💅 sis630e_get_mac_addr (9) — Kernel API Manual 🎀

okay bestie, welcome to the Kernel API Manual entry for sis630e_get_mac_addr(9) — yes that's a real function name and yes it's a whole vibe ✨

---

🌸 NAME 🌸

sis630e_get_mac_addr — literally just: Get MAC address for SiS630E model 🫶

---

✨ SYNOPSIS ✨

int sis630e_get_mac_addr (struct pci_dev *pci_dev , struct net_device
*net_dev );

that's it, that's the whole signature, no cap 💅

---

🦋 ARGUMENTS 🦋

• pci_dev — the sis900 pci device 👑 (the actual hardware bestie we're talking to)
• net_dev — the net device to get address for 🎀 (this one's getting the glow-up, i.e. the MAC address)

---

💖 DESCRIPTION 💖

so the SiS630E model is built different, fr fr — it uses APC CMOS RAM to store the MAC address 🍓

and how do we get at that APC CMOS RAM? through the ISA bridge, obviously 🙈 that's the whole access path, don't question it.

then the MAC address gets read straight into net_dev->dev_addr ⭐ and that's the entire plot. main character energy, zero extra steps, periodt.
