SXITEMP(4)

💖 SXITEMP(4) 💖

okay so bestie, welcome to the Kernel Interfaces Manual — section 4, we're in kernel-land, it's giving very much "the hardware speaks and we listen" ✨

---

🌡️ NAME 🌡️

sxitemp — the Allwinner temperature monitor, aka your SoC's own little vibe check on how hot it's running 🔥

---

🎀 SYNOPSIS 🎀

sxitemp* at fdt?

that's it. that's the whole configuration. star means wildcard, at fdt? means it attaches to the flattened device tree, no cap 🦋

---

✨ DESCRIPTION ✨

so the sxitemp driver is literally the support system for the temperature sensors that live inside the Allwinner A64, H3, H5 and R40/V40 SoCs 💅 it's out here reading the internal thermals so you don't have to guess.

and how do you, like, see the values? through the sysctl(8) interface — that's where sensor values are made available 🫶

ngl if you're the type to obsess over thermals (and honestly? same), sysctl(8) is the group chat where the numbers show up.

💀 reminder bestie: the sensor values are available through the sysctl(8) interface. that's it. that's the whole access path. don't go looking for a fancier one.
