✨ intel_dp_tunnel_mgr_init(9) ✨

ok so bestie, we're in the Kernel API Manual today and this one is a whole little function that sets up your DP tunnel manager 💅 it's short, it's sweet, it's giving "one job, done right"

---

🌸 NAME 🌸

intel_dp_tunnel_mgr_init — initialize the DP tunnel manager 🎀

---

🦋 SYNOPSIS 🦋

int intel_dp_tunnel_mgr_init (struct intel_display *display );

like literally that's it, one arg, she's low maintenance ✨

---

💖 ARGUMENTS 💖

• display — the display device 🖥️ (yes that's the whole description, ngl she's not chatty)

---

🧚 DESCRIPTION 🧚

okay so this function initializes the DP tunnel manager 💫 and here's the part where you gotta pay attention bestie: the tunnel manager is gonna support the detection/management of DP tunnels on all DP connectors — like, every single one — so you have to call this function after all those connectors have already been registered 👑 that's not a suggestion, that's the contract fr fr

Return 0 in case of success 🎉 and a negative error code otherwise 😭 (so like, check your return value, don't just vibe past it 🙈)
