Graphics acceleration not loading with NixOS 24.05

[autrimpo]

After updating to 2024-09-03 I'm getting issues loading the mesa driver:

[jmastr]

can confirm. same here

[matteocavestri]

I am experiencing the same issue. I also noticed that home-manager outputs the following warning: libEGL warning: egl: failed to create dri2 screen.

During the update, there was the following diff of packages (perhaps one of the removed packages is causing the problem):

Version changes:

[rowanG077]

I cannot reproduce this with a NixOS unstable + M2 Max + non-homemanger hyprland. Could someone post their kernel log?

[jmastr]

I use NixOS stable on an M1. Here is the kernel.log

[matteocavestri]

I believe the issue lies in the following error: apple-dcp 38bc00000.dcp: RTKit: syslog message: PPipeDCP_H13P.cpp:11109: IOMFB updateFrequencies EDT ERROR: getClockFrequency(0) (237333328) < videoClock 402278400! Giving up on frequencies. This error points to a mismatch between getClockFrequency() and videoClock, indicating that the system is unable to properly synchronize the display frequency. The system is attempting to set a clock frequency of 237.333328 MHz, while the expected video clock is 402.278400 MHz.
I will also review my kernel log to check for any additional details.

[matteocavestri]

My kernel log is different, but I am still encountering errors related to getClockFrequency(). Specifically, I find this error: PPipeDCP_H13P.cpp:11092: IOMFB updateFrequencies: minimum-frequency property not found, using getClockFrequency(0) instead. It seems to be connected to the kernel log of @jmastr.
kernel.log

[autrimpo]

Here's mine, I also see the frequency error. kernel.log

[matteocavestri]

The issue does not seem to be related to getClockFrequency() as I initially thought, because it occurs in both kernels. However, when comparing the kernel logs between versions 6.9.12 and 6.10.6, the following differences emerge:

1. Missing initialization of the Asahi GPU in kernel 6.10.6:

   • In kernel 6.9.12, the Asahi GPU is detected and initialized correctly, with messages confirming the activation of the MMU and device tree configurations. An excerpt from the kernel log showing the GPU initialization in version 6.9.12:

     [    2.336925] asahi 206400000.gpu: MMU: initialized
     [    2.336927] asahi 206400000.gpu: GPU ID registers: 0x4021100 0x40a04 0x30808 0x40404 0x1320300 0x101311
     [    2.336931] asahi 206400000.gpu: GPU Information:
     [    2.336932] asahi 206400000.gpu:   Type: G13G
     [    2.336933] asahi 206400000.gpu:   Clusters: 1
     [    2.336934] asahi 206400000.gpu:   Cores: 8 (8)
     [    2.336934] asahi 206400000.gpu:   Frags: 8 (8)
     [    2.336935] asahi 206400000.gpu:   GPs: 4 (4)
     [    2.336936] asahi 206400000.gpu: Getting configuration from device tree...
     [    2.337151] asahi 206400000.gpu: Dynamic configuration fetched
     

   • In kernel 6.10.6, there are no messages related to the Asahi GPU, indicating that the driver is not being loaded or that the GPU is not being recognized.

2. Initialization of the simpledrm framebuffer:

   • The simpledrm framebuffer is initialized correctly in both kernel versions. However, in kernel 6.10.6, it seems to be the only display-related component that is loaded, with no further initialization of the GPU.

kernel-6.9.12.log

[jmastr]

This is my kernel.log when switching to nixos-unstable. after that GPU is working fine, which means it is "just" a missing dependency on stable?

[matteocavestri]

Does anyone have an idea about how to fix this dependency issue on stable 24.05?

[dxwil]

Same thing happens to me, Hyprland doesn't launch

[nick-disiere]

Do we know what packages are causing the issue? I can try various overlays in my flake if not.

[mogery]

Setting

hardware.asahi = {
    useExperimentalGPUDriver = true;
};

fixed this for me. (I'm also using unstable.)

