✨ swap_uv_columns(9) ✨

okay so this is a page from the Kernel API Manual and honestly? it's a little one but it's doing important work, bestie 💅

🌸 NAME 🌸

swap_uv_columns — swaps the u and v column of a given matrix. that's it. that's the whole vibe. two columns, one glow-up, we're flipping them 🦋

---

🎀 SYNOPSIS 🎀

void swap_uv_columns (struct conversion_matrix *matrix );

no return value, no drama, void and out 🫶

---

💖 ARGUMENTS 💖

• matrix — the matrix in which columns are swapped 👑 this is where the u column and the v column trade places, lowkey main character energy for a struct pointer.

and that's the whole thing, bestie!! 🍓 this cutie came out of ./drivers/gpu/drm/vkms and it's dated October 2026 — periodt, go flip some columns 💜⭐
