We have the firmware bits, but we also need newer Mesa. 22.3 is in staging now which should be usable with RDNA3, but I wouldn't expect a good experience until 23.x early next year.

[MasterMind2k]

Then, we wait for mesa 22.3 :).

Thanks.

You can try cherry-picking https://github.com/NixOS/nixpkgs/pull/204125 if you're OK with rebuilding the world.

[Atemu]

Alternatively, you can get https://github.com/NixOS/nixpkgs/pull/204125 's mesa an stuff its drivers output into hardware.opengl.package That works just fine for me and doesn't require any builds other than mesa.

[cidkidnix]

You'll still need to compile mesa with LLVM 15 for any RX7000 series cards, though llvmPackages_git will suffice. (or alternatively you could use #194634)

[K900]

I think it should still work with ACO?

[cidkidnix]

On llvm14, the Vulkan side it's 100% fine, on the opengl/egl side not so much, OpenGL doesn't have ACO yet, so it uses llvm for the backend, so the newer GPUs require llvm15 for OpenGL support

[LunNova]

Does Zink work instead of the old opengl stuff without llvm 15?

[K900]

Zink isn't enabled by default and is much less compliant even when it is.

[LunNova]

LLVM 15 PR: #194634

[K900]

Maybe we should try to land it before the next staging cycle then? So we can get Mesa and Rust on 15.

[athas]

Alternatively, you can get #204125 's mesa an stuff its drivers output into hardware.opengl.package That works just fine for me and doesn't require any builds other than mesa.

How do I do this without recompiling the world? By importing the staging branch tarball and picking out it's Mesa derivation, I have to compile everything, starting from perl and bison.

[K900]

Don't overlay Mesa, just set hardware.opengl.package = stagingNext.mesa.drivers

[athas]

K900 @.***> writes:

That's what I think I am doing. I have

let staging = import (builtins.fetchTarball "https://github.com/nixos/nixpkgs/tarball/staging") { config = config.nixpkgs.config; };

(I know I should pin this; just playing around now.)

Then I do

hardware.opengl.package = staging.mesa.drivers;

I don't use 'staging' for anything else. When I initiate a nixos-rebuild I am told it has to build 493 derivations, cindlug things like 'bison', 'bash', 'texinfo', 'gcc', 'llvm', 'ed', etc. This might be as expected, but I think it will take me all night to see whether it works.

[K900]

Use staging-next, not staging.

[athas]

K900 @.***> writes:

Ah, thanks! I did not realise there were two staging branches. Much more reasonable now.

[athas]

Well, it's partially working now. From what I can see the drivers in /var/run/opengl now come from mesa 22.3, Wayland still doesn't work - as expected, it complains that LLVM doesn't support the GPU. The other posts here suggests I need to use LLVM 15 to get it working. I tried this:

hardware.opengl.package = (staging.mesa.override { llvmPackages = pkgs.llvmPackages_git; }).drivers;

(Where pkgs is nixos-unstable.)

But building fails with this error:

I will try playing with it a bit more.

[K900]

LLVM 15 is being worked on in https://github.com/NixOS/nixpkgs/pull/194634

[cidkidnix]

You'll need to use https://github.com/NixOS/nixpkgs/pull/194634

Some of the patches on llvmPackages_git are completely borked

[athas]

Some progress. With

let
    staging = import (builtins.fetchTarball "https://github.com/nixos/nixpkgs/tarball/staging-next") { config = config.nixpkgs.config; };
    llvm15 = import (builtins.fetchTarball
    "https://github.com/rrbutani/nixpkgs/tarball/feature/llvm-15") {
    config = config.nixpkgs.config; };
in
  ...

and

hardware.opengl.package = (staging.mesa.override { llvmPackages = llvm15.llvmPackages_15; }).drivers;

it compiles the LLVM parts correctly. Mesa itself fails:

Dependency LLVMSPIRVLib found: NO found 14.0.0.0 but need: '>= 15.0' ; matched: '>= 8.0.1.3', '< 15.1'
Run-time dependency llvmspirvlib found: NO 

meson.build:1895:2: ERROR: Dependency lookup for LLVMSPIRVLib with
method 'pkgconfig' failed: Invalid version, need 'LLVMSPIRVLib' ['>= 15.0'] found '14.0.0.0'.

I probably need to override a few more things, but I feel that I am on the right track.