[jmastr]

@mogery can't confirm. i have useExperimentalGPUDriver = true; set as well and on nixos-24.05 GPU driver does not load

[dxwil]

@mogery I have that set aswell, still does not load

[mogery]

@mogery I have that set aswell, still does not load

Are you on unstable nixpkgs or 24.05? Is that + unstable a universal workaround for now?

[dxwil]

@mogery I have that set aswell, still does not load

Are you on unstable nixpkgs or 24.05? Is that + unstable a universal workaround for now?

I'm on 24.05 with a few unstable packages

[jmastr]

@mogery my workaround is to switch my nixos and home-manager channels to nixos-unstable resp. master, i.e.:

$ sudo nix-channel --list
apple-silicon-support https://github.com/tpwrules/nixos-apple-silicon/archive/main.tar.gz
home-manager https://github.com/nix-community/home-manager/archive/master.tar.gz
nixos https://nixos.org/channels/nixos-unstable
nixos-unstable https://nixos.org/channels/nixos-unstable

Note:

$ uname -a
Linux apple-macbook-pro 6.10.6-asahi #1-NixOS SMP PREEMPT_DYNAMIC Tue Jan  1 00:00:00 UTC 1980 aarch64 GNU/Linux

I wait until 24.11 gets released and then I will switch back to stable channels.

[lukaslihotzki]

The issue probably is that NixOS 24.05 ships Rust 1.77, but kernel 6.10 requires Rust 1.78 for CONFIG_RUST. Therefore, CONFIG_RUST is disabled when building the current kernel on 24.05. This can be verified with zcat /proc/config.gz | grep CONFIG_RUST (empty with 24.05, set to yes with unstable).

[mogery]

Wow, finding that must've been hell. Thank you!

[autrimpo]

@lukaslihotzki You're spot on, thank you! I made a local overlay for the kernel:

(final: prev: let
  nixpkgs-asahi = import inputs.apple-silicon.inputs.nixpkgs {};
in {
  linux-asahi = nixpkgs-asahi.callPackage "${inputs.apple-silicon}/apple-silicon-support/packages/linux-asahi" { };
})

and things work fine now.

[dvaerum]

I am using nixos-unstable and when I try to use

hardware.asahi.useExperimentalGPUDriver = true;

I get the following error, have anyone else encountered this? or have any good ways of fixing it/tracking it down?

Update:

I figured it out, it is because I am using flakes. To make it comparable with flakes, one also needs to add experimentalGPUInstallMode = "overlay"; which does require a re-compile of multiple packages and some of the are quite time-consuming to build.

  hardware.asahi = {
    useExperimentalGPUDriver = true;
    experimentalGPUInstallMode = "overlay";
  };

@dvaerum I have useExperimentalGPUDriver as true and experimentalGPUInstallMode unset and it doesn't error when I build. If you want you can post/link your config somewhere and I'll build/diff it with mine. Might save you some compile time.

The issue probably is that NixOS 24.05 ships Rust 1.77, but kernel 6.10 requires Rust 1.78 for CONFIG_RUST. Therefore, CONFIG_RUST is disabled when building the current kernel on 24.05.

What if there were two linux-asahi kernel packages? One that would track the latest Asahi patches and one that would track a more stable kernel with a non-latest Asahi patchset but compatible with stable NixOS channels?

(This would tie in nicely with #182 (comment), that comment having a bit more details)

Are you using flakes? Because I am using flakes and the documentation said that replace (the default) does not work with flakes.

[xeniagda]

For flakes, one has to run nixos-rebuild with the --impure option to let the replace-option work properly.

[dvaerum]

Interesting @xeniagda, do you know if I can declare that inside flake as some variable? Something like

{
  flake-settings.impure = true;
  inputs = { ... };
  outputs = { ... };
}

This is likely due to NixOS stable having a too-old version of Rust.

As mentioned, stable support is on a best-effort basis. 24.11 is almost here so I do not plan to address this. If you need graphics acceleration before then, please downgrade the Apple Silicon support module.
