vmw_stdu_pri...tomic_update(9)

💖 NAME 💖

okay bestie, this page is from the Kernel API Manual and it's all about vmw_stdu_primary_plane_atomic_update — the function that formally switches STDU to new plane. 💅✨

✨ SYNOPSIS ✨

void vmw_stdu_primary_plane_atomic_update (struct drm_plane *plane ,
       struct drm_atomic_commit *state );

🎀 ARGUMENTS 🎀

• plane — display plane 🖼️
• state — only used to get crtc info 👀

🦋 DESCRIPTION 🦋

Okay so the main character move here: this function formally updates stdu->display_srf to the new plane, and binds the new plane STDU. 🫶

It gets called during the commit phase — that's when all the preparation have been done and all the configurations have been checked. So yeah, it's the “everything's prepped, let's actually do this” moment. 💅🔥
