drm_client_init(9)

📦 version 7.3.1, in nixpkgs unstable

💖 drm_client_init(9) — like, the Kernel API Manual entry, bestie 💖

okay so this is drm_client_init(9) from the Kernel API Manual and it is literally the glow-up moment where a DRM client gets born ✨

✨ NAME ✨

drm_client_init — Initialise a DRM client 🎀

🦋 SYNOPSIS 🦋

int drm_client_init (struct drm_device *dev , struct drm_client_dev
       *client , const char *name , const struct drm_client_funcs *funcs );

no cap, that's the whole signature, copy it exactly bestie 💅

🌸 ARGUMENTS 🌸

  • dev — DRM device. the whole vibe starts here 🫶
  • client — DRM client. this is the one getting its main character moment 👑
  • name — Client name. gotta have a name, iykyk 💜
  • funcs — DRM client functions (optional). optional!! she can show up with or without her accessories 🙈

💫 DESCRIPTION 💫

So this function initialises the client and opens a drm_file. that's two things, slay 🎀

Then you use drm_client_register to complete the process — like, init is not the final boss, register is where it all comes together ⭐

Heads up though: the caller needs to hold a reference on dev before calling this function. that's not optional, that's the rules, fr fr 🔥

And the client is freed when the drm_device is unregistered — so don't go freeing her yourself, that's not your job. see drm_client_release for that whole situation 👀

🌈 RETURN 🌈

Zero on success or negative error code on failure. that's it, that's the whole vibe check 💀
