ata_sff_std_ports(9)

🌸 NAME 🌸

ata_sff_std_ports — initialize ioaddr with standard port offsets. This is the Kernel API Manual page for ata_sff_std_ports(9), and yes, she's a tiny utility with main character energy 💅✨

🎀 SYNOPSIS 🎀

It's giving one-liner, bestie:

void ata_sff_std_ports (struct ata_ioports *ioaddr );

💖 ARGUMENTS 💖

• ioaddr — IO address structure to be initialized. This is the struct getting the glow-up 👑

🦋 DESCRIPTION 🦋

Okay so this is a utility function, and its whole job is initializing data_addr, error_addr, feature_addr, nsect_addr, lbal_addr, lbam_addr, lbah_addr, device_addr, status_addr, and command_addr to standard offsets relative to cmd_addr. Literally setting the standard-port crew in place, no cap 🫶

It does not set ctl_addr, altstatus_addr, bmdma_addr, or scr_addr — those are not included, periodt 🙈
