it8213_set_piomode(9)

💅 NAME 💅

Okay bestie, welcome to the Kernel API Manual corner of the group chat 💖. Today’s main character is it8213_set_piomode — and it does exactly one iconic thing: Initialize host controller PATA PIO timings. Periodt.

✨ SYNOPSIS ✨

void it8213_set_piomode (struct ata_port *ap , struct ata_device *adev
);

🎀 ARGUMENTS 🎀

• ap — the port whose timings we’re configuring, aka the one getting the timing glow-up.
• adev — the device whose timings we’re configuring. It’s giving “device with a schedule” vibes.

🦋 DESCRIPTION 🦋

So what it actually does: it sets the PIO mode for the device, right in the host controller PCI config space. That’s the whole assignment, no cap.

LOCKING: None (inherited from caller). So the locking situation is literally inherited from whoever called you — don’t come for locks that aren’t yours 💅.
