[PATCH 0/6] make ctx mgr global

[Chunming Zhou]

If we want to share semaphore/dependency across process across device, we
must make ctx id be global, so that we can index it everywhere.

Chunming Zhou (6):
  drm/amdgpu: use global ctx mgr instead of vm specified
  drm/amdgpu: clean up for amdgpu ctx
  drm/amdgpu: allocate progressively higher ids for ctx until idr
    counter wraps
  drm/amdgpu: ctx id should be removed when ctx is freed
  drm/amdgpu: use fence-array for ctx release
  drm/amdgpu: dependency is already signaled if ctx has been freed
