drm_mode_validate_size(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay bestie, we're in the Kernel API Manual and this page is drm_mode_validate_size(9) — the one whose whole job is to make sure modes adhere to size constraints. no cap. ✨

🎀 SYNOPSIS 🎀

enum drm_mode_status drm_mode_validate_size (const struct
       drm_display_mode *mode , int maxX , int maxY );

🌸 ARGUMENTS 🌸

  • mode — the mode to check. like, put it through the vibe check, bestie. 💅
  • maxX — maximum width. the width ceiling, fr fr.
  • maxY — maximum height. the height ceiling, periodt. 🦋

🦋 DESCRIPTION 🦋

Okay so this function is a helper — it can be used to validate modes against size limitations of the DRM device/connector. If a mode is too big, its status member is updated with the appropriate validation failure code.

The list itself is not changed. important! no list mutating, bestie — it's giving read-only energy. 🫶

✨ RETURN ✨

The mode status. that's it, that's the return. 😌
