Subject: [PATCH 0/4] share semaphore across process
Date: Thu, 18 Aug 2016 15:55:55 +0800	[thread overview]
Message-ID: <1471506959-905-1-git-send-email-David1.Zhou@amd.com> (raw)

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
