dpu_encoder..._for_kickoff(9)

💖 dpu_encoder..._for_kickoff(9) 💖

okay bestie, so this little cutie lives in the Kernel API Manual (section 9, kernel-space royalty 👑) and its whole name is dpu_encoder_phys_wb_prepare_for_kickoff — but the page header keeps it short with dpu_encoder..._for_kickoff(9). literally the ellipsis is doing main character work there 💅

---

✨ NAME ✨

dpu_encoder_phys_wb_prepare_for_kickoff — pre-kickoff processing 🎀

---

🦋 SYNOPSIS 🦋

void dpu_encoder_phys_wb_prepare_for_kickoff (struct dpu_encoder_phys
*phys_enc );

that's it, that's the whole vibe — one function, void, one pointer argument, no cap ✨

---

🌸 ARGUMENTS 🌸

• phys_enc — pointer to the physical encoder, bestie 🫶 that's the thing you're handing over. it's a struct dpu_encoder_phys * and it is, quite literally, the physical encoder. slay.

---

⭐ RETURN ⭐

Zero on success 💖 (yes the page says it returns zero even though the signature says void — we are reporting the facts exactly as written, no editing, periodt 🙈🔥)
