💅 via_tf_load(9) 💅

okay so bestie, welcome to the Kernel API Manual — today's main character is via_tf_load, and honestly? she's lowkey iconic. 🎀

---

✨ NAME ✨

via_tf_load — send taskfile registers to host controller 🦋

---

🌸 SYNOPSIS 🌸

void via_tf_load (struct ata_port *ap , const struct ata_taskfile *tf );

---

💖 ARGUMENTS 💖

• ap — the port that the output gets sent to 🫶
• tf — an ATA taskfile register set (yes, the whole set, no cap)

---

⭐ DESCRIPTION ⭐

She outputs the ATA taskfile to the standard ATA host controller. That's it, that's the vibe. ✨ Literally her whole job and she ate.

---

🔥 NOTE 🔥

Okay so this part is important, bestie — pay attention 👑

This exists to fix the internal bug of via chipsets, which will reset the device register after changing the IEN bit on the ctl register. 😭 So yeah, she's not just cute, she's a bug fix. Not me being obsessed with a chipset workaround.
