okay so bestie, welcome to the Kernel API Manual — yes we're literally in the kernel manual, and yes this page is short, but it's iconic and we're gonna treat it right 🎀

🌸 NAME 🌸

amdtp_stream_pcm_prepare — like, get your PCM device all prepped and ready to run ✨

🦋 SYNOPSIS 🦋

void amdtp_stream_pcm_prepare (struct amdtp_stream *s );

🎀 ARGUMENTS 🎀

  • s — the AMDTP stream. that's it. that's the whole argument. she's the main character here 👑

💖 DESCRIPTION 💖

So here's the vibe: you should call this function from the PCM device's .prepare callback. that's literally the assignment. no cap.

like, this is the "get ready for me" moment — your PCM device is hitting its .prepare callback and this function is who you invite. periodt. 💅

ok but fr fr, the manpage says "should be called from" — that's the whole description, bestie, I'm not gonna invent extra lore for you 🙈
