🦋 zynqmp_dma_...esc_to_ctrlr(9) — Kernel API Manual 🦋

okay so bestie, this is the page for zynqmp_dma_update_desc_to_ctrlr from the Kernel API Manual. The header title is literally zynqmp_dma_...esc_to_ctrlr(9), and we are keeping every fact exactly where it belongs. no skips, no vibes-based omissions, periodt. 💅✨

✨ NAME ✨

zynqmp_dma_update_desc_to_ctrlr — Updates descriptor to the controller. that's the whole assignment, and she ate 💖

🎀 SYNOPSIS 🎀

the signature is giving void, so no return value bestie — she just updates and dips:

void zynqmp_dma_update_desc_to_ctrlr (struct zynqmp_dma_chan *chan ,
       struct zynqmp_dma_desc_sw *desc );

🔥 ARGUMENTS 🔥

two cuties go in:

• chan — ZynqMP DMA DMA channel pointer. yes, the original literally says DMA DMA, and we are not editing the queen's spelling 💀
• desc — Transaction descriptor pointer.
