do_pata_set_dmamode(9)

💖 NAME 💖

okay so this is do_pata_set_dmamode(9) from the Kernel API Manual, and the official one-liner is literally Initialize host controller PATA PIO timings. yes bestie, that's the exact description — we are not editing the lore 💅✨

✨ SYNOPSIS ✨

void do_pata_set_dmamode (struct ata_port *ap , struct ata_device *adev
       , int isich );

---

🎀 ARGUMENTS 🎀

• ap — Port whose timings we are configuring. it's giving "main character port energy" 🫶
• adev — Drive in question. the device we're looking at, fr fr.
• isich — set if the chip is an ICH device. lowkey important detail 👑

---

🦋 DESCRIPTION 🦋

Set UDMA mode for device, in host controller PCI config space. that's the whole vibe — short, iconic, and straight to the point 🌸

🔒 LOCKING

None (inherited from caller). so yeah, no locking here — it's inherited from the caller, bestie. don't come for this function about locks 😌