[athas]

That error is related to the OpenCL support, which I don't need for now. Oh, and now that I can use a browser instead of a terminal email client, I can provide my final notes on what worked for me, in a properly formatted way. I use this at the beginning of my config to get Nixpkgs variants from branches I need:

let
    staging = import (builtins.fetchTarball "https://github.com/nixos/nixpkgs/tarball/staging-next") { config = config.nixpkgs.config; };
    llvm15 = import (builtins.fetchTarball "https://github.com/rrbutani/nixpkgs/tarball/feature/llvm-15") { config = config.nixpkgs.config; };
in
  ...

And then I patch in Mesa like this:

  hardware.opengl.package = (staging.mesa.override { llvmPackages = llvm15.llvmPackages_15; enableOpenCL = false; }).drivers;

You'll end up compiling LLVM, clang, and mesa, which takes a little while, but it's not too bad.

All this information is already elsewhere in the thread, but summarising it in this post might help some people. Hopefully this will all be obsolete information before too long.

[Atemu]

@athas perhaps you could also try using Zink via Vulkan without LLVM_15; would love to know whether that's an option that works for RX 7000.

[athas]

How would I do that? I don't have that much experience with tweaking Mesa.

Also, it should be noted that despite the above functionally working (even for GPGPU, to my great surprise), it's a little unstable for games, with a crash maybe every hour. That is par for the course for new AMD GPUs and will probably resolve itself when the components become more well supported.

[Atemu]

@athas put "zink" in our mesa's galliumDrivers and set MESA_LOADER_DRIVER_OVERRIDE=zink globally.

[mustafasegf]

I'm sorry if it's the wrong place to ask. but i have 7900 xtx and able to compile mesa from next staging. But my cursor suddenly gone from x11 server. Do i need to specify some xorg config? thanks

[K900]

You don't need to do that, Mesa 22.3 is in the current unstable now. Make sure you're not using the amdgpu driver and using the modesetting one.

[jansol]

Hm, I'm not even getting sddm to show up with nixos-unstable and the llvm15 override shown here. With amdgpu in services.xserver.videoDrivers I get a frozen black screen with a non-blinking console cursor in the top left corner. With modesetting I don't even get that. Also switching to a different vt does not seem to work...

If I set services.xserver.enabled = false I get a usable console and mpv with --vo=gpu-next --gpu-context=drm does work fine, though.

[jansol]

FWIW dmesg logs a couple of errors during boot and when trying to start Xorg.

Also the console is weirdly janky, like it completely stops rendering for a bit every few seconds.

[athas]

I don't know about Xorg (I use Wayland), but the console jankyness was fixed by adding this kernel boot parameter: amdgpu.ppfeaturemask=0xfffd3fff.

[LunNova]

Could try using the modesetting driver with xorg.

[Atemu]

@jansol kernel bugs should be reported to https://gitlab.freedesktop.org/drm/amd/-/issues/.

[edel-km]

@athas omg thank you for your effort you put into your dotfiles .. i've managed to run my 7900 xt now @rrbutani thank your for working on llvm15 ... this made running my new 7900xt possible !!

[SeineEloquenz]

I tried using what @athas wrote above, but I get a 404 on downloading the llvm15 tarball. Is this still the recommended way to get hardware acceleration working or can someone please help me out what to do?

[Atemu]

@SeineEloquenz that's due to @rrbutani having deleted their branch because #194634 was merged. It should be in nixos-unstable soon-ish https://nixpk.gs/pr-tracker.html?pr=194634

[SeineEloquenz]

Thank you very much for the quick reply! For anyone reading this till the newer nixos-unstable drops I got it working now via:

let
  staging = import (builtins.fetchTarball "https://github.com/nixos/nixpkgs/tarball/staging-next") { config = config.nixpkgs.config; };
in

hardware.opengl.package = (pkgs.mesa.override { llvmPackages = staging.llvmPackages_15; enableOpenCL = false; }).drivers;

[Atemu]

Also, with https://github.com/NixOS/nixpkgs/pull/213158, you should have 7000-series support in mesa by default.

You could try building your system with staging-next which already has the PR inside it: https://github.com/NixOS/nixpkgs/pull/211923 https://nixpk.gs/pr-tracker.html?pr=213158
(staging-next will become the next master/unstable, it's not as scary as it sounds.)

