🌸 snd_hdac_stream_start(9) 🌸

okay so bestie, we're in the Kernel API Manual today — yes, the Kernel API Manual, that's the manual name, we're fancy now 💅 — and this page is literally all about the one little function that gets your stream up and running. no cap.

✨ NAME ✨

snd_hdac_stream_start — start a stream. that's it. that's the whole vibe. 💖

🎀 SYNOPSIS 🎀

void snd_hdac_stream_start (struct hdac_stream *azx_dev );

like, it returns void, so don't go looking for a return value bestie, there isn't one 🫶

🦋 ARGUMENTS 🦋

  • azx_dev — the HD-audio core stream you wanna start. that's your girl. give her a start 🌸

⭐ DESCRIPTION ⭐

okay so here's the whole thing: this function starts a stream. that's the main character energy right there 👑

while it's doing that, it also sets start_wallclk — yes, exactly that, start_wallclk, write it down — and it sets the running flag. so the stream is officially running now, flag and all. periodt. 🔥

lowkey the whole job is three things: start the stream, set start_wallclk, set the running flag. no more, no less, iykyk.

🌈 SEE ALSO 🌈

so like, the kernel file for this one lives at ./sound/hda/core/stream.c — go say hi if you're nosy 💜

and here's the whole friend group, like genuinely every single one of them, no one left out (i would never 🙈):

okay that's the whole page, you ate that bestie 🍓 mwah 💋
