✨ NAME ✨

okay bestie, this is the page for optidma_set_dma_mode(9) from the Kernel API Manual — and its whole thing is being the DMA setup callback 💅

---

🌸 SYNOPSIS 🌸

the signature is literally right here, no cap:

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

---

🎀 ARGUMENTS 🎀

two little arguments, bestie:

• ap — ATA port 🫶
• adev — Device ✨

---

🦋 DESCRIPTION 🦋

okay so here's the tea: the libata core provides separate functions for handling PIO and DMA programming. but the architecture of the Firestar makes it easier for us to have a common function, so we provide wrappers. periodt 💖
