ata_pio_need_iordy(9)

ata_pio_need_iordy(9) is from the Kernel API Manual, and we’re gonna get you comfy with it, bestie 💖

✨ NAME ✨

ata_pio_need_iordy — check if iordy needed 💅

🌸 SYNOPSIS 🌸

unsigned int ata_pio_need_iordy (const struct ata_device *adev );

Copy it exactly, no cap ✨

🎀 ARGUMENTS 🎀

• adev — ATA device. That’s the icon we’re passing in 🫶

🦋 DESCRIPTION 🦋

Okay so: this checks if the current speed of the device requires IORDY. Various controllers use it for chip configuration. That’s literally it — a tiny vibe-check helper for chip setup 💅✨
