💅 zynqmp_dma_start(9) 💅

okay so this is a page from the Kernel API Manual bestie, and it's about one (1) tiny lil function that kicks a DMA channel into gear. short page, big main character energy ✨

🦋 SYNOPSIS 🦋

void zynqmp_dma_start (struct zynqmp_dma_chan *chan );

🎀 ARGUMENTS 🎀

• chan — literally just the ZynqMP DMA channel pointer. that's the whole parameter. she takes one (1) pointer and she starts her. 🫶
