intel_display_power_put(9)

📦 version 7.3.1, in nixpkgs unstable

💅 intel_display_power_put — a kernel API manual moment, brought to you by the Kernel API Manual ✨

okay so bestie, buckle up, because this one's from the Kernel API Manual and it's genuinely iconic in a quiet, load-bearing way 🫶

🎀 NAME 🎀

intel_display_power_put — the "okay I'm done with this, you can let go now" of power domain references 💖

✨ SYNOPSIS ✨

void intel_display_power_put (struct intel_display *display , enum
intel_display_power_domain domain , struct ref_tracker *wakeref );

that's it. that's the whole vibe. three args, zero drama, one very important refcount 🦋

🌸 ARGUMENTS 🌸

  • display — the display device instance. you know, the whole situation, the main character 👑
  • domain — the power domain you're referencing. like, which little slice of hardware are we talking about here 💅
  • wakeref — the wakeref that was acquired for the reference you're releasing right now. you gotta hand it back matching the one you got, iykyk 🔥

💜 DESCRIPTION 💜

okay so here's the tea 🍓: this function drops the power domain reference you got from intel_display_power_get. that's the whole job. no cap.

and like — here's the part that's giving main character energy — it might power down the corresponding hardware block right away if this happens to be the last reference. literally the moment you let go, if nobody else is holding on, the lights go out. periodt 💀

so yeah, it's a put. but it's a put with consequences, bestie 😭
