DRM_GEM_SIMP..._PLANE_FUNCS(9)

🦋 NAME 🦋

okay so this is DRM_GEM_SIMPLE_DISPLAY_PIPE_SHADOW_PLANE_FUNCS — and yes bestie, that is a whole entire name, we love a long one 💅 — and what it does is initializes struct drm_simple_display_pipe_funcs for shadow-buffered planes. That's the whole vibe. It's a macro from the Kernel API Manual, section 9, so you know it's legit kernel business ✨

🎀 SYNOPSIS 🎀

DRM_GEM_SIMPLE_DISPLAY_PIPE_SHADOW_PLANE_FUNCS

no arguments, no drama, just the macro name doing its thing 🫶

🌸 DESCRIPTION 🌸

so here's the tea ☕ — drivers are allowed to use GEM BOs as shadow buffers over the framebuffer memory. iconic behaviour, no cap.

and this macro? it initializes struct drm_simple_display_pipe_funcs so it uses the rsp helper functions. that's it, that's the whole job, and it ate 💅✨

ngl bestie this one's short but she's important — shadow buffers are literally the main character of this manpage 🧚💜

okay that's a wrap! this lil page lives in ./include/drm, it's dated October 2026, and it came to you straight from the Kernel API Manual (that's DRM_GEM_SIMP..._PLANE_FUNCS(9) to its friends) — mwah, go read the kernel docs, ily, bye 🍓💖
