ctucan_pci_probe(9)

💅 ctucan_pci_probe — like, the PCI registration call bestie ✨

okay so this is ctucan_pci_probe(9) from the Kernel API Manual and honestly? she's a whole vibe. sit down, grab a strawberry drink 🍓, and let me tell you about the function that gets your CAN device registered with PCI. no cap, it's important.

---

🌸 SYNOPSIS 🌸

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

that's the whole signature, copy it exactly, don't come for me about the spacing, that's literally how it is 💀

---

🎀 ARGUMENTS 🎀

• pdev — handle to the pci device structure. it's giving "here's the device, do something with it" energy 🫶
• ent — pointer to the entry from ctucan_pci_tbl. yes, that exact table, keep the name, iykyk ✨

---

🦋 DESCRIPTION 🦋

okay so this function is the main character 🔥 — it does all the memory allocation and registration for the CAN device. like, all of it. the allocating, the registering, the whole thing. it's not out here doing half the job and dipping, no ma'am 💅

if you're calling this, you're basically handing the kernel your device and saying "here bestie, take care of her" and it does. iconic behaviour fr fr.

⭐ RETURN ⭐

• 0 on success 🎉 — we love a clean zero, that's the good ending
• a failure value on error 😭 — so like, always check it, don't just assume it slayed

👑 SEE ALSO 👑

• the kernel file ./drivers/net/can/ctucanfd/ctucanfd_pci.c — that's where she lives, go read the source, it's literally right there 🌈
• ctucan_pci_remove(9) — her counterpart, the one who cleans up after the party 🧚

---

ngl bestie, always check the return value. a failed probe is not the moment to be delusional 🙈
