💅 drm_connector_set_orientation_from_panel 💅

okay so bestie, this one's straight out of the Kernel API Manual and it's honestly kinda iconic — it's the little helper that hands your connector its vibe check (aka its panel_orientation) by asking the panel itself. no cap, the panel is the main character here 🫶

✨ NAME ✨

drm_connector_set_orientation_from_panel — set the connector's panel_orientation from the panel's callback. literally that's the whole gig 💖

🌸 SYNOPSIS 🌸

int drm_connector_set_orientation_from_panel (struct drm_connector
       *connector , struct drm_panel *panel );

🎀 ARGUMENTS 🎀

  • connector — the connector you're init-ing the panel-orientation property for. it's giving "who am I and which way is up" energy 🦋
  • panel — the panel that can actually provide the orientation info. she knows things 💅

🦋 DESCRIPTION 🦋

so here's the tea, bestie: drm drivers should call this function before drm_dev_register. periodt.

the orientation itself is obtained from the panel's .get_orientation callback — the panel tells you which way it's facing, and you just pass that along 😌

⭐ RETURN ⭐

  • Zero on success 🎉
  • negative errno on failure 😭

quick reminder bestie: call this before drm_dev_register, not after. timing is everything, iykyk 💀
