@rake5k Have you got a working config for this? If not I'm working on it.

[rake5k]

Not at all, thank you a lot for looking into it! But I am glad to help out with testing if it would help. On Thursday, December 7th, 2023 at 23:00, Phil A Thompson @.***> wrote:

I've never packaged anything in NixOS before (only been using it for a couple of months) but I managed to get a derivation working locally. Tested with fftest (linuxConsoleTools) and rFactor 2 (Needs a negative value for Steering effects strength (I used -60% or -6000 in Controller.JSON).

❯ cat src/hid-fanatecff/default.nix

{ lib
, stdenv
, fetchFromGitHub
, kernel
, kmod
, linuxConsoleTools
}:

let moduledir = "lib/modules/${kernel.version}/kernel/drivers/hid";
in
stdenv.mkDerivation rec {
  pname = "hid-fanatecff";
  version = "0.0.2";
  name = "hid-fanatecff-${version}-${kernel.version}";

  src = fetchFromGitHub {
    owner = "gotzl";
    repo = "hid-fanatecff";
    rev = "next";
    sha256 = "hHxh0VFHwLyAxUkXSpjc2VlXdyoABoenc2sAsewhLhs=";
  };

  hardeningDisable = [ "pic" "format" ];
  nativeBuildInputs = kernel.moduleBuildDependencies;

  patchPhase = ''
    mkdir -p $out/lib/udev/rules.d
    mkdir -p $out/${moduledir}
    substituteInPlace Makefile --replace "/etc/udev/rules.d" "$out/lib/udev/rules.d"
    substituteInPlace fanatec.rules --replace "/usr/bin/evdev-joystick" "${linuxConsoleTools}/bin/evdev-joystick" --replace "GROUP:=\"plugdev\"" "TAG+=\"uaccess\""
    sed -i '/depmod/d' Makefile
  '';

  makeFlags = [
    "KVERSION=${kernel.modDirVersion}"
    "KDIR=${kernel.dev}/lib/modules/${kernel.modDirVersion}/build"
    "MODULEDIR=$(out)/${moduledir}"
  ];
}

❯ cat src/configuration.nix
{ config, pkgs, ... }:

let fanatecff = pkgs.linuxPackages.callPackage ./hid-fanatecff/default.nix {};
in
{
  boot.extraModulePackages = [ fanatecff ];
  services.udev.packages = [ fanatecff ];
  boot.kernelModules = [ "hid-fanatec" ];

  environment.systemPackages = with pkgs; [
  ];
}

Full repo is here and that configuration.nix file is actually part of a bigger config here.

I will be taking a look into packaging it into nixpkgs when I get the chance.

[PhilT]

I'm going to hold off adding this to nixpkgs for now until more people here request it. Happy to do it once more :+1: are added.

I've updated my nix config to work with the latest hid-fanatecff https://github.com/PhilT/nixos-files/blob/main/src/hid-fanatecff/default.nix

I've updated my nix config to work with the latest hid-fanatecff https://github.com/PhilT/nixos-files/blob/main/src/hid-fanatecff/default.nix

I have tested it and it is working for me. I only had to use the default kernel instead of xanmod to avoid an error during kernel version check. Since I am a newcomer on NixOS I did not figure out how to deal with it yet. Thanks for the sharing.

[sigonze]

Finally I was able to make it work with xanmod. The solution is to replace ${kernel.version} by ${kernel.modDirVersion}. https://github.com/sigonze/nixos-config/blob/main/hid-fanatecff/default.nix For udev rules, games group has to be created and linuxConsoleTools has to be installed.
