I can get the address of the linear frame buffer with a function that I create but this is a physical address. How can I translate this address to a virtual address or if it is not possible how can I get the virtual address of the LFB?

Good question. Is the memory or frame buffer on the video adapter address space? Or in the RAM (does TLB matter?) Then is the FrameBuffer in virtual memory like hard drive or USB ? How ??
