[PATCH 0/8] drm/i915: Migrate memory to SMEM when imported cross-device (v8)

[Jason Ekstrand]

This patch series fixes an issue with discrete graphics on Intel where we
allowed dma-buf import while leaving the object in local memory.  This
breaks down pretty badly if the import happened on a different physical
device.

v7:
 - Drop "drm/i915/gem/ttm: Place new BOs in the requested region"
 - Add a new "drm/i915/gem: Call i915_gem_flush_free_objects() in i915_gem_dumb_create()"
 - Misc. review feedback from Matthew Auld
v8:
 - Misc. review feedback from Matthew Auld
v9:
 - Replace the i915/ttm patch with two that are hopefully more correct

Jason Ekstrand (6):
  drm/i915/gem: Check object_can_migrate from object_migrate
  drm/i915/gem: Refactor placement setup for i915_gem_object_create*
    (v2)
  drm/i915/gem: Call i915_gem_flush_free_objects() in
    i915_gem_dumb_create()
  drm/i915/gem: Unify user object creation (v3)
  drm/i915/gem/ttm: Only call __i915_gem_object_set_pages if needed
  drm/i915/gem: Always call obj->ops->migrate unless can_migrate fails

Thomas Hellström (2):
  drm/i915/gem: Correct the locking and pin pattern for dma-buf (v8)
  drm/i915/gem: Migrate to system at dma-buf attach time (v7)
