ata_dev_power_set_standby(9)

🌸 NAME 🌸

okay bestie, this is the ata_dev_power_set_standby(9) page from the Kernel API Manual 💖 — and it’s literally the “set a device power mode to standby” function. no cap.

✨ SYNOPSIS ✨

void ata_dev_power_set_standby (struct ata_device *dev );

🎀 ARGUMENTS 🎀

• dev — target device. that’s the whole argument, bestie.

💅 DESCRIPTION 💅

Okay so this function issues a STANDBY IMMEDIATE command to set a device power mode to standby ✨. For an HDD device, this spins down the disks — yes, literally spins them down. iconic behavior.

🔒 LOCKING: Kernel thread context (may sleep).
