ata_sff_port_init(9)

💖 NAME 💖

Okay bestie, this is ata_sff_port_init(9) from the Kernel API Manual — the function that initializes an SFF/BMDMA ATA port. She's giving utility, she's giving setup, and she's literally here to get your port together. 🎀

✨ SYNOPSIS ✨

void ata_sff_port_init (struct ata_port *ap );

🎀 ARGUMENTS 🎀

• ap — the port to initialize. That's the whole argument, bestie; she's the port getting initialized. 💅

🦋 DESCRIPTION 🦋

okay so this gets called on port allocation to initialize the SFF/BMDMA specific fields. That's the assignment. Port allocated → SFF/BMDMA fields initialized → she's done. ✨

LOCKING: None. No locks here, bestie; it's giving "I don't do locking." 💀
