zynqmp_dma_free_descriptors(9)

💅 zynqmp_dma_free_descriptors(9) ✨

okay so first things first, bestie — this page lives in the Kernel API Manual, and the function we're simping over today is zynqmp_dma_free_descriptors. the name lowkey says it all: it frees channel descriptors. that's the whole vibe. periodt.

🌸 SYNOPSIS 🌸

void zynqmp_dma_free_descriptors (struct zynqmp_dma_chan *chan );

that's it. that's the whole signature. she's void, she takes one pointer, she does not return a thing — no cap, literally nothing comes back out. 🫶

🎀 ARGUMENTS 🎀

• chan — ZynqMP DMA channel pointer. that's the one and only thing she needs from you: hand her a pointer to the ZynqMP DMA channel and she'll take it from there. that's it. that's the whole ask. 💖
