sata_scr_write_flush(9)

💅 sata_scr_write_flush(9) — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the Kernel API Manual entry for sata_scr_write_flush(9) — she's a tiny function with a very specific job and honestly? she does it flawlessly. let's get into it ✨

---

✨ NAME ✨

sata_scr_write_flush — write the SCR register of the specified port and flush 🫧

like, she writes. then she flushes. that's the whole personality. iconic.

---

🌸 SYNOPSIS 🌸

int sata_scr_write_flush (struct ata_link *link , int reg , u32 val );

literally three args and a dream, no cap 💖

---

🦋 ARGUMENTS 🦋

• link — the ATA link you're writing the SCR for 🔗
• reg — which SCR you're writing, bestie. pick one 🎯
• val — the value going in. the actual content. the main character of the operation 👑

---

🧚 DESCRIPTION 🧚

okay so here's the tea: this function is identical to sata_scr_write — same vibes, same job — except this one performs a flush after writing to the register. that's the whole upgrade. write, then flush. she's not like other write functions 💅

LOCKING: None if link is ap->link. Kernel thread context otherwise. 🫶 like, keep that in mind or things get weird, and not in a cute way 😭

⭐ RETURN ⭐

• 0 on success — slay, it worked 🌈
• negative errno on failure — 💀 not slay, check your errno
