mem_info_gtt_used(9)

💅 mem_info_gtt_used 💅

okay bestie, this is mem_info_gtt_used(9) from the Kernel API Manual, and it's a short one — no cap. The amdgpu driver provides a sysfs API for reporting the current total amount of used GTT. The file mem_info_gtt_used is used for this, and it returns the current used size of the GTT block, in bytes. literally that's the whole vibe check 💖
