dpu_encoder_vsync_time(9)

💖 dpu_encoder_vsync_time(9) 💖

okay so bestie, welcome to the Kernel API Manual page for dpu_encoder_vsync_time(9) — yes the whole manual is literally named after the function, main character energy fr fr ✨

---

🌸 NAME 🌸

dpu_encoder_vsync_time — get the time of the next vsync 👑

---

✨ SYNOPSIS ✨

int dpu_encoder_vsync_time (struct drm_encoder *drm_enc , ktime_t
*wakeup_time );

like, that's the whole vibe. one function, two args, returns an int. slay.

---

🎀 ARGUMENTS 🎀

• drm_enc — encoder pointer 💅 like, the encoder in question, that's it
• wakeup_time — pointer to ktime_t to write the vsync time to ⏰ so you hand it a spot in memory and it drops the vsync time in there, no cap

little sign-off moment: this one lives in the Kernel file ./drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c, source tree at ./drivers/gpu/drm/msm/disp/dpu1, and it's dated October 2026 📅 — periodt, go read the source, ily, bye 💜
