ata_port_detach(9)

💅 ata_port_detach 💅

Ok so bestie, welcome to the Kernel API Manual, and today's main character is ata_port_detach(9) — the function that handles ATA port detachment. Let's get into it 🫶

---

✨ NAME ✨

ata_port_detach — detach an ATA port in preparation of device removal 💫

---

🌸 SYNOPSIS 🌸

void ata_port_detach (struct ata_port *ap );

---

🎀 ARGUMENTS 🎀

• ap — the ATA port that's getting detached, no cap 🫡

---

💖 DESCRIPTION 💖

So what this does is: it detaches all the ATA devices and the SCSI devices that go with ap, and then it removes the associated SCSI host. That's the whole vibe.

And the iconic part? ap is guaranteed to be quiescent on return from this function — like, fully settled, nothing left running, completely chill 😌✨

LOCKING: Kernel thread context (may sleep). So yeah, she's allowed to nap, plan accordingly 💤

Obsessed with this list honestly, it's giving "who's who of libata." Also, kernel file ./drivers/ata/libata-core.c — that's where the magic lives, iykyk 📁
