      drm/i915/dsb: Pre allocate and late cleanup of cmd buffer · afeda4f3
      Animesh Manna authored
      Pre-allocate command buffer in atomic_commit using intel_dsb_prepare
      function which also includes pinning and map in cpu domain.
      
      No functional change is dsb write/commit functions.
      
      Now dsb get/put function is removed and ref-count mechanism is
      not needed. Below dsb api added to do respective job mentioned
      below.
      
      intel_dsb_prepare - Allocate, pin and map the buffer.
      intel_dsb_cleanup - Unpin and release the gem object.
      
      RFC: Initial patch for design review.
      v2: included _init() part in _prepare(). [Daniel, Ville]
      v3: dsb_cleanup called after cleanup_planes. [Daniel]
      v4: dsb structure is moved to intel_crtc_state from intel_crtc. [Maarten]
      v5: dsb get/put/ref-count mechanism removed. [Maarten]
      v6: Based on review feedback following changes are added,
      - replaced intel_dsb structure by pointer in intel_crtc_state. [Maarten]
      - passing intel_crtc_state to dsp-api to simplify the code. [Maarten]
      - few dsb functions prototype modified to simplify code.
      v7: added few cosmetic changes suggested by Jani and null check for
      crtc_state in dsb_cleanup removed as suggested by Maarten.
      v8: changed the function parameter to intel_crtc_state* of
      ivb_load_lut_ext_max() from intel_crtc. [Maarten]
      v9: error handling improved in _write() and prepare(). [Maarten]
