drm_object_...ty_get_value(9)

📦 version 7.3.1, in nixpkgs unstable

✨ drm_object_property_get_value(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil function from the DRM core and it's literally the "hey what's this property set to rn" girlie. let's get into it 🎀

🌸 NAME 🌸

drm_object_property_get_value — retrieve the value of a property 💅

🦋 SYNOPSIS 🦋

int drm_object_property_get_value (struct drm_mode_object *obj ,
                                   struct drm_property *property ,
                                   uint64_t *val );

✨ ARGUMENTS ✨

  • obj — the drm mode object you're pulling the property value from 🫶
  • property — the property you wanna retrieve, iykyk
  • val — your storage spot where the property value gets dropped off 📦

💜 DESCRIPTION 💜

so this function retrieves the software state of the given property for the given property — yes bestie, that's exactly what it says, it's a lil goofy but we move 😭💀

the big thing here: there's no driver callback to retrieve the current property value, so what you get back might be out of sync with the hardware — and that totally depends upon the driver and the property. so like… vibe check your expectations, ngl 🙈

atomic drivers: do NOT call this function directly, periodt. the core will read out property values through the various ->atomic_get_property callbacks instead. that's the main character behavior, not yours 💅👑

🔥 RETURN 🔥

  • Zero on success 🎉
  • an error code on failure 😭
