[Bug 200387] amdgpu uses unusually high memory

https://bugzilla.kernel.org/show_bug.cgi?id=200387

--- Comment #26 from Michel Dänzer (michel@daenzer.net) --- (In reply to phoenix from comment #25)

Ok, I've tested the issue using Kernel 4.15.0-24-generic (Shipped with Ubuntu Mate) using the amdgpu driver and a 4.9.111 Kernel using the amdgpu-pro driver (17.40).

BTW, ideally you should only test with the kernel's own amdgpu driver, not with amdgpu-pro, because the later uses its own copies of core DRM and even some core kernel code, and has other modifications compared to the stock driver.
