capture_urb_complete(9)

okay bestie, we’re in the Kernel API Manual for capture_urb_complete(9) 🎀 — buckle up, this one’s short but iconic.

✨ NAME ✨

capture_urb_complete — Completion handler for capture bulk URBs. 💖

🦋 SYNOPSIS 🦋

void capture_urb_complete (struct urb *urb );

that’s the whole signature, no cap ✨

🎀 ARGUMENTS 🎀

• urb — the completed URB 🌸

💅 DESCRIPTION 💅

okay so here’s the vibe: this function runs in interrupt context 😭. It copies the received raw data into an intermediate ring buffer and then schedules the workqueue to process it. It then resubmits the URB to receive more data. Literally the whole little pipeline: copy the raw data, buffer it, schedule the workqueue, resubmit. Iconic. 👑
