creating the nixos package. You might want to update it in a month because right now new features are being added and tested.

Can you give me the output of sudo dmidecode -t bios so I can get the BIOS version. Then I can add your model and bios to the list of compatible models.

[johnfanv2]

Is there a website/page for the package, e.g. on https://search.nixos.org? Then we can include a link to the package like the AUR package for arch

I updated the initial issue description with the outputs requested.

When my nixpkgs PR is merged, packaging Linux modules and even Python code is new to me so I've been asking for some thorough reviews, it will be available to search for on https://search.nixos.org as you mention. But the install instructions will be as simple as:
boot.extraModulePackages = [ config.boot.kernelPackages.lenovo-legion-module ];

Great, I added a link to the NixOS packages.
