drm_vblank_work_init(9)

💅 drm_vblank_work_init — okay bestie, let's set up a vblank work item ✨

So this is a page from the Kernel API Manual (yes, the kernel has a whole manual, she's got range 🎀), and it's about drm_vblank_work_init(9), which — spoiler — initializes a vblank work item. Iconic. Let's get into it.

---

🌸 SYNOPSIS 🌸

void drm_vblank_work_init (struct drm_vblank_work *work , struct
drm_crtc *crtc , void (*func)(struct kthread_work *work) );

Literally that's the whole signature, copy it exactly, do not @ me 🫶

---

🦋 ARGUMENTS 🦋

• work — the vblank work item. This is the little guy you're setting up 💖
• crtc — the CRTC whose vblank will trigger the work execution. Like, this is the CRTC that gets to be the main character and fire the whole thing off 👑
• func — the work function to be executed. The function that actually does the thing when the vblank hits 🔥

---

✨ DESCRIPTION ✨

Okay so real talk: this function initializes a vblank work item for a specific CRTC. That's the vibe. That's the whole job. One (1) work item, tied to one (1) CRTC. No cap 💅

👀 SEE ALSO 👀

Go read these too, bestie, they're all in their flop era until you do:

• Kernel file ./drivers/gpu/drm/drm_vblank_work.c — the source file itself 🧚
• vblank works(9)
• drm_vblank_work_schedule(9)
• drm_vblank_work_cancel_sync(9)
• drm_vblank_work_flush(9)
• drm_vblank_work_flush_all(9)

🌈 fr fr, that's the entire page. Short, sweet, and lowkey kind of a bop.

That's a wrap, bestie 🍓 — this page lives under ./drivers/gpu/drm and it was dated October 2026, so like… future queen behavior honestly ⭐💜
