💅 media_device_register_entity_notify(9) — like, the whole vibe

okay so bestie, welcome to the Kernel API Manual 🎀 — this one lives in ./include/media and it's genuinely such a cute little function. it's giving "small but crucial", no cap.

✨ NAME ✨

media_device_register_entity_notify — registers a media entity_notify callback 🦋

like, that's it, that's the whole job. she registers. she notifies. she slays.

🌸 SYNOPSIS 🌸

void media_device_register_entity_notify (struct media_device *mdev ,
struct media_entity_notify *nptr );

two args, returns nothing (void), lowkey iconic for that 🫶

💖 ARGUMENTS 💖

  • mdev — the media device 💫 (the whole big media device energy, the main character here)
  • nptr — the media_entity_notify 🌈 (the callback struct you're handing over)

fr fr, just those two. nothing sketchy, nothing hidden.

👑 DESCRIPTION 👑

NOTE: ⭐ when a new entity is registered, all the registered media_entity_notify callbacks are invoked.

so basically: you register your notifier here, and then any time a brand new entity shows up, every single registered media_entity_notify callback gets called. not just yours. ALL of them. the whole group chat gets pinged 📣💀

like, the way that works is genuinely so clean — you don't have to go hunting for new entities yourself, the kernel just tells you. obsessed 😭💜

that's a whole friend group right there, ngl 🫶✨
