vb2_queue_init_name(9)

💖 vb2_queue_init_name(9) 💖

okay so welcome to the Kernel API Manual, bestie — today's main character is vb2_queue_init_name(9) and honestly? she's iconic, she's lowkey just vb2_queue_init with a little name tag, and we're gonna stan. ✨

---

🎀 NAME 🎀

vb2_queue_init_name — initialize a videobuf2 queue with a name. that's it, that's the vibe check. 💅

---

✨ SYNOPSIS ✨

int vb2_queue_init_name (struct vb2_queue *q , const char *name );

like literally copy that, don't @ me 🙈

---

🌸 ARGUMENTS 🌸

• q — pointer to struct vb2_queue with videobuf2 queue. this is your queue, your girl, your responsibility 🫶
• name — the queue name. give her a name, she deserves one 🎀

---

🦋 DESCRIPTION 🦋

okay so here's the tea: this function initializes the vb2_queue exactly like vb2_queue_init, and additionally sets the queue name. no cap, same energy, just plus a name. 🧚

the queue name is used for logging purposes, and it should uniquely identify the queue within the context of the device it belongs to. (yes, uniquely — she's not out here sharing names with anyone, main character energy only 👑)

why do we care? because it's useful to attribute kernel log messages to the right queue for m2m devices or other devices that handle multiple queues. imagine trying to read your group chat with no sender names — that's the nightmare we're avoiding. 😭💀
