🦋 hisi_qm_sriov_disable(9) — disable virtual functions 🦋

okay bestie, welcome to the Kernel API Manual page for hisi_qm_sriov_disable. It’s giving “turn off the virtual functions” energy, and we’re gonna read it together, no cap 💅

---

✨ NAME ✨

hisi_qm_sriov_disable - disable virtual functions

---

🌸 SYNOPSIS 🌸

int hisi_qm_sriov_disable (struct pci_dev *pdev , bool is_frozen );

---

💖 ARGUMENTS 💖

• pdev — the PCI device. literally the PCI device, bestie 🫶
• is_frozen — true when all the VFs are frozen. that’s the whole vibe check ❄️

---

🎀 DESCRIPTION 🎀

okay so here’s the tea: this function returns failure if there are VFs assigned already, or if VF is in used. that’s it — no extra lore, no invented behaviour, periodt 💀
