xdma_alloc_chan_resources(9)

💅 xdma_alloc_chan_resources — the "bestie, go get your channel some stuff" page ✨

okay so real talk, this is a page from the Kernel API Manual, section 9 — the kernel-API section, iykyk 🎀 — and it's all about one little function that gets a DMA channel its resources. no cap, that's the whole plot.

---

🌸 NAME 🌸

xdma_alloc_chan_resources — allocate channel resources 🫶

like, literally what it says on the tin: it allocates the resources for a channel. slay.

---

✨ SYNOPSIS ✨

int xdma_alloc_chan_resources (struct dma_chan *chan );

it returns an int, bestie — keep that in mind 👑

---

🦋 ARGUMENTS 🦋

it all lives in the kernel file ./drivers/dma/xilinx/xdma.c, and then we have:

• struct xdma_chan(9)
• struct xdma_desc(9)
• struct xdma_device(9)
• xdma_link_sg_desc_blocks(9)

and that's the whole page, bestie — short and sweet, main character energy only 🌈⭐

later babes 💖 this was the Kernel API Manual joint, from ./drivers/dma/xilinx, dated October 2026 — mwah, caught you up, periodt 🎀💅
