ice_pci_sriov_ena(9)

💅 ice_pci_sriov_ena — Kernel API Manual ✨

okay so bestie, welcome to ice_pci_sriov_ena(9) 🎀 — this is a page from the Kernel API Manual and it's literally all about flipping on SR-IOV and/or changing how many VFs you're rolling with. no cap, it's a short one, but it's iconic for what it does. 🦋

---

🌸 SYNOPSIS 🌸

int ice_pci_sriov_ena (struct ice_pf *pf , int num_vfs );

like, that's the whole signature. so clean. 💅

---

💖 ARGUMENTS 💖

• pf — a pointer to the PF structure, aka the Physical Function. that's your main character, the parent of all the VFs. 👑
• num_vfs — the number of VFs you wanna allocate. this is the "how many little besties am I spawning" number. 🫶

---

🔥 DESCRIPTION 🔥

so what does it return, you ask? it's giving:

• 0 on success ✨ — slay, it worked.
• negative on failure 💀 — not slay, something went sideways.

and that's genuinely it fr fr. no extra lore in this one, that's the whole description. 🙈

---

🌈 SEE ALSO 🌈

okay so this list is LONG and honestly kind of iconic — every single one of these is a sibling function in the ice family, and you should absolutely go read them if you're doing SR-IOV stuff. iykyk. 🧚
