[ahoneybun]

Description of changes

Adds the system76 galp5 (1650 version in this case)

Things done

• Tested the changes in your own NixOS Configuration
• Tested the changes end-to-end by using your fork of nixos-hardware and
  importing it via <nixos-hardware> or Flake input

The NVIDIA driver is loaded with this configuration:

Though system76-power graphics does not seem to work:

[aaronh@garrus:~]$ system76-power graphics
daemon returned an error message: "The name com.system76.PowerDaemon was not provided by any .service files"

I have the hardware.system76.enableAll enabled in my configuration:

https://gitlab.com/ahoneybun/nix-configs/-/blob/main/hosts/x86_64/garrus/configuration.nix?ref_type=heads

I'll add add the system76 generic part as well of nixos-hardware to test.

[ahoneybun]

Yep I needed that for the system76-power service!

[aaronh@garrus:~]$ system76-power graphics
nvidia

though I don't think this works on NixOS anyway:

[aaronh@garrus:~]$ system76-power graphics integrated
setting graphics to integrated
daemon returned an error message: "failed to execute update-initramfs command: No such file or directory (os error 2)"

[ahoneybun]

I think this might be that NixOS has version 1.1.23 of system76-power. I don't think this not working would be a blocking to add this system since the gaze18 was not blocked though.

[Mic92]

I am bit unsure if this is actually hardware configuration and not just about playing old games, which not everyone does:

Suggested change

enable32Bit = lib.mkDefault true;

[ahoneybun]

I'm pretty sure Steam will need it in general as it needs 32bit even if you have modern games.

[Mic92]

Ok, but than if we enable the module everywhere, should we not just do it in one place? i.e. nvidia.nix?

[Mic92]

Is this not enabled by the nividia module?

[ahoneybun]

@Mic92 I just copied the config from the gaze18 so if we need to address things here I can make a PR for that model as well.

Likely yes.

[ahoneybun]

If I remove those options then rebuild and reboot nvidia-smi does not work so I think it is needed.

[ahoneybun]

Alright @Mic92 I was incorrect and with the current changes nvidia-smi shows that the NVIDIA driver is loaded though system76-power graphics now reports this:

[aaronh@garrus:~]$ system76-power graphics
compute

so I think it is needed for NVIDIA mode at least but with Compute it should be similar to Hybrid.

[ahoneybun]

Alright so I think compute is because I'm in the 6.6 kernel now and before I was in the 6.10 kernel series. I can't build 6.11 with the system76-module which is why I'm back in 6.6.

[ahoneybun]

Alright with the current state of this PR puts the system in PRIME Offload Mode which I think is a good middle ground. You can use the NVIDIA GPU when needed and is pretty close to system76-power's Hybrid mode.
