Awesome, it works great to have webcam! Just, it fails in cheese, but all other programs I tried get it right:

firefox
chrome
obs
zoom-us

Thank you so much. Note that to get sound right, I needed to run alsactl init.

might be cheese has a permissions issue as mentioned here

sudo cheese

Note for 24.11:

error: Package ‘ipu6-drivers-unstable-2024-10-10’ in /nix/store/0xbni69flk8380w0apw4h640n37wn1i9-source/pkgs/os-specific/linux/ipu6-drivers/default.nix:49 is marked as broken, refusing to evaluate.

       a) To temporarily allow broken packages, you can use an environment variable
          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_BROKEN=1

          Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
                then pass `--impure` in order to allow use of environment variables.

       b) For `nixos-rebuild` you can set
         { nixpkgs.config.allowBroken = true; }
       in configuration.nix to override this.

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
         { allowBroken = true; }
       to ~/.config/nixpkgs/config.nix.

When enabled:

sudo nixos-rebuild switch

@pm-McFly, I've faced the same issue with kernel 6.6.43. :-(

p-alik · 2024-12-19T08:29:00Z

Asked for help on Discourse Upgrade to nixos 24.11 fails due to ipu6 driver

pm-McFly · 2024-12-19T08:43:01Z

I tried using the derivations found on the other gist:

see notgne2/xps_9320.nix

And tried to modified them to maybe find a revision that works, but was ultimately blocked due to inconsistent revision expectations...

AdrienLemaire · 2024-12-27T15:23:49Z

Looks like it's been fixed in NixOS/nixpkgs#368326
But I'm having a new error

$ sudo nix-channel --add https://nixos.org/channels/nixos-unstable nixos
$ sudo nixos-rebuild switch --upgrade
...

       error: xf86videointel has been removed as the package is unmaintained and the driver is no longer functional.
       Please remove "intel" from `services.xserver.videoDrivers` and switch to the "modesetting" driver.

after setting modesetting and trying again, I get

$ sudo nixos-rebuild switch --upgrade
...
       error: Package ‘ipu6-drivers-unstable-2024-11-19’ in /nix/store/bfr3xwnd4qam39i69czczlxjn1pmv340-nixos/nixos/pkgs/os-specific/linux/ipu6-drivers/default.nix:51 is marked as broken, refusing to evaluate.

Since I have literally discovered NixOS only a couple hours ago, I suppose I did something wrong 🤣

p-alik · 2024-12-27T18:12:52Z

The pull request is just back porting to 24.11. However the driver didn't work in my case. See the message on discourse

AdrienLemaire · 2025-01-12T22:27:08Z

Hi guys. Over the past 2 weeks, I have been studying nixos, improving my setup, and now revisiting this camera issue.

I am at a point where a camera is detected, but not functional.

Some thoughts:

this PR on nixos-hardware has been abandonned and could be reopened by someone capable
we could add another PR to nixos/pkgs to upgrade ivsc-firmware to the latest version and remove the let ... in from our hardwware-configuration.nix

@p-alik am I correct in thinking that nobody running nixos 24.11 or unstable has camera working at the moment ?
When digging through related github issues/PR from your discourse link, it seems like everything got resolved and merged, and that I'm probably the only one who can't manage to get his webcam working 😅

@AdrienLemaire, here the current state for my Dell XPS 13 Plus 9320

the PR ivsc-firmware: add a1_prod symbolic links to fix ipu6 webcams #295508 made let in hardware-configuration.nix obsolete. Camera works fine with Nixos 24.05

nixos-rebuild switch --upgrade fails on 24.11 and on unstable. Maybe rnhmjoj, the author of nixpkgs/commit/63f2d160a6ad12d8088e4b70140d83d720505326 can help with the matter.

       error: xf86videointel has been removed as the package is unmaintained and the driver is no longer functional.
       Please remove "intel" from `services.xserver.videoDrivers` and switch to the "modesetting" driver.

Opened an issue kernel intel_ipu6_psys bug

AdrienLemaire · 2025-01-13T15:31:25Z

thank you !

CyberT3C · 2025-07-07T21:41:07Z

@AdrienLemaire Hey what hardware do you use. I just finished my working camera setup (Dell xps 9315). I looked at the comments and your sensor, message output, looked very similiar to me. I have the same camera sensor so I bet my setup would work for you.

I uploaded my files here: https://github.com/CyberT3C/nixos-config
I commented the debug steps which gave me new information in: https://github.com/CyberT3C/nixos-config/blob/main/dell-xps-9315-cam.nix
Look at the end.

OVTI01A0 in general

v4lloopback cannot communicate with this sensor, too old
icamerascr which is included in alot ip6 packages is at the moment also not able to do
libcamerasrc works
If you want to use the device directly by /dev/videoXY make sure you have a discover logic bevor because the device will always end up with a different number in the end. Depends on boot timing.

nixos

The most important step is to patch the linux kernel if your are < 6.16. This will fix the missing GPIO Pin 0x02.
Don't use any nixos ipu6 specified camera packages. These will mess up everything. Libcamera works for OVTI01A0!
Pipewire works like a charm for me. But in the file is also a service for v4l2 fallback if you need it in any case but then pipewire won't work anymore.

Unfurtunately there is no documentation in the nixos wiki for pipewire and the camera but the correct plugin for libcamera is already included in the nixos package. All you need is to activate it.

Webbrowser support: Last but not least enable pipewire in your favorit browser and don't forget about XDG.

TLDR: Use the nixos unstable channel with Linux Kerne 6.15.4 and import my config.

{
  imports =
    [ # Include the results of the hardware scan.
      ./hardware-configuration.nix
      <nixos-hardware/dell/xps/13-9315>
      ./dell-xps-9315-mic.nix
      ./dell-xps-9315-cam.nix
    ];

  boot.kernelPackages = pkgs.linuxPackages_6_15;
