igb_io_error_detected(9)

💅 igb_io_error_detected — like, the whole vibe check

okay bestie, so this page is igb_io_error_detected(9) from the Kernel API Manual — yeah, the Kernel API Manual, we're in the big leagues now 🎀. It's giving driver-internals realness and honestly? Iconic.

✨ NAME ✨

igb_io_error_detected — the function that gets called when a PCI error is detected 🚨💀

🌸 SYNOPSIS 🌸

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

Like, she returns a pci_ers_result_t and she takes two things. That's it. That's the whole signature. Periodt. 👑

🦋 ARGUMENTS 🦋

• pdev — literally just a pointer to the PCI device. That's the device we're talking about. Ngl, she's the main character here.
• state — the current pci connection state. Yep, the state it's in right now. 🙈

💖 DESCRIPTION 💖

So here's the tea: this function gets called after a PCI bus error affecting this device has been detected. Like, the error already happened, the bus already noticed, and then our girl igb_io_error_detected gets the call. It's the "so... now what" function. Lowkey stressful but she handles it. 💅

Fair warning bestie, that's genuinely the entire description. No extra lore, no secret tricks. Just: error detected → function called. 🫶
