RE: [PATCH 0/6] make ctx mgr global

["Liu, Monk" <Monk.Liu-5C7GfCeVMHo@public.gmane.org>]

David,

No matter what's the initial purpose of this patch is, I think this patch is needed, otherwise context switch judgment will be incorrect , e.g. process1 and process2 can both have a context id 99, and that will
Lead to incorrect skipping of PREAMBLE CE IB

Subject: [PATCH 0/6] make ctx mgr global

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
