DRM_GEM_SHA...HELPER_FUNCS(9)

💖 NAME 💖

okay so bestie, this page is from the Kernel API Manual, section 9, and the header title is DRM_GEM_SHA...HELPER_FUNCS(9) — yes the ellipsis is literally part of how it's printed, iykyk.

The star of the show is DRM_GEM_SHADOW_PLANE_HELPER_FUNCS — it initializes struct drm_plane_helper_funcs for shadow-buffered planes. periodt. 💅

✨ SYNOPSIS ✨

It's giving just the macro name, no arguments:

DRM_GEM_SHADOW_PLANE_HELPER_FUNCS

🦋 DESCRIPTION 🦋

Drivers may use GEM BOs as shadow buffers over the framebuffer memory. That's the setup. 🌈

This macro initializes struct drm_plane_helper_funcs to use the rsp helper functions. no cap, that's the whole job. 💖
