sis900_probe(9)

💅 sis900_probe(9) — like, the Kernel API Manual moment

okay bestie, sit down, we're doing a probe function and honestly it's kind of a big deal 🎀 this one lives in the Kernel API Manual, and the name of the game is sis900_probe — say it with me now, sis900_probe ✨

---

🌸 NAME 🌸

sis900_probe — probe for sis900 device 🦋 like, go find out if this thing is even there

---

🧚 SYNOPSIS 🧚

int sis900_probe (struct pci_dev *pci_dev , const struct pci_device_id
*pci_id );

she takes two args and returns an int, periodt 💅

---

✨ ARGUMENTS ✨

• pci_dev — the sis900 pci device 💖 this is the actual card we're checking on, the main character of the whole operation
• pci_id — the pci device ID 🎀 the little name tag that says which device we're matching against

---

👑 DESCRIPTION 👑

so basically: check and probe the sis900 net device for pci_dev 🔍 that's the vibe check — is this thing real, can we set it up?

then she gets the mac address according to the chip revision 🧠✨ which is lowkey the whole reason this function is picky — different chips, different ways to dig out that address.

and after that? she assigns SiS900-specific entries in the device structure, like. as a treat 🫶 ie: sis900_open, sis900_start_xmit, sis900_close, etc. those are the function hooks that'll do all the actual work later 💅

no cap, this is the setup step. everything downstream is relying on her getting it right 😭
