STRUCT MTK_PCIE_SOC(9)

💅 struct mtk_pcie_soc(9) — like, the whole vibe

okay bestie, gather round, because we're talking about struct mtk_pcie_soc from the Kernel API Manual, and honestly? she's a whole personality test for MediaTek PCIe hosts. the way this struct exists purely to differentiate between host generations? iconic. periodt. 🌸

✨ NAME ✨

struct mtk_pcie_soc — differentiate between host generations

(yeah that's it, that's the job. she tells you which generation you're on, no cap 🫶)

---

🎀 SYNOPSIS 🎀

struct mtk_pcie_soc {
    unsigned int device_id;
    struct pci_ops *ops;
    int (*startup)(struct mtk_pcie_port *port);
    int (*setup_irq)(struct mtk_pcie_port *port, struct device_node
*node);
    enum mtk_pcie_quirks quirks;
 };

like, look at her. five fields. clean lines. main character energy fr fr 💅

🦋 Members 🦋

not me listing every single one because every single one MATTERS:

• device_id — the device ID which this host need to be fixed. lowkey the whole reason she's here 🎯
• ops — pointer to configuration access functions. this is where the config-space touching happens, iykyk ✨
• startup — pointer to controller setting functions. she gets the controller up and running 🚀
• setup_irq — pointer to initialize IRQ functions. interrupts don't set themselves up, bestie 😭
• quirks — PCIe device quirks. the ✨special little exceptions✨, and yes, struct mtk_pcie_soc's quirks field is of type enum mtk_pcie_quirks — say that five times fast 💀

ngl, this is a function-pointer kinda struct. every field is either an ID, a pointer, or an enum. no sneaky surprises. we love a predictable queen 👑

🌈 SEE ALSO 🌈

go read these next, bestie, they're all in Kernel file ./drivers/pci/controller/pcie-mediatek.c:

• enum mtk_pcie_quirks(9)
• struct mtk_pcie_port(9)
• struct mtk_pcie(9)
• mtk_pcie_retrain(9)

and that's the whole page, mwah 💖 this one lives over in ./drivers/pci/controller, dated October 2026, and it's page struct mtk_pcie_soc(9) of the Kernel API Manual — go off, you gorgeous function-pointer-filled struct 🎀✨🦋
