Re: Abnormal memory usage
but it starts to look like it's just GART/GTT after all?
Will see, don`t have much time for testing now

Re: Abnormal memory usage
Seems it is really GART/GTT after all. Memory usage is lower now. What can I do with this issue now?

Re: Abnormal memory usage
Principally nothing. RAM is there to be used.
The oddity is that you do not seem to be able to forcefully reclaim the memory.
Frt: does the reclamation attempt result in increased swap usage? What if you "swapoff" before?
And just to be sure: you did then not first start plasma again to draw /proc/meminfo from there, did you?
Also try head|tail for the memory allocation, in case there's a problem w/ streess: https://unix.stackexchange.com/a/254976
If you want/need to override the amdgpu behavior, you'd use those kernel parameters, but "just because" will most likely only result in inferior performance.

I did cat /proc/meminfo from tty1, not from plasma

I did swapoff before trying to reclaim (stress-ng). No result. Will try installing artix (someday) and report if it is fixed there
