The firmware location appears incorrect.

[ITY]

When I use my flakes configurations, and add apple-silicon-support to configuration, it reports that Asahi perpheral firmware extraction is enabled but the firmware location appears incorrect.

I ran into this whilst attempting to build my NixOS+Asahi Configuration while on a MacOS, so I dug into this. You can see the relevant bits here:

nixos-apple-silicon/apple-silicon-support/modules/peripheral-firmware/default.nix

Lines 4 to 11 in bdc68b4

     assertions = lib.mkIf config.hardware.asahi.extractPeripheralFirmware [ 
       { assertion = config.hardware.asahi.peripheralFirmwareDirectory != null; 
         message = '' 
           Asahi peripheral firmware extraction is enabled but the firmware 
           location appears incorrect. 
         ''; 
       } 
     ]; 

nixos-apple-silicon/apple-silicon-support/modules/peripheral-firmware/default.nix

Lines 48 to 54 in bdc68b4

 default = lib.findFirst (path: builtins.pathExists (path + "/all_firmware.tar.gz")) null 
   [ 
     # path when the system is operating normally 
     /boot/asahi 
     # path when the system is mounted in the installer 
     /mnt/boot/asahi 
   ]; 

In essence, you have to have the peripheral firmware installed at the default locations of either /boot/asahi or /mnt/boot/asahi. If you have it at a different location, you should specify a different peripheralFirmwareDirectory or you could disable firmware extraction with extractPeripheralFirmware = false;. These directories should exist when installing Asahi Linux via this repo (or after).

In my case, it won't work because I'm building my NixOS configuration on a NixOS VM (the Nix-Darwin Linux builder) that doesn't have the /boot/asahi or /mnt/boot/asahi directory (this is fine for me as I was just testing my build).

Hope this information is helpful as I also wanted to understand why my test build was failing.

I'm having issues with this.
I was able to rebuild by setting extractPeripheralFirmware = false;
But, now I can't use internet, seems like other things are broken?

But I can't build if I turn it on..
and its definitely located at /boot/asahi/all_firmware.tar.gz...

Edit:
I can rebuild if I pass --impure to the command..

Edit2:
But I donnwaanna have to pass --impure.. I like pure

You need to copy the firmware into your NixOS configuration repository as the README reads:

mkdir -p /mnt/etc/nixos/firmware && cp /mnt/boot/asahi/{all_firmware.tar.gz,kernelcache*} /mnt/etc/nixos/firmware

And then reference it in your NixOS configuration (and make sure firmware sub-directory is check-ed in to your NixOS configuration repository):

{
  # Specify path to peripheral firmware files.
  hardware.asahi.peripheralFirmwareDirectory = ./firmware;
}

I added that line, got a new error (yay, progress) but what’s going on with this? What’s preventing a rebuild here? https://paste.ee/p/XqAK2

Did you commit the firmware subdirectory to your repository ?

Think so?

[Ashish]

Sorry, at a glance, this seems like a problem with your flake inputs, and esp. processing flake-parts flake in here. Nothing to do with firmware as I mis-assumed.

How do I fix it?
All my other systems use that.. I'm not really sure what it is.
