💅 drm_connector_attach_scaling_mode_property — NAME

okay so bestie, this is the drm_connector_attach_scaling_mode_property page from the Kernel API Manual (yes the fancy kernel docs, we love her) — and the whole ~point~ of this function is literally just: attach atomic scaling mode property. That's it, that's the vibe check. 🎀

✨ SYNOPSIS ✨

int drm_connector_attach_scaling_mode_property (struct drm_connector
*connector , u32 scaling_mode_mask );

it's giving "small function, big responsibility" fr fr 💖

🫶 ARGUMENTS

  • connector — the connector you're attaching the scaling mode property onto. that's the one, that's the target 🎯
  • scaling_mode_mask — an or'ed mask of BIT(DRM_MODE_SCALE_. like, you OR together the BIT(DRM_MODE_SCALE_...) values you want. lowkey just a bitmask of which scaling modes are allowed, no cap ✨

🌸 DESCRIPTION 🌸

so what does she actually do?? this one is used to add support for scaling mode to atomic drivers. iconic behavior honestly 👑

the scaling mode gets set to drm_connector_state.scaling_mode, and you can then use it from drm_connector_helper_funcs->atomic_check for validation. so like — set it here, validate it there. it's giving teamwork 🦋

also important: this is the atomic version of drm_mode_create_scaling_mode_property. same energy, atomic flavor 💜

⭐ RETURN ⭐

  • Zero on success 🥳
  • a negative errno on failure 😭

🔥 SEE ALSO 🔥

okay bestie buckle up, this list is LONG and she ate every single one 💅 no skipping, we keep them all:

and that's the whole page bestie 🫶 sign-off time: this lil beauty lives in ./drivers/gpu/drm, dated October 2026, and she's page drm_connecto...ode_property(9) — yes the name is truncated, that's just how she rolls 💀✨ mwah, go attach some scaling modes 💜
