STRUCT MTU3_FIFO_INFO(9)

💖 struct mtu3_fifo_info(9) 💖

✨ NAME ✨

okay so we’re in the Kernel API Manual, and struct mtu3_fifo_info is literally the HW FIFO description and management data — that’s the whole vibe, bestie 🫶

🌸 SYNOPSIS 🌸

the shape of it is right here, no cap:

struct mtu3_fifo_info {
    u32 base;
    u32 limit;
    unsigned long bitmap[BITS_TO_LONGS( MTU3_FIFO_BIT_SIZE)];
 };

🎀 Members 🎀

• base — the base address of fifo 📍
• limit — the bitmap size in bits 🔢
• bitmap — fifo bitmap in unit of MTU3_EP_FIFO_UNIT 🗺️

👀 SEE ALSO 👀

the kernel file ./drivers/usb/mtu3/mtu3.h is in the group chat, and the whole friend group is:

• enum mtu3_g_ep0_state(9)
• enum mtu3_dr_force_mode(9)
• struct qmu_gpd(9)
• struct mtu3_gpd_ring(9)
• struct otg_switch_mtk(9)
• struct ssusb_mtk(9)
• struct mtu3_ep(9)
• struct mtu3(9)

source/version check, bestie: ./drivers/usb/mtu3, dated October 2026, and yes the page is still struct mtu3_fifo_info(9) 💅✨ bye bestie, go read the header 🦋💖
