dma_async_issue_pending(9)

okay bestie, this is the dma_async_issue_pending(9) page from the Kernel API Manual — it’s giving “flush the queue to hardware” energy, and honestly? iconic ✨

🌸 NAME 🌸

• dma_async_issue_pending — flush pending transactions to HW 💅

🦋 SYNOPSIS 🦋

void dma_async_issue_pending (struct dma_chan *chan );

🎀 ARGUMENTS 🎀

• chan — target DMA channel. that’s the one you’re pointing at, bestie 🫶

✨ DESCRIPTION ✨

So here’s the vibe: this function lets drivers push copies to HW in batches, and that reduces <pink>MMIO writes</pink> where possible. lowkey efficient, no cap 🔥
