current amdgpu driver indeed always set GPU PAGE SIZE is 4096.<br>
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.<br>
<br>
correct me if I'm wrong.<br>

<br>
That is never the case: AMDGPU_GPU_PAGE_SIZE is always 4096, and<br>
PAGE_SIZE is always >= 4096 (an integer multiple of it).<br>
