genwqe_err_error_detected(9)

📦 version 7.3.1, in nixpkgs unstable

💅 genwqe_err_error_detected(9) — like, the Kernel API Manual page your bestie actually wants to read 🎀

Okay so bestie, welcome to the genwqe_err_error_detected page from the Kernel API Manual — yes that's the manual name, we're not copying the header line, we're being cute about it. This one is short and iconic, ngl, so let's get into it ✨

🌸 NAME 🌸

genwqe_err_error_detected — the error detection callback. That's it, that's the whole vibe check 💅

🦋 SYNOPSIS 🦋

pci_ers_result_t genwqe_err_error_detected (struct pci_dev *pci_dev ,
pci_channel_state_t state );

Fr fr, that's the signature — copy it exactly, don't be out here renaming stuff 🙈

✨ ARGUMENTS ✨

  • pci_dev — the PCI device information struct. Like, the whole little ID card for your device 🫶
  • state — the PCI channel state. It's giving "what's the situation rn" energy 👑

🔥 DESCRIPTION 🔥

So here's the tea: this callback gets called by the PCI subsystem whenever a PCI bus error is detected. That's literally the entire description and honestly? Short king behavior. No cap, that's all it does — PCI subsystem says "oops, bus error," and this callback gets the call ☎️💀
