vb2_queue_init(9)

💅 vb2_queue_init(9) — like, the glow-up ritual for your videobuf2 queue ✨

Okay so real talk, bestie: this is vb2_queue_init(9) from the Kernel API Manual, and it's the little setup moment that makes your videobuf2 queue, y'know, exist properly. Let's get into it 🫶

---

✨ NAME ✨

vb2_queue_init — initialize a videobuf2 queue. That's it, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

int vb2_queue_init (struct vb2_queue *q );

---

🦋 ARGUMENTS 🦋

• q — a pointer to a struct vb2_queue that's holding your videobuf2 queue. That's the thing we're blessing today 💖

---

👑 DESCRIPTION 👑

So here's the tea ☕ — the vb2_queue structure is allocated by the driver. Not us, not the framework, you, the driver author. Main character responsibility, honestly.

And on top of allocating it, the driver is also the one responsible for clearing its content and setting initial values for some required entries before calling this function. So like, do your skincare routine before the photo, y'know? 🌈

Now, the mandatory entries — write these down, no cap:

• q->ops — required, fr fr
• q->mem_ops — also required, don't skip it
• q->type — mandatory, periodt
• q->io_modes — yes, mandatory too

Lowkey everything else you might wanna know lives in the struct vb2_queue description over in include/media/videobuf2-core.h — go read it, it's giving reference material 💅
