xilinx_dma_reset(9)

💅 xilinx_dma_reset(9) — like, the whole glow-up

ok so picture this: you're deep in the Kernel API Manual, right, and this little icon pops up — xilinx_dma_reset(9). that's her. that's the page. bestie, she's a kernel function and she's here to reset a DMA channel, and honestly? she ate. 🎀

---

✨ NAME ✨

xilinx_dma_reset — Reset DMA channel 🔄

like literally, that's the whole job. she resets the channel. no notes. periodt.

---

🌸 SYNOPSIS 🌸

int xilinx_dma_reset (struct xilinx_dma_chan *chan );

ok so she takes one (1) argument and gives you back an int, and yes the chan parameter is a struct xilinx_dma_chan * because of course it is, it's giving very "pointer to driver-specific channel" realness 👑

---

🦋 ARGUMENTS 🦋

• chan — the driver specific DMA channel 💫 — literally the specific channel belonging to the driver, she's not out here resetting randoms, she's specific

---

💀 RETURN 💀

nnn this section is empty in the original. like, genuinely, there's nothing here. no return value documented, no nothing. the void. the silence. the audacity 😭🙈 so bestie, please do not come for me asking "but what does it return" — the manpage said nothing, and I'm respecting her privacy. fr fr.

and that's the page, bestie! 🌈 tiny function, huge see-also section, zero documented return values. iconic behaviour, no cap.
