dtpm_unregister(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dtpm_unregister(9) — like, the Kernel API Manual, but make it make sense 🎀

okay bestie, so this is dtpm_unregister, and it lives in section 9 of the Kernel API Manual. yes, that section 9. sit down, hydrate, and let's get into it ✨

🌸 SYNOPSIS 🌸

void dtpm_unregister (struct dtpm *dtpm );

that's it. that's the whole vibe. a void return, one pointer, zero drama (until you read the description, lmao 😭).

🦋 ARGUMENTS 🦋

  • dtpm — a pointer to a struct dtpm that corresponds to the node you want removed. like, this is the node that's gotta go. it's the one on the chopping block, the one catching a one-way ticket out of the hierarchy tree 🌈🫶

👑 DESCRIPTION 👑

so what does it actually do, you ask? it calls the underlying powercap unregister function. that's the move. no cap, that's literally the whole job 💅

and then — plot twist — that powercap unregister function will call the release callback of the powercap zone. so yeah, the chain reaction is real. you call this, it calls that, that calls the release callback, and somewhere in there a zone is getting its goodbye hug 🫶✨

it's giving "one function to hand off to another function." iconic delegation behavior, honestly.

heads up, bestie: this is a void function, so there's no return value to check. it does the thing and it's done. don't be out here assigning it to a variable, there's nothing to catch 😌

💜 SEE ALSO 💜

  • the kernel file ./drivers/powercap/dtpm.c — that's home base, go read it, iykyk 📖

and the squad, the whole dtpm friend group:

like, this function is one member of the group chat. you can't just read this one and think you know the whole lore. go read the others too. periodt. 🔥

✨ okay that's the whole page, you ate that 💅 and for the cute sign-off: this page comes from ./drivers/powercap and it's dated October 2026 — yeah, from the future, main character energy fr fr 🦋⭐🎀
