How to use video memory as system memory?

Question

Iron

Is this even real? Theoretically, this is quite real. For example, zram allocates data in RAM, which can also be swapped. And what if you do something different, but which will already be placed in the memory of the video card?
On computers with a terribly small amount of RAM (4 GB in my case) and a considerable amount of video card (1 GB in my case), while using about 50 megabytes of video memory, it would be nice to use the rest of the memory as system ...
