agp_backend_release(9)

🌸 agp_backend_release(9) — Kernel API Manual 🌸

okay so bestie, welcome to the Kernel API Manual page for agp_backend_release(9) — yes that's the whole title, we're keeping it 💅

---

✨ NAME ✨

agp_backend_release — release the lock on the agp backend 🎀

---

✨ SYNOPSIS ✨

void agp_backend_release (struct agp_bridge_data *bridge );

literally that's it. one function, one argument, no return value, no drama 🔥

---

✨ ARGUMENTS ✨

• bridge — the AGP backend you're releasing, bestie. that's the one. 🫶

---

✨ DESCRIPTION ✨

okay so here's the vibe check 👑 — as the caller, you are responsible for making sure the graphics aperture translation table is sorted out before anyone else touches it. the manpage puts it like this, and we're keeping it word for word because this is not the place to be creative:

"The caller must insure that the graphics aperture translation table is read for use by another entity."

and then, lowkey the most important bit 🙈:

"(Ensure that all memory it bound is unbound.)"

so yeah — unbind everything you bound before you hand it off. no cap, if you skip that step that's on you, not on the function 💀

✨ SEE ALSO ✨

• Kernel file ./drivers/char/agp/backend.c — go read the source bestie, it's giving main character energy 📖
• agp_backend_acquire(9) — the flip side of the coin, the grab the lock counterpart 🌈

and that's the whole page, no notes ✨
