[PATCH 0/4] share semaphore across process

[Chunming Zhou]

after ctx id is valid in global side, we share semaphore across process based on BO sharing mechanism.
That means we map semaphore object to a bo, then sharing bo with other process, the other process can
get the semaphore object from the sharing bo.

Chunming Zhou (4):
  amdgpu: use drm_amdgpu_fence instead of amdgpu_cs_fence in semaphore
    structure
  amdgpu: add export/import semaphore apis
  amdgpu: add mutex for across process reason
  tests/amdgpu: add semaphore across process test
