intel_modese...l_pipes_late(9)

💅 intel_modeset_all_pipes_late

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs for fun now, that's the era we're in 🎀 this one lives in section 9 (that's the kernel API section, iykyk) and it's called intel_modeset_all_pipes_late.

---

✨ NAME ✨

intel_modeset_all_pipes_late — literally just force a full modeset on all pipes. that's the whole vibe. no cap. 🔥

---

🌸 SYNOPSIS 🌸

int intel_modeset_all_pipes_late (struct intel_atomic_state *state ,
const char *reason );

like… it returns an int, it takes state and reason, that's it, she's lowkey simple 💖

---

🦋 ARGUMENTS 🦋

• state — the intel atomic state 🫶 this is the whole situation we're working with
• reason — the reason for the full modeset 💀 yes bestie, you have to say why. the function wants the lore.

---

👑 DESCRIPTION 👑

okay so here's what she does: she adds all the pipes to state, and then forces a full modeset on the active ones — and the whole "why are we doing this" energy comes straight from whatever you put in reason. 📝

🚨 important caveat, do NOT skip this: this function can be called only after new plane states are computed already. that's not a suggestion, that's the rule. call her too early and it's giving chaos. 😭

Returns: 0 in case of success, negative error code otherwise. simple as that, iconic behaviour honestly 💅
