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.
Jason Ekstrand (5): drm/i915/gem: Check object_can_migrate from object_migrate drm/i915/gem: Refactor placement setup for i915_gem_object_create* drm/i915/gem: Unify user object creation drm/i915/gem/ttm: Place new BOs in the requested region drm/i915/gem/ttm: Respect the objection region in placement_from_obj
Thomas Hellström (2): drm/i915/gem: Correct the locking and pin pattern for dma-buf (v6) drm/i915/gem: Migrate to system at dma-buf attach time (v6)
