💅 igc_io_error_detected 💅

ok so bestie, welcome to the Kernel API Manual, section 9 — yes section nine, the fun one where all the kernel functions live. this page is literally all about igc_io_error_detected, and it's giving "the NIC had a bad day and we need to talk about it" energy 🫶

---

✨ NAME ✨

igc_io_error_detected — called when PCI error is detected 🌸

like, that's the whole job description. a PCI error shows up, this function gets the call. iconic honestly.

---

✨ SYNOPSIS ✨

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

---

🎀 ARGUMENTS 🎀

• pdev — pointer to the PCI device 💖 like, which device are we having feelings about
• state — the current PCI connection state 🦋 the vibe check of the bus at the moment of the oopsie

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕ — this function is called after a PCI bus error affecting this device has been detected. that's it, that's the moment. the error's already been spotted, and now this function gets summoned. main character energy, no cap ✨

not me reading this and going "oh so it's the aftermath handler" — yes bestie, exactly that. after. detected. done. 💅
