💖 VIAPM(4) 💖

okay bestie, so this is the manual page for viapm — the VIA chipsets Power Management controller driver, straight out of the Kernel Interfaces Manual. yes the title says VIAPM(4) twice, that's just how manpages are, they're extra like that 💅

✨ NAME ✨

viapm — VIA chipsets Power Management controller driver

🎀 SYNOPSIS 🎀

device viapm

🦋 DESCRIPTION 🦋

So this driver is your all-access pass to the VIA chipset Power Management Unit family. The members of the squad are: VT82C586B, VT82C596A, VT82C596B, VT82C686A and VT8233. no cap, that's the whole group chat 📋

The embedded controller of the VIA chipset may give you access to the monitoring facilities of your mainboard. (yes, may — it's giving "we'll see" energy, don't come for me 🙈)

Now here's the tea 🍵 the 586B support is made by software, whereas the other controllers support the SMBus protocol by hardware. different vibes, same destination ✨

Wanna write your own user code to fetch voltages, temperature and so on from the monitoring chip of your mainboard? Go read smb(4). That's the one that tells you how. literally the blueprint 🫶

the whole friend group, go say hi to all of them 💜
