xilinx_vdma_..._interleaved(9)

💅 xilinx_vdma_..._interleaved(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for xilinx_vdma_..._interleaved(9) — yes, the title is giving long-distance relationship with underscores, but we move. This page is literally about xilinx_vdma_dma_prep_interleaved, and it's here to prep a descriptor for a DMA_SLAVE transaction. periodt. 💖

✨ NAME ✨

xilinx_vdma_dma_prep_interleaved — prepare a descriptor for a DMA_SLAVE transaction. no cap, that's the whole name section and it ate. 🎀

🧚 SYNOPSIS 🧚

struct dma_async_tx_descriptor * xilinx_vdma_dma_prep_interleaved
(struct dma_chan *dchan , struct dma_interleaved_template *xt , unsigned
long flags );

the signature is right there, bestie — struct dma_async_tx_descriptor *, xilinx_vdma_dma_prep_interleaved, and the three parameters. iconic formatting, honestly. 🦋

🌸 ARGUMENTS 🌸

• dchan — DMA channel. that's the channel bestie, the main character of the DMA situation. 💅
• xt — Interleaved template pointer. yes, xt is literally the interleaved template pointer, not me making it cute. 🎀
• flags — transfer ack flags. lowkey important, highkey still just transfer ack flags. ✨

🌈 RETURN 🌈

Async transaction descriptor on success and NULL on failure — so if it slays, you get the async transaction descriptor; if it doesn't, you get NULL. fr fr. 😭
