drm_mode_convert_umode(9)

okay bestie, this is drm_mode_convert_umode(9), straight from the Kernel API Manual. Buckle up, it’s giving “tiny but important” energy. 💖

🌸 NAME 🌸

drm_mode_convert_umode — convert a modeinfo into a drm_display_mode. That’s the official one-liner, and yes, that’s literally the whole vibe check. ✨

✨ SYNOPSIS ✨

The signature, exactly as it lives:

int drm_mode_convert_umode (struct drm_device *dev , struct
       drm_display_mode *out , const struct drm_mode_modeinfo *in );

🫶 ARGUMENTS 🫶

• dev — the drm device, bestie.
• out — the drm_display_mode to return to the user.
• in — the drm_mode_modeinfo to use.

💖 DESCRIPTION 💖

Convert a drm_mode_modeinfo into a drm_display_mode structure to return to the caller. That’s the whole assignment, no cap. 💅

🌈 RETURN 🌈

Zero on success, negative errno on failure. So: success is 0, failure is a negative errno. Periodt. 💀
