πŸ’… dpll_device_unregister(9)

okay so this is a page from the Kernel API Manual, section 9, and it's literally all about saying bye-bye to a dpll device πŸ‘‹ Bestie, it's a one-function wonder and honestly? iconique.


✨ NAME ✨

dpll_device_unregister β€” unregister dpll device πŸŽ€

Like, the whole job. That's it. That's the gig.


πŸ¦‹ SYNOPSIS πŸ¦‹

void dpll_device_unregister (struct dpll_device *dpll , const struct
       dpll_device_ops *ops , void *priv );

no cap, that's the exact signature β€” three args, returns void (so it gives you nothing back, very mysterious of it πŸ’…).


🌸 ARGUMENTS 🌸

  • dpll β€” the registered dpll pointer. key word: registered. it's the one you already got going, bestie 🫢
  • ops β€” ops for a dpll device. yeah. the ops. for the dpll device. iykyk ✨
  • priv β€” pointer to private information of owner. that's your stuff, the owner's little secret stash πŸ™ˆ

πŸ’– DESCRIPTION πŸ’–

So what does it actually do? It unregisters the device β€” makes it unavailable for userspace. that's the whole vibe check: userspace can't see it anymore, it's off the guest list πŸ’€βœ¨


πŸ‘‘ NOTE πŸ‘‘

⚠️ It does not free the memory. Like, at all. not even a little. so do not come for this function when your memory's still sitting there, she is NOT the cleanup crew 😭

πŸ”₯ CONTEXT πŸ”₯

Acquires a lock (dpll_lock). so yeah, she locks before she does her thing β€” main character energy, very "don't interrupt me" πŸ”’πŸ’…


🌈 SEE ALSO 🌈

Kernel file ./drivers/dpll/dpll_core.c β€” go read the source, bestie, it's giving lore πŸ“–

that's the whole friend group fr fr 🀝
