      drm/vkms: Add support for writeback · dbd9d80c
      Rodrigo Siqueira authored
      This patch implements the necessary functions to add writeback support
      for vkms. This feature is useful for testing compositors if you don't
      have hardware with writeback support.
      
      Change in V4 (Emil and Melissa):
      - Move signal completion above drm_crtc_add_crc_entry()
      - Make writeback always available
      - Use appropriate namespace
      - Drop fb check in vkms_wb_atomic_commit
      - Make vkms_set_composer visible for writeback code
      - Enable composer operation on prepare_job and disable it on cleanup_job
      - Drop extra space at the end of the file
      - Rebase
      
      Change in V3 (Daniel):
      - If writeback is enabled, compose everything into the writeback buffer
      instead of CRC private buffer
      - Guarantees that the CRC will match exactly what we have in the
      writeback buffer.
      
      Change in V2:
      - Rework signal completion (Brian)
      - Integrates writeback with active_planes (Daniel)
      - Compose cursor (Daniel)
