dpu_encoder_...ebus_enabled(9)

🌸 NAME 🌸

dpu_encoder_is_widebus_enabled — returns a bool value that tells you whether widebus is enabled 💅 periodt

So like, this is a page from the Kernel API Manual, section 9, and it's literally just one tiny little function that answers one tiny little question, and honestly? Iconic of it. 🎀

---

✨ SYNOPSIS ✨

bool dpu_encoder_is_widebus_enabled (const struct drm_encoder *drm_enc
);

okay so it hands you back a bool, no cap — that's the whole vibe. 🦋

---

💖 ARGUMENTS 💖

• drm_enc — pointer to a previously created drm encoder structure 🫶 bestie, this needs to be an encoder you already made. Don't come at it with a fresh uninitialized one, that's not the move.

---

👑 SEE ALSO 👑

okay so this is the part where I list literally everything, and I mean everything, because the kernel docs said so and we do not skip. 🙈

The kernel file it lives in: ./drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c 📁 (yes, that whole path, I'm not trimming it, that's her address)

✨ that's the whole page bestie ✨ love u, go check if your widebus is enabled 🧚💜

signed, sealed, delivered from ./drivers/gpu/drm/msm/disp/dpu1, dated October 2026, and yes the page really is called dpu_encoder_...ebus_enabled(9) — she's a little truncated in the header and we love her for it 💅
