fsl_dma_abort_stream(9)

💅 fsl_dma_abort_stream — Kernel API Manual, section 9

Ok so bestie, welcome to the glow-up era of fsl_dma_abort_stream(9). This one's a kernel API manual page, and it's literally the whole "hey ALSA, the DMA just quit" announcement pipeline. Let's get into it ✨

---

✨ NAME ✨

fsl_dma_abort_stream — tell ALSA that the DMA transfer has aborted 🛑💔

---

🎀 SYNOPSIS 🎀

void fsl_dma_abort_stream (struct snd_pcm_substream *substream );

That's it. That's the whole flex. Returns void, takes one arg, no drama 🌸

---

🦋 ARGUMENTS 🦋

• substream — honestly? undescribed. 😭 That's genuinely all the original says about it, so that's all I'm gonna say about it. Not me making up lore for a parameter that the docs left on read 🙈

---

💖 DESCRIPTION 💖

So here's the vibe: this function should be called by the ISR whenever the DMA controller halts data transfer. That's the entire job description, and she ate. 🫶

Bestie, key deets: it's the ISR that calls this, and the trigger is the DMA controller halting data transfer. That's the when and the who — no cap, nothing extra. Slack responsibly, don't add steps that aren't in the source ✨
