legacy_set_mode(9)

✨ legacy_set_mode(9) ✨

okay bestie, this one's from the Kernel API Manual, and it's giving vintage IDE energy 💅

🎀 NAME 🎀

legacy_set_mode — mode setting, no cap 🎛️

📜 SYNOPSIS 📜

int legacy_set_mode (struct ata_link *link , struct ata_device **unused
);

🧚 ARGUMENTS 🧚

• link — IDE link 🧵✨
• unused — Device that failed when error is returned 🫠

💖 DESCRIPTION 💖

So we're using a non standard set_mode function here. That's the whole vibe. We don't want to be tuned. 🙅‍♀️

The BIOS configured everything. Our job is not to fiddle. Just use whatever PIO the hardware is using and leave it at that. Literally.

When we get some kind of nice user driven API for control, then we can expand on this as per hdparm in the base kernel. Until then? Leave it alone, bestie 💀

no extra tuning, no extra drama — the hardware is already living its truth 🌈
