mem_info_vram_used(9)

💖 mem_info_vram_used 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the page for mem_info_vram_used and it's honestly kind of a vibe 🦋

✨ DESCRIPTION ✨

so the amdgpu driver ships a sysfs API whose whole job is reporting the current total VRAM available on the device 👑 and the file that handles this is literally called mem_info_vram_used 📁

what does it give you? it returns the total amount of currently used VRAM in bytes 💅 that's it, that's the whole flex — one number, in bytes, no cap 🔥

no extra params, no secret flags, no drama — just read the file and get your byte count, periodt ✨
