dmaengine_terminate_all(9)

💅 dmaengine_terminate_all(9) — like, the whole kernel API manual tea 💅

okay so bestie, welcome to the Kernel API Manual page for dmaengine_terminate_all, and ngl this one is short but it's important, so stay with me 🫶

---

✨ NAME ✨

dmaengine_terminate_all — literally "Terminate all active DMA transfers" 💀 that's the whole vibe, it stops the transfers, all of them, the active ones ✨

---

🌸 SYNOPSIS 🌸

int dmaengine_terminate_all (struct dma_chan *chan );

it's giving int, it's giving a single pointer argument, it's giving very demure, very mindful signature 🎀

---

🦋 ARGUMENTS 🦋

• chan — the channel for which to terminate the transfers. yes bestie, that channel, the one you're pointing at, hand it over 💅

---

🔥 DESCRIPTION 🔥

okay so here's the part where I hold your hand and say it gently: this function is DEPRECATED. like, capital-D deprecated, the kernel is not in love with it anymore 😭

use either dmaengine_terminate_sync or dmaengine_terminate_async instead, fr fr ⭐

no cap, please don't build new stuff on this one, she's retired but still in the file 🎀
