[PATCH RESEND 0/5] drm/msm: cleanup private obj handling

[PATCH RESEND 0/5] drm/msm: cleanup private obj handling

[Dmitry Baryshkov]

Note: I'm resending this patch series as I haven't got any feedback from
the drm core maintainers to the first patch.

While debugging one of the features in DRM/MSM I noticed that MSM
subdrivers still wrap private object access with manual modeset locking.
Since commit b962a12050a3 ("drm/atomic: integrate modeset lock with
private objects") this is no longer required, as the DRM framework
handles private objects internally. Drop these custom locks, while also
cleaning up the surrounding code.

Dmitry Baryshkov (5):
  drm/atomic: add private obj state to state dump
  drm/msm/dpu: finalise global state object
  drm/msm/dpu: drop global_state_lock
  drm/msm/mdp5: migrate SMP dumping to using atomic_print_state
  drm/msm/mdp5: drop global_state_lock

[PATCH RESEND 1/5] drm/atomic: add private obj state to state dump

[Dmitry Baryshkov]

The drm_atomic_print_new_state() already prints private object state via
drm_atomic_private_obj_print_state(). Add private object state dumping
to __drm_state_dump(), so that it is also included into drm_state_dump()
output and into debugfs/dri/N/state file.

[PATCH RESEND 4/5] drm/msm/mdp5: migrate SMP dumping to using atomic_print_state

[Dmitry Baryshkov]

The Shared Memory Pool (SMP) state is a part of the MDP5's private
object state. Use existing infrastructure, atomic_print_state()
callback, to dump SMP state (which also makes it included into
debugfs/dri/N/state). This allows us to drop the custom debugfs file
too.
