_dpu_plane_color_fill(9)

💅 NAME 💅

okay so bestie, listen — _dpu_plane_color_fill is the little icon that enables color fill on plane. that's it. that's the whole vibe. ✨

this is from the Kernel API Manual, section 9, so like… kernel-internals territory. buckle up 🎀

🌸 SYNOPSIS 🌸

void _dpu_plane_color_fill (struct dpu_plane *pdpu , uint32_t color ,
uint32_t alpha );

like literally that's the whole signature, no cap. it returns void — nothing comes back, it just does the thing 💅

🦋 ARGUMENTS 🦋

• pdpu — Pointer to DPU plane object. this is your main character, the plane you're about to paint on 🖌️
• color — the RGB fill color value, and the bit layout is very specific so do not freestyle it:
  • [23..16] → Blue 💙
  • [15..8] → Green 💚
  • [7..0] → Red ❤️
• alpha — 8-bit fill alpha value. and bestie, 255 selects 100% alpha — fully opaque, full send, no see-through energy 🫶

lowkey the bit-packing is the whole assignment here. RGB but reversed-order vibes. iykyk 🧚

🍓 reminder: this page ships from ./drivers/gpu/drm/msm/disp/dpu1, dated October 2026, and it's _dpu_plane_color_fill(9) in the Kernel API Manual. that's the whole ticket, bestie — go fill some planes 💜🌈⭐
