ata_tf_to_fis(9)

✨ ata_tf_to_fis ✨

okay bestie, so this is a kernel API manual page, and we're about to get into the glow-up of ATA taskfiles → SATA FIS structures. it's giving "drivers/ata/libata-sata.c" main character energy, and honestly? we're obsessed. 💅

---

💫 SYNOPSIS 💫

void ata_tf_to_fis (const struct ata_taskfile *tf , u8 pmp , int is_cmd
, u8 *fis );

like, that's the whole vibe right there — one function, four args, zero drama. periodt. 🎀

---

🧚 ARGUMENTS 🧚

• tf — the taskfile you wanna convert. it's a const struct ata_taskfile *, so like, hands off, we're just reading it, no cap. 🦋
• pmp — port multiplier port. it's a u8, so a lil baby number, but it's important, okay? don't sleep on it. ✨
• is_cmd — this FIS is for command. int energy. like, is this a command FIS or nah? that's the question. 🔥
• fis — the buffer into which data will output. it's a u8 *, so you're handing over a pointer and the data gets written there. iconic. 👑

---

🌸 DESCRIPTION 🌸

so what does this actually do? it converts a standard ATA taskfile to a Serial ATA FIS structure (Register - Host to Device). literally that's it, that's the whole function. slay. 💖

LOCKING: inherited from caller. meaning: not our problem, bestie — whoever called us handles the locking. we just vibe. 🫶

fr fr, don't come for us about locking, we're just the messenger. 😭

and that's the tea, bestie. this page is from ./drivers/ata, dated October 2026, and it's literally called ata_tf_to_fis(9). now go convert some taskfiles and slay. 💅✨🎀🦋🌸🫶🔥👑🌈⭐💖
