👑 sl82c105_bmdma_stop(9) 👑

okay bestie, welcome to sl82c105_bmdma_stop(9) from the Kernel API Manual — this is the DMA-engine-stop page, and it's lowkey iconic. 💅

✨ NAME ✨

sl82c105_bmdma_stop — DMA engine stop

🎀 SYNOPSIS 🎀

void sl82c105_bmdma_stop (struct ata_queued_cmd *qc );

🦋 ARGUMENTS 🦋

• qc — ATA command

💖 DESCRIPTION 💖

okay so the whole vibe is: reset the DMA engine each use as recommended by the errata document. no cap, every single use. ✨

this function is also called to turn off DMA when a timeout occurs during DMA operation. in both cases we need to reset the engine — literally both, bestie. 😭

we assume bmdma_stop is always called if bmdma_start as called. if not, then we may need to wrap qc_issue. that's the caveat, and it's giving “keep an eye on this” energy. 👀
