That starts to look better, but please change this function so that it
gets a amdgpu_ctx_mgr structure as first parameter and rename it to
amdgpu_ctx_mgr_fence_usage.

Maybe move everything from here till the end of the loop into a separate

That is indented to far to the right, the "s_fence..." should be below
the "dma_fence..." in the line above.

Please write this as "max = max(max, t1);".

Please keep the empty line between the declarations and the #endif.

Again, why do you need this? Just expose the raw data you have in the
context.

The VRAM and GTT usage should probably be determined in one call to
those functions, otherwise they are not really valid.

BTW: This isn't accurate. The same memory can be opened under multiple
handles.
Getting this from the VM subsystem would be better.
