[PATCH 0/6] Experimental P2P buffer sharing

[Felix Kuehling]

This patch series adds experimental P2P buffer sharing. It's disabled
by default and can be enabled with amdgpu.p2p_sharing=1.

TODO:
* Add a whitelist of chipsets that support P2P access
* Refine UVD/VCE handling on newer IP versions with GPUVM support
* Handle foreign BOs in DC path
* Test for regressions in existing multi-GPU buffer sharing use cases

Amber Lin (1):
  drm/amdgpu: handle foreign BOs in the VM mapping

Christian König (4):
  drm/amdgpu: disallow foreign BOs for UVD/VCE
  drm/amdgpu: disallow foreign BOs in the display path
  drm/amdgpu: separate BO from GEM object
  drm/amdgpu: enable foreign DMA-buf objects v2

Felix Kuehling (1):
  drm: Add helper to check exporting driver of a DMA-buf
