ice_sriov_configure(9)

💖 ice_sriov_configure(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for ice_sriov_configure(9) — yes it's a real function name and yes it's a mouthful, we're slaying anyway 🫶

---

✨ NAME ✨

ice_sriov_configure — the girl who turns VFs on, or changes how many of them there are, all via sysfs 💅

---

🌸 SYNOPSIS 🌸

int ice_sriov_configure (struct pci_dev *pdev , int num_vfs );

---

🎀 ARGUMENTS 🎀

• pdev — a pointer to a pci_dev structure. literally just the PCI device we're doing all this to 🦋
• num_vfs — how many VFs you wanna allocate, or 0 if you're freeing VFs (bye bye VFs 👋)

---

💜 DESCRIPTION 💜

so this function gets called when the user goes and updates the number of VFs in sysfs. main character of the VF-count-update moment, no cap.

on success? it returns whatever num_vfs was set to by the caller. ate and left no crumbs ✨

on failure? it returns a negative value. not slay. 😭
