💖 drm_format_info_plane_width(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, it's giving study date energy and honestly? iconic. 🎀

✨ NAME ✨

drm_format_info_plane_width — gives you the width of a plane, when you already know the width of the first plane. that's it, that's the whole vibe 💅

---

🌸 SYNOPSIS 🌸

int drm_format_info_plane_width (const struct drm_format_info *info ,
int width , int plane );

look at her go, three args, no cap 🦋

🫶 ARGUMENTS 🫶

• info — the pixel format info, like the little ID card for whatever format we're dealing with 💳
• width — the width of the first plane, ok so this is the reference point, the main character if you will 👑
• plane — the plane index, i.e. which plane you're asking about 🔢

⭐ RETURN ⭐

the width of plane, given that the width of the first plane is width. literally exactly what it says on the tin, fr fr 💖

ngl, if you get the plane width wrong your buffers are gonna have a bad time 😭 get it right the first time, bestie 💀

mwah 💜 that's the page! this gem lives in ./include/drm, and the version on the tin is October 2026 — so mark your calendars, sincèrement your fave kernel girlie 🌸✨💅
