qman_start_using_portal(9)

💖 qman_start_using_portal(9) — bestie edition 💖

okay so this page is from the Kernel API Manual, and it's about qman_start_using_portal(9) — literally the function that does the hand-holding between a portal and the device that's about to use it 🫶 no cap.

---

✨ NAME ✨

qman_start_using_portal — register a device link for the portal user 🌸

---

🎀 SYNOPSIS 🎀

int qman_start_using_portal (struct qman_portal *p , struct device *dev
);

like, that's the whole signature, cute and short 💅

---

🦋 ARGUMENTS 🦋

• p — the portal that will be in use ✨ (this is the portal, the main character)
• dev — the device that will use the portal 🔥 (the one doing the using)

---

🌈 DESCRIPTION 🌈

okay so here's the vibe: this function makes sure that the devices that use the portal are unbound when the portal is unbound 😭 it's giving "we go down together" energy — the device link stays honest so nobody's left hanging when the portal gets unbound. periodt. 👑
