update nixos ucm install #141

dj1ch · 2024-02-20T06:38:52Z

pretty much the title, just updated the commit hash, and some info on nixos config locations. install script wise nothing seemed to be out of the ordinary, copied the ucm to /usr/share/alsa like normal. didn't want the nixos page to become outdated @WeirdTreeThing

src/docs/installing/distros.md

ChocolateLoverRaj · 2024-03-29T04:22:18Z

@dj1ch did you test the nixos instructions on a Chromebook? If you did, can you provide the full nix config? I'm trying the nixos guide and it's compiling stuff for over 10 minutes and taking up a lot of storage space. I think the nixos guide needs some fixing in addition to just updating the commit used.

src/docs/installing/distros.md

ChocolateLoverRaj · 2024-03-30T19:52:25Z

@dj1ch what about the issue of "50GB of rebuilds"?

@dj1ch what about the issue of "50GB of rebuilds"?

ok, pretty much did the same thing you did with audio.nix, tested it on my machine and it runs fine. nix garbage collection also freed up some of my storage which was nice.

ChocolateLoverRaj · 2024-03-30T21:26:51Z

A few issues:

The ucm-conf is a few months old (Should work for most devices, but ideally it should use the latest ucm-conf which will also work for all generations. I'm planning on changing the audio config to use the latest version, but let me know if you want to do it and then I won't, and I'll just test it out once you do.
There appear to be instructions for AVS but does AVS work? Do some files need to be added for AVS?
What about max98357a (the danger)?
AMD audio not implemented yet (this is ok but maybe it should be mentioned in the docs)
Not needed, but 51-increase-headroom.lua should also be added
And you can use fetch from GitHub instead of fetching a zip

ChocolateLoverRaj · 2024-03-30T21:35:53Z

THis is my config btw: https://github.com/ChocolateLoverRaj/nixos-system-config/blob/84c9e4034a2fb85b08ac4b3a7487ba163efd860b/audio.nix

we can probably try using the latest commit if possible. ill test it and ill let you know.

WeirdTreeThing · 2024-03-30T23:48:54Z

bruh why are you still using that repo

ChocolateLoverRaj · 2024-04-01T04:29:19Z

bruh why are you still using that repo

Should we use https://github.com/WeirdTreeThing/alsa-ucm-conf-cros/tree/standalone ? Is that "your upstream" repo for Chromebook audio, and not chromebook-ucm-conf?

probably this issue sums it up

ChocolateLoverRaj · 2024-04-01T05:21:21Z

Except that we could just use the latest commit of chromebook-ucm-conf and it will work for all SOF generations. So I'm still confused.

dj1ch · 2024-04-01T06:18:43Z

@ChocolateLoverRaj this is my current audio.nix, if you want to test with the last alsa-ucm-conf-cros release. im assuming this is how wtt wanted this to be packaged.

{ config, pkgs, lib, ... }:


let
  cb-ucm-conf = pkgs.alsa-ucm-conf.overrideAttrs {
    wttsrc = pkgs.fetchurl {
      url = "https://github.com/WeirdTreeThing/alsa-ucm-conf-cros/archive/refs/tags/0.4.tar.gz";
      hash = "sha256-3D+wUj8O2y+OEcdvoXzmU1IxSoc44qoV5+I5AO1tl2o=";
    };
    unpackPhase = ''
      runHook preUnpack
        tar xf "$wttsrc"
      runHook postUnpack
    '';
    installPhase = ''
      runHook preInstall
      mkdir -p $out/share/alsa
      cp -r alsa-ucm*/ucm2 $out/share/alsa
      runHook postInstall
    '';
  };
in
{
  # audio modprobes go here
  boot = {
    extraModprobeConfig = ''
      options snd-intel-dspcfg dsp_driver=3
    '';
  };  

  environment = {
    systemPackages = with pkgs; [
      maliit-keyboard # optional
      sof-firmware
    ];
    sessionVariables.ALSA_CONFIG_UCM2 = "${cb-ucm-conf}/share/alsa/ucm2";
  };

  system = {
    replaceRuntimeDependencies = [
      ({
        original = pkgs.alsa-ucm-conf;
        replacement = cb-ucm-conf;
      })
    ];
  };
}

ChocolateLoverRaj · 2024-04-01T06:24:29Z

@dj1ch can u plz replace fetchurl with fetch from github?

ChocolateLoverRaj · 2024-04-01T06:31:44Z

I mean https://ryantm.github.io/nixpkgs/builders/fetchers/#fetchfromgithub

ChocolateLoverRaj · 2024-04-01T14:37:07Z

Also include 51-increase-headroom.lua. That's what I did in my config. There are different instructions for 23.11 and unstable.

ninelore · 2024-04-16T16:05:36Z

Also keyd device ids
https://github.com/WeirdTreeThing/cros-keyboard-map/blob/main/cros-keyboard-map.py#L6-L20

ChocolateLoverRaj · 2024-04-16T18:11:04Z

I'll test this once it's completely ready

ChocolateLoverRaj · 2024-04-16T22:10:58Z

what about the avs dmic config?

@WeirdTreeThing I think NixOS audio setup is SOF only atm. Idk if there are even any NixOS users who use AVS Chromebooks.

there are definitely avs users, iirc at least one having audio issues. @WeirdTreeThing may be referring to this repo, although I could be wrong on that one. for that we may just need to clone and use make to build it.

Not what I was talking about. I meant this

ChocolateLoverRaj · 2024-04-17T00:12:48Z

@WeirdTreeThing is including that one file enough to get AVS to work on Chromebooks on NixOS?

ChocolateLoverRaj · 2024-04-17T00:13:28Z

They'll have to test it out then. Are they on GitHub?

i could try and ask them about it, it was on the chrultrabook discord server.

No, all it does is make the mic work.

Overall weird and possibly broken nix syntax.

ChocolateLoverRaj · 2024-04-18T21:13:44Z

Once the replace dependency thing works with Nix flakes I think it would be nice to have a separate repo with Chromebook config and then NixOS Chromebook users can just add that repo.

It should be possible

ninelore · 2024-04-18T21:41:03Z

Example config (SOF, cros-standard kb, 24.05)
https://github.com/ninelore/dots.nix/blob/master/nixos/cros-sof-std.nix

ninelore

L177 onwards is still a confusing mess.

Merge modprobe part and codeblocks with the wireplumber so we have 1 codeblock for each SOF/AVS1/AVS2 and 23.11/24.05
Use Collapsing sections for those

Example

Foobar

function logSomething(something) {
  console.log('Something', something);
}

<details>
<summary>Example</summary>

Foobar

function logSomething(something) {
  console.log('Something', something);
}

</details>

@dj1ch it would be nice if you made your own repo with nix files and instructions for Chromebook audio
