CORETEMP(4)

💅 CORETEMP 💅

okay so bestie, welcome to coretemp — the device driver for Intel Core on-die digital thermal sensor. yes she's a kernel interface manual, yes she's iconic, no we are not skipping a single detail. let's get into it 🫶

---

✨ SYNOPSIS ✨

so like, if you want to compile this driver directly into the kernel (main character move tbh), you gotta place this line in your kernel configuration file:

device coretemp

alternatively — and this is the lowkey easier route, ngl — you can load the driver as a module at boot time. to do that, place this line in loader.conf(5):

coretemp_load="YES"

no cap, that's it. two little lines and you're so back 🌸

---

🦋 DESCRIPTION 🦋

the coretemp driver provides support for the on-die digital thermal sensor present in Intel Core and newer CPUs. literally it's the vibe check for your silicon 🔥

and the way that it works?? the coretemp driver reports each core's temperature through a sysctl node in the corresponding CPU device's sysctl tree, named:

dev.cpu.%d.temperature

periodt. every core gets its moment. go off 👑

🎀 SEE ALSO 🎀

• amdtemp(4)
• sysctl(8)

like yes, go read those too, iykyk 💜

🌈 HISTORY 🌈

the coretemp driver first appeared in FreeBSD 7.0. vintage. a classic. we stan a legacy icon ⭐

👑 AUTHORS 👑

the coretemp driver was written by Rui Paulo <rpaulo@FreeBSD.org> as part of a Google Summer of Code project. slay, genuinely.

this manual page was written by Dag-Erling Smørgrav <des@FreeBSD.org>. iconic behaviour from both of them fr fr 🧚
