current amdgpu driver indeed always set GPU PAGE SIZE is 4096. In fact, our gpu supports bigger page size like 64KB, just we don't use it. I remeber previous amdsoc(old android kernel driver) used 64KB.

That is never the case: AMDGPU_GPU_PAGE_SIZE is always 4096, and PAGE_SIZE is always >= 4096 (an integer multiple of it). -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer
