oldpiix_set_dmamode(9)

🌸 NAME 🌸

oldpiix_set_dmamode(9) from the Kernel API Manual — okay bestie, this is the function that’s here to Initialize host controller PATA DMA timings ✨💅

✨ SYNOPSIS ✨

void oldpiix_set_dmamode (struct ata_port *ap , struct ata_device *adev );

🎀 ARGUMENTS 🎀

• ap — the port whose timings we’re configuring. She’s getting the timing glow-up 💖
• adev — the device to program. Yep, this is the one we’re programming, periodt.

🦋 DESCRIPTION 🦋

Set MWDMA mode for device, in host controller PCI config space. That’s the assignment, and it happens in the host controller’s PCI config space — no cap, that detail matters 🧚✨

LOCKING: None (inherited from caller). So the lock vibe check says none here — it’s inherited from the caller, bestie. Don’t come for this function about locking drama 🙈
