xdma_device_config(9)

💅 xdma_device_config(9) — the Kernel API Manual, but make it a group chat

Okay bestie, gather round, because this one's a little function in the Kernel API Manual and it's genuinely so straightforward you're gonna slay it. It lives in the kernel, it's called xdma_device_config, and its whole personality is "configure the DMA channel". That's it. That's the vibe. ✨

---

🎀 NAME 🎀

xdma_device_config — literally just configure the DMA channel, no cap 💅

---

🌸 SYNOPSIS 🌸

int xdma_device_config (struct dma_chan *chan , struct dma_slave_config
*cfg );

It returns an int, it takes a channel and a config, and the way that signature is formatted is a little chaotic but we respect it 🫶

---

🦋 ARGUMENTS 🦋

• chan — the DMA channel. Your main character. The thing getting configured 💖
• cfg — the channel configuration. The fit you're putting on the channel 👑

ngl there's no OPTIONS section, no exit statuses, no env vars, no examples, no warnings, and no bugs to warn you about here — the page is short and we're not gonna invent lore that isn't canon 🙈

⭐ the cute sign-off ⭐

this little page comes from ./drivers/dma/xilinx (that's the source, bestie) and the version/date stamp on it says October 2026 — so yeah, it's giving very much "written for the future" energy 🌈✨

go configure that channel, you absolute icon 💜🎀
