mesa-asahi: Desktop environment fails to load due to outdated vendor configuration.

[foldfree]

Using Cosmic DE on a macbook air m2. Any graphics fails to load completely after updating from this commit.

I went asking for help to the cosmic flake maintainer and got this feedback:

vendor/default.nix looks rather out of date with nixpkgs mesa derivation and should be updated there.

She pointed out this commit as a reference: NixOS/nixpkgs@09cbcd6#diff-630909e9824dc40d9fef6c4c8b149321677e270d5be823fafd370baac098e408R306

Same issue, just with KDE Plasma. SDDM fails to show, but I get a "[ OK ] Reached target Graphical Interface", but it never shows.

I have no idea how to bug fix this, dmesg shows nothing, sddm log show nothing, where do I begin?

[tpwrules]

There was just a major change in how Mesa works in upstream unstable nixpkgs. I've had some discussion with them and will implement fixes in a bit.

[givtrah]

Awesome. I've had smooth sailing with your Asahi implementation on Nix so far, thanks for the good work!

[Isolaryn]

@tpwrules Is there a link to this upstream conversation/issue?

[marcusramberg]

Very hacky and not fit for a PR, but I managed to get mesa-asahi-edge built against the current version from nixpkgs-unstable here which works https://github.com/marcusramberg/nixos-apple-silicon/tree/mesa in case someone needs a temp fix until a proper one is released.

[marcusramberg]

Btw didn't 24.3 add support for the asahi driver? (https://www.altusintel.com/public-yycr5j/) so if NixOS/nixpkgs#371771 got merged it might be easier to override the upstream directly (nix-build --expr '((import ./. {}).pkgs.mesa.override { galliumDrivers = [ "llvmpipe" "radeonsi" "svga" "asahi" ]; vulkanDrivers = [ "asahi" "swrast" ]; }).drivers') on that PR builds on asahi for me and seems to include the ashi drivers in the result.

I am getting this error when I use @marcusramberg fix. Is this related?

@darbster145 this seems to be a failure to apply a patch to systemd? I don't see how that could be related to my fix, which only afffects mesa.

[oliverbestmann]

I've removed the vendored package from my fork for the time being. Works direkctly with latest nixpkgs-unstable.

Thank you @oliverbestmann I was able to get yours working

Ya, I am not sure, I dont have anything in my config patching systemd. I was able to get @oliverbestmann fix working though.
