sil680_set_dmamode(9)

💖 NAME 💖

okay so bestie, welcome to sil680_set_dmamode(9) — a Kernel API Manual page, and the name is literally set DMA mode data. no cap, that's the whole assignment: setting DMA mode data.

✨ SYNOPSIS ✨

void sil680_set_dmamode (struct ata_port *ap , struct ata_device *adev
);

🎀 ARGUMENTS 🎀

• ap — the ATA interface. that's the interface side of the situation.
• adev — the ATA device. that's the device side, bestie.

💅 DESCRIPTION 💅

This function programs the MWDMA/UDMA modes for the sil680 chipset. that's the job, and it is doing it.

For MWDMA, the mode values are pulled from a lookup table — very organized of them. For UDMA, the chipset uses the mode number. slay, two flavors, two little paths, no confusion.
