How is the value of Graphics pipe calculated? also The value is too high to represent what is wrong with the system?

Like all the others, it's a direct status bit in the register. It means "GPU has any activity going".

In your image, either the GPU is hung, or you're trying to run a computing workload that's too large for your VRAM (mining cryptocurrency?). A normal game would be more spread over, and rarely use any block fully.

Graphics pipe This is the call to the amdgpu interface or other ways?

In addition The server is running on the game program, not mining procedures.

Graphics pipe This is the call to the amdgpu interface or other ways? Sorry, I don't understand?

In other words ,"Graphics pipe" and "VRAM" state is synchronized? Why VRAM will be reduced but Graphics pipe has been very high.

What is the relationship between "Graphics pipe" and "VRAM"?

clbr commented 7 years ago

There is no direct relationship? A gpu-using program can use 100% of the gpu while using little VRAM, and the opposite can also be true, a program can use all VRAM without using gpu.

Okay, I understand now, thanks
