ata_ncq_prio_enable(9)

💅 ata_ncq_prio_enable — the Kernel API Manual, bestie edition 🎀

Okay so this one lives in the kernel API manual (yeah, the (9) section, we're in deep kernel territory, iykyk) and it's literally called ata_ncq_prio_enable. Obsessed already.

---

✨ NAME ✨

ata_ncq_prio_enable — Enable/disable NCQ Priority 🦋

---

🌸 SYNOPSIS 🌸

int ata_ncq_prio_enable (struct ata_port *ap , struct scsi_device *sdev
, bool enable );

---

🎀 ARGUMENTS 🎀

• ap — the ATA port of the target device, like, the port that the device you're poking at actually lives on 🫶
• sdev — the SCSI device
• enable — true = turn NCQ Priority on, false = turn NCQ Priority off. Literally a vibe switch, no cap 💅

---

🌈 DESCRIPTION 🌈

It's a helper that enables/disables the NCQ Priority feature. That's the whole thing — a cute little toggle helper doing its one job and doing it well ✨

---

💜 CONTEXT 💜

Any context. It takes and releases ap->lock. So like, it handles its own locking, you don't gotta worry about that part, bestie 🔥

---

⭐ RETURN ⭐

• 0 — OK. Status is stored into enabled 💖
• -ENODEV — Failed to find the ATA device 😭
• -EINVAL — NCQ Priority is not supported or CDL is enabled 💀

Okay that's the whole page and honestly? Kinda iconic. This one shipped out of ./drivers/ata in October 2026 — so yeah, she's from the future, we stan a forward-thinking manpage 🧚💜