[rrbutani]

(sorry! totally forgot people were using the branch directly, I've restored it and I'll leave it up until the PR hits nixos-unstable)

[PedroHLC]

In case someone (with flakes) wants bleeding-edge mesa (from git), with llvm15+mesa from staging-next, and with a fallback entry:

1) add these flakes inputs:

staging-next.url = "github:NixOS/nixpkgs/staging-next";
mesa-git-src = {
  url = "github:chaotic-aur/mesa-mirror/main";
  flake = false;
};

2) forward them through specialArgs; 3) add this module to your output:

{ pkgs, lib, mesa-git-src, staging-next, ... }:
let
  future = staging-next.legacyPackages.${pkgs.system};

  mesaGitApplier = base: base.mesa.overrideAttrs (fa: {
    version = "23.0.99";
    src = mesa-git-src;
    buildInputs = fa.buildInputs ++ [ base.zstd base.libunwind base.lm_sensors ];
    mesonFlags = lib.lists.remove "-Dgallium-rusticl=true" fa.mesonFlags; # fails to find "valgrind.h" with 23.0+ codebase
  });

  mesa-bleeding = mesaGitApplier future;
  lib32-mesa-bleeding = mesaGitApplier future.pkgsi686Linux;
in {
  # Apply latest mesa in the system
  hardware.opengl.package = mesa-bleeding.drivers;
  hardware.opengl.package32 = lib32-mesa-bleeding.drivers;
  hardware.opengl.extraPackages = [ mesa-bleeding.opencl ];

  # Creates a second boot entry without latest drivers
  specialisation.stable-mesa.configuration = {
    system.nixos.tags = [ "stable-mesa" ];
    hardware.opengl.package = lib.mkForce pkgs.mesa.drivers;
    hardware.opengl.package32 = lib.mkForce pkgs.pkgsi686Linux.mesa.drivers;
  };
}

[jansol]

It may also be a good idea to bump your kernel to linuxPackages_testing. I could not get to the desktop at all with 6.1.x, had to update to 6.2-rc5. With that and bleeding edge mesa it has finally been somewhat usable.

Thanks for this, implemented in my config and is working.

seems like GDM isnt working with kernel 6.1.8 and mesa 23 ... anyways i am using hyprland, and if i start it with greetd it is working fine.

how did you change to kernel 6.2-rc5 ?

i've done

  boot.kernelPackages = pkgs.linuxPackagesFor (pkgs.linux_testing.override {
    argsOverride = rec {
      src = pkgs.fetchurl {
        url = "https://git.kernel.org/torvalds/t/linux-6.2-rc6.tar.gz";
        hash = "sha256-rEpJYw5O6OHSwNY8LxlCsw0p9+u9BUjTQ8FsB6+fLbc=";
      };
      version = "6.2-rc6";
      modDirVersion = "6.2-rc6";
    };
  });

but it isnt building for me ... getting

only thing i have found so far, that it could be an issue with AMD processors !?

[jansol]

@edel-km oh right, I also went through pkgs/os-specific/linux/kernel/common-config.nix and simply commented out the options listed in the error message. (I was building from a local nixpkgs checkout anyway, not sure how to do it with an override)

[edel-km]

@jansol thanks for pointing me the right direction

  boot.kernelPackages = pkgs.linuxPackagesFor (pkgs.linux_testing.override {
    argsOverride = rec {
      src = pkgs.fetchurl {
        url = "https://git.kernel.org/torvalds/t/linux-6.2-rc6.tar.gz";

      version = "6.2-rc6";
      modDirVersion = "6.2.0-rc6";
    };
    ignoreConfigErrors = true;
  });

this is the way ...

[Slabity]

Out of curiosity, has anyone here been able to get the USB-C port on these cards to work on NixOS? If so, are there any other changes required to get it to function properly?

[cidkidnix]

amdgpu seems to drop the card into a weird state on shutdown sometimes @Slabity, I've got it to work (when it stops working) by turning off my computer, flipping the power supply off (or removing the cord) and pressing the power button a few times to drain the motherboard caps of power, then turning everything back on

[Slabity]

@cidkidnix - Wow. I could not find anything about this issue in upstream discussions or anywhere else. Glad to know I'm not the only one with this is affecting. Flipping the PSU after shutdown seems to have fixed it, so you saved me quite a bit of time trying to debug what the problem was.

As far as other PSU-related issues are concerned, I also found out that you should not be using the normal daisy-chained PCIe cables for high-wattage graphics cards. Use separate cables going to separate PSU rails for each 8-pin PCIe connector on your card :upside_down_face:

I tried to add libclc to the system packages without any success.

Also I found out that llvmPackages_15 hit unstable, so no need to put staging anymore:

  hardware.opengl.package = (pkgs.mesa.override {
    llvmPackages = pkgs.llvmPackages_15;
    enableOpenCL = false;
  }).drivers;

This is no longer necessary. Just use the latest nixos-unstable.

What do I put in hardware.opengl.package then? Something like pkgs.mesa_latest?

[K900]

Nothing. The default is fine.

Can I remove the featuremask?
