ata_sff_tf_load(9)

hey bestie 👋 welcome to the ata_sff_tf_load(9) page from the Kernel API Manual 💖 this one is short, sweet, and very “taskfile registers to host controller, no cap.”

🌸 NAME 🌸

ata_sff_tf_load — send taskfile registers to host controller. Yes bestie, that's literally the whole name-vibe: it sends the taskfile registers over to the host controller ✨

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• ap — the port to which output is sent. That's where this function's output goes, periodt 💌
• tf — an ATA taskfile register set. The register-set cutie in question 🦋

🔥 DESCRIPTION 🔥

It outputs the ATA taskfile to the standard ATA host controller. That's the main-character move: taskfile goes out, host controller receives it, slay 🔥

LOCKING: Inherited from caller. The locking vibe is not generated here — it comes straight from whoever called you, fr fr 🫶
