devm_drm_pa...ge_add_typed(9)

📦 version 7.3.1, in nixpkgs unstable

💅 devm_drm_panel_bridge_add_typed(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're out here in the kernel, you've got a struct device *, you've got a struct drm_panel *, and you want a managed &drm_bridge plus a &drm_connector — except you're feeling spicy and you wanna pick the connector type yourself instead of letting the panel decide. that's this function. that's the whole vibe. ✨

✨ SYNOPSIS ✨

struct drm_bridge * devm_drm_panel_bridge_add_typed (struct device *dev
, struct drm_panel *panel , u32 connector_type );

it's giving "one function, three arguments, zero chill." 🦋

🌸 ARGUMENTS 🌸

  • dev — the device you're tying the bridge's lifetime to. it's a whole managed situation, so when dev goes bye-bye, the bridge goes with it. periodt. 💖
  • panel — the drm_panel getting wrapped up all cozy. must be non-NULL. like, fr fr, don't pass NULL here, that's not the move. 🙈
  • connector_type — the connector type, as a u32, picked from the DRM_MODE_CONNECTOR_* squad 👑 (that's literally the naming convention, the * is right there in the manpage, iykyk).

🦋 DESCRIPTION 🦋

so this bad boy is just like devm_drm_panel_bridge_add, except it forces the connector type to whatever you passed in as connector_type, instead of inferring it from the panel. no guessing, no vibes-based type detection, you're the main character and you decide. 💅

⚠️ okay bestie, important: this function is deprecated and should not be used in new drivers. the glow-up is real and you need to move on. use devm_drm_panel_bridge_add instead, and fix the panel drivers as necessary if they don't report a connector type. like, help them help themselves. 💀
