STRUCT MTK_IPI_INFO(9)

✨ struct mtk_ipi_info(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 — today's main character is struct mtk_ipi_info, and honestly? it's giving "small struct, big responsibilities" energy. it's the mailbox message info for mtk-vcp-mailbox, and we're gonna get into it fr fr 🎀

---

🌸 NAME 🌸

struct mtk_ipi_info — mailbox message info for mtk-vcp-mailbox. no cap, that's literally what it is 💅

---

🦋 SYNOPSIS 🦋

here's the whole glow-up, exactly as it lives in the header:

struct mtk_ipi_info {
    void *msg;
    u32 len;
    u32 id;
    u32 index;
    u32 slot_ofs;
    u32 irq_status;
 };

---

⭐ Members ⭐

okay so every member gets its own moment, as it should 👑

• msg — the share buffer between IPC and mailbox driver. it's the communal hangout spot where both sides actually talk to each other 🫶
• len — message length. how long the message is, obviously, she's not gonna over-explain 😌
• id — this one is for identification purposes and is not actually used by the mailbox hardware. so she's here for the vibes and the labels, not the hardware, and we respect that 🙈
• index — the signal number of the mailbox message. the little numeric handle that says which signal we're on 🔥
• slot_ofs — data slot offset. yes, spelling is slot_ofs, not slot_offset, don't come for me 💀
• irq_status — captures incoming signals for the RX path. she's literally catching signals as they come in, iconique ✨

---

💜 Description 💜

it's used between IPC with mailbox driver. that's the whole vibe — this struct is the go-between, the group chat moderator between IPC and the mailbox driver, keeping everyone on the same page 💖
