genwqe_bus_reset(9)

💅 genwqe_bus_reset — the kernel API manual, bestie edition ✨

okay so real talk, this is genwqe_bus_reset(9) from the Kernel API Manual, and it's genuinely one of the shortest pages ever, but it's giving main character energy because it's literally about bringing a dead card back to life 🫶

---

🌸 NAME 🌸

genwqe_bus_reset — Card recovery 💖

like, the whole vibe of this function is "the card fell over, we're getting it back up."

---

✨ SYNOPSIS ✨

int genwqe_bus_reset (struct genwqe_dev *cd );

that's it, that's the whole signature, no cap 🔥

---

🎀 ARGUMENTS 🎀

• cd — GenWQE device information 💅 the struct carrying all the deets about your device, bestie

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: pci_reset_function will recover the device and make sure the registers are accessible again — but only when it completes with success. 👑

and like… if it doesn't succeed? 😭 the card will stay dead and the registers will be unaccessible still. no glow-up, no comeback, just a brick. so yeah, this one's a little high-stakes ngl 💀

fr fr: the recovery is entirely conditional on pci_reset_function succeeding. no success, no registers, periodt.
