Subject: [PATCH v4 00/13] drm/msm: drm scheduler conversion and cleanups

From: Rob Clark <robdclark@...omium.org>

Conversion to gpu_scheduler, and bonus removal of
drm_gem_object_put_locked()

v2: Fix priority mixup (msm UAPI has lower numeric priority value as
    higher priority, inverse of drm/scheduler) and add some comments
    in the UAPI header to clarify.

    Now that we move active refcnt get into msm_gem_submit, add a
    patch to mark all bos busy before pinning, to avoid evicting bos
    used in same batch.

    Fix bo locking for cmdstream dumping ($debugfs/n/{rd,hangrd})

v3: Add a patch to drop submit bo_list and instead use -EALREADY
    to detect errors with same obj appearing multiple times in the
    submit ioctl bos table.  Otherwise, with struct_mutex locking
    dropped, we'd need to move insertion into and removal from
    bo_list under the obj lock.

v4: One last small tweak, drop unused wait_queue_head_t in
    msm_fence_context

Rob Clark (13):
  drm/msm: Docs and misc cleanup
  drm/msm: Small submitqueue creation cleanup
  drm/msm: drop drm_gem_object_put_locked()
  drm: Drop drm_gem_object_put_locked()
  drm/msm/submit: Simplify out-fence-fd handling
  drm/msm: Consolidate submit bo state
  drm/msm: Track "seqno" fences by idr
  drm/msm: Return ERR_PTR() from submit_create()
  drm/msm: Conversion to drm scheduler
  drm/msm: Drop submit bo_list
  drm/msm: Drop struct_mutex in submit path
  drm/msm: Utilize gpu scheduler priorities
  drm/msm/gem: Mark active before pinning
