🦋 drm_gem_ttm_vunmap(9) 🦋

okay so this little icon is from the Kernel API Manual, and she is here to explain how to vunmap a &ttm_buffer_object. bestie, it’s giving “short but important” energy, and we’re gonna get into it 💅

💖 NAME 💖

drm_gem_ttm_vunmap — vunmap &ttm_buffer_object

✨ SYNOPSIS ✨

void drm_gem_ttm_vunmap (struct drm_gem_object *gem , struct iosys_map *map );

🎀 ARGUMENTS 🎀

• gem — GEM object. that’s the main-character struct right there 👑
• map — dma-buf mapping. yes ma’am, that exact mapping 🫶

🦋 DESCRIPTION 🦋

so basically: this function unmaps a GEM object with ttm_bo_vunmap. that’s the whole assignment, and she ate 🔥

also — and this is lowkey important — it can be used as the drm_gem_object_funcs.vmap callback. periodt. that’s the callback hookup, no cap 💫
