generic_set_mode(9)

💅 generic_set_mode(9) — like, the Kernel API Manual moment

okay bestie, buckle up, this one's from the Kernel API Manual and it's a short one but it matters.

---

✨ NAME ✨

generic_set_mode — mode setting, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

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

---

🦋 ARGUMENTS 🦋

• link — the link to set up 🫶 like, this is the one you're actually working on.
• unused — the returned device on error. yeah, that's its whole job. it just holds the device if things go sideways 😭

---

👑 DESCRIPTION 👑

so here's the tea: this is a non standard set_mode function. we don't want to be tuned. no cap. the BIOS already configured everything — that was its main character moment and it ate 💅 our job is not to fiddle.

we read the dma enabled bits from the PCI configuration of the device, and we respect them. periodt. that's it. that's the function 🌈

lowkey the whole point is: don't touch what the BIOS already slayed. read the DMA bits from PCI config, honour them, done. ✨
