iavf_probe(9)

💅 iavf_probe(9) — like, the actual manual page, section 9 of the Kernel API Manual, bestie 🎀

okay so real talk, this page is iavf_probe from the Kernel API Manual, section 9, and it's basically the origin story of your network adapter 💖 it's short, it's sweet, and every single detail matters, so let's get into it.

---

✨ NAME ✨

iavf_probe — Device Initialization Routine 🌸

like... the routine where the device gets born, iykyk.

---

🦋 SYNOPSIS 🦋

int iavf_probe (struct pci_dev *pdev , const struct pci_device_id *ent
);

it hands back an int, bestie. that's the vibe check right there. 👑

---

💜 ARGUMENTS 💜

• pdev — the PCI device information struct 🫶 like, the little ID card for the piece of hardware we're about to wake up.
• ent — the entry in iavf_pci_tbl ✨ the matching-table moment. it's giving "yes, you, you're the one."

---

🔥 DESCRIPTION 🔥

Returns 0 on success, negative on failure. no cap, that's the whole contract 😭 zero means slay, anything negative means we're not okay.

iavf_probe initializes an adapter identified by a pci_dev structure. it literally finds the adapter, looks at it, and goes "you're coming with me." 💅

and then three big things happen, all of which are iconic in their own right:

1. The OS initialization 🎀
2. Configuring of the adapter private structure 🧚
3. A hardware reset 💀 (yes, the dramatic part — it resets the hardware, that's not a metaphor)

so like, this one function does the OS handshake, sets up the adapter's private struct, and then hits the hardware with a reset. main character energy, honestly. 🌈

so yeah, that's iavf_probe 💖 short page, big job, zero notes. go read the source file, bestie, it's right there in ./drivers/net/ethernet/intel/iavf/iavf_main.c. 🫶

this icon of a manual page came from ./drivers/net/ethernet/intel/iavf (that's the source/version bit 🌸) and is dated October 2026 — yes, the future, she's early 👑 — and the whole thing is iavf_probe(9), bye bestie 🎀✨
