💅 amdtp_stream_pcm_abort — bestie's guide to yeeting a PCM device

okay so this is a page straight out of the Kernel API Manual, and it's literally about aborting a running PCM device. yes, we're in kernel-land, we're in sound/firewire, we're doing the thing. put your hair up, it's about to get real 🎀

✨ NAME ✨

amdtp_stream_pcm_abort — abort the running PCM device 🛑

like, actually stop it. asynchronously. you'll see.

✨ SYNOPSIS ✨

void amdtp_stream_pcm_abort (struct amdtp_stream *s );

no return value, it just goes and does the thing. void energy, honestly iconic 💅

✨ ARGUMENTS ✨

  • s — the AMDTP stream about to be stopped 💀 yeah, the one you're already planning to kill. give her a name and pass her in.

✨ DESCRIPTION ✨

so here's the vibe check: if the isochronous stream needs to be stopped asynchronously, you call this function first to stop the PCM device. order matters, bestie — PCM goes down before the isochronous stream does 🫶

that's it, that's the whole function. small but mighty. not me being obsessed with a two-sentence manpage ✨

mwah, that's the page!! brought to you by ./sound/firewire and dated October 2026 — timestamp slay, no cap. stay safe out there in the kernel, and remember: abort the PCM first, then the stream. periodt 👑💜🌸
