dpu_encoder_..._commit_done(9)

💅 dpu_encoder_..._commit_done(9) 💅

🌸 NAME 🌸

okay bestie, this is the Kernel API Manual entry for dpu_encoder_wait_for_commit_done — wait for encoder to flush pending state. periodt 💖

---

✨ SYNOPSIS ✨

no edits, no games — here's the signature exactly as it is:

int dpu_encoder_wait_for_commit_done (struct drm_encoder *drm_enc );

---

🎀 ARGUMENTS 🎀

• drm_enc — encoder pointer. that's the whole argument, bestie 🫶

---

🦋 DESCRIPTION 🦋

okay so the vibe is: wait for hardware to have flushed the current pending changes to hardware at a vblank or CTL_START ✨

physical encoders will map this differently depending on the type: vid mode -> vsync_irq, cmd mode -> CTL_START. lowkey iconic how it just switches up like that 💅

---

🌈 RETURN 🌈

• 0 on success 🎉
• -EWOULDBLOCK if already signaled 👀
• error otherwise 😭
