ata_set_mode(9)

💅 ata_set_mode(9) — like, the Kernel API Manual page, but make it make sense

okay so bestie, welcome to the Kernel API Manual entry for ata_set_mode(9) ✨ this is the one that literally programs your ATA timings and then goes ahead and issues SET FEATURES - XFER — iconic behaviour, no notes 🎀

---

✨ NAME ✨

ata_set_mode — Program timings and issue SET FEATURES - XFER 🫶

---

🦋 SYNOPSIS 🦋

int ata_set_mode (struct ata_link *link , struct ata_device
**r_failed_dev );

---

🌸 ARGUMENTS 🌸

• link — the link where the timings are gonna get programmed, bestie. this is the one getting the glow-up 💅
• r_failed_dev — the out parameter for the failed device 👀 like, if something goes wrong, this is where the culprit gets named.

---

💖 DESCRIPTION 💖

So this is the standard implementation of the function that tunes and sets the ATA device disk transfer mode — think PIO3, UDMA6, etc. like it's literally picking your speed vibe and committing to it 🏎️✨

If ata_dev_set_mode fails, the pointer to the failing device gets returned in r_failed_dev. not me pointing fingers but like. it's pointing fingers 🫵😭

LOCKING: PCI/etc. bus probe sem. 🔒 that's the party rule, pls respect it.

---

👑 RETURN 👑

• 0 on success 🎉 slay
• negative errno otherwise 💀

okay and like, official sign-off time bestie 🎀 this little masterpiece lives in ./drivers/ata, it's dated October 2026, and yeah — it's ata_set_mode(9) all the way down 💜 go forth and program those timings, you absolute icon 🌟
