💅 intel_dp_tunnel_resume 💅

okay so bestie, welcome to the intel_dp_tunnel_resume(9) page from the Kernel API Manual — yes that Kernel API Manual, the one we all live in 🫶. This is the function that gets a DP tunnel back on its feet on a port, and honestly? It's giving "wake up bestie, we're resuming" energy ✨.

🎀 NAME 🎀

intel_dp_tunnel_resume — literally resumes a DP tunnel that's connected on a port. that's it, that's the vibe 💖

---

✨ SYNOPSIS ✨

void intel_dp_tunnel_resume (struct intel_dp *intel_dp , const struct
       intel_crtc_state *crtc_state , bool dpcd_updated );

no cap, it returns void, so nothing comes back — it just does the thing 💅

🦋 ARGUMENTS 🦋

• intel_dp — the DP port object. that's the main character right there 👑
• crtc_state — the CRTC state. iconic, necessary, showing up as always 🌸
• dpcd_updated — a bool, and it's true when the DPCD DPRX capabilities got updated during resume. iykyk 🙈

🌈 DESCRIPTION 🌈

Resume a DP tunnel on intel_dp with BW allocation mode enabled on it. that's the whole assignment, and she ate 🔥
