🌸 DRM_GEM_SHADOW_PLANE_FUNCS(9) 🌸

okay bestie, welcome to the Kernel API Manual — this one's a macro page, it's short, it's sweet, and it's gonna make your shadow-buffered planes look flawless ✨

💅 NAME 💅

DRM_GEM_SHADOW_PLANE_FUNCS — the macro that initializes struct drm_plane_funcs for shadow-buffered planes. like, it sets up the whole vibe of your plane's function table for you 🎀

✨ SYNOPSIS ✨

DRM_GEM_SHADOW_PLANE_FUNCS

that's it. that's the whole thing. no args, no nothing, just the macro name sitting there being iconic 👑

🦋 DESCRIPTION 🦋

so here's the tea ☕ — drivers are allowed to use GEM BOs as shadow buffers layered over the framebuffer memory. think of it like a little understudy that's ready to step in 💃

this macro initializes struct drm_plane_funcs so it uses the rsp helper functions. that's it, that's the job — it wires your plane funcs up to the rsp helpers and dips, no cap 🫶
