💥 wx_io_error_detected(9) 💥

okay so this is a page from the Kernel API Manual — it's wx_io_error_detected(9), bestie, and she's the one who shows up when the PCI bus is having a whole crisis 😭

---

✨ NAME ✨

wx_io_error_detected — literally the function that gets called when a PCI error is detected 🚨

---

🌸 SYNOPSIS 🌸

pci_ers_result_t wx_io_error_detected (struct pci_dev *pdev ,
       pci_channel_state_t state );

---

🎀 ARGUMENTS 🎀

• pdev — a pointer to the PCI device 💅 like, the actual device in question
• state — the current pci connection state, i.e. what kind of situation we're in right now 👀

---

⭐ RETURN ⭐

pci_ers_result_t. that's it, that's the answer 🫶

---

🦋 DESCRIPTION 🦋

So here's the vibe: this function gets called after a PCI bus error affecting this device has been detected. not before, not during — after. the error already happened, and now she's on the scene 🧚✨
