ata_dev_init_params(9)

💖 ata_dev_init_params 💖

okay so bestie, welcome to the ata_dev_init_params(9) page from the Kernel API Manual — yes it's a section 9 (kernel API) situation, we're in the big leagues now 🎀

---

✨ NAME ✨

ata_dev_init_params — literally just issues the INIT DEV PARAMS command. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

unsigned int ata_dev_init_params (struct ata_device *dev , u16 heads ,
       u16 sectors );

like, it hands you back an unsigned int, and you feed it a device plus two u16s. iconic signature ngl 💅

---

🎀 ARGUMENTS 🎀

• dev — the device the command is gonna get sent to. it's giving main character, everything happens to it 🫶
• heads — how many heads. and yes, it's a taskfile parameter — that's the phrase, i don't make the rules 💀
• sectors — how many sectors. also a taskfile parameter. besties heads and sectors are matching rn 😭

---

⭐ DESCRIPTION ⭐

LOCKING: Kernel thread context (may sleep)

that's the whole description babes. kernel thread context, and it may sleep — so do NOT come at it from some spicy atomic context, i'm serious 🙈

---

🔥 RETURN 🔥

• 0 — success, we ate 👑
• AC_ERR_* mask — otherwise. so basically any non-zero thing is an error mask in the AC_ERR_* family, periodt 💜
