💅 amdpm(4) — like, the AMD 756/766/768/8111 Power Management controller driver bestie

okay so real quick, the manual name for this one is Kernel Interfaces Manual, and today we're reading the page for AMDPM(4) — the AMD 756/766/768/8111 Power Management controller driver. yes it's a mouthful. no we're not skipping any of it. 🎀

✨ NAME ✨

amdpm — the AMD 756/766/768/8111 Power Management controller driver. that's the whole vibe. 👑

🌸 SYNOPSIS 🌸

device smbus
device smb
device amdpm

three device lines, in that order, exactly like that. that's it. that's the whole thing. slay. 💖

🦋 DESCRIPTION 🦋

so this driver hands you access to the AMD 756/766/768/8111 Power management controllers. at the moment? only the SMBus 1.0 controller function is actually implemented — like, that's the only part that's live, bestie, don't go expecting more.

the SMBus 2.0 functionality of the AMD 8111 controller? that's supported, but not here — it's over in the amdsmb(4) driver. different driver, different page, iykyk.

here's the part that's actually fun: the embedded SMBus controller of the AMD 756 chipset may give you access to the monitoring facilities of your mainboard. ✨ which means your board is basically telling you its secrets. see smb(4) for writing user code to fetch voltages, temperature and so on from the monitoring chip of your mainboard. literally the main character energy of this whole page. 🫶

🔥 SEE ALSO 🔥

all four. go read them. 💜
