ENUM DPU_CRTC_SMMU_STATE_TRANSITION_TYPE(9)

💅 enum dpu_crtc_smmu_state_transition_type(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for enum dpu_crtc_smmu_state_transition_type(9) (the fancy header up top shortens it to enum dpu_crt...nsition_type(9), no cap, that's literally just how it's printed 🫶). It's the enum that says when an SMMU state transition type should happen, and honestly? it's giving extremely specific but extremely important 💖

---

🌸 NAME 🌸

enum dpu_crtc_smmu_state_transition_type — it's a state transition type. that's the whole vibe. 🎀

---

⭐ SYNOPSIS ⭐

here's the whole thing, typed out exactly so you don't have to squint at it:

enum dpu_crtc_smmu_state_transition_type {
    NONE ,
    PRE_COMMIT ,
    POST_COMMIT

};

like, that's it. three (3) little constants, three (3) little moods. 👑

---

🔥 Constants 🔥

okay so every member, one by one, with the exact meaning — no guessing, no vibes-based interpretation, this is the real tea ☕:

• NONE — no pending state transitions. nothing's queued, nothing's waiting, it's a clean slate, we love that for her 🌸
• PRE_COMMIT — state transitions should be done before processing the commit. so like, do the thing first, then handle the commit. order matters bestie 😭
• POST_COMMIT — state transitions to be done after processing the commit. the commit goes first, the transition comes after. iconic sequencing behavior 💅

and that's the page!! 🧚 mwah 💜 this little legend lives over in ./drivers/gpu/drm/msm/disp/dpu1, dated October 2026, and its footer spells the name enum dpu_crt...nsition_type(9) — so if you cite it, cite it cute. periodt. 💖✨🍓
