intel_dp_tun...ar_stream_bw(9)

✨ NAME ✨

intel_dp_tunnel_atomic_clear_stream_bw — bestie, this is the one that clears any DP tunnel stream BW requirement 💅

(also hiiii, welcome to the Kernel API Manual, we're literally in the kernel docs rn 🫶)

---

🌸 SYNOPSIS 🌸

int intel_dp_tunnel_atomic_clear_stream_bw (struct intel_atomic_state
*state , struct intel_crtc_state *crtc_state );

okay so that's the whole vibe — one int in, two structs, no cap 🎀

---

🦋 ARGUMENTS 🦋

• state — the atomic state, periodt. That's the whole thing, it's the atomic state 😌
• crtc_state — the state of the CRTC of the given DP tunnel stream. like, that CRTC's state, the one attached to the DP tunnel stream we're talking about ✨

---

💜 DESCRIPTION 💜

So the way that this works: it clears any DP tunnel stream BW requirement that got set by intel_dp_tunnel_atomic_compute_stream_bw. That's it, that's the job. Undo the BW requirement, clean slate, fresh start, main character energy 🌈

It returns 0 in case of success, and a negative error code otherwise. ngl if you see a negative number just know it did not slay 😭

quick vibe check: this page lives in ./drivers/gpu/drm/i915/display, dated October 2026, and it's intel_dp_tun...ar_stream_bw(9) — yeah the title got truncated, it's a whole thing, we don't talk about it 💀 anyway mwah, go clear those stream BW requirements, ily, bye 🍓🧚💜
