snd_hda_set_power_save(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the snd_hda_set_power_save(9) page from the Kernel API Manual 💖 this is the whole vibe: a tiny HD-audio function about autosuspend delay, and we're reading it together like it's the group chat's main character.

🌸 NAME 🌸

<pink>snd_hda_set_power_save</pink> — reprogram autosuspend for the given delay. That's the name, bestie, iconic and to the point ✨

✨ SYNOPSIS ✨

Here's the signature, copied exactly so nobody comes for me:

void snd_hda_set_power_save (struct hda_bus *bus , int delay );

🎀 ARGUMENTS 🎀

  • bus — HD-audio bus. Main character energy, fr.
  • delay — autosuspend delay in msec, and 0 = off. So the <hotpink>off switch</hotpink> is literally 0 = off, no cap 💅

💅 DESCRIPTION 💅

It literally synchronizes the runtime PM autosuspend state from the power_save option. That's the plot, bestie 🎀 periodt.
