ata_scsi_start_stop_xlat(9)

💫 ata_scsi_start_stop_xlat 💫

okay so this is a page straight outta the Kernel API Manual — it's ata_scsi_start_stop_xlat(9), and bestie, it's literally the little translator that takes a SCSI START STOP UNIT command and turns it into something ATA can vibe with. let's get into it 🎀

---

✨ NAME ✨

ata_scsi_start_stop_xlat — the translator for the SCSI START STOP UNIT command. she speaks both languages, it's giving bilingual icon 💅

---

🌸 SYNOPSIS 🌸

unsigned int ata_scsi_start_stop_xlat (struct ata_queued_cmd *qc );

---

🦋 ARGUMENTS 🦋

• qc — your storage for the translated ATA taskfile. this is where the magic gets written, so hand her a real one, mmkay? 🫶

---

🔥 DESCRIPTION 🔥

so what she actually does: she sets up an ATA taskfile to issue STANDBY (that's the stop part) or READ VERIFY (that's the start part). no cap, that's the whole translation gig ✨

and here's a little aside the original drops in — perhaps these commands should be preceded by CHECK POWER MODE to see what power mode the device is already in. like, a lil vibe check before you commit, y'know? 🙈 [See SAT revision 5 at www.t10.org]

LOCKING: spin_lock_irqsave(host lock) — yes, that lock, hold it properly 💀

---

👑 RETURN 👑

• Zero on success 🎉
• non-zero on error 😭

the kernel file where she lives: ./drivers/ata/libata-scsi.c — go visit her sometime 💖

okay that's the whole page, you ate that 💅 stay in ./drivers/ata, and remember this lil masterclass dropped October 2026 in the Kernel API Manual — mwah, love u, go translate some commands 🧚💜
