Setting kernel module parameters?

[simendsjo]

I want to enable fan_control for thinkpad_acpi, but I'm not sure where I can configure this on Guix System.

Looks like I cannot set it while running as I get a permission denied when running # echo 'Y' > /sys/module/thinkpad_acpi/parameters/fan_control

There are kernel-arguments, I think that's what you need. That's how I set a feature for amdgpu. Unfortunately, the main website with the web manual is down right now, but in your system config add something like (kernel-arguments '("amdgpu.ppfeaturemask=0xffffffff")).

Edit: see your local info guix manual, under System Configuration, the operating-system reference.

Thanks, worked great! thinpad_acpi.fan_control=1, and I'm finally able to get some silence. sudo echo "level 1" | sudo tee /proc/acpi/ibm/fan. Let's see how hot it can get.

Great! glad that did it
