igbvf_io_error_detected(9)

💅 igbvf_io_error_detected — like, the whole page, bestie

okay so this is a page from the Kernel API Manual, and the star of the show is igbvf_io_error_detected. Yes, that name is a mouthful, no, we're not shortening it, it's iconic as-is. 🫶

✨ NAME ✨

igbvf_io_error_detected — literally the function that gets called when a PCI error is detected. that's it, that's the vibe check. 💀

---

🌸 SYNOPSIS 🌸

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

look at her go. two arguments, one return type, zero notes. slay. ✨

---

🎀 ARGUMENTS 🎀

• pdev — pointer to the PCI device. it's a struct pci_dev *, so like, give her the actual address, not a vibe. 📍
• state — the current pci connection state, type pci_channel_state_t. this is where the card's head is at right now. 🧠

---

🦋 DESCRIPTION 🦋

so picture this: a PCI bus error happens, and it's affecting this device specifically. once that's been detected, this function is the one that gets called. that's the whole thing. no extra lore, no secret side quests — it fires after the error has been detected, periodt. 🔥

ngl the description is short but she said what she said. 💅
