💖 sata_pmp_attach(9) 💖

okay bestie, welcome to the Kernel API Manual entry for sata_pmp_attach(9) — the SATA PMP attach function. It’s lowkey iconic, and we’re gonna get through it together. ✨

---

🌸 NAME 🌸

sata_pmp_attach — attach a SATA PMP device. That’s the whole vibe: this is the function that gets a SATA PMP device hooked up. 💅

🎀 SYNOPSIS 🎀

int sata_pmp_attach (struct ata_device *dev );

🦋 ARGUMENTS 🦋

• dev — the SATA PMP device to attach. That’s the target, the main character, the one getting configured. 🫶

✨ DESCRIPTION ✨

okay so sata_pmp_attach() configures and attaches the SATA PMP device dev. It’s also the one responsible for allocating and initializing the PMP links — yes, it does the whole setup, not just the attach part. 💅

LOCKING: Kernel thread context (may sleep). So like, sleeping is allowed here — it’s that kind of context. 😴

💀 RETURN 💀

0 on success, -errno on failure. Slay when it’s zero; sad little negative errno when it’s not. 😭
