media_request_object_bind(9)

📦 version 7.3.1, in nixpkgs unstable

💖 media_request_object_bind(9) — like, the Kernel API Manual page you actually wanna read 💖

okay so bestie, we're in the Kernel API Manual today and the vibe is very "tying objects to requests". buckle up 🎀

✨ NAME ✨

media_request_object_bind — bind a media request object to a request. that's it. that's the whole job. 💅

🦋 SYNOPSIS 🦋

int media_request_object_bind (struct media_request *req , const struct
media_request_object_ops *ops , void *priv , bool is_buffer , struct
media_request_object *obj );

🌸 ARGUMENTS 🌸

  • req — the media request. the main character, the one everything gets attached to 👑
  • ops — the object ops for this object, i.e. the little instruction manual for how this thing behaves ✨
  • priv — a driver-specific priv pointer associated with this object. you do you, driver 🫶
  • is_buffer — set to true if the object is a buffer object. yes, this matters. keep reading, iykyk 💀
  • obj — the object. the whole point. the icon, the moment 🎀

🔥 DESCRIPTION 🔥

so what does it do? it binds this object to the request, and it sets the ops and priv values of the object too — that way you can find it later with media_request_object_find. no cap, that's the whole mechanic 🌈

⚠️ real talk: every bound object must be unbound or completed by the kernel at some point in time, otherwise the request will never complete. not "eventually". never. so don't leave your objects hanging like an unread group chat 😭

and when the request is released, all completed objects will be unbound by the request core code — so the core does have your back there, bestie 🫶

now the fun ordering bit, because this is lowkey the smartest part of the whole thing 🧠✨

  • buffer objects get added to the end of the request's object list
  • non-buffer objects get added to the front of the list

why? because this ensures that all buffer objects are at the end of the list, and that all non-buffer objects that they depend on are processed first. it's giving "get your dependencies in order first" energy, and honestly? obsessed 💅

and that's the page!! 🎀 it lives over in ./include/media and it's dated October 2026 — go forth and bind your objects responsibly, bestie, and remember: unbound objects = never-ending request = the actual worst timeline 💀💖 slay 🦋✨
