qede_io_error_detected(9)

💅 qede_io_error_detected — like, the Kernel API Manual (section 9) page you didn't know you needed 🎀

okay bestie, so this is qede_io_error_detected, and it lives in the Kernel API Manual, section 9. Yes, section 9. We love a niche little corner of the docs, no cap. 🦋

✨ NAME ✨

qede_io_error_detected — this is the function that gets called when a PCI error is detected. That's it, that's the whole vibe check. 💅

---

🌸 SYNOPSIS 🌸

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

literally the whole signature, copy it exactly, do not come for me about the spacing, that's how it's written in the source, periodt. 🫶

---

🧚 ARGUMENTS 🧚

• pdev — pointer to the PCI device. like, the device. main character energy, honestly. 👑
• state — the current pci connection state. that's the state of the pci connection, bestie, keep up. 💀

---

⭐ RETURN ⭐

pci_ers_result_t. that's the return type, and it's giving "I return a value and you should probably care about it". no extra details given, so I'm not gonna invent any, iykyk. 🍓

---

🌈 DESCRIPTION 🌈

okay so here's the tea: this function is called after a PCI bus error affecting this device has been detected. not before, not during — after. the error detection already happened, and now this lil function gets its moment. 💖

think of it as the "so... that happened" function. the bus errored, the device is affected, and this is where you land. slay. 🔥

---

💜 SEE ALSO 💜

the kernel file, in all its glory:

./drivers/net/ethernet/qlogic/qede/qede_main.c

go read it, bestie, that's where the actual code lives. 🎀

---

lowkey a reminder: the original page doesn't say anything else about behaviour, side effects or error handling, so I'm not gonna make stuff up. facts only, always. ✨

---

alright, that's the page!! 🌸 this one came from the source path ./drivers/net/ethernet/qlogic/... and it's dated October 2026, so yeah, it's a whole little time capsule, and now you know everything the manpage knows. mwah, bye! 💅🎀🦋
