ata_scsi_mode_select_xlat(9)

💖 ata_scsi_mode_select_xlat(9) — live from the Kernel API Manual 💖

okay bestie, we are SO in the kernel docs right now. This page is literally ata_scsi_mode_select_xlat(9), and it’s giving “translator bestie” energy. Let’s get into it 🫶

---

✨ NAME ✨

ata_scsi_mode_select_xlat — Simulate MODE SELECT 6, 10 commands 💅

---

🛠️ SYNOPSIS 🛠️

unsigned int ata_scsi_mode_select_xlat (struct ata_queued_cmd *qc );

---

🧾 ARGUMENTS 🧾

• qc — storage for the translated ATA taskfile. That’s where the translated taskfile hangs out, periodt 🎀

---

💫 DESCRIPTION 💫

okay so this function converts a MODE SELECT command into an ATA SET FEATURES taskfile. That’s the main-character move ✨

lowkey assume this is invoked for direct access devices (e.g. disks) only. For other device types, there should be no block descriptor — no cap, that’s the rule 🫶

🔒 LOCKING 🔒

The locking vibe check is literally spin_lock_irqsave(host lock) — iconic, honestly 👑
