adf_sriov_configure(9)

💅 adf_sriov_configure(9) — the Kernel API Manual era 🎀

okay so bestie, welcome to adf_sriov_configure(9), a page from the Kernel API Manual. it's short, it's sweet, and it's lowkey iconic — let's get into it 💖

---

✨ NAME ✨

adf_sriov_configure — literally the function that enables SRIOV for the device, no cap 🦋

---

🌸 SYNOPSIS 🌸

int adf_sriov_configure (struct pci_dev *pdev , int numvfs );

that's the whole signature, side-eye to the spacing, we keep it exactly as it is ✨

---

🫶 ARGUMENTS 🫶

• pdev — a pointer to the PCI device. just a pointer, pointing at a PCI device, doing its little pointer thing 💅
• numvfs — the number of virtual functions (VFs) to enable. hold that thought tho…

---

🔥 DESCRIPTION 🔥

so here's the plot twist, bestie: the numvfs parameter gets ignored. yeah, you heard me. 🙈 it doesn't matter what number you hand over because of the design of the hardware — all the VFs that the device supports get enabled. every single one. the hardware said "all of them" and honestly? slay 👑

and the main character job of this function: it enables SRIOV for the PCI device. that's it. that's the whole vibe check 🧚

---

👑 RETURN 👑

on success you get back the number of VFs enabled — yes, it returns a number, so go ahead and actually read it 😭 — and on failure you get an error code. so basically: number = good, error code = not good. iykyk 💀

🌈 SEE ALSO 🌈

• Kernel file ./drivers/crypto/intel/qat/qat_common/adf_sriov.c — go read the source, it's giving lore 🍓
• adf_disable_sriov(9) — the one that turns it back off, the breakup arc 💔

---

fr fr: don't pass numvfs and expect it to mean something. the hardware runs the show here, not you, and not your cute little integer 🌸
