xilinx_dma_device_config(9)

💅 xilinx_dma_device_config — Kernel API Manual ✨

ok so bestie, we're in the kernel API manual, section 9, and today's main character is xilinx_dma_device_config 💖 yes it's a whole function and yes it's literally here to configure your DMA channel. let's get into it 🎀

---

🌸 NAME 🌸

xilinx_dma_device_config — configure the DMA channel ✨

like, that's it, that's the job. she configures. she slays. periodt 💅

---

🦋 SYNOPSIS 🦋

int xilinx_dma_device_config (struct dma_chan *dchan , struct
       dma_slave_config *config );

no cap, that's the whole signature. two pointers, one int coming back at you 🫶

---

✨ ARGUMENTS ✨

• dchan — the DMA channel 💫 like, the actual channel you're configuring, bestie
• config — the channel configuration 🎀 all the settings she's gonna get

---

💜 RETURN 💜

0 always. 💀

fr fr — always zero. no dramatic error codes, no plot twists, no "it depends". she returns 0 and she moves on. iconic behavior honestly 👑

🌈 SEE ALSO 🌈

ok this is the part where the manpage goes feral and lists literally everything, and I mean everything. strap in bestie, we're going shopping 🛍️
