ns87415_bmdma_stop(9)

💅 ns87415_bmdma_stop — like, the Kernel API Manual page, bestie ✨

Okay so picture this: you're deep in the ns87415 driver, the DMA party is winding down, and somebody's gotta call it. That's this function. It's from the Kernel API Manual, section 9 (iykyk), and it is exactly one job and she does it.

🌸 NAME 🌸

ns87415_bmdma_stop — literally just End DMA transfer. That's the whole vibe. No notes. Periodt.

---

🦋 SYNOPSIS 🦋

void ns87415_bmdma_stop (struct ata_queued_cmd *qc );

Look at her. void return, so she gives nothing back (respect), and she takes exactly one argument. Chef's kiss.

---

🎀 ARGUMENTS 🎀

• qc — the Command block. Yes, it's a struct ata_queued_cmd *. Yes, you gotta hand her one. That's the assignment, bestie, that's the whole assignment.

---

✨ DESCRIPTION ✨

So here's what she does, plain and simple: she ends DMA mode and switches the controller back into PIO mode. That's it. That's the function. DMA out, PIO in, controller re-homed. Very main character of her honestly. 🔥
