viapm — VIA chipsets Power Management controller driver. (This is VIAPM(4) from the Kernel Interfaces Manual, bestie — folded in right here so you know what page you’re on. 💅)

✨ SYNOPSIS ✨

🌸 DESCRIPTION 🌸

Okay so this driver gives you access to the VIA chipset Power Management Unit family. The whole squad is VT82C586B, VT82C596A, VT82C596B, VT82C686A and VT8233. ✨

The embedded controller of the VIA chipset may give you access to the monitoring facilities of your mainboard. Your mainboard is lowkey trying to tell you things, and this is how you listen. 🫶

The 586B support is made by software, whereas the other controllers support the SMBus protocol by hardware. See smb(4) for writing user code to fetch voltages, temperature and so on from the monitoring chip of your mainboard. That’s the whole vibe. 💖
