intel_audio_component_init(9)

okay so bestie, welcome to the intel_audio_component_init(9) page from the Kernel API Manual 💖 this one is short, sweet, and very “audio component registration core.”

💖 NAME 💖

intel_audio_component_init — initialize and register the audio component ✨

✨ SYNOPSIS ✨

void intel_audio_component_init (struct intel_display *display );

🎀 ARGUMENTS 🎀

• display — display device 🫶

🦋 DESCRIPTION 🦋

so here’s the tea: this registers a child component with the component framework, and that child will bind dynamically to the corresponding master component of the snd_hda_intel driver when the latter is registered. slay, dynamic binding. During binding, the child initializes an instance of struct i915_audio_component which it receives from the master. After that, the master can then start to use the interface defined by this struct. 💅

either side can break the binding at any point by deregistering its own component, after which each side’s component unbind callback is called. no cap, that’s the whole lifecycle vibe. 🦋

we ignore any error during registration and continue with reduced functionality (i.e. without HDMI audio). lowkey important, so don’t expect HDMI audio if registration goes sideways 😭
