[PATCH v2 00/22] drm/i915: Fix pre-g4x GPU reset, again (v2)

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

OK, so here's the full version of my rw_semaphore GPU vs. display reset
fix.

The only issue I'm aware of is that SKL watermark code still uses
obj->state and thus I have no clue what would happen if one tries to
run this on SKL. Untangling that would likely mean making the SKL wm
code more in line with the g4x/vlv/chv code (ie. track things in the
crtc state). I decided not to embark on that quest at this time.

Entire series available here:
git://github.com/vsyrjala/linux.git reset_commit_rwsem_4

Ville Syrjälä (22):
  drm/i915: Pass the new crtc state to color management code
  drm/i915: Pass the crtc state explicitly to
    intel_pipe_update_start/end()
  drm/i915: Eliminate obj->state usage in g4x/vlv/chv wm computation
  drm/i915: Pass proper old/new states to
    intel_plane_atomic_check_with_state()
  drm/i915: Eliminate obj->state usage from pre/post plane update
  drm/i915: Eliminate crtc->state usage from intel_update_pipe_config()
  drm/i915: Eliminate crtc->state usage from intel_atomic_commit_tail
    and .crtc_update()
  drm: Add drm_dynarray
  drm/atomic: Convert state->connectors to drm_dynarray
  drm/atomic: Remove pointless private object NULL state check
  drm/atomic: Convert private_objs to drm_dynarray
  drm/atomic: Make private objs proper objects
  drm/atomic: Pass old state to
    __drm_atomic_helper_crtc_duplicate_state() & co. explicitly
  drm/arm: s/old_state/old_mali_state/
  drm/mediatek: s/old_state/old_mtk_state/
  drm/atomic: Pass old state explicitly to .atomic_duplicate_state()
  drm/atomic: Fix up the kernel docs for the state duplication functions
  drm: Return the connector from drm_connector_get()
  drm/i915% Store vma gtt offset in plane state
  drm/i915: Refactor __intel_atomic_commit_tail()
  drm/atomic: Introduce drm_atomic_helper_duplicate_commited_state()
  drm/i915: Solve the GPU reset vs. modeset deadlocks with an
    rw_semaphore
