genwqe_stop(9)

🎀 genwqe_stop(9) 🎀

okay so bestie, this is a page from the Kernel API Manual — yes, the Kernel API Manual, we're in the big leagues now 💅 — and it's about genwqe_stop, a function whose whole personality is "stop the card, but like, gracefully." Let's get into it 🦋

---

✨ NAME ✨

genwqe_stop — stop card operation, fr fr 👑

---

🌸 SYNOPSIS 🌸

int genwqe_stop (struct genwqe_dev *cd );

---

💖 ARGUMENTS 💖

• cd — the GenWQE device information, like the lil ID card for the card itself 🫶

---

🧚 DESCRIPTION 🧚

okay so first up, the recovery notes, and this part is lowkey important so pay attention 📝

As long as genwqe_thread runs, we might access registers during error data capture. Same energy with genwqe_health_thread — it's also out here touching registers, no cap 😭

And then here's the messy part 💀 when genwqe_bus_reset fails, this function might get called two times: first by the genwqe_health_thread, and later by genwqe_remove to unbind the device. We must be able to survive that. Not just survive it — thrive through it, bestie 🌈

So the whole takeaway: this function must be robust enough to be called twice. That's the vibe check it has to pass, and it has to pass it every single time 🎀
