bdx_probe(9)

✨ bdx_probe(9) ✨

okay so bestie, welcome to the bdx_probe page from the Kernel API Manual — this is the little function that gets your adapter out of bed in the morning 💖 it's giving "first day of school" energy fr fr.

---

🎀 NAME 🎀

bdx_probe — the Device Initialization Routine ✨ like, it's the function that shows up and makes the hardware exist, iykyk.

---

🦋 SYNOPSIS 🦋

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

that's it, that's the whole vibe check 🌸 two args, one int back. iconic.

---

💜 ARGUMENTS 💜

• pdev — the PCI device information struct 🫶 it's literally the whole personality of the device, all wrapped up in one pointer.
• ent — an entry in bdx_pci_tbl 👑 the matchmaker that said "yes, this device, this driver, shipping it."

---

🔥 DESCRIPTION 🔥

So here's the tea ☕ bdx_probe returns 0 on success and a negative value on failure — no cap, that's the contract. (negative = bad news bestie, don't ignore it 💀)

bdx_probe initializes an adapter that's identified by a pci_dev structure ✨ and the way it does that is a whole three-course meal:

1. the OS initialization 🍓
2. configuring of the adapter private structure 🎀
3. a hardware reset 🧚

all of that happens, in that order, and it's not optional, it's the whole main character arc 💅

also!! the functions and their order are used as explained in /usr/src/linux/Documentation/DMA-{API,mapping}.txt — yes girl, go read the docs, they're right there 🌈

ngl, don't sleep on the failure path — a negative return means something went sideways during init, and that's your cue to actually handle it 😭
