vb2_core_queue_init(9)

💖 vb2_core_queue_init(9) — Kernel API Manual, but make it group chat 💖

🌸 NAME 🌸

vb2_core_queue_init — initialize a videobuf2 queue. periodt, that’s the gig.

✨ SYNOPSIS ✨

okay so the signature is literally:

int vb2_core_queue_init (struct vb2_queue *q );

yes bestie, the spacing is staying exactly as-is 💅

🎀 ARGUMENTS 🎀

• q — pointer to struct vb2_queue with videobuf2 queue. This structure should be allocated in driver. so like, driver allocation energy.

🦋 DESCRIPTION 🦋

The vb2_queue structure should be allocated by the driver. The driver is responsible for clearing its content and setting initial values for some required entries before calling this function. this is the pre-call checklist, bestie — handle it before you call.

⚠️ NOTE: the following fields at q should be set before calling this function: vb2_queue->ops, vb2_queue->mem_ops, vb2_queue->type.
