drm_gem_end_...ow_fb_access(9)

okay bestie, welcome to the Kernel API Manual page for drm_gem_end_...ow_fb_access(9) 💖✨

🌸 NAME 🌸

drm_gem_end_shadow_fb_access — releases shadow framebuffers from CPU access 💅

✨ SYNOPSIS ✨

void drm_gem_end_shadow_fb_access (struct drm_plane *plane , struct
       drm_plane_state *plane_state );

🎀 ARGUMENTS 🎀

• plane — the plane 🫶
• plane_state — the plane state of type struct drm_shadow_plane_state ✨

🦋 DESCRIPTION 🦋

okay so this function implements struct drm_plane_helper_funcs.end_fb_access — that's literally its whole main-character job 👑

It undoes all effects of drm_gem_begin_shadow_fb_access in reverse order. Like, all the effects, and in reverse order — the sequence is giving cleanup-with-a-plan, no cap 😭💅
