drm_dp_remove_payload_part1(9)

💅 drm_dp_remove_payload_part1(9) — like, the Kernel API Manual, but make it make sense 🎀

okay bestie, welcome to the Kernel API Manual ✨ (that's the manual name, we're folding it in, you're welcome 💖). Today's main character is drm_dp_remove_payload_part1 — and yes she is literally part one, the sequel's in SEE ALSO, iykyk 🦋

✨ NAME ✨

drm_dp_remove_payload_part1 — Remove an MST payload along the virtual channel 🌈

Like, she removes. An MST payload. Along the virtual channel. That's the whole vibe check, no cap 💅

---

🌸 SYNOPSIS 🌸

void drm_dp_remove_payload_part1 (struct drm_dp_mst_topology_mgr *mgr ,
struct drm_dp_mst_topology_state *mst_state , struct
drm_dp_mst_atomic_payload *payload );

three args, one void return, no drama 🫶

---

💜 ARGUMENTS 💜

• mgr — Manager to use. literally the topology manager, the big boss of the whole MST situation 👑
• mst_state — The MST atomic state. the state, the moment, the ~atomic~ era 🦋
• payload — The payload to remove. yeah. that payload. she's getting removed 🎀

---

🔥 DESCRIPTION 🔥

So here's what's going down 💀 — drm_dp_remove_payload_part1 removes a payload along the virtual channel if it was successfully allocated. Key detail bestie, don't skip it: if. Conditional queen 🙈

After calling this, the driver should set HW to generate ACT and then switch to new payload allocation state ✨ That's the follow-up, that's the part two energy, don't forget it 🫶

note: this is part1, so like, the removal isn't the whole story — the hardware step comes after, okay? 😭

cute little sign-off because we stan attribution: this one's from ./drivers/gpu/drm/display, dated October 2026, and it's filed under drm_dp_remove_payload_part1(9) — go forth and remove those payloads, periodt 👑🔥
