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 Jason Ekstrand (5): 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 (v2) 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) drivers/gpu/drm/i915/gem/i915_gem_create.c | 165 ++++++++-------- drivers/gpu/drm/i915/gem/i915_gem_dmabuf.c | 64 ++++-- drivers/gpu/drm/i915/gem/i915_gem_object.c | 13 +- drivers/gpu/drm/i915/gem/i915_gem_object.h | 4 + drivers/gpu/drm/i915/gem/i915_gem_ttm.c | 3 +- .../drm/i915/gem/selftests/i915_gem_dmabuf.c | 184 +++++++++++++++++- .../drm/i915/gem/selftests/i915_gem_migrate.c | 15 -- 7 files changed, 318 insertions(+), 130 deletions(-)
