<pre>When running the display server (X11 or Wayland) on an Intel GPU and using an
AMD GPU as the primary, it wouldn't be terribly difficult to exchange X or
Y-tiled images instead of linear ones. This would certainly improve
performance on the Intel GPU and probably somewhat on the AMD GPU since
anything is better than linear. The idea would be to replace the
vkCmdCopyImageToBuffer with a compute pipeline that binds the PRIME image as a
buffer and does the swizzling in the shader to get X or Y-tiling.</pre>
