💫 update_seamless_boot_flags(9) — the Kernel API Manual glow-up 💫

okay so bestie, welcome to the glow-up of update_seamless_boot_flags(9) from the Kernel API Manual ✨ this one is a helper function and honestly? it's giving "small but essential" energy. let's get into it 🫶

---

🌸 NAME 🌸

update_seamless_boot_flags — a helper function for updating seamless boot flags. that's it, that's the whole thing, and she does her job 💅

---

✨ SYNOPSIS ✨

void update_seamless_boot_flags (struct dc *dc , struct dc_state
*context , int surface_count , struct dc_stream_state *stream );

look at that signature. no return value, four arguments, absolute main character energy 👑

---

🎀 ARGUMENTS 🎀

• dc — the current DC state. like, where we're at right now 💖
• context — the new DC state that's about to be programmed. the future, bestie 🌈
• surface_count — the number of surfaces that have an updated. yes, that's exactly how the manpage words it, no cap 🧚
• stream — the corresponding stream to be updated in the current flip. she's the one getting the glow-up in this flip 🔥

---

💜 DESCRIPTION 💜

okay so the tea ☕ — updating seamless boot flags does not need to be part of the commit sequence. not even a little bit.

this helper function will update the seamless boot flags on each flip (if required) outside of the HW commit sequence — whether that's the fast one or the slow one. literally just doing her own thing off to the side, unbothered 💅✨

---

⭐ RETURN ⭐

void — she returns nothing. no value, no drama, just vibes 🦋
