drm_gem_dma_free(9)

✨ drm_gem_dma_free ✨

okay so bestie, welcome to the drm_gem_dma_free(9) page from the Kernel API Manual — it's giving "cleanup crew, but make it kernel" 💅

🌸 SYNOPSIS 🌸

void drm_gem_dma_free (struct drm_gem_dma_object *dma_obj );

🎀 ARGUMENTS 🎀

• dma_obj — the DMA GEM object you're about to free. like, this is the object, no cap 🫶

🦋 DESCRIPTION 🦋

So here's the tea, bestie 🍓: this function is the full send-off for a DMA GEM object. It does three very iconic things:

1. frees the backing memory of the DMA GEM object 😭
2. cleans up the GEM object state ✨
3. frees the memory used to store the object itself 💀

and there's more — if the buffer is imported and the virtual address is set, it gets released too. the way that it handles all of that in one call is lowkey obsessed-worthy 👑

fr fr, if you're freeing something, make sure it's actually yours to free — this is a cleanup function, not a vibe check 🧚

and that's the whole page, bestie 💖 it lives over in ./drivers/gpu/drm, dated October 2026, and it's part of the Kernel API Manual. slay, stay hydrated, and may your GEM objects always be freed exactly once 🌈👑💜
