igb_io_slot_reset(9)

💅 igb_io_slot_reset(9) — like, the Kernel API Manual page, bestie

okay so picture this: it's the Kernel API Manual, and this one little function is the "we just got PCI-reset, time to wake up" moment. It's called igb_io_slot_reset, and yes it's giving main-character energy in the error-recovery arc 🦋

---

🌸 NAME 🌸

igb_io_slot_reset — the one that gets called after the pci bus has been reset. no cap, that's literally the job description 💅

---

✨ SYNOPSIS ✨

pci_ers_result_t igb_io_slot_reset (struct pci_dev *pdev );

---

🎀 ARGUMENTS 🎀

• pdev — pointer to the PCI device. that's your girl. the card in question 🫶

---

💖 DESCRIPTION 💖

So what does it do? It restarts the card from scratch, as if from a cold-boot — like ripping the plug and plugging it back in, except polite and in-kernel. 🔥

And the implementation? Lowkey iconic: it resembles the first-half of the __igb_resume routine. so it's not reinventing the wheel, it's just doing the opening number of the whole resume choreography. slay 🌈
