[Intel-gfx] [PATCH 0/4] drm/i915/gem: Introduce a migrate interface

["Thomas Hellström" <thomas.hellstrom@linux.intel.com>]

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.
