💖 intel_lpe_audio_notify(9) 💖

okay so bestie, welcome to the Kernel API Manual — section 9, kernel developer land, no cap. today's main character is intel_lpe_audio_notify, and she's honestly iconic: she's the little messenger that tells the LPE audio driver "hey girl, the ELD changed" and also keeps i915 in the loop. lowkey essential, highkey underrated. 🎀

✨ NAME ✨

intel_lpe_audio_notify — notify lpe audio event audio driver and i915

like literally that's her whole job description and she ate. 💅

🌸 SYNOPSIS 🌸

void intel_lpe_audio_notify (struct intel_display *display , enum
       transcoder cpu_transcoder , enum port port , const void *eld , int
       ls_clock , bool dp_output );

she returns void, she takes six arguments, she does not take questions. 🦋

💜 ARGUMENTS 💜

  • display — the display device. your whole display situation, handed over. 🖥️
  • cpu_transcoder — the CPU transcoder, typed as an enum transcoder. yes bestie, this is the transcoder on the CPU. ⭐
  • port — the port, typed as an enum port. that's it, that's the argument. short and sweet fr fr. 🌈
  • eld — the ELD data, coming in as a const void *. treat it gently, it's const. 🙈
  • ls_clock — Link symbol clock, in kHz. units matter, always. 🔥
  • dp_output — a bool that answers one very important question: are we driving a DP output? 👑

🧚 DESCRIPTION 🧚

Notify lpe audio driver of eld change.

that's it. that's the whole vibe. she notifies the lpe audio driver that the ELD changed, periodt. no extra lore, no secret side quests — just a clean notification, delivered with main character energy. ✨
