bind_previous_governor(9)

💅 bind_previous_governor(9) — the "oops bestie, put it back" era

okay so like, quick vibe check: this is a page from the Kernel API Manual (manual section 9, the kernel-flavoured one 🧚), and it's about thermal zones and governors and honestly it's giving "undo button energy." Let's get into it ✨

---

💖 NAME 💖

bind_previous_governor — bind the previous governor of the thermal zone 🎀

like, you had a governor, it did its job, a new one showed up and fumbled, so we're re-binding the old one. no cap.

---

✨ SYNOPSIS ✨

void bind_previous_governor (struct thermal_zone_device *tz , const char
*failed_gov_name );

so it's a void function, meaning it returns nothing at all, literally nothing, it just does the thing and dips 💅

---

🌸 ARGUMENTS 🌸

• tz — a valid pointer to a struct thermal_zone_device 🫶 (key word: valid — don't be out here passing nonsense, this is the thermal zone we're talking about, she's the main character)
• failed_gov_name — the name of the governor that failed to register 😭💀 like the name tag of the new governor who just didn't make the cut

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: this function registers the previous governor of the thermal zone after a new governor has failed to be bound. periodt.

that's it. that's the whole plot. the new governor fumbled, so we're putting the old one back on the throne 👑 it's giving "we tried something new and it did not slay, so we're reverting."

y'all should also check out the kernel file ./drivers/thermal/thermal_core.c (that's where the magic lives, iykyk) plus all these other iconic functions:

• thermal_set_governor(9)
• thermal_bind_cdev_to_trip(9)
• thermal_unbind_cdev_from_trip(9)
• thermal_cooling_device_register(9)
• devm_thermal_cooling_device_register(9)

• thermal_zone_get_zone_by_name(9)

go read them. or don't. but like, they're right there 🍓

and that's the whole page bestie!! 🎀 this one came straight out of ./drivers/thermal, dated October 2026, and it lives in the Kernel API Manual as bind_previous_governor(9) — mwah, love that for us 💜✨
