igbvf_io_slot_reset(9)

💅 igbvf_io_slot_reset 💅

okay so bestie, this is a page from the Kernel API Manual — igbvf_io_slot_reset(9), and it's literally one of the most "we just survived a bus reset" functions ever. no cap. let's get into it ✨

---

✨ NAME ✨

igbvf_io_slot_reset — the function that gets called after the pci bus has been reset. yes that's it. that's the whole vibe. 🫶

---

✨ SYNOPSIS ✨

pci_ers_result_t igbvf_io_slot_reset (struct pci_dev *pdev );

---

✨ ARGUMENTS ✨

• pdev — a pointer to the PCI device. that's your card, your main character, the whole reason we're here 💖

---

✨ DESCRIPTION ✨

so what does it actually do? it restarts the card from scratch — like, fully from a cold-boot, as if the thing just got unplugged and plugged back in. no memory of its past life. clean slate. iconic behavior honestly 🌸

and the implementation? it's giving… the first-half of the igbvf_resume routine. that's the vibe. literally the same energy, just the first half of it. iykyk 💅

ngl this is the recovery arc after the pci bus had a whole meltdown. the card wakes up like "who am i? where am i?" and we rebuild it from zero 🦋
