    drm/nouveau/kms/nv50: transition to atomic interfaces internally · 839ca903
    Ben Skeggs authored
    This commit implements the atomic commit interfaces, and implements the
    legacy modeset and page flipping interfaces on top of them.
    
    There's two major changes in behavior from before:
    
    - We're now making use of interlocks between core and satellite EVO
      channels, which greatly improves our ability to keep their states
      synchronised.
    - DPMS is now implemented as a full modeset to either tear down the
      entire pipe (or bring it back up).  This choice was made mostly
      to ease the initial implementation, but I'm also not sure what we
      gain by bring backing the old behaviour.  We shall see.
    
    This does NOT currently expose the atomic ioctl by default, due to
    limited testing having been performed.
