STRUCT PCH_PHUB_REG(9)

✨ struct pch_phub_reg(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for struct pch_phub_reg and honestly? it's giving "small struct, big responsibilities" 💅 this is the page where we meet the PHUB register structure — yes, that's the NAME, and yes, we're doing it properly: struct pch_phub_reg — PHUB register structure 🎀

---

🌸 SYNOPSIS 🌸

here's the whole vibe, character for character, no cap:

struct pch_phub_reg {
    void __iomem *pch_phub_base_address;
    void __iomem *pch_phub_extrom_base_address;
    u32 pch_mac_start_address;
    u32 pch_opt_rom_start_address;
    enum pch_phub_type ioh_type;
    struct pci_dev *pdev;
 };

like… six fields and every single one of them is a main character 🫶

---

👑 Members 👑

let's do a little meet-and-greet with the squad, field by field, because they all matter:

• pch_phub_base_address — the register base address 🏠 this is home base, literally.
• pch_phub_extrom_base_address — the external rom base address 📦
• pch_mac_start_address — the MAC address area start address 🧚 where the MAC party starts.
• pch_opt_rom_start_address — the Option ROM start address ⭐
• ioh_type — Save IOH type 🗂️ (type is enum pch_phub_type, if you were wondering, and it absolutely is in the synopsis above 💜)
• pdev — pointer to pci device struct 🔌 the classic.

no notes, no skips — every member got its moment, periodt ✨

and that's the whole page, bestie!! 🦋 this little gem comes from ./drivers/misc and it's dated October 2026, and the title on the tin is still struct pch_phub_reg(9) — mwah, sending you off with a kiss and a kernel module 🍓💖
