✨ intel_dp_tunnel_atomic_check_state(9) ✨

okay bestie, welcome to the Kernel API Manual page for intel_dp_tunnel_atomic_check_state(9) — yes, the name is a whole mouthful, but she's iconic and she knows it. 💅

✨ NAME ✨

intel_dp_tunnel_atomic_check_state — check a connector's DP tunnel specific state. 🎀

🌸 SYNOPSIS 🌸

int intel_dp_tunnel_atomic_check_state (struct intel_atomic_state *state
, struct intel_dp *intel_dp , struct intel_connector *connector );

💅 ARGUMENTS 💅

• state — the atomic state, aka the big state object holding the scene together. ✨
• intel_dp — the DP port object, the port's main character energy. 👑
• connector — the connector that's using intel_dp, bestie. 🫶

🦋 DESCRIPTION 🦋

So here's the vibe: this function checks the DP tunnel atomic state for intel_dp/connector and adds it to state when either of these is true: there's a DP tunnel detected on intel_dp with BW allocation mode enabled on it, or intel_dp/connector was previously enabled via a DP tunnel. 🌈

It returns 0 in case of success, or a negative error code otherwise. No cap. ✨
