STRUCT MTK_MSI_SET(9)

✨ struct mtk_msi_set(9) ✨

okay so bestie, welcome to the Kernel API Manual — section 9, the one for kernel stuff, and today's main character is struct mtk_msi_set. no cap, it's giving humble but essential. let's get into it 💅

---

🌸 NAME 🌸

struct mtk_msi_set — literally the MSI information for each set 🎀 that's it, that's the vibe.

---

🦋 SYNOPSIS 🦋

here's the whole glow-up, verbatim, don't touch a single character:

struct mtk_msi_set {
    void __iomem *base;
    phys_addr_t msg_addr;
    u32 saved_irq_state;
 };

---

💖 Members 💖

okay so these are the three little icons of this struct, and yes we're going through every one of them 🫶

• base — the IO mapped register base. this is the home address of the registers, the whole main character location, iykyk ✨
• msg_addr — the MSI message address. the place the messages go, fr fr 📬
• saved_irq_state — the IRQ enable state that got saved at suspend time. like a little screenshot of your interrupt setup before it goes to sleep 😴💾

---

🔥 SEE ALSO 🔥

the kernel file that's the whole reason we're here:

./drivers/pci/controller/pcie-mediatek-gen3.c

and the rest of the squad, all of them, no skipping 🙈:

• struct mtk_gen3_pcie_pdata(9)
• struct mtk_gen3_pcie(9)
• mtk_pcie_config_tlp_header(9)
• mtk_intx_eoi(9)

go read them, they ate 👑

ngl this one's small but she's important — three members and she's carrying the MSI info for an entire set 💀

alright bestie, that's the page 🌈🦋💜 shoutout to the source <pink>./drivers/pci/controller</pink>, October 2026 — and yeah, your girl struct mtk_msi_set(9) is out here living her best kernel life. mwah, go read the source, periodt 🎀✨👑
