🌸 liquidio_pcie_error_detected(9) — aka the "uh oh, PCI said something broke" girly 💅

okay so real talk, bestie — you're reading a page from the Kernel API Manual, and the star of the show is liquidio_pcie_error_detected. It's giving "first responder energy" fr fr. She doesn't fix anything herself, she just knows when things went sideways. Iconic. 👑

✨ NAME ✨

liquidio_pcie_error_detected — literally called when a PCI error is detected 🚨

---

🦋 SYNOPSIS 🦋

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

---

🎀 ARGUMENTS 🎀

• pdev — pointer to the PCI device, like, the actual device in question 🫶
• state — the current pci connection state, so you know what vibe the bus is in 💫

---

🌈 DESCRIPTION 🌈

So here's the tea ☕: this function gets called after a PCI bus error affecting this device has been detected. That's it. That's the whole job. She's the "not me finding out everything is on fire" friend — she shows up once the drama already happened, not before. No cap. 🔥
