💅 commit_minimal_transition_state — Kernel API Manual (section 9, bestie)

okay so real talk, this is the man page for commit_minimal_transition_state, straight out of the Kernel API Manual, and it's honestly lowkey iconic. it's giving "my code has trust issues and needs a middle step" energy and tbh? same.

---

✨ NAME ✨

commit_minimal_transition_state — create a transition pipe split state 🎀

---

🌸 SYNOPSIS 🌸

bool commit_minimal_transition_state (struct dc *dc , struct dc_state
*transition_base_context );

no cap, that's the whole signature. it returns a bool, it takes two pointers, slay.

---

🦋 ARGUMENTS 🦋

• dc — you pass this in to get the current state status. yeah it's the plug for state info 💖
• transition_base_context — the new transition state. that's the whole vibe of it ✨

---

💫 DESCRIPTION 💫

okay so storytime. in some specific configurations — think pipe split on multi-display with MPO and/or Dynamic ODM — removing a plane can straight up cause unsupported pipe programming when you move to new planes. like, the hardware just says "no ❤️" and you're standing there like 😭.

to mitigate those types of problems, this function adds a transition state that minimizes pipe usage before programming the new configuration. so it's the responsible bestie that goes "hold on, let's not rush into this" 🙈.

here's the tea on how it plays out:

• when adding a new plane — the current state requires the least pipes, so it's applied without splitting.
• when removing a plane — the new state requires the least pipes, so it's applied without splitting.

literally the least-pipes-possible agenda in both directions. periodt. 👑

---

🔥 RETURN 🔥

returns false if something is wrong in the transition state. so like, if you get a false back, something's off — vibe check failed 💀.

lowkey a warning-ish note from me to you: this page lives at ./drivers/gpu/drm/amd/display/... and it's dated October 2026 in the footer, so that's the source/version energy right there 🫶

and that's the page bestie!! mwah 💋 — signed off with ./drivers/gpu/drm/amd/display/..., October 2026, commit_mini...sition_state(9) ✨🌈⭐
