octep_probe(9)

💖 octep_probe(9) — like, the Octeon PCI device probe handler, bestie 💖

okay so real talk, this one lives in the kernel API manual (octep_probe(9)) and it's the moment a brand-new Octeon PCI device gets its whole life together. buckle up 🎀

---

✨ NAME ✨

octep_probe — the Octeon PCI device probe handler, no cap. it's the literal main character that shows up when a device gets detected 💅

---

🌸 SYNOPSIS 🌸

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

like… it returns an int, that's the vibe check right there ⭐

---

🦋 ARGUMENTS 🦋

• pdev — the PCI device structure itself. literally the device, the whole device, nothing but the device 🫶
• ent — an entry in the Octeon PCI device ID table. it's the little name tag telling everyone which device this is iykyk

---

🔥 DESCRIPTION 🔥

so what does it actually do? glad you asked 💖

It initializes and enables the Octeon PCI device for network operations. that's the whole point, that's the assignment, and it ate. ✨

It also initializes the Octeon private data structure (gotta have somewhere to keep your stuff 🎀) and registers a network device. so by the end of it, the device is out here living its best network-interface life. periodt.

💀 friendly reminder bestie: this page is about octep_probe specifically — I'm not out here inventing behavior, just telling you what the manual says. if you need the details of any of those friends up there, go read their pages. iykyk 🎀

and that's the whole page!! 🌈 this one came from ./drivers/net/ethernet/marvell... (that's the truncated source/version line, they really said "…" and dipped 💀) and it's dated October 2026. thanks for reading my little kernel TED talk, ily, go probe something 💜✨🦋
