有没有比制作驱动程序更简单的方法来完成这个实验？

Question

Am I overcomplicating things, or is this actually the easiest way of doing this?

I need a piece of software, that would allow me to force any given process on a system to use a specific GPU. The software should be able to force the process to switch GPU mid-execution (yes, I know this will cause a lot of issues, it's part some experiments I'm doing, to hopefully do something smart) (Linux btw)

Would it be correct to make a 'dummy driver' that allowed processes to use it as GPU, and then it could redirect the graphical processing to whatever GPU I wanted, or am I overcomplicating things? Is there an easier way to do this? Cause I kinda don't want to make a driver, but I can't really see any way around it.

Answer 1

I my view your actually undercomplicating the issue. A GPU is a highly specific device designed to do a gpu`s work like transforming patterns for geometric problems. It is far from a general purpose cpu. Yes, it is a cpu but with alot of specific instruction sets tobe utilized.

So i guess the answer to your question is yes, you can make such a program. A good hint is to get familiar with specifications like opengl or similar, in order to understand if and how your problem/programm can be made fit for such a engine and give you any advantage. Then you might have a path via Linux kms drivers combined with a wayland based application to interact with your gpu(s).
