STRUCT MEDIA_GOBJ(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct media_gobj(9) — the Kernel API Manual moment

okay bestie, buckle up, because we're talking about struct media_gobj from the ✨ Kernel API Manual ✨ — it's giving "small struct, huge responsibilities" and honestly? iconic.

🌸 NAME 🌸

struct media_gobj — Define a graph object. that's it, that's the whole vibe. it defines a graph object 🫶

✨ SYNOPSIS ✨

struct media_gobj {
    struct media_device     *mdev;
    u32 id;
    struct list_head        list;
 };

no cap, that's the whole struct. three little members, living their best life 🎀

🦋 Members 🦋

  • mdev — a pointer to the struct media_device that owns this object. every gobj has a parent device, it's giving family energy 💖
  • id — the non-zero object ID identifier. lowkey important: the ID should be unique inside a media_device, because it's composed by MEDIA_BITS_PER_TYPE (to store the type) plus MEDIA_BITS_PER_ID (to store the ID). so yeah, it's a bit-packing situation and it's serving 🧚
  • list — list entry stored in one of the per-type mdev object lists. that's where it lives, that's its home 🏠

👑 Description 👑

All objects on the media graph should have this struct embedded. that's the rule, periodt. every single object on the media graph? needs this struct embedded. no exceptions, bestie 💅

🔥 SEE ALSO 🔥

the friend group is massive, so here's every single one of them, in the original order, no one left behind 🫶

and that's the whole page, bestie!! 🌈✨ this little icon lives over in ./include/media and the docs are stamped October 2026 — so if anyone asks, you now know struct media_gobj better than you know your own sleep schedule. go embed it in everything (the media graph objects, specifically). mwah 💋🎀
