iudma_reset_channel(9)

✨ iudma_reset_channel(9) ✨

okay bestie, so this is a page from the Kernel API Manual — yes, the actual kernel, the big one 🐧 — and we're talking about iudma_reset_channel, which is literally the "cut the DMA on ONE channel" girlie. not all of them. one. she's focused 💅

---

🌸 NAME 🌸

iudma_reset_channel — Stop DMA on a single channel. that's it, that's the whole vibe 🛑

---

🦋 SYNOPSIS 🦋

void iudma_reset_channel (struct bcm63xx_udc *udc , struct iudma_ch
*iudma );

it returns void, so like… she doesn't report back. she just does it and leaves. main character energy, no receipts 💀

---

🎀 ARGUMENTS 🎀

• udc — a reference to the device controller. like, the whole entire controller. she needs to know which one we're talking about before she touches anything 🫶
• iudma — the IUDMA channel to reset. this is the one getting the reset treatment. singular. one channel. not the group chat 🌈
