STRUCT MLXBF_TMFIFO_IO(9)

✨ struct mlxbf_tmfifo_io — Kernel API Manual, but make it cute ✨

okay so bestie, this is the struct mlxbf_tmfifo_io page from the kernel API manual (that's the 9 section, iykyk). it's the structure of the TmFifo IO resource — and guess what, it does double duty for both rx & tx 🫶

🌸 SYNOPSIS 🌸

here's the whole lil' struct, verbatim, no cap:

struct mlxbf_tmfifo_io {
    void __iomem *ctl;
    void __iomem *sts;
    void __iomem *data;
 };

three pointers, all void __iomem *, and honestly? she's minimal and she ate 💅

🎀 Members 🎀

• ctl — the control register offset. literally just that. it's either TMFIFO_RX_CTL or TMFIFO_TX_CTL depending on which direction's vibes you're on 🔥
• sts — the status register offset. same deal, it's giving TMFIFO_RX_STS / TMFIFO_TX_STS energy ✨
• data — the data register offset. and yes, TMFIFO_RX_DATA / TMFIFO_TX_DATA, we love a consistent naming moment 💖

every member is an offset to a register — they're not the registers themselves, bestie, don't get it twisted 🙈

🦋 SEE ALSO 🦋

go read the actual source, it's iconic:

• struct mlxbf_tmfifo_vring(9)
• struct mlxbf_tmfifo_vdev(9)
• struct mlxbf_tmfifo_irq_info(9)

💜 the cute sign-off 💜

that's the whole page, bestie — short, sweet, slayed. it lives over in ./drivers/platform/mellanox, dated October 2026, and it's struct mlxbf_tmfifo_io(9) all the way down. go off, kernel girlies 👑🌈⭐
