💖 vmw_sou_prim...e_prepare_fb(9) 💖

okay bestie, welcome to the Kernel API Manual page for vmw_sou_prim...e_prepare_fb(9) — yes, the title really has that ellipsis, and we are keeping it exactly. This one is lowkey short and highkey useful: it’s all about allocating a backing buffer. ✨

🌸 NAME 🌸

• vmw_sou_primary_plane_prepare_fb — allocate backing buffer

✨ SYNOPSIS ✨

int vmw_sou_primary_plane_prepare_fb (struct drm_plane *plane , struct
       drm_plane_state *new_state );

🎀 ARGUMENTS 🎀

• plane — display plane
• new_state — info on the new plane state, including the FB

🦋 DESCRIPTION 🦋

The SOU backing buffer is literally our equivalent of the display plane. That’s the whole vibe. 💅

Returns 0 on success — that’s the win condition, bestie. ✅
