EmbeddedController VS nixos-hardware

git clone --depth 1 https://github.com/FrameworkComputer/EmbeddedController cd EmbeddedController make utils sudo ./build/bds/util/ectool #USE AT YOUR OWN RISK - YOU CAN BRICK YOUR LAPTOP

When I was getting ready to flash again, I noticed an issue about the compiler version used to build the firmware binary. I followed the advice, but more importantly I noticed that the issue has been recently fixed, and in the resolution, the maintainer says "Next release (hx20 3.19, hx30 3.07) will include them". It reminded me of something crucial: the Framework EC firmware source code repo doesn't have any particular indication of its level of stability at any given commit. Which commits could be considered fully tested releases? What if the head of the branch introduces a bug that they're working on fixing?

The EC code on the normal Framework devices is already based on the Chrome EC code anyway. https://github.com/FrameworkComputer/EmbeddedController

EC firmware is open sourced by framework: https://github.com/FrameworkComputer/EmbeddedController

There the keyboard input is handled by the embedded controller: https://github.com/FrameworkComputer/EmbeddedController/blob...

On the 16 the keyboard is a USB keyboard that could even be used standalone, without the laptop.

I tried the pre-compiled `ectool` from the TamtamHero's repository as we and comiled the EmeddedController from Framework (from this repository). Both give the same error message.

Great reminder that (as of right now) we're far removed from hardware that is 100% free (as in freedom). The closest we've got is probably provided by Raptor Computing Systems. However not everyone in the world is privileged enough to own such devices unfortunately. And I haven't dabbled into other possible mishaps that come with using such devices. The lack of "free-hardware" is a major concern though. I'd argue that there aren't enough reasons to be optimistic about this as of right now. Therefore our best bet is to not let good be the enemy of perfect; light at the end of the tunnel...

As far as I'm aware the only way to manually change the fan speed is using `ectool` from https://github.com/FrameworkComputer/EmbeddedController/

We open sourced our Embedded Controller (EC) firmware and made it available on GitHub for you to modify if you wish.

Always useful to look at the seemingly endless stream of Linux information, the Arch wiki:

Also NixOS has a nixos-hardware repository with configurations for some laptops:

https://github.com/NixOS/nixos-hardware/tree/master/asus/zep...

Reasonably legible if you ever programmed anything

{ imports = [ # Include the results of the hardware scan. ./hardware-configuration.nix # Additional hardware specific configuration # https://github.com/NixOS/nixos-hardware ];

You could try this repo for hardware support on various laptops if yours is on it: https://github.com/NixOS/nixos-hardware

https://github.com/NixOS/nixos-hardware

Btw, for starters, I think you can learn a lot by checking other's configurations and from things like https://github.com/NixOS/nixos-hardware. There are a lot of useful/essential configurations that are not enabled by default.

in that case do note that this module assumes you use nixos-hardware, otherwise you can remove lines 161-165. I can also send you my VM's libvirtd .xml file when you get around to creating it.

My computer is a Lenovo Legion 5 Pro with a dual GPU setup (AMD iGPU + Nvidia DGPU) where I'm using a "hybrid mode" configuration provided by nixos-hardware, using PRIME offload.

Not too long ago nixos-hardware changed the default Xorg driver for AMD to modesetting from amdgpu.
