We want to be able to explicitly migrate objects between gem memory
regions, initially for display and dma-buf, but there might be more
use-cases coming up.
Introduce a gem migrate interface, add a selftest and use it for
display fb pinning and dma-buf mapping.
This series should make the desktop light up on DG1 with DG1-enabled
mesa.
