hl_pci_probe(9)

💅 hl_pci_probe(9) — the kernel API manual, but make it make sense

okay so bestie, this is a page straight out of the Kernel API Manual, and it's about hl_pci_probe — the function that probes PCI habanalabs devices. yes it's a mouthful, no you're not dumb, let's go 🫶

---

✨ NAME ✨

hl_pci_probe — probe PCI habanalabs devices 🎀

Like, it goes and finds them. It checks on them. It says hi. Very main character energy honestly.

---

✨ SYNOPSIS ✨

int hl_pci_probe (struct pci_dev *pdev , const struct pci_device_id *id
);

that's it. that's the whole vibe. two pointers in, an int out 💖

---

✨ ARGUMENTS ✨

• pdev — pointer to pci device 🌸 (the actual device, the little guy we're probing)
• id — pointer to pci device id structure ⭐ (the ID card that tells us what kind of device it is)

---

✨ DESCRIPTION ✨

ngl this one is short and sweet: it's the standard PCI probe function for habanalabs device. 👑

What it does, step by step, no cap:

1. Create a new habanalabs device 🦋
2. Initialize it according to the device's type ✨

that's literally it. that's the whole job. it shows up, it makes a device, it sets it up right based on what type it is. iconic behaviour, honestly. periodt. 💅

fr fr though — if you're messing with device init you're in driver-land, so don't go changing things you don't understand, bestie 😭
