gpuboard_temp(9)

💖 gpuboard_temp(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's a lil file called gpuboard_temp, and it's lowkey iconic for one very specific reason. let's get into it 🫶

✨ NAME ✨

gpuboard_temp — the file that tells you how warm your GPU board is rn 🌡️

🌸 DESCRIPTION 🌸

okay so here's the tea: the amdgpu driver ships a sysfs API that lets you pull the current gpuboard temperature metrics data. and the file that does it? yeah, it's literally called gpuboard_temp. main character file energy fr fr 👑

how do you use it? bestie, you just read it. that's it. reading the file will dump all the current gpuboard temperature metrics data — the whole thing, no cap, at once. it's giving "one file, all the temp tea" 💅✨

💀 quick vibe check: it says read. it does not say write, poke, prod, or "what if I just…". reading = immaculate. that's the whole assignment.

like, so many siblings. this file is part of a whole friend group, and you should absolutely go meet them all 🌈
